Laptop Motherboard and CPU work

Try Clearing out CMOS – This is incredibly simple. All you have to do is find out from the motherboard manual where the CMOS jumper is. Make sure the system has no source of power which means that the power supply is unplugged and the battery is removed. Then move the CMOS jumper over the pins that clear it. After a few minutes, put the jumper back, plug the battery and power back in and try switching on the laptop. If that doesn’t work continue below.

Now, remove the system from the case, place it on a non-conductive surface and disconnect all components from the motherboard to check if some peripheral is preventing up the possibility of the motherboard shorting onto the case somehow.

To do a quick elimination (only if the system is completely failing to give any power at all), find where the power button connects and short those two pins for a moment with anything conductive that you have on hand. If the system spins up, you need a new power button. If the system fails to power up outside the case you need to perform the following analysis.
