Hey, @Hyper, could you share your temps? In idle and load, and CPU wattage (if you use ThottleStop). I'm currently also using TPFanCtrl2 by FanDjango to keep it a bit quieter. Also would be interested if someone made undervolting possible. I'm also using it with DGPU to display, because when on IGPU and idle, the NVIDIA stays in P0 Powerstate and draws 20W. I used PTM 7950 on it and still gets pretty warm even on idle when staying on te ground (60-70 degrees on idle - but drawing around 20W - limited to 24 in ThottleStop). The moment I lift it up a bit, temps go really down, like 50s. I changed the PTM twice and pressed the heatsink on it, also tightening the screws to make sure it has good contact. I added a Samsung 990 Pro and a Crucial P310 drives, and they sit at aroung 63 and 59+ temps. I think there is something wrong or early stage with their power drivers, as I applied the same PTM on my G3 Zbook and in about 2 months I saw big results, like it sits in 39 degrees in full summer on idle (but with 6-7W CPU power and 140mV undervolt). I stay up to date with BIOS and drivers via Lenovo Vantage and Windows updates (althogh it's 23H2, because 25H1 seemed very buggy)

Can anyone share a previous to 1.30 BIOS version, as this one keeps my DGPU always active and on 20W P0 on idle?

Has anyone noticed that lately the DGPU does not turn off and does not enter idle anymore when not used?

Do you know anything about Lenovo ditching Microsoft in favor of Linux (Ubuntu)? I looked on support.lenovo but could not find linux drivers for it.

There's a new Firmware 1.28, now. Maybe you should try it.

Yeah, at the boot it goes full brightness, but in the OS it can be adjusted. I've noticed, too, that Inthel Graphics is still present.

Here's another review

I tried it and it works just fine, with the battery draining faster, as expected. Maybe it's the BIOS? I'm on 1.11

No way! What you want is no PWM and no dithering algorithms! So a true 8 bit panel PWM free is a first step; next would be no software/firmware dithering, which can be quite a hassle. So, for starters, no OLED, 30bit Dreamcolor, AdobeRGB stuff!

@Ronny I would higly recommend you to join the forum at ledstrain.org; lots of controversials infos there, due to the nature of each individual affection, but, with pacience, you might find something usefull. To give you a bait: it's not just the screen that is to blame for the jittering!

@muede in real life, without the use of the dGPU, keyboard light off and monitor brightness to about 10%, around 7 hours. If you're not in a hurry, I've heard that Panther Lake is way more economic

Also a Zbook 15 G3 upgraded from M2000M to M2200, works just fine. Kept the original cooling, replaced the TIM with PTM7950. Wonder how far it can be stretched to...😂

A quick preview to it. Seems like the vapor chamber is really that thin

EDIT: I was wrong about that, as the (big) board on top is actually the GPU; so, yeah, don't charge it in bed or on the couch! EDIT 2: be very careful where you buy the PTM7950 from, as there are a lot of fakes!
