Battery Status & Fn shortcuts issue after waking from sleep #1

Open SukkaW opened 4 years ago

SukkaW commented 4 years ago

I am using ThinkPad E480 with my own EFI. I have noticed that the battery stat won't update after waking from sleep:

It seems that those two problem are connected: either Fn & Battery status work at the same time, or the two neither work at the same time.

I am wondering if you have the same issue (since you already said Lid close not working after sleep).

@SukkaW Yup, I'm also experiencing the battery status mismatch after sleep, and the Fn keys not working properly with FnLock on. From all DSDT debugging I did, I suspect at least a couple of these are related to each other / have the same cause... I always looked at the battery status mismatch separately from the FnLock issue, because IIRC the FnLock issue was consistent with every sleep, but the battery issue seemed to only occur if I changed charging states (e.g. charging -> unplugged) during sleep.

The issue over at the E580 repo has some interesting info. I haven't looked at the WAK methods in almost a year, but would be interested in revisiting it. My machine is still running Mojave so there is merit to it as well 😄.

Battery status & Fn Function are both related with EC (More specifically, EC event become untriggerable after S3 sleep).

Currently I am using https://github.com/zhen-zen/YogaSMC to read some EC value, to see if it changes after wake.

There is same linux problem with E14,, https://github.com/masksshow/Thinkpad-E14-15-AMD-Gen-2-FIX

I have check the script but it only change H8DR from 0x00 to One.

I have tried it in Lenovo E14 but problem is still there
