    I had my first clevo laptop from mythlogic, it was a used laptop bought through the forum here, it was only 6 months old when i bought it, within three weeks it crapped on me, power led started blinking, fan spun up and display went black, i chronicled my rma experience with myth here. The problem was happening randomly enough that it took myth more than a month to fix.

    Two weeks ago I bought a clevo laptop from gentech Np8454 with 2070 oled, and last week it gave me the same thing, power led blinking, fan spinup and then it shutdown. It happened intermittently, once on monday and the other two times on saturday.

    So maybe it's because clevo is cheaper than other brands that the quality is lower? :) or maybe it's just me LOL

    but a few things i notice about the NP8454 oled
    1. The oled screen on the clevo i believe is of lower quality than the one in aero, or maybe i just got a bad one :) The left side is brighter, i noticed this when opening a private tab in firefox (in a well lit room), the solid purple was not uniform and when i set a solid black color on the screen and turned off the light i could see the "backlight bleed" (well it's a oled glow) on the left and right edges only the middle portion is really black
    2. And speaking of oled screen, the behaviour is quite odd, going from 90% brightness to 100 not only the brightness changes but also the colors especially the darker ones. Gray for example will be darker at 100% brightness compared to 90% initially i thought it has to do with PWM but now i'm not sure
    3. The fan was aggressively quiet even in performance mode, so the laptop ran really hot :) i had to put a 25% offset and the temperature went down around 10 degrees or so
    4. The keyboard gets really hot especially the part over the gpu even when the gpu is only 60 70 degree
    5. It seems like the nvdia gpu is always on everytime i opened the fan control it always shows the temperature of the gpu even though it has optimus, in my old laptop with optimus it won't show the gpu temp if it's not on.
    6. The gpu fan won't spin up right after boot and it scared me, i thought there's something wrong with the fan :) but i think the temperature is low enough that it didn't need to spin (and also because the heatsink of the cpu and gpu is connected so i believe when the temperature is low enough the cpu fan is enough to dispose the heat of both)
    7. The battery wear level went up from 1 to 5 percent within a week and i only used the laptop on battery twice, and in both times the battery only went as low as 80%
    8. I couldn't start my app that uses nvidia gpu on battery the app will launch and then close itself
    9. and lastly the problem i mentioned above, the first time the power led was blinking green and it was right after windows update, i ran unstream app the window didn't show so i opened task manager and it froze then i got a blue screen and then it shutdown by itself, the other two times it was blinking yellow or ornge, the first time was when i opened virtual box but it didn't start so i opened task manager and it froze then the blinking and fan spinup so i pressed the power button to shut it down, the last time it was right after power up i started vlc to watch a video suddenly i heard the fan spin then i noticed the power led blinking then it shutdown by itself
    10. (minor?) freezes, a day after i received the laptop, i safely ejected my usb and so windows gave the notification of usb is safe to be unplugged, i wanted to clear that notification so i pressed the new notification button on the bottom right of the screen and it froze, the second time i just opened task manager after starting virtual box and it froze
    so hopefully my experience can better inform other poeple considering to buy clevo or if people have similar experiences they can tell me how to fix it or what I'm doing wrong :)

    UPDATE: 10/2/19 it happened again last night after turning off fast start up but this time i had my phone with me so i took a video of it. This time during shutdown it froze power led blinking orange fan spinup and then bluescreen with driver power state failure and shutdown by itself. I opened the minidump and it says acpi and pci sys which is very generic (both dumps have the same thing).
    And as I was about to ship the laptop back it happened again, first the mouse froze i couldn't move it or press the mouse buttons then i press alt f4 to shutdown and it froze (but keyboard was still functioning) during shutdown (this time it was on battery) and then the blinking fan bluescreen and shutdown so i think the first freeze i saw when pressing the new notification is the same thing it's just that i shut it down immediately.
    So it's been 5 times now, 3 with blue screens two without. Since the symptom is exactly like my old clevo i believe this is a hardware issue, the time between failures get shorter and shorter so I decided to return it to gentech and maybe change to aero.
    The only unpleasant thing is that i have to pay shipping even though it's a defect and i think i'm done with clevo :)

    Did you ever try to update their BIOS and EC and see if the problem was solved?
    There is no perfect brand anywhere.. Not defending Clevo but I've had my share of problems with Asus and MSI and they are better known brand with crappy post services.. In my opinion..

    You can force programs to open on the IGPU in the nvidia control panel (make sure the fan app is) and monitor what is lighting up the GPU using the usage indicator.

    Battery wear is also a guestimate that settles after a while, if it changes rapidly from now it's worth keeping an eye on.

    ok :) learning so much just from being on the forum
    what's sager policy if they can't reproduce the issue? i'm afraid sager would just ship back the laptop saying cannot reproduce issue
    it's so intermiten i'm confused what the actual problem is, yesterday i used the laptop almost 10 hours straight with no problem but the day before it gave me the blinking led and shutdown twice
    i'm debating whether i should return the laptop

    1) I agree with checking for updated BIOS and EC.

    2) Consider trying Obsidian-PC's Fan Control application. You can use their profiles' logic instead of EC's to keep temps regulated. (Not free but you can install for free to test to see if it works)

    3) If you haven't backed up yet, do so, and try a fresh install of Windows. Sometimes the image they use to set things up with is less than stable. Gather up the drivers you will need first. Obsidian-PC's Driver app makes that super simple if the model is supported. (Not free tho)

    4) I had to repaste my Clevo after 3 months. Perhaps you system has a marginal paste job and needs to be redone.
