Can I use Laptop while Charging?

Yes, you can use a laptop while charging.

When you are connected to the A/C adapter, the battery does not power your laptop and only excess power is sent to the battery.

In addition, when you are plugged in, the battery does not charge continuously and once the charge level drops below 95%, it topped off.

Since the battery is not used when plugged in, it can take several hours to lose 5% without an active drain.

Cautions to use a Laptop while charging:

  • When a laptop battery is fully charged, its capacity decreases to a maximum resulting in a 20% reduction in capacity each year.
  • If you use a laptop while charging, you should remove the battery when it is 50% charged and keep it in a cool place (heat also destroys the health of the battery).
  • Some manufacturers like Lenovo offer ‘Battery Health Mode’ which accomplishes the same task by lowering the charging threshold by up to 50%.
  • While gaming, make sure your laptop is adequately checked so that the battery temperature does not rise to dangerous levels.

Factors affecting laptops while charging:

1. Types of Batteries:

Lithium-ion batteries are included in the majority of laptops.

Since these batteries don’t have a memory effect, discharging and recharging cells won’t affect their life.

Charging will stop when your battery reaches full capacity; keeping your laptop connected will not harm it.

2. Cycles and Calibration:

It is advisable to avoid discharging the lithium-ion battery completely before recharging it to full capacity, a technique known as the “deep cycle”, which is only useful for nickel-cadmium and nickel-metal hydride batteries.

To recalibrate the battery, ensure a deep cycle once or twice a month.

This permits the battery monitoring mechanics to accurately specify the battery life.

3. Heat:

Always using a laptop while charging is not harmful to health, too much heat can destroy the battery over time.

When you use processor-centric apps like games or multiple programs open at the same time, you generate more heat.

If your computer became hot after plugging in, remove the battery and keep it in a cool place to avoid heat loss.

4. Battery Care:

To do a deep cycle, charge your battery to its maximum capacity, then cool for two hours after charging.

Once your battery reaches 5%, unplug your power cord and set your computer’s energy-saving settings to hibernate.

Wait five hours after your computer hibernates before connecting to the power wire and charging at full capacity.
