I got several reports that compiling psmouse as module and unload it
explicitly on shutdown helps to fix things on newer HPs.

E.g. this report:
About the fan and battery issue, there are three workaround:
 - Turn off the machine and quit battery, Place the battery again.
 - Next time you turn on the machine, turn it off during post.
 - "modprobe -r psmouse" (after compiling psmouse as a module) before
shutdown the machine.
Next time you turn on the machine, battery status is working. Not sure
about the fans...
