I read, I changed the adapter will be able to charge the battery, and my adapter can also be charged to other models of the same type of notebook (dell N5110), but their own adapter is not able to charge their own notebook
2 points: either the battery is broken, do not go into the. Or is part of the battery connection is not good (or a problem, and this trouble)
Probably can analyze two cases
1, you can try not to install the battery alone to use the power adapter can be used to prove the normal use of the adapter and the charging interface no problem to determine the battery problem
2, the battery installed with the adapter to charge, look at the computer indicator light charge the amount of no, if the time is not long when the battery is likely to support the power. This is the problem with the power adapter.
If the laptop is still within the warranty period, you can take the sale to detect replacement
Three: motherboard failure
Motherboard failure caused by the notebook is not charging laptop repair is the most encountered, because it is doing chip-level maintenance, the general power and battery caused by the charge in the hands of the board-level maintenance staff will be resolved, not to our hands.
There are two cases of motherboard failure, from simple to difficult is the power port - circuit failure
First said the power port, this is relatively simple, the performance is not when the battery is sometimes power-down, charging off the power, with the hand to move the power port can make judgments, there is the interface between the battery and the motherboard Weld can cause no charge failure The Related content: "laptop power port replacement"
Then there is a circuit failure. Generally, the charging circuit and the protection isolation circuit are faulty. Such as the common charging IC MAX1772 (Quanta foundry models) ADP3860 (classic IBM models commonly used in the charging chip).
In addition to the chip itself is easy to damage, the surrounding circuit damage is also seen. Such as saponins smaller than the regulator diode, in the early maintenance work, there is no circuit and point map, repair this failure is quite time-consuming.
There is EC itself and the surrounding circuit failure, EC is the charge of the IC's higher-level circuit, is responsible for opening and closing the charging circuit, do not elaborate here.
Two: battery failure
Battery failure performance is relatively simple, mostly charging progress has been shown 100%, in fact, a power adapter to get rid of less than a few minutes, or can not directly detect the battery. Mainly due to the normal loss of the battery itself, laptop batteries, CD-ROM, fan, which in the three parts of the notebook count is worthy of the "supplies" of the.
Related Tips: Notebook computer even when the power is turned off, the battery is always in a power state, used to maintain the basic standby voltage on the motherboard. Once connected to an external power supply, the battery will automatically start charging by default. There are many notebooks are not often moved in the office or at home, but because the battery is long installed on the machine, always cycle charge and discharge, but also seriously affected the battery life. We encountered a lot of laptop repair this situation, the customer said his laptop battery almost did not use a few times can not be used, is the reason. So the notebook does not move for a long time, then the battery must be taken down, its power control at 40%, and stored at 15 ℃ or even lower temperature can be.
Fault judgment is to use the replacement method, and sometimes can not find the same type of battery you need to go to the professional laptop repair center for help. Previously in our maintenance business there is a laptop battery replacement, is the laptop battery repair. With the popularity of notebook computers, the price of notebook accessories have become able to allow consumers to accept, change the OEM battery and battery battery for the price difference is not great, so the general direct change the battery on it, the original Notebook battery price is probably in the notebook price of 1/10, of course, the advantages of the performance do not have to say, choose OEM or the original on your own to weigh the pros and cons.
One: The power adapter is faulty
Power adapter has a lot of friends called the charger, although not accurate enough, but it is indeed very image. Judgment is not due to the power supply is not charging is also very simple, the replacement method can be. This failure in the DELL notebook repair more common, DELL notebook with LBK (DELL architecture), charging circuit design is more special, if the problem will not charge the adapter, if not the original adapter will not charge the problem. HP slightly new notebooks also have more models using this charging circuit, the more classic failure is HP NX6400 CPU occupancy rate is 100% due to power failure caused.
