    In my work as notebook repair technician I use brush and compressed air, brush keys from everyside and use air simultaneously. If it is really really dirty I use glass cleaner 50:50 mixed with izopropyl alcohol and VERY VERY carefuly clean keyboard taking just little bit of mixture. That way is only for your own responsibility, but I find it cleans gunk and wet dirt very nicely. Sometimes I even pry out keys,but that is very dangerous for key mechanism. I recommend only first one, cheers!

    That's fascinating work ! I wondered about using Zbook 15 G2, but I find aesthetics somewhat ugly because of that lid design - half plastic half aluminium. However, that model is especially interesting because of LCD - it doesn't have dreamcolor option and LCD is pure 30 pin EDP. That means you should be able to use Pascal and newer GPU without problem. Does it work on hybrid or dGPU only mode ? I tested non dreamcolor zbook 17 g2 and it worked only in hybrid mode. HP states 17 G2 DC screen works in only dGPU mode. And what about fan control, there is no problem with that ? For GTX 980 fan control was as from factory, but with Quadro P5200 I have to use Notebook Fan Control program to control fan. I'm thinking about combining elitebook 8570w case with zbook 15 g2 internals. Advantages ? I can undervolt 4th gen Intel CPU, 3 USB 3.0 instead of only 2, thunderbolt connector.

    Alright, got some free time, I can now show other steps ! I am this kind of man, that can't stop trying to make thing better and better. I had redone whole heat sink using damaged lower mountint case, damaged motherboard, damaged full height mxm card and damaged procesor as "mold" to get as close as you can get to make space between CPU/GPU silicon and copper block of heatsink. After baking in 140 degrees celsius using solder paste RL-404 (138C melting point, very important as to not get heatpipes damaged) I had to do it one more time. Because I forgot to put good pressure on heatsink touching copper pads so it didn't worked as it should. I also used grit paper together with polishing paste to make copper shiny like mirror so it conducts heat better. It fits like original heatsink now! Yay! Then I though of problematic fan. Because of its blades geometry, it took more from hot keyboard than from cold air under notebook. In future I want to make it upside down like in newest notebook designs, for now I use fan from Zbook 15 - had to change cable order in fan plug. Zbook fan have much better geometry, takes more cold from down side. And queiter. Redesigned cables from additional fan - I made mistake, 5V cable got heated from heatpipe, desoldered and fried resistor next to fan plug. I was shocked laptop didn't shut down and I had only to replace one resistor. I took safer measures next time, routed cables on case using kapton tape, took 5V from DVD slot points and connected PWM to tacho of original fan - so additional one works as it should together with original. Last thing I had modified is those too small vent exhaust points - why upgrading with bigger heatsink, better design when it have too small holes to blow air through ? So I used mini rotary tool, put a little of epoxy between magnesium and plastic frame so it holds firmer. Holy cow, I didn't expect that much improvement. Only thing that left to do is make whole heatsink in 3D model, order fully copper CNC-ed mounting blocks for CPU and GPU (unfortunately custom vapour chamber is unorderable) so heat mass is bigger, turn original fan so it takes more air from under notebook.. We shall see, because right now I am very happy. I could only be happier, if P5200 would be correctly recognized by thermals, but software Notebook fan control is not bad either. I also spotted some kind of problem when I try to boot linux.. It is not possible at all. Tried from ubuntu to arch linux and none of them even booted in live cd mode. They just boot, give me menu option and that's all. I wonder if it is because of not compatible GPU - like in windows we can use NvClean so it works. I recommend this kind of modding to everyone, because it is so much fun! And satisfactory because I can play newest games with no problem at all in 1080p. As usual, ask any questions, I will try help and share my knowledge. I'm thinking about making YT video from gameplays, how it behaves, etc. One day maybe I will get my hands on RTX mxm card.. I would be super happy, haha Cheers!

