My laptop wants start up on AC power supply only

[mmatic123]

Hi all. This is my first post on the forum.

I have 3 years old laptop Acer Aspire 5920G and it can start up on AC power suplly connected only. It does not want to start up on battery mode. As soon as I start up laptop with AC power supply connected I can disconnect power supply and my laptop runs fine for more than hour and half on battery mode. When I chose to restart or hibernate it can not turns on again on battery mode. It looks like I choose to shut down. I have another 5 years Asus laptop which battery lasts for 3 minutes only but it can starts up normally on battery mode.

My operating system is Win 7 32-bit.

Any help!!!

Could be your battery does not have enough power to boot it up. You could get a new battery.

You can also download this freeware app called BatteryCare that accurately monitors the laptop battery performance of your system and provides useful information such as total capacity, voltage, CPU temperature, and the manufacturer's info. This may help you get insight into whether it's a battery or something else.
