Most of the power supplies for laptops is rather cumbersome, despite the progress and technological innovations point to the miniaturization of hardware. Add to that the energy, sometimes even absurd, to maintain access to a device like a notebook, going against the best practices for environmental sustainability.

YoGen Max is one of many creative solutions to the associated ecological and environmentally friendly technology. YoGen shows us that the world hi-tech can protect the environment. Let's see how! The instrument devised by YoGen is a power folding laptop, which can recharge your laptop without the need for external power.

The new Apple MacBook and MacBook Pro with the new Precision aluminum unibody chassis have debuted a few weeks. As often happens, the first models that come out of assembly lines may have some slight imperfection that requires action by the manufacturer. E'quello happened, for example, for defective trackpad , for which the Cupertino company has issued a fix immediately.

After some days, you hear rumors of another anomaly: while running the Cinebench 10 benchmark, which tests the performance of the processor in the rendering of three-dimensional subjects, reviewer and some users have shown a clear decline in performance when the battery is removed from its housing.

The enormous success Asus Eee PC, all over the world, has led many battery manufacturers to design and deploy high-capacity solutions for the home Netbook Asus. HKEPC made some tests with the A220 battery-P701H produced by ESI, 10.400mAh offers a capacity of about 6 cells, comparing with the classic 4-cell battery adapter, and 5.800mAh. ESI batteries are available in two colors (black and white) to match properly with the different colors of the Eee PC 701 and 900.

As frequently happens, the high-capacity battery raises significantly the weight of the small low cost laptop, which raised from 0.99 Kg to 1.12 Kg As for performance, HKEPC conducted two tests of "stress":
WiFi, Brightness 100%, Idle
WiFi, Brightness 100%, to 480p playback digital content

Among the many advantages that distinguish a notebook from a common desktop PC there is no doubt the portability, the freedom to use anywhere, any time, even if this power is strictly conditioned by the autonomy of the system. Leaving aside exceptional cases, the battery of a laptop has an average duration of about two hours, with a maximum of 10 hours of continuous work on some processors with ultra low power consumption. This record is destined to be broken soon, because, according to a recent study conducted in research laboratories in the United States Air Force, could be very near the birth of the first battery for notebook, running for 30 years!

This innovative battery is made up betavoltaiche cells, derived from semiconductors and use radioisotopes as the sole source of energy. From the natural decay of radioactive material derived the emission of beta particles that transform into electric power that can power a notebook for individual years.

The recall by Dell, to 4.1 million potentially defective laptop batteries, triggered a domino effect that quickly involved all the major notebook manufacturers in one of the largest product recall campaigns of all time: Apple , Lenovo, Toshiba, Fujitsu, and last, the same Sony have announced their commitment to a program for a total of about 10 million units recalled.

At the center of the controversy of lithium-ion batteries made by Sony Corp. that, as acknowledged by the same manufacturer, and as documented in widely circulated pictures and videos on the web, may go short circuit and catch fire because of tiny fragments of metal left in the cells as a production residue.
The CPSC (U.S. Consumer Product Safety Commission), which is working with Sony to produce a plan for global call for all batteries at risk, which emphasizes the danger of accidents is still low (around 50 cases out of 10 million notebooks sold the U.S.), though not be underestimated.

If you are a happy user of an Asus Eee PC 900 you really care what you present here, especially if you give it heavy use outdoors. Why tell you all this? Just watch.

Want more autonomy too your MacBook? Well Sahno comfortable that you company presents the solution to your problem. HyperMac This is a series of external battery ready for use with our range of MacBook laptops, both Air and Pro, which have PowerSafe connector, which can hardly find any external battery pack.

The HyperMac you buy it in different capacities, from 60Wh to 222Wh that will give you up to 32 extra hours of continuous work.

Available soon, even if for now only in Japan, Fujitsu LOOX R, a portable 12.1 inch whose main characteristic that its battery can last up to 12 hours.

The Fujitsu LOOX R / C70 uses an Intel Core Duo low voltage SU9300 at 1.2 GHz, so low that according to the manufacturer's own test, has gained autonomy in the battery to 12.6 hours. It is also noteworthy that use a SSD of 128 GB, besides other features like Bluetooth 2.1, fingerprint reader, RAM DDR3 2GB and a resolution of 1280 x 800 pixels on the LCD screen of 12.1 inches.

The company Proporta has released a new external battery, which makes it more portable laptop to our ....

It is quite light for its large capacity, and may be connected to any portable, take up between 16 and 19 volts through the 7 adapters attached.

How much autonomy you need for your MacBook? If the answer is "as much as possible and more," then you will be interested in these HyperMac. The invention is nothing more than an extra battery, developed by the company Sanha able to prolong the ongoing activity of the portable Apple for a whopping 32 hours. Although "whopping" is perhaps not the appropriate term, because after all this time the computer is running throwing smoke everywhere. Not to mention they are expensive and very heavy.

Moreover, this figure of 32 hours must be taken with many reservations, since manufacturers often stretch far beyond what we really can offer the time to practice. In fact, there are four models with different capacity: 60, 100, 150 or 222 watt-hours. Only with the last build additional maximum autonomy. Anyway, it is clear that we can give them enough extra life to your laptop, the MacBook's battery is only 37 watt-hours.
