    Well, this custom coreboot need more polish, but seems it works !

    Hi, in fact I did same, bought BB09 not holding charge. I had to wake it up using original HP charger (you have AC input on battery, so you don't need to connect to laptop to charge it). It held charge for almost hour, but near 10% backlight started flickering - meaning battery needs new blood li-ion cells. I discarded guts of that slice battery and made it laptop stand so I can use it laying on carpet or bed. I think yours need longer time on HP charger

    I use DC screen, meaning it's LVDS driven by EDP-to-LVDS board. That board is connected by EDP from mobo. On mobo there is 50 pin connector, housing both LVDS and EDP signals. Which one are used is determined by GPU used. About project I think that CPU is defective, every RAM I tested threw error in memtest, meaning RAM controller in CPU is shot. And I don't see any good CPU for sale, even on marketplace....

    I don't think it is worth with such old CPU. It compiled shaders for Monster Hunter Wilds for 6 hours (first start). Right now I have faulty RAM sticks to troubleshoot and I'm getting tired. 1. Yes 2. Yes, I planted DC screen from 8560W to mine 8570W. 3.Never used Mxx cards, but in that case I would use external monitor untill installing drivers.

    Pretty simple, test using game/program taking between 90 to 100% usage of GPU, check GPU core temp with Msi Afterburner and if core temp is lower than 90 celsius, any sudden shutdown means power delivery overheat. Not all GPUs, especially those in laptop, lets you check those. I checked height of original heatsink and compared that to mine.

    It was windows update that corrupted my me region along with bios .... I used windows 10 ssd for using nvflashk for vBIOS flash (it was faster than learning how to do same in ubuntu), used it for like 4 minutes, after successful flash I restarted... "WAIT FOR UPDATES BEING DONE" During those few seconds before I pull plug, it made so much destruction. I had to use different flash chip and search for original bios dump!! ME region destroyed laptop entered manufacture mode! And I used Windows Update blocker on that drive (it was "emergency safe win10" external ssd). Now it is working again. But let it be warning for everyone =] TL;DR - using Win10 for vBIOS flash broke my laptop BIOS. GPU is fine

    Tried different distros, finally stayed on one seemed most known to me (I had experience since version 8.04 was considered new). I always had given up on learning and using it as daily driver, now I sometimes have some problems, but lefty loosy - righty tighty and still not going back anymore to Windows.. especially after last 3 buggy reinstalls in 2 weeks.. EDIT: It is Ubuntu, 24.10 And Arch also known as SteamOS on my SD.

    It could be sign of not compatible GPU core temperature sensor. Laptop enters panic mode, fans goes with max speed and turns off after minute. There was one guy, to whom I sold my P5200, that described problem (here on forum) and solved it. Then P5200 worked flawless with his Clevo. You have to look for throttle reason (in Throttle stop) and I suspect it could be power limit (because of not compatible temp sensor). PCI gen 2 wouldn't limit wattage given to GPU

    Nice mod ! I modded my Eee PC a little too, it ran everything I threw at it, every retro game from DOS to Win 98 era. It was 900 series model.

    As good as it can get now, benchmarks after "another patch":

    True, best and very costly way, I got quoted almost 150$ for one ! And then is even bigger problem, heatpipes. It wasnt possible for me to set them up like I imagined. That is because of laptop non-negotiable dimensions like battery or RAM slots. Sadly. I circled two troublesome VRM's protrusions, depth for coil cooling is also different Now hardest part comes - to solder it. And if works like intended - paint job.
  12. GuitarG
    Thanks ! Still ironing heatsink out, I forgot about different thermal pads dimensions. It shame I don't have some nice CNC machine. I played for a while and temps were up to 90C turbo CPU and GPU 70-80C depending on load. VRM or VRAM overheated once after 30 minutes, so I'm making corrections What PCB do you have in mind ? If first photo, it is donor board+case cutted up for aligning heatsink with highest homemade precision 🙂 I use damaged CPU and GPU board, screw heatsink on and clamp heatpipes.
  13. GuitarG
    Secret for success is to align first, then push harder second time. After baking like this first, then its screwed harder and heatsink only for max efficiency Now time for final tests, touch and black paint

    I have same model & revision, so that one seems more safe choice. Differences are much more stable behavior, hardware bugs fixed. Using my P5200 as example, in rev A that card would burn its power delivery if used with +90W bios. With rev D it could use 110W for long time with no problem. Model and revision says about board, not core used. It is true about perfomance loss in SG, up to 15%. For that alienware it seems you may have two options: 1. two board versions, one for edp other for lvds 2. one board version using single connector and two different lcd cables (like my HP). With eDP you would have much more LCD panels to choose from (LVDS is on its last breath). DP signals are different than embededd DP, eDP drives with PWM internal LCD brightness, use of closed-lid hall effect swtich for turning it off when closed, most important ones.
