P51 doesn't wake up from sleep

Hi 

 

    I bought a new p51 last week and am experiencing this issue from time to time. When I don't work on the laptop, I just close the lid. After some time, I see that the red led light on the lid goes blinking on slow pace - that tells me the machine has gone into sleep mode. Now, when I come back to the machine later, usually I see either the red led is still blinking or completely gone off.  I open the lid, the machine wakes up and I cannot work, I see black screen.

    Problem exists on Windows 10 and Fedora 27, so this problem is related with BIOS. One more thing, this problem is not present on battery only when laptop is connected to AC adapter.

 

BIOS: 1.20

The problem was found after upgrade BIOS to 1.44 so the problem is related with BIOS. After replacing the motherboard (BIOS problem not exists) after upgrade to 1.44 problem back to alive Smiley Happy 

Service replace 3 motherboards so I'll stick to old BIOS Smiley Happy
