Windows 10: Unclean shutdowns & reboots from sleep. Syncing or power supply error?

My computer keeps shutting down from sleep mode without shutting down. It's connected to a UPS so it's not an outage. It could be the power supply unit (I bought a cheap one after the last one gave out, just to see if the motherboard was wrecked.) I noticed that the shutdown last night was at the same time my phone synced with the computer. I don't know how that would happen. I also have a lot of critical events over some zune app. I'll see if I can post something here if I remember how.Any way to test if it's a power supply problem without ripping out the thing?

missing sleep menu in power

Hi,

Missing Sleep option in Power menu is usually caused by outdated or corrupted device drivers. For us to better assist you, we would like to ask the following:

• Have you made any recent changes on your computer prior to the issue?
• When you check the Power options in Control Panel, did you mean that the Sleep option is not displaying in the Shutdown settings?

If you haven't check the Shutdown settings in Control Panel, we suggest to do so and make sure that the Sleep option is enabled. To check the Shutdown settings, follow these steps:

• In Cortana search, type control panel.
• Choose Control Panel from the list.
• Click System and Security and select Power Options.
• Click Choose what the power buttons do in the left pane of the window.
• Under Shutdown settings, put a tick in the Sleep
  box and click Save changes.

If the Sleep option is already enabled and it still doesn't appear in the Power menu, we recommend that you keep the device drivers up-to-date. For your reference, check this article on how to
update drivers in Windows 10.

Update us with the outcome so we can provide further assistance.

 

Power supply getting OFF while putting the PC on Sleep mode.

Hi...Have you tried my suggestion?...I have had issues with 'Sleep' mode and it was always due to 'Video Adapter'.

The Power Supply can be controlled by the way you have your settings configured.

It can be a simple setting but not the 'Power Supply' as you have noted.

What Video card or system are you using {on board or added and installed}?
