This charge is less than 10, and this charge is not enough

Hello! It is most likely that a different power management mode is set. This has its benefits and can make your battery last longer.

I'm also the book of Lenovo. Open the Power Manager. There are two options in battery care: maximum battery life and maximum battery life. I chose the longest battery life, which can charge up to 76%.

The more a lithium battery is discharged, the more the battery will wear out," said Tom Hartley, a professor of electrical engineering at the University of Akron who helps NASA research on extending battery life. Lithium batteries are best in the middle of the charge, in which case the battery life is the longest. ”

First of all, too high and too low power states have the most adverse impact on the life of lithium batteries, while the number of charge and discharge cycles is secondary. In fact, most of the rechargeable times marked on electrical appliances or batteries sold are based on 80% discharge. Experiments have shown that for some laptops, the main thing is that the battery is at 100% for a long time and will soon be scrapped (including my own laptop battery).

From the above, we can summarize the following points to ensure the capacity and life of lithium batteries:

There is no need to charge the lithium battery to 100% full charge, let alone use up the power. If the situation allows, try to keep the battery power near half full, and the smaller the amplitude of charging and discharging, the better;

GM's Chevy Volt EV is designed from the factory to force the battery to be maintained at 20% to 80%, and Apple's laptop's built-in battery may also use this method (including some other laptops and electronics) to increase the number of battery charge-discharge cycles.

Do not use lithium batteries (especially laptop lithium batteries) to work for a long time when the device is using an external power supply. Even if your laptop has good heat dissipation, 100 percent of the battery in the long term is equal to the ** of the lithium battery.

1.If you use an external power supply for a long time for the battery of your notebook, you don't need to charge the battery to about 80% without charging it. Adjust the power options of the operating system, adjust the battery alarm to more than 20%, the battery level should not be lower than 20%, and charge it before it drops to 20%;

2.Laptops or mobile phones, etc., must not let the battery run out;

4.If you're going to travel, fully charge the battery, but remember to charge the appliance whenever you can, and don't wait until the battery dries for battery life;

5.Use a smarter, more power-efficient operating system, such as genuine Windows 7.

Nowadays, people have a lot of electronic devices, and a large number of them use lithium batteries, so it is very practical to ensure battery life. After all, the battery must be disposed of when it is scrapped, otherwise it will cause serious pollution to the environment.

Hope it helps!

What does the battery need to drive

You are the normal wear and tear of the battery.

It's the battery that is worn out and not fully charged.

It's a battery issue, nothing to do with the software.

If you turn off the computer and charge it if it is not full, it means that there is a problem with the charger or battery.

Go directly to Lenovo after-sales to take a look! Take responsibility for your own computer! I can still see the problem professionally, so I can feel at ease! No, if you want to repair it after the warranty period, you have to pay ...... out of your own pocketHehe.

Too many times to charge and that's it.

This is the self-protection of the notebook power management software, the laptop battery has a lifespan, and it will be scrapped when it is fully charged about 2000 times, so the program will not charge the battery when the battery is not very empty.

If you want to protect the battery, it is recommended to set it to "charge below 70%, stop above 90%". It can extend the life of the battery.

This is a normal phenomenon, not a problem, the self-protection of the notebook power management software, the laptop battery has a lifespan, about the number of full charges reaches about 2000 times and it will be scrapped, so the battery is not very empty when the program will not charge the battery.

If you want to protect the battery, it is recommended to set it to charge below 70% and stop above 90%, which will protect the battery.

If you still have questions, you can me

It may be that the reality is not normal, you reinstall the driver to try.

This can be set, my classmate's is also Y460, and his computer can be set to the charging level. You go to the control panel and take a look.

1.This is first to check whether the battery and the notebook are in good contact, if the contact is not good, although you can read the communication data of the battery, you can not charge the battery, at this time you can take out the battery and test the machine more times, insert the battery into the computer If you hear a beep, you can think that the contact has been good, try a few more times, you can rule out the problem of poor contact between the computer and the battery.

2.Or it is recommended to go to the battery seller to get a battery and try it out.

3.If it is confirmed that the contact between the battery and the computer is good, but the battery still cannot work normally, then it is possible that the battery itself has a quality problem, and the possibility of the problem is twofold: first, the circuit board of the battery is damaged or has been short-circuited protection; Second, please contact the dealer.

This should be analyzed on a case-by-case basis, if it is charged to 80%, it cannot be charged, this is because the battery protection program is set in the system, it cannot be charged to 100%, and the option is canceled in the power management there, if it cannot be charged at all, take the charger to other machines to take a look, if it can be used, the problem is on the battery, if it cannot be charged, the charger has a problem.

Laptops often not fully charged are not good for the battery and are not recommended.

How to charge a notebook:

1. After buying a new notebook, there is no need to activate the computer. The so-called activation is a continuous charge for up to 12 hours. Generally, the laptop has been charged and activated by the manufacturer before leaving the factory.

2. The life of the lithium battery of the laptop is limited, and it cannot be charged if the service life of the battery is exceeded. Therefore, in order to maintain the "maximum life" of the battery, it is still necessary to use up the power and recharge it as much as possible.

3. When using an external power supply, do not unplug the battery. The battery is frequently unplugged and unplugged, which will cause some damage to the computer.

4. Do not unplug the power supply when the battery is not fully charged, if the battery is not fully charged, unplug it and then charge it, which is counted as two charges, which will also cause loss to the battery.

5. If there is an external power supply, it is recommended to plug in the external power supply to use the computer. If the battery is fully charged, it will not wear out the battery, so if you use the computer for many hours in a row, you can always connect the external battery and unplug it without being fully charged. Plugging and unplugging multiple times a day, and laptops with batteries, can cause more damage to the battery.

6. Generally, do not start charging after the battery runs out of sleep, and start charging when the power is about 8%.

That should be a battery issue, go to the after-sales service to check it.

It should be normal, and if you charge it while using it, you can only rush to about 98%.

Is it true that the battery runs out quickly after it is charged? Or do you not need it and lose power quickly? And how many amps is your adapter output?

1. First of all, check whether the battery charging is disabled in the laptop battery settings, and some laptop battery management software also has the function of disabling charging, you can check it;

2. It may also be because the battery has been put for too long and has not been used, resulting in poor contact, it is recommended to open the laptop to clean the dust, unplug the power cord and battery, and it may also be solved.

3. If there is no problem with the check settings, then most of the problems with the internal control circuit or battery cell of the notebook win7 system need to be repaired.

4. When some laptop batteries have been used for a long time and are over-discharged, resulting in 0% of the available power supply has been turned on and not charged, and it will be repaired later, even if it is repaired, the battery life and life will not be long, it is best to buy a new laptop battery to replace it.

The most common cause is the aging of the electrical board.

Or the charging port is loose.
