this computer. ? your ac adapter may be designed for international travel but it still requires a steady, uninterrupted power supply. if you ar e unsure of your local power specifications, consult your service representative or local power company. ? the power adapter may have either a 2-prong or a 3-prong grounded plug. the third prong is an important safety feature; do not defeat its purpose. if you do not have access to a compatible outlet, have a qualified electrician install one. ? when you want to unplug the power cord, be sure to disconnect it by the plug head, not by its wire. ? make sure the socket and any extension cord(s) you use can support the total current load of all the connected devices. ? before cleaning the computer, make sure it is disconnected from any external power supplies. use only approved brands of peripherals. unplug the power cord before attaching peripheral devices. do not plug in the power cord if you are wet. do not use the power cord if it is broken. do not place heavy objects on the power cord. ? power safety warning before you undertake any upgrade proce- dures, make sure that you have turned off the power, and discon- nected all peripherals and cables (including telephone lines and power cord). it is advis- able to also remove your battery in order to prevent accidentally turning the machine on. free datasheet http:/// preface vii preface battery precautions ? only use batteries designed for this computer. the wrong battery type may explode, leak or damage the computer. ? do not continue to use a battery that has been dropped, or that appears damaged (e.g. bent or twis ted) in any way. even if the computer continues to work with a dama ged battery in place, it may cause circuit damage, which may possibly result in fire. ? recharge the batteries using the notebook?s system. incorrect recharging may make the battery explode. ? do not try to repair a battery pack. refer any battery pack repa ir or replacement to your service representative or qualified service personnel. ? keep children away from, and promptly dispose of a damaged batter y. always dispose of batteries carefully. batteries may explo de or leak if exposed to fire, or improperly handled or discarded. ? keep the battery away from metal appliances. ? affix tape to the battery contacts before disposing of the battery. ? do not touch the battery contacts with your hands or metal objects. battery guidelines the following can also apply to any backup batteries you may have. ? if you do not use the battery for an extended period, then remove the ba ttery from the computer for storage. ? before removing the battery for storage charge it to 60% - 70%. ? check stored batteries at least every 3 months and charge them to 60% - 70%. ? battery disposal the product that you have purchased contai ns a rechargeable battery. the battery is recyclable. at the end of its useful life, under var- ious state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. check with your local solid waste officials for details in your area for recycling options or proper disposal. caution danger of explosion if battery is incorrectly replaced. replace only with the same or equivalent type recommended by the manufa cturer. discard used battery according to the manufacturer?s instructions. battery level click the battery icon in the taskbar to see the current batter y level and charge status. a battery that drops below a level o f 10% will not allow the computer to boot up. make sure that any battery that drops below 10% is recharged within one week. free datasheet http:/// preface viii preface related documents you may also need to consult the foll owing manual for addi tional information: user?s manual on cd

this chapter provides step-by-step instructions for disassembling the W370ET series notebook?s parts and subsystems. when it comes to reassembly, reverse the procedures (unless ot herwise indicated). we suggest you completely review any pro cedure before you take the computer apart. procedures such as upgrading/replacing th e ram, optical device and hard disk ar e included in the user?s manual but are repeated here for your convenience. to make the disassembly process easier each section may have a box in the page margin. in formation contained under the figure # will give a synopsis of th e sequence of procedures involved in th e disassembly procedure. a box with a ? lists the relevant parts you will have after the disasse mbly process is complete. note : the parts listed will be for the dis- assembly procedure listed only, and not any previous disassembly step(s) required. refer to the part list for the previ- ous disassembly procedure. the amount of screws you should be left with will be listed here also. a box with a ? will also provide any possible helpful information. a box with a ? contains warnings. an example of these types of boxes are shown in the sidebar. ? information ? warning free datasheet http:/// disassembly 2 - 2 overview 2.disassembly note : all disassembly procedures