BIOS Downgrade Lenovo Ideapad 530S-14ARR

Hello! 

I am having issues with my laptop throttling extremely much and not booting if turned off under 21%. I'm currently running 8PCN55WW (bios version) and have heard that downgrading to 8PCN50WW fixes these problems. 

What's an easy way to downgrade BIOS to that version? I've found it available for download on a website. 

Help would be much appreciated. Thank you!

Hi,

 

I don't recommend downloading or installing stuff from "a website".  You can get the version you're looking for by using the SUPPORT link above, copying the 55WW BIOS exe link and modifying it to get to the 50 version.

 

I don't usually recommend that either but at least it comes from a known source.

 

good luck,

Z.

Hi, I can't find the BIOS version anywhere in the support section.