    I am thinking about buying Fury G9, anyone tried playing games on it ? Is it worth to go for Quadro RTX A4500/ A5500 version or A3000 is enough ?
  5. GuitarG
    Yes, GTX980 is rated between 80-120W of power, stock cooler for gpu only 50W. Card will throttle.
  6. GuitarG
    When I used GTX980 I had same problem, try to disable group policy for automatic update of drivers. Also you can try to use NVflash (I used "override certifications" version) and try other vbios. Mine card was G-Sync one, I used non-gsync bios from clevo or msi and it worked flawlessly. If you're not modding heatsink, try setting low power mode in drivers to not damage card. Thanks ! 🙂 Power supply was rated for 230W, it was enough for 120W of power used by card + 45W CPU and other components. I used it for a while with stock cooling and tried not to stress it too much. And when I used benchmarks, CPU temp was way worse - about 100 degrees. GPU was about 85-88. Safe temperature for GPU is about 85 degrees when using it for long time. For second fan I just used dremel tool to take out fan from HP 8770w and connected 5V and GND to nearby trace and PWM to Tacho on my main fan. Will show pictures later. For now... I couldn't stand damaged heatpipe from job before and had to make it all better =] Will explain later, for now... pictures!

    How that 3840XM is working ? Better and colder than i7 3740qm ? I'm wondering about upgrade. I also recommend changing wifi minipcie card to AX201. Nice one! Have you tried benchmarks like userbenchmark.com or firestrike / time spy ? I am curious about results !

    You should try out on external monitor first, try connecting monitor to display port for checking it works for sure. For changing to external monitor after logging in windows use Windows key + P and then click once arrow down then Enter. If VGA is not correctly working then you will hear fan going 100% from start. If VGA is working then fan should make one test turn and work accordingly to temperatures or go 100% after 10-15 seconds. I had also though about RTX Quadro, model 5000, but there is not even one on auction site in my location. Also full height cards have different mounting points. You can at least try, if you're careful you won't damage anything : ) It will be many times faster than those original mxm cards. After you're sure it works at all, then I can encourage you to look for other parts. EDIT.: You can find some information here

    Recently added second fan to cool vga heatsink. I used fan from 17' inch HP 8770w. Will show pictures later! Additional fan is controlled as original fan. There is already big improvement and I'm very happy : ). I have received Zbook 17 G2 recently with dreamcolor screen. Mine heatsink parts are mainly from zbook 15 because they are almost fully copper. I will test out them both how they compare in torture test with same graphics card.

    Thank you for your help ! I will try out Lenovo's flash, meanwhile I'm trying to pull out HP Zbook 17 G5 vbios for this graphic card. Lenovo and HP have their vbios hidden in uefi flash chip.. and in bios update. If It will work out, I will share it here. I have MSI vbios, when I will get back from work I will edit my post to add it : ) HP VR Backpack vbios and Dell works on mine mxm Rev. D P5200. Both have displayport and VGA output. VR Backpack don't have internal screen output. Mine is HP 8570w and I don't have muxxer or IGPU in mine - as for MSI 16 video output problem. EDIT: Adding zip archive with every vBios. Excluding : HP 86.04.84.00.39 86.04.a2.00.23 Fujitsu 86.04.8B.00.7E I still hope to have success obtaining them. Nvidia Quadro P5200 vBIOS collection.zip EDIT2.: With Mobile Pascal Tweaker and external programmer, you can edit MSI vbios to limit it 100w to try them out in your laptop if it works. That what I had done with mine, because this mxm card have limitation to 110W max. You can read it after you translate on this site: https://www.bilibili.com/read/cv10852330

    980m died 😭

    GuitarG replied to K4sum1's topic in HP

    Sorry for long time no writing. Those artifacts can be problem with video ram or main chip on that mxm board. You could check which one is problem by using hot air station or something similar. With hot air station you it directly above every video ram chip, one at time, check in system if there are still artifact, and go to next one until you find which one. 400 degrees celsius and 8 to 10 seconds is suffice. If GPU core is not problem then there is chance to repair this card : ) replacing one or two video ram is worth it. Replacing main core is totally not worth. Cheers EDIT. By checking video on VGA output or DP output you can be 70% more sure what's problem. In case of artifacts on every output, there is a big chance of vRAM problem. If this problem exist mostly on internal LCD - then main chip is 99% faulty.

    Values are in good range for this card, mine have similiar ones, so that shouldn't be power problem. But I will check inductor number 4 to be 100% sure, because this one is for GDDR power I think.. 24 ohms may be too small value for it. Give me few days I will check. Yes, you have correct heatsink for mxm 3.0b cards, original one for ATI M4000 is singlepiped mxm 3.0a. There are only two version for GPU and for CPU. Single heatpipe for dual cores and dual heatpipe for quadcores. Did you used some thermal pad for VRM and memory chips ? Also, if you could attach some HQ pictures of your GTX from both sides. Lastly, check how it behaves on VGA output or displayport only ! If screen will get frozen, click Caps Lock / Numlock and check if diode turn on/off. Cheers! EDIT. Check your vbios version with GPU-Z and driver version also please.

