Hi RehabMan.
After getting a clean dump and patched the DSDT with "[bat] Lenovo X230i", battery status is working fine on my ThinkPad P51. Thanks for your help!
Maybe you can add a comment in the patch to tell others the patch can also work on Lenovo ThinkPad P51.

hi ,can you share your dsdt? I can't deal with the batter of my p51

shouldn't share DSDT, as you can cause more harm than good, ie, different BIOS versions, different BIOS options etc.

you should patch your own DSDT

i disassembled your files and saw an error, i commented out lines 153 and 155, resulting no errors

i haven't done any patches, that can be your job

Hello @RehabMan,

thank you for your great guide and sharing all this knowledge

Please find attached:

• Hardware information about my notebook (Tuxedo Infinitybook 13v2 [a Clevo rebrand])
• The battery DSDT patch I created using your guide
• My native acpi files

Battery status is showing and changes normally. Still I created the patch today and did not have much time to observe it.

EDIT: Sorry, there is one issue: The status lags behind and is not updated for some periods of time (see screenshot added to attachment).

Best regards,
Fox
