ASUS N55 Core i7 15.6-in Notebook Review: Can One Laptop Do It All?

Heat and Portability


View Full Size

Being a beefy laptop, the N55 has a fair amount of room for cooling, which is likely what it remains quiet at idle. Though some fan noise is audible if you’re trying to hear it, you’ll otherwise not notice it. You’ll also probably miss any excessive heat, because there doesn’t seem to be much of it when the laptop isn’t exercising its hardware. 

Load up a game, however, and everything changes. Just like a gaming laptop, the N55 becomes a furious box of heat - although unlike a gaming laptop, the fan doesn’t scale up to hair-dryer levels of shriek. 

Still, I found the heat levels to be less than expected overall. This is a product that’s comfortable for lap use, as long as you don’t try to do some genome calculations while watching the Teenage Mutant Ninja Turtles. 


As I’ve mentioned numerous times, this is not a small laptop. It starts with a 15.6” display and just adds bulk from there. Even the display lid, which on many modern laptops is just a quarter or eighth-inch thick, is hefty. 

Once all the hardware and equipment is accounted for you end up with a chassis that’s 1.2” thick at the least and up to 1.6” at the laptop’s rear. Throw in a weight of nearly six pounds, and you’re looking at a laptop that’s nearly as tough to tote around as a hardcore gamer’s laptop. Short trips are possible, but product his is clearly meant for use around a home rather than around town.

That may be why it comes with a relatively small 4800mAh six-cell battery which provides the results seen in the graph above. I’m actually rather impressed that ASUS managed to squeeze this much life out of such a small battery. ASUS no doubt deserves some credit, as this system - like most of the company's laptops - comes with a custom power saving setting that seems very effective. 

NVIDIA's Optimus technology also should be given praise, as it allows the system to use energy on the operation of the GPU only when needed. Optimus also deserves praise because of its smooth operation. At this point, there's nothing that indicates it is in operation. Switching between the GPU and the IGP is smooth as butter, except when the laptop is placed in the custom ASUS power saving mode - but that mode appears to force the discrete GPU off, which is likely why there's a momentary flash to a black screen.

Even so, you won’t be able to use this laptop for more than a few hours before it gives up.

ewh shinny I'd always be polishing it! wow 5lbs i wont be able to fly with that in my pack.

No you won't, at least not comfortably (I did fly with a 15 inch laptop, once) but that's not really the point.

how much of a limp wristed girly man do you have to be to not be able to haul around a 5 pound laptop, when its in a bag?

October 22, 2011 | 01:10 AM - Posted by Matt Smith

It really depends on the bag. In my backpack, the bulk of a 5 pound laptop is slightly noticeable, but not tiring.

My messenger bag with a single strap is a different story. It's not well padded, and I can feel every pound of any laptop I stick in there. It also generally won't fit large laptops like this.

When it comes to flying, though, a laptop like this is really too large. You won't have room to use it on a plane unless you're flying first class, and its just a pain to use it on your lap when waiting to board.

lol. hells bells. are you of the ipad generation? i travelled around the planet twice over with a samsung 17inch laptop in my backpack and it was no major strain.

each time i watched a movie, played a game or listened to music i was massively glad to have a laptop of that size and performance with me. and never ever once did I sit in the middle of a movie on a cold, wet night in a foreign country thinking, "my, that laptop sure is heavy"!

for record, most hand baggage allowance is 12 kilos. this laptop weights only 2.5. are you sure you could fly with that in your bag?

i also have to say, in my experience 'messenger' bags are like 1980s school satchels; they are rectangular, clunky, inconvenient, sit awkwardly on the body and are poorly designed for carrying anything flat which could take up the space inside of them! they also seem to be sported by fashion victims, rather than practical people who wish to use powerful computing on-the-move.

each to their own, i am not knocking other - but i seriously think you have to decide which camp you are in!

Oh you big girls blouses, when I flew there were no laptops.
We had to carry The Encyclopaedia Britannica.

5lbs pftt.

Nice to see a matte screen from Asus. To me, the matte lid is unfortunate but not a deal breaker.

Anybody know how they can make this more than £100 cheaper than the N53

October 19, 2011 | 01:45 PM - Posted by Matt Smith

I can't help you there. But here in the states it is about $200 more, compared to one of the better N53 models.

Is the laptop displaying pictures that are not max res? I sure hope the bezel is not that huge. Can We see a picture of the desktop on this machine?


October 22, 2011 | 01:07 AM - Posted by Matt Smith

It is not displaying the picture at max resolution. I had it in slideshow mode, which framed the photo automatically, and I didn't even realize that you could not see the bezel in that photo until you mentioned it.

The bezel on this laptop is actually rather slim, so no worries there.

Can we get a Cinebench 11.5 run? CPU and OpenGL if you can.

This notebook seems to be in an odd area between gamers and prosumers, but it could find a home doing 3d graphics.

Could you please tell me two things

- Could you provide me a link to the website where you bought this? :)

- How much R.A.M will this hold? I heard it can take 16gb?

Thank you, please reply soon!

the keyboard on this laptop is a massive letdown. I spent nearly £700 on this laptop and I'm struggling to type because the keys are mashed so closely together with poor feedback that on average I mistype one out of every 3 keys. these type of major flaws are easy to gloss over for a reviewer but if you have to work with it on a daily basis then its a show stopper.

January 24, 2012 | 04:02 PM - Posted by Arron Renwick (not verified)

i have one of these on order its the n55sl-s2019v. when i was looking i also considered the acer aspire but every model on display had keys missing, and as i do a bit of typing (on and off) was put off by this and went with the asus simply because the keyboard had bigger easier to make out keys(well that and the spec of course)and lets face it the odd button in a different place is no biggie at least is not a cramped keyboard making way for a bloody annoying touch sensitive volume hub effort that you cant even look at without it going into spasms

March 9, 2012 | 05:33 AM - Posted by Anonymous (not verified)

I've done a fair bit of research and I think this is definitely your best option. The N55sl that is. Out of a shortlist of 5 I chose this laptop and I've been in I.T. repairs and sales for the past 10 years. You really can't go wrong.

I just purchased this machine for $950.00. At this price it just may be the best bang for your buck gaming system available!
