Notebook PCs have become a fashion, more and more people to give up the desktop, start selecting laptop computers. Not only on its portability has great advantages, make it a more integrated hardware footprint smaller. The most important reason is the use of rechargeable laptop battery is one of the advantages relative to the desktop, it can greatly facilitate a variety of environments in the use of laptop computers. And with the progress of the battery level of technology, long battery life of notebook after another. Today, let's talk about the laptop battery that point thing.AC adapter laptop keyboard lcd screen

 

We all know that as consumables, laptop battery life is. So select the notebook, an important factor is to see your beloved laptop battery is not easy to use. How to choose a laptop battery so it? This problem should start with the basic battery from the laptop (hope that we adhere to the reading, although some very dogmatic.)

1) There are several laptop battery

Batteries used in notebook computers currently are three major types: 1. Nickel-cadmium batteries, 2. Ni-MH battery, 3. Lithium battery; they are generally expressed as: Nickel cadmium NI-CD, Ni-MH NI-MH, Lithium-Ion battery LI.

2) the composition of lithium batteries used

Laptop battery by a shell, composed of circuit boards and batteries, are lithium-ion batteries. Generally they say the batteries means the number of batteries within the battery, mAh refers to the laptop battery capacity. Mainly by the protection circuit board (or the secondary protection circuit), and indicating circuit capacity of two parts, on the laptop laptop batteryAcer AC Adaptersbattery charge and discharge and safety management.

3) Laptop battery life determinants

Laptop battery standby time determined mainly by the mAh value. In general, the more the batteries, mAh larger the longer standby time. Laptop battery life is primarily measured by the charge and discharge times, the quality of qualified products are generally 500-600 times. Therefore, the effective use of laptop battery within a period of 2 years, after which the battery will be aging, standby time of sharp decline in the mobility of notebook computers.

4) Key: laptop purchase, how to see the battery parameters

Buy notebook, consumers tend to see is the parameter list and quotation. Among them, the parameters on the laptop battery only one or two. That is, is not lithium batteries and a few core. Tell you that the market is now the most common is the 6-cell ion battery. Normal life, in high-performance mode, up to 2 hours (except for those outside of BT laptop).

Understanding of the common, is that how we look at the battery parameters. In a notebook battery can often be seen 4400mAh, 2200mAh nominal value such as batteries, and I said just now is to determine the endurance mAh key. I am sure there will be a lot of friends that the bigger the better mAh. But in fact not the case, the real master, a unit of battery capacity should be considered "Wh", its Chinese name "Wh." Of course, "Wh" and the "mAh" is a close relationship with the following formula: Wh ÷ V × 1000 = mAh should be noted that hp AC Adapters toshiba AC Adaptersmeasurement of electrical power consumption of the unit itself should be a power, that is, "Watt."

Keyboard and mouse clean.

Step 1, the keyboard upside down, slap the keyboard, the keyboard card keys will cause the debris to shoot the keyboard.
Step 2, use a mild detergent or a computer keyboard cleaning agents remove difficult to remove stains, scrub with a damp cloth and dry the keyboard.
Step 3 Clean the keyboard with a cotton swab inside the gap dirt.

Similarly, use the mouse after a long time, there will not listen to the command of the situation. Then dust on the need to be handled. In general, the mechanical mouse just need to clean up the "body" in the rolling ball and roll axis can be.
Step 1 Position the mouse at the end of the screw down, open the mouse.
Step 2 Use the mouse to scroll cleaners remove dirt ball and roll axis, and then the mouse can be installed.
The optical mouse to use more of seal design, so dust and dirt will not enter the house. Usually use the mouse, it is best to use the mouse pad, this will prevent dust and dirt into the mouse.
3. Chassis shell clean. Since the chassis is usually placed below the computer desk, usually not too much attention to sanitation, the enclosure is easily attached to the chassis of dust and dirt. We can dust with a dry cloth first removed, then dip a cloth dampened with water cleaning agent of some stubborn stains wipe, and then brush gently brush the surface of the chassis rear of the dust can be a variety of interfaces.
Four of inner cleansing

After completion of cleaning external equipment, the most important host internal cleansing began. Since the chassis is not sealed, so after a period of time will accumulate a lot of dust inside the chassis, so that the operation of computer hardware is very bad, very easily lead to excessive dust computer failure, or even the serious consequences caused by burning of the hardware, so the internal host The dust is very important and need to regularly, usually once a month is appropriate dust. More work needs to complete a regular basis, usually a simple way when cleaning the cleaning of a computer case.
1. Disassembly.
Note: The demolition of the former, we must shut down, and then release the body to wear anti-static gloves, static, or only after the following operation.
Step 1 First, unplug all the peripherals connected the back of the chassis, the chassis with a screwdriver under the back of a few screws, remove the chassis cover.

Step 2 and then put the host lying, so the motherboard down the window with a screwdriver on the edge of strip screws fixed the card, and then with both hands clenched on the edge of the interface card, unplug the interface card straight up.

  1. Hardware: the computer, the screen (monitor) is the external communication of the eye, eye injury, it is also the culprit for children. Therefore, the first step to avoid harm, of course, have a good display.Toshiba Satellite 4000 Adapter toshiba protege 4010 Adapter General standard with current computer is SUPER-VGA15 "800 * 600 size main Basically, not very different, but, in essence, a penny, for a half, in the same size should be chosen on the low radiation, high-quality non-interlaced scanning, magnetic, and power and other considerations. Of course, the installation of protective goggles is another to enhance function, so, in the purchase rate and the radiation efficiency of light have to pay more attention, so just install a shading mirror, but more of a burden on the eye damage. eventually, to remind the reader, if the budget permits, large size and high resolution, of course, is a better choice.
