Answer: Is the laptop battery charged on or off?

Today's notebooks have a complete power management circuit and charging management system, when the laptop battery reaches a saturated state, the control circuit will automatically switch to the open circuit state, so charging for 12 hours or even longer, there is no point. If the charging time is too long, this will lead to too high heat during charging, which will cause phenomena such as **. There are also certain safety risks.

The current batteries are lithium batteries, and lithium batteries have no memory effect, so it is not necessary to charge them after they are discharged like nickel-metal hydride or nickel-cadmium batteries. Deep discharge will unnecessarily shorten the service life of the battery, and it is recommended that the battery can be charged when it is used to about 10%.

Now the power control circuit of notebooks is designed to charge when the battery reaches 90% or 95%, and the time to reach this capacity through natural discharge is 2 weeks to a month, and when the battery is idle for about a month, it must be fully charged and discharged to maintain the capacity of the battery. If you want to use the battery for a long time, try to keep the battery in a dry and low temperature environment and let the remaining battery power be about 40%. Of course, it is best to take out the battery once a month to use it, which can not only ensure the good storage state of the battery, but also prevent the battery from being completely lost and damage the battery.

In short, normal use is enough, the computer has a life, the battery also has a life, do not damage the life of the machine in order to preserve the battery.

The difference between charging and charging the laptop battery is not big whether it is charged on or off, because the laptop is powered by power at this time.

1. It is okay to turn on and off the laptop when charging, because the lithium battery has no memory effect. But if it's a new battery, first.

After the first and second discharge, charging for a longer time will be conducive to the full activation of the battery cell. Of course, in order to prevent the battery voltage from dropping too low, it is best to start charging before the computer shuts down automatically.

2. Generally speaking, when charging the laptop, it can be fully charged in about 2 to 3 hours, of course, for the service life of the laptop battery, it is also necessary to pay attention to the maintenance of the laptop battery during daily use.

Laptops generally don't need to be turned off when charging. However, special actions are required in the following cases:

1. When you use a new laptop you just bought, you need to disconnect the external power supply, use the power of the laptop battery, and use it until it is completely out of power and automatically shut down, and then turn on the external power supply to charge it to full. The first three times you need to do this to activate the notebook's high-sensitivity lithium battery. After that, the laptop doesn't need to be turned off when it is recharged.

2. For indoor use, if it is an external power supply when in use, it is best to remove the laptop battery to avoid automatic repeated charging. Then install the battery every three months or so, fully charge and discharge it, which can prolong the life of the battery.

Need.

Laptop.

Shutdown is allowed while charging. After the power is turned off, the power supply continues to charge the battery. Because each charge is charged and discharged once, it is best to observe the power supply charging indicator during charging.

If you find that the indicator light is off, then the battery is fully charged. It's time to unplug it.

The charging process requires continuity. Power outages are not allowed. Because the number of charges has an impact on the battery life, the battery life refers to the upper limit of 800 charging and discharging, so the power failure in the middle is a charging process.

Minimize the number of charging and discharging to prolong the life.

Maintenance method: Do not use in unstable environments, such as in a car. This is very harmful to the hard drive, and can even make the hard drive scrapped.

The same is true when the device is turned off. When the power is turned off and needs to be turned on again, it is best to wait for a minute before turning it on. It is best to turn off the laptop for more than 20 seconds before moving the laptop.

Do not use it in an environment where the temperature is too high or too low, as this will have the greatest impact on the LCD and the battery, and the low temperature should not be lower than 10 degrees Celsius.

It is best not to exceed 30 degrees Celsius in high temperatures. The laptop should be kept away from magnetic materials such as microwave ovens and speakers, which will cause great damage to the hard disk and even make the data of the hard disk disappear. The memory is far away from electronic products such as mobile phones that can generate high-frequency signals.

The computer can be turned on and charged, or it can be turned off for charging. As soon as it is plugged in, it immediately switches to power by power mode. When the power supply is turned on and charged, the power supply needs to supply power to the laptop and the battery at the same time, and the load is larger, and the power supply generates more heat.

When the laptop is running at high speed and the internal is overheated, it is better to turn off and charge a little better, otherwise it is harmful to the battery. When the battery is fully charged, the battery should be used up as much as possible before charging the battery with an external power supply.

No, the adapter is designed to allow normal use while charging. There are power management circuits on the motherboard, and generally the adapter only provides a high voltage, such as 20 volts. After shunting to the motherboard, it will be separated, 5V, 12V, for charging the battery) and so on.

There is also a set of power management modules on the battery to manage the charging voltage and current. and the voltage that supplies power to the motherboard when only the battery is used.

The computer battery also does not need to be turned off and charged, it can be charged while using it, and the computer will not be charged when it is fully charged.
