What if the motherboard doesn't have electricity?

The reason why the motherboard is not power and how to solve it:

Check whether the computer's power supply fan will turn up, whether the hard drive has self-test sound, whether the monitor is lit, if this time the computer displays "CMOS Load failure".

System prompts to press "F2" key to continue to boot, regardless of it, press "Del" to enter the BIOS setup.

Press the F2 key to allow the system to continue booting, if still unable to access Windows XP desktop, restart again.

Press the "Del" key to enter the BIOS settings, then do not need to enter the password, you can directly enter, it is obvious that the CMOS battery is out of power.

Need to buy a new battery into which, and then all the equipment on the boot, the computer can be launched smoothly.
