[kernel-fixed-upstream]Battery not found on Clevo N350DW laptop

[Oliver]

Hello,

the laptop runs flawlessly with Windows 10 and Linux except that in Linux the battery is not found in the system. I tried launching the Kernel with all acpi_osi and acpi_os_name parameters that the DSDT presented and with acpi=force, no luck.

I patched the DSDT, it had 6 errors but 182 warnings, 250 remarks and 350 optimisations. I added under External(...) variable definitions one entry and commented out another that got me rid of the errors and I was able to compile a dsdt.aml. I duplicated the actual initrd and vmlinuz entries and cat the dsdt to the initrd. Restarted everything and it worked but no battery was found. It is completly invisible to the system.

No my expertise has reached its limits, maybe you can have a look at it.

Thank you very much, tell me what other infos you need.

Greetings,
Olli

Thank you a lot that was a good advise, with the mainline kernel 4.19-rc4 everything is working now. Even System Suspend and the backlight keys, now the laptop is just perfect.

Thank you very much ! :)
