    Does anyone know the NAND type for the stock 256gb Phison ssd in the the OP 15+? I can't find any information on this drive after getting the part name from HWMonitor.

    Yes, the warm body is very normal. While gaming, try touch the area directly above F8 (left of the turbo button) , you may get a burning injury as it is usually above 60 degree. This is a compromise as the laptop is very thin and light.

    About optimization, don't bother. It gives you max 5% boost in performance and you probably need to spend hours and many attempts of trial-and-errors, and these optimization may not make the laptop last any longer. My suggestion is just leave it as it is.


    Probably can be done with a third party software, but I have never tried it.

    Hi i am new there but i have been the owner for over 6 month of a Mechrevo Z2 i5 business edition (which seems to be the same as a
    TONGFANG GK5CN5Z the generic brand name), however i am having a few issue with it:
    - first one, i cant seem to be able to make work consistently the nvme drive i added, most of the time it is recognized but then every so often it stops being accessible and i need to restart the computer and enter the bios to set again default value (same if not recognized at startup).
    So i would like to know what would be the recommended update to make that works consistently, i am currently on EC 1.24.09 bios 1.11. AFUWIN give me a firmware ID of GK5CNN111 and since i only found a GK5CNN102 here i didnt use it. (i linked the save i made of my bios here in case)
    - Second one, i am having trouble on old distributions of linux due to clock speed skew but since that was fixed in january 2019 in linux kernel, its not an issue anymore, and also it seems that changing the nvidia driver as well as switching them off with iommu=off or even acpi=off works, the mousepad situation is fixed on some distro but most of the time it still require fiddling. So far Arch linux is my best option but i would love to hear about guys that succeded to install a working GK5CN5Z with manjaro (working gpu, touchpad, screen zoom...)

    TLDR: -Any bios update for GK5CN5Z that fix nvme issue?
    - Manjaro users of GK5CN5Z ?

    Here the files i mentionned first is the rom saved with AFUWIN and the other the reg from intel CSME:

    Hi everyone !
    I own a GK5CN6Z from PC Specialist aka Recoil II, it did worked well until today when I updated the BIOS and EC firmware. Until this update I was using XMG BIOS 1.03 and EC 1.33.09 and I updated to BIOS 1.09 - EC 1.38.09.
    Everything worked well with the update, but when windows started I notice fans spinning way faster then usual and after monitoring the voltage and temps I notice an insane amount of VID on all the cores. Before the update voltage never gone over 1.250v under stress test and now it goes up to 1.420v booting in windows, and I'm scared it can kill the CPU. System shut down few times already and I saw thermal throttling too in XTU even with -0.130v undervolt. I didn't try to flash old EC (says is risky to downgrade in guide) but I did flash the old BIOS back but it does the same over-voltage. Resetting EC by taking out battery also didn't help.
    If the laptop is on battery the voltage is kinda ok, never goes over 1.150v but whenever I plug in the charger it goes crazy.
    If anyone knows who controls the VID (vcore), BIOS or EC firmware ?
    Is it really that risky to downgrade EC firmware ?
    Is it possible Windows screw up voltage too ?
    It really drives me crazy and any help would be appreciated !
    Thanks !

    EDIT : I fixed the issue by downgrading the BIOS again and fresh install for windows. One things for sure, I will never update BIOS or EC again since it's working anyway without issues

    Ok thanks for confirming. It seems installing programs heated up my PC, and it remained hot after that while doing light work only. I didn't experience such a hot chassis again in the past days while doing just light work. So seems if I'm going to do heavy work and want to do some extended typing after that, I better let it cool down a bit first to have a comfortable typing experience... guess that is a decent compromise for having such a light and compact laptop with this performance.

    As for the lightbar, that might be a fun project tor research in my spare time, getting the light bar to do more useful stuff than just indicatng on/off/sleep. The thing seems rather useless right now, since there are indicator lights for that purpose already...

    Also happy with the battery life considering the small battery. Before buying I thought I would want the battery upgrade that now seems to be impossible to get. But my experience so far is actually not bad. For light browsing and ms office work, battery is about 3-4 hours, which is entirely sufficient for getting some quick work done on the train or in a café for me. If I'm doing demanding work I'll anyway always be at a desk with net power, so battery life in that scenario is not relevant for me. So guess I'm good with the stock battery.

    in gaming center 1.2.2.8, I don't seem to have "low power cpu mode" in other options on the ez switch page... is that the same as "eco mode" on power options? just looking for what I need for the equivalent toggle or what version of GC I need for that. thanks

    Hey guys. I have the OP 15+ and have been trying to figure out how to wake the laptop from sleep with a usb device (either my mouse or external keyboard) but haven’t had any success. Anybody know how to do it?

    PSA....

    To anyone out there who is running Ubuntu or dual booting with Linux as I am. If you are having issues with this laptop going out to multiple displays, you most likely need to go into the BIOS and disable the secure boot option. I forgot that i turned it back on for some reason and this led to my multiple monitors not being detected even though they work in Windows. On that note, everything appears to be working in Ubuntu at this point and dual booting appears to be successful as well. Just make sure secure boot is turned off before you do your installation.

    First of all thank you all for providing so much information about these laptops!

    So I just received my GK5CP6Z (i7 9750H & 1660ti). Overall I'm quite happy with it, but it does get a little hot and the battery only lasts for 90 minutes with just browsing the web. Now I'm wondering if all the info that has been given here, like the replacement batteries and BIOS versions, can also be used for my model. I do see the GK5CP0Z as a supported model, but I'm not sure it that's almost the same as the GK5CP6Z. Hopefully it is supported and I can try a new battery and BIOS version. Thanks in advance!

    Did you happen to try using acetone or anything else? I tried using isopropyl alcohol but that didn't work unsurprisingly. I've been thinking of just finding some black electrical tape to cover the logo.
