    Hey everyone so I still have a problem with my Clevo P870DM-G Laptop it uses the Dsanke Bios for my i5-8600k for GPU I have a GTX 1060 MXM.
    One day my laptop just turned off spontaneously trying to turn it on just resulted in a backlight bootloop.
    The backlights would turn on but the laptop would just turn on and off in a boot loop so I left it alone for a while now the laptop turns on backlight and everything but nothing comes on screen.

    The power button backlight comes on, the backlight behind the screen comes on, but not the keyboard backlights.

    The GPU of my laptop looks good it hasn't shown any signs of physical damage I tried removing the CMOS battery I tried FN+D + Power nothing has worked so far.

    Tried removing the battery and powering it on with just the cable

    Retry reflashing the BIOS with a spi programmer

    Have you got access to another MXM GPU ?

    I just think it would be safe to try another GPU 1st

    Does removing the gpu and trying to power the system change the behaviour?

    Did you retry flashing the BIOS with a spi programmer?

    Have you tested with an external monitor?

    I'm trying to do that but I have a bit of a dilemma the cable for the test clip the red cable and the grey cable next to it somehow got snapped off, so I'm trying some wire repair.

    Though I personally doubt it's a bios error unless the boot loop initially where the backlight would turn on and loop would be a symptom of that.
    Though honestly if I can avoid a bios reflash that would be preferred since getting the bios chip exposed alone is a pain in the ass, doing the whole test clip spi programmer is another pain in the ass as well.


    Not yet I'll do it after I resemble the laptop

    Its more likely hardware rather than firmware related with those symptoms.

    It was working fine until June 13 2019.


    I took out the CMOS battery and put it back in after a bit, the backlight issue got resolved but nothing comes on screen.
    Currently the fans works, the keyboard works I can press FN + 1 and get max fan speed.
    It powers on with the battery and power cable so it still charges
    But there is still no display.

    Specs are GTX 1060 MXM, i5-8600k(bios modded), 8GB DDR4 Memory, 500GB SSD, and 1TB HDD.

    I also tried what you suggested hooking it up via HDMI it didn't work
