How interesting... particularly since I'd provided you with:

in this thread. So let's look at that last uri:

Solution

Make sure no BIOS setting is limiting the CPU frequency range (like
"thermal management" = "BALANCED").

    Buy a 90W AC adapter
    Don't use the laptop without the battery pack

Other solution than using the laptop with the battery pack always
inserted is to add "processor.ignore_ppc=1" to kernel boot command line.
This allows to disable BIOS frequency limit, but can be mischievous to
the computer if it's power consumption is higher than 65W.

and it appears that it still goes back to your power..
