Lenovo Yoga 900 (Core i7 / 16GB / 512GB): Performance Tests One downside of the speakers' bottom-mounted design is that audio can shift greatly from quite airy to sometimes harsh depending on what surface the system is resting on. However, when I listened to Drake's "Hotline Bling," I liked the crisp sound of the staccato percussion and richness in the mids and vocals. Unfortunately, even after playing around with the included Dolby Audio app, I found the bass was lacking. The Yoga 900's stereo JBL speakers are positioned behind two grilles and feature Dolby DS 10.0 Home Theater Certification. The Surface Book scored a superb 0.57, while the Dell Inspiron and the Spectre x360 were also better, at 1.16 and 1.25, respectively. The Yoga 900's color accuracy was similarly strong, but not at the head of the pack - it earned a Delta-E rating of 2.77 (closer to 0 is better). That puts it ahead of the Dell Inspi(88.6), but behind the Spectre x360 (103.2 percent) and the Surface Book (98.5 percent). The Yoga 900's color range was a tad short of covering the entire sRGB color spectrum, scoring 93.2 percent. The Dell Inspiwas only slighter more luminous, at 316 nits. We measured the Lenovo at 284 nits, which makes the Surface Book and the HP Spectre x360 13 significantly brighter, at 387 nits and 339 nits, respectively. The biggest weakness of the Yoga 900's display is its brightness, which is slightly below average. When I watched the trailer for Quentin Tarantino's The Hateful Eight, the rich, goldenrod lapels on Samuel L Jackson's jacket provided a great contrast to his dark winter coat. Images remained bright and colorful even at very wide angles. Ideally, Lenovo would have made the touchpad a little wider, because a little more mousing real estate would have been nice, and the silky coating is so seductive I just want more of it to touch.įeaturing a pixel-dense 3200 x 1800 13.3-inch display, the Yoga 900's screen is supersharp and does a wonderful job of showcasing photos and movies, no matter which mode it's in. Using two fingers to scroll through Web pages was supersmooth, and the system never confused left or right mouse clicks during normal use (unlike the Surface Book). The one-piece touchpad measures 3.5 x 2.5 inches and features a soft-touch finish across its top. Users with sensitive wrists will find that the soft-touch deck makes their hands feel more comfortable while typing. This allowed me to hit 81 words per minute on my first run through 's typing test, which is actually slightly higher than my typical 75- to 80-wpm range. The keys have a short travel distance of just 1.1 millimeters, but the relatively springy response and 58-gram actuation weight help combat any sense of deadness when bottoming out. Even the 13-inch MacBook Air, which is often thought of as the leading thin-and-light laptop design, is a touch larger and heavier, at 12.8 x 8.9 x 0.11-0.68 inches and 2.96 pounds, and it's not even a convertible. The Yoga 900's 3200 x 1800-pixel screen is super sharp and does a wonderful job of showcasing content no matter what mode it's in.Īt 12.75 x 8.86 x 0.59 inches and 2.8 pounds, the Yoga 900 is ever-so-slightly smaller, and noticeably lighter, than other 13-inch convertibles, including the HP Spectre x360 (12.79 x 8.6 x 0.6 inches and 3.26 pounds), the Dell InspiSE (13 x 8.7 x 0.75 inches and 3.63 pounds) and Microsoft's Surface Book (12.30 x 9.14 x 0.51-0.9 inches and 3.34 pounds). There's a power button with a small white light, a tiny recessed button for triggering Lenovo's OneKey Recovery software, and another button to toggle the system's rotation lock on and off. Lenovo includes a shadowy capacitive-touch home button in the fat bezel beneath the display, while the rest of the buttons are located on the right side.
