Safety information

Safety inspection guide

The purpose of this inspection guide is to assist you in identifying potential unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards according to the attachment of non-Lenovo features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock)

Explosive hazards, such as a damaged CRT face or a bulging capacitor

Mechanical hazards, such as loose or missing hardware

To determine whether there are any potential unsafe conditions, use the following checklist at the beginning of every service task. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1.Check exterior covers for damage (loose, broken, or sharp edges).

2.Turn off the computer. Disconnect the power cord.

3.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 the frame ground.

b.The power cord should be the type specified in the parts list.

c.Insulation must not be frayed or worn.

4.Check for cracked or bulging batteries.

5.Remove the cover.

6.Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo alterations.

7.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.

8.Check for worn, frayed, or pinched cables.

9.Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.
