Asus U31JG review

 

Asus' U-series laptops have impressed us over the last couple of years with their long battery life, despite the use of normal Intel Core processors, rather than the low-voltage variety used by most other ultra-portables. The new U31JG follows this...

Great performance and battery life in one laptop is miracle enough, but the two year warranty and great screen seal the deal.

Asus U31JG review

 

It's not just a fashion statement either: the Asus U31JG aluminum trim reinforces the plastic chassis, creating a sturdy ultraportable laptop that packs enough power to play games and run your presentations while remaining light enough for you to carry...

Asus has a reputation for building reliable laptops, and the durable Asus U31JG is no exception. It outperforms and outlasts many comparably priced ultraportable laptops, including Asus's own U33Jc. The U31JG isn't optimal for multimedia use, but if...

Asus U31JG

 

The Asus U31JG, designed for urban professionals on the move, boasts a stylish brushed-aluminum finish that coats the lid and wraps around the black plastic keyboard. It's not just a fashion statement either: The aluminum trim reinforces the plastic...

Discrete graphics card ; Lightweight, with great battery life

Display has poor viewing angles and too much glare ; Mediocre keyboard and touchpad

The U31JG is ideal for getting work done on the road, but movie and music buffs should look elsewhere.

Asus U31JG-A1

 

The Asus U31JG-A1 is a slim little laptop that lasts all day on one charge. Features like Bluetooth and battery-life are great, but a flawed trackpad mars the overall package.

Aluminum construction is light and sturdy. Slim portable design. Backlit keyboard. 8 hour battery life. Bluetooth connectivity. Discrete graphics.

Trackpad is almost unusable. No optical drive.

ASUS U31JG-A1 Review

 

The ASUS U31JG packs an Intel Core i3 processor, Nvidia graphics with Optimus technology and almost eight hours of battery life into a thin and light 13.3-inch chassis weighing less than four pounds. What's not to like? Read our review.

Thin and light ; 7+ hours of battery life ; Good performance

Too much keyboard flex ; Poor speakers ; MSRP too high ; The ASUS U31JG thin and light combines good performance and battery life at a price that's just a bit too high.

Asus U31JG-A1 Review and Ratings

 

This machine is a serviceable thin-and-light laptop, but with Sandy Bridge-based models flooding the scene, it's hard recommending this model, which is based on an older processor.

Lengthy battery life ; Sturdy, stylish chassis ; Two-year warranty

Some design quibbles ; Outdated processor ; No backlit keyboard ; No USB 3.0 ports

Asus keeps the bloatware to a minimum in this machine, and it includes a number of its own utilities. Asus LifeFrame works with the VGA (0.3-megapixel) Webcam and features a basic assortment of hokey image effects. More useful is Asus Secure Delete, a...

Consumer review (newegg.com)

Poor Service

 

We have another ASUS notebook and tablet, as they were a brand that I previously thought was high quality. Having a mechanical issue within the first few weeks is bad enough, but their repair service is absolutely the worst. I will not purchase this...

none

Service terrible - fan needed to be replaced after 5 weeks of use. ASUS sent us a postage paid label, which sounded great until we found it took a week to get to them ; In spite of having an RMA # we can never access updates on their on-line system....
