echo '\_SB_.PC00.LPCB.EC0_.SPMO' > /proc/acpi/call; tr -d '\0' < /proc/acpi/call

@dmitriysafronov, thanks for sharing. Almost works for my Lenovo Legion 5, ie

echo '\_SB_.PC00.LPCB.EC0_.SPMO' > /proc/acpi/call; tr -d '\0' < /proc/acpi/call

returns:

• 0x0 - for balanced
• 0x1 - for turbo
• 0x2 - for quite

But unfortunately none of balances work, since:

sudo sh -c "echo '\_SB_.PC00.LPCB.EC0_.VPC0.DYTC 0x000FB001'> /proc/acpi/call; cat /proc/acpi/call; printf '\n'"

returns

Error: AE_NOT_FOUND

Where did you find documentation, or maybe you have any ideas how it could be fixed for Lenovo Legion 5?

Thanks anyways for the fix

@logical-and you can find your variant in dmesg with grep like I did. Take _SB_.PC00.LPCB.EC0_ as a word and remove symbols on the right side part by part if grep results are empty.

@logical-and example:

This is nice, thank you!
