Should I charge my laptop overnight? How to safely charge a laptop battery?

You do not know how to charge the laptop battery to increase the life of the battery and use it for a long time. Then do not ignore the following article Tnhelearning.edu.vn will provide useful information on whether to charge a laptop overnight and note how to safely charge the battery!

Should I charge my laptop battery overnight?

Laptop batteries now have a pretty good management system built-in, capable of turning off automatically when the battery is 100% fully charged. Therefore, if you charge the laptop battery overnight, it will not affect their durability and longevity.

However, plugging in the charger with a constant frequency can cause the Room in the battery to misremember the empty and full position and reduce the life of the battery.

On the other hand, charging the laptop battery overnight will cause the adapter to work continuously, the temperature will increase sharply and make them fail faster, the charging capacity is no longer as effective as the original.

The hot adapter that comes with high temperature will emit sparks that are easy to ignite with dry paper and cloth, which is the cause of fires due to overnight charging, extremely dangerous.

How to properly charge a laptop battery?

Do not use it while charging when the laptop battery is not full

Using and charging when the laptop battery is not full is an extremely dangerous thing. At that time, the laptop charger works with a much larger capacity than the battery, so the electricity will convert part of the battery and part of the machine, causing the device to heat up and reduce the life of the battery .

Besides, when you use a laptop with high performance, the ability to charge the battery is also reduced because part of the power must be provided to the CPU and GPU, and the power adapter for the machine is only 2/3 or less. 1/2 .

To overcome this problem and ensure the battery life and durability of the device, please plug in the charger to 100% and then use the laptop!

Turn off the device completely until fully charged

To know when to fully charge your laptop, take a look at the following battery levels to charge accordingly:

• Level 5%: This is the lowest percent battery alarm level. When the machine has reported this level, some models will automatically disconnect and put the device to sleep or hibernate to protect the motor, while some models will start to disconnect a few seconds later.
• Level 10%: This is the alarm level of many models, at this percentage your device can still be used for a few more minutes until it turns to 5% and automatically stops. If you want to ensure the durability of the machine and the safety of use, you can actively disconnect the machine.
• Level 20%: At this alarm level, you can extend the machine use time by 10-15 minutes or maybe more depending on the intensity you use.

The first time using the device should charge longer than usual

When you bought a new machine, the machine had to go through a process of transporting it from the factory to the store, so when it arrived, the laptop battery was not 100% intact and was automatically discharged.

Batteries in an inactive state can last up to 60 days , not forever. When you fully charge the battery for a machine equipped with a disconnected indicator light or the signal level in the software 100% is just a status .

For the above reasons, it is recommended that you charge the battery for a longer time than usual for a new laptop that has been purchased for a while.

For example, normally your device needs to be charged for 4 hours to be fully charged, then charge it for about 6 hours for the first time you buy the device (specifically 10-20 times), after that you can charge it for about 4.5 hours . !

Discharge the battery every 3 or 6 months to increase its life

The essence of discharging a laptop battery is to help the battery improve its ability to predict the remaining usage time without causing the battery to drain faster or damage the hard drive. Before discharging the battery, set the laptop’s battery usage mode as follows:

Step 1: Right-click on the battery icon in the Taskbar. Then you click Power Option .

Step 2: You choose Change Plan Settings .

Step 3: At the On Battery section, click Never for all items.

Step 4: Once you have set up the steps according to the above instructions, use the laptop until the battery is about 3% , then click Shutdown the machine.

Step 5: When you have completed the instructions, press the power button to turn on the machine and press the key to enter the BIOS .

After completing the 5 steps to set up the battery mode as above, proceed to discharge the laptop battery as follows:

+ How to discharge the battery (Manual)

Step 1: Please fully charge the laptop battery to 100% .

Step 2: After fully charging the battery, you leave the device in a resting state for about 1 ~ 2 hours , which means that you still plug in the charger but do not use the device or use the device but at low intensity.

Step 3: You unplug the charger and use the device for your needs until about 3% or 5% of the device will automatically disconnect and discharge the remaining energy.

Step 4: After the machine automatically disconnects and discharges the remaining energy, let the machine rest for about 4 ~ 5 hours .

Step 5: After completing the above steps, plug the charger into the device and charge it until it is 100% full.

+ How to discharge the battery (Application)

You also perform step 1 as above, but step 2 , use the built-in battery discharger software (if available) to completely discharge the battery at a faster rate, even 1.5 – 2 times faster. compared to when you run Game, Music, Movie, Software.

It is recommended to use genuine chargers with standard parameters

When buying a laptop, the manufacturer will equip it with a standard charger with appropriate parameters. In the event that you lose the charger for some force majeure reason and you use a replacement charger with a different performance, it may cause the device to catch fire and cause serious damage .

Therefore, when that is the case, go to the store to buy a charger with compatible parameters, even if it is not a genuine charger, it will be safer to use, without reducing the performance of the component. and limit fire.

Plug the charger into a power source before plugging the charger into the laptop

Plugging in the charger in the standard sequence is also one of the measures that contribute to improving the battery’s life. The correct sequence that you need to do is to plug the power charger into the power outlet first and then start plugging the charger into the laptop.

When performing the above sequence, the adapter has a voltage stabilizer to make the incoming current more stable and safer, the charger is not plugged into the laptop, so there is no output to help limit the arc phenomenon.

Limiting the laptop to power down due to running out of battery

Sometimes, you work so focused that you forget to check the battery status of the laptop, leading to the battery draining and shutting down many times due to the battery running out, reducing the life of the battery and the laptop’s durability.

So, the best way to charge the battery to ensure the durability of the laptop battery is that you need to plug in the charger when the device is 10-20% , absolutely do not let the battery drain and self-destruct before plugging it in.
