    The way I would approach this problem is by making boot logs
    persistent [1] so they could be searched for clues (kernel module
    name, device hint, etc) after each boot.
    There was an intention from a systemd developers to make persistent
    logs the default, but I'm unsure if that change made it into Debian
    already.
    
    I also recommend you to check what BIOS version this laptop is using
    currently and update it to most recent one from official Asus
    support website. [2]
    Double check if this laptop model (UX501JW) is the same you have.
    BIOS update might resolve the issue on the spot.
