Aspire 3000 battery story: A few months back, when the exploding ACER Aspire 3000 laptop battery first started coming to the public attention, I wondered if my laptop would be affected. Eventually Dell set up a website to deal with it and published a list of PID’s (part numbers basically) that were affected and subject to recall. I remember looking through the chart for my serial number, and it wasn’t there. Great, no need to worry about my laptop catching fire and burning the building down while I was at work. I still left it unplugged while I was out though, just to be safe. Two weeks ago, while I was on vacation, I noticed my laptop battery seemed to discharge pretty quickly. I know that batteries start to degrade over time, after about 500 discharges and charges, but I didn’t think I was to that threshold yet. Rich’s Battery stopped charging when an internal counter hit 500 and just refused to ever work again. When this ACER Aspire 3000 battery was new, 18 months ago, I could last about 4.5 hours with the WiFi radio on and the screen at full brightness. It was pretty kick-ass. On the plane ride home from Vancouver, the battery died before I even finished watching a single DVD movie, with the screen brightness turned down a bit and the WiFi radio off. That was less than 50% of what it was when new. Not good. Within another week, I noticed it dying even quicker.

When using a laptop as a desktop replacement the laptop battery should not be left in for long periods of time. The laptop will over time discharge the ACER Aspire 3000 battery. Remove the battery,making sure that it is charged to 50% and store it in a dry, warm place. Ensure that it is wrapped protectively and nothing will be dropped on it. The battery should be re-installed every 3-4 weeks and allowed to fully discharge. Leaving a battery in storage for longer than this without using could cause the battery to fully discharge as the circuitry of the battery itself consumes power. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the laptop battery.

Laptop battery guide

1, laptop battery replacement
As people demand more and more mobile, notebook surge in sales in the past two years, laptop battery and increasingly thin, easy to carry. However, the mobile office is not only required the lighter the better laptop, its battery life determines whether you can successfully complete its work. The popularity of Centrino technology, making the current mainstream notebook standby time has reached 3-4 hours or more, can basically meet the needs of a half-day work. If you are only the notebook as a desktop machine to use, then the battery may not be concerned about. But with the popularity of wireless Internet access, limiting computer also only the power cord, in which case, using battery-powered chances greatly enhanced. However, the rechargeable battery is not a once and for all, its life will be based on charge and discharge times to decide. In the secondary market, the most criticism is the battery aging. Once the laptop loses battery, it becomes a mobile PC, worth plummeted, and inconvenient to use, I have a lot of close friends have been troubled by this problem. Under normal circumstances, the normal use of the laptop, in almost two years later have to face the battery problem, but at this time to ensure good notebook itself, configure enough to use. If the change sets a new, of course, huge waste; Well, the problem how to solve it? Currently we have four kinds of conventional ways to evoke the old books new life: purchasing a new battery; to buy compatible batteries; their replacement batteries; to buy an external lithium battery. However, speaking of these four methods have advantages and disadvantages, such as the original battery expensive; compatible batteries are also worried that the quality was not guaranteed; replacement batteries danger great; external lithium battery to bring inconvenience and so on. So for different users, HP 510 Laptop Battery which are several ways how to choose, how to avoid risk?

2, battery life, capacity, power in the end with whom the
Now the laptop battery laptop battery manufacturers have a more detailed description, we often can see the “six-core 4400mAh”, “4-pin 2200mAh” nominal value such as batteries, Acer Aspire 3000 Laptop Battery over time, we believe that directly determine the capacity of 4400mAh or 2200mAh Notebook working hours. With common 2200mAh, 3.6V batteries, for example, could have used some small way the composition of four batteries in series, their voltage is 14.4V, Capacity 2200mAh. Many 14-inch notebook, you might use 2 and 4 strings of 8-cell hybrid mode, the voltage remains at 14.4V, capacity doubled to reach 4400mAh, to ensure a longer usage time. However, the same is a 2200mAh, 3.6V batteries, if we adopt the 2 and 3 strings of 6 cores hybrid approach, its battery capacity it will still be 4400mAh, voltage down to 10.8V, if we just look at capacity, its use of time should be, and 8 the same cell battery. However, the 8-cell battery, after all, two more batteries, which are a waste it? It should be noted, when we talk about computer power consumption, the total nominal power use, rather than a simple yes-current. Sony pcga-bp2s Laptop Battery power should be multiplied by current, voltage, such as the previously mentioned 8-cell lithium battery, the power should be 63.36Wh, 6 cores for 47.52Wh, 4 cores for 31.68Wh. If according to this value, 8-cell lithium battery advantage reflected. The vendors nominal standby time, is derived by the following formula: The battery power (WH) / Notebook standby power consumption (W) = Standby time (h) such 63.36Wh 8-cell lithium battery, with power consumption in standby for the 10W notebook and come standby time is approximately 6 hours. However, in theory, in reality, they are not that simple. We all know that any energy efficiency has a problem, the battery is no exception. High-voltage battery, its efficiency is relatively low, even if the same total power, its use of time than low-voltage high-current battery short, we now have introduced a number of vendors have begun high-volume low-voltage battery (more parallel, less in series) to ensure that Notebook longer standby time, while the battery is almost no increase in cost. In short, both Wh or mAh, can not very intuitive manifestation of battery time, IBM ThinkPad R40 Series Battery and most manufacturers like to mark mAh, and will not cause too much confusion. Only in the purchase, you need more comprehensive consideration of many factors.

