Problem Details: A few ThinkPads fail to initialize EC register 0x2f both in the EC firmware and ACPI DSDT. If the BIOS and the ACPI DSDT also do not initialize it, then the initial status of that register does not correspond to reality. On all reported buggy machines, EC 0x2f will read 0x07 (fan level 7) upon cold b...
