I installed a windows 10 desktop recently which goes to sleep after a while if not used. The user reported that he left the computer there for a while and when he got back, simply pressing a key on the USB keyboard did not wake the computer up. He needed to press the power button.
I tested sleep when I was there it worked properly, I was able to wake the computer by pressing any key on the keyboard. ((I made it to sleep and woke it up right after that.)
Why is it that after a longer sleep the user could only wake the computer up with the power button, instead pressing a key on the keyboard?
There were no power cuts. Would hibernation prevent waking up from usb keyboard? Isn't there be a hardware wake up event for USB? – Tom – 2019-07-21T07:46:48.500
yes hibernation would prevent waking up from usb keyboard...i just tried it on my desktop. I dont think so that there is any wake up event for USB from hibernation because the whole point of sleep vs hibernation is to turn off the computer entirely while it is in hibernation ...instead of RAM the contents are saved on the secondary storage devices such as HDD of the PC. So you could unplug your hibernated PC and still lose no data. – Elmo – 2019-07-21T08:00:47.827
Apparently there is an option to wake from hibernate too with mouse/keyboard, so it is supported: https://www.tenforums.com/general-support/102807-how-wake-hibernation-only-through-power-button.html

OK, I haven't tried it, just googled it and linked to the discussion I found. There are others too: https://www.tenforums.com/performance-maintenance/33596-pc-wakes-hibernation-mouse-keyboard.html
