PC won't activate out of sleep

[Craig234]

Today, twice so far, when I go to the PC after it's in sleep, it won't restart by keypresses or mouse activity like it has before. I have to powercycle. Any ideas?

More than likely, its a windows update has 'refreshed' some of your options according to its own sense of what you need to have. has done this to me personally. Your psu is an older design, group regulated (absolutely nothing wrong with it!) and those psus have a common problem with Intel C-states (the sleep modes) with any cpu Haswell or newer. The new cpus are far more economical and do not require much power in sleep modes, but the psu can't go that low, so there creates an issue. Win7 was easy to fix, but win10 has stopped much of the user control of power settings, including C-States.
So this means a trip into your Bios, what youll be looking for is a tab or page related to power settings, Some have S-1 or S-3 some have full ability to stop c-states below C-3 etc, and that's what you need, stop C-states below C-3. This still allow sleep, it just won't allow a sleep that's really deep.

Hope that helps

I have a similar situation, but with different parts. I recently bought a Seasonic G 450 PSU. WIndows 8.1 Pro 64 bit. FX 6300. Before I could wake from sleep with either the mouse or any key on the keyboard, but now I just hit the front power button and it wakes right up from sleep (not a full power cycle). I haven't fooled around in my BIOS or Windows power options since the recent install of Windows 8.1 Pro (Previously was on Windows 8 Pro 32 bit).

Yours is probably in Windows power settings, you could easily have things like 'wake on lan' 'wake on usb' etc all disabled, which can happen with some eco settings. I'd run though there and make sure your cores are unparked, power settings of 5%-100% etc. Could be in how the sleep settings are organized, with hibernation or hybrid sleep enabled etc. Won't know till you've actually peeked in the bios/power settings and adjusted the settings to your tastes.

Very interesting, thanks. I'll look at that. I'm not sure why it was working, and now is working again, on its own, and had this issue temporarily, but that's a lot of good info.
