Windows 10: Why does my PC hang during connected standby?

Hi all,


I have a Dell XPS 9310 which I bought in Jan 2021 and is running Windows 10.0.19042 Build 19042.


For around 6 weeks now, whenever the PC goes to sleep connected standby, after a few minutes of sleep, it becomes unwakeable: high fan speed, black screen, unresponsive. Plugged in, it will stay like this permanently. Or if on battery, it will just run the battery down until it dies. I have to hold the power button down to shut it down and reboot - and it then works fine until the next sleep.


Event Viewer says it's entering Connected Standby. There are a few info/warning events after that point but nothing stands out.


Dell Support has had me run Power Troubleshooter, try to disable connected standby you can't in the latest Windows 10 build, do a clean boot via msconfig, create a fresh user profile, run SFC scan, DISM /Online /Cleanup-Image /RestoreHealth - but nothing works.


Before they make me do a clean installation, does anyone have any ideas for how to find out what is happening to hang the system whilst in connected standby?


Thanks,

Martin

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

pc hangs

I once had an old DVD drive which caused boot problems - I had to remove the DVD.
Other ideas:

1. Check / replace the BIOS battery - my desktop PC fails to boot if this is below 2.9V. A new battery should be 3.2V.
2. Corrupted BIOS - reflash the BIOS with the latest version, set BIOS defaults, reboot then set your preferences
3. PSU problems. The is a sequence of signals between the PSU and motherboard which must work for the PC to boot. I once had a PC which failed to boot since the PSU was not outputting the 5V standby line. Check by replacing the PSU or the "paper clip test" Is my power supply dead?: The Paperclip Test :
4. Check you only have only one drive connected having an active partition since multiple active partitions can confuse the boot process. I use MiniTool Partition Wizard the check for active partitions and reset to inactive those other than the boot partition on the system drive.

 

PC Fails to Standby

I've come across this issue in recent weeks...of course I've been super busy so I would've posted sooner but I'm looking for some suggestions.

I usually just put my PC in Standby mode, have for a looooong time now. And about a month ago or so, I noticed that my PC was shutting down instead of going into standby mode, with that coming up with the Windows Shut Down Improperly do you want to start in Safe Mode prompt every startup after I attempt standby mode.

Weird thing is, my Mouse and KB light up when I try to wake up my PC. So I'm not sure if this is an HW or SW issue. I've tried a few tricks, cleared bios, ran stock, oc'd, tried different mouse and kb, tried windows patches, removed programs, cleaned vid drivers, etc. Not sure what the hell is up...and I'm about ready to format and reinstall windows 7...I've never come across this issue before, and it seems there's a million answers from years ago, not as much recently, and nothing has done anything to resolve my issue. I guess if you guys have some suggestions let me know...I plan on smoking through a reinstall this weekend if I can't get it sorted....pain in the ass because this install isn't but several months old as-is and there is NOTHING else wrong with my PC.
