Q:Hello, my laptop power adapter can be used directly but can not charge the battery
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.

Q:Laptop power adapter must match?
but the rated power is too low, you can change the higher power, but never for a lower, the original 90w you will change the 65w power shortage, often restart Is a normal result, like the desktop power supply power is not the same as the power will restart, only in the energy-saving mode (safe mode and u disk pe system also) can barely use, can not play large games or other large software, long time
Q:Notebook power adapter why there is no cooling hole
Notebook adapter due to the portability often need to move in order to avoid dust and water stains and other notebook power adapter are sealed, of course, the most important thing is to avoid leakage because it may be used in bed, such as fear of fiber wire wrapped around It is absolutely impossible for you to drill with a time bomb
Q:My laptop power adapter is broken, the standard is 16V, 3.75A, now there is a 12V, 3A adapter can be used?
The best do not use, to the market to buy a adapter of the same specifications it, in order to a power supply if the laptop broke more worthless!
Q:Lenovo z460 laptop power adapter voltage is how much ah
Standard power supply is 19V 4.25A, 3.42A can also be used, but easy to heat
Q:Original notebook power adapter burned out, the current is the original 3.95A is equipped with 4.74A, you can use it?
Do not be small on the line. The original 3.95A you that is integrated graphics it, alone significant notebook power consumption, the current is large, I was 4.74A
Q:Laptop power supply is bad
Generally the root line is the root and the socket connected to the line and the adapter connected to loose, nothing, the main line from the adapter to pull up in the plug, the general plug point on it. If not for this reason that is connected with the laptop at the loose, it is best to change the adapter
