I need you help guys. I bought a HP Envy x360 4 months ago and it does not start anymore.
Well it starts, as I can hear the fan and can see the keyboard lighting up for a couple a seconds, but nothing more. The screen stays black.
I was thinking about doing a hard reset on it but I cannot find how to do so (I tried to push the power button for 1 minute, without success). Do you think it will help? If yes, do you know how to do it?
If you just bought it, it should be under warranty. Unless you bought it used. If purchased new, then contact the manufacturer about getting it repaired.
Now if it isn't new, and not under warranty, then try the following...
Turn the laptop off (not sleep or hibernate but off).
Connect an external monitor to the laptop.
Turn on the external monitor.
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.
You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
