Introduction

This is a guide designed to instruct you on how to replace the power port on your Chromebook. Make sure that your computer is powered off before you begin to work on it. All you need for this replacement is a Phillips #0 screwdriver, a plastic spudger, and tweezers. Remember to be careful when handling the internal components of your computer as they are fragile.

    • Working on your device while it is turned on may result in electric shock. Make sure to shut down and unplug your device before you begin.

    • Turn device over so the bottom panel is facing you.

    • Remove the eight 4mm Phillips #0 screws.

    • Remove the two 6mm Phillips #0 screws.

    There are two tabs on the battery opposite the connector side that need to be inserted into the retention slots or the battery won’t sit flat. Need to do this before reinserting the battery screws.

    Also, I found that #00 Phillips works best on the 4mm screws.

    • Open hinges to the screen. and then slide base of the computer off of the hinges.

    • It is easiest to do this by holding the hinges in place and opening the entire laptop. Then close the laptop while letting the hinges remain open.

    • This will detach the base of the computer from the screen in order to allow better access to the power port.

The guide is excellent and easy to follow.

However, a word of advice. If you do want to disconnect the wires be warned that their terminals are extremely small and difficult to get back if damaged. It appears to be a soft metal and if you do not line them up exactly the holes on the wireless chip will distort and you will find it impossible to put them back on. I speak from experience and the only solution is to either buy a new wireless adaptor or to solder the wires on.

That itself is fiddly and I have yet to find out if it has worked on mine. (I need to buy a soldering iron). As the wire is an antenna only, I am assured that it should still work even without a connection, provided that you are near the router.

My recommended procedure is not to disconnect the wires but instead to take the small screw out of the adaptor itself and then press down and slide it out. That will free the two halves of the computer without separating the wires.

Thanks for giving my Chromebook a new lease on life! I followed all of the steps except (1) disconnecting the wireless adapter and (2) separating the base from the screen. Those two steps seemed unnecessary, and since I don't repair my own devices regularly, I was worried I might cause more trouble for myself than the convenience was worth. The rest was very helpful and clearly written/highlighted in the photos. Thank you again!

Thank you so much for posting this! I had to replace both the charge cord and the power port when my computer fell to the ground with the charger plugged in. I used the part number that was posted (50.GC2N5.003 - thanks Scott!) to find the charge port and then followed these steps exactly as K.E.H. Ellis did (all of the steps except Steps 5 and 6) and everything worked perfectly. Thank you!
