I have a Acer Aspire 1690 laptop.
When the battery is plugged in the laptop is running really slow. Also the on board mouse & keyboard is either not responding or is really slow. Bad lag.
I can use a USB keyboard & mouse no problems.
I've found if i remove the battery the on board mouse & keyboard work fine and the slowness is also gone.
I'm updated the bios still no help.
Upgraded all windows updates & service packs.
Removed the Acer management applications. Haven't tried reinstalling them yet.
The battery is stuffed only get max 10minutes of life out of it. Not sure if this is the problem or not.
I've never seen this sort of problem before, so i'm reluctant to purchase a new battery just in case it doesn't fix it.
Anyone got any ideas?
Thanks in advance.
