Disabling CPU throttling on Lenovo 720

2018-01-14, 16:11 PM

So I recently purchased a YOGA 72015IKB, and noticed that whenever it runs on battery, the CPU never exceeds 800MHz! My first reflex was to disable CPU throttling in Windows, but no dice, still stuck at 800MHz.

 

I did a little digging and found out that for some reason the BD PROCHOT flag was always set when on battery power, forcing the CPU to throttle down the clock when on battery. Using ThrottleStop I was able to disable this flag and everything went back to normal, but I feel it's a bit silly that I have to use a 3rd party app in order to unlock the full performance of my laptop.

 

I read that you can disable this in the BIOS, but these consumer-level laptops have limited BIOS configuration options, and I cannot find anything related to throttling. I updated the BIOS to the latest version v2.00, still nothing. Anyone else encounter this?

Same, although I'm being throttled to 1600Mhz, nearly half of what it should be reaching.

Yes, same problem for me on the yoga book 920, very close to selling it because of this and moving back to Macbook like I should have in the first place.

Same, I use throttle stop, but even then the max I have seen the cpu get is to 3.4ghz, not 3.8 like it claims to be able to.

FYI guys I fixed this problem by sending it back to Lenovo, the system board was defective!
