Hello Lorawil, and welcome to Seven Forums.

Usually you could turn off the PC, unplug the PC, remove the battery on laptops, remove the CMOS battery on the motherboard, wait about five minutes or so before putting the CMOS battery back, and see.
Do exactly what Brink suggested . If you don't know how to remove the CMOS battery pack , give me your computer model number so I can find the guide for you and assist you from there.
