2 Knowing the Parts Battery Lock The battery is held by a spring lock. The spring loaded latch automatically locks the battery pack when inserted. Holding this in the unlock position will allow battery removal. Usage details are described in the battery section later in this manual. Battery Pack The battery pack is actually combined with the Notebook PC's surface in order to reduce thickness. When the battery is released, the surface and battery pack will be seen as a single unit. The battery pack cannot be further disassembled and must be replaced as a single unit. Mini PCI Compartment Optional expansion cards can be installed in the mini-pci compartment. An optional wireless LAN module enables you to stay connected to your LAN while "roaming" to meeting, conference rooms, or other office locations. Full-time, real-time access to email, Internet, and network resources means not only an expanded office space, but also greater productivity. Air Vents The air vents allow cool air to enter and warm air to exit the Notebook PC. IMPORTANT! Make sure that paper, books, clothing, cables, or other objects do not block any of the air vents or else overheating of the Notebook PC may occur. Hard Disk Drive Compartment The hard disk drive is secured in a compartment. Hard disk drive upgrades are to be done by authorized service centers or dealers only. Audio Speaker (Sub-Woofer) The built-in woofer allows you to enjoy amazing bass (low frequency) sounds in your multimedia applications.
