Hello everyone,

so i was wondering if anyone knows if and where i could get a I/O USB board for my helios 300 (PH315-53-72XD).

long story short i noticed after connecting various devices the connection is very poor (such things like lights extremely dim on the connected device or not connecting at all and the effect is changed by simply wiggling the connection to get a proper connection.) only 1 of the ports has this issue and the other one next to it works just fine however, this laptop is less than 2 months old and im about to add more storage and i wanted to replace that board while i was in there.

any advice is greatly appreciated!

    Im not sure you can, I think all the IO is integrated into the mainboard looking at a teardown of it  ( https://www.notebookcheck.net/fileadmin/_processed_/9/d/csm_Helios_300_19_66d9b252dc.jpg  )  the only way would be replacing the mainboard. If its not working properly i would make sure to raise a ticket with acer support to see if they suggest a RMA

    when i came up empty handed with finding the board i thought the same thing however the ports on the right side of your picture are their own separate board once the M.2 drive thermal shield is removed. you can actually see the edge of the ribbon cable under it on the right. i am trying to avoid sending this laptop off for something well within my understanding of replacing if i had the parts.

    Thanks again.

    before i go into the process of contacting acer, do you know if they send replacement parts or do they want to do the work themselves?

    also if anyone reading this happens to be able to get a part number i would be greatly appreciative!!

    I think if you send it they would insist on installing it.

    After a bit of digging the part number *May* be  55.Q5MN4.001   

    55.X.001 and 55.x.002 seem to be the IO boards, and that one looks the closest i can see  (  
    https://www.zandparts.com/en/acer-55-q5mn4-001 ) but lots of places have this tagged as for the 52 not 53

    Any chance any of the ACE's could confirm :D?

    The issue has now spread to the other port on that same board. i am at a loss as to whats causing this unless one of my devices is damaging the ports.
