A laptop is a mobile device, that is, an analogue of a stationary computer that is designed for portable use. But, like many portable devices, it requires periodic charging. If the laptop does not work from the network or does not save battery power, then this is a serious problem.
Laptop battery
If the laptop is powered from the network, but does not charge, then it is worth doing some manipulations. However, they cannot be considered unequivocally safe, so you will have to do this at your own peril and risk.
First, take the battery out of the laptop and connect the power cable to it. Then you should turn on the device and wait for the operating system to start. After that, you can insert the battery into the laptop.
Laptop power supply
The laptop does not work from the network for another reason - a malfunction of the power supply, which can often fail. With power fluctuations, its performance is poor. The fact is that the task of the transistor, which is located inside the power supply unit, is to convert the alternating 220 volts into constant 12 volts. However, it is difficult to cope with this if the voltage constantly jumps. In connection with this situation, the power supply may simply burn out.
The solution to this problem is very simple - replacing an inoperative power supply with a similar new one. Just when buying, you need to know the model of the laptop and its connector, then you can avoid the return.
Power cord
Another reason why the laptop does not work from the network is the unusable power supply cord.
The first case involves the connection of the power supply to the cord that is included in the outlet, as it is subject to constant bending and friction. In the event that the part connecting to the power supply has been damaged, it can be repaired independently. To do this, you will need wire cutters and electrical tape. The damaged area must be cut, and the wires insulated. Then the surviving parts are interconnected.
Of course, this method will forever spoil the appearance of the device, but give it time to work a little more to wait until it is completely replaced with a new one.
In the second case, the power cable breaks down at the place where the plug is connected to the charging connector of the laptop. This happens due to inaccurate transportation or constant movement of the cable in that place.
The solution is completely similar to the first case, but it is better to replace the cable with a new one.
Power supply cable connector
If the laptop does not work from the network, then the reason may be hidden in the plug itself for the charging cable of the device.
For some time, when the laptop is constantly transported without proper approach, the power plug may also be damaged. Checking the charging socket for serviceability is simple - if the laptop displays the charge level only when the plug in the socket is in a certain position, then the problem is precisely in the connector.
If you have enough experience in assembling / disassembling laptops, then you can try to replace the connector yourself. In another case, in order not to damage the motherboard, it is worth returning the equipment to a repair service.
Motherboard problems
If all of the above options did not help determine why the laptop is not working on the network, then the problem is most likely in the motherboard. True, an ordinary user will not be able to accurately determine the area of failure, since it can be transistors, capacitors, and much more.
The most optimal solution to this case is to contact the service center, where an experienced specialist will diagnose and issue a verdict.
Can a laptop run on AC without battery
There are cases of damage to the laptop battery, which leads to its complete elimination, so the question arises as to whether to use a laptop without a battery.
Of course, a laptop is subject to prolonged use in the absence of a battery, only if several conditions are observed:
- Firstly, the power supply used must be proprietary, that is, the one that came with the laptop.
- Secondly, the supplied voltage should not jump, for this it is better to purchase a special filter.
- Thirdly, in order to be completely sure that the voltage will not change dramatically, it is necessary to install uninterrupted equipment that provides a stable voltage supply.
These methods will undoubtedly help to use a laptop in the future, but then it will lose its mobile superiority over a desktop computer. Therefore, it is easy to immediately understand whether a laptop can work from the network without a battery.
Operation tips
To avoid all previous situations, it is worth taking the advice of specialists. And to begin with, it should be noted that a constant connection to the network leads to an accelerated breakdown of the laptop battery, so it is recommended to disconnect it immediately when the battery is fully charged.
Since the batteries are lithium-ion, they constantly need to both discharge and charge, so working outside the network is required.
