Once the P73 one appears, definitely post on here if you are able to successfully upgrade your P53 with the 90w bios with no issues.

Im not too sure if I have the gut to be the first one to try it on P53. Do you know whether the vbios can be re-flashed to the original backup one if the first flash fails and bricks it?

Did you ever find a solution? I have been trying to fix this since I received my machine to no avail. Lenovo wants me to send it to Depot however I'm not looking to lose my machine for a month...

How do I update the vbios for the RTX5000? I know how to do a regular BIOS update however not vBIOS

I have tried disabling all Lenovo thermal services however that does nothing... The machine operates as it is supposed to for about 2 minutes then enters limp mode with the RTX5000...

Flashing(with nvflash) the vbios could brick the gpu, even though I had seen a video teaching how to unbrick it on youtube. the vbios in P73 has a 90w limit, you can flash it with a vbios with same device ID and rev., but dont go too high, because the circuit is not design for that. the next up above 90w is 110w.

my P53 does not have the issue you said, but just annoying to see that it gets Power limit at 80w while the gpu temp is only 65c-70c.

This appears to be a common issue with P73/53;

There is another concurrent thread going on with P53 and identical symptoms; Personally now three other guys with same issue;

 

Another gentlemen suggest full reinstall; Did work for him; And afaik id did work for three other guys too

 

As far as driver uninstall, I removed handfull thereof, six or so, anything related to power management, thermals e.t.c.

Make sure nothing installs them back if you go that route;

 

But, maybe, do clean install first (manually pull latest versions of whatever, don't rely on advantage thing, it isn't reliable)

 

It is pity there is no official advisory from Lenovo on this one

Im going to try the fresh install as I cant keep the thermal drivers from reinstalling... how do I go about keeping the lenovo drivers from installing with a fresh copy of windows?

You may not need too/// 

 

Some sources say that you can install everything listed on a web site post clean windows install

It seems to work alright for them so long original windows build is wiped

 

You'll have to try and let us know :-]
