    My CM5 laptop power input suddenly stopped working. The power adapter is working, I tried another adapter, didn't help. The laptop still booted and worked normally until the battery became exhausted.
    What could have happened? Is there some sort of fuse on the board?
    Is there component layout and/or schematic for the laptop carrier board public available? Thanks.

      I noticed a tiny component near the power input connector was loose. Looks like a LED? Could it have dis-soldered due to some sort of overheat?

        I don't have a direct understanding of what happened to this computer, why does it seem to have so many impurities inside.
        If you need any information, please send an email to george@cool-pi.com
