My computer's battery is dead but is still installed, so my pc runs completely on electrical power. However, whenever I boot, the Toshiba Setup Utility page displays, and I have to go through a routine pressing of 'enter', 'ESC' and 'enter'. This just feels wrong. How do I overcome this? I tried pressing F12 repeatedly upon startup; it worked for that time, but it doesn't fix the problem completely. Thanks for your help.
