Acer Aspire 4535G Problem
 

I got Acer Aspire 4535G laptop from singapore. Though it was all smooth going, but suddenly dont know what happen. when i m keeping the laptop on charge it works like charm. as soon as i remove it from power the battery doesnt last long for more than 2 mins. its gets off. i charged my battery completely still its lasting only for 2 mins. While charging it starts from 0% and it takes 20 Mins and shows 100% charged. but still it cannot last for more than 2 mins when i unplug from the charger. can any one help me on this. where is the problem arise in it

Sounds like a bad battery. Do you have a spare, or a friend with the same model you can switch batteries with to test this out?

There's also this thread about the Acer Aspire One battery that a BIOS update seems to fix. http://www.flyertalk.com/forum/trave...ne-6-cell.html
Have you checked the Acer web site to see if there's an updated BIOS for your model?
