11th gen, Windows, can't seem to get the laptop to sleep after about 5 sleeps

I seem to be facing a bit of an odd issue with my 11th gen on Windows 10.

  1. System boots up fine. No problem here.
  2. Put system to sleep via Start → Power → Sleep. No problem here.
  3. Display powers off, power button goes into ‘breathing’ LED pattern. All good here.
  4. Wake system up by key press. System wakes up. No problem ehre.
  5. Repeat Steps 2-4 about 5 times. Mostly good…until around the 6th time or so…and the system would no longer go into sleep…or takes awhile to get into sleep. Display would be off, but the Power LED stays on.

Has anyone seen this happened to them?

(BIOS 3.10, SN850, USBPD plugged in, 76% charge limit, battery level at 76%, wifi connected.)

Yeah, there’s some strange inconsistency (timeliness) between multiple sleep / wake cycles.

I noticed that when it doesn’t sleep, all I had to do was to unplug the USB-PD. This would power on the display for a few seconds, the system will THEN automatically attempt to get into sleep…takes about 10 seconds…but it will eventually sleep.

It looks like the USB-PD is inconsistently preventing the laptop from entering sleep at times…and other times, it would succeed even when plugged in.

This ‘unplugging USB-PD’ business triggering a screen wake / power on is another ‘weirdness’. Like, I don’t expect unplugging a power source should / would trigger a screen power state change.

I’m really trying to give this unit a 2nd chance after mostly having left it on the shelf over the past year…now with expired warranty (Only had about 200 hours of power-on time). I was hoping something so fundamental would have been tested and stabilised / fixed over the course of a year. It’s not like we’re trying / expecting a paradigm shift in how a laptop should sleep / wake.
