Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
I am sorry to know that you are facing problem with your computer. Let me know the make and model of the computer which is not powering on.
how old is the computer?
Please take the battery out and unplug the power cord as well from the laptopleave it turned off for 1 mins and then push hold the power button for 30 seconds without connecting the battery or the ac adapter.Connect just the battery and turn on the laptop and see if you get any display on the screen, if not then try removing the battery and connect just the acadapter and turn on. Please let me know the status.
We will diagnose the problem and in case of hardware failure i can tell you what part has faulted but cannot make a bad part work again till its repaired or replaced. I hope you understand.
Do you hear any beep code when you power on the computer?
unplug the ac adapter and remove the battery look for the memory bay and open it remove the ream and let me know once that is done.
look at the bottom panel you will see a screw securing the memory bay open the screw remove the cover you will see the memory
