G460 does Not Wake after Sleep

[ Edited ]

I have a G460 with win 7 ultimate installed, whenever it goes to sleep mode I can't wake it and the only thing I can do is to hold power button to turn the device off and then turn it on again.

 

I did read every single thread related to this issue in this forum, and I did following things which does not solve my problem

 

1- I installed latest Bios firmware (V. 32)

2-I Installed latest graphic driver (285.62)

3- I disabled every "Allow the computer to turn off this devise to save power" in device manager, one-by-one to test which one will solve the problem, but no luck

4- I tried to reset Hibernate config using Powercfg -h off / on command line

5- I did downgrade BIOS firmware to v.25 but it didn't solve the problem

 

 

I did run powercfg -energy and did see the following error which I think is the main reason to what's happening to my device:

"Platform Power Management Capabilities:ACPI_PSD Failed Validation" in three different Index from 0 to 3 !! I couldn't find a way to deal with this.

 

I don't know any other way, is there anything remained to test ?

 

EDIT: I forgot to say I did re-installed Lenovo Power Management, But it doesn't helped me either.

Re: G460 does Not Wake after Sleep

Actually the problem is not that I don't know how to wake up a computer. By the way thx for the reply, I turned off hybrid mode for sleeping and it didn't help me.
I'm still looking for solution.

Re: G460 does Not Wake after Sleep

could be driver issue.
check if the issue persists on safe mode.

Re: G460 does Not Wake after Sleep

There is no sleep mode in safe mode
I think the important thing is why ACPI keep failing after BIOS update which should not happened any more.

Closing the lid has been set to hibernation and it is working properly.
