    you may need to discharge it properly, sounds like a static issue.

    Take out power and battery, hold power button for 30 seconds, then remove the tiny silver button battery from under the keyboard and leave it overnight.

    It might reset your board, it might not, but it's worked for me in the past.

    I tried the SIIG Card it does not work. It does not recognize g-raid mini or Lacie Rugged. Nothing I connect to it works. This is the second card in two weeks. Please tell me what I am doing wrong.

    I'm struggling with the keyboard on my 8760w. The last couple of months the keyboard is getting "unprecise", missing a "type" here and there. It feels like its helping if i really hammer the keys, but that's no good. I did remove the keyboard when I added RAM, could there be some bad connection between the keyboard and system or something?

    Project: Create the most graphics extreme HP 8760w desktop replacement on the planet.

    Upgrade my HP 8760w FirePro M5950 graphics to the extreme NVIDIA GeForce GTX 680M (4GB-DDR5) with 1,344 CUDA compute cores.

    I would like to significantly increase the graphics capacity of my 8760w laptop for DirectX11/CUDA/OpenGL for specialized "computing architecture/art" applications and rendering. The standard 8760w graphic boards available from HP are NVIDIA 4000M & 5010M and are priced between $2,500-$4,000 just for the graphic board. If my ATI graphic board died, HP replacement part is only $250 which shows how low-end it is. Switching the graphics fan version from ATI to NVIDIA is only $48.00 from HP.

    It is my understanding that the 8760w uses the "MXM 3.0b" graphics module form factor and cooling standard. Aside from swapping the fan out, I should be able to put into my 8760w laptop any MXM 3.0b standard graphics board. A MXM 3.0b standard NVIDIA GeForce GTX 680M, 4GB RAM and 1,344 CUDA cores graphic board only costs about $800 new, $600 refurbished. Twice the compute power over the HP supplied 4000M/5010M at 1/5th the price. Labor not included. :)

    With the GeForce chip being a standard gaming chip, I am sure it would also be recognized and supported by any video game at the highest level FPS/performance.

    Passmark Video Benchmarks for these video chips (higher is better)
    HP standard graphic board options for 8760w:
    FirePro M5950 (1GB RAM): Benchmark - 1,257
    NVIDIA Quadro 3000M (2GB): Benchmark - 1,214
    NVIDIA Quadro 4000M (2GB): Benchmark - 1,608
    NVIDIA Quadro 5010M (4GB ECC): Benchmark - 1,383

    versus:
    NVIDIA GeForce GTX 680M (4GB): Benchmark - 2,637

    HP wants $4,077.00 for the Quadro 5010M (MXM3.0b) graphics board upgrade. A new GTX 680M MXM3.0b is $800.00.

    Questions:
    Anyone ever replaced their 8760w graphics board with something other than the HP options?
    Does the 8760w BIOS have a restricted hardware white list? Has anyone unlocked the BIOS used on the 8760w?
    Heat could be an issue (especially if I sometimes overclock the 680M). I have to assume the standard Quadro 5010 generates quite a bit of heat. Any graphics cooling advice here? Is there software that can provide greater control over the 8760w fan (e.g. during GPU overclocking)?
    Any thing else I need to consider besides violating my warranty/service contract?

    Without really knowing for sure, I guess that the HP BIOS restricts you from fitting a Keplar based Nvidia board on the 8760w. Just as it is the BIOS that restrict the RAM from running at 1600MHz despite the chipset supports it. To be honest, I'm curious myself if it is possible but pessimistic at the same time.

    Done. September 12th, 2012, 6:20PM (PST).

    The world's first HP 8760w with graphics powered by NVIDIA GeForce GTX 680M (4GB-DDR5 / 1,344 CUDA cores).

    Summary Notes:
    No HP BIOS mod needed (nor would it have been possible because it is RSA cert. signed.)
    Uses the HP 100W rated heat sink/cooling solution used for HP option NVIDIA Quadro 5010M card.
    Very safe max. GPU temps leveled off at 90C during ten minutes at 100% GPU stress test. (my biggest worry, after possible encrypted BIOS).
    HP BIOS fan tables variably incremented up fan speed as GPU temps were rising to max 90C temp and max fan speed. (ie. integrated with GPU temps).
    Tools: you need Torx T8, plus small and very small Phillips screw drivers.
    GPU swap in Elitebook very easy compared to consumer-class notebooks.
    GPU replacement guide: Used "HP EliteBook 8760w - Maintenance and Service Guide" PDF from HP website.

