Buying a new laptop or netbook, the owners have no idea how many problems they will face in the future: overheating of the graphics adapter in the heat, slow processor operation, sticky 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, you can still work on a laptop for a while, reducing the load on the video card, connecting ventilation and additional peripheral devices.
But it’s worth being prepared for the fact that one day the device will stop charging and working, which will lead to significant problems.
Why the laptop does not charge
There are several reasons why the charge will not reach the laptop:
- Faulty pilot.
- Swollen laptop battery.
- Broken power supply.
The biggest problem is a damaged power supply, as the pilot can be easily replaced, and the battery can be removed and only work from the mains. To find out if there is a problem with the laptop power supply is very simple: for example, almost any charge for Asus is equipped with an indicator light. If it stops burning, then the probability that the power supply burned out is almost 100%. But do not despair. Choosing a new laptop charger is very simple.
However, before proceeding with the selection, it is worth knowing why it is needed.
What is the power supply responsible for?
In addition to the fact that in various gadgets, including Asus, the laptop charger supplies power to the battery and guarantees stable operation, it:
- It works as a surge protector.
- Converts 220 V voltage to a laptop.
But for the charger to work for more than one year, it is important to choose it correctly.
The main characteristics of the power supply
It is sometimes difficult to find a charger for your Asus laptop. The price of original power supplies is usually high: from $ 40 and up. However, for different brands of devices, including Asus, the laptop charger has several characteristics:
- Output voltage. What is the same with MSI gt780dx, Dell 3151 and Asus k53s? Charger, or rather, its output voltage. This indicator matches the voltage that the laptop consumes. The error can be from 3 to 5%. For example, the voltage that the charger for an Asus laptop gives out is 19V.
- Maximum power. For each laptop model, maximum power consumption is issued. The figure should not be less than the output voltage. For example, the Asus model. A laptop charger that consumes 70 watts will work fine with a 100 W 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 allowable current (in amperes), the maximum power is obtained.
- Plug The most important aspect when choosing a power supply is the connector. In almost all power supplies, the connector for 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 sits tightly in the connector, otherwise the supplied voltage can reverse the polarity, which will adversely affect the operation of the laptop.
Universal or original power supply?
If the charger for your Asus laptop fails, the price of a new one can be very high. This applies to almost all laptop models. Therefore, many owners are wondering: why not buy a universal charger? There are several advantages in favor of this solution:
- lower price;
- availability in stores;
- wide choose.
Sure, it's easier to find a universal charger for your Asus laptop. The price will not be so “biting”. But it is with the original power supply that the laptop will work better.
Durability
In popular computer models - Dell, HP, Lenovo, Asus - the laptop charger has several nuances. Firstly, manufacturers of power supplies give the time between rollbacks. It is this characteristic that guarantees a long service life.
Such models of chargers are somewhat more expensive than universal ones, but a guarantee for a certain number of hours of operation is a sign of high quality. Information about the power supply can be found on the product packaging. Typically, such chargers last at least 3-5 years.
Where could I buy?
When a laptop charger fails, many owners wonder: where to buy a new power supply? For HP, Lenovo, Dell, Acer, and Asus brands, you can buy a laptop charger in specialized stores. But often there is not always the necessary power supply model available. Then you can go to stores selling peripheral devices.
However, the easiest option is to order a power supply in a specialized store. When buying universal models, you need to carefully familiarize yourself with the characteristics. Buying an original charger, just place an order.
You can also use the services of well-known online stores. On such sites you can always find a suitable charger model, as well as choose the product that will cost less. The advantage of such a purchase is that you can purchase a power supply unit for the stock.
Damage to 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 the power supply, from unverified and unknown manufacturers. Then the laptop will serve for a long time and without unnecessary failures.
