Hi everyone,
When I bought my laptop 3 years ago I had no trouble at all to use XTU or TS to undervolt the laptop. Fast forward, recently I noticed that XTU has greyed out the core button and using TS has no effect or whatsoever on my machine. Is it true that I cannot longer undervolt my machine?

BIOS is v1.26
Win 10 2009 (10.0.19042)

    Its the 8750h right? I know that its been disabled on the 8th after June 2019ish and 9th/10th gens, but i think you laptop was before that 🤔 Whats the XTU / XTU driver version?

    actually it's been awhile I haven't used XTU and it was version 6 something. I usually used XTU to play demanding games to cool down the temp. I had no such prob using XTU since 2019.So when I tried to undervolt my laptop, nothing happened. So I tried to download the latest XTU which is version 7.3 from intel website and now, the core option is greyed out. does this happen due to win10/bios upgrade?
