Acer Power/Charging/Battery problem

Scotland · 02-19-2007, 05:59 AM

Hi,

I hope you can help.

My Acer laptop that I've had for about 2 years is now is no longer charging properly.

It will not run of the mains at all. I tried taking the battery off but it still won't work - it will power up for about 3-4 seconds then just shut down.

Bizzarely, it charges the battery so at least I can use it, but as its not got an M processor the battery life is about 45 minutes!

Sometimes it won't charge the battery at all (It will flash orange instead of just charging) and I have to switch it on and off a few times just to get it charging.

If it is charging and I switch it on, it will stop charging and go straight to battery power.

I took it to my local PC super store and they seemed baffled saying they'd never heard of such an issue!!...

Can anyone help?

I've tried buying a new charger which made no difference at all.

Its a ACER TM2702WLMI.

Thanks,
Gordon.

Is there any diag lights on the battery or the ext power supply *Its good news if you get 2 years out of a battery* I see you say it only sometimes charges Do do you move the unit around a lot? Gharges out of a Known good power supply. Is there there anything else that happened instalation or hardware changes?
interogation over

Do you use this for buisness or personal use?

Check Power and Docking profiles?

How would you feel doing a system teardown?

Hi Gordon,

This is strange. I have an idea that may be a longshot, but it could work. Go into the BIOS, and see if there is an Intel SpeedStep (EISS) control, and if there is, enable it. Also, if you plug the laptop in while it is running off battery, does it shut down?

Hi,

Thanks for the reply.

No, if I plug it in while its running off the battery it will not shut down providing their is enough battery power left. However, it won't charge. It only charges if the system is off.

How do I access the BIOS and enable the EISS?

Thanks again,
Gordon.
