To perform this PC Trick you will need the following tool:
1). #1 or #2 Phillips-head screwdriver
2).T-15 TORX driver
3).1/4" hex nutdriver.
4).Needle-nosed pliers if you are working with jumpers
A small flashlight or headlamp
With tools at hand, perform the following steps for this computer trick:
1).Turn the PC off (this means a total shutdown, not merely standby or hibernate mode) and disconnect the AC power cord.
2).Remove the cover from your system (this step may require tools, undoing a thumbscrew, or flipping a latch or two).
3).Refer to the user manual for the motherboard to find out how to "reset CMOS" memory. You may also find a label for specific jumper or switch settings marked on the system board.
4).Change the switch setting or jumper position to a specific position or remove the jumper entirely as prescribed in the manual to clear or reset the CMOS memory.
5).Wait 20-30 seconds for the memory to clear out from lack of power. After 20-30 seconds put the switch or jumper the way it was before for normal use.
6). Reconnect the power cord and start up the system to see if the settings have changed to defaults.
7).Shut the PC down, disconnect the power cord, replace the cover, reconnect the power, and power up the PC.
8). Enter the BIOS setup program to configure the system as needed. This may include setting the date and time, selecting disk drive parameters, and selecting which devices the system uses to boot up with first.
9). If your system does not have a "reset CMOS" jumper or switch , the only option is to locate and remove the coin-style battery cell (or on some very old PCs, the battery pack), as shown in , that provides the power to the CMOS memory.
