Is it possible to use a laptop without a battery?
Any rechargeable battery in a laptop breaks down over time. If you work with a laptop at home, you can turn it into a desktop computer. You can use this mode for a long time without damaging the device. The most important thing is to properly disconnect the battery, ensuring all storage conditions.

Laptop without battery: can it be used?
Today, laptops are equipped with lithium cells, which after 600-700 charging cycles greatly lose capacity (about 25%). With frequent use, they fail after a year. Also, lithium cells are very critical to overcharging and deep discharge. All this is correct, but why use a gadget without a battery?
Any gadget contains a power supply circuit from a battery or from an outlet, that is, there is a microcircuit on the board that controls the 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 contains the same board called the BMS controller.
If the batteries are in the laptop and require recharging, the controller allows access to them for charging. In this case, the board controls the current strength, temperature increase, and voltage. When the parameters go beyond the possible maximum, the BMS turns off the battery.This prevents excessive heating and equipment failure.
The same thing happens during battery-powered operation of the gadget, that is, during discharge. The microcircuit monitors the voltage and turns off the device when it drops to critical levels. This prevents complete discharge and for this there is absolutely no need to use the laptop without a battery. All described actions are performed in normal mode, namely with the battery installed.
Reference! In addition, the power controller in the laptop itself switches to power supply mode from the outlet when the adapter is plugged into the network. If you disconnect the adapter, the controller will switch the device to battery power. That is, the battery in devices is the power source. So, during a power outage, you can continue to use your mobile computer on battery power. This is the main argument against using a gadget without batteries.
How to turn on a laptop without a battery
If you use a laptop at home, you can take it out to save the battery. Moreover, it is prohibited to store lithium cells when completely discharged: the charge must be at the level of 50%. That is, recharging is necessary 2-3 times every month.
You can use the gadget without the battery after it fails. To do this you will need:
- Completely disconnect the laptop.
- Turn the device over and open the battery compartment.
- Remove the autonomous power supply from the case.
- Close the compartment, then connect the power supply and power the gadget from the mains. Now it can be turned on and used for its intended purpose.
Features of using a laptop without a battery
Disconnecting the battery may occur for storage and does not allow the battery to retain its charge for a long time. The capacity decreases over time, although lithium cells fail much more slowly.As a rule, in 2 years it decreases to 15% of capacity. This can be prevented by regularly performing full charging and discharging. In this case, the battery will last longer.
Working with a device without a battery does not deprive you of any capabilities: you can watch movies, play games, run the required programs. If you take care of purchasing an uninterruptible power supply, you can ensure stable operation of your laptop.
And a desktop PC means it will work if there is no light and W/F too, so what happens?))))))
The respected author missed one important point. A laptop, like a desktop PC, requires constant power to support the BIOS. If there is no battery in the compartment, then every time you turn it on from the network, the date and system time will fly off with all the ensuing consequences (for example, the browser will not work), which means that every time after loading the Laptop they will have to be installed again, and this is annoying.
BIOS has a separate battery
Why even take out a damaged battery? from the laptop? Even if there is a charge there for 2-3 minutes, then it allows you to close correctly (like a UPS, if there is none).
If the battery fails, simply disconnect the battery and turn on the laptop and ALL! No need to remove the laptop battery. Bye.
nothing falls off, it has been working for 3 years without a battery, the flight is normal
this is if you have an old laptop in which you can remove the battery, but for me to disassemble the entire laptop, the battery is built-in, so it’s still under warranty so you can get into it
4 years after the purchase, I sold the laptop... The battery, except for occasional recharging, was lying on the shelf.
I lost 15-20 minutes out of 4 hours. The buyer was thrilled.

While the computer was running, I pulled out the battery and understood why it was hanging - I changed it, no one talks about the battery as a BIP, as a protection for the results of painstaking work, which is also why you need a laptop...
The BIOS in both desktop computers and laptops is powered by a separate battery, so disconnecting the main battery does not reset its settings. Likewise, unplugging the desktop computer from the outlet does not reset these settings.
In an uninterruptible power supply, the same battery also costs money. Uninterruptible power supply is installed for the computer. And in the laptop the battery is the same uninterruptible power supply.
in some models, if the battery is zero, the BIOS cannot be flashed
I do not recommend using a laptop without a battery. The main thing is to observe the charging and discharging regime of the battery.There is no need to worry too much about overcharging; after reaching 100% charge, the corresponding controller will disconnect the battery from the charger and the laptop will continue to work, powered by the charger. But only the laptop owner himself can protect against deep discharge (below 10% charge) by connecting the power supply from the mains.
I have had the battery in my laptop constantly for about 8 years now. Of course, the battery capacity has decreased during this time and I have to connect the charger more often.
I recommend this laptop battery operating mode: 10/20, i.e. The laptop runs on its own battery for 10 days (when the battery is discharged to less than 20% of the capacity, connect the charger). Work for the next 20 days with the charger constantly connected. Of course, after finishing work, disconnect the charger from the laptop.
So, during a power outage, you can continue to use your mobile computer on battery power. If the power goes out, the W/F will also turn off, which means the laptop is useless hardware.
