    RIP my P870KM1?

    So I got my KM1 from HIDEvolution in 2017 and it has been my workhorse ever since. Unfortunately yesterday it decided to freeze and now won’t power on. What is interesting is that on battery it won’t Post and will turn off after 4-5 seconds (screen doesn’t even light up. When I remove the battery and leave it on charger it will stay on indefinitely but still not POST. In both scenarios fans do not kick in when I turn the laptop on. Have already tried the hardest NVRAM reset I could muster and have done everything barring removing the vapor chamber.

    Any idea on what the issue could be? I will have to call up HIDEvolution Monday as I love this laptop and need it for other stuff.

    Edit: guess I should tag @Mr. Fox and @Spartan@HIDevolution just in case.

    Could be component failure, I would try and test the cpu in a different system if possible and then work down the list of components.

    Darn I don’t have spare stuff to test with. I do hope it’s a mono issue and not let’s say the GPU.

    Do any of the heatsinks get hot?

    They don’t now that I think about it. When testing without battery they don’t get hot

    LGP7lCS.jpg Okay here’s an update, I finally got around to popping out that vapor chamber and reseated the cpu and gpu. Now on battery I get fan spin before it turns off. Here’s what I have under the hood, hope it helps.

    [​IMG]

    No CPU no GPU = no fan spin then off
    CPU only = no fan spin then off
    Add the GPU = fan spin then off

    Sounds to me like a dead GPU but try to find someone with an MXM gpu to pop in there for a few seconds until you have image on screen to confirm. Any Nvidia MXM later than Fermi should work to boot. Where are you from?

    Try popping the GPU out and see if the CPU gets warm when you start it out.

    And if the CPU gets warm:
    1. you can then pop gpu back and see if that gets warm
    2. if gpu gets warm. (even dough GPU die still can be dead)
    3. take out ram from laptop and try to boot with only 1 stick in different slots
    4. program a stock bios with programer
    5. Only then consider that mobo or/and something else might be dead.

    CPU is as cold as ice. Only GPU gets warm.

    update: forget I said that both get warm

    There you have it, try with another CPU. Any 6th/7th i3, i5, i7 will work.

    Go to any repair shop and ask them if you could pop another CPU in there for testing.

    shoot meant to edit my post fast. So the CPU gets warm and so does the GPU. Only difference is that the fans kick in only when both are plugged in. I do get the 2 second high speed fan whirr though for both

    Like I said before.
    Find and test with another CPU and another GPU and if all fails, probably you have a dead mobo.

    Now to find an mxm...

    Don’t know if this helps but removing the vapor chamber seems to allow the fans to spin. When I reapply it they sometimes don’t work.

    One of the right shape, a 1060 is the lowest easy card to fit.

    Sadly don't know anyone next to me with a spare GPU. Gonna send it to HIDEvolution and pray that it's the mobo that's bad.

    Random question:

    Was able to get someone to let me borrow their eGPU enclosure, could I try POSTing with that? I do have a Fermi card (gt 630) i can use on it.

    You can try certainly, the system may panic and shut down after a little bit due to no GPU signal from the internal slot but it's not going to hurt.

    Jeez does the laptop really care about that mxm slot? As long as it posts I’m fine. Though that feeling will end with the cost of a 1080 mxm

    Yes, because it assumes no signal = bad and something is wrong.

    Just shipped it out, couldn't get the eGPU working (might need a stronger power supply). Will let you know how revivable the laptop is.

    I was using a 60W one as I only had cheap OEM video cards. The 120w just came in the mail so I’ll have to try it on my tablet. The EGPU I use is the Atto Thunderlink.

    Also HID called me up and figured out it was the Mobo. Bullet dodged on that GPU shyt. If you have any 8th/9th gen CPUs lying around I might take that off your hands. Need to sate my dependency on the latest Windows.

    Similar TDP to 7700K, wanna part with it when I get my comp back? Looking for one where I don't have to mod the heatsink if possible.

    It's a nice sample, mine ran 5Ghz on a dynamic voltage -100mV offset but that was with a custom lid that kind of died when I tried to mod it for my existing chip. But it can run a lot cooler at say 4.7Ghz and still give most of the performance and be efficient.

    Let me know if you are interested with a message.

    Based on your message to me I would say focus would be on the GPU next, do they have one to test in it?

    So just got an update it turns out that the CPU was also dead as a door nail. Can 6700ks work in z270 boards? Otherwise I may have to source another 7700k.
