Has anyone noticed that computer will not sleep since installation of .662?

I just updated to .662 last night and my PC slept as usual without issue.

That said, have you checked for any new drivers - particularly GPU or soundcard drivers? Most of the time it's drivers that prevent a PC from sleeping.

Check to see if any of your devices got changed to allow to wake up the computer, under the properties Power Management tab.

What "devices" should the OP be looking for? And where?

Anyway, that shouldn't need to be done and I've never had it happen to me in any builds I've done. In fact, I don't even mess with the power management settings for any of my devices.

It's happened to me several times after an update. In the Device Manager check Human Interface, Keyboards, Mice and Network Adapters. Doesn't hurt to look, and could solve the problem.

Happened to me only once. It was network adapter. but it was like a year ago, when MS messed with local networking things.. Had to disable " allow this device to wake computer"

I stand by my statement, but you are correct... it doesn't hurt to check.

And if you're going to tell someone to check something it helps to tell them where to look. Thanks for confirming.

Peace

Device manager / Network adapter /double click / Power management tab

In my case of trouble, "Allow only magic packet..." was unchecked" - a lot of computer wakening...
