What percentage of power is left on the laptop to start charging

When the laptop prompts that the battery is low, it can be charged at the right time. Know.

Laptop battery maintenance method:

At present, many laptops use the activation type, which means that the battery of a new notebook should have 3% power when it is turned on for the first time (which is also generally introduced in the manufacturer's manual), at this time, you should not use the external power supply first, and use up the remaining power in the battery until it is turned off, and then charge it with the external power supply. After returning home, you should also use up the battery to recharge, and the charging time must be more than 12 hours, repeat it three times in order to activate the battery, which can lay a good foundation for future use.

Minimize the number of times you use the battery. The number of charging and discharging of the battery is directly related to the life, every time it is charged and discharged, the battery will consume a small part of the life, this principle should be clear to everyone, for example, the newly bought mobile phone can be used for a long time when fully charged, but after a period of use, you will find that the use time is obviously not so long, it is the same reason, so we recommend that you try to plug in the external power supply when there is an external power supply, do not use the battery to power supply, so as not to affect the battery life of the notebook.

Most laptops have their own power management system, which intelligently prompts your computer to charge. It is best to charge it according to the prompts. If your computer doesn't have this kind of prompt, it's best to recommend that you start charging it when your computer is about 7% in use.

Usually it takes 2 to 4 hours.

The standby time of the 4-cell battery is about 2 hours, and the use time is about 1 hour; The standby time of the 6-cell battery is about 3 hours, and the use time is about 2 hours; The standby time of the 8-cell battery is about 4 hours, and the use time is about 3 hours; The standby time of the 9-cell battery is about one hour, and it can be used for about one hour.

The new laptop battery charging time should be around hours to fully charge to 100%. When the battery utilization rate is gradually decreasing, the time to fully charge and the time to consume power will also become shorter and shorter. This is a phenomenon of reduced battery life.

Laptops generally have less than 15% of the battery left, so they have to be charged quickly.

The power loss of laptop batteries (lithium-ion batteries) is proportional to the number of times it is fully charged and discharged, so when using the battery to work, do not consume less than 15%, it is best to charge it quickly when it is close to 20%, and the battery power will be about 5% loss once the red light alarm. So don't wait for the battery to be low and alarm before charging.

How do I protect my computer battery?

When using a laptop with an external AC power supply, whether the battery should be removed depends on the personal use and usage environment.

1. If you often need to use it on the go, or the power supply of the computer environment is not.

Normal, and you do not have an external UPS uninterruptible power supply, it is best to connect the battery, so as to protect the computer, after all, thousands of laptops are still cheaper than the loss of a battery.

Some models of notebooks do not have a battery compartment cover, and a large piece of the fuselage will be missing after removing the battery, which will affect the aesthetics; There are also some laptops whose batteries are also designed to function as counterweights, which may affect the balance of the body after being removed.

2. The life of the battery is determined by the actual number of charging and discharging cycles. Nowadays, many notebook manufacturers have taken into account the fragility of the battery and added battery protection technology to their products, which will only automatically charge when the battery level is less than 95% (some to 99%). This can play a good role in protecting the battery, but because the environment in which the lithium battery is located is impossible to be absolutely insulated, and the control circuit is integrated in the battery, the battery will gradually discharge even when the computer power is turned off, and when the AC power is connected again, the battery will start to charge, which will reduce the life of the battery to a certain extent; In addition, the heat generated when the computer is working will also affect the battery life.

Therefore, in the case of stable power supply in the computer use environment, it is recommended to remove the battery and use the power adapter for power supply alone.

3. The ambient temperature should be between 15-30 degrees Celsius and kept in a dry and ventilated place. When the power drops to 3% 6% to carry out a charge, the test shows that charging 40-50% power preservation effect is the best.

It is best to take out the battery once a month to use it, which can not only ensure the good preservation state of the battery, but also prevent the battery from being completely lost and damaged.

Summary. It's better to play with the laptop on charge. The life of a battery is measured in the number of times it is charged and discharged.

If you don't unplug it, the laptop will automatically use the power provided by the power adapter instead of using the battery's power to cause the charger to continue charging the battery. If you unplug the charger after it is fully charged, the laptop can only use the battery, which increases the number of times the battery is charged and discharged, and the laptop will reduce its performance when using the battery. It's better to keep 80% and 90%.

The laptop is always charged for gaming, how much power is best to keep?

Can you tell us more about that?

It's better to play with the laptop on charge. The life of a battery is measured in the number of times it is charged and discharged. If you don't unplug it, the laptop will automatically use the power provided by the power adapter instead of using the battery's power to cause the charger to continue charging the battery.

After being fully charged, unplug the charge and make a complete device, resulting in the notebook can only use the battery's power, which increases the number of times the battery is charged and discharged, and the laptop will reduce its performance when using the battery. It's better to keep 80% and 90%.

The current when charging the laptop is about 3A, and the voltage is 19V Power: 19x3 = 57W, 1000 57 =, so it is about one kilowatt-hour continuous charge, and it can be fully charged in more than 3 hours, and the current is gradually decreasing, and it takes one kilowatt-hour to fully charge the laptop battery.

The power consumption of the notebook mainly depends on the power adapter, generally Lenovo's power adapter is 65W 90W, 1 kWh = 1000W H, so the power consumption per hour is kWh.

This can be calculated, the current when charging the laptop is about 3A, and the voltage is 19V power: 19x3 = 57W, 1000 57 = So about one kilowatt-hour continuous charge, it can be fully charged in more than an hour, and the current is gradually decreasing, so it will not use so much electricity!

The capacity of each notebook is not the same, for example, a battery information is like this: voltage 5600mah, the two multiplied is 62wh, and the kilowatt-hour is 1000wh, then the battery is the kilowatt-hour of electricity, divided by the charging efficiency, which is the actual power consumption, and the conversion efficiency of the laptop power adapter is generally about 80%.

The time when the laptop starts charging is not very important, because it uses a lithium battery, which can be charged at any time, and can be charged at any time when the user needs it and is convenient.

The weight of a laptop usually weighs 1-3 kg. The trend is to be smaller and lighter, but more powerful. Like a netbook, which is commonly known as a netbook.

The main difference between a laptop and a PC is its portability.

Business laptops are generally characterized by high mobility and long battery life; Fashionable and special appearance, there are also stylish laptops suitable for business use; The multi-application note-taking computer is a combination of powerful graphics and multi-processing power and a certain degree of mobility.

Note: 0% of the battery is very easy to damage the battery, and it should be avoided as much as possible!
