Notebook power adapter selection method

1, choose a good brand:

     The principle is to choose the same type of brand, if not, it can only find other brands. Now many of the laptop online power adapter sold are cut corners of substandard products, normal use should be no problem, in the event of an accident will burn your laptop, save dozens of pieces but burn thousands of notebook worth the candle. (Cut corners, the common practice of chaos standard power, such as the actual only 19V3.42A, but the standard 19V4.74A, this will lead to charging is very slow, or even damage the battery and laptop, there are some protection removed, this more horrible, there Accidentally burn the laptop.)

    I suggest you ample funds, you can buy a professional brand notebook power adapter (that is, only the professional laptop charger brand, not what the power to do that kind of professional-brand products only Will cause damage to the battery and laptop, but also advanced protection circuit.) Such as outeccbattery and so on.

2, distinguish clearly use:

     Home and office notebook power adapter used to sell a home to buy (AC), the car with a laptop power adapter, buy a car, you want to use the aircraft on the basis of the car On the plane with a plane on it. At home, in the car, in the airplane, all want to take care of, buy a combo, or triple. However, if you do not want to have multiple weights in your computer bag, you can put one at home, one in the car and one in your office so that you do not have to bring it in, plug it in and plug it in, .

3, distinguish between voltage, current and interface

     Look at the original laptop which brand, the original charger behind the label is written on the number of V, how many A (generally written in OUTPUT behind), the charger connector is round or square, or porous, Do my heart probably a few, will not buy the wrong, or even fooled.

     Adapter output voltage and laptops are the best voltage required for the same, if different, then as close as possible laptop voltage, control within ± 5% error, this is because the laptop inside the regulator circuit generally have margin design , When the input voltage changes within a certain range, can work normally and stability; beyond this range, the voltage is too low, the computer may not work even unstable lighting machine; voltage is too high, the computer may burn the regulator circuit. Such as an Acer notebook, which requires 15V, 3.36A input, but with the IBM 16V, 3.36A adapter can be used with it properly.

Every day use Tips to extend your Microsoft Surface Keyboard G3HTA024H laptop’s battery life
1.Keep the Microsoft Surface Keyboard G3HTA024H battery contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
2.Do not expose the Li-ion G3HTA024H battery to extreme temperatures. Do not leave your battery outside in the cold or in your car in the summer. Cold batteries can’t create very much power and hot batteries will discharge very quickly.
3..Avoid allowing your device to discharge completely. Constantly recharging a lithium-ion battery does not shorten the battery life more than normal usage would. Avoid letting it sit on empty for too long; instead, keep it charged-up if you can.
4.Keep vents clear – don’t put your Microsoft Surface Keyboard batteries on a fluffy pillow or a cushioned service that will cover vents and trap heat.
5.Chargeable batteries will wear down quickly, when they are only charged for a short period of time. When the laptop is not in use, such as at bedtime, plug it into an outlet and leave it to charge until the battery power is full.
6.Don’t pack your laptop away in a backpack or other enclosed space when the Microsoft Surface Keyboard G3HTA024H 7.5V battery is still warm, trapping the heat. A battery that is frequently hot to the touch will lose life a lot faster than a battery that isn’t constantly being stressed. Worst of all: if your laptop crashes or refuses to shut off properly, the battery can get extremely hot when packed away in your bag.
7.Defrag regularly – The faster your hard drive does its work – less demand you are going to put on the hard drive and your Microsoft Surface Keyboard Series battery. Make your hard drive as efficient as possible by defragging it regularly.
Choose a laptop battery to choose good quality, because the battery is too important for the laptop, and we can do for you is to provide preferential prices, reliable quality and excellent service.

Make Your Battery Last Longer

Mobile phones come with lithium batteries which require some maintenance as long as they are used. Once you know how, you can optimize your phone battery life fairly easily.

1.Turn the phone off. Only do this if it's going to be for several hours; turning a phone on/off actually uses a massive amount of power itself. This will probably be the most effective and simple way of conserving your battery’s power. Why? This will help conserve energy and also charge your phone. If you don't plan on answering the phone while you're sleeping or after business hours, just turn it off.

2.Stop searching for a signal. When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so. This is easily understood if you have ever forgotten to turn off your phone on a flight. The best way to ensure longer battery life is to make sure you have a great signal where you use your phone. If you don't have a perfect signal, get a cell phone repeater which will amplify the signal to provide near perfect reception anywhere or simply turn on flight mode.

3.Do not follow the method of full charge and full discharge. Avoid letting your cell phone's battery run all the way down. Lithium-based batteries are designed to be charged early and often, and letting them get too low can damage the battery. With lithium-based batteries, doing shallow discharges and frequent charging prolongs battery life.

4. Switch the vibrate function off on your phone. Use just the ring tone. The vibrate function uses additional battery power. Keep the ring tone volume as low as possible.

5.Turn off your phone's back light. The back light is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to use the back light, many phones will let you set the amount of time to leave the back light on. Shorten that amount of time. Usually, one or two seconds will be sufficient. Some phones have an ambient light sensor, which can turn off the back light in bright conditions and enable it in darker ones.

6.Avoid using unnecessary features. If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.

7.Keep calls short. This is obvious, but how many times have you heard someone on their mobile phone say, "I think my battery’s dying," and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone, but if you really need to conserve the battery, limit your talk time.

8.Turn off Bluetooth. It will drain your phone battery very quickly. Only turn Bluetooth on when needed.

9.Same goes for WIFI, GPS, and infrared capabilities, if your phone has these features built in. Keep them off except when you need them.
