Power Switch in computers

When you look out for computer problems, one of the simple problems could be your power switch.

Problem: 

Computer doesn't start when you press the power switch. Computer does give no response when you switch it for multiple times. 

Reason: 

It should be either due to any fault in your SMPS (Switched Mode Power Supply)) or due to the connection problem in the power switch. 

Some of the computer does have an indicator in the motherboard. If that light blinks, when you turn on the power supply (not the power switch in CPU), it indicates that power is coming to CPU and your SMPS is just working fine. But if the computer doesn't start after switching the power switch, then there is a problem.

Solution:

The problem with power switch can be solved, just be reconnecting it again. Still if doesn't work, carefully take down that connection from the mother board and change it with the new one bought from your nearby Electrical store. 

To reconnect the switch you can take it out by slowly removing the front panel of CPU as follows,

   

You can trace the wire connection to motherboard and reconnect it with itself or new one. But you will learn one thing about, How the power switch works in a Computer.
