Safety Notices (Multi-lingual Translations) In this manual, safety notices appear in English with a page number reference to the appropriate multi-lingual, translated safety notice found in this section. The following safety notices are provided in English, French, German, Italian, and Spanish languages. Safety Notice 1 Before the computer is powered-on after FRU replacement, make sure all screws, springs, or other small parts are in place and are not left loose inside the computer.
Safety Notice 2 The battery pack contains small amounts of harmful substances. Do not disassemble it, throw it into fire or water, or short-circuit it. Dispose of the battery as required by local ordinances or regulations. Use only the battery in the appropriate parts listing when replacing the battery pack. Use of an incorrect battery can result in ignition or explosion of the battery. La batterie contient du nickel. Ne la démontez pas, ne l'exposez ni au feu ni á l'eau. Ne la mettez pas en courtcircuit.
Safety Notice 3 If the LCD breaks and the fluid from inside the LCD gets into your eyes or on your hands, immediately wash the affected areas with water for at least 15 minutes. Seek medical care if any symptoms from the fluid are present after washing. Si le panneau d'aftichage à cristaux liquides se brise et que vous recevez dans les yeux ou sur les mains une partie du fluide, rincez-les abondamment pendant au moins quinze minutes. Consultez un médecin si des symptômes persistent apres le lavage.
Safety Notice 5 Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel. Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la mise à la masse d'une batterie peut produire suffisamment de courant pour brûler des matériaux combustibles ou causer des brûlures corporelles graves.
Safety Information The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer. General Safety Follow these rules to ensure general safety: • • • • • • • • • Observe good housekeeping in the area of the machines during and after maintenance. When lifting any heavy object: 1. Ensure you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force.
Electrical Safety Observe the following rules when working on electrical equipment. Important Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.
• • • • • • Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check that it has been poweredoff. Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.
The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected. Checklist: 1. 2. 3. 4. 5. 6. 7. 8. Check exterior covers for damage (loose, broken, or sharp edges). Power-off the computer. Disconnect the power cord. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground. b.
Handling Electrostatic Discharge-Sensitive Devices Any computer part containing transistors or integrated circuits (Ics) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge. Notes 1. Use product-specific ESD procedures when they exceed the requirements noted here.
WorkPad z50 Mobile Companion (2608) Read This First Before you go to the checkout guide, be sure to read this section. Important • • • • • Only certified trained personnel should service the computer. Read FRU service procedures before replacing any FRUs. Replace FRUs only for the correct model. When you replace the FRU, make sure the model of the machine and FRU part number are correct by referring to the parts list. FRUs should not be replaced because of a single, unreproducible failure.
Screw Tightening Information Loose screws can cause reliability problems. The IBM WorkPad z50 addresses this problem with nylon coated screws. Tighten screws as follows: Plastic to Plastic Turn an additional 90 degrees after the screw head touches the surface of the plastic part. 90 Degrees More Plastic Logic card to Plastic Turn an additional 180 degrees after the screw head touches the surface of the logic card.
Attention Pushing the WorkPad z50’s Power button will power on (or resume) the system, or put the system in suspend mode: there is no power-off state. If the AC Adapter, battery pack, and backup battery are removed, the system is reset and all the stored data is lost. There is no lithium battery to retain memory while these power sources are removed.
The following symptoms might indicate damage caused by non warranted activities: Missing parts may be a symptom of unauthorized service or modification. Attention When resetting the system, all programs and stored data other than the operating system will be erased. Any password that is set for testing purposes should be disabled before returning the WorkPad z50 to the customer.
