Eventually my pc would shut off with the battery installed, not charging. I had to remove the battery to use the laptop. I thought it was my charger (it was literally falling apart, and I had to find another tip since the original broke. I spliced it into the charger, but it would still not charge. About a week ago, I finally got a new battery, popped it into the laptop...it still would not charge. I then ordered a new charger, which arrived today. I promptly plugged it in, and I was saddened that the battery charge light was still not going. I did some research on the net ( loose solder connection where the charger plugs into the laptop) etc...still nothing. then...I wondered.....the connectors on the battery AND the laptop are copper.....well..copper corrodes VERY easy. I took a sharp knife and scraped the copper leeds on the laptop where the battery makes contact, makeing sure I scraped every one. I popped the battery back in...and low and behold...the battery started to charge!!!!! I am leaving the pc off and plugged in overnight as I type this giving the new battery a full charge. Tomorrow I'll put the old battery in and do the same. Now...all I need to do is figure out how to tighten the hinges.

The problem is to find some schema/spects of my motherboard and the test points. So, I guess, with a multimeter/voltimeter I can figure out who to blame. Thanks anyway.

First, Thank you for answered my question. I turned the power off, turned off the windows (and ubuntu) alerts when the battery is low to make sure that it goes to 0%, charged back (ubuntu shows that it's 100% full and the designed energy that it can hold is the same (a little ABOVE) of the normal. So, I tested it again: got to work and took off the battery from the laptop. I've put it back and... 100% full. Now, after some couple of hours with it completely sure that linux is turned off (no leds on, no device attached to any USB ports, etc), the battery is at 97%. Changed the place of it, ambient temperature is ok (checked the manual), so, I'm really lost. Anyway, if you want/need more information to make some kind of "debug" of my machine I can send you some pics of the main battery place and the battery itself. If you don't have time, I'll understand, your site is very busy. Thank you again. Hi! First, Thank you for answered my question.

Hello, may you can help me to figure out what is happening to my laptop battery. Before you lose interest in this message, I hope you read a bit more about my issue. Here is the thing: when I turn off my laptop (trademark DATEN, AMD 64bits dual core athlon x2, 2GB RAM, etc.) and turn it on after, say, some four or five hours, my battery is only 90% to 95% charged.

The question is: is any part/piece of a laptop that can be running even when I turn the laptop off? It’s like some part, say, the wireless card still sucking my battery life or another part, I don’t know where more to go to solve it. I’m a coder/programmer and I never saw this behaviour before. If you wish to help me out, I can get more information from my Linux or Win32 OS to send it to you. What I’m sure is that the battery is ok and my Ubuntu says that the battery is ok, all cells ok, and it charge full! Hope my english was enough to you to understand me. Thank you in advance.

There battery was dead so I bought a replacement off of ebay for about $35. The battery works fine and charges fine, but when it reaches 100, “sometimes” the laptop starts using the battery and drops the power adpater and will sometimes flip back and fourth between the battery and the power.

Does it happen only when battery charge reaches 100%?

I thought at first I may have a bad dc jack that was shorting or something, but that doesn’t seem to be the case because the laptop runs fine on ext power.

Here’s what you can try. Turn off the laptop, remove the battery and start the laptop from AC power.
Now wiggle the power plug inside the jack. If the laptop shuts down, it’s either bad jack or there is a short inside the power cord. Take a look at this post: Testing jack and power adapter.
