Keyboard not working after sleep
My keyboard does not work after my Dell XPS 15 9550 wakes up from sleep. I have to swipe up on the screen in order to type in my password to log in. Then the keyboard works fine.
I don't know if this is a hardware issue or a Windows issue.

I already have the latest drivers for both my keyboard and mouse. For method 2, I could not find the power management tab in the device manager for the devices. Is there another way to get to the power management for the devices?

Hi,
Thank you for your reply.
Kindly login to the system as admin.If you are using windows 8 or above you can search for " power management" directly.
Thanks

I still can't find any power management anywhere. Not even when searching directly in Windows.
This is the window I get on my mouses and keyboards via device manager. I am logged in as an administrator on my computer.

Hello,
I have the same problem and the tab "Power management" is missing (in Administrator also).
Any solutions?
Thanks a lot!
