Introduction

If your Asus ZenBook UX330U or UX330UA never holds a charge or has a short battery life, then you may need to replace the battery. Before using this guide, look at the troubleshooting page located here for possible fixes that do not require any disassembly. This guide can be used to remove the back panel and battery for the ASUS ZenBook UX330U or UX330UA.

The battery is an essential part of the Asus Zenbook- it gives your laptop life. Before removing the battery, inspect it to make sure that it is not swollen, and that all power has been discharged from the battery. For more information about battery safety, please look at this guide that iFixit has provided.

Before beginning any device disassembly, please power off and unplug your device.

  1. Before starting any device dissasembly, please put on the anti-static bracelet provided by iFixit. Make sure the metal part of the bracelet is touching your skin. Remove the alligator clip at the end of the bracelet by simply pulling it off, to reveal the bullet connector. Insert the bullet connector into the ground port of an outlet.

    Why do you need to remove the battery? You can see the SSD just above the left of the battery.

    You can skip pass step 5 and go to 10, or I am missing something?

    I think you mis-identified the tool here—this looks like tweezers.

It would be nice if you mentioned the model of battery the Asus UX330 uses, even of you don’t carry it.

Other than that, great instructions. I’ve ordered tools from you folks and would have ordered the battery if you stocked it.

My wife can hardly wait for me to fix her computer!

Thanks!

Glad the guide was helpful! We (students) did this project as part of a course for our university and compiled all the information ourselves. I don’t remember if we ever found a part number for the battery, which would explain why one wasn’t provided in the guide.

Your instructions made the battery replacement as smooth as silk! I really hate getting into laptops, but you made it (almost) painless.

The problems were, as usual, my big hands and my aging eyes.

Thanks,

Mike

I was pleasantly surprised at how easy the battery replacement turned out to be, partly due to the design of the ASUS UX330, but also due to the excellent repair guide. Thanks!

I must be a klutz. I attempted this procedure, but when finished the laptop booted but has very dim display and the network adapter didn’t stay powered up. So, I took things apart again and tried to put it back together more solidly, and then the network came back, but the display is still quite dim. I suspect I made a poor connection at the motherboard bridge, but I don’t know how to fix it. (I would not expect a new, but bad, battery would dim the laptop when on power, right?

Hey there, I’m one of the students that compiled this guide. First of all, I’d suggest checking your brightness settings in Windows, as it may have reset when all power was removed from the laptop. If your brightness setting is maxed out on the computer, it is possible that the backlight ribbon cable got unplugged, in which case you’d have to take it apart again and look for that specific connector.

Scott Hansard -

Thank you for a concise and accurate guide. The pictures were clear and the circles and arrows helped locate all the screws, even that one next to the battery connector. Total time was about half an hour because I also did some cleaning to get rid of about three years worth of gunk.

The battery model number on my original is C31N1602. Rated at 11.55 V 57Wh, min 4800 Ah. Hope that helps anyone. I bought a replacement for about $50.

Hi Mark,

Thank you for the detail of the model.

Where did you buy the replacement battery?

Kind regards

I used this guide to replace the battery but now have a very strange problem. I replaced the battery without a problem, reconnected everything in the reverse order and screwed the case back together. When I plugged in the power cable, the the power light on the side, the on on/off button on the keyboard , F2 and Caps Lock all lit up. The laptop did nothing. I took everything apart again and carefully repeated all steps again with the same result. I even put back in the old battery and still the same result. In much trial and error I found out that everything works fine with the new battery (the machine starts properly and the battery starts charging as long as I do not reassemble the case. As soon as I put just one screw in the the rear cover and tighten it I get the problem.

Unfortunately, I bricked my computer trying this repair, and do not recommend others try it. Issues I encountered:

1) The rubber feet at the bottom are *incredibly* well glued on. I cut myself on the recommended Jimmy. Another guide recommended using a flatheaded screwdriver instead, and I found that easier to brace against my finger.

2) The battery itself didn’t quite fit correctly. While the same part number, it was not the exact same, with a slightly different battery connector cable (which couldn’t be latched down in the computer).

3) My kit shipped with *angled* tweezers instead of *blunt* ones. I believe attempting to use the angled ones where the blunt ones were called for, combined with the issues I had with fit, may have damaged some components

I found both the motherboard ribbon and the battery connector very difficult to try to secure with the new battery in, and after giving up on that and going back to the old battery, my computer won’t boot at all. I hope others have more success than I did.
