Heat and Connectivity

View Full Size

Opening SpeedFan revealed very typical internal temperatures. The ASUS K53E idled around 42 degrees Celsius and would launch as high as 58 degrees Celsius under load. Those temperatures are not a problem, but the increase of the K53E’s external temperature is more uncomfortable. After running our benchmarks I found that the left side of the keyboard was quite warm, as was the same side of the laptop’s bottom. 

At idle, the system fan is pleasant and easily blends into the ambient noise of my apartment. At load, however, the fan spins up to gaming-laptop levels of whoosh. The K53E certainly seems capable of moving some air, and it’s a shame that doesn’t result in more comfortable keyboard temperatures under load.

Most of the K53E’s connectivity can be found on the left side in front of the fan exhaust, where one USB, one HDMI, on VGA and one Ethernet port reside. Oddly, the power adapter also plugs into the laptop on the left side, and rather far forward as well. Although this placement felt a bit awkward, it isn’t terrible in practice. The right side reveals two additional USB ports, and a card reader can be found on the front left near the touchpad.

Battery Life and Portability

The ASUS K53E ships with a 56Wh six-cell battery, which is about average for a laptop of this size and a bit larger than the battery shipped with the Sandy Bridge quad-core powered ASUS N53 we recently reviewed.

When thrown into the Battery Eater test the ASUS K53E died in just one hour and twenty-seven minutes.  Yet when placed into the Reader's Test, the K53 lasted over five hours and thirty minutes, which is nearly as long as the dual-core Atom powered Eee PC 1215. The K53 also managed just over four and a half hours in the continous use WiFi test, although that's just half an hour longer than the N53.

I'm slightly confused by the results here, as the Battery Eater standard test really ripped through the battery. It's only natural that an increase in GPU performance would come with a battery life penalty, but the results are so dramatic that I doubt that's the whole story here. Fortuantely, the battery life performance in less intense use is far better. There's more than enough battery endurance available for a trip to your local cafe or a long layover. 

You may have trouble taking advantage of the K53E's battery life, however, because it isn't a portable package. The 15.6" frame isn't massive, but it does require a fairly large bag. The laptop’s 5.73 pound weight is hefty, as well. While a trip down to your local coffee shop wouldn’t be an issue, traveling long distances with the K53E could be a pain.

Does is come in any other colors besides mocha? Black preferably because I'm going to be gaming on this laptop and the brown shade might be distracting.

This is a great laptop, I bought it like 4 months ago and its great, its quick, really basic, a good standard for if you want a clean slate that's how I thought of it as of buying a new laptop it was a cheap price and I like the stats too it, I planned on using it for schooling but as of right now I produce music on it and playing a few games on it and still runs very smooth and could handle a lot, I'd suggest this laptop if your looking for something to that kind of use, for its price

I am noteing this problem tho, with windows 7 I heard there's a couple crashes kinda things going on and sadly this happened to mine, mine will not start up even after trying a called service troubleshoot fix from the manufactuarer and other fixes that I have tried have not worked, I currently have to send the laptop into the manufacturer for them to fix which is pretty silly that their common fix did not work so just noteing that something internal went wrong with it, maybe just mine that went wrong but not sure of others but just letting you know what happened to mine.

Id buy this with an i3 sandy bridge CPU in a heartbeat.
Why select the i3 over i5? Just battery life?
also is this 3 USB3 ports? wow. -
I believe it's 1x USB3.0 and 2x USB2.0.
