  2. Data sheet

Sony VAIO VGN-Z21MN in the test. The notebook comes with the Nvidia GeForce 9300 M GS graphics solution. Thus, the Sony at the 3-D gaming Fujitsu played more than twice the power than about those in the same class brings Siemens LifeBook S6420 and Samsung X 360 U9300.

So, already a game can be venture, although at current d hits or high resolution external displays the richness of detail must be reduced slightly at the screen resolution of 1366 x 768 pixels. Who fears the worst for the endurance in the face of the graphics chip, can be reassured at the Sony.

Left, is the switch is placed below the display from the position of “Speed” in the “stamina” position, so the notebook on the power-saving switches chip set graphics GMA X 4500 to Intel. the 3-D performance goes back then of course accordingly. This switching even without new booting in normal mode works thanks to special Windows Vista drivers.

“Stamina” vs. “Speed”: slight performance differences

While the “stamina” mode in 3-D games makes less than half of the speeds, the performance differences with 0 to 10 percent on the border of visibility are low in all other areas.

The Sony VAIO with the speed of most larger laptops can complete the tasks occurring in everyday business office, Internet, photo – and video editing and co..

The VGN-21 has both a DVD drive for reading and burning built as also the HDMI output for digital image output. It must fit only for Blu-ray discs. The available capacity of the hard drive, the Sony with nearly 180 GB can shine, the screen’s also has an advantage compared to the Competitors box lead by his mirror poverty with high contrast.

The 1366 x 768 pixel sound, however, a maximum before the amount after a real resolution advantage over around the 1280 x 800 pixels from Fujitsu Siemens and Samsung. Fact is except for films in the 16:9-format in most cases representing supports 1280 preferable, because with her less vertical scrolling is necessary.

The interfaces requires the Sony with two USB ports, to do this it has a FireWire connector. The Sony supports the standard ExpressCard in the narrow version, which is now established especially in UMTS data cards. In addition, it supports Wi-Fi to the draft-N version, but not Bluetooth.

Sony VAIO VGN-Z21MN test: endurance

Keyboard and trackpad is at a high level what’s volume and frequency of use of the fan, the candidate is not completely silent, a real troublemaker is not he but also.

Inpuncto endurance can boast the Z21MN outstanding values: under normal working load in practical display brightness of 100 candelas per square meter last esmaximal six and a half hours. Only those who held the operating mode switch to “Speed” display energy-saving “stamina” are, must faster to the socket: here the battery is empty, after less than five hours even if 3-D performance is not required.

Bottom line: When it comes to a notebook good in every, the Sony VAIO VGN-Z21MN is the first choice that, brilliant also thanks to the possibility to switch between low-power and high-performance graphics in the endurance, without having to provide computing power or handling observation. The equipment is located at a high level.
