System fan error LEDs
When a system fan error LED on the system board is lit, it indicates that the corresponding system fan is
operating too slowly or has failed. To solve the problem, you might need to reinstall or replace the system
fan. See “Replacing a system fan” on page 140. If it is a system board problem, contact the Lenovo
Customer Support Center.
