Laptop CPU clock speed stuck at 0.40ghz

Hi.

I am currently using Asus vivobook s15 and there is a weird issue with my laptop.

After 10 to 15 minutes of powering it on and doing some intensive tasks like gaming and video editing, laptop suddenly slows down and when I open Task Manager I see that the CPU clock speed is stuck at 0.4 gigahertz. I ran Intel extreme tuning utility to analyse the issue and on stress testing the CPU I found out that after 10 to 15 minutes of stress test the CPU slowed down to 0.4 gigahertz.

Everything including the BIOS is up to date.

Can anybody please help me out with the issue?

Had this problem with my Lenovo Y520, thermal paste on the CPU was dried out.  The temp sensor that XTU reads was fine, but the die has tons of sensors that it can monitor and one that is not user visible was tripping over-temp protection.

windows 10? i had this issue on my desktop rig. i fixed it after weeks of this BS. only way to fix it was to restart PC. and i know my thermal was fine and i was not bottlenecking it somehow.

i fixed this by going into Power Options > make a new power plan > click that power plan > go to advanced options once in there. and find  "Processor Power Management" and mess with the "minimum processor state" and maximum. and anyways, the "system cooling policy" switch that to active and test your cpu speeds. if it doesn't work, make it Passive. Try it.

I actually resolved this issue by downgrading my Yoga 530 14-ARR BIOS from version 8mnc52ww to 8mnc50ww.

You can try to download a previous BIOS version by going to https://download.lenovo.com/consumer/mobiles/"your bios version".exe without the quotes.

Hey! I have exactly the same issue on my Yoga 530 14-ARR.

But I don't find the old BIOS version anywhere. The link you posted is not working. Do you know where to get the old BIOS Version?
