My notebook Lenovo s, just bought a few days Why does the battery drain fast and charge quickly

The recharge capacity of the notebook is basically about three hours, which is normal if it is within this range. I don't know what kind of fast method you said about using electricity?

What is the concept of fast? Describe exactly how long it will take.

How long does it take, if you use the battery to play games, the power will definitely wear out quickly, and the battery quality problem will be considered for new machines.

1. The remaining battery time (power) prompted by the system is only an instantaneous reference value, and the actual battery life time is directly related to the operation of your current computer

1. Reduce the brightness of the screen, reduce the use of built-in optical drives and speakers.

2. Turn off idle wireless network cards, Bluetooth devices, etc.

3. Adjust the power consumption mode to "energy saving" and "balanced".

Second, the battery is a consumable product, it is normal to have a certain amount of loss, and after a period of use, the battery life will become shorter and shorter. You can try to correct the battery level by fully charging and discharging the battery, here's how:

1. Unplug the external power supply, turn on the battery only and enter the BIOS.

2. Wait for the battery to run out until it automatically shuts down.

3. Plug in the external power supply, turn on the machine normally, and continue to charge until the power is fully charged to 100%.

3. Regardless of whether the battery is installed in the computer or not, there will be a phenomenon of self-discharge (about 1% a day, slightly different according to different models).

4. If the above three situations are excluded and the laptop battery is still draining quickly, it is recommended that you consider repairing and replacing the battery.

1. The reason why the laptop consumes power quickly:

1. There are too many programs that the computer reopens at the same time, resulting in fast battery consumption.

2. There is too much dust inside the computer, and the heat dissipation is not good, so check whether the working frequency of the heat dissipation device is normal.

3. The battery is old, and the capacity is significantly reduced, which greatly reduces the actual use time of the battery, and you can go to the maintenance center to replace the battery.

4. The computer can be set to power-saving mode to reduce the CPU working frequency to reduce battery consumption, but the symptoms are not cured, and the power supply IC may be affected by the rapid power consumption for a long time.

2. Solution:

1. Maintain the laptop's battery.

Don't keep plugging in the power supply for a long time, in addition, don't wait until the battery is exhausted and shut down before charging, and plug in the power cord as soon as possible for the remaining 10 or so, which is the most conventional maintenance method;

2. In the absence of an external power supply, it is best not to play games or watch movies, because these programs consume power quickly;

3. Unplug the external equipment, such as a mobile hard disk or U disk inserted into the computer, although the power consumption in this situation is not too large, but the accumulation will also affect the power of the computer.

4. Go to the maintenance center to replace the original battery, which is not expensive and the maintenance speed is fast.

Mine is the Lenovo G745. It's not the same model as you, and it's best to plug it in when you're using a laptop. Use batteries when you're away from home. Otherwise, it won't take long for the power to turn off. It takes about an hour to fully charge the battery.

Reasons why laptops drain their batteries fast:

1. The battery is used for too long and the performance is reduced;

2. There are many programs on the computer (such as sound, picture brightness, opening a lot of background programs, etc.), which are serious power consumption.

3. It is recommended to go to the repair center to replace the laptop battery for extended use.

1. Learn to maintain the battery

The maintenance of the battery is very critical, do not use the battery to no longer charge, the current notebook and mobile phone do not need to discharge the operation, as long as you remember to charge it in time when there is almost no power, reduce the number of automatic shutdowns.

2. Adjust the brightness of the screen

The brightness of the screen also has a lot to do with the use of power, we can use the brightness adjustment button on the laptop keyboard to adjust (different computer keys are different) The brightness setting is lower, and the electricity consumption will be less naturally.

Using the battery to play games, it is very fast to use, generally speaking, the battery life of 2-3 hours can only play for about an hour and a half, it is recommended to play games when it is plugged in (and do not worry about running out of power).

This power mode setting problem is mainly to extend the battery life, you can change the power mode option yourself.

1. In the control panel.

Select the power option for hardware and sound.

2. Click any one to change the plan settings.

3. Select Advanced settings for changing the power supply in the drier section.

4. Click Lenovo Power Management again to start Lenovo power management software.

5. Click on the icon of battery and gear in the lower right corner to enter the chain setting.

6. Here you can choose the battery full charge mode and battery maintenance mode. Select the battery full charge mode to charge to 100%. If you use the power supply frequently, you should choose the battery maintenance mode.

The battery broke and didn't rush in, replace it with a new battery put hope mine will help you.
