All was fine until a few days ago when Windows auto updated something and since the PC - a new Lenovo - will not auto sleep . I opted for premium support and my wife ( it's a made for Japan PC ) has called twice inc. today but the damn thing still won't auto sleep . Just wondering of anyone here has had the same problem and if there is a fix . I'm a PC dummy so bear with me my friends .
“You just need to reestablish the setting.
Control Panel /
Power Options /
“Change when computer sleeps”..
Tried that when we first called Lenovo support - didn’t help .
...anybody else experience this problem ?
Not since I switched to Linux.
How are you making out? I must disable hibernation to get mine to sleep.
Command prompt (admin)
powercfg -h off
Note that you can make your own shutdown script. Go to https://docs.microsoft.com/en-us/sysinternals/downloads/psshutdown and download and install PsTools . Then right click on the Desktop and chose New > shortcut, and paste C:\Windows\System32\psshutdown.exe -d -t 0 (that is a letter, not a zero) in the Location field. Then create shortcut keys on your keyboard (hold down the keys like Alt and X).
It’s usually a device waking up the machine.
Click Start > Run > type ‘cmd’ (no quotes)
In the command window, type:
powercfg /devicequery wake_armed
That will show you a list of devices that can wake your machine. Now click Start > Run > type devmgmt.msc
This will bring up Device Manager with all of the devices attached to your machine. This part might be a bit tricky, but you have to find the devices that correlate to the list from the power config output.
For instance, if you see something like “Intel Ethernet Connection,” this is likely under the “Network Adapters” heading in the Device Manager. Double-click that entry, and you should see a tab in the window that says “Power Management.” Remove the check mark from the box that says “Allow this device to wake the computer.”
