Recently I have started to experience intermittent abrupt loss of power on my once stable system. In the last fortnight it has occurred 4 times, so I can imagine it's going to be a problem to identify!
After the second occurrence I turned of Anti-surge detection in the BIOS because following each sudden power loss I was presented with a warning that the motherboard had detected an unstable supply and shutdown to prevent damage. However this had no effect because a while after it happened again. Having checked Windows Event Viewer I found an entry suggesting that the BIOS was attempting to do something that Windows did not like and so it had been ignored but flagged as a warning. The associated help suggested checking for and updating the BIOS. I was on version 1402 but have now updated to 1601.
Again tonight the problem has re-occurred and having checked the Event Logs I can again see the same warning...
": The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS."
But now my system is using the latest BIOS, and I manually cleared the logs after updating to be sure that any new warnings were related to the new BIOS. Tonight the system had been running for approx 4 hours and at the time of shutdown (power drop) it was idling doing nothing with the CPU temp sat around 30 degrees. The PSU is the obvious culprit and I will test further, but in the meantime I'm interested to know more about this particular warning message.
This may have nothing to do with my actual fault and I've plenty more problem solving to perform to try and identify the actual cause. But is anyone else experiencing the ACPI warnings in the event viewer? Should I be concerned by these? I realise that warnings and even errors are common place in the Event Logs but I'm concerned that this particular warning is suggesting that I check with the manufacturer for an updated BIOS!

Hi Code_Frenzy
As you say it sounds like your psu is on the brink, I don't have any ACPI errors but I do have a ton of events and my pc shows no signs of any problems.
Hmmm this is the first time I've looked at this 21,498 events? Seems like a lot compared to yours.
I wonder why it would put a whole slew of these for the same date and time? I know this is due to a driver crash from overclocking my gpu. I don't mean to get off track but I haven't seen any ACPI errors in my event log.
Are you using ai suite? I'm not using ai suite.

I will post this to clear your event logs that Arne sent me, I feel like me pc just got a bath or something. 😄
There are 4 methods I used the .bat file method, scroll to the top.
Thank you Arne !