assume that the system is turned off , and disconnected from any power supply (the battery is removed too). maintenance tools the following tools are recommende d when working on the notebook pc: ? m3 philips-head screwdriver ? m2.5 philips-head screw driver (magnetized) ? m2 philips-head screwdriver ? small flat-head screwdriver ? pair of needle-nose pliers ? anti-static wrist-strap connections connections within the comput er are one of four types: locking collar sockets for ribbon co nnectors to release these connectors, use a small flat-head screwdriver to gently pry the locking collar aw ay from its base. when replac- ing the connection, make sure th e connector is or iented in the same way. the pin1 side is usually not indicated. pressure sockets for multi-wire connec tors to release this co nnector type, grasp it at its head and gently rock it from side to side as you pull it out. do not pull on the wires themselves. when replacing the connection, do not try to force it. the socket only fits one way. pressure sockets for ribbon connectors to release the se connectors, use a small pair of needle-nose pli- ers to gently lift the connector away from its socket. when re- placing the connection, make sure the connector is oriented in the same way. the pin1 side is usually not indicated. board-to-board or multi-pin sockets to separate the boards, gently rock them from side to side as you pull them apart. if the connec tion is very tight, use a small flat-head screwdriver - use ju st enough force to start. free datasheet http:/// disassembly overview 2 - 3 2.disassembly maintenance precautions the following precautions are a reminder. to avoid personal injury or damage to the computer while performing a re- moval and/or replacement job, take the following precautions: 1. don't drop it . perform your repairs and/or upgrades on a stable su rface. if the computer falls, the case and other components could be damaged. 2. don't overheat it . note the proximity of any heating elements. keep the computer out of direct sunlight. 3. avoid interference . note the proximity of any high capacity transformers, electric motors, and other strong mag- netic fields. these can hinder proper performance and damage components and/or data. you should also monitor the position of magnetized tools (i.e. screwdrivers). 4. keep it dry . this is an electrical appliance. if water or any ot her liquid gets into it, the computer could be badly damaged. 5. be careful with power . avoid accidental shocks, discharges or explosions. ?before removing or servicing any part from the computer, turn the computer off and detach any power supplies. ?when you want to unplug the power cord or any cable/wire, be sure to disconnect it by the plug head. do not pull on the wire. 6. peripherals ? turn off and detach any peripherals. 7. beware of static discharge . ics, such as the cpu and main support chips, are vulnerable to static electricity. before handling any part in the computer, discharge any static electricity inside the computer. when handling a printed circuit board, do not use gloves or other material s which allow static electricity buildup. we suggest that you use an anti-static wrist strap instead. 8. beware of corrosion . as you perform your job, avoid touching an y connector leads. even the cleanest hands pro- duce oils which can attract corrosive elements. 9. keep your work environment clean . tobacco smoke, dust or other air-born particulate matter is often attracted to charged surfaces, reducing performance. 10. keep track of the components . when removing or replacing any part, be careful not to leave small parts, such as screws, loose inside the computer. cleaning do not apply cleaner directly to th e computer, use a soft clean cloth. do not use volatile (petroleum di stillates) or abrasive cleaners on any part of the computer. ? power safety warning before you undertake any upgrade proce- dures, make sure that you have turned off the power, and discon- nected all peripherals and cables (including telephone lines and power cord). it is advis- able to also remove your battery in order to prevent accidentally turning the machine on. free datasheet http:/// disassembly 2 - 4 disassembly steps

primary system memory (ram) the computer has three memory sockets for 204 pin small outline dual in-line (so-dimm) ddr iii (ddr3) type memory modules. the total memory size is automatically detect ed by the post routine once you turn on your computer. note that three so-dimms are only supported by quad-core cpus ; dual-core cpus support two so-dimms maxi- mum. two primary memory sockets are loca ted under component bay cover (the bo ttom case cover), and one secondary memory sockets are located under th e keyboard (not user upgradable) . if you are installing only two ram modules then they should be installed in the primar y memory sockets under the component bay cover. primary system memo ry upgrade process 1. turn off the computer, turn it over and remove the battery ( page 2 - 5 )
