x220 - Enable Instant resume not possible?

[ziggie216]

Already updated the power manager to the latest power manager and i'm unable to keep the InstantResume enable. I check the box, click on OK, and when going back to the "Close the lid" window, I see that InstantResume has been disabled again. Running default settings for PowerManger, I have not changed anything.

hey ziggie216,

could you try updating the bios and chipset of your X220 and try the Instant Resume again ?

x201i 3626NP4, same problem

I tried different versions of power manager.

earlier it's work, but now...

windows 7 64bit

power manager 3.61

Any resolution on this ?  

My "enable instant resume" checkbox  is also always disabled (and CANNOT BE CHECKED) even though I have always installed the latest updates.

From what I remember testing the Instant Resume is pretty useless, basically your laptop doesnt go to sleep at all, just keeps on running with the lid closed, so when you open it, duh, it's instantly on.

i found solution!

in your thinkpad you must install ThinkVantage Active Protection System, make sure that chekbox(tab Configuration) Enable Active Protection  System is ON. after check Event for Lid Closed: Sleep or Hibernation, and you can use Enable InstantResume.

uhhhhhh....

I have the same problem. i can select it, but when i reopen power manager, InstantResume is unselected again.

I have a T420s with power manager v6.30. I have a SSD, so i don't have the acitve protection system software installed.

Is that the reason why it doesn't work?
