After opening up laptop and cleaning no display

Go to solution Solved by Sawa Takahashi,

It wouldn't hurt to make sure all components are seated properly and that no dust entered the connectors while they were removed.

The CMOS battery may or may not be dead but given that you can get one at the dollar store for next to nothing, just replace it by a new one.

At his point, it is possible that it is a RAM failure but it can also be many other things. Good job for checking all the cables btw.

Do you have a command for enabling an external display ? On many laptops it is toggled on and off with Fn+F5. It may be another key combination on your model.

Good luck !

Here i go again as in previous post i cleaned the laptop but after it powerd on and black screen

 

So laptop 2013 and when i cleaned i took out cmos battery, ram, ssd out and put em back in at finished

Every connector is secure i verified 3 times!

I press power button but the screen does't lit up and for 1 sec fan is working than i get no sound,no power to usb devices, the power button is lit

Could this be a ram failiure or a cmos battery beeing dead?
