What if the motherboard battery doesn't charge?

Motherboard battery can not charge the reason and solution one:

1. First check whether the computer has been disabled charging function, as long as the switch on the battery will only give the laptop power but can not charge, in this case the battery can not be charged properly, check whether the battery is turned on to prohibit the charging function.

2. If the battery adapter does not have any problems after the test, try to update the BIOS, which can solve some of the more rare problems, of course, different notebooks upgrade the BIOS method is not the same, and some computers are still using pure DOS as an upgrade program.

3. Sometimes the battery can not be charged when the "cannot determine the type of AC power adapter" prompt box, so in this case we first check whether the charger is the original, adapter power is not normal, if the problem will be replaced in a timely manner.

4. If the problem is the adapter, then look at the power of the adapter, the current notebook charger general "round needle" type adapter in the middle of the needle will have the ability to identify the power of the needle, if there is any problem with the needles hurriedly to repair it.

5. Let's see how much the battery is now, if the electricity is sufficient to charge is very normal, because the notebook in order to protect the battery life is not frequent charge, usually only under 90% of the time will automatically charge, and some laptops can also set the percentage of the lower charge to automatically charge.

The reason of the motherboard battery cannot charge and the solution method two:

There are three reasons why the battery is out of order, the power adapter is faulty, and the power module on the laptop motherboard is faulted. First, eliminate the source of the fault, unplug the battery, only use the power adapter to boot, if the normal power supply is the adapter and the motherboard is no problem, if the failure is still likely to be a power adapter or motherboard problems, this time, try to use battery boot, if the battery and power is the same reason can not be a smooth boot, It may be a problem with the laptop board.

Notebook batteries used too long, or idle too long will appear to be unable to charge the situation, there is no good way to change the battery bar. Laptop batteries have more built-in control chips, sometimes collisions, or low temperatures can also cause damage to the battery.

The failure of the power adapter may be the current is not stable, plug the power of the moment when the instantaneous high-voltage current damaged the adapter.

Motherboard failure is similar to the power failure, but more is the internal dust accumulated in the notebook caused by poor heat caused by high temperature welding components.

The most effective way to eliminate the failure of the power adapter or motherboard is to use the replacement parts to do the testing, recommend to the After-sale repair center to do the test is relatively good, generally this fault detection is free of charge.

Misunderstanding one: Notebook batteries do not need to use all the power to charge

Today's laptop batteries are lithium-ion batteries, and for lithium batteries, the battery is long enough to have no effect at all, or even harmful. Because lithium batteries do not have the so-called "caching effect", only the early nickel batteries have this feature. The life of a notebook battery is usually only related to man-made damage or natural life. Basically, the battery life is fixed, 300-600 times the number of charge and discharge, generally usable for 2 years.

Mistake two: When the power is connected, the battery can be unplugged can not pull

Pull or not pull depends on the actual use of: the connection between the DC power without removing the battery on the battery does not hurt, because the battery is full of electricity will no longer accept any electricity injection, electricity will be all directly to the notebook power supply system. But when the notebook is running at a high speed, it is best to remove the battery when it is overheating, otherwise it is harmful.

How to save a laptop battery that is not used for a long time

is the notebook battery light or should it be full of electricity to save? Long-term storage of light electricity will lose the activity of the battery, even lead to control circuit protection from the lock and can not be used, full of long-term preservation of electricity will bring security risks, the best way to save is the use of electricity to about 40% and then save in a cool dry place, About 20 degrees Celsius is the ideal storage temperature. Of course, every month it is best to take out the battery to use once, not only to ensure a good battery state, and not to let the total loss of electricity and damage the battery.
