Precision 5560 Service Manual

Removing the base cover

1. Remove the eight screws (M2x3) that secure the base cover to the palm-rest and keyboard assembly.
   CAUTION:Do not pull on or pry the base cover at the side where the hinges are located; doing so may damage the base cover.

   CAUTION:The base cover is preassembled with the audio-daughter board. The pins at the bottom of the base cover are fragile. They ground the antennas and audio-daughter board. Place the base cover on a clean surface to avoid damage to the pins.

   

   NOTE:Ensure to remove the protective rubber cover from audio jack pin before replacing the base cover.
2. Starting from the bottom-left corner, use a plastic scribe to pry the base cover in the direction of the arrows to release the base cover from the palm-rest and keyboard assembly.
3. Grasp the left side and the right side of the base cover and remove the base cover from the palm-rest and keyboard assembly.
   NOTE:The following steps are applicable only if you want to further remove any other component from your computer.

   NOTE:Disconnecting the battery cable, removing the battery, or draining the flea power clears the CMOS and resets the BIOS settings on your computer.

   NOTE:After your computer is reassembled and powered on, it prompts for the Real Time Clock (RTC) reset. When the RTC reset cycle occurs, the computer restarts several times and then an error message is displayed– "Time of day not set". Enter the BIOS when this error appears and set the date and time on your computer to resume normal functionality.
4. Disconnect the battery cable from the system board.
5. Turn your computer over and press the power button for 15 seconds to drain the flea power.
