I was also able to reproduce this issue with a brand new, never-used, Beelink SEi i7-12650H mini-PC. I unboxed the mini-PC, powered it on, went through initial setup, then allowed Windows to update, as well as running the Intel Driver Assistant to update the drivers on the system. Sure enough, Intel ARC 3.0.101.5382 drivers installed. Upon the display going to sleep on its own after 25 minutes, the system became unresponsive, requiring a hard power cycle to return to running status. Same exact problem the Beelink i5-1235U mini-PC is having.
The new i7-12650H mini-PC was connected to the same monitor, etc. as the i5-1235U Beelink mini-PC. So I now suspect there's a couple of issues going on...
Either the new Intel ARC drivers do not like the 74.97Hz refresh rate of the monitor (so I have set to 60Hz to test), OR there's a firmware issue that spans multiple Beelink mini-PC systems using similar architectures. The GPU inside the i7-12650H is a 12th gen Intel UHD GPU, while the i5-1235U uses Intel Iris Xe graphics. I bolded the refresh rate of the monitor I'm using because it's not a common refresh rate. Both systems are running fully updated versions of Windows 11 Pro, 23H2.
I will report back once this system has run for awhile at 60Hz refresh rate. |
