I bought a Samsung laptop last year and can only charge 80 of the charge

It's not a battery problem, Samsung notebooks have made this function, called battery life extension technology, the principle is to control the maximum charging power of the battery at 80%, in order to reduce the number of battery cycle charging, increase battery life, if you want to turn off this function, you can open Samsung's own easy settings software, or shortcut key fn+f1, after opening it, find the switch of battery life extension technology, turn it off. If you don't have Easy Settings installed, you can also boot up and press the F2 key to enter the BIOS settings, and set it to "Disabled" in the Battery Life Cycle Extension option in the Advanced option, and press F10 to save and exit.

Hello: According to your description, due to the fact that you have turned on the battery protection function of your laptop, please solve the problem as follows:

Press the F2 key to enter the BIOS settings when you boot up, set it to "disabled" in the Battery Life Cycle Extension option in the Advanced option, and press F10 to save and exit.

After a long time, the battery has degraded a little, go and replace it with a battery.

Charger or battery issues. You can inquire at the specialty store.

Uh, probably the internal savings battery is degraded.

It should be that the battery is aging.

There are two possibilities in this situation, one is a problem with the charger and the second is a problem with the battery.

Both of the above methods can restore the battery charge to 100

This is Samsung's personalized plug-in setting, which is to charge the battery to 80% and not charge, effectively improving the life of the battery.

This is the normal wear and tear of the battery, it's okay, mine is now full by default to 95, and it doesn't affect the use.

The reason why the laptop you are consulting is only 80% full is due to the fact that you have the battery protection function turned on, and if you are using the power cord to power the laptop for a long time, it is recommended that you keep the battery charged to 80%.

If you need to use battery power when you're out and about, you can try the following ways to turn off this feature:

1.Click Start-Program-Samsung-BatteryLifeExtender-Battery-Life-Extender to run this program settings;

2.The Samsung screen appears at boot and press F2 to enter BIOS - select Advanced - find Battery Life Cycle Extender, select this item to turn off the Disable item, and then press F10 to save and exit.

Hope the above reply is helpful to you!

In general, there are several common situations:

1.If there is a problem with the data cable, try to change the data cable;

2.If there is a problem with the charger, try to change to a 5V1A or 5V2A charger;

3.Back up your data, flash your phone;

4.Maybe the charging port is not plugged in properly, or there is a problem with the charging port;

5.It is possible that the battery is faulty and cannot be charged.

If you can't do it, contact the manufacturer and return to the factory for maintenance.

Solution: Check if there is a problem with the charger.

If the charger is fine, it is caused by a broken power line.

Use a universal meter to measure whether there is a DC power output at the plug, if not, it must be that the output line is broken somewhere, generally the interface is stripped of the output line interface to check, find the broken place and reconnect it to be charged again.

There is no multimeter Nasun Pi to find a DC bulb, 6-15V can be, if the light is on, Kai Mao is no problem with the line, otherwise according to the above statement.

If you make sure that the input line is not broken, the charger is not broken, remove the laptop battery, plug in the power supply to start the computer, if it can start, the battery charging module is broken, if you can't start the electric hole brain, the power module is broken, and you have to send it for repair.

There are several possible causes of this issue:

1. Poor battery performance (it is recommended to replace the battery first, try to charge it or send it to the service center for testing).

2. If the mobile phone is equipped with a third-party plug-in such as a charging doctor, it is recommended to test it after uninstalling.

3. Try to replace the original charger.

4. Back up your phone's data (**book, SMS, **, etc.) and restore your phone to factory settings.

If the problem still exists, it is recommended to bring the three-pack voucher for the purchase of the phone, and take the mobile phone to the local Samsung service center for professional engineers to help test.