3, laptop battery more errors
Lithium batteries need to deep discharge: Obviously, for a memory effect of nickel-metal hydride batteries, the full full release will increase efficiency. However, there is no memory effect lithium batteries can be used at with the red, does not affect their capacity. When using an external power supply, it is best unplug the laptop battery: This paper presents this view is based on frequent charging and discharging may damage the laptop batteries, but does not know that do more harm than good. On the one hand, and now comes with smart Li-ion battery protection circuit, generally when the electricity when a drop of 5% or more will only start charging; the other hand, frequent plug the battery, may result in interface being exposed, but damage to the battery and notebook; and finally, Laptop Battery UPS has also played the role of a sudden power outage, the battery can guarantee that your computer continues to run, otherwise you will suffer some losses. The first charge should be 12 hours: After buying notebooks, sales staff will advise the you, the first charge should be 12 hours or more, aim is to “activate” the battery. In fact, now the majority of laptop battery with over-power protection circuit, as long as full point, the battery on the cut off contact with the AC at this time to “recharge” effect can only be a waste of energy and not a long time, Dell Inspiron 6000 Battery lithium batteries should be empty (full) power to save: This is the two diametrically opposite conclusion, but there are people who support. Said air power saved on the grounds that lithium batteries will slowly discharge, affecting life, and if air power, you do not have to worry about discharge. Said that full power saved on the grounds that since the lithium battery will discharge, if there is no electricity, it will definitely affect the life, just like people hungry after a fire, it will harm the body. In fact, these two arguments are not correct, and if you are a long time do not use lithium batteries, should be 60% of its capacity to save, this state, the battery discharge is relatively slow, and can be stored for long periods often do not charge and discharge of lithium batteries Impact: This view is also a one-sided, although there is no memory effect from the battery, but the frequent charge and discharge, or have an impact on life in general as far as power consumption less than 10% after the re-charging of battery life is conducive to growth. But if there are special needs, and occasionally advance charge, its impact will not be too much. In addition, try not to heat, cold environment, the use of batteries, which will affect its life. Some of the above to avoid errors, but also help to enhance battery life and, of course, the most important thing is when there is power to reduce the frequency of the use of batteries, so we need to purchase, repair the chances of the battery is greatly reduced.

I dont know how to fix my HP Pavilion dv3000 laptop series the laptop is working,have thje nececery sounds after i turn it on,but the problem is that the screen stays always black i conect the laptop to tv screen,it shous that evrething is working properly,even i reinstal the windows vista with new one ,by looking the tv screen and usind the butons on my lap top so i just have no idea way my screen is black,when the compiutar is working properly.Please if any body has ideas how to fix it.

 I’ve had the same problem too with my laptop. I have the same kind and I just learned how to solve this. Since you can connect your laptop to your tv, its easier. You have to go to start and in the search box type in system restore. It may take a minute but it will show up. Once it comes up, it will show you the date that you can restore it back to. You may not want to do that date so go to where it says choose a different restore point and click next. It will then display all the other dates that you can restore your laptop to. Choose one but maybe not the most recent one. You will have to close all other windows you have open before you start it. The system restore will then well, restore your laptop and restart it when it’s done. You should see the windows logo come on and you will be able to type in your password. Your screen should show.

