    So I completely disassembled the mech15, and it turns out, it has a 40 display interface, which means if I get the right cord, it should be able to take a 144hz panel, which is solely 40 pinned. All pics are at bottom of page with link

    My concern with doing that is that same 40 pin port also is being occupied in use with the microphone and webcam, and interestingly enough, there is another port next to the 40 clamping port of the same type, though I am unsure of the name. If any of you know the name of the cable please tell me. Otherwise I think these two item will get the 144hz panel to work.

    https://www.ebay.com/itm/10-1-14-15...Cable-40-Pin-Extension-Connector/272260521779 - cable isnt long enough, so this will be necessary.

    https://www.ebay.com/itm/New-Lenovo...DS-EDP-Cable-00NY456-Touch-Model/282071717067 - took awhile to find, but I think this is the correctly fitting one.

    This is all experimental, fingers crossed.

    So why not ask eluktronics? It would void warranty, and I can tell you they probably dont even know.

    My Pictures are to big for NBR, so here are the originals from a onedrive link anyone can view.

    Mine has a dell display and it’s 30 pin. I put a 120hz panel in with brightness control intact.

    I love that you’re going LM on this. I have been considering doing the same lately.

    Doing LM made it cool far better, in most games I never go over 65c, and under 100% cpu and gpu load, it never goes past 85c for cpu and 77c for gpu. I have yet to even undervolt them.

    I know it has a 30 pin display cable by default, but its using a sort of 40 to 30 pin adapter and the other part of the cable is used as an interface for the webcam and mic.

    Right on! Is this with maximum fan profile engaged? I know this is a bastard to tear down. Any advice or warnings before I proceed with this?

    max fan? Nope, just stock fan settings :p

    I recommend watching this video first, make sure you get ALL THE SCREWS! and in particular the place where the orange plastic piece is hiding in the video.



    Something to make things easier then what Bill Love did, do not attempt to remove the film cables from within when he reaches inside, thats a very difficult way of doing what he is doing, and there is a simpler method: When you release the 2.5inch drive, there is a layer of black plastic. Remove it, and then unhook the two film cables by lifting up the black clamps. remember where that blue foam piece is at as well, I dont know what piece that cools. Also, I will update my pics sometime which will make all of what I am saying easier. Also, just about all of the film cable inputs are clamp mechanism, and only one or two of them isn't, you'll figure that out, just dont push it.

    If you do a repaste, make sure all the Pads are in the correct place first! If you mount it wrong just slightly, thats enough to move off a piece and hence no cooling for that part, and just keep taking it on and off till your confident you got it right, but on and off with LM applied. Also, remove the pads on top connecting the cpu and gpu and replace them with some thermal paste instead. The pad thickness does inherantly make the cpu hotter and mount unevenly becaues it lifts up the cpu part of the heatsink the left side where the cores are.

    Haha, im glad you showed the part where you lift up the black film under the drive, I never did that, and it screwed me up initially.

    The only thing I really think you should have done is take apart the heatsink with the 4 screws labeled 4 through 7, and remove the pad and replace with a little grizzly. The reason for that is that it will seat more evenly on the CPU, where as the pads actually lift up part of the cpu as I found in mounting and dismounting. I hope you got the sink on correctly because I had relifted my sink up only to find that a pad accidentally over laped on the VRM's because I had not mounted as carefully as I should have. If you so chose to again to check and put LM on the gpu, the heatsink does come apart as I said earlier. Its easier to take off and put back one piece at a time then the whole thing

    What I dont get is why yours didnt have a thick thermal pad on the lower corner of the board for a chip piece like mine does. Im not sure what that even cools, but it was there for me.

    Im glad yours at least started up, apparently the M2s can actually mount slightly off on the 5 lanes if you look carefully. Mine wouldnt even boot out of safe mode for that reason, and the display wouldnt work, but either aligning that or the restore got mine back running. it could have also been that I had not fully inserted the EDP port to the panel, hard to say.

    Show me what temps your getting in stock settings, I would like to compare. I meant to say earlier that my temps would not go past 65c if I was doing only the cpu, but it with the gpu raised it of course to the 85c and 77c amount.

    Pre LM the GPU would hit in the mid 70's at the most running 1886mhz and the CPU in the mid 80's uncapped playing Blackout while live streaming with OBS. Max fan speed.

    From what little I have tested so far, CPU temps dropped 10c.

    Came back together issue free and booted no problem. As I type it's silent. I love it but I cannot recommend the job to most.

    I was thinking about it for weeks and this post pushed me over the edge to just get it done.

    Thank you!

    Hey your welcome

    if your interested, I can tell you a few easy mods to increase air flow, but that involve opening it up again, but it beats the max fans as this does increase air flow by about 30 to 40 percent.

    Im curious though, what have your thermals been so far? in most games I run, I usually never go past midm 60s, but the gpu will hover around 77c in demanding gpu apps. In the most extreme cpu and gpu combo benches, I cracked 86c on stock voltage for cpu and 81c gpu, but it would not didnt sustain it because the next highest fan setting would turn on and lower them both and then turn back to the lower setting once the cpu was below 84c again.

    For me, the LM lowered the GPU a good 7c in the most demanding applications like above, and the cpu 10c like what your seeing.

    If you dont mind, im curious to know what your undervolt settings are. I havent messed with that yet out of fear, but you might just be my tipping point :)
