Answers :

Hi there, Please remove the SMPS from there computer & check it in other computer. If its on then the problem happens in your motherboard power supply psrt. I suggest you remove the RAM & CPU from the mother board & clean it by soft cloth or paper & fix it back. After that try to power on. If no success then remove the SMPS and check. 80% chance is your SMPS damaged. Reamaning 20% chance in RAM/CPU/motherboard. Thanks & waiting for your feedback.

\015\012It sounds like you might be having a problem with your Notebooks motherboard.
\015\012
\015\012Question is there normally a certain time you have to wait until you are able to turn on your notebook again?
\015\012
\015\012Also after you are able to turn on your computer does it turn off on its own or does your computer stay on until you turn it off?
\015\012
\015\012Test what I would like you to do is remove the battery and unplug the AC power then hold in the power button for about 20 seconds. This will remove any charge on the motherboard. If the system comes on after this but the problem comes back then you have a short somewhere on the system.
