T540p will not go to sleep when the lid is closed

I recently got a T540p and all settings in Windows 8.1 are set to "sleep" when either the power button or lid is closed. Neither of these work, the screen stays on when the lid is closed. If I let the computer idle long enough, the computer will enter sleep.

 

I've used Lenovo System Update to get the latest drivers and there is nothing outstanding.

 

Could someone please advise if there is anything else to check?

Hi Adamstirtan,

 

Welcome to Lenovo Community!

 

As per the query we understood that you are facing issue with system not going to sleep mode on your ThinkPad T500.

 

  1. Go to Control Panel\All Control Panel Items\Power Options\Choose what closing the lid dose – When close the lid – On battery sleep – Plugged in sleep.
  2. To prevent programs from waking your computer:

Open Power Options by clicking the Start button Picture of the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.

On the Select a power plan page, click Change plan settings for the plan that you want to change.

On the Change settings for the plan page, click Change advanced power settings.

On the Advanced settings tab, expand Sleep, expand Allow wake timers, choose Disable for both when your computer is running on battery and when it's plugged in, and then click OK.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Hi Hemanth,

Thanks for the quick reply. All of the settings you have pointed out were
already set as you told me. There seems to be something else preventing the
computer from entering sleep. A good indicator is that the power button on
the laptop itself does not do anything when the computer is awake. In
settings, the power button is set to put the computer to sleep just like
when the lid is closed.

Please advise further.

Re: T540p will not go to sleep when the lid is closed

look in the event viewer. There is probably a device that cannot enter sleep state. It should throw a message

Re: T540p will not go to sleep when the lid is closed

Hi Adamstirtan,

 

Please let us know the current versions of graphic driver which are installed in your system (if you are having additional graphic card then provide both).

 

Check with uninstalling the current graphic driver from the system (if you are having additional graphic card then uninstall both).

 

Hope this helps.

Re: T540p will not go to sleep when the lid is closed

Thanks everyone for helping out so far. Here are the steps I've tried with no change.

 

  1. Uninstalled Lenovo Power Management Driver > Reboot > Reinstall > Reboot. Everything is still set to sleep (power button and lid close) but neither work.
  2. Uninstalled and deleted the Intel Graphics 4600 driver > Reboot > Reinstall > Reboot. No change. Current version of that driver is 10.18.10.3958.
  3. Someone mentioned looking in the event viewer. Could you give a brief example of what specifically I should be looking for? Should pressing the power button likely generate an event?

Try running POWERCFG /REQUESTSOVERRIDE in an administrative command prompt and see if it lists anything.

Re: T540p will not go to sleep when the lid is closed

Hi Adamstirtan,

 

Run the command prompt as administrator and type ‘powercfg.exe /energy’ this will verify the error in power option, and to check the report type ‘powercfg.exe /requests’ check if any 3rd party application is giving errors.

 

Also check with disabling the Ipv6 from network option.

 

Hope this helps.
