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).
