There are many research projects worldwide that seek to create, to notebooks, batteries, more efficient, more yielding and more environmentally friendly than current ones. But while these developments arrive, may be useful to know some secrets of current batteries to make the most of. Next to that he spoke with Gustavo Lopez, director of the Computer Science Department, Faculty of Engineering, UBA, he explained, clarified, and advised upon the batteries of notebooks and the best way to use them: The batteries that are currently using notebooks the Lithium Ion (Li-Ion) or lithium polymer. The polymer are more efficient and allow designing thinner, but otherwise are similar to those of Li-Ion. One advantage of current batteries is that they can be recharged at any time, regardless of their level of charge.
One of the drawbacks of batteries today is that over time they lose capacity, but are not adequately usen.Cuidadas, these batteries can last between 500 to 1,000 cycles of loading and unloading. This number of cycles equivalent to an average user, two and a half years or three years uso.Atención Lopez says that the battery performance indicated by the manufacturers of notebooks are for the most favorable situations (using minimal resources) and are at least “optimistic.” One of the parties to the most demanding notebook batteries are the CD or DVD, that use energy from the operation of your laser and the motor that spins the discs.
Wireless transmissions (infrared, Bluetooth and Wi-Fi) also demand much energy, so it is recommended not disable while usen.El audio (even through headphones) is also a function of high consumption, especially if you use USB speakers that feed on the notebook.
For energy conservation must also consider that a brighter screen, more consumo.Señala Lopez that when choosing a notebook worth considering what use it will give the team. If it will be used for tasks that consume much energy without being connected to the mains, should choose a team with a lot of battery cells (the usually high-performance nine-cell), although it more pesado.Las batteries of notebooks are very sensitive to extreme temperatures, whether too high or too low, so we recommend using the notebooks at low ambient temperatures and away from heat sources. This will extend the useful life of baterías.Para prolong the service period of the batteries is also recommended whenever possible to avoid the charge level drops below 20%.
If you use the notebook plugged in, removing the battery. Keep it in place, exposed to the heat that might affect your ability to retain power, and exposed to “stress” of being permanently 100% charged.
He explains Lee, “A battery whose charge is maintained at 100% at 60 ° C over a period of 100 days, retains only 60% capacity, reducing its useful life exceeding one year. I therefore recommend removing the battery when I use my computer plugged in, although some dust may enter into the slot will be empty. “Finally, if subject to prolonged periods of inactivity of the battery, Lee recommends storing it at 40% charged in a cool place. Everything written here is also true for netbooks (small notebooks too) that use batteries identical to notebooks, only smaller and therefore lighter. The “secret” of netbooks is is its microprocessors, which consume little energy. “Ten times less than other processors,” says Mariano Yacovino, Intel, about Atom processors for netbooks of their company.

Does anyone remember the concept we showed at Microsoft Courier Applesfera? Do not deny it, the ideas we saw in that video were pretty good and even conceptual, it would be nice to see something in reality.
But if your Mac have a program that can do very similar things. His name is NoteBook and part of a very similar concept used by Microsoft: a “disaster box” where you can organize our ideas in an original and much as could be done directly on a notebook.
The program has some templates depending on the task that we perform, so we only have to edit the content. All templates include an automatic rate in the first tab and from there we can divide our “notebooks” in sections. Once created you can add sections all the pages you need for each, add photos, post-its, text, arrows and flow charts … etc. Too bad they can not be used from a Wacom.
Also included is an integrated browser, so that pointing is not lost among a pile of leaves as in a real book. The program is very attractive visually and whether to put a paste of its high price would be $ 49.90, 35 euros. Finally you can try the program for 30 days, so it will be a great way to discover whether it is worthwhile to pay for it.