 I have an hp pavilion dv6000 laptop and recently i have had similar problems. Most times when i turn it on the botton half of the screen is blank or fuzzy..thus making it unreadable. I actually pick up the computer by pulling on each side of the screen…just jiggling it and it always corrects the problem for me. It makes me think the problem is with the connection between the laptop and the screen. Works for me.interested if it would work for anyone else.seems like this is a common problem.

I’ve been running my HP Pavilion dv3000 Series laptop exclusively off the laptop AC adapter for about 1.5 years now and just the other day the laptop no longer runs off the adapter.What happens is that it will charge the battery if the laptop is off, but as soon as I turn on the laptop the adapter shuts off (light goes out) and the laptops begins running off the battery. To get it to charge the battery I have to unplug the AC adapter, shut down the laptop, then plug the adapter back into the socket and the laptop.Did I simply kill the AC adapter after 18 months of intense 3D gaming?

If the AC adapter will charge the battery at all, I say it’s at least not dead. Maybe not acting right, but not dead.On the other hand, if the AC adapter turns off when you turn the lappy on and try to run it off AC power, it would seem that perhaps you have a partial malfunction at the actual plug receptacle on the laptop. Combine that with the possible partial malfunction on the AC adapter, and you have a very frustrating situation.

A couple questions: Have you tried calling/emailing HP tech support about this issue? Have you looked around online for the specs on yours and other models of HP laptops, cross-reference with any friends who might have a compatible AC adapter that you/they know  is good? I would say that if the borrowed HP AC adapter works normally (charges / runs the laptop), it would indicate a problem with yours. If it acts the same, I say the power plug receptacle.

I may as well just remove the battery and run it off the AC adapter. I never bothered to try that, but then I really don’t care about the HP laptop battery other than as a backup if the power goes out (which is meaningless since in that case the router and the cable modem go down since they aren’t on a UPS battery backup?

The battery in my Li-ion DELL Inspiron 6000 battery is dying on me after just 14 months. It now gives me just about 20 minutes. I confess that I’m a heavy user. I don’t mind replacing the battery a little too soon. Here’s my problem:

The original DELL laptop battery (D5318) that came with my laptop has a 14.8v, 4400mAh rating. The ones available in the market are varied – combinations of 11.1v, 14.8v, 4400mAh, and 4800mAh. I want to know below questions:

1. Is it ok for me to replace my original 14.8v battery with a 11.1v battery? How would it affect my laptop?

2. Is it true that a battery with 4800mAh rating would give me more operational time than one with 4400mAh rating?

3. I know that a Li-ion battery does not suffer from the memory effect. Still, how long should I charge the new replacement battery for the first time (during the 3 repetitive conditioning cycles of charge and discharge) to ensure it’s longevity in the long run? I don’t wanna overcharge the battery but I’ve noticed even Li-ion battery manufacturer/distributor Web sites advising 4, 6, 8, 10 or 12 hours (funny how it’s always a even number).

4. During these first 3 cycles of conditioning, should I let the battery discharge fully until the laptop hibernates/shuts down or should I recharge as soon as I first see the battery low indication?

Above four question is my best concern problem for my DELL  Laptop battery,and I will ask DELL service center to know it.

My wife’s laptop doesn’t react to having an latop AC adapter plugged in, but it can still run off of battery.I charge her battery in my laptop and all is well, but that gets old quick.Any ideas as to what could be causing this?

 Is this a new laptop or an older one? After two and a half years, my laptop’s AC adapter went bad. There are stress points at various points on an adapter. Go to a local retailer w/ a decent return policy and buy a universal power adapter. They usually come with a transformer, an AC plug, and another cable that goes to the computer. It should come with a variety of plugs for various laptop brands.

 Buy one (I use a Targus adapter) which is capable of putting out an equal or greater power output as the one your wife has. It should say it on the adapter itself. I don’t remember how I determined my laptop’s power requirements. I think I took it from the battery’s voltage and amperage stats.

 Anyways, if this doesn’t work, then you can rule out the AC adapter and figure out what to do next. But changes are that your AC adapter will fail sooner than the laptop’s motherboard power plug header.

 I can’t believe I didn’t mention this before, but no, it is not an AC adapter issue. I’ve tried 3 different AC adapters, none of which work. I have taken apart the laptop and it does not have any visible issues. (no burst capacitors, no pins missing, no burnt traces, etc.)

