Safety information The following section presents safety information with which you need to be familiar before you service a Lenovo 3000 computer. General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance.
Page 18
Safety information 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.
Insulation must not be frayed or worn. 4. Remove the cover. 5. Check for any obvious non-Lenovo 3000 alterations. Use good judgment as to the safety of any non-Lenovo 3000 alterations. 6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.
Safety information Handling devices that are sensitive to electrostatic discharge 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.
Laser compliance statement Some models of Lenovo 3000 computer are equipped from the factory with an optical storage device such as a CD-ROM drive or a DVD-ROM drive. Such devices are also sold separately as options. If one of these drives is installed, it is certified in the U.S.
Page 22
Laser compliance statement A CD-ROM drive, a DVD-ROM drive, or any other storage device installed may contain an embedded Class 3A or Class 3B laser diode. Note the following: DANGER Emits visible and invisible laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam.
