Clearing Your PC’s CMOS (BIOS) Settings
Clearing Your PC’s CMOS (BIOS) Settings
CMOS is a chip that keeps a record of installed components when your PC is turned
off. Clearing CMOS settings may help you resolve some common problems. For
example:
• when you need to clear passwords to have full access to your PC’s BIOS Setup
• when your PC cannot detect an expansion card or other device
• when you are having problems booting the PC.
You can clear CMOS settings:
• by using your PC’s BIOS Setup program
• by opening your PC and clearing CMOS manually.

Notes
Operating temperature and humidity ranges may vary depending on the mass storage
devices installed. High humidity levels can cause improper operation of disk drives. Low
humidity ranges can aggravate static electricity problems and cause excessive wear of the
disk surface.
The power consumption and acoustics figures given in the tables above are valid for the
standard configuration as shipped.
When the computer is turned off with the power button on the front panel, the power
consumption falls below 3W, but it is not zero. The special on/off method used by these
computers considerably extends the lifetime of the power supply. To reach zero power
consumption in “off” mode, either unplug the power outlet or use a power block with a
switch.
