Windows 7 goes wild when running on battery

[anish_sha]

I have a HP pavillion dv6-1215ee laptop, it came with Windows Vista Home premium , i have installed windows 7 Ultimate and also Ubuntu Linux, now the issue is the windows 7 works well and fine when running on A/C power , but when the A/c power is removed , sometimes it works fine for say 10-15 minutes and suddenly it will act weird , too sluggish , clicks take minutes to respond... but when i run Ubuntu , it works very fine, no issues at all, i have all the updates installed on windows 7 , still the issues persists... any solution friends...???

The processor may be down clocked to save battery. All laptops have the option of changing settings while on battery to conserve it. There should be some system utilities by hp or right click the power meter and look through the options to change the settings

It's the laptop trying to save power. Go to power settings and choose a balanced setting.
