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.
Re: My laptop wants start up on AC power supply only
Many thanks for your opinion. But it is still strange for me that my Asus which battery lasts couple of minutes only can start up on this battery without problem. I have no possibility to try my battery on another Acer Aspire.
