What's the reason that your laptop battery can’t be charged?

Many people may ask the reason and solution of charging failure of laptop. There are normally four reasons for charging failure of laptop, including adapter failure, battery failure, mainboard failure and circuit fault. But how can we solve this problem?

【Laptop battery rechargeable battery 】  the reason of the notebook battery charging failure

A: the power adapter failure

Power adapter has a lot of friends called charger, though not very accurate, but also is very image. Judgment is caused by the power supply is not charging is simple, can replace method. This fault in the DELL notebook maintenance, DELL laptop using LBK (DELL architecture), charging circuit design is special, and adapter will not charge if problems arise, if not the original adapter will not charging problems. In HP slightly new laptop have greater model adopted the charging circuit, more classic fault is absolutely HPNX6400CPU utilization is also caused by power failure.

2: the battery failure

Laptop battery failure performance is simpler, more is charging schedule has been showed that 100%, actually a cut off the power adapter battery life is less than a few minutes, or directly detect battery. Is mainly due to normal wear and tear of the battery itself, laptop battery, drive, fan these three in notebook accessories is truly "consumables".

Related clew: laptop computers even when power off, also remain the state of power batteries, used to maintain the basic standby voltage on the motherboard. Once connected to the external power supply, battery will automatically start charging by default. There are a lot of laptop is not often move in your office or home, but since the batteries installed in the machine for a long time, always circulation charge and discharge, also seriously affect the service life of the battery. Some people say his laptop battery is almost never used alone can't be used a few times, it is for this reason. So the laptop for a long time without words must take down the battery, the power control in 40%, and stored in 15 ℃ or lower temperatures.

Fault judgment is the replacement method, sometimes can't find the same type of battery you need to the professional notebook repair center for help. In our maintenance business before there is a laptop battery core replacement, is the laptop battery maintenance. Along with the popularization of notebook computer, the price of the laptop accessories also have become to let consumers to accept, change the OEM batteries and battery changes core price difference is not very big, so the general directly it is ok to change the battery, the price of the original laptop battery is probably in 1/10 of the price of the laptop, performance advantages, of course, you don't have to say more, choose OEM or original to weigh the pros and cons on your own.

Three: the mainboard failure

Mainboard failure caused by the notebook is not charging notebook maintenance encountered in the most, because it is to do the maintenance of chip level, caused the general power supply and battery not charging in the hands of board-level maintenance man can solve, not to our hand.

Motherboard failure also has two kinds of circumstances, from easy to difficult, in turn, is that the power - power circuit fault say first mouth, this relatively simple, sometimes off when the battery is not, charging power continued, with the hand move power supply can judge, then there is the battery and motherboard interface virtual welding can also cause not charging failure.

Four: circuit fault

Usually charging circuit and protection of isolating circuit fault occurs.

In addition to the chip is easy to damage, damage to the peripheral circuit is also a lot. As a smaller than sesame seeds Zener diode, in early repair work, no circuit diagram and the figure of point, such as fault is quite time consuming.

And the EC itself and peripheral circuit fault, EC is charging IC supervisor circuit, is responsible for opening and closing charging circuit, here is not doing fine.

Daily checking is not charging the performance of this fault and fault points more than the above several, if your laptop also appeared the fault, you can read this article, if still cannot solve the query to the net more the cause of the problem.

Laptop battery charge it into electricity?

1, check the battery and see if lines appeared loose, not firm connection problem.

2, if the line is normal, see if the battery charger circuit board is broken, change a try.

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

4, general battery for three years or so, basic aging, even the lithium battery, you can go to the repair shop under test.

5, batteries commonly used by about 20%, you need to recharge, don't wait to be 0, recharging, too hurt the battery.

6, Solution: use napkin to wrap the battery, pay attention to package for several layers, and then glue with a transparent twisted cloth in the outside. Seal with twisted cloth tightly, don't let the water go inside, and then put in the refrigerator (2 - minus two degrees Celsius). Take out after 72 hours, and the battery may restore some storage function
