Welcome to a laptop battery specialist of the Dell Ac Adapter
Click to EnlargeThe tablet itself has a handful of ports on its bottom surface, including a microSD card slot, a 3.5mm headphone jack and a proprietary docking port that either connects to the dock or directly to the charging cable. The keyboard dock provides two USB 2.0 ports and one full-size HDMI connector but, disappointingly, no SD card slot and neither of the USB ports supports USB 3. The Toshiba Portege Z935 has both USB 3.0 and Ethernet ports.
Click to EnlargeThe front-facing 720p webcam on the Envy x2 took relatively bright but extremely noisy images of our face, even when we stood directly under an overhead light. The 8-MP rear webcam captured sharp colorful images with battery such as Dell Latitude D820 Ac Adapter, Dell Latitude D500 Ac Adapter, Dell Inspiron E1505 Ac Adapter, Dell Inspiron E1405 Ac Adapter, Dell Inspiron 600M Ac Adapter, Dell Inspiron E1705 Ac Adapter, Dell Latitude X200 Ac Adapter, Dell Inspiron 2650 Ac Adapter, Dell Inspiron 2600 Ac Adapter, Dell Inspiron 2500 Ac Adapter, Dell Inspiron 7500 Ac Adapter, Dell Latitude CS Ac Adapter, both in natural light and in dark indoor situations. An outdoor image taken on a cloudy day showed fine details like gravel on the pavement and leaves on the ground though colors were a little dull.
An indoor image we shot of an infant in direct sunlight was crisp with accurate pink skin tones and vibrant colors like the stripes in his pajamas or the blue and white in his blanket. A low-light, flash picture of a child's bouncer seat was also colorful. A 1080p video of cars rolling down a highway at dusk had smooth motion but rather dull colors.
Click to EnlargeWith a 1.8-GHz Intel Atom Z2760 CPU, 2GB of RAM and 64GB of slow-writing Flash memory, the $849 HP Envy x2 performs like a netbook. In our testing, the tablet had no problem browsing the web, playing full HD videos or even playing Windows 8-style games like the third-person shooter Judge Dredd versus Zombies. However, the system struggled with processor intensive tasks such as transcoding video or crunching spreadsheets, and it suffered noticeable lag in the Fresh Paint drawing program.
On PCMark07, a synthetic benchmark that measures overall performance, the Envy x2 scored a modest 1,428, far below the 2,872 tablet average but a little bit higher than the 1,305 provided by the Acer Iconia W510, which has the same CPU. The Envy x2 scored 1,336 on Geekbench, another performance test, about on par with the Iconia W510's score of 1,324 but behind the 1,698 tablet average and less than half the 3,214 ultraportable notebook average. The $699 Core i5-powered Acer Aspire V5, which has a 15.6-inch touch screen, scored 2,377, while the Core i5-enabled Toshiba Portege Z935 scored a much-higher 5,486.
The 64MB SSD booted the system in 14 seconds, excluding the time we spent typing in our password. That time is faster than the 20 seconds it took the Acer Iconia W510 and the 30 seconds it took the Microsoft Surface, but slower than Acer Iconia W700's time of just 10 seconds.
