笔记本维修常见概念详解

显卡门事件就是NVIDIA最近被迫承认的GF8400,GF8600所有显卡存在的硬件缺陷问题。

NVIDIA is the card door events have recently been forced to admit GF8400, hardware defects of all GF8600 graphics.

在唯佳多年的笔记本维修工作中，曾接修过许多某个品牌的某个型号有通病的笔记本。比如当年的机皇IBM T20，通病是开机硬盘灯闪一下即灭，不能开机。这个是由于CPU的核心供电IC ADP3421和ADP3410发生故障所引起的。同样采用这组供电芯片的机型如A21、A22、HP的XE3都会出现相同的故障。

The only good years notebook repair work, a model was then repaired many one brand of common notebook. Such as machine http://www.meiguoqianggeng.com/ emperor was IBM T20, as is the case with the boot disk light flashed out, can not boot. This is because the CPU IC ADP3421 and ADP3410 core power supply failure caused by. Also use this set of power supply chip models such as A21, A22, HP XE3 will appear the same fault.

还有经典的T40当年维修高峰时，USB口不能用的机器每天都有好几台，都不用检测直接更接南桥IC，修复率很高。故障严重点的表现是不加电，这些故障都是由于南桥DBM损坏所引起的。当时采用迅驰一代平台的的笔记本量很大，这种故障也极常见。不过像显卡门这种在保内就出现故障而且更换主板也不能解决问题的确实还是头一次。.其中我们在日常维修中接触最多的是在HP笔记本维修中DV2000 V3000 系列

And the classic T40 year repair peak, the USB port can not use the machine every day several, are not directly http://www.yeyanmaigw.net/ connected with detection of more IC, the repair rate is high. Severe fault point performance is not power, these failures are due to DBM damage caused by. When the notebook is a generation of Centrino platform, this failure is also very common. But like the graphics card door in security on the failure and replace the http://www.jiyinyugeng.com/ motherboard also can not solve the problem really is the first time. In our daily repair. The contact most is in the HP DV2000 V3000 series notebook repair

惠普受影响的产品型号主要为：

Compaq Presario series: v30xx, v31xx, v32xx, v33xx, v34xx, v60xx, v61xx, v62xx, v63xx and v64xx.

常见的客户描述：按开关键后，指示面板上的灯一闪一闪，硬盘灯也亮，却一直不见屏幕显示，也就是常说的笔记本开机黑屏。

The common customer Description: press to open the key, indicating panel lights flashing lights, hard disk, but had not seen on screen display, which is often said that the notebook switchs on the mobile phone screen.

全屏看电影时，突然屏幕定住,声音断断续续，几秒后没有了声音，系统无响应。强制关机,再开机,BIOS LOGO画面出现一条条竖线。主要是由于这两款机器当时出货量很大，其它品牌配置NVIDIA G84和G86系列显卡的笔记本，戴尔、联想、苹果、索尼和其它PC生产商的多种型号的笔记本都受到影响。

Full screen movies, suddenly the screen, sound off, after a few seconds no sound, no response. Forced shutdown, restart, BIOS LOGO screen appears a vertical line. Is mainly due to the two machines when shipments, other brands of configuration of NVIDIA G84 and G86 series notebook graphics cards, a variety of models Dell, Lenovo, apple, Sony and other PC manufacturer of notebook are affected.

其中，戴尔受影响产品型号为：Inspiron 1420、Latitude D630、Latitude D630c、Precision M2300、Vostro Notebook 1310、Vostro Notebook 1400、Vostro Notebook 1510、Vostro Notebook 1710、XPS M1330和XPS M1530。在DELL笔记本维修中最常见到的机型是D630和1400系列。

Among them, Dell affected by product type: Inspiron 1420, Latitude D630, Latitude D630c, Precision M2300, Vostro Notebook 1310, Vostro Notebook 1400, Vostro Notebook 1510, Vostro Notebook 1710, XPS M1330 and XPS M1530. In the most common DELL notebook repair the aircraft is D630 and 1400 series.

故障原因：是其GPU内部的粘合材料在热胀冷缩的时候,伸缩比不同其他材料.于是GPU在每经过一次冷热交替的时候都会有一些松动,产生种种故障，最终报废。这个缺陷在台式机和笔记本电脑的GF8400,GF8600全系列都有。 NVIDIA针对此问题曾发布过新的驱动软件，以通过驱使系统风扇提前运行以降低显示芯片散热压力，控制GPU核心温度变化过快来实现保护笔记本，但这毕竟只是权宜之计，治标不治本。―引自《百度百科—显卡门事件》

Fault: is the adhesive within GPU when the thermal expansion and contraction, expansion is different than that of other materials. So GPU in each passing an alternating hot and cold will have some loose, resulting in various fault, end of life. GF8400 this defect in the desktop and notebook computer, GF8600 series have. The NVIDIA for this problem has published new drivers, to run in order to reduce the display chip cooling pressure ahead of time through the driving system fan, control GPU core temperature changes too quickly to protect the notebook, but it is just a matter of expediency, not cure. - from "Baidu Encyclopedia - card door event"

早先在这批机器刚进入维修期的时候，由于没有经验，当时我们的返修率居高不下，曾前所未有的出现过一百天质保期内一台机器返修6次的记录。BGA加热不行，重新埴珠不行，更换芯片还是不行，换了主板也仅是过了一年故障依旧。后来通过自己的总结和同行间的技术交流终于做出了一套针对这款有缺陷显卡的维修方法，大大降低了返修率。简单说就是改良散热和升级新版显卡，维修后用户尽量不玩大型游戏，详情请查看《笔记本换显卡》一文。

Earlier in this batch of machine just entered the repair period, due to the lack of experience, when our repair rate is high, had hitherto unknown appeared after one hundred days warranty period inside a machine repair 6 records. BGA heating not, re clay beads not, replace the chip or not, the board also is only one year after the fault is still. Later, technical exchanges through their own summary and peer finally made

a set of the defective graphics repair method, greatly reduce the repair rate. Simply improved heat dissipation and upgrade to the next version of the graphics, repair after the user try not to play a game, please see the "notebook for graphics" one article.

总结：唯佳以一个从业多年的笔记本维修员的角度来看，自显卡门后的笔记本质量明显大不如前，返修率也成了很多维修人员头疼的事，许多人不得不用低价维修不给予保修的方法来招揽客户，客户也觉得价钱低大不了坏了再修。其实不论从那一方的角度来看无异于杀鸡取卵，只看眼前利益。从商家的角度来说，客户用了几天又坏了，是不会来找你保修，但人家下次还会找你吗。从客户的角度来讲，花的钱太少，商家的维修会不会用心去做是个问号不说，主板多次维修也会存在许多隐患，修几次后彻底报废也不是没有可能。

Summary: the only good for a longtime laptop repair technician's point of view, since the explicit Carmen notebook quality was not as good as before, the repair rate is also a lot of repair personnel headache, many people had to use low-cost method does not provide warranty repair to attract customers, customers also feel the price is low not bad and repair. In fact, no matter from the point of view is of no use, only the immediate interests. From the business point of view, the customers for a few days and bad, is not to find your warranty, but they'll find you. From the customer perspective, spending too little money, businesses will not repair intentions to do is a question mark does not say, the motherboard repair many times there are many hidden dangers, repair a few times completely scrapped is not possible.
