Hi,

The battery for my notebook recently died. We went on vacation, and when we got back, the battery simply wouldn't charge. It would stay at around 20%, and read charging, but when the AC power is unplugged, the notebook would instantly shut down. We left the notebook shut down when we were on vacation, and unplugged, so there should be no problems. I have tried some simple troubleshooting tricks, but I still can't get any charge into the battery.

The batter model is ASUS Li-Ion Battery Pack AL31-1005. http://www.amazon.co...y/dp/B002TBAFAI

The notebook is the Asus Eee PC 1005 http://www.asus.com/...tksJTDENqfsnuyf

The warranty is expired, unfortanatley, as battery warranties are only 6 months and we've had this notebook for about an year.

If anyone knows a bit about batteries, help would be appreciated.

Thanks in advance,

MLN

Try cleaning the battery's terminals.

Another issue with batteries is the "memory effect", though I'm not sure if this'll help since yours won't run the laptop at all. Boot into Windows and let it run long enough to shutdown. Then boot, go into the BIOS, and leave it there until it shuts down (Windows'll shut it down at 5%, the BIOS won't but it consumes very little power so draining takes a while). Then plug it in and let it fully charge. See this: http://www.pcworld.c...op_battery.html

This sounds like the battery may have been drained too far. With LiIon/LiPol batteries, you have to maintain a minimum voltage per cell to prevent abnormal breakdown.

Removing and reinstalling the ACPI driver might work. You'll find instructions at Laptop Not Charging.

If that doesn't work, you can try draining the battery all the way and then recharging it. As a general rule, draining a lithium ion battery is a bad idea--it shortens the life of the battery. But it can also shock a seemingly-dead battery back to life. The way to do this is to run Windows with the AC power unplugged until Windows automatically hibernates. Then you reboot the computer into the BIOS setup screen, and leave it there, unplugged, until it dies.

Thanks for all the replies guys,

I've heard of that draining trick, and I'll try that and get you the results ASAP. I don't think we've drained the battery too far, because for normal uses we usually just plug in the AC power and take out the battery. When carrying the notebook around, the battery would be used, but not fully drained. It's just odd how we came back from vacation and found the battery dead.

Lincoln, can't believe I haven't tried reinstalling drivers yet. I'll try that too

Thanks for all the help. I'll come back with the results when I get them.

Ok, unfortunately...the battery appears to be dead. I've re-installed drivers, but that doesn't do anything. Also, it is impossible to "drain" the battery because it literally shows 0%, charging. In fact, it doesn't even show the battery indicator in the notification area!!

I guess it looks like this battery is dead. If there are any other ideas, it would be appreciated, but otherwise, thanks for your help.

They do die. Yours is a little early. I would simply replace the battery. I will say most of my HP notebook batteries last about three years. The last time though, I went with third party batteries via Amazon. $60 vs $150 OEM on one and the other HP no longer even stocked.

If anybody has a need for a good HP dv9000/9500/9700 extended run battey, let my know. About 6 months after purchasing this battery, my dv9500 died. My new laptop of course uses a different battery.

Yeah, just got one off Amazon for $50 plus $10 shipping. Waiting for it to arrive, it is a six-cell unlike my previous three-cell.

Thanks a bunch,
