Display does not turn on when waking up from sleep, win10

[account_disabled]

Hi,

When the PC goes to sleep, the power light on the case starts to blink slowly, and the monitor shauts off. When I attempt to wake the PC up, the power light goes solid (and the CPU fan turns on), but the display does not show anything because there is no signal being received by the monitor. I believe that the system is actually 'awake', but since there is no display output, I cannot really tell and I cannot make any forward progress. Instead, I have to hard shut down the system.

I have the same problem when using the Intel integrated graphics, without the discrete GPU.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
