Grounding the Work Area To prevent sta tic damage at the work area, us e the following precautions : ● Cover the work surface with appr oved static-dissipa tive material. Provide a wrist strap connected to the work surface and properly grou nded tools and equ ipment.
Operating Guidelines To prevent ov erheating and to help p rolong the life of the computer: ● Keep the computer away from excessive mo isture , dire ct sunlight, and extremes of heat a nd cold. ● Operate the computer on a sturdy, level surfac e. Leave a 10.
To clean the co mputer case, follow th e procedures described below: ● To remove light sta ins or dirt, use plain water with a clean, lint-free cloth or swab. ● For stronger stains, use a mild dishwashing liq uid diluted with water. Rinse we ll by wiping it with a cloth or swab dampen ed with clear water.
Cleaning the Mouse Before cleanin g the mouse, ensure that the power to the compu ter is turned off. ● Clean the mouse ball by first removing the retaining plate and the ball from the ho using. Pull out any debris from th e ball socket and wipe the ball with a clean, dry cloth befo re reassembly.
Cables and Connectors Most cables used throu ghout the unit are flat, fl exible cables. Th ese cables must be handled with care to avoid damage. Apply onl y the tension required to sea t or unseat the cables during insertion or removal from the conne ctor.
SATA Hard Drives Serial ATA Hard Drive Characteristics Number of pins/conductors in data cable 7/7 Number of pins in power cable 15 Maximum data cable length 39.37 in (100 cm) Data interface voltage differential 400-700 mV Drive voltages 3.3 V, 5 V, 12 V Jumpers for configuring drive N/A Data transfer rate 3.
● Some flat ribbon cables come prefolded . Neve r change the folds on the se cables. ● Do not bend an y cable sharply. A sharp bend can br eak the interna l wires. ● Never bend a SATA data cable ti ghter than a 30 mm (1 .18 in) radius. ● Never crease a SATA data cable.
6 Removal and Replacement Procedures Convertible Minitower (CMT) Chassis Adherence to the p rocedures and pr ecautions de scribed in this chapt er is essential fo r proper servic e. After completing all necessary removal and replacemen t procedures, run the Diagnostics utility to verify that all compo nents operate properly.
Access Panel Description Spare part num ber Access panel 646819-001 1. Prepare the compu ter for disassembly ( Preparation for Disassembly on page 75 ) 2.
