My laptop didn't power on, but I remove keyboard it power on

My laptop didn't power on. But if I remove the keyboard, it will power on by using the master switch(pinhole switch). After that I connect the keyboard it will suddenly power off without any notification. Please help me with your knowledge.

Something must be shorted on your keyboard causes the system to switch as a safety mechanism.

Do you have photos of the keyboard and/or the keyboard connector?

Did your keyboard suffer liquid damage?

I agree with @honakrisi, also do you happen to have another keyboard on hand to test with. Does the computer blue screen? What comes up in device manager?

@honakrisi I'm sure, it didn't suffer any liquid damage.

@Nick p I try to replace the keyboard, but it won't work.

Thanks for your comments...

Hi @jbraja

Check that the Power On button is not stuck down in the operated position.

The power button is part of the keyboard assembly and if it "appears" to be permanently operated the laptop won't turn on. Disconnecting the keyboard, disconnects the power button.

If it seems to be OK you may have to replace the keyboard.

Here's the hardware maintenance manual for the laptop. Go to p.34 to see how to remove/replace the keyboard.

Here's a link to the parts for the laptop. Click on Select Commodity > Keyboards Internals (19) to find the part numbers for all the keyboards available for the model. Usually the part number can be found somewhere on the underside of the keyboard if you wish to verify that you're getting the same one.

Search online using the part number only to find suppliers that suit you best.
