Asus - laptop charger: how to choose

Buying a new laptop or netbook, the owners and do not suspect how many problems they will face in the future: overheating of the graphics adapter in the heat, slow operation of the processor, sticking keys, a damaged touchpad and dust inside the case. All these problems can be solved with a single trip to the service center. But even with their appearance for some time you can safely work on the laptop, reducing the load on the video card, connecting the ventilation and additional peripherals.

But it is worthwhile to be prepared and to the fact that one day the device will stop recharging and operating, which will lead to significant problems.

Why the laptop does not charge

The reasons for which the charge will not reach the laptop, a few:

• Defective pilot.
• A bloated laptop battery.
• Broken power supply.

The biggest problem is a damaged power supply, since the pilot can easily be replaced, and the battery can be pulled and operated only from the network. Find out if there is a problem with the laptop power supply, it's very simple: for example, almost any charging for Asus is equipped with a light bulb-indicator. If it ceased to burn, then the probability that the power unit burned down - almost 100%. But do not despair. Selecting a new laptop charger is easy.

However, before you start choosing, it's worth to find out what it's for.

What is responsible for the power supply unit

In addition to the fact that in various gadgets, including Asus, the laptop charger supplies power to the battery and guarantees stable operation, it:

• Works as a fuse against voltage surges.
• Converts 220 volts to a suitable laptop.

But that the charger has worked for more than one year, it is important to choose it correctly.

Main characteristics of the power unit

Sometimes it's hard to find a charger for your Asus laptop. The price of the original power supplies is usually high: from $ 40 and above. However, different brands of devices, including Asus, the charger for a laptop is characterized by several characteristics:

1. Output voltage. What is the same for MSI gt780dx, Dell 3151 and Asus k53s? The charger, or rather, its output voltage. This figure is the same as the voltage consumed by the laptop. The error can be from 3 to 5%. For example, the voltage that the charger provides for the Asus laptop is 19V.
2. Maximum power. For each model of the laptop, the maximum power consumption is given. The figure should not be less than the output voltage. For example, the Asus model. The laptop charger, consuming 70 W, will work perfectly with a 100 Watt or more power supply. If the maximum power is not indicated on the charger, it can be calculated. Multiplying the output voltage by the maximum permissible current (in amperes), the maximum power is obtained.
3. Plug. The most important aspect when choosing a power supply is the connector. Almost in all power supplies, the connector for the plug is the same: a hollow cylinder. The connector is characterized by internal and external diameter and polarity. It is important that the power plug sits tightly in the connector, otherwise the supplied voltage may change the polarity, which will adversely affect the operation of the laptop.

Universal or original power supply?

If the charger for the Asus notebook is out of order, the price for a new one can be very high. This applies to almost all models of laptops. Therefore, many owners wonder: why not purchase a universal charger? Pluss in favor of this decision is somewhat:

• Lower price;
• Availability in stores;
• wide choose.

Undoubtedly, it's easier to find a universal charger for the Asus laptop. The price will not be so "biting". But it is with the original power supply that the laptop will work better.

Durability

Popular models of computers - Dell, HP, Lenovo, Asus - the charger for the laptop is distinguished by several nuances. First, the manufacturers of power supplies give the time to work for a rollback. It is this characteristic that guarantees a long service life.

Such models of chargers are somewhat more expensive than universal ones, but the guarantee for a certain number of hours of operation is a sign of high quality. Information about the power supply unit can be found on the product packaging. Usually such chargers work at least 3-5 years.

Where can I buy?

When a laptop charger breaks down, many owners are wondering: where can I get a new power supply? For the brands HP, Lenovo, Dell, Acer and Asus, the laptop charger can be purchased in specialized stores. But often there is not always a necessary model of power supply available. Then you can contact the stores that sell peripherals.

However, the simplest option is to order a power supply in a specialized store. When buying universal models you need to carefully review the characteristics. By purchasing the original charger, simply place an order.

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

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