Just a heads up, the Intel BE200 Wifi 7 card from China works fine in my M6800 under W11. + The model is "BE200HMW".

WTB Dell Precision M6700 lid / top cover. Just the lid without hinges or screen etc is fine. Must be without scratches or dents (!). EU only.

SATA caddy installed, works like a charm. Also replaced the CPU with 4940XM for the sake of 'maxing it out'. I've been reading it's possible to mod the UEFI to OC the CPU? With PTM7950 there is a bit of OC headroom. Need to think about the GPU as the K4100M is a rather poor performer despite it's 4GB VRAM and running a +135 / +200 OC in Afterburner.

Thankfully it's not destructive ed. it will still work for Keplers. The middle part at the bottom where it touches the row of black capacitors needs to be sanded down from the right as on Maxwell the coil has a different placement. This part needs to be removed: It's all soft aluminum and copper and done if a few minutes though. By the way, does anyone still have modded BIOSes for the M6800?

Well, the card is confirmed defective. Tested in a Dell Precision to identical result - hard shutdown under load, triggering the OCP and shutting down the power adapter too. Will post a few pics in a while. There aren't any discolorations on the PCB by the way.

I also had the luck to buy an orange M6500 Covet with 920XM (have a 940 on the way), 16 gigs of RAM and an FX3800M. Does anyone know which driver for the 3800M works in Windows 11? I get a black screen after reboot after I let it install the Nv driver through Windows update. Works fine in XP though.

Thanks, I bought a SATA caddy. Removing the front trim/bezel of the old DVD drive looks like a challenge, the 12.5mm ones on my HP's were much easier to remove. For CD/DVD drive I have an iODD ST400 emulator.

Sadly the DVD drive is shot on my 6800. Is it just a standard 9.5mm drive or do they have a vendor lock?

I also noticed the 6800 has the same problem as the 6700 with the retention clip of the keyboard connector breaking, probably because of the heat from the GPU.

Hehe, my Covet M6800 doesn't even have an eDP connector, only LVDS. Internal layout is completely different from M6700.

What about the touchscreen model, same? I assumed it was the RGB LED IPS.

Does the M6800 Covet come with the best screen available for these? Is it the 3D screen?

Could it be Windows is the problem? I have an AMD firepro model of the 6700 as well but that one doesn't show the Intel iGPU either in W11. + Ok, got Optimus working. It must've disabled itself in the BIOS after swapping the cards. Now I just need a WinXP driver for that M5000M and everything is golden... Done so far: - Replace CPU with 3940XM - Upgrade RAM to 1866MHz 32GB - Upgrade GPU from K4000M 4GB to M5000M 8GB - Replaced all thermal pads with Arctic TP, TIM with PTM7950 - Upgraded storage to 860PRO 2TB for all OS'es, 870EVO 1TB for general data, ISO's etc - Added Intel AX210 WiFi 6 card from Aliexpress, moves the N6235 to other slot, that way I can have normal WiFi in XP and WiFi6 in W10/11 (AX have no XP/7 driver). Things left to do for my M6700: - Find the upgraded palmrest with fingerprint and NFC reader - Find an undamaged screen bezel w. webcam - Upgrade screen to eDP IPS, keep 1080p but with higher Hz to match or exceed the Covet panel. Or maybe there are better panels that are a drop-in replacement on LVDS? Option: - Find 4x8GB 2133MHz RAM ++++ Ok, I got the M5000M working in Windows XP! I downloaded this driver: https://www.philscomputerlab.com/modified-nvidia-drivers.html Added ID 13F8 and it installed perfectly. Under XP the card is being seen as having 4GB VRAM but that's probably an XP limitation. Optimus remains a mystery, after using XP and rebooting to W11 the Optimus was disabled again and Intel HD graphics not visible in device manager. The GPU performance in XP is a bit worse than in later OS'es, tested in 3DM06.

I used NVcleaninstall, picked the first M5000M template from the list, added 13F8 HW ID but no cigar, I don't even see the Intel GPU in device manager.

Not sure if it's just me but M5000M doesn't support Optimus??
