My girlfriend has just bought a new Acer laptop (Aspire 3680). It works fine normally, but when on battery power, it is incredibly slow. Simple things like launching an application takes a crazy amount of time like 10 minutes. The obvious answer appears that it's faulty and should be returned, but I thought I'd post here and see if anyone has any insight on the problem. Thanks guys.

I do know some laptops underclock when on battery. I know i have mine set to go to 800MHz. Why don't you get CPUz(easy find on google) and post what type of processor she has and what speed it's running at both on and off A/C.

yeah thats definately normal behaviour for the 3680 machines, in fact only the older acer units dont slow down when you switch over to battery; you can adjust the speed of the unit by changing the power profiles in the acer epower management software.
