Question HP Chromebook will not power on ?

Mar 22, 2023
So 3 days ago my Chromebook was working flawlessly, then earlier in the day and then after i closed it and then opened it again it a few minutes later it just wouldn't power on at all.

I have made sure its fully charged and it is so it can't be because the battery is dead even the light on the side is flashing white.
I have followed all tutorials and they say to hold down power button or refresh + power button or even esc + refresh + power button but nothing works, the screen is still black and nothing is appearing on the screen. My brightness is also not down to minimum for sure so it must be something else :(

Only thing I haven't tried is opening it up so what can I do to fix this issue? If anyone can help it will GREATLY be appreciated!!
