dell笔记本电池修复

dell笔记本电池修复第一篇dell笔记本电池修复:笔记本电池坏了要怎么修复笔记本狠多人都在使用，有时也会消失一些故障，笔记本电池坏了这可怎么办呢?下面是百分网我给你带来的笔记本电池坏了的修理方法，盼望你喜爱!笔记本电池坏了的修理方法笔记本电脑修理多少钱?信任大家都心中有数了吧!其中，笔记本电池损坏是最常见的事情，下面我们一起来学习它的修理方法：1、用笔记本BIOS中的电池校正功能大家先将自己的笔记本电脑开机，消失界面之后按F2 进入BIOS菜单，再选择Power菜单，此时你能够发现“Start Battery Calibration”选项。

你只需点击再按回车键进行。

这时你会发现你的屏幕颜色是蓝色，并且英文提示你要插上电源充电。

电量充饱之后，它会自动放电，但需要肯定的时间。

当它的电量全部耗尽之后，你只需再次充电，这样电池校正的过程就完成了。

2、让笔记本开机自然放电大家直接进入“电源选项”这个界面，将“电源使用方案”设置为“始终开着”，此时要把“关闭监视器”、“关闭硬盘”转化成最短的时间，同时也要取消全部的电源选项，这样笔记本的电量就会耗尽。

笔记本电池保养方法1、当无外接电源的状况下，如果当时的工作状况临时用不到PCMCIA插槽中的卡片，建议先将卡片移除以延长电池使用时间。

2、室温(20-30度)为电池最相宜之工作温度，温度过高或过低的操作环境将降低电池的使用时间。

3、在可供应稳定电源的环境下使用笔记本电脑时，将电池移除可延长电池受寿命是不正确的。

就华硕笔记本电脑而言，当电池电力满充之后，电池中的充电电路会自动关闭，所以不会发生过充的现象。

4、建议平均三个月进行一次电池电力校正的动作。

5、尽量削减使用电池的次数。

电池的充放电次数直接关系到寿命，每充一次，电池就向退役前进了一步。

建议大家尽量使用外接电源。

6、使用外接电源时应将电池取下。

有的用户常常在一天中多次插拔电源，且笔记本电脑装有电池，这样做，对电池的损坏更大。

DELL D600维修二例(不显示、暗屏)

DELL D600维修二例
来源：迅维网笔记本维修讨论
1、DELL D600不显示维修
外接CRT正常显示，但屏不显示，说明故障出在液晶屏显示电路。

测屏线插座的15脚LCDVCC电压为0V，说明屏的3.3V供电没有到。

下面是LCDVCC电源产生电路：测Q10（为6引脚的N沟场管）的6脚（D极）有3.3V输入，4脚（S极）输出为0V，再测3脚（G极）为5.8V，说明Q10没有导通，损坏，更换Q10后，开机屏显示正常，修复结束。

见图1
2、DELL D600暗屏维修：
检测步骤：
1）先外接一个好灯管，开机灯管还是不亮；又测一下故障机的灯管是好的，
2）测高压板插座的供电情况，没有18V主供电。

说明故障出在主板上，
3）对照PDF图纸，找到屏线插座的10、11、12脚为高压板主供电脚，再一测电压仍为0V，顺着线路找到Q53(6引脚的P沟道场管)测其4脚（S极）有18V 输入，6脚（D极）输出为0V，再测其3脚（G极）为0V，说明Q53没有导通，损坏，更换，再开机正常显示，故障修复。

见图2
说明：如果没有Q53这样的场管，可将其DS积极直接联通也可解决问题。

附上DELL D600的图纸供大家参考。

DELL笔记本电脑快修手册

DELL笔记本电脑快修手册(shǒucè)（内部资料）DELL笔记本经典(jīngdiǎn)故障1 DELL D600、500M的笔记本在国外销的比较多，国内也比较常见，也是dell曾经销量最大的机型之一！出现故障返修的机器较多，主要是设计(shèj ì)、料件和用户使用不当造成的，1、电源接口（JDCIN1）接触不良此电源接口出现问题可造成(zào chénɡ)插上电源不开机也不充电，料件的品质原因2、客户在使用(shǐyòng)中误将电源接口插入串口（实际遇到很多)有很多客户在插电源接口的时候很容易插进旁边的串口（JCOM1）里，造成19v直接串入主板内的接口电路，轻则com口不能使用，直接更换u29（MAX3243）就可以了；严重的可造成不开机(kāi jī)，这就需要更换USIO1（LPC47N254）了。

