Inspiron 16 7610 Service Manual for computers with three fans

Service Mode allows users to immediately cut off electricity from the computer and conduct repairs without disconnecting the battery cable from the system board.

To enter Service Mode:

1. Shut down your computer and disconnect the AC adapter.
2. Hold <B> key on the keyboard and press the power button for 3 seconds or until the Dell logo appears on the screen.
3. Press any key to continue.
   NOTE If the power adapter has not been disconnected, a message prompting you to remove the AC adapter appears on the screen. Remove the AC adapter and then press any key to continue the Service Mode procedure.

   NOTE The Service Mode procedure automatically skips the following step if the Owner Tag of the computer is not set up in advance by the manufacturer.
4. When the ready-to-proceed message appears on the screen, press any key to proceed. The computer emits three short beeps and shuts down immediately.

   Once the computer shuts down, you may perform the replacement procedures without disconnecting the battery cable from the system board.
