The 11.6” CTL NL6 Education Chromebook recently arrived at Promevo! CTL has put together a device that promises to be powerful and durable enough to stand up to students’ demands. Here at Promevo we were eager to take a look at this new Chromebook and run it through our battery of tests to see how it would perform.

Case. The CTL NL6 Education Chromebook’s case has a simple but refined design, with a white matte finish and non-slip texture that hides wear and tear as well as allowing the user to better grip the device. The CTL NL6 Education Chromebook also has a retractable handle on the spine, which makes this device easier to carry from class to class. The construction is thicker near the rear cover and frame around the screen, sides, and corners to absorb the force of bumps and reduce damage when dropped. This device is also reinforced around the ports and hinges for added durability. The fanless design not only reduces the noise, but also eliminates the need for bottom vents, which helps keep debris away from the electronics.

Keyboard. The CTL NL6 Education Chromebook’s keyboard feels spacious for an 11.6’ device. It has low profile black keys with white letters, that are nearly silent while typing and have a fast response time. The keyboard is also said to be water resistant, and channels liquids away from the electronics to prevent damage. Like all Chromebooks, there is no number pad. The keyboard is 10.75” across with the letter and number keys measuring 0.625” × 0.625”.  The keys are not backlit. Overall, the keyboard is very comfortable to use.

Touchpad. The touchpad on the CTL NL6 Education Chromebook is one of the larger touchpads out there, measuring 4.125” × 2.4375”. It has multi-touch capability with no visible buttons. The touchpad also has a tactile feel with a click that you can both hear and feel when pressing down on it.

Display. The CTL NL6 Education Chromebook has an 1366 × 768 HD LED anti-glare display, with a 16:9 aspect ratio. The bezel around the screen is slightly bigger than average, with the top and bottom measuring 1.125”, and the sides measuring 0.8125”. 

Speakers. The speakers on the CTL NL6 Education Chromebook are located on the side of the device towards the front. We turned up the speakers to the maximum volume to see what they could do, and we found that the CTL NL6 Education Chromebook had good volume and sound quality. Even at a high volume, there was little to no distortion present.

Temperature. At the beginning of the test, we took a unit heat reading while the device was idle. The CTL NL6 Education Chromebook measured a temperature of 79˚ F. After 1 hour of the WebGL’s Aquarium test, the temperature had risen to 95˚ F in the middle of the keyboard, 97˚ F in the middle of the underside, and 92˚ F in the HDMI port. The absence of vents led to the unit’s heat reading measuring 96˚ F in the middle of the keyboard, 102˚ F in the middle of the underside, and 92˚ F in the HDMI port at the end of the test, more than 4 hours after the test start. While this temperature seems high, this is the temperature right by the processor and is not near where the user comes in contact with the device.

Battery Life. Battery life is an important aspect to consider when comparing Chromebooks. The test we use for battery life was the previously mentioned WebGL’s Aquarium test. We started this evaluation with a fully charged battery, WiFi on, and using 10 fish in the test. It took 4 hours and 52 minutes to fully drain the battery.

Performance Tests

Boot Up Speed. Chrome OS devices are known for their fast boot up times, and the CTL NL6 Education Chromebook does not disappoint. We timed 5 boot ups on the CTL NL6 Education Chromebook and finished with an average boot time of 7.9 seconds. 

  1. 7.98 sec.
  2. 7.66 sec.
  3. 7.57 sec.
  4. 8.16 sec.
  5. 8.11 sec.

Octane. We ran the Octane browser based benchmark tool 5 times, both plugged in and on battery power. Octane is available from the Google Developers website and measures the performance of JavaScript code found in modern web applications. There was no substantial difference between plugged in and battery mode. The device averaged 7,311 plugged in and 7,285 on battery power.

WebGL Aquarium. For our next test we used WebGL’s Aquarium, which measures the frame rate for different amounts of 3D fish that are rendered in the browser. The higher the frame rate, the smoother the motion displayed on the screen. The CTL NL6 Education Chromebook did well.

20 Tab Test. The next test involved setting the Chrome browser to load 20 different tabs simultaneously at startup to see how fast the page content would load. This device performed the 20 tabs test better than any Chrome device we have tested so far, only taking 38.75 seconds to load all the tabs. 

Note: This is the first time we have included this test in the body of the blog. However, you can compare the CTL NL6 Education Chromebook’s 20 tabs test to other Chromebooks in Straight Out of the Box-Chrome Device Comparison Sheet in Column Y.

Google+ Browsing. We also took a look at Chrome’s built-in FPS counter to measure frame rate and smoothness when scrolling through a site with dynamically generated content. For our test, we used a Google+ page. The counter was stable as content loaded and we experienced very little faltering when scrolling down the page. Frame rate stayed between 4-60 fps.

HD Video Test. To test HD video playback, we used the Nvidia PureVideo HD Test video on YouTube using the “Stats for Nerds” feature, which can be accessed by clicking on the video’s context menu. We played the video on 720p (the highest resolution that can be displayed at 1366 × 768), and video playback was very smooth with only 1 dropped frame for the entire length of the video.
