Powermanagement issues
Always when my Thinkpad X13 Gen1 is unplugged, I get power management issues (I think) . The laptop then freezes and makes sometimes a tut-toot-tutely-toot sound.
I have installed CPUFriend and CPUFriendDataProvider.
I generated the CPUFriendDataProvider.kext with CPUFriendFriend and also generated and installed a ssd_data.aml and some IOPlatformPowerProfile.
Here the ssd_data.dsl:
And the IOPlatformPowerProfile:
Any what could be wrong with these?