    Nvidia 680M in HP 8760w/i7-2630QM/8GB Benchmark:
    Furmark Stress Benchmark:
    AMD 5950M ran at 4FPS (100% GPU)
    NVIDIA 680M ran at 34FPS (100% GPU)

    AMD 5950M 3DMark06 Score: 11,085
    NVIDIA 680M 3DMark06 Score: 18,435*

    *I feel like this score should be higher but I can't justify why yet other than the 3DMark06 benchmark being too outdated for Intel Sandy Bridge/NVIDIA Kepler architectures. I know the GTX 680M(mobile) vs regular GTX 680 does thottle down and up. CPU score was low too. Max temps imply room to safely overclock.


    Parts:
    680M-4GB MXM3.0b graphics card, $800.00-USD. (Purchased from Eurocom*)
    NVIDIA fan/heat sink assembly (includes thermal paste). $48.00, HP Part# 652544-001 - (used by standard HP NVIDIA Quadro 5010M option)

    *Eurocom. I've read the complaints. They exceeded my expectations. How many first-call tech support groups can you call and they can give you the Thermal Design Power details of a hardware component?

    Oh wow, this is incredibly impressive. Do you reckon this could work with other MXM 3.0b video cards as well, such as the 675m? How would you change the driver ini file appropriately, I don't quite understand how you found the HP values.

    Yes, I do believe all NVIDIA MXM3.0b graphic cards would work along with the HP NVIDIA heat sink component.

    The HP Vendor ID (103C), HP laptop model ID(1630) can be found by using device manager to open "Hardware ID" in the drop down list box for the device property. NVIDIA card model ID (1212=675M, 11A0=680M) can be found by looking the driver file.

    I am not sure about other MXM3.0b graphic card vendors. I did dump apart the 8760w HP (Insyde) BIOS into the 980 individual ROM files and scanned them for the ROM's dealing with the graphics cards. I put just enough effort into it to learn that HP created their own proprietary "whitelist" scheme that wasn't provided to them by BIOS vendor Insyde. HP then encrypted it with a RSA cert making a BIOS mod close to impossible without constant BIOS failure problems. They apparently are not restricting NVIDIA cards but they definitely have some proprietary code that is referencing just ATI and NVIDIA graphics cards and no other vendors. The BIOS looks like swapping wireless cards is likely whitelisted to certain manufacturers as well.

    For the 675M, here would be the driver file edits:

    Thanks for the explanation. I think you've put down the wrong part number in your first post though. Looking at the service manual the correct number is 652544-001 and not 652543-001.

    Fan/graphics board heat sink assembly (includes replacement thermal material):
    For use with ATI graphics subsystem 652543-001
    For use with NVIDIA graphics subsystem 652544-001

    Benchmark Summary for Nvidia 680M-4GB ("Kepler") in 8760w/i7-2630QM

    System specs:
    HP 8760w, i7-2630QM, 8GB, 1TB (2x500GB-RAID0), Nvidia GeForce GTX 680M-4GB "Kepler"
    Nvidia Driver Version: 306.23

    Furmark Stress Benchmark (1280x720):
    ATI 5950M: 3 FPS
    Nvidia 680M: 43 FPS

    3DMark06 Benchmark:
    ATI 5950M: 11,085
    Nvidia 680M (Stock): 18,435
    Nvidia 680M (O-Clocked): 19,026

    3DMark11 Benchmarks:
    Nvidia 680M (Stock): 5,696 (P)
    Nvidia 680M (O-Clocked): 6,591 (P)

    Nvidia 680M (Stock): 5756 Graphics Score
    Nvidia 680M (O-Clocked): 6,856 Graphics Score

    Nvidia 680M (Stock): 6,223 Physics Score
    Nvidia 680M (O-Clocked): 6,238 Physics Score

    Nvidia 680M (Stock): 4,727 Combined CPU-GPU Score
    Nvidia 680M (O-Clocked): 5,471 Combined CPU-GPUScore

    Over-Clocked Settings:
    GPU Clock: 854 MHz (VBIOS max.)
    GPU RAM Clock: 2,280 MHz (Capable of higher clock but appears ECC RAM causes memory error rate increases, slowing performance.)

    Extreme-Over-Clock Settings:
    VBIOS firmware flash mod required to remove GPU OC upper-limit of 854 MHz.
    GPU Clock: 1050 MHz (best guess from Clevo-680M users)
    GPU RAM Clock: 2400 MHz (best guess from Clevo-680M users)
    3DMark11 (projected): 7,500 (up from OC value of 6,600)

    Upgrading CPU from 2630QM to i7-2920XM/2960XM might add another 5-8% to benchmark scores.
