Hello,

I have a Lenovo P340 with Windows 10. I was trying to make a shortcut to put my pc in sleep mode. So I enter the following command prompt: "powercfg /hibernate off" then I made a .bat file with the following line "%windir%\System32\rundll32.exe powrprof.dll,SetSuspendState 0,1,0<br>" I don't recall exactly when all started, but while doing this my pc went on black screen, but still functioning. Inspite this, the music playing on the back was still on, and I could rise and lower the volume with my keyboard. If I power the PC off and then on. The PC initialize and after the Lenovo logo with the charging cycle, it goes again to black screen. I can enter to BIOS config. With another PC I loaded bootable USB with Windows 10, initialize from the USB to delete the SSD drive and install the new Windows, no problem with that. After the new installation I could use the PC with no problem at all BUT 3 minutes after I connect to internet, the charging mouse icon appears and after one minute the screen goes off like when all the problem started. I tryed once the utility "Startup Repair", the first time didn't work, after trying different things it worked, and on desktop a pop up sayed "We removed some recently installed updates to recover your device from a startup failure.". Now I can enter the PC but the sleep mode option doesn't exist. I search and try different ways to enable it but none of them worked. (1] Restore or Enable missing Sleep option, 2] Restore Power Plans with command prompt, 3] Edit Group Policy, 4] Update Windows and Drivers).

The commnad "powercfg /availablesleepstates" gives the following output:
The following sleep states are available on this system:
Hibernate
Fast Startup

The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.
An internel system component has disabled this standby state.
Graphics.
Standby (S2)
The system firmware does not support this standby state.
An internel system component has disabled this standby state.
Graphics.
Standby (S3)
An internel system component has disabled this standby state.
Graphics.
Standby (S0 Low Power Idle)
The system firmware does not support this standby state.
Hybrid Sleep
Standby (S3) is not available.

I updated the BIOS with the Lenovo "system update". Erased the whole SSD to install a new Windows, but that doesn't change anything. Also I tryed reprogramming the BIOS chip with a programmer but ofcourse that didn't change anything. It seems that I corrupted something really deep and can't figure out how to solve it.

BIOS.Name="M2WKT46K"

Any help is welcome!
