The method of clearly CMOS discharge has those

first, the system can be started, you can enter the CMOS, and did not set the power-on password, you can soft erase the CMOS, and restore to the default settings.

(1) Enter the CMOS settings, and transfer to the original default settings

Boot Press del, enter CMOS settings, in the CMOS Settings main menu, select Load Fail-Safe Defaults (load failsafe default) Use this menu to load factory defaults as a stable system use

or load optimized Defaults (load high performance defaults) Use this menu to load the best performance but may affect the stability of the default values.

Some motherboards have only load Defaults. is to restore the factory settings.

After the transfer is complete, press "F10" or select Save & Exit Setup (exit after saving) on the main menu and reboot.

(2) Use Debug to clear CMOS

Debug must run in DOS environment; If installed 98 of the machine, after the boot press F8 key, enter the selection settings interface, select 6 items, you can enter the DOS; If the installation is 2000 or XP, because it does not support DOS, you need to use a DOS boot disk, and the debug copy to the boot disk transport

The specific actions are as follows:

C:>debug

―o 70 10

―o 71 01

―q

　　Two. When overclocking does not boot up or enter the system or previously in the CMSO setting, set the security option to system, which can be used to discharge the CMOS.

(1) Use CMOS to clear jumper

Turn off the power, open the chassis, and locate the CMOS removal jumper on the motherboard, which is typically a three-pin jumper, marked with a clear CMOS logo next to the motherboard BIOS chip or battery.

Normally, the jumper is in the position of 1-2 (save), we just unplug the jumper, short to 2-3, slightly stop recovery to 1-2,cmos that is clear. At this point in the CMOS data is empty, in the subsequent boot, the system will be prompted CMOS data errors, and so on, prompted by F1 into the CMOS settings, at this time, we enter the CMOS settings, after the default settings, save the reboot can be.

(2) Remove CMOS setup with power off method

If this jumper is not on the motherboard or is not found. We can easily use the power off method to clear the CMOS

First on the motherboard to find the CMOS battery, remove the battery, and then with a metal conductor, short connection to the motherboard battery seat in the positive and negative, with a short circuit, quickly release the corresponding capacitance of the storage power, and achieve the purpose of eliminating the CMOS.

Short to the positive and negative generally 1 minutes or so, you can clear the CMOS, and then the battery correctly into the battery seat, reboot can be.
