Power Mode on Windows 10 not working /max CPU frequency locked to 800Mhz

Hi,

 

PC is a Carbon X1 Type 20KG.

 

Power modes just stopped working on Windows 10, both "better battery" and "best performace" have CPU locked at 800Mhz max frequency.

 

Task manager reports 2.11Ghz.

 

After reboot sometimes it becames normal ("better battery" locked at 2.11Ghz & "best performace"@4Ghz) but after a sleep or two it gets stuck @800Mhz.

 

Any clues?

 

Thanks,

 

Luis
