Probably, many people were faced with a situation where the laptop refused to work without a 220 V network battery. There may be several reasons for this. Let's look at this issue.

Should the laptop work without a mains battery
Sometimes the question arises, is it possible to work a laptop without a battery, and should it even work like that. In general, most of the models can easily and simply connect to the network with the battery removed. To do this, a controller is provided on the motherboard, which automatically switches the power to the battery if it is not charged, or directly to the laptop, if the batteries are charged to 100% or removed.
There are also some models that simply do not provide for work without a battery. Usually these are old models that are simply not designed for such actions. They use the battery as part of the circuit. That is, first the idea is powered by the battery, and then into the laptop and if the battery is removed, the circuit will be open.
Separately, it should be noted that using a laptop without a battery makes sense only if the battery fails. In order to save battery life, it is not worth extracting it. The fact is that the controller on the motherboard independently copes with disconnecting the battery, and working from an external power source does not affect the battery life.
If you work without a battery, it is better to use a UPS in case of a power surge or a sudden power outage.
Causes and Solutions
Sometimes it happens that you need to connect the laptop to the network directly, without a battery, but this does not work. No power is supplied. There may be several reasons for such inappropriate behavior.
Network operation not provided
First, make sure that the laptop allows such a connection. If you have a modern gadget, even Chinese-made, no problems should arise. But, five years ago, many laptops did not support work from the network directly. Necessarily required battery. Now this is found only in the cheapest models or replicas.
But, nevertheless, the first thing to check is whether the laptop can work without a battery.
Lack of electricity in a network
Another commonplace situation - the socket is simply disconnected. It really happens. In this case, the laptop will not work naturally. Just in case, check if there is current in the network.
- Connect any known-good device to the power outlet. If it works, then there is current.
- If there is no voltage, check the automatic fuses. Sometimes they are made on separate devices, perhaps this is your case.
If the fuse turns on, but there is no current, it is worth calling a specialist, but for now, use a different outlet.
Worn wire
Quite often, the reason is the power supply wire. As a result of operation, as well as regular transportation, the cord may break. To identify a similar problem is quite simple, it is enough to move the wire, if the reason is in it, under certain conditions there will be power. You can also check the wire with a multimeter. Usually there is a break in the following places.
- Bummer at the base. Directly near the unit, the cord is constantly subjected to various loads. As a result, it breaks quickly. To avoid this, it is necessary to carefully and accurately arrange the cord during use and transportation. If a breakdown has already occurred, you can try to restore the integrity of the product.If the breakage is not near the unit itself, cut off the damaged section of the wire, and wind the remaining ones. In the event of a break directly near the unit, you will have to disassemble it and solder the wire to the contacts.
- At the plug. Usually occurs after transportation with connected charging. Due to improper location, the conductor breaks. This is solved either by replacing the damaged portion of the wire, or by completely replacing the cord.
The power supply flew
A fairly common problem is that the power supply simply does not work. It can burn out quietly, or noticeably, with smoke. In any case, the malfunction will not allow the device to work further. There is only one way to solve the problem - buying a new block.
When choosing a new unit, pay attention to the connector and power. They should fit your laptop.
Broken connector on the memory or laptop
Another common problem. If the gadget was used inaccurately, transported with the cord connected, lifted by the wire, there is a chance of damage to the socket. The antennae coming into contact with the plug may bend, or the contacts may break off directly in the laptop itself. There may be several reasons.
You can solve the problem only by replacing the socket. To do this, you will have to completely disassemble the device. If you are not confident in your skills, it is better to contact a service center for repair. Any error during operation can lead to other breakdowns.
The controller on the motherboard broke
As already mentioned, the corresponding controller is responsible for operating in the "without battery" mode. If the laptop does not turn on without a battery, the reason is probably the motherboard. The microcircuit can start to work if you change the corresponding capacitors and transistors.
It is very difficult to identify this cause yourself. Eliminate it at home is also not possible. It is best to turn to specialists who will restore the controller.
Conclusion
Most modern laptops work without battery problems. But sometimes difficulties arise. They may be due to a malfunction of the power supply, wires or components of the laptop itself. Diagnosis and elimination of some of the causes can be done independently. If the problem is in the connector or the motherboard, you will have to contact the service for help.
