    I've done that a dozen times with various keyboard models, always with good success. Even did it with models with kb backlight and mouse nub. It's pretty straightforward. Just remove the keyboard and completely submerge it in medium-hot water for a an hour or two. Maybe you also want to add some isopropyl alcohol after some time. Then dry it thoroughly with a towel and squish out all the excess water underneath the keys (and use centrifugal force to your advantage 🙂). Then use compressed air (like from a really strong compressor 🙂) to further blow out any remaining droplets until dry. Then put it on a towel and leave it for 24h (yes) on a radiatior to dry out completely. Should be as good as new after this. I was typing all of this on a zbook 17 g1 with a keyboard which had non-responsive keys and lagging input before this procedure.

    Yeah, basically. It refuses to boot with lid closed and being turned on via dock power button when a thunderbolt or display port output is hooked up to an external screen - however boots up fine in this scenario with only VGA connected. Always boots up fine though with thunderbolt, display port and VGA connected and lid being open 🙂. I presume I can't run dgpu mode only (or hybrid graphics disabled, as the setting is called in bios) anyway, therfore I won't try 😜, as this would end up in a black screen also. Whether I have the setting on automatic or hybrid graphics enabled does not make a difference with this behaviour.

    Thanks JadeRover for expanding in more precise detail. Of course I was aware of the MUX business when I wrote "don't know how this works exactly". What I meant was that e.g. I am not aware of the lanes bottleneck. What I understood thus far is that the igpu in the zbook 17 G1/2 can't drive a 10-bit panel. One rather curious thing I found with this RTX3000 version of mine (presumed as ADLINK as I mentioned, bought in 04/2025) is that you cannot switch on the laptop on the docking station with the lid closed and any display port or thunderbolt port output connected to an external screen, maybe also VGA, not sure atm. - no matter directly on the laptop, or on the dock - because this will cause the UEFI/Bios to lock up, or "fail to post" for a lack of a better expression. It does post just fine however connected to dock and nothing connected, or when switching it on with external outputs connected and the lid open. Probably some handshake going awry somewhere... I think I could easily solve this be removing the lid switch magnet from the display bezel, but for the moment I am not too bothered by this to actually test out this theory... Edit: curiousity got the better of me, I checked and it works with lid closed and VGA only hooked up.

    Great, dunno know whether HP RTX3000 would run in the 17 G1 though with a 3rd party DC. The thing is, the standard, non-DC Zbook uses an LVDS screen, and also the DC is LVDS I believe. I don't know how this works exactly, but apparently the igpu puts out the video signal through the display cable, which connects onto this board, and it is then converted to LVDS via this board below the screen. HP for ZBook 17 G1, 17 G2, LVDS Board (PN: 741282-001, LS-9374P) - 2630138 The ZBook DC screen converts edp to LVDS too with an internal controller board behind the panel. Dunno why, it's just a weird design to me. Edit: apparently it would run:

    Yeah, and I got my running just fine, thanks 😉 My machine is a zbook 17. The RTX3000 displays through the integrated GPU. That's why I have to keep hybrid graphics enabled in bios. Otherwise it will create a black screen. And that's the reason why the RTX3000 can't be used in combination with a dreamcolor screen, as the DC will automatically disable the igpu.

    That is an actual picture of my RTX3000 from the ebay listing I got it from, with its heatsink mounted ofc. Was advertised as "NVIDIA Embedded MXM GPU Module with NVIDIA® Quadro® Embedded RTX3000 Mobile". Won it for 120 sth. €. HP ZBook 17 Compal LA-9371P Rev 0.3 Schematics.pdf

    I have no idea what that means :-). I actually have a rtx3000 in my primary zbook 17. I think it's Adlink

    I eventually put it in my second zbook 17 g1, which is currently running a crappy K610M. I'll probably drop the M4000M into this one, and maybe sell the 8760w with k3100m inside.
  9. loopster
    Both are LVDS and on 460.89.

    I found that versions somewhere later than Dec. 2020 seem to break brightness control on my 8570w with M1000M and 8760w with M4000M. In each case I simply took the latest version from https://www.nv-drivers.eu/ for the respective cards listed and brightness control works flawlessly with those versions. I believe they are both on 460.89 (can't check right now to be sure). Never bothered to check what the latest functional one actually is. For the M2200 it would be the same version.

    Denatured alcohol to clean off the sticky goo on top, then use a few drops of baby oil (yes, baby oil 🙂, it works best) to give the surface a fresh finish and seal it off.
  12. loopster
    Would you be so kind as to share this 100w version of the p3000m bios here? I'm tempted to give it a try on ZBook 17 G1. Would it work 🙂?
  13. loopster
    I've got a Dreamcolor display assembly from a parted out HP ZBook 17 G2 here. Does anyone know whether the panel of this assembly can be integrated into a Elitebook 8760w as a straightforward swap? The 8760w is running a M4000M. I can't use the Dreamcolor display on the Zbook 17 with RTX3000 (or P3000 for that matter) as I understand, as the RTX3000 card needs Hybrid graphics enabled in this model, which in turn would automatically be disabled with a DC display.

    Which GPU-Bios does your card have (you can check and dump it with GPU-Z)? Maybe you should consider flashing a different version?
  15. loopster
    Maybe the previous owner mucked up the card with a modded bios?
  16. loopster
    Bios corruption seems very unlikely to me. For a quick check, you could always try a popular linux distro in live or as an install (maybe even switching nouveau to nvidia drivers). ... or a different Bios Quadro_M2000M_82.07.9B.00.02-HP.ROM Quadro_M2000M_82.07.8F.00.1B-Dell.ROM

    Have you tried inf-modding with this? https://www.techpowerup.com/download/techpowerup-nvcleanstall/

    I've got an ADLINK RTX 3000 running in a Zbook 17 G1 with hybrid graphics enabled. Would this mod allow the card to display in hybrid graphics disabled-mode? I wonder what the performance difference would be...?

    Long screw damage?

    For your power limitiations, I don't know whether 230W HP blue tip adapters exist, but you coud try a standard 230W from a let's say 8770w and convert it with a 7.4 mm to 4.5 mm dongle such as this one: https://www.amazon.com/Converter-Adapter-Pavilion-Elitebook-Chromebook/dp/B089593FB2?th=1 or this: https://de.aliexpress.com/item/1005005075356843.html They generally do the job just fine.

    The T2000 you linked is not an MXM card. I'd be quite amazed if he got that one running 🙂
  23. loopster
    Never had a zbook 15 g2, so I am not speaking from experience, but I have no reason to believe that it wouldn't work. zbook 15 and 17 g1/g2 have been proven to accept anything up to turing gen cards.

    That's a great turn of events. I just came here to express my condolences, and now there's no funeral at all 🙂 Your initial announcement scared me so much that upon reading it, I rechecked and replaced the thermal pads on the VRMs of my freshly built-in RTX 3000 (upgraded from P3000 in ZBOOK 17 G1) with thicker ones yesterday evening. You wrote earlier that your VRMs were overheating during early testing. How did you notice or figure that out?
  25. loopster
    Possible, but in any case you need additional conversion hardware to adapt ftom lvds to edp, dreamcolor or a custom-made solution. I doubt it's worth the effort if you don't know what you're doing and where to source parts etc.
