Laptop's keyboard lacks "Power Management" tab in device manager

mibaup · 02 Dec 2020

My laptop's keyboard isn't waking up the laptop from sleep.
I went to device manager and right-clicked the laptop's keyboard which is marked as "Standard PS/2 Keyboard" (And not HID Keyboard Device - like my wireless USB keyboard), then Properties, but it doesn't have the Power Management tab like the wireless keyboard. So I can't tick the "Allow this device to wake up the computer".

Is there a way to fix that?

thanks

See here: Allow or Prevent Devices to Wake Computer in Windows 10

Try Command Prompt method.

Has your laptop keyboard ever had a Power Managment tab?

Some devices simply do not provide this feature. I miss it on this Thinkpad t440s.

Ok so I guess it's not about it because I just checked, there are 2 scenarios:

1) I put the laptop to sleep clicking the power button - then the keyboard DOES wake up the laptop from sleep

2) The laptop goes to sleep on its own after a while - then the keyboard DOES NOT wake up the laptop from sleep - only the power button. In this case, I also see the Windows 10 loading screen for a second, but it wasn't off because I did not see the BIOS screen. So it's like a deep sleep mode - is there such a thing in Windows 10?

There are different sleep states- and also possibly modern standby:

The powercfg command has many relevant options and you might find one that helps.
Try powercfg /? at a command prompt and proceed from there.

This article has a table with a few of the options for that command- there are many.

Hello @mibaup,

As mentioned above by @dalchina, PowerCFG can be very useful in situations like this.

This will give you a lot of Power Configuration / Management Information that might prove useful, just download and run this Batch script [ written by me ] . . .

> Attachment 309191.

It will create a PowerCFG_Detailed_Analysis.txt file on the Desktop.

It will also create the following files on the Desktop . . .

Battery-Report.html
Energy-Report.html
System-Power-Report.html
System-Sleep-Diagnostics.html

I hope this hleps.
