Cannot Connect Wifi On Laptop Hp Probook4530s

A charger, or AC adapter, is one of the first parts to replace in a laptop, even with careful use. The charger always works for wear, it is dropped, attacked, lost, in the event of a voltage drop, it first takes a blow on itself, protecting the laptop.

Network adapter. what is it and how to find the right replacement for it?

What is the adapter for a laptop for?

An external network adapter does not just supply current to the laptop, but converts the network voltage from 220V or 110V to the 18-24V required for your computer. Modern manufacturers produce adapters that work on the principle of pulse conversion, for the user this means the most efficient conversion with minimal loss. Simply put, save energy without losing power.

Important Charger Tasks

A laptop is much more vulnerable to power surges than, for example, a regular computer. Even a small difference can burn important cards so that the device cannot be restored.

Technically, installing the power supply directly into the chassis is not quite economical, therefore, the network adapter is also a power supply that protects the laptop from power surges. On average, depending on the model, the laptop charger can withstand a jump of 5-15% more than the usual operating voltage of the network.

Extend Network Adapter Life

To extend the life of the network adapter, you need to follow a number of simple rules:

  • Do not leave the power supply plugged in and not connected to the laptop;
  • first connect the charger to the laptop, and then to the outlet;
  • do not overheat. For example, do not cover the adapter during operation, do not keep close to the heater;
  • do not allow pets to bask on the power supply or play with neither;
  • use only indoors;
  • keep the device clean; in case of contamination, clean it with a dry cloth or cloth, after disconnecting it from the mains.

if you use a power supply designed for less power than the laptop you are using, then most likely the adapter will burn without recovery and it will be better if the adapter breaks, not the laptop

How to choose charging for a famous laptop

If your charger is out of order, in no case do not throw it away. The original power supply always indicates the parameters and service codes that make it easy to find a replacement. At a minimum, you need to photograph the characteristics and the plug to show in the service center what exactly you are looking for.

The replacement power supply can be original and non-original.

The original adapter is usually manufactured directly by the manufacturer of the laptop and fully complies with all the necessary technical specifications. The original power supply is of high quality and reliability, and, accordingly, a higher price.

Non-original power supplies are available for a particular brand of laptop, but most often come across universal ones equipped with a set of plugs and a voltage switch. The quality of the device can only be guaranteed by the company that produces it, and, unfortunately, cheap and low-quality models are often found among non-original adapters.

When purchasing a universal charger, the parameters and plug suitable for your laptop will need to be installed independently. The power of the universal charger is not set manually, therefore, the power supply indicated on the power supply must be greater than or equal to what is needed for your laptop. Find out in advance whether the set of plugs is suitable for your model, be prepared for possible incompatibilities. Some brands of laptops, for example, do not work with non-original and universal devices at all.

The parameters that determine the compliance of the laptop charger:

  1. plug type. Most often, each laptop manufacturer produces its own special connector, because chargers and laptops of different brands are not compatible;
  2. voltage. It is measured in volts (V) and most often has a range from 15V to 24;
  3. maximum current, measured in amperes (A), may be greater than the nominal, but in no way should be less
  4. power, measured in watts (W), may be higher than what a laptop needs, but not lower. If power is not specified in the adapter specifications, it is calculated by simply multiplying the indicated current strength and voltage.

Separately, it is worth mentioning the input voltage, since all countries have their own industrial network standards, the range of most chargers varies from 100V to 240V. This allows you to use the device with our 220V, and, for example, with the American 110V, but in rare cases, if the laptop is purchased abroad, the maximum input voltage may not meet our standards.

Safety in use

The network adapter is quite simple by modern standards, but still requires certain security measures when using:

  1. Do not try to open the power supply case, even if it needs to be restored. a proven master should do this;
  2. disconnect the adapter from the network during thunderstorms;
  3. Before connecting the adapter, check all the specifications with your laptop. Mismatch of the parameters can permanently disable either the power supply or the laptop;

Laptop Network Adapter Driver. Power Management

Having purchased a new charger, we recommend downloading drivers to the Windows 7 network adapter for a laptop in order to optimize the operation of the new device. These drivers bring great benefits in the balance of power consumption and performance, are responsible for the correct indication of the laptop, ensure stable operation of the device. In addition, the adapter driver, while maintaining the power balance of the battery, increases its service life by several times.

Possible problems with the adapter

If the laptop does not see the network adapter, you need to determine one of the possible reasons. First check for possible mechanical causes:

  1. lack of voltage in the network;
  2. check if there is light at home, if there is, then most likely the problem is in the outlet;
  3. adapter breakdown. If the laptop is charging from another charger, most likely your will need repair or replacement. Do not try to repair the adapter yourself; consult a specialist;

If the charger and laptop are fine, but there is still no charge, the cause is most likely a software problem:

  • BIOS failure. A sloppy attempt to solve this problem can greatly damage the entire operation of the laptop. The cause of such a breakdown may be a powerful virus attack, or an unsuccessful BIOS update. Do not take the risk once again and give the laptop in for repair;
  • disturbances in the driver. This is a fairly rare problem, but such an option cannot be ruled out. Check the operation of the drivers with a special program and reinstall the incorrect one.

The AC adapter is a simple and interchangeable part, but requires careful handling. The issue of buying a new charger must be approached responsibly, checking all the factors and characteristics, since not only the money spent, but also the health of your laptop depends on it.
