Won't turn on and flashes a white screen

[SkippyDo0]

I haven't used it in a while and decided to bring it back out and I've charged it a bit..but when I try to turn it on it quickly flashes a white screen and makes some kind of quick static noise then goes back to a black screen..is this a fixable issue or is it the end of my laptops life?

Hi @SkippyDo0,

Welcome to the HP Support Community. 

I'd like to help!

Try charging the laptop completely and make sure that any cables are loose. 

Also, try the steps mentioned below

POWER DRAIN:

Please disconnect all the devices and cables connected to your computer including the power cable and then press and hold the power button for about 20 seconds and connect the power cable back again and try to power on the computer.

CBR:

Press windows key and then followed by the key "B" this time and then the power button for around 3-4 seconds, then release the power button and continue to hold windows+B for 3-4 seconds more.

Hope this helps! Keep me posted for further assistance.
