If you’re a person who’s tired of slow Celeron laptops, here’s a viable candidate for you: ASUS X555LB-NS51. It’s a 5th Generation Core i5 powered notebook with ample 8GB system memory and 750GB hard drive. Also the screen doesn’t look bad, after all it’s a Full HD display. But are there other things to keep in mind, and does the laptop essentially offer decent – or even great – value? Keep reading and you’ll find our professional opinion about these matters below!

General performance

The ASUS X555LB-NS51 laptop has a decent performance for more demanding programs. It runs on the Intel Core i5-5200U, a power efficient dual core processor, offering 2.2GHz clock speed with 2.7GHz turbo. Indeed, most software – lightweight or heavy – you throw at it will be handled without bigger hiccups, and if you’re interested about benchmarks, the CPU Mark points this processor gets is 3500. Compared to, say, 5th generation i3s with ~3000 points in the same test you can see the difference on paper, although I must say in real life that difference isn’t too noticeable.

The laptop comes with a satisfying 8GB memory, the usual DDR3L 1600MHz type. It’s a good amount to begin with, and will probably be fine for the whole lifespan of this system. Just keep in mind you can’t upgrade it – the motherboard features only one DIMM socket.

ASUS X555LB-NS51 has a 750GB (7200RPM) hard drive as the storage solution. In case you want to put thousands of photos and perhaps pieces of music on your computer, such a spacious HDD is a great choice. However, if you don’t have so many big files, but instead are looking for better performance you might want to replace the drive with an SSD. Users reported it’s tough to do (requires a lot of tinkering) but definitely possible with some skills. There’s no space for two drives, so you indeed have to do with one physical unit.

Can I use it to play games?

ASUS X555LB-NS51 is not the worst notebook for gaming. See, it includes GeForce GT940 (2GB DDR3 memory) which is a dedicated card, although not a very powerful one. As a real life example, The Witcher 3 is playable, but will require low settings and 1366×768 resolution for ~25 frames per second. Using medium settings and similar resolution, you should get around 50FPS playing GTA 5.

Is the screen good or bad?

ASUS X555LB-NS51 features a 15.6″ non-touch matte display appropriate for power users and digital artists, that’s because it supports Full HD. Overall, you’ll get much more screen estate than on a cheaper 1366×768 display. The panel type seems to be TN.

Does it work with peripherals/devices?

ASUS X555LB-NS51 has three USB ports, the usual amount in these 15.6″ models. Two of those ports are USB 3.0. There is also a possibility to connect a monitor (like TV) to this laptop, there are VGA and HDMI outputs available.

You’re good to read and write from/to CDs and DVDs using this unit, a DVD burner is installed inside. Transferring files from memory cards won’t be problematic either, the notebook has a built-in SD card slot.

Connecting to Internet happens through single band 802.11 n-type WiFi card or Gigabit Ethernet (RJ-45) port. Bluetooth 4.0 is supported too.

There’s a 1280×720 webcam available, you can have video chats using it, but recording and publishing videos might work better using a camera with higher resolution if you want the best quality.

Miscellaneous things

There’s no backlit keyboard available, however a standard numpad is there.

Operating system is Windows 8.1 Home (64-bit), you might want to upgrade it to Windows 10 for free.

Battery (2 cells 37Whrs) life on this unit will be four hours on a good day, if you’re surfing the web. To replace the battery you need to take the laptop apart.

The case is made out of plastic.


ASUS X555LB-NS51 is a laptop for the power user minded. There are a couple of things to keep in mind, those being the Full HD display for some real screen estate and dedicated GeForce card to allow many games run at medium-high settings (newer ones perhaps requiring low settings). Processing power is rather strong thanks to the i5 processor, and 8GB RAM will help with things running lag-free. I would get this kind of notebook for general use, including occasional demanding stuff such as photo editing and programming. If those things ring a bell to you, you have a good reason to take a closer look at this ASUS.