    You have to use hot air station and buy some mosfets - preferably 6 if you want to be perfectionist (I'm not sure what mosfets are used on your GTX). From my older thread: "Above two big inductors there's added 220nF capacitor, two other red circles are added 3 additional mosfets 87350D - one for every phase. " Mosfets you can buy; capacitor you can find on practically most laptop motherboards after Core 2 Duo era (220 is written on them). Check for correct position ofc and have fun : ) For standard 120W vBios it's more than enough - it makes VRM run more efficiently, stably and cooler.
  14. GuitarG
    It is not really a problem, those inductors we need to check are also very big You have to check with ohm measurement every coil on mxm board, one probe to coil and second to ground (for ex. mounting place for screws). Write those as numbered And by the way, can you show me what heatsink are you using ? I'm asking because your HP shipped with AMD card and there are 2 different ones for this laptop.

    I started similar thread back on notebookreview forum, but it was closed in few months. I would very like to share some knowledge with everyone. I remember there was one person that tried same thing, but I don't remember name of thread, nor I could find it. So.. For starters, my laptop is HP Elitebook 8570w. Very very long time ago I had bought 8770W, it's 17'3 inch big heavy laptop, I liked playing games on it but my back didn't like carrying it. I sold it.. and until recently, I bought 15'4 version of same laptop. But 8570w doesn't even pack a punch for older games. I though to myself, maybe buy some MSI or Alienware.. But.. I found auction of very cheap Gtx 980M, though "why not", repaired it, tried it with laptop... WORKED 😮 Then I found 8560w with Dreamcolor LCD. Gtx didn't liked that LCD, DC screen didn't liked that GPU either. But it started working together after flashing MSI vbios (no optimus) and using 389 version of nvidia driver. Pure UEFI and GPT is must. I made some mods like upgrading VRM of GTX and custom heatsink. But I wasn't that much proud of it like I'm proud of more recent work. I had bought Quadro P5200M very cheaply, it works charmingly with my HP, with only one thing not working - fan control. But I'm on way to fix it in few weeks. I think it have been incorrectly working programmer or not exactly fully compatible vbios. Problem is very clearly seen in HW Monitor: motherboard i2c SMBUS sensor for GPU is stuck at 85 degrees. CPU thermal diode and GPU's correctly show exact temperature of cores. But I think there is a conflict - wrong registers or something. I'm still waiting for better chip programmer to come. Specs: Intel i-7 3740QM Nvidia Quadro P5200M 16GB 120W 16GB DDR3L 1866 Mhz (4x4GB) Samsung Evo 870 1TB I made that HP work faster and better than his bigger brothers! Yay! Meanwhile, let me show you some pictures. You can also ask me directly and freely, I will try to help you out! And if you have some Quadro P5200 vbios, you can share : ) BTW, myths I though that are true.. 1. Weak CPU limits GPUs power. <--- Nope! When I checked with benchmarks, mine Quadro is as fast as those in original notebooks it cames from (ex. hp 17 zbook g5 or dell precision 7730). PCI Express have same speed, so.. myth busted! 2.NVMe SSD are waaaay faster <--- When I checked last time loading your game 6 seconds faster is not that much difference for everyday users. Maybe it is for ex. in movie editing. 3. No need to update dreamcolor edid for newest nvidia driver to work in 10 bit mode. I downloaded newest one and it works flawlessly. To be continued..

    Do you have multimeter ? I can help you. I know how you're feeling. I would never exchange mine 8570w for anything. I live from repairing notebooks, and let me tell you, our notebooks are far from being unusable or being worse than newer ones. Maybe in some special scenarios they may be slower.. otherwise as for normal users, they are beasts indeed. I used mine with Clevo GTX 980m, now I use Quadro P5200. I don't know where you from, but I though about selling it on this forum. Cheers!
  17. GuitarG
    Anybody ? Lenovo vbios ? MSI vbios ? Any vbios for this cool graphic card ? I have looked on 51nb and other forums, but I didn't found them. I already used those from techpowerup site..
  18. GuitarG
    Could you post them here please ? I also would like to try them out. (I'm trying different versions because of 100% fan all the time problem on my HP).
  19. GuitarG
    On techpowerup there are two HP 100w P5200 bios bin files that work. Both tested, both work. I used them with HP 8570w
