Any rechargeable battery in the laptop after a time fails. If you work with a laptop at home, you can make a desktop computer out of it. You can use this mode for a long time without damage to the device. The most important thing is to properly disconnect the battery, ensuring all storage conditions.
Laptop without battery: can I use
Today, lithium cells are installed in laptops, which after 600-700 charge cycles lose a lot of capacity (about 25%). With frequent operation, they fail in a year. Also, lithium cells are very critical for recharging and deep discharge. All this is correct, but why use a gadget without a battery?
In any gadget there is a power supply circuit from a battery or from a power outlet, that is, there is a chip on the board that controls power supply.
If you connect the power supply to the device port and insert it into 220 volts, the microcircuit switches the power supply from the outlet. In this case, if required, the lithium cells are recharged. The battery is the same board, which is called the BMS controller.
If the batteries are in a laptop and require recharging, the controller allows access to them for charging. At the same time, the board makes control of the current, temperature increase, voltage. When the parameters go beyond the maximum possible, BMS disables the battery. This prevents excessive heat and equipment failure.
The same happens during battery life of the gadget from the batteries, that is, during discharging. The microcircuit monitors the voltage and turns off the device during a decrease to critical parameters. This does not allow full discharge and for this you absolutely do not need to use a laptop without a battery. All described actions are performed in the normal mode, namely with the battery installed.
Reference! In addition, the power controller in the laptop itself switches to the power supply mode from the outlet when the adapter is turned on. If you disconnect the adapter, the controller will switch the device to battery power. That is, the battery in the device is the power source. So, during a power outage, you can continue to use the mobile computer from the battery. This is the main argument against operating a gadget without batteries.
How to turn on the laptop without battery
If you use a laptop at home, then you can get it for the safety of the battery. Moreover, it is prohibited to store lithium cells at full discharge: the charge must be at the level of 50%. That is, 2-3 times each month, recharging is required.
You can use the gadget without a battery after it fails. This will require:
- Completely disconnect the laptop.
- Turn the device over and open the battery compartment.
- Remove the self-contained power supply from the enclosure.
- Close the compartment, then connect the power supply and power the gadget from the mains. Now it can be turned on and used as intended.
Features of using a laptop without battery
Disconnecting the battery may occur for storage does not allow a long charge. Capacity decreases over time, even though lithium cells fail much more slowly. As a rule, in 2 years it is reduced to 15% of the capacity. This can be avoided if you regularly perform a full charge and discharge. In this case, the battery will last longer.
Working with a device without a battery does not deprive of any possibilities: you can watch movies, play games, run the required programs. If you take care of acquiring an uninterrupted power supply, then the laptop can ensure stable operation.