系用户使用不当造成，根本原因是设计的接口布局不合理造成3、不开机，开机片上的三个指示灯闪几下,就关机了拿到这样的机器，首先可以测一下Q196 的第2pin对地电阻就知道了，红表笔接地，原则上小于1.0k以下就可以判断是网卡芯片u127的pin A14open（虚焊）造成的，直接加焊这个BGA就可以了，客户经常在插拔网线和USB时用力不均所系，根本原因是网卡芯片布局不合理造成4、不能充电先更换电源适配器试试，有时可以解决。

如故障依然，首先要检查mini pci网卡下面的D108有无烧坏，可用万用表检测；如果在刚开机时画面有提示（不能正确识别电源适配器），这就需要更换USIO1. D108、L77。

分析：电源接口接触不良造成19v直接串入电源适配器识别信号（PS_ID）造成。

D600不充电维修：一般的是SMSCIO坏了，导致不能充电，量MAX1645上电感的电压大约为3。

5V左右，因为SMSCIO为1645芯片的控制芯片。

还有可能为电源口的电感和MINPCI的D108坏所致5、插上电源，适配器上的指示灯就灭了此故障为常见，系主板供电部分short造成，检查起来相对容易些，重点检查Q90，多为Q90 pin4 open造成，其次查PQ4、PQ5、PQ8、PQ96.戴尔D600不认网卡，加焊一下网卡就OK。

