It seems to be a general Cherry Trail problem for newer kernels.

The suggested workaround is ti set <tt>intel_idle.max_cstate=1</tt> in the kernel parameters. So far the Lapbook works without freezes since I added this to grub startup routine.

I flashed the modded bios version 1.8 from XDA forum and the TDP now is set to 7 W / 15 W exactly as I want it.
At XDA they wrote the TDP is set in the CPU configuration -> Set Configurable TDP Boot Mode to UP and guess what it does the job. When I set it to nominal as in the original bios I am back to 4.5 W.

Thanks Bonnom, unfortunatelly your guide does not really help me…
I do not want to disable the temp. sensors, but just have my CPU PL1 power limit changed from 4.5 W to 7 W automatically at every boot.

When I restart Windows HWInfo tells me the PL1 power limit is at 4.5 W. As soon as I start the Intel XTU the PL1 limit changes from 4.5 W to 7 W (I am just starting Intel XTU, not loading any profile etc.). I can even close Intel XTU and exit it, but when I restart Windows I am back to the old 4.5 W and have to manually open Intel XTU again….

Hi Bonnom,
Intel XTU works for me but somehow the system does not remember the settings after several restarts I am back to 4.5 W and 15 W.
I tried my luck then in the bios and eventually also found a setting saying 4500 mW, changes it to 10000 mW but still I get only 4.5 W in Windows.
I changed it here: “Advanced” tab -> “Platform Misc Configuration” -> “DPTF Configuration” -> “Minimum Power Limit 0”, “Minimum Power Limit 1”, “Minimum Power Limit 2”
I also enabled the P1 and P2 power level setting here: “Advanced” tab -> “CPU Configuration” -> “Platform PL1 Enable”, “Platform PL2 Enable”, and increased it to 10000 mW but still the same 4.5 W limit…..

Would be great if you can post how you did it.
