Acer Aspire Battery Problem

juggym · 10-27-2009, 07:54 AM

Hi.
I have an Acer Aspire 5050, running on XP.
AMD Turion 64 Mobile
Technology MK-38
2.20 GHz, 1.93GB of RAM
Physical Address Extension

Microsoft Windows XP Professional
Version 2002
Service Pack 3

My laptop kept freezing on startup, instantly. The mouse wouldn't move and the CPU usage went off the scales. After much research, I realised that my battery was to blame. When I unplugged the battery and only used the power cable, then the computer wouldn't freeze. So I decided to buy a new battery off eBay.
The battery has arrived and I now have another problem.
If I use ONLY BATTERY - laptop turns itself off instantly. Soon as the black windows logo appears on startup, the laptop turns off.
If I use ONLY POWER CABLE - laptop boots up perfectly.
If I use BATTERY AND POWER CABLE - laptop boots up perfectly and batter LED is flashing.

The battery has been charged fully overnight.
I thought that maybe the new battery I bought might be dead.
But, if I press f2 during startup (this is with ONLY BATTERY) and the bios screen appears, the laptop stays powered for a long time (obviously this is useless for me because I can't do anything with bios settings!).
However, if I don't press anything on startup, then soon as it changes to the black screen with Windows logo, it turns off immediately.
I'm thinking that maybe Windows is making the laptop trip off.

If I startup the laptop with BATTERY AND POWER CABLE, it works fine. But when I take out the power cable, after 5 seconds, the laptop turns off. Not shut down, immediately turns off!

I have installed Acer's Power Management software. Still no change.
I have bought the correct battery. It is the same voltage.

Also, if I click the battery icon on the taskbar, it says 0% battery. So I don't think Windows recognizes the battery.

Anyone any ideas??? This is really annoying me.

So, even with a new battery its not working?

After talking with a couple of my colleagues at work, we have come down to one conclusion. If the battery (the new one) is not holding a charg AND it is compatible with your motherboard, then the issue is the connectors from the battery to the motherboard. Take a look at both the battery connection and the connection to the motherboard.

So, if it is under warranty, check out and see what it would take to get it replaced. If not, a new motherboard might be next in line to be ordered.

How do I know if the battery is compatible with my motherboard?
I am pretty sure it is. Right now, I am on the laptop. The battery is in and the power cable is in. In the system tray, there is a icon with a battery and plug. If I take out the battery now, the icon changes to just a plug. So the laptop is recognising that the battery is there or not.

It just won't stay on when only powered by the battery.

It can't be a dead battery. It was brand new sealed.
