strategy to replacing and servicing FRUs for LENOVO IdeaPad B50

LENOVO IdeaPad B50-70 14.4V 2200mAh laptop battery

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 lenovo 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 LENOVO IdeaPad 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.