General Safety InstructionsUse the following safety guidelines to help ensure your own personal safety and to help protect your equipment and working environment from potential damage.NOTE: In this section, equipment refers to monitors.IMPORTANT NOTICE FOR USE IN HEALTHCARE ENVIRONMENTS:Dell products are not medical devices and are not listed under UL or IEC 60601 (or equivalent). As a result, they must not be used within 6 feet of a patient or in a manner that directly or indirectly contacts a patient1.1 SAFETY: General SafetyWARNING: To prevent the spread of fire, keep candles or other open flames away from this product at all times.When setting up the equipment for use:⏹Place the equipment on a hard, level surface. Leave 10.2 cm (4 in) minimum of clearance onall vented sides of the computer to permit the airflow required for proper ventilation.⏹Restricting airflow can damage the computer or cause a fire.⏹Do not stack equipment or place equipment so close together that it is subject torecalculated or preheated air.⏹NOTE: Review the weight limits referenced in your computer documentation before placinga monitor or other devices on top of your computer.⏹Ensure that nothing rests on your equipment's cables and that the cables are not locatedwhere they can be stepped on or tripped over.⏹Ensure that all cables are connected to the appropriate connectors. Some connectors havea similar appearance and may be easily confused (for example, do not plug a telephonecable into the network connector).⏹Do not place your equipment in a closed-in wall unit or on a bed, sofa, or rug.⏹Keep your device away from radiators and heat sources.⏹Keep your equipment away from extremely hot or cold temperatures to ensure that it is usedwithin the specified operating range.⏹Do not push any objects into the air vents or openings of your equipment. Doing so cancause fire or electric shock by shorting out interior components.⏹Avoid placing loose papers underneath your device. Do not place your device in a closed-inwall unit, or on a soft, fabric surface such as a bed, sofa, carpet, or a rug.- 3 -When operating your equipment:⏹Do not use your equipment in a wet environment, for example, near a bath tub, sink, orswimming pool or in a wet basement.⏹Do not use AC powered equipment during an electrical storm. Battery powered devices maybe used if all cables have been disconnected.⏹Do not spill food or liquids on your equipment.⏹Before you clean your equipment, disconnect it from the electrical outlet. Clean your devicewith a soft cloth dampened with water. Do not use liquids or aerosol cleaners, which maycontain flammable substances.⏹Clean the monitor display with a soft, clean cloth and water. Apply the water to the cloth,then stroke the cloth across the display in one direction, moving from the top of the displayto the bottom. Remove moisture from the display quickly and keep the display dry.⏹Long-term exposure to moisture can damage the display. Do not use a commercial windowcleaner to clean your display.⏹If your equipment does not operate normally - in particular, if there are any unusual soundsor smells coming from it - unplug it immediately and contact an authorized dealer or servicecenter.Protecting Against Electrostatic DischargeElectrostatic discharge (ESD) events can harm electronic components inside your equipment. Under certain conditions, ESD may build up on your body or an object, such as a peripheral, and then discharge into another object, such as your computer. To prevent ESD damage, you should discharge static electricity from your body before you interact with any of your equipment’s internal electronic components, such as a memory module. You can protect against ESD by touching a metal grounded object (such as an unpainted metal surface on your computer’s I/O panel) before you interact with anything electronic. When connecting a peripheral (including handheld digital assistants) to your equipment, you should always ground both yourself and the peripheral before connecting it. In addition, as you work inside the equipment, periodically discharge any static charge your body may have accumulated.You can also take the following steps to prevent damage from electrostatic discharge:⏹When unpacking a static-sensitive component from its shipping carton, do not remove thecomponent from the antistatic packing material until you are ready to install the component.Just before un wrapping the antistatic package, be sure to discharge static electricity fromyour body.⏹When transporting a sensitive component, first place it in an antistatic container orpackaging.⏹Handle all electrostatic sensitive components in a static-safe area. If possible, use antistaticfloor pads and work bench pads.- 4 -1.2 SAFETY: General Power SafetyObserve the following guidelines when connecting your equipment to a power source:⏹Check the voltage rating before you connect the equipment to an electrical outlet to ensurethat the required voltage and frequency match the available power source.⏹Do not plug the equipment power cables into an electrical outlet if the power cable isdamaged⏹Norway and Sweden: If this product is provided with a 3-prong power cable, connect thepower cable to a grounded electrical outlet only.⏹If you use an extension power cable, ensure that the total ampere rating of the productsplugged in to the extension power cable does not exceed the ampere rating of the extension cable.⏹If you must use an extension cable or power strip, ensure the extension cable or power stripis connected to a wall power outlet and not to another extension cable or power strip. Theextension cable or power strip must be designed for grounded plugs and plugged into agrounded wall outlet.⏹If you are using a multiple-outlet power strip, use caution when plugging the power cable intothe power strip. Some power strips may allow you to insert a plug incorrectly. Incorrectinsertion of the power plug could result in permanent damage to your equipment, as well asrisk of electric shock and/or fire. Ensure that the ground prong of the power plug is insertedinto the mating ground contact of the power strip.⏹Be sure to grasp the plug, not the cable, when disconnecting equipment from an electricsocket.If your equipment uses an AC adapter:⏹Use only the Dell provided AC adapter approved for use with this device. Use of another ACadapter may cause a fire or explosion.⏹NOTE: Refer to your system rating label for information on the proper adapter modelapproved for use with your device.⏹Place the AC adapter in a ventilated area, such as a desk top or on the floor, when you useit to run the computer or to charge the battery. Do not cover the AC adapter with papers orother items that will reduce cooling; also, do not use the AC adapter inside a carrying case.⏹The AC adapter may become hot during normal operation of your computer. Use care whenhandling the adapter during or immediately after operation.⏹It is recommended that you lay the adapter on the floor or desk so that the green light isvisible. This will alert you if the adapter should accidentally go off due to external effects. Iffor any reason the green light goes off, disconnect the AC power cord from the wall for aperiod of ten seconds, and then reconnect the power cord.⏹Japan Only: Use only the Dell-provided AC power cable with the AC adapter.
