Asus Zenbook UX303LB (940M) Subnotebook Short Review


Follow-up. The 13-inch laptop is an old acquaintance. We tested the GeForce 840M model only a few months ago. Now we are taking a quick look at the new 940M version. Has the racer turned into a rocket?

The buyer gets a stylish, compact subnotebook with a long battery life, swift SSD, and a viewing angle and rich color IPS screen in the Zenbook UX303LB-R4079H (Broadwell i5, 940M) for presently 1100 Euros (~$1204). On top of that, a GeForce 940M that...

Light weight laptop. Looks nice

This laptop is notorious for their hindge problems. just google model name and Hindge and you can see how many other owners are having a same problem. I'm careful with my laptop and Mine broke after 14 months of use. DO not buy.

Solid build, good battery life, and enough memory and CPU power to do most tasks (including Java development)

Slightly thicker than my previous Zenbook UX31

Very good for the price


This is a great laptop for the price, however I would be gentle with the hinges if you decide to buy one.

Price Specs Upgradable SSD Upgradable Ram (a single slot)

Screen brightness could be better Hinge broke after 10 months. Not sure why or how, I closed the thing and heard some crunching and crackling. That was it, one hinge is now broken. It still works though, just threw some duct tape on it to hold it...

Exactly what I wanted


Why there is no other reviews on this, I'm not sure....but this laptop/ultrabook has exceeded all expectations. If you're considering buying this product, you're probably looking for: 1. Something slim/light weight 2. Able to handle most day-to-day...

Screen bezel is a little thick for my liking, and the silver aluminum case attracts finger prints easily. Also some may not like the gorilla glass screen which causes glare, but that is being super nit picky.. Certainly not enough to dock an egg.

ASUS ZenBook UX303LB


I love how light this laptop is! I got a new one to replace my old Asus which finally gave out, I struggled with the old one as it was so heavy when you had been carrying it for a while- so far this one is amazing

The track pad can be very sensitive- had the laptop come with more detailed instructions I could understand it better. However this is not really a bad thing- just awkward untill I understand how to use it!

Looks good. Very Small and light, Good battery- life 6 hours+ Can play latest games on it, not maxed out though. Very quick boot up.

HD size is very small for today day's use. When closed it's a little fiddly to open.
