Won't Wake Up from Sleep ThinkCentre Edge 72

Fault has just occured.

Sleep set to 30 minutes, but computer will not wake up.

Have tried differant Power Plans but no solution.

Have run Lenovo Diagnostics but NFF.

Have run Microsoft "Troubleshoot", NFF

Think this srated after installing "Power Manager" Program, I have now uninstalled this.

can only wake computer by disconnecting from mains supply & the restarting or setting Power Plan to "Nevor Sleep"

I have the exact same problem with my IdeaCenter A730 and no one has responded to my posts. This problem seems to be common and no one has offered any assistance or feedback.

Further thoughts to help:-

This problem has been caused by Lenovo issuing a BIOS update 1.70 that causes the problem, so Lenovo should pay for your repairs even if machine is out of warranty.

Suggest get Lenovo Service center involved ASAP

Hope this helps.

Re: Won't Wake Up from Sleep ThinkCentre Edge 72

Thanks for your reply Johnoo - 

I fixed my problem yesterday after reading somewhere that it could be caused by an outdated display driver. I downloaded the intel driver utility and used it: http://www.intel.com/p/en_US/support/detect

The utility told me I was using an outdated display driver. I updated the new one, restarted my computer, and now I have no issues. My PC "wakes up" properly from sleep and when the screen goes play, it comes back on after mouse/key input.

Thanks again.

I have this same problem with my Edge 71. After updating the BIOS and checking the display drivers, it still won't wake up. Please help!

 

Thanks!
