Nekem is ez kellett T60-hoz, 65W-os táppal, akksi nélkül :
Is the ThinkPad running on a 65W power adapter?
Either replace the 65W AC adapter with a 90W AC adapter, or
Install a battery
Nothing else works and you know what you are doing?
Add "processor.ignore_ppc=1" to kernel boot command line.
This allows to disable BIOS frequency limit, but can be cause the
computer to malfunction if its power consumption is higher than
65W and you are running off a 65W AC power adapter with no battery
installed.
