X40 rtx4090 - white screen crashes.

Hi,

Having issues with white screen crashes during gaming. updated the BIOS to the latest version on the website to 1.23. How do i update the EC? 

I'm not sure if the crashes are CPU related, when i monitor i am at 30%load during gaming and it runs at 91c. Anyone experienced this?

If it is the Intel CPU issue then I'd recommend putting the laptop in office or quiet mode, keep pushing the button next to the power one. 

Then hope that the CPU hasn't been cooked by too much wattage. 

Open up the command center app, I think power. Performance tab, create a new power profile.

There is a CPU temperature slider, I think mine was set at 95°c put it down, 75 was the lowest for me, the 4090 don't run as hot a the CPU. I scrolled down and clicked turbo fan which put them at 100%. While playing cyberpunk maxed out it was a much better experience. 

Do that, play some more of what ever your doing keeping an eye out for white screen crashes, hope they've stopped & permanent damage hasn't set in. 

I'm investigating the pl1 pl2 & pl4 power settings, the command center app doesn't seem to be documented so I'm trial & erroring it. 

I'm pre the Intel CPU issues & trying to keep it that way.  Don't let the CPU tun hot.

Hi Thomas,

I've done what you recommended. Hopefully that's worked around the issue! I tried to manage the cpu power but in Windows initially but it had not worked. 

Many thanks.
