Asus - laptop charger: how to choose

By purchasing new laptop or a netbook, the owners have no idea how many problems they will have to face in the future: overheating graphics adapter during the heat, slow work processor, damaged touchpad and dust inside the case. All these problems can be solved with one trip to service center... But even if they appear, you can safely work on a laptop for some time, reducing the load on the video card, connecting ventilation and additional peripherals.

But you should be prepared for the fact that one day the device will stop charging and working, which will lead to significant problems.

Why the laptop won't charge

There are several reasons why the charge will not reach the laptop:

• Bad pilot.
• Bloated
• Broken power supply.

The most big problem is a damaged power supply unit, since the pilot can be easily replaced, and the battery can be removed and operated only from the mains. Finding out if there is a problem with the laptop's power supply is very simple: for example, almost any charger for Asus is equipped with an indicator light. If it stops burning, then the probability that the power supply has burned out is almost 100%. But you shouldn't despair. Choose new Charger for a laptop is very simple.

However, before proceeding with the choice, it is worth finding out what it is for.

What is the power supply responsible for?

In addition to being in various gadgets, including Asus, a laptop charger supplies power to the battery and guarantees stable work, he:

• Works as a surge protector.
• Converts 220V voltage to suitable for laptop.

But in order for the charger to work for more than one year, it is important to choose the right one.

Main characteristics of the power supply

It is sometimes difficult to find a charger for Asus laptop... The price of original power supplies is usually high: from $ 40 and up. However, the different brands devices, including Asus, the laptop charger has several characteristics:

1. Output voltage. What is the same for MSI gt780dx, Dell 3151 and Charger, or rather, its output voltage. This figure coincides with the voltage that the laptop consumes. The error can be from 3 to 5%. For example, the voltage supplied by the Asus laptop charger is 19V.
2. Maximum power. The maximum power consumption is given for each laptop model. The figure should not be less than the output voltage. For example, model Asus... A laptop charger that draws 70W will work fine with a 100W or more PSU. If the charger does not indicate maximum power, it can be calculated. By multiplying output voltage to the maximum permissible current(in amperes), the maximum power is obtained.
3. Plug. Most important aspect when choosing a power supply - connector. In almost all blocks, the plug is the same: a hollow cylinder. The connector is characterized by an inner and outer diameter and polarity. It is important that the power plug fits snugly into the connector, otherwise the supplied voltage may reverse polarity, which will adversely affect the operation of the laptop.

Universal or original power supply?

If your Asus laptop charger is out of order, the price of a new one can be very high. This applies to almost all laptop models. Therefore, many owners are wondering: why not get a universal charger? There are several advantages in favor of this solution:

• lower price;
• availability in stores;
• wide choose.

Undoubtedly easier to find for an Asus laptop. The price will not be so "biting". But it is with the original power supply that the laptop will perform better.

Durability

Have popular models computers - Dell, HP, Lenovo, Asus - the laptop charger has several nuances. Firstly, the manufacturers of power supplies issue the operating time for rollback. It is this characteristic that guarantees a long service life.

Such models of chargers are somewhat more expensive than universal chargers, but the warranty for a certain amount of hours of work is a sign High Quality... Information about the power supply can be found on the product packaging. Typically, these chargers last at least 3-5 years.

Where can I buy?

When a laptop charger fails, many owners wonder: where to buy new block nutrition? For HP, Lenovo, Dell, Acer and Asus charger a laptop device can be purchased at specialized stores. But often there is not always available required model power supply. Then you can go to shops selling peripherals.

However, the easiest option is to order a power supply from a specialized store. At the time of buying universal models you need to carefully read the characteristics. By purchasing an original charger, simply place an order.

You can also use the services of well-known online stores. On such sites you can always find suitable model charger, and also choose the product that will cost less. The advantage of such a purchase is that you can purchase a power supply unit for a promotion.

Breakage of any component of a laptop is always a problem that requires maximum quick solution... But the main thing is not to choose peripheral devices, including the power supply, from unverified and unknown manufacturers. Then the laptop will serve for a long time and without unnecessary failures.

How to properly charge a netbook battery?

The master's answer:

The first check is carried out when buying a mobile computer. If you do not purchase a netbook from an online store, then this opportunity is quite available to you. With your netbook plugged in, turn it on. Allow its battery to charge fully. Now we look at the indicator readings in the system tray.

A rechargeable battery is considered to be of poor quality if its charge level does not rise above 98%. It is better to give up such a mobile computer right away. In general, you need to learn how to charge a netbook battery correctly.

In the off mode, connect the netbook to the network alternating current... You need to charge it until the charge level reaches maximum value... Observe the indications of the indicator on the case mobile device if such exists. It shows in one way or another that the battery is charged (sometimes it just changes color). After full charge battery, disconnect the netbook from the network.

We turn on the netbook and leave it on until its battery is completely discharged. This technique must be repeated several times. But to maximize the life of your battery, you don't need to use it when you can connect your computer to an electrical outlet.

It is not recommended to store a fully discharged battery separately from the computer. It is better to recharge it by 40-60% before extracting. Even if your mobile computer most time is used at home, at least once every two to three months, try to connect to it battery to help prevent damage to the removable battery.

And if you take care of purchasing a spare battery in advance, then in the future you will not have to look for a similar model, and your netbook will be able to do without the need for recharging for a long time.
