The Reasons Why Laptop battery power become less

Many Internet users and friends using a laptop may be found that the laptop battery power the more you use, the less it will be. Some specifically to professional information, suspected quality problems. In fact, this problem is normal.

To explain this problem, you have to talk about the structure of the battery. Before we understand the basic structure of the battery, laptop battery batteries and management chip. The batteries power storage “warehouse” management chip computing power and manage the charging and discharging process. The main elements that play a role in the batteries is lithium, which is an active element in order to ensure safety, only the state of ions in the battery. Inspiron 1525 battery shape similar to an ordinary battery, but often do laptop battery group. We often see the “core”, “six-cell battery refers to the number of batteries in the battery.

Batteries means that the capacity, the number of batteries of high capacity battery is generally about eight. The reason I talked about the batteries group is a group of batteries is the battery power to reduce the “culprit”. Batteries, the batteries in the group are not the same quality and discharge standards. After the discharge, in order to maintain voltage stability, management chip will detect the worst batteries charging protection. Often the past, the battery power will naturally be gradually reduced. This phenomenon, ready to use battery-correction function, this function can balance the batteries burden “work”.

I Should mention here the measurement of the battery, there are four kinds of common, but generally are integrated several ways to use one of the main methods of calculation, the rest of the supporting calculations to achieve the power calculation, and management.

The first one is the open circuit voltage measurements, this method is by measuring the battery voltage in the stationary state values ​​to calculate the remaining battery capacity, but due to the relationship between the voltage and remaining capacity in lithium-ion batteries still non-linear Therefore, the measured value of this method is not accurate, the vast majority of mobile phone batteries have adopted this method of calculation.

The second is called the Coulomb calculation method, which is calculated by measuring the battery charge and discharge current, the current value and time value of the product integral battery charge into the electricity and the release of electricity, Coulomb calculation is a more accurate power calculation;The third is the impedance measurement method, by measuring the resistance within the battery remaining Inspiron 1520 battery capacity value.

The fourth is a comprehensive look-up table method, set a table, voltage, current, temperature and other parameters input, you can query the remaining capacity of the battery.But regardless of which method, in charge management chip follow the “bucket theory”, to state the worst batteries subject to protection. Regular battery calibration to a certain extent to protect the battery, to extend the overall battery life.

Introduction Of HP G Series Notebooks

The G series notebook combines a Hewlett-Packard quality with an attractive design. The model that we know today is G42-372br version, this is considered an intermediate notebook but it has great results in demanding activities. For many users who are looking for a machine to do the basics with a good performance this is an option to be considered by the balance of its features and MSRP which attracts a lot.

The design of the G42-372br Hewlett-Packard is one of the main highlights of this team. The notebook is really nice, dark gray outer shell gives her a sober tone while the texture and gray accents a little clearer to give you a smoother appearance to the notebook becoming very visually pleasing. The model has at its base straight lines which further strengthens the professional air. By using the notebook is perceived the use of solid materials in its construction.

Also it is a lightweight equipment weighing 2.2 kg. This is the type of notebook that perfectly combines the use anywhere. Your screen has good viewing angle and 16:9 aspect ratio which gives us a more than interesting for viewing videos. The screen is fourteen inches with a maximum resolution of 1366 x 768 pixels. An interesting detail is the touchpad which is primarily necessary to calibrate but then gives us a great performance.

If we talk about team performance Hewlett-Packard comes with an AMD dual core Turion II P560, this processor has a clock of 2.5 GHz and AMD graphics card is a Radeon HD 6370 resulting in satisfactory performance most daily activities. During testing with equipment that is perceived performance could be even better if the notebook had 4 GB of RAM instead of 3 GB and a version of Windows 7 64-bit is present instead of the Windows 7 version Home Basic 32-bit.

Such restrictions were made for the price of the product is ultimately more accessible. In addition to this within the G-series models are more robust configurations. So nothing prevents the user can perform an upgrade to a RAM 8 GB such as the team to support this amount of memory, as well as the user can change the operating system present.

One bright spot of the notebook from Hewlett-Packard is the 500 GB hard drive with a speed of 7,200 revolutions per minute and usually in this type of equipment we record with a speed of 5,400 revolutions per minute. Meanwhile the battery is six cells and offers a range more than reasonable allowing 3 hours of use. If finally we talk about the relationship between cost and benefit the Hewlett-Packard G42-372br is an option to be considered by those who need a laptop that offers performance and flexibility in the daily mobility.

In a final conclusion on Hewlett-Packard team definitely has an excellent design and finish, an attractive price than a hard drive with a speed more than niche appeal, the disadvantage we have little memory and an operating system version little basic.

Mend Your Laptop Batteries Wisely

In this holy day, where everyone is busy and you want to do something hommia notebook increasingly popular. Such a computer, you can always carry with you everywhere. The main feature of all backup laptop notebook batteries supplied. It is necessary to a full working laptop batteries to complete. There are some cases where these batteries used in portable computers to fail and not work anymore. In this case it is necessary for the recovery of Apple a1012 battery used in notebook computers.

Laptop batteries are a little different than other batteries. Laptop battery is short, and if you change the battery, so the question can be expensive. It is much better Apple a1079 batteries for laptops, instead of using a fixed exchange rate. They decided that a laptop battery repair. Could it be that the cells with a laptop battery has not worked well, and the bad. In this case, it would be more economical to replace the cells.

You can nickel-cells, easily portable computer batteries go. Lithium-ion battery hybrid, it is necessary for manufacturers to complete a battery with a protective layer of cells circuit.During exchange provides a living force. This is due to the fact that we are all your critical data exclusion of the chain tension lost, so he could remain in the chain is useless.Here are some basic and important steps needed to restore the Apple a1175 battery.

Balance, always goes after the close of the second round of the medium voltage to the battery, secondary and off when the relationship is over, the replacement cells. Typically, the cell laptop battery with a simple line of bands seen them hold together. Use the laptop battery should be replaced when their inner work station no longer functions properly in this case, you should not change the battery, because even if the new battery, get a new cell. It would be better to drive the whole Apple a1061 battery replacement to replace.

We must remember terminal voltage of 10% to the second. To prevent this, we can go together to push the cells, it is the best way to get reliable service from the station. It is possible that memory cells, which I published, often with a nickel-hydride cells. So recharge the HP g70 battery, and try to avoid overloading loading and unloading cycle over and over again for 14 hours. It is a process that is required, use the chain again laptop batteries.
