Four causes analysis and solution of laptop battery can't charge electricity

Notebook battery can not charge four kinds of reasons analysis and solution. Many netizens will ask, what is the reason that the notebook battery does not charge into the electricity? What about the laptop battery not charging? 4 kinds of reasons for not charging notebook batteries are power adapter failure, battery failure, motherboard failure, circuit failure. So how do we solve the problem of laptop battery not charging?

One: Power adapter failure

The power adapter has many friends called the charger, although not accurate, but also really very image. It is also simple to judge whether the charge is not charged because of the power supply and the substitution method is possible. This failure is more common in Dell notebook repair, Dell notebook with LBK (Dell structure), charging circuit design is more special, if the adapter problems will not charge, if not the original adapter will also appear without charging problems.

Some newer laptops in HP also have more models using this charging circuit, compared to the classic failure of HP NX6400 CPU occupancy rate is due to power failure.

Second: Battery failure

Notebook battery Failure performance is relatively simple, mostly charging progress has been shown 100%, in fact, a power adapter to remove the endurance of less than a few minutes, or directly detect the battery. Mainly because of the normal loss of the battery itself, notebook batteries, optical drives, fans of these three in the notebook accessories is a veritable "supplies".

Related tips: Even when the laptop is powered off, the battery is always in a power-consumption state to maintain the basic standby voltage on the motherboard. Once connected to the power supply, the battery will automatically start charging by default. There are many notebooks in the office or home is not often moved, but because the battery is installed on the machine for a long time, always cycle charge and discharge, but also seriously affect the life of the battery. We have encountered many of these in the maintenance of notebooks, the customer said that their notebook batteries have been used few times alone can not use, this is the reason. So if the notebook is not moving for a long time, be sure to take the battery down, its electricity control in 40%, and stored in 15 ℃ or even lower temperature can be.

Fault diagnosis is also the substitution method, sometimes can not find the same type of batteries need to go to the professional notebook repair center to seek help. Previously in our repair business is a notebook battery core replacement, is the notebook battery repair. With the popularity of notebook computers, the price of notebook accessories has become able to allow consumers to accept, and replace the OEM battery and battery core price difference is not very large, so the general direct replacement of the battery can be, the original notebook battery price is probably in the notebook price of 1/ 10, of course, the advantages of the performance will not have to say, the choice of OEM or original on your own to weigh the pros and cons.

Third: Motherboard failure

Motherboard failure caused by notebook not charging is the most encountered in the notebook repair, because it is to do chip-level maintenance, general power and battery-induced not charge in the hands of board-level maintenance staff will be resolved, not to our hands.

The failure of the motherboard also has two kinds of cases, from Jane to difficult in turn, power port-circuit failure First said power port, this is relatively simple, performance is not when the battery is sometimes off, when the power off, with manual power supply mouth can make judgments, there is the battery and motherboard interface virtual welding will also cause no charge fault.

Four: Circuit failure

Generally is the charge circuit and protection of the isolation circuit failure. In addition to the chip itself easy to damage, its peripheral circuit damage is also a lot of see. such as smaller than sesame seed regulator diode, in the early repair work, there is no circuit diagram and point bitmap, repair this fault is quite time-consuming. There is the EC itself and the surrounding circuit fault, the EC is the charge IC's superior circuit, is responsible for opening and closing the charging circuit, here is not to do a detailed statement.

The Daily test notebook does not charge this fault performance and fault points far more than several, if your notebook also appeared this fault, you can read this article, if not yet solved on the internet to inquire more reasons for the failure.

Five, notebook battery charge does not enter the electricity to do?

1, check the battery to see if the line appears loose, the connection is not solid problem.

2, if the line is normal, to see whether the battery charger circuit board is broken, for another try.

3, if the line is normal, the charger is good, it may be the internal circuit board of the computer failure.

4, the general battery used for about 3 years, basically aging, even lithium batteries, can go to repair shop under detection.

5, the general battery to 20% or so, you need to recharge, do not wait until 0 o'clock recharge, too hurt the battery.

Save the small way:

Wrap the battery up with a napkin, note that more than a few layers, and then with a transparent cloth and then glued to the outside, pay attention to the use of cloth sticky, do not let the water seepage, and then put in the fridge (2----零下2摄氏度) to save 72 hours later, the battery may restore some of the storage function.
