Asus ZenBook UX303U Battery Replacement

Difficulty

Moderate

Steps

9

Time Required

7 - 10 minutes

Introduction

This guide will show you how to replace an old worn out or dead battery in an Asus ZenBook UX303U laptop.

  1. RnAAXb2Q6HjJ6g55

    • Remove the two round rubber feet at the hinge-edge of the laptop.

    The process took me about 30 minutes. If I were to have to do it again then I could probably do it in 10 minutes now that I know what is involved!

    • Remove the eleven 4 mm Phillips #00 screws from the back panel.

    These screws on other models are Torx T5 or T6, not Phillips

    Dylan Warburg -

    T4 screws on all but the two under the rear rubber feet; those are Phillips PH0 (and my model had two square rubber feet).

    Gregg Stanley -

    Agree. Same as my laptop.

    • Using a plastic opening tool pry the back panel off of the laptop.

    I lift more than the last photo shows. Dark rubber with plots, visible on photo are blocking the opening.

    Mine was also stuck at the back with a bit of tape (for grounding?) I did my best to make sure it was replaced during re-assembly.

    • Pull the speaker cable out of its four retaining clips with either your fingers, or a plastic opening tool.

    Skip this step on UX430U

    I skipped this step and was able to gently pull it out when I removed the battery in step 8.

    • Remove all seven 2 mm Phillips #00 screws from the battery.

    Mine was missing the lower left and lower right screws.

    • Pull the speaker connector toward the edge of the laptop to disconnect it from its socket.

    Skip this step on UX430U also

    • Lift the battery connector straight up off its socket to disconnect it from the motherboard.

    • Do not pry on the socket itself or you risk damaging the motherboard.

    The replacement battery I received from ifixit had longer wires than the original battery which made re-installing it a bit awkward, but I was able to bend them to the side a bit.

    • Lift the battery and speakers up and pull out to remove.

    • Check underneath the battery for the wire assembly connecting the touchpad to the motherboard. This connection may stick to the underside of the battery. Be careful not to damage it when removing the battery.

  9. XfFVoncLAPIryx1r

    • Remove the speakers from the old battery.

    This was a bit more fiddly than expected given the speaker arms are stuck to the battery

    Jon Kerridge -

    Yes, it was taped on their quite strongly. I just tried to make sure the tape stayed stuck to the speakers and not the battery.

hello! Where I can buy a UX303U battery for my Asus netbook?

thanks

jeannette dreifus -

There are two screws holding the back panel in place. They are located below the two rubber pads at the back of the pc. They must be removed in order to open the back panel.

Dave Man -

Just gone through this, but two problems surfaced. 1 it won’t connect to our usual WiFi router and can’t figure out why. Is it possible to damage the WiFi connectivity when removing battery? 2 there’s no indication of charge levels. It says 100% and doesn’t change. Thoughts?

Barny Harper -

Take all that back. Went back in and battery connector hadn’t clicked in far enough. Seems to be working fine now.

Barny Harper -

The bottom of the pictured device may feature Phillips #00 screws, but I also have this laptop and the screws around the edge of the bottom panel are Torx T5s on my device.

Nick Brennan -

Same here, they are really small Torx on my Asus UX303U!

Dave Taylor -

Can I use this laptop without a battery?

m khn -

Installation was simple, but took me longer than as described. That was due to battery I purchased from iFixit had a longer power cable than original. This required me to angle the power cable in first and secure the battery before finally being able to secure the cable to the socket. Other than that, it worked out.

Jorge Camacho -

Good steps and pictures, thx. Tool kit nice, w. the top tray for keeping sorting screws.
