Hello Dear Fellow Precision users!

So I've been facing this issue for quite some time now (about 7-8 months), but it only occurs randomly and every now-and-then (about once a month or two). So it is nothing that bothered me enough to take action.

Until now - it occurred two times in the past two days.

Unit: Precision M5550, UHD Touch, i7-10850H, 64GB, T2000, W10Pro

Long story short: Imagine working smoothly, going on about with your day, and then - POOF - laptop suddenly goes dark and starts the shutdown procedure, as in normal hibernating.

Looking at the event log:

Trigger: event 524, critical battery trigger

Effect: Event 42, entering sleep mode, reason: battery

And then laptops shuts down (hibernating). Without any other issues I can turn it back on and continue working. Battery remains at normal capacity during the event.

Battery status via Power Manager:

Battery is working perfectly (up to 10h when in power-saver on battery only). So I don't suspect any issues there (checked with external software as well, returns good parameters).

I suspect drivers - the question is which. Has any one had any experience with the described issue and found any solution? Could it be the improved Optimizer (with Power Manager capabilities)?

Looking forward for any insights!

Regards!
