Can an ordinary laptop work without a built-in battery? The question excites the minds of many inexperienced users. In this article, we will try to dispel all myths regarding the autonomy of the portable assistant and tell someone why and, most importantly, when it is not needed at all.
When buying a laptop, mobility is a determining factor. Equally important is the ability to work away from AC sources. For the autonomy of the gadget meets the built-in battery. It depends on its capacity how long the device will last without additional recharging.
Laptop batteries
Is it possible to use a laptop without a battery when powered from the mains?
The internal structure of the laptop is not much different from the structure of a stationary PC. It contains all the elements of the "big brother", only in a reduced form - with lower operating frequencies, power consumption and heat dissipation.
Unlike a processor or hard drive, a battery is not a vital part. Whether the laptop will work with a battery is a matter of autonomy, but not the health of the device.
Lenovo Y50-70 Model (Internal Device)
For example, we will analyze the internal structure of the Lenovo y50-70 laptop (Figure 1). In this model, the battery is non-removable and is located inside the case.
Charging and powering the device offline takes place via a cable connected to the motherboard. Mains power is supplied directly through the motherboard (top right). Therefore, the lack of battery does not affect the operation of the gadget. This is clearly visible in the image.
Battery Removal Instructions:
- find a diagram of your laptop model;
- make sure that the device has a removable battery (otherwise you will need to remove the bottom cover, which threatens with a loss of warranty);
- disconnect the laptop from the network;
- put the latches in the "open" state;
- with a slight movement (without using force) pull out the battery.
Why use a laptop without a battery
Using a laptop without a battery
There are two likely scenarios when the battery is better, and sometimes necessary, to remove. In the first case, when the laptop is at home and is a replacement for a stationary computer. In modern models (already 10 years old), the built-in controller prevents overcharging of the battery. But, over time, the marginal Battery capacity falls, which reduces battery life. In this case, it can be removed, and connected only if necessary.
This approach has both strengths and weaknesses. Indeed, the battery will last longer. If extending his life is a priority - this is one of the possible solutions. Removing the battery, on the other hand, makes the laptop defenseless before turning off the power. If the light goes out, the device will instantly turn off, and all data that was processed at that moment will be lost. For those who work with texts, models or draws - this is the risk of losing important information, which is not always justified. You should think several times before making an appropriate decision.
Removing the built-in battery from a laptop
If you decide to store the battery outside the laptop, you should make sure that it is fully charged. Most models are equipped with lithium batteries, which are equally sensitive to both deep discharge and overcharge.But if there is protection from overcharging in the form of an integrated controller, then in order to avoid too low a charge level, periodic maintenance is necessary. For long-term storage, it should be done once every six months. It is necessary to carry out 1 full charge-discharge cycle, recharge and send for further storage.
The second option - when removing the battery due to the need to replace it or a threat to the device. Most often this happens due to mechanical damage or water entering the body. Then use a laptop with a faulty power source is strictly prohibited! Otherwise, there is a possibility of a short circuit or fire, which can "kill" the device.
How to turn on the laptop without battery
Turn on the laptop
We clarify for those who doubt whether it is safe to use a laptop without a battery. The presence or absence of this detail will not affect its work and will not prevent it from being turned on. The only thing to remember is that the laptop must always be plugged in, otherwise it just won’t “start up”. The analogy with a stationary PC, which is connected to the network through an uninterruptible power supply, is most appropriate here.
Otherwise, there are no special restrictions or precautions. If you decide not to remove the battery, but want to keep it working as long as possible, we recommend using special programs. For example, the utility "Energy Manager" for laptops brand Lenovo. Each manufacturer has similar programs.
