HP Pavilion x360 14m-ba114dx 14m-ba-XXX disassembly guide.

In this guide I show how to disassemble an HP Pavilion x360 14m-ba114dx Convertible PC (2017 model).

You can use this guide for many other models in the HP Pavilion 14m-baXXX x360 computer line: 14m-ba011dx, 14m-ba013dx, 14m-ba014dx, 14m-ba015dx and probably some others.

What I don’t like about this model?
– Both memory slots and the M.2 SSD slot are hidden under the motherboard.
– The display panel can be removed only after the motherboard removal.
– The DC jack bracket also blocked by the motherboard.
– The keyboard is not removable (pretty standard for newer laptops).

Repair tools needed for this disassembly: Phillips screwdriver #1 or #0, tweezers, case opening tool.

Top case and battery removal

STEP 1.
Remove all screws located on the bottom of the laptop. Two screws (red) are hidden under the self-adhesive rear rubber feet. One screw (yellow) is hidden under the self-adhesive seal. All screws are different. Keep track of them.

    Is it possible to install a 2.5″ drive into the laptop? I see that there is a space for it and I believe that it is just missing a ribbon cable, do you happen to know the part number?

      Justin, this laptop supports 2.5″ hard drives and it’s possible to install it. Just make sure to install a 2.5″ solid state drive, not a regular slow spinning 2.5″ drive.

      For mounting the 2.5″ drive you will need a rubber sleeve. It will secure the hard drive in place. The rubber sleeve part number is: 924283-001. Though I think the rubber sleeve is optional if you can figure out another way to secure the drive, maybe adhesive tape will work well too

      HP manual doesn’t mention the part number for the cable which connects the drive to the motherboard. It’s possible the cable comes with the rubber sleeve. Maybe not.

      I did some research and it looks like the hard drive cable part number is: 450.0BZ05.0001

    Hi, I have a Pavillion x360 m convertible mod: 14m-ba114 dx. A bad batery burned or shorted these two components: PU4406 and PU4407. They are just below the white connector located at the top right corner of the motherboard. I neglected to replace the battery going bad when I could, and now the battery died taking with it at least these two components.
    What information do you have about PU4406 and PU4407? How can I get a diagram of the MB? Where can I get a new or refurb MB?

    Thanks for shareing of your time and knowledge.

    They are N-channel & P-channel mosfets. Just read the numbers on the chips self….They are totaly different from the PU number. the PU is only the boardnumber of the part.
    It looks like the 4407 = AON7403 p-channel.
    Probably 4406 = n-channel = AON7408= 6V7259
    look at ordering always to the desciption 3 x 3 which means 3×3 mm square.
    If the get extremely warm it is not garanteed that they are faulty. There can also be a short circuit behind them…..
