long battery life, but performance falls short
Welcome to a laptop battery specialist of the Hp laptop battery
After years of getting little respect, Chromebooks are finally on the rise (at least in schools), which means every major PC maker is trying to get in on the action. That includes chip makers too, like NVIDIA. Though the company previously shied away from Chrome OS devices, it's now pledging to power a whole range of different Chromebooks with its Tegra K1 chip, each of them promising long battery life and more graphics muscle. The Acer Chromebook 13 is the first of the bunch, and while some of you might be Chromebook'd out, we were actually excited. Here was a $300 laptop boasting at least 11 hours of battery life, a 1080p display option and enough horsepower to clobber Intel at things like gaming and rich websites. As it turns out, it was all just a little too good to be true.
As the first Chrome OS device with an NVIDIA Tegra chip, the Acer Chromebook 13 isn't as powerful as promised. Still, it manages to redeem itself with long battery with like Hp AT901AA battery, Hp HSTNN-DB0G battery, Hp HSTNN-I71C battery, Hp Mini 5101 battery, Hp Mini 5102 battery, Hp 579027-001 battery, Hp HSTNN-N50C battery, Hp HSTNN-IB72 battery, Hp Pavilion-dv4 battery, Hp Pavilion-dv5 battery, Hp Pavilion-dv6 battery, Hp Pavilion-dv6t batterylife, a sharp screen, a comfortable keyboard and, most importantly, a fair price.
Looking at the Chromebook 13's spec sheet, you'd assume design was the main place where Acer cut corners. And you wouldn't exactly be wrong. The machine is fashioned entirely out of plastic, with certain parts, like the bezels and bottom side, actually feeling a bit rough to the touch. Next to the Samsung Chromebook 2, which sports a fake-leather lid, this is clearly the cheaper of the two. Acer's model is also about a quarter-pound heavier, at 3.31 pounds and 0.71 inch thick, versus 3.06 pounds/0.65 inch for the Chromebook 2. If you want something as light as a 13-inch Ultrabook, you better be prepared to pay an extra $100 for the Samsung.
Still, compared to Acer's older Chromebook, the C720, this is a marked improvement. Whereas the 11-inch C720 is small and cramped, like a netbook, this 13-incher is broader, with a more spacious keyboard and a wide touchpad to match. The design is simpler, too. Yes, it's plastic, but the all-white look is at least clean and modern-looking. Also, not that the lid and palm rest pick up scratches easily, but if they did, they'd be all but invisible thanks to the white paint job.
Even if Acer's design here is on the plain side, it's all worth it when you see the display. For all the scaling-back Acer did with the rest of the chassis, the screen here is quite nice for a Chromebook, especially one this size. What we have here is a bright, 1,920 x 1,080 display with a matte finish that allows for some relatively wide viewing angles, especially from the sides. Even so, there's only so much you can dip the lid forward before the panel starts to wash out. This, I'm afraid, is a problem across all Chromebooks -- even on models with sharper, 1080p screens, I've yet to see one with truly good viewing angles. Chalk it up to PC makers trying to keep hardware costs down, I guess.
As I hinted earlier, the keyboard here is nice and big -- a perk of choosing a 13-inch Chromebook over an 11-inch one. That means all of the major keys (Shift, etc.) are amply sized and easy to strike without looking. That said, the keys don't seem to have much more travel than they did on the C720, which means I once again found myself having to re-type things after my key presses didn't register the first time. Even so, I found it usable, and I think you will too. On a brighter note, the touchpad is nice and big, and responds well to both single-finger tracking as well as multi-touch gestures like pinch-to-zoom.
Around the edges, the Chromebook 13 has all the same ports as competing devices, which is to say it sports two USB ports, an HDMI socket, a full-sized SD card slot and a headphone jack. You might not know it at first glance, though: Whereas most machines stack all the ports along the right and left sides, the Chromebook 13 has a USB and HDMI port tucked around on the back, out of sight. So, it might seem at first like Acer was stingy -- that it could only be bothered to include one USB port, a memory card slot and an audio port. But that's just the extent of what you can see when the machine is in front of you.
To recap what I said in the very first paragraph of this review, the Acer Chromebook 13 is the first Chrome OS device to make use of an NVIDIA Tegra chip -- specifically, the quad-core K1 processor already used in some tablets. To hear NVIDIA tell it, the chip is better than Intel's Bay Trail processors (the ones inside most Chromebooks) in every way possible. That's not quite true. In single-thread JavaScript tests like SunSpider, Mozilla Kraken and Google Octane, the Chromebook 13 performs in line, if not slightly worse than, Bay Trail Chromebooks like the Lenovo N20p. In daily use, it cold-boots in nine seconds and can sign off in about four -- not bad for a Chromebook, but not exceptional, either.
NVIDIA, for its part, doesn't deny the less-than-impressive JavaScript results, though it's quick to suggest some WebGL tests instead that are more likely to showcase Tegra's graphics muscle. Indeed, in an animated Gangnam Style video (don't ask), Acer Chromebook 13 runs between 50 and 60 fps, while the Lenovo N20p's Bay Trail processor could barely crack 24 fps. (I used Google Chrome's built-in frame-rate counter.) In the benchmark Oort Online, the Chromebook 13 scored an average of 4,007, compared with 1,300 for the N20p. In this 3D Earth model, Acer peaked in the high 50s, with frame rates mostly hovering in the 30s and 40s; with the N20p, frame rates stayed in the 20s and 30s, depending on how fast I spun the globe around. Finally, in NVIDIA's own multitasking test, which involves running a Google Sheets macro with music streaming in a different tab, I saw a 21 percent improvement in speed on the Acer Chromebook 13: 46 seconds, down from 58 on the Lenovo N20p.
This would be a good time for me to back up and put all that in plain English. What it comes down to is this: The Acer Chromebook 13 does well on some tests, particularly the ones that NVIDIA itself recommends. Otherwise, its performance falls in line with the very Bay Trail-powered machines that NVIDIA claims to beat. Either way, the Chromebook 13 doesn't feel faster than other Chrome OS devices in real-world use. It doesn't feel slower either, but that's not saying much, given that Chromebooks generally aren't known for their stellar performance. On the plus side, the machine stays nice and quiet, and it runs cool. Ultimately, if you buy the Chromebook 13, it should be because of the price, the 1080p screen, the long battery life -- not because you're expecting superior computing power.
NVIDIA's performance claims may have fallen short, but the battery life here is just about as long as promised. On the 1080p model, which is rated for up to 11 hours, we got 10 hours and seven minutes of continuous video playback. That's admittedly a grueling test, too, so I have no doubt that with a lighter workload and more conservative brightness settings, the machine could've made it to the 11-hour mark and then some. If you go with the lower-end Chromebook 13, which has a 1,366 x 768 display, you can expect up to 13 hours of runtime, according to Acer. I unfortunately didn't get to benchmark one of those, so I can't vouch for that particular performance claim. If it's true, though, that would make it the longest-lasting Chromebook on the market.
