Power Off In Sleep

[Sam.MP4]

So I usually have my sleep settings to turn screen off after 45 minutes and sleep after an hour. So I woke up and I pressed a key on my keyboard and it didn't turn on. So I pressed the power button and there it goes. So I went into event viewer to look for critical events and there were two. One from me hard rebooting it and one from i don't know. It does involve sleep so can you help me translate this because I don't really know what it means . Is it a power supply issue or just a bug with windows. This has happened before where when in sleep over night it shuts off but there is no critical event error. Is this common for windows PCs when you build your own?

I do know with some systems when it comes to sleep they don't respond to a keyboard press to wake them up. You have to hit the power button on the chassis (only applicable for some systems).

 

Did you have any applications open prior to sleep? Were they still open?

 

Also if you don't have a UPS it's entirely possible there was a power-outage overnight. Sleep (last I checked) suspends your session in RAM. If the power goes out (which I find in not rare to occur at night) it could cause the computer to just shutdown completely losing the sleep-state.

I currently do not have a UPS because I built my system recently and I am actually ordering a CyberPower UPS tomorrow. I’ll let you know if that solves it, Should I keep programs open to test what happened?

If you want to know weather or not it's actually losing sleep-state and shutting down you can leave something open, anything really, Notepad even. If it's not open the next time you find you're hitting the power button then the system did lose power while in sleep. This could be a PSU problem but depending on the reliability of your utility company a brief blip in power from the wall could cause your computer to go out.

I just tested it out waited 25 min to turn it back on and I pressed the power button and everything was still there. Is this because of the turn hard disks off after x time?

What do you mean by that about the HDD? If you put the system to sleep and it wakes up to the same state with (all) your applications open everything works fine.

 

The feature to wake the system up with a key usually is found in the BIOS/UEFI of a motherboard so you have to check your settings there for sleep-modes and how to wake your system.
