Laptop won't boot after opening it

[nicholasvilchesb]

Hello,i've just opened my hp 14 g005la to change my cpu and gpu's thermal grease, i've triple checked everything's in it's place and i don't see anything wrong,and now it just turns on with my CAPS key blinking and my wireless key off,i'm confused on what's happening because i hear the fan and other things working but it just isn't booting at all.

So it 'is' actually on, just the display isn't. Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
