Memory Upgrade Compartment Your notebook comes with high speed Double Data Rate 3 Synchronous Dynamic RAM (DDR3 SDRAM). The memory upgrade compartment allows you to expand the systemmemory capacity of your notebook, thus improving overall performance. See "Memory Upgrade Module" on page 68. Under normal circumstances, it should not be necessary to open this compartment. Air Vents The air vents allow air to circulate through the system to cool down the components. TO PROTECT YOUR NOTEBOOK FROM DAMAGE AND TO OPTIMIZE SYSTEM PERFORMANCE, BE SURE TO KEEP ALL AIR VENTS UNOBSTRUCTED, CLEAN, AND CLEAR OF DEBRIS. THIS MAY REQUIRE PERIODIC CLEANING, DEPENDING UPON THE ENVIRONMENT IN WHICH THE SYSTEM IS USED. DO NOT OPERATE THE NOTEBOOK IN AREAS WHERE THE AIR VENTS CAN BE OBSTRUCTED, SUCH AS IN TIGHT ENCLOSURES OR ON SOFT SURFACES LIKE A BED OR CUSHION. Lithium ion Battery Bay The battery bay contains the internal Lithium ion battery. It can be opened for the removal of the battery when stored over a long period of time or for swapping a discharged battery with a charged Lithium ion battery. See "Lithium ion Battery" on page 52. 20 - Locating the Controls and Connectors
