    Lenovo ideapad 120S-11IAP/Lenovo ideapad 120S-14IAP Hardware Maintenance Manual General safety Follow these rules below to ensure general safety: • Observe a good housekeeping in the area where the machines are put during and after the maintenance. • When lifting any heavy object: 1. Make sure that you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift it. 4. Lift it by standing or pushing up with your leg muscles; this action could avoid the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you. • Do not perform any action that causes hazards to the customer, or that makes the machine unsafe.

  • Page 21: Strategy For Replacing A Hard Disk Drive

    Important service information Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: • If you are instructed to replace an FRU, but the replacement does not solve the problem, reinstall the original FRU before you continue. • Some computers have both a processor board and a system board. If you are instructed to replace either of them, and replacing one of them does not solve the problem, reinstall that board, and then replace the other one. • If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs one by one to see if the symptoms change. Replace only the FRU that changed the symptoms. Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.
