BIOS changes have not taken effect.
It is possible that the changes were not saved before exiting the setup
utility. Go into the BIOS setup utility and make the changes again,
save them, and exit the utility.
All system boards use a battery to maintain system configuration
information. If the battery fails to maintain this information (for
example, if the date is incorrect), you might need to replace it with an
identically rated battery from the same manufacturer. Check your
user’s guide to see if you battery is user replaceable. If not, call the
NECC Technical Support Center for service.
Before replacing the battery, print out or note
your BIOS setup configuration settings.

How to Clean the Mouse
Under normal conditions, your mouse has a self-cleaning mechanism that
prevents a buildup of dust or lint around the mouse ball and tracking
mechanism. Periodically, however, you might need to clean the mouse
ball.
Use these steps to clean your mouse:
1.
Power off your computer and any peripherals attached to it.
2.
Invert the mouse. Locate the mouse ball cover.
3.
Rotate the ball cover counterclockwise and remove the cover.
4.
Turn the mouse over so that the cover and ball fall into your palm.
