    Hi everyone I recently bought this Clevo laptop on eBay.

    Everything was working fine, until the first month of usage.

    It's very strange because the laptop randomly stops recognizing the m.2 drive, and in the first times, that I had this problem I just changed the proprieties on the bios and its working just fine again.

    When I can't get m.2 to be recognized in the BIOS, I have the computer open, do a general cleaning inside and try to go to bios again to see if it has been recognized, and then change the value to factory or optimized f3 and f4 and the pc starts working again.

    This time was the most critical my m.2 it's not working at all.
    I cant manage to make it appear in my BIOS I thought it was like broken... So I grabbed the m.2 drive put it in my friends desktop and to my surprise, it's working! we open my windows and all files programs everything is working with no lost partitions

    And my Wi-Fi card is not working since the m.2 stopped working...
    The card name is the killer network 1525 and i really don't know what to do more....

    Both Wi-Fi and cable conections are not working. I'm using an old HDD with the windows and a Wi-Fi pen drive to use the laptop and surf the web.

    my specs are:
    i7-4790k
    32 gb ram ddr3
    980 m - 8gb
    m.2 Samsung 500gb

    my bios version is : 1.03.07 , 07/01/2015

    Any help is appreciated BTW i already tried fn + f11 update drivers download manually and nothing

    Wow, it's really hard to read what you want to say. Could you add some punctuation, form sentences and stuff? I mean, you want help, so it would really help to understand what you want to say. ;-)

    Regarding the topic: Did you try the second m.2 slot?

    Sounds like a return to seller to me. The symptoms sound like a hardware failure of the motherboard.

    hello thanks for answering my question.

    I'll try to improve the text above, but I was surprised that you mentioned a secondary m.2 input, because I never found it on the laptop, I only see 1 m.2 input and 2 sata inputs in the area where these components are located!

    Soo here is the second m.2 I really have no clue ???

    hello, unfortunately i bought it at an auction on ebay, so it's kinda impossible to return the laptop because i already have it for about 7 months..

    So my only solution is fixing

    7 months would definitely be too long for a return but, a new MOBO would resolve the issue. However, I couldn't find one on the cheap very quickly. One on aliexpress for ~$500 would preclude that option as a new laptop would be a better deal.

    You know the drive is good from using it in a different system so that rules out that piece.
    m.2 wifi would probably have the same result as the drive.

    Which leads to the m.2 ports being bad. It's possible the solder on one of the connections went bad or a capacitor somewhere else or a resistor.

    Looking for arc marks nearby might give an indication of where the problem is.

    Take some photos and post them and maybe someone will be able to diagnose the issue.
