HP OmniBook 7 Laptop 17-dc0xxx Board: HP 8D9C, version 45.36 BIOS: F.10 Symptom: hp-wmi fan1_input and fan2_input always return 0 RPM while the fans are spinning. acpi_fan (PNP0C0B:00) reports the real speed. I tested the GM fan queries in a small module. 0x11 (fan speed), 0x10 (fan count) and 0x26 (max) return PASS with a zero payload. 0x4c still returns data. Attached: full acpidump. I will attach the EC dump (ec_sys, ec0/io) as a se= cond attachment. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
