hi, im having a problem with my laptop, about a week ago,the date and time of the system changed to 9999, all of my programs went crazy, i can change it back to normal but it keeps changing every time it goes into screensaver, hibernation, or i restart the pc. im runing windows vista and tech suport from dell told me that it could be something called mother card, i really dont know anything about computers so i was hoping that anyone could help me figure this out, reading other similar posts, i checked the bios time and it is running very fast and changes every time i restart.
thanks

If settings like Time and Date are changing especially when the PC is turned off suspect the CMOS Battery as the culprit.

It is normally a small flat round battery located on the motherboard that often has a little clip or lip to hold it in. Follow normal precautions like PC off etc before mucking around inside.

Cheers.

instructions on how to access this battery in your computer documentation. If you have nothing from the vendor on your computer or in print to help you with this, go to the manufacturer's website and search for a manual or page in the Support area for your exact model of computer. Searching for the model number is what will help here.

The battery is sometimes accessible through a little access panel on the back of the laptop.

Bonus: The motherboard is the electronics board in the system to which the processor and everything else is connected.
