    Hi to all, I'm new in this forum and, first of all, sorry for my bad english.
    I've got an XMG laptop with clevo W35_37et, it's a good solution for the price (i bought used two year ago), but I have lot of issues.

    1) Fan management is ridicolous, sometimes remains to max instead cpu about 45°C, sometimes heathsink is untouchable but fan stays off, I think temperature sensor reads wrong values (specially during hight loads).
    Temps goes from 40 to 90 then to 40 again during ex: starting chromium. This 40/90/40°C has a less than 1sec period, but makes fan noisy for 5/6seconds.
    I replace thermal paste every 3/4 months, temps are identical everytime.

    2) I'm a linux user, couple of months ago, I was trying to get optimus work and get nvidia card off, something breaks ACPI stuffs in the bios, windows (or every his media installer) was broken with "system not fully acpi compliant" , cmos reset didn't anything and only solution to got it working again was flashing updated clevo-stock bios (1.02.22 / ec:1.02.13) and now in the bios mainboard model is correct w35_37et but in the bootlogo I read "ver: w15er", seems strange. Windows is working again but all issues (fan/temps) remains.

    I tried clevo control center and similar software but seems not working with this barebone.

    I read about a bios mod called prema that resolves lot of clevo bugs, I assumed story of developers and what appened. I can understand them.
    Is there a way to get it or to solve my problems without mod?
    Thanks for all

    up, @Prema are you there? Is there a way to donate for your bios mods?
    Edit: I made a video that shows the strange temp readings
    Both gpu and cpu heatsinks are touchable during test, CPU one seems about +20°C compared to gpu (I haven't a thermometer) fan runs at "medium" speed, and when I stopped test temps drops immediately at 60°C, I think that temperature is about 60°C during entire test but sensor shows wrong value during cpu load. Windows 7 and 10 have identical scenario, I used linux to show because easier

    You may have borked something not in the update portion. A full flash might be needed, speak to your reseller.

    I bought it used, so i flashed stock clevo but after this I found official XMG update, but file is the same as clevo's bios i've flashed (I compared md5). Xmg isn't a prema partner. Seems bios knows right temp but OS reads it badly (fan ad middle speed, os reports 85°C+).
    Is it possible that last owner flashed wrong bios (w150er) and bug still remains even after my update to correct bios?

    Either way a full flash would fix it.

    You would need to flash the EC, ME, and BIOS using what the original seller provides. I don't recall @Prema having made a mod for this model.

    After some researches I've found in this forum a reference to a w350et mod by prema. In my reseller website are only updates (same files in clevo's website). Seems there isn't a full flash package

    Little update: my Clevo reseller told me "if you perform a BIOS Update it is everytime a full flash and not even an update. The EPROM would be fully erased during this process", so I'm going to buy a better thermal paste in next days. I'll update this post with result

    Was that XMG? You can compare the ROM file size with the size of the ROM chip to compare.

    Yes, XMG. I don't know how to know eeprom size

    Edit: I polished heatsinks, removed cpu and cleaned socket and I applied new thermal paste (arctic mx-4), I don't now if issue was caused by bad temp-sensor contact in socket or thermal paste, but now temperatures are exellent (35/40 degrees idle, 70 degrees under 100% load, 80 degrees with cpu/gpu simoultaneus 100% stress), fan never reach max speed

    Sounds like the heatsink was not sitting quite right.

    Now I'm still interested to biosmod not for issues but for overclock chance, 65degrees on full load it's very cool

    A CPU replacement could be useful? Now I have an i7-2620M, is it a bottleneck for a 660M? I'd like to play newer games with low settings too. I've seen my barebone with a i7-3630QM in online benchmarks

    It's not a bottleneck, but you might see a subtle improvement in some applications by upgrading.

    I know improvements will could be ex. in compiling and math calculation. But can I have improvements in newer games with low graphics settings?

    Possibly, but again, it would be a small improvement. Some titles you may see exactly the same performance.
