Hello. I have tried to follow above instructions carefully, recompiling my own file. However for me its not working, unfortunately battery is still not recognized.
I followed these steps: 1) install acpica-tools sudo apt-get install acpica-tools 2) Grab the DSDT of your device sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.dat 3) Decompile the dsdt.dat sudo iasl -d dsdt.dat 4) Open the dsdt.dsl with whatever editor tickles your fancy sudo xed dsdt.dsl 5) Delete everything with a * in front, first line should be "DefinitionBlock" (For me that include Firmware Error (ACPI) in line 1 and 2 - if that could matter: Could not resolve [^GFX0.CLID], AE_NOT_FOUND (20190509/dswload-388) Could not resolve [^GFX0.CLID], AE_NOT_FOUND (20190509/dswload2-369) 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: OperationRegion (ERAM, EmbeddedControl, Zero, 0x0100) (I had OperationRegion (ERAM, SystemMemory, 0xFE508300, 0x0100) to begin with) 9) Save and Exit 10) Recompile the dsdt.dsl (Note: This WILL show loads of warnings and optimizations This will give you a dsdt.aml that should work. I did that with: sudo iasl -ta dsdt.dsl and got the aml file just with warnings. 11) Proceed as above sudo cp dsdt.aml /boot/ sudo cp 01_acpi /etc/grub.d/ chmod 755 01_acpi sudo update-grub reboot Still just the same :/ Can anyone point me in the right direction? PS. BIOS v. 1.12 (freshly update through Windows, Fujitsu DeskUpdate). Br.
