笔记本电池不充电是在笔记本维修中较常见的故障之一，现在唯佳就来讲讲常见的不充电的原因及解决办法。

Laptop battery is not charging is one of the more common in the notebook repair in

the fault, now only good will come about / not charging the

common causes and solutions.

现在笔记本已经不是什么奢侈的电子产品，实际上已是办公和生活中不可缺少的工具。选择它是因为小巧便捷移动方便。但是随着使用时间的增加，笔记本电池的续航时间渐渐减少，或是有的干脆不充电。直接换块新的吧，一块电池要好几百，而且有时也不一定就能解决问题。

Now the notebook is not what luxury electronic products, office and has actually is

an indispensable tool in life. It was chosen for convenient mobile convenience. But

with the increased use of time, notebook / battery life

gradually reduced, and some simply do not charge. Directly for the new block, a

battery to hundreds, and sometimes may not necessarily be able to solve the

problem.

笔记本电池不充电的原因简单来说有三个，分别是电源故障、电池老化、主板故障。修复的难度依次递增。

Causes of laptop battery is not charging simply have three, respectively is the power

failure, cell aging, motherboard / failure. The difficulty in

increasing order of repair.

有一点有必要说明，笔记本的充电可以完全脱离操作系统。只要主板、电源适配器、电池三者工作正常就能够完成充电。如下图所示：

A necessary explanation, laptop charging can be completely separated from the

operating system. As long as the motherboard, power adapter, battery three work

can finish charging. As shown below:

在我们接机维修中一般都是电池无法识别或是充电进度一格都不走的情况居多，由于电池续航时间变少送修的数量少些。因为这种情况多是电池芯老化所引起的，平时要多注意电池的保养，详细请阅读《笔记本电池保养和使用》一文。

In our machine repair in general are not recognized or mostly battery charging

schedule one didn't go, because the number of less battery life less repair. Because

of this situation is the battery core caused by aging, usually pay more attention to

the maintenance of the battery, please read "the notebook battery maintenance and

use of" one article.

下面就以不识别电池和完全不充电两个故障现象来说明一下具体的原因和解决方法。

Here is not to identify the cells and not charging two fault phenomenon to explain

the specific reasons and solutions.

一：电源适配器故障

A: power adapter failure

电源适配器有很多朋友称之为充电器，虽然不够准确，但也确实很形象。判断是不是由于电源引起的不充电也很简单，替换法就可以。这种故障在DELL笔记本维修中多见，DELL笔记本采用LBK(DELL架構)，充电电路设计比较特别，适配器如果出现问题会不充电，如果不是原装的适配器也会出现不充电的问题。在HP稍新一些的笔记本中也有较多的机型采用了这种充电电路，比较经典故障的是HP NX6400 CPU占用率百分百也是由于电源故障引起的。

The power adapter has a lot of friends called charger, though not accurate, but also

really image. Judging Is it right? Because power caused by not charging is also very

simple, you can replace the method. This failure is more common in DELL laptop

repair, DELL notebook using LBK (DELL), a charging circuit design in particular,

adapter if problems can not charge, if not original adapter will not charge problem.

In HP a new books have more models using the charging circuit, compare the classic

fault is HP NX6400 CPU occupancy rate is 100% is due to power failure.

二：电池故障 Two: the battery failure

电池故障表现比较简单，多是充电进度一直显示100%，实际上一去掉电源适配器续航时间不到几分钟，或是直接检测不到电池。主要是由于电池本身的正常损耗，笔记本电池、光驱、风扇这三样在笔记本配件算的上是名符其实的“耗材”了。

Battery failure is relatively simple, is charging schedule has been shown in 100%,

remove the power adapter life time less than a few minutes, or directly can not

detect the battery. Mainly due to normal wear and tear of the battery itself, laptop

battery, drive, fan the three samples in notebook accessories are live up to one's

name "supplies".

