Notebook battery review

Has been upgraded to Microsoft’s Windows Vista operating system, notebook computer users should probably disable some of the fancy new operating system, image display, as compared with the Windows XP operating system, running Vista operating system, you may shorten the laptop battery Sony VGP-BPS2 life.

As the Vista operating system to configure the high-end computer processors, graphics cards and memory requirements of higher machine power requirements and thus a corresponding increase, so battery life will be shortened accordingly. Microsoft’s Vista operating system in the new version added a number of novel visual effects such as transparent Aero windows dell inspiron 1721 battery, and the performance of digital media center has also been improved VGP-BPS9/S. Vista Enterprise Edition operating system, has been listed in the last month, the consumer version of the Vista operating system, scheduled to be officially released next month.

If the computer and hardware manufacturers will now become a cash cow Windows Vista look, this can not be overemphasized, because Vista operating system, computer hardware requirements are very high. However, the computer power increase is a price to pay to BTP-58A1.

A Microsoft spokesman has confirmed that the user can use the Vista operating system power management software tool to disable or reduce the image display quality, so as to ensure Vista operating system, battery life can go back to XP operating system, battery Sony VGP-BPS5 life level . But she claimed that the image display quality, battery life on the computer than on the impact of other hardware is slightly smaller.

AMD’s chief technology officer Phil Hester in the company’s analyst in New York last week at the annual meeting, said: “In the Vista operating system to run a specific application of the computer resources required for the operating system than XP when running under required much more computer resources with powerbook G4 ac adapter. Therefore, the computer’s battery must have more power, otherwise the battery will be as long-term high-power run and shorten its life. ”

Dell also said that Vista operating system, a greater demand for computer resources, computer battery life will be shortened.Dell spokesman Yilaweilian e-mail interview, said: “If the full Aero mode, run the Vista operating system, and Vista systems equipped with power adjustment setting is not open Acer Aspire 3000 battery, then the computer power demand will increase a lot thus causing a great impact on battery BTP-58A1 life. That is, if the user in battery optimized mode (using non-3D port) running under Vista operating system, then we believe that the battery life might be with the XP system does not run too much a big difference. ”

Microsoft spokeswoman Kristin Farmer, said: “Although Windows Vista’s Aero theme and components of the system using the system resources is indeed better than previous versions of Windows systems are a little more, but its battery life of the related impact is minimal The Toshiba PA3399U-1BRS. “Farmer said: “Microsoft is working with equipment manufacturers to ensure their device drivers in accordance with optimal performance and optimal allocation of energy-saving point of view. We recognize that battery life is not just Microsoft’s side of the issue, it is also linked to our partners HSTNN-LB31 in decision-making. “

The birth of the day from the laptop, the battery of this “servant” had been accompanied on its side, there is no battery, it can be said can not be called the laptop “mobile computer.” With the notebook performance and technology continues to improve with the improvement, it is the “servant” of the “quality” is also getting higher and higher, from the past, nickel-chromium batteries, nickel-metal hydride batteries to now have been using lithium batteries may be popular even after the fuel the dell inspiron 1721 battery, few people care about this and notebooks are closely related to what - the battery, then let me work with you to look into the laptop battery.

The classification and distinction between the battery

In general we use there are three kinds of batteries, 1. Nickel-chromium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Ni-Cd NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI like sony VGP-BPS8, in recent years, In the notebook field has also been a fuel cell, its only by-product of water and heat, no noise, the basic pollution-free, efficient power generation systems in general higher than the multi-reach 43 ~ 58%, if the heat produced by the reaction utilization, efficiency can be up to 80%! Is a clean and environmentally friendly power. Because of its technology was not perfect, there are still many problems to be solved, and now it is in terms of cost, size, weight, ease of access to fuel, both absolutely can not and traditional lithium batteries and polymer lithium battery to compete.

Notebook computer with fuel cell, fuel cells seem like a lot

NI-CD Ni-Cd batteries because of their age is too early, so have many of the shortcomings of a headache, such as: bulky, heavy weight, capacity, small, short life, there is memory effect, etc. (useless), and now no longer in use. Now mainly NI-MH battery Ni-MH and LI lithium two kinds. Ni-MH battery which is also active in the battery industry, 1:00, compared to other batteries, nickel-metal hydride batteries as Sony PCGA-BP2NX to be more environmentally friendly some, it is also by far the most environmentally friendly battery, while the lithium battery Well, with a small size, light weight, large capacity, low memory effect, charging time is short, etc., well received by customers love, but you will often see the back of the battery properly abandoned and handling lithium batteries instructions? Because the lithium batteries to discard will cause environmental pollution.

Now that the market price of the original equipment batteries are very expensive, generally place around 1000-1500, so some of my friends started to replace the battery, through their own batteries to achieve the purpose of extending battery life. Theory should, it is possible, but due process reasons, the batteries are generally used ultrasonic welding, there is no gap, it is difficult apart, even if the hardware is also very difficult to disassemble a close to 319411-001, I see the electronic Shangyuan to the two hands are their own battery replacement batteries and then sell finished, the battery can be a combination of Office, it is clear to see there are 502 marks, after gluing, even with batteries, replace more time to find a match difficult.

And some laptop batteries such as IBM, there is a protection circuit inside the Dell Latitude D800 Battery, the event of a failure to make the internal temperature is too high, will automatically cut off, has a protective effect, if the replacement batteries, when accidentally damaged piece of the circuit lead to disastrous consequences . So I still do not recommend to replace batteries on their own, even if the need to be replaced is also looking for professional and technical personnel to assist the replacement.

Portable equipment with high-energy needs is powered with battery packs in which two or more cell are connected in series. Figure 1 shows a battery pack with four 1.2-volt cells in series. The nominal voltage of the battery string is 4.8V.

Adding cells in a string increases the voltage but thecurrent remains the same.High voltage batteries have the advantage of keeping the conductor and switch sizes small. Medium-priced industrial power toolsrun on 12V to 19.2V batteries; high-end power tools go to 24V and 36V to get more power than Dell Inspiron 1721 Battery. The car industry will eventuallyincrease the starter-light-ignition (SLI) battery from 12V (14V) to 36V, better known as 42V. These batteries have 18 lead-acid cells in series. The early hybrid cars are running on 148V batteries. Newer models feature batteries with 450-500V; mostly on nickel-based chemistry. A 480-volt nickel-metal-hydride battery has 400 cells in series. Some hybrid cars are also experimenting with lead acid.

42V car batteries are expensive and produce more arcing on the switches than the 12V. Another problem with higher voltage batteries is the possibility of one cell failing. Similar to a chain, the more links that are connected in series, the greater the odds of one failing Sony PCGA-BP71. A faulty cell would produce a low voltage. In an extreme case, an open cell could break the current flow. Replacement of a faulty cell is difficult because of matching. The new cell will typically have a higher capacity than the aged cells.

Figure 2 illustrates a battery pack in which cell 3 produces only 0.6V instead of the full 1.2V. With the depressed operating voltage, the end-of-discharge point will be reached sooner than with a normal pack and the runtime is severely shortened.Once the equipment cuts off due to low voltage, the remaining three cells are unable to deliver the stored energy. Cell 3 could also exhibit a high internal resistance, causing thestring to collapse under load Pavilion dv6000 Battery. A weak cell in a battery string is like a blockage in a garden hose that restricts water flow.Cell 3 could also be shorted, which would lower the terminal voltage to 3.6V, or be open and cut off the current. A battery is only as good as the weakest cell in the pack.