 My wife is having to use the backup laptop which is a mac, and since the mac only talks to obscure japanese cameras, and not 2 year old american printers, she is eagerly awaiting a working PC laptop.

Any more tips? I’ll check for firmware updates tonight and post back?But I’m still having issues, but I’ve noticed that if I press down on the laptop AC Adapter where it connects to the laptop, then the laptop gets power from the adapter. (not the wire, but the hard plastic portion, so I’m guessing it is a short or something on the power recepticle thing).So I’m just going to save up and ship it off to HP and let them send me a working laptop, whether that is the original one or a refurb, as long as it works, I’ll be happy.

I’ve been running my HP Pavilion zd8000 exclusively off the laptop AC adapter for about 1.5 years now and just the other day the laptop no longer runs off the adapter.What happens is that it will charge the battery if the laptop is off, but as soon as I turn on the laptop the adapter shuts off (light goes out) and the laptops begins running off the battery.

I never bothered to try that, but then I really don’t care about the battery other than as a backup if the power goes out (which is meaningless since in that case the router and the cable modem go down since they aren’t on a UPS battery backup, hehe).I have yet to contact HP support, but sweet jebuz, I hope there isn’t anything wrong with the socket on the laptop.I had another laptop AC adapter handy but it was a 1.5amp and the “broken” one is 2.2amp so not compatable.

 If the AC adapter will charge the battery at all, I say it’s at least not dead. Maybe not acting right, but not dead.On the other hand, if the AC adapter turns off when you turn the lappy on and try to run it off AC power, it would seem that perhaps you have a partial malfunction at the actual plug receptacle on the laptop.

When I try to turn on my laptop without any battery but plugged in, it boots fine.. but windows does not start.. so is it ok to take out my laptop battery while the laptop is switched on (and windows loaded) so I will only use my laptop on the power supply?

 It should be fine to remove the battery whilst Windows is running, as long as there is a mains power supplyconnected. Whilst it is, I believe the battery is not used, but merely charged. It is only when the mains is disconnected, then the laptop battery is used.

 I was reading online, that it might take up a few charging cycles, although it’s not being used.. IDK, some people said it’s false.. other said it’s true.. my main concern is, as I already said in another thread.that if I leave my laptop overnight with the battery in place and the main supply disconnected it discharges the battery. so I want to unplug the battery.. but I have to plug it back in for windows to load.

 Well, I fixed it. When you remove the laptop battery it resets the BIOS (or something like that).. because I can overclock it from there, so in case I screw up something and it doesn’t boot.. I remove the battery, plug it in and it will reset everything(says it all in the BIOS, I have a dedicated section for overclocking).. So, what I think was happening is.. because there was no battery it resetted the BIOS settings and didn’t save them again (because I didn’t plug in the battery) so I pressed DEL, set the HDD as boot (DVD-RW Drive was 1st) saved, and then it booted up.

A day will come when your laptop battery will no longer charge and instead serve better as a paper weight. As you use your battery more often, the battery loses more and more capacity until it finally won’t accept a charge and goes flat. Replacing a battery is easy, but the new battery price could be so steep that it costs more than the laptop is worth. Buying a refurbished battery can drive the price down even lower, but what if you are super cheap? Well, we are going to cover this last option, which means tearing apart your old battery and fixing it yourself.

Teardown Process

Breaking the battery apart was probably the single most painful moment of this entire article. I had no documentation to work with, the plastic halves of the battery were glued together, and all I had was a mini snipper. I first started by peeling off the top sticker exposing the open framework with cells in view. After this I took my little snippers to the plastic, and cut away piece by incredibly small piece till the entire top was removed. I had black plastic bits flying everywhere; I think even into someone’s can of soda. The end result was a brutalized battery case that looks 100 percent safe for future use.

 Once all of the excess plastic was removed, I could get to the cells I would be replacing. All of these were glued in place, so prying them out with a screwdriver was the only option. As I slowly lifted each group form the plastic case without shorting any circuits, I took my clippers to the metal bridges to fully disconnect the batteries. During this time I also made special note of the wire leads off the charging circuit and where they connected for future use.

Finding the Correct Replacement Cells

Who would have thought finding something as simple as US18650BR batteries would be so hard? It actually took two of us about 30 minutes to find a site that sold equivalent batteries. We narrowed in on www.battery-replacement.org , as we found it mentioned on some odd website as a place to find batteries. Now the standard name for the battery size we were looking for was 1650, and we picked one at random since they had quite a few options to choose ..and I was too lazy to run the math on the correct cell capacity. With the cell selection locked in I ordered the batteries, and sat patiently until they would arrive.

