Administrators Hervé Posted April 11, 2023 Administrators Share Posted April 11, 2023 Check your BIOS logs. Any ASF2 related entries? Link to comment Share on other sites More sharing options...

Administrators Hervé Posted April 11, 2023 Administrators Share Posted April 11, 2023 No ASF2-ralted power off then, which is re-assuring because these are a nightmare when it comes to root cause. So, other than the ACPI-related cause, nothing other than your own manual forced shutdown, at least for today. Regarding ACPI Power Management shutdown, my guess would be that it's due to excessive heat causing CPU to go into protection mode. Do you have any CPU T° monitoring in place at all like with HWMonitor app? You'll have to post a zipped copy of your OC EFI folder or, at least of that SSDT-5470 patched table of yours, for us to provide further assessment. Using these single SSDTs really is best avoided as, once again, likely to be proven more problematic than beneficial... Do you experience the same behaviour if you disable your (DW1820A) Wifi card in BIOS or physically remove it? I know you apply the required ASPM patch but...

OmarMohamed6528 Posted October 17, 2023 Share Posted October 17, 2023 Hey, I have the exact same problem, and I was wondering if you happened to find a fix for it? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 18, 2023 Administrators Share Posted October 18, 2023 Sometimes, you also have to re-calibrate the battery: go to BIOS settings, let it fully charge, then let it completely discharge until laptop turns off. You may find you need to repeat this a couple of times. Recently had to do it on my E7270 as it would power off unexpectedly when battery still showed 40% to 50% charge. 'been running Ok after battery re-calibration. Link to comment Share on other sites More sharing options...
