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: v Observe good housekeeping in the area of the machines during and after maintenance.
v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly before returning the machine to the customer. Electrical safety Observe the following rules when working on electrical equipment.
This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide. ThinkPad X20, X21, X22, X23, X24...
Insulation must not be frayed or worn. 4. Remove the cover. 5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM 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.
– Use the round ground-prong of the AC plug on AC-operated computers. Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function.
