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!
