Hello Thomas, here`s how I did it, step by step.
1) install acpica-tools apt-get install acpica-tools 2) Grab the DSDT of your device cat /sys/firmware/acpi/tables/DSDT > dsdt.dat 3) Decompile the dsdt.dat iasl -d dsdt.dsl 4) Open the dsdt.dsl with whatever editor tickles your fancy e.g. xed dsdt.dsl 5) Delete everything with a * in front, first line should be "DefinitionBlock" 6) Raise the last number in Definition Block by one e.g.: DefinitionBlock ("", "DSDT", 2, "FUJ ", "FJNBB6D ", 0x010C0000) ↓ DefinitionBlock ("", "DSDT", 2, "FUJ ", "FJNBB6D ", 0x010C0001) 7) Search for the string "OperationRegion (ERAM" for me it was at line 18751; your mileage may vary 8) Replace the entire line with this one: perationRegion (ERAM, EmbeddedControl, Zero, 0x0100) 9) Save and Exit 10) Recompile the dsdt.dsl (Note: This WILL show loads of errors and optimizations, I didn get to read into those yet) This will give you a dsdt.aml that should work. 11) Proceed as above Hope this one will work, have a good one :) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1956177 Title: battery not detected by ACPI Status in linux package in Ubuntu: Confirmed Bug description: On my freshly installed Fujitsu Lifebook A3510 now running kubuntu 21.10 with kernel 5.13.0-22-generic, there is an issue with the internal battery.