相关提示：笔记本电脑即便是在关闭电源时，电池也始终处于耗电状态，用来维持主板上的基本待机电压。一旦连上外接电源，电池便会在默认情况下自动开始充电。有许多笔记本是放在办公室或家里不常移动的，但由于电池长期装在机器上，始终循环充放电，也严重影响了电池的使用寿命。我们笔记本维修中遇到过很多这种情况，客户说自己的笔记本电池几乎没单独使用过几次就不能用了，就是这个原因。所以笔记本长时间不移动的话一定要把电池取下来，将其电量控制在40%，并存储在15℃甚至更低的温度下即可。

Tips: notebook computer even when the power supply is switched off, the battery is

always in a state of power consumption, to maintain the basic standby voltage on

the motherboard. Once connected to external power supply, the battery will start

charging automatically by default. There are many notebook is placed in the office or

home do not often move, but because the battery is installed on the machine, always

charge discharge cycle, and the battery life seriously affected. In this case we

encountered many notebook repair, the customer said laptop batteries own hardly

alone a few times can not be used, and it is for this reason. So the notebook long

time does not move then must take off the battery, the power control in 40%, and

stored at 15 ℃ even lower temperature.

故障的判断也是用替换法，有时不能找到相同型号的电池就需要到专业的笔记本维修中心寻求帮助了。以前在我们的维修业务中有一项是笔记本电池芯更换，就是笔记本电池维修。随着笔记本电脑的大众化，笔记本配件的价格也已变得能够让消费者接受了，换个OEM的电池和换电池芯的价格差的也不是很大，所以一般直接换块电池就可以了，原装笔记本电池的价格大概是在笔记本价格的1/10，当然性能上的优势就不必多说了，选择OEM的还是原装的就靠您自己来权衡利弊了。

Fault judgment is used in substitution method, sometimes can not find the same

type of the battery on the need to go to the professional notebook repair center for

help. Before our repair business in there is a laptop battery replacement is the core,

laptop battery repair. With the popularity of notebook computer, notebook

accessories price has become so that consumers can accept, change the OEM

battery and battery core price difference is not very big, so the general directly

change the battery can, original laptop battery price is probably in the notebook

prices 1/10, of course, on performance. The advantage is obvious, choose OEM or

the original rely on your own to weigh the advantages and disadvantages.

三：主板故障

Three: motherboard failure

主板故障引起的笔记本不充电是笔记本维修中遇到最多的，因为是做芯片级维修，一般的电源和电池引起的不充电在板级维修员手中就会解决，不会到我们手上的。

The motherboard failure caused the notebook is not charging notebook repair

encountered in most, because do the chip level repair, the general power supply and

battery caused by not charging solution in board level repair in hand of the member

will, not to our hands.

主板的故障也有两种情况，由简到难依次是，电源口－电路故障

Motherboard fault has two kinds of situations, from simple to difficult is in turn,

power port circuit fault

先说电源口，这个比较简单，表现是不用电池时有时掉电，充电时断电续，用手动动电源口就可作出判断，还有就是电池与主板的接口虚焊也会引起不充电故障。相关内容有：《笔记本电源口的更换》

Said first power port, this relatively simple, performance is sometimes power down

without the battery, charging power continued, hand move power port can judge,

there is the interface of weld battery and mainboard can also cause not charging

fault. Related content: "to replace the laptop power supply port"

再就是电路故障。一般是充电电路和保护隔离电路出现故障。如常见的充电IC

MAX1772（广达代工机型）ADP3860（经典的IBM机型中常用的充电芯片）。

Then the circuit fault. The general is a charging circuit and protection circuit failure.

Such as the common charge IC MAX1772 (type ADP3860 (quanta) charging chip

commonly used classical IBM model).

除了芯片本身容易损坏外，其周边电路的损坏也很多见。如比芝麻粒还小的稳压二极管，在早期维修工作中，没有电路图和点位图，修这种故障是相当的费时间。

In addition to the chip itself is easy to damage, damage to the peripheral circuit is

also very common. Such as sesame seeds also small zener diode, in early repair work,

there is no circuit diagram and bitmap, repair the fault is quite time consuming.
