2 Turn off your convertible tablet PC (do not place it in Standby or Hibernate
mode).
3 Close the LCD panel.
4 Disconnect your convertible tablet PC from the optional port replicator
(see “Disconnecting from the port replicator” on page 283).
5 Turn your convertible tablet PC over so the bottom is facing up.

The battery used in this device may present a fire or
chemical burn hazard if mishandled. Do not disassemble,
heat above 212°F (100°C), or incinerate. Dispose of used