Build Day

Once the new batteries arrived at the office, I got to work on prepping the batteries for installation. I verified battery orientation from the pictures of the old assembly, and started to solder together pairs of cells. I used some old wire to bridge together each group on the positive and negative side, and hooked the first battery group to the red power lead. Next step was soldering together the second group, attaching it back of the first group, and soldering both charging leads in place. Last was the third group soldered to the back of the second, and attaching the black lead to the rear of the battery group. The final result doesn’t instill much confidence of a non-firey demise, but it was finished. To add a layer of safety I placed some packing tape over the exposed battery groups, and mashed the “rebuilt” battery into the bottom of the laptop. To the surprise of all those around me, the battery did not ignite into a ball of flames, and actually started charging.

Performance

The Dell Inspiron 6000  laptop was not the pinnacle of mobile performance from the start, but with the old battery it was difficult to get more than 25 minutes of life before the laptop shutoff. Anything above that value with the rebuilt battery would be a mild success, so I crossed my fingers and hoped that an hour of smoke inhalation (soldering) wasn’t wasted. The results of the rebuilt battery ended up being roughly 47 minutes of battery life, and a Dell battery warning saying the battery had reached the end of its useful life. While the cells were fresh, the batteries charging circuit hard already reached the point of no return. No matter what we could do, it would never reach the charge levels of its prior brand new state.

Conclusion

With the labor involved in rebuilding the battery, and the $53 spent on parts, the DIY rebuilt Dell battery never got anywhere near the performance of a new battery. Although it was a fun process the money could have been better spent on a professionally refurbished battery or a brand new replacement  battery from www.battery-replacement.org . Even if the rebuilt battery did achieve results similar to those of a brand new module, I don’t think anyone in our office would have trusted that laptop to charge unwatched for any significant period of time. With brand new batteries exploding left and right, do you really trust something you rebuilt yourself?

Pros

• Tons of soldering smoke that freaked out coworkers
• People don’t mess with you after they see this in your hand

Cons

• Bringing this through airport security creates a stressful and unhappy situation

I want to use an laptop battery for my new laptop system,but i don’t  confirm that i can really use it in my new laptop.So i call the laptop battery service,he tell me some laptop system knowdage and  how can i do?

Li-Ion cells are permanently damaged when their charge drops below certain levels. If the voltage gets too low, the laptop battery will stop working and become unsafe to use. Therefore all systems powered by Li-Ion laptop batteries have a predefined threshold set to shut down at certain levels of discharge. As a result, Li-Ion laptop batteries are made to the exact specifications of the systems they are designed for, and vice-versa. This is where laptop batteries from another system or low-cost generic laptop batteries may not be compatible. If the thresholds of the system and laptop battery do not match, there is a risk of power cutting off at the wrong moment. This may lead to unsaved work being lost, data corruption, or irreversible laptop battery damage.

In addition, generic low-cost laptop batteries are not made with the high safety standards of official laptop batteries. Main-brand laptop batteries use only approved safety circuits in their laptop battery packs whereas there is no regulation of off-brand laptop battery production. This, as well as attempts by laptop manufacturers to ensure approved laptop batteries are used, is responsible for the higher cost of official laptop batteries. There have been reports of laptops rejecting generic laptop batteries (to avoid usage of potentially dangerous laptop batteries) without software changes (bypassing the security system). Some generic laptop batteries even fail to work altogether.

There are subtle differences in design, manufacture, and the operation of generic and official laptop batteries which may or may not cause problems for you. For every person that has had problems using generic laptop batteries, there is another who has had no problems whatsoever. You must decide if saving a little money on a replacement laptop battery is worth the potential risks.

I recently purchased a used Dell Inspiron 6000 Laptop, but the battery wouldn’t kep a charge. M friend has an Inspiron (model unknown), and has 2 back up batteries. He let me borrow one to see if it was the battery or the
laptop that wont charge. My laptop wont charge his battery. A warning screen comes up that says battery can’t be recognized. Is there a reason for this and a waqy ariund it. I can’t afford $200. for a new battery, Ijust spent all
I had to buy the laptop and get it running.

