laptop screen wont appear after closing lid

[Guerlan]

Whenever I close the lid of the notebook, when I open again, I see the keyboard light lightning up but the screen never lights and I have to reboot.

Is there a fix for it?

Guerlan:

It sounds like suspend/resume isn't working correctly on your laptop
under Qubes. Does the same thing happen when you click suspend from the
logout menu?

As a workaround, open the Xfce Power Manager (Start -> System Tools ->
Power Manager) and change the lid switch to "do nothing." This way it
won't go into suspend when you close the lid, but it'll at least turn
off the screen.

Something else to try: download Fedora 30 and boot into a live CD/USB,
and try suspend/resume (by closing the lid) from there, and see if the
screen comes back on. If it does, it probably means Qubes' dom0 (F25) is
too old for your hardware.

Also it would help to know the make and model of your laptop. Ideally,
you can submit an HCL report: https://www.qubes-os.org/doc/hcl/

I did the HCL report and sent.

I tried the manual sleep and it wont work, the same thing happens as when I close the lid: the keyboard goes off and the screen goes blank and nothing returns when I open. I tried pressing the power button but also didn't work.

The workaround isn't good for me because my notebook has very limited battery, so I need for it to sleep while closed.

I tried Fedora 30 and sleep worked perfectly. I just closed the lid and reopened and it worked.

Can't say for sure, but probably F25 is simply too old, and lacks the
necessary firmware drivers, or whatever, for your laptop. In other
words, the hardware is too new for the software.

The good news is you're not alone. I ran into this exact issue a couple
of months ago, and two other users have posted here about the same
problem since then. The bad news is no one has found a fix, as far as I
know.

Here are links to those conversations. See if it sounds like what you're
experiencing. There are some troubleshooting tips mentioned there that
you can try also. Let us know what you find out.
