Netbooks: The battery lasts longer now

280

Great stamina already had the older – generation netbook . The new set top it: The Pine Trail Netbooks kept in thinkpad t43 battery 30-45 minutes longer than comparable with previous models . The MSI Wind U135 with 48- watt-hour battery ran for Internet access via wireless just under six hours. brought the HP Mini Note with 58- watt-hour battery test on it in 8:35 hours. The Samsung N220 held out thanks to the 63- watt-hour battery even 10:04 hours.

Even more stamina showed the Asus Eee PC 1005PE : When Wi-Fi test he reached 10:19 hours, although he is only equipped with a 48- watt-hour battery. The Asus device was thus the most economical in the test. But can be the result not directly comparable with those of the other Pine Trail Netbooks : For wireless testing, the PC World is in fact the brightness of the Netbook screens to 100 cd / m². It can thus be in a normally lit room read easily . But the Asus netbook managed only a maximum of 96 cd / m². Also at the second test of the battery – dim screen the Asus netbook helped to a lush period of 6:20 hours. This test checks the PC World , as long as the Netbook , when playing a movie from the hard drive hold out. Here the image is set as light as possible : learn how to make films and photos the best impression. Until Asus released a BIOS update that gives the Eee PC 1005PE to a higher brightness, PC World , the device is therefore devalue the Pavilion DV1000 battery time.

The Samsung N220 outperformed the Eee PC 1005PE with 6:44 hours, and the HP Mini Note was 210 for six hours. But in both netbooks puts a larger battery, which makes them a little harder. The MSI Wind U135 with 48- watt-hour battery ran 4:19 hours.

Thus the new netbooks beat at games & HD movies

The Pine Trail Netbooks are therefore a bit more economical than their predecessors. Much faster they are not. The new processor Atom N450 for example, offers a little more processing power than its predecessor Atom N280 . In the tests, the 3D velocity of the new netbooks cut but twice as good as the predecessor Windows XP. But that was less in the new GMA 3150 graphics chip than 7 to Windows

Still, for 3D games and the new netbooks are far too slow. The Aero interface of Windows 7 could be the new netbooks well : it makes the Windows interface by program windows with a transparent border and shadows not only look elegant, but will in many windows open even better overview. But in the Starter Edition of Windows 7 Aero is not included .

The playback of high resolution videos overwhelmed by the way , the new netbooks. Although it is on such a device is rarely high- definition ( HD) movies to play from an external Blu -Ray drive. But the Internet is true more often on high-definition video , even with Youtube. Those who absolutely need HD to the netbook , it must be with the Minis – Ion graphics from Nvidia attack , which in 3D and HD are stronger than the Pine Trail representative. However, the ion netbooks running on battery power much shorter.

The HP Mini Note 210 was the fastest of the new netbooks. In it lies a hard drive that operates at 7200 revolutions per minute. All other netbooks use a hard drive with 5400 rpm. The HP netbook brought in some tests a small rate increase , which occurred at the expense of the duration.

Researchers are looking for the super battery(B)

March 19th, 2010

A key problem is to concentrate as much as electrical energy in the smallest space. Researchers at the Fraunhofer Institute for Chemical Technology (ICT) in Pfinztal near Karlsruhe, therefore, attempt to replace conventional graphite electrodes with materials from tiny, only a few hundred nanometers thick carbon tubes and fibers. This would dramatically increase the inner electrode surface. Normally, lithium ions move only between the graphite layers of the host lattice. A task that is called intercalation. The Nanokohlenstoff from Pfinztal is also different here: “If nanotubes are deposited lithium-ion addition to the edges and surfaces of material layers. Nanotubes can also be manufactured so that a much larger proportion of occupied Interkalationsschichten of lithium-ion Pavilion DV1000 Battery ,” says Jens Tübke head of ICT at the Department of Applied Electrochemistry.

Meanwhile, the researchers were able to increase the discharge capacity of nano-batteries to about 800 milliampere hours per gram (mAh/g). Classical graphite apple a1185 provide only 300 mAh / g. Nor is the production of micro-carbon nanotubes-consuming and expensive.

Ten times more lithium ions per gram of silicon can store as an electrode material in comparison to graphite. To the chagrin of the researchers, however, increased fourfold while the original volume of the brittle semiconductor materials. The result: After a few charge cycles to show cracks. Here, too nanostructures to solve the problem. For example, researchers at Stanford University are experimenting with micro-fine silicon tube as an electrode material of pavilion zv6000 battery. In the nanofibers mechanical stresses during loading and unloading can survive obviously much better than normal silicon crystals. In addition, the mini-tubes can be produced with the chip production process from relatively inexpensive.

In the laboratories of Stefan Koller, Institute of Chemical Technology of Materials at the Technical University of Graz are also lithium-ion Pavilion ZV5000 Battery tested with silicon electrodes. The Austrian researchers battery is however a containing silicon gel which is deposited on graphite as a substrate material. “It has graphite as a buffer to absorb the large volume changes of silicon in the ion absorption and emission,” said Koller. The new material could thus save an unchanged lifetime, more than double the amount of lithium ions. Challenge, however, remains the poor density of the materials in the electrode.

High-performance TravelMate 2440 series battery should base on lithium-ion plating,and are used for electric vehicles such as energy, the relatively long time to load the batteries can quickly be the Achilles heel of the technique. Until now, battery experts have always assumed that lithium ions during charging is not fast enough to move through the respective electrode material. A computer simulation, carried out the Gerbrand Ceder, Massachusetts Institute of Technology (MIT) in Cambridge (USA), but then placed near the opposite: the example of the standard material lithium iron phosphate (LiFePO (-4)) showed cedar that lithium-ion moving within the electrode downright brisk. But they are thwarted by the limited number of access channels in the crystal lattice, which are also difficult to reach. The result is a jam of the charge carriers.

Calibrating a MacBook or MacBook Pro battery

March 16th, 2010

To Calibrate the battery in your MacBook or MacBook Pro every month or two to keep your battery functioning at its fullest capacity.

To calibrate the battery:

  1. Plug in the MagSafe power adapter,and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the thinkpad t61 battery icon in the menu bar indicates that the battery is fully charged.
  2. Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
  3. Disconnect the power adapter with the computer on and start using it with Pavilion DV1000 Battery power. When the battery’s charge gets low, you’ll see the low battery warning dialog on the screen.
  4. Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery’s charge gets low and before the computer goes to sleep.
  5. Turn off the computer or allow it to sleep for five hours or longer.
  6. Reconnect the power adapter and leave it connected until the Pavilion ZV5000 Battery is fully charged. You may use your computer during this time.

Repeat the calibration process every two months, or so to keep the battery fully functioning. If you use your MacBook or MacBook Pro infrequently, it’s best to recalibrate the pavilion zv6000 battery at least once a month.

If you purchased additional batteries, repeat the calibration process with those batteries as well.