 My father tell me to contact Dell. There is nothing anyone can do for you here.If you “recently purchased a used Dell Inspiron 6000″ it is under warranty and it isresponsible for charging the battery.The battery itself has only a one year warranty.

My uncle has a Dell Inspiron 6000 battery, and his battery finally got to the point that it would only hold a charge long enough to more the power plug from outlet to outlet, 2 minutes. I bout a new one for $50+/- someplace.
But a 100% replacement model# for model#. 9 cell too. Not the 6 cell. It works great.

 Also try the reverse, if the other guy will allow you to, take your battery to his machine and see if it charges. If it does then the battery is good. Look at power packs or the laptop itself then. You can swap power packs too to try to eliminate the defective part. You are lucky if he has a 6000, as this makes troubleshooting a breeze.

A couple of weeks ago my laptop battery that came with the laptop started to have some problems. It would only charge up to 9%. A day or two ago it just completely died on me. I looked at the acer website looking for a new battery and I noticed that the version I have people have been saying that it dies about a year after you get it. this battery is buy from this wed site http://www.battery-replacement.org  . anyone have likely problem ?Its the 56 WHr 6-Cell Lithium-Ion acer Model# Aspire 3000,14.8v,440mah,Li-ion.

 There is another 9-Cell up that is a different part number of mine but there has been no reviews for it yet so I dont know if its good or not. Also its almost 300 dollars compared to the one i have now which is 150.So my problem right now is I have no idea what to do or which one to buy. I also really dont want to spend 300 bucks on a battery. I’m hopeing that there are other batteries out there that are cheaper and probably better then the one i have right now. So if anyone can help or give any ideas that would be really helpful

 The liability issue is having makers lock out non-manufacturer batteries. On top of that, a spam we clean off the forum is where spammers post web sites to promote them with a story not unlike yours.But here we know that battery liability issue and will refer you to the maker or companies like Duracell since you avoid the situation with a catastrophic failure and an unknown battery maker.

All new laptops come with AC adapters. Adapters are used for charging laptop batteries and also used to supply power directly. There are occasions which we require to buy an AC adapter. Most laptop users travel, for they travel to Europe or US they require AC adapters that take 100-240 voltage input and output 16 voltage or 19 voltage.Let us present 3 easy steps to pick the right laptop AC adapters.

• 1. Finding the right “tips” – Different laptops have different connectors. You need the right tip for your laptop. This is very simply to find. Basically, laptop AC adapters comprise of 2 ends. One end is male power outlet. You use this end to plug into wall power outlet. The other end is called “TIP” which you will plug this tip into the “DC IN” in your laptop. Your laptop won’t work on the wrong tip. You can only use the ” matching Tips”
• 2. Finding the right “output voltage” – Different laptops were designed to consume power varied by equipments such as CD-Rom, LCD size, CPU maker and CPU speed. You require to use the “matching voltage” . Only use the laptop AC adapters output the matching voltage of your laptops. You can easily locate your laptop voltage. Mostly, voltage is printed on your laptops. You also can check your laptop manual.
• 3. Find the right “input voltage” – for they users who will travel abroad especially to Europe and Asia. You would need laptop AC adapters that compatible with 220-240 voltage also. So it would be wise…and yes…you are!!…. Always look for AC adapters accept 100~240 voltages. 100~240 voltages AC adapters will go with you worldwide. You do not need to carry 2 adapters anymore!. That’s easy! You now know the basic knowledge to find your laptop AC adapters.

Above  is the best ways to choose the right laptop AC Adapter for your laptops.I think it is very convenient to choose the right laptop battery charger for your notebook battery.

my Ibm ThinkPad R40 battery suddenly stop working. it was working very well but one day i notice that it shows orange light instead of green. when i unpluge the AC it direct goes off directly. i connect Ac again and when i enter in the windows bettery showes 18% and it remain 18% after all i again unpluge AC again it goes off. but in windows it show 18% charged and charging but it does not working.I ask the saler what to do.

He tell me that it could be a malfunctioning battery? How old is the battery.may be you need a replacement battery?

I tell him that its two months old but its of China i just have one month warrenty. it was working perfectly if there was any problem it must show me before like low battery immediatly or any error caution but nothing.. it stuck to 18% and not working.

At fanally,he suggests me try another battery (buy or borrow, it’s up to you), preferably genuine IBM laptop battery and not generic.So i find the ibm thinkpad r40 laptop battery from www.battery-replacement.org  and the battery detail is below:
