I never give the batteries in my notebook much thought. I swear, if I have to and forget about it. That changed a few weeks ago, when I could not find at home to get, and was reduced to working at an Internet café. There’s much competition for seats with outlets here in the Blogger-heavy San Francisco, I made sure that my notebook was loaded before I left the house.

Ooops. Ten minutes will be shut down and use my PC. It was in power. I pay the same happens again. Yes, it was the battery DOA. Humble as a battery can, you will not get much done without a good job.

After shelling out a new, I asked around and found a Dell Studio 1537 battery expert to give a solid tips, notebook Akkusn has a long and energetic life.

1. Keep the notebook in his lap
“Akkusn like to stand at room temperature, and I do not mean like a space in the tropics,” said John Wozniak, a distinguished technologist for Hewlett-Packard.

Although most portable notebook PCs, we call that today’s high-performance notebooks are not designed to sit on his lap. Sure, they get warm and you can begin to feel uncomfortable after a while, but that’s not the point. Most notebooks have designed legs on the bottom, to allow some air flow underneath. If you are working on a hard surface like a desk, there is no problem, but if the notebook is sitting on your lap, it sinks down a little bit and air can not circulate.

This can be a real problem quite quickly if you are watching a movie because you play a DVD contains both the CPU and the graphics chip is pretty busy and warm. You can fly the problem by working on the folding tray table if you, or spending $ 20 or so on a pad stiff enough to prevent the notebook a little distance.

Keep doing clean the air vents on your notebook much to keep heat from building. A simple but effective method is a can of compressed air blown in from any computer store or hardware store and buy the dust.

2. A little help unplugging
Not so long ago, the most notebook Akkusn NiCads, ie, nickel-cadmium basis. The design had a pretty major flaw: if the Dell XPS M1530 battery was consistent before you pay most of the way down, it would not take a full charge no matter how long it was plugged in, that was called battery memory, and the solution was to drain them every now and then leave and be sure she got a full charge.

Today’s lithium-ion Akkusn not have these problems, so do not worry about the charge before the power of the gauge is hovering low, says Wozniak.

However, so they plugged in all the time is not a good idea either, although it is tempting. In fact, the batteries, the user is an uninterruptible power supply, so if you expect to follow the current unexpected, it makes sense to keep the battery in position when the machine is plugged

But to do that much and the Dell Latitude E5400 battery is removed. To remove it, if you do not plan unplugged for an extended period of work. The best way to a lithium-ion battery is stored, allow it to about 60 percent of its load and delete to be sure that you are in a pretty cool place, he says.

3. Understand the product information
Do not forget to follow battery technology is not Moore’s Law. After covering the technology industry for a while, I have heard many promises, which came a real breakthrough in battery technology. Now it was not – and Wozniak says he can not be seen in the distance.

That’s not to say Akkusn have not improved, they have come up with a gain of about 6 to 8 percent per year, he adds.

Generally, more cells mean more power per battery, but that does not mean a 12-cell battery you will receive 33 percent more run time as a nine-call battery. For example, rated a 9-cell battery, 3.0 amp hour, almost the same energy as a 12-cell Dell Latitude E6400 battery with 2.2 Ah reviewed.

Rather than do the math, it is easier to check the specifications and compare the number of watts, easier to find numbers. As you would imagine, the actual duration of a battery’s output is dependent on what makes the notebook. Applications such as video use a lot more juice than writing or surfing the Internet, of course.

No electronics product will last forever, but treated well, the batteries hang in there for at least two or three years.
