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 138. If it is a system board problem, contact the Lenovo Customer Support Center.
