I bought a new HP laptop a week ago that came preloaded with Windows Vista Home Premium. I also use wireless mouse and keyboard with this. The problem am facing is when I start my laptop powered with AC, my screen saver wont work, neither gets activated. And if I boot the system with just powered by battery, everything seems to be working fine. Furthermore I have set the balance mode "Turn off Display" at 2 mins and screensaver for 5 mins. Any idea what could be the cause for this strange problem and how can get rid of it? Many thanks.
