Re:Fix for Lenovo's laptop-cooking BIOS update

As inconvenient as it may be, it seems like Windows 10 requires a full re-install not an update if you wish to switch BIOS modes as mentioned by a previous poster.

Re:Fix for Lenovo's laptop-cooking BIOS update

That's an interesting observation!

 

Why that? My machine has integrated Intel graphics chip (UHD 620). And the Intel driver update utility would notify something like:

"Your laptop uses a graphics driver individually engineered by your laptop manufacturer. Intel cannot update your graphics driver - using a generic Intel driver can cause problems. Please contact Lenovo for any graphics driver support"

 

:o

 

 

Intel driver assistant would not report anything like that for all the other Intel hardware that sits on my board (e.g. CPU, Wifi, Bluetooth, Ethernet GbE, Realtek Audio,... )

The interesting test would be now:

boot to safe mode - remove the graphics driver - and see if the freezes still occur using a basic, generic driver (safe mode).

Why? I changed S0 to S3 without reinstallation Windows 10 (20H2) without any issues.

Quote from Microsoft: "Switching between S3 and Modern Standby cannot be done by changing a setting in the BIOS. Switching the power model is not supported in Windows without a complete OS re-install."

 

In other words, you're on your own.

What @bananaman said.  You're on your own. I've experimented with changing sleep modes w/out reinstalling Windows.  Seemed to work, but instabilities showed up over a few days.

I would not said "seemed to work" if "instabilities showed up over a few days". In my understanding this is "seemed not to work". But I don't believe that time (mentioned few days) is reason of instabilities. It either works or not right away.

I've read MS requirement to reinstall a Windows, but I really don't see any issues after switching form S0 to S3 in BIOS with my 20H2 on Carbon Gen7.

So I think MS's reinstall requirement is redundant. May be the requirement is related to old versions of Win10 but not for actual ones.

Thank's!

Same here, S0 to S3 went without a hitch, no reinstall needed.  Possibly if you've started with S3 and then later switch to S0, which is utterly different from any traditional power management scheme, you may need to do a reinstall, but going to S3 is no problem, you just flip a bit in the BIOS and you're done.
