Thinkpad S440 doesn't wake up from sleep when closing and opening the lid

As the title says.

 

Last weekend, I completely reset my computer to factory settings and updated every driver possible. Went through all the power settings that I know of, but nothing works. The laptop is set to sleep when closing the lid.

Opening it up again, the screen stays black. The green button for the Fn key stays lit and the red light pulsates. I can't wake it up and I have to shut it down by holding down the power button.

 

Any solutions?

Hi @Gebruiker1926!

 

Welcome to Lenovo Community Forums.

 

Kindly update the BIOS version of the machine and download it from our support website.

 

If still the same, try the steps below and observe if you'll see any changes.

 

  • Right-click on the Start Button to open the Power User menu. Select Device Manager.
  • You’ll see a list of categories for the devices connected to your PC. First, click the arrow next to Keyboards.
  • You’ll see one or more entries for your PC keyboard here. Double-click each one of them in turn, and select the Power Management tab. (If you don’t see this tab for a particular entry, move onto the next one.)
  • On each entry’s tab, make sure that Allow this device to wake the computer is checked.
  • Click OK, and your keyboard should now wake your PC from sleep.
  • Repeat these steps for the Mice and other pointing devices category if you’d like your mouse to wake your computer as well.

 

Regards,

Thank you for your reply.

 

I've checked the software page, but there's no update for the BIOS:

https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-s-series-laptops/thinkpad-...

 

Furthermore, when I go into the Device Manager, the keyboard properties does not show a tab with "Power Management". The mice does, and that box is checked. So, I tried to enable waking up by keyboard through the command prompt as admin and entered the following: powercfg -deviceenablewake "Standard PS/2 Keyboard". However, this returned "You do not have permission to enable or disable device wake.". Which is strange, considering it's my personal computer and I am an admin.

The problem still persists. I still have no fix.

Maybe you can used the Windows Media Creation Tool to get a fresh ISO of the current Windows build and performed an update installation with keeping your apps and data or try to update the graphics driver.
