all setup attributes that are programmed in the CMOS.
To remove the RTC battery, complete the following steps:
1. Prepare the Notebook for disassembly ( pg 12 ).
2. Remove the Palmrest Cover with TouchPad ( pg 15 ).
3. Remove the keyboard ( pg 18 ).
4. Remove the Heatspreader ( pg 24 ).

piece of material. The RTC battery is located on the system board behind the CD/DVD
drive near the rear edge of the chassis.
To replace the RTC battery, press the battery firmly into the socket and reverse the
previous procedures to replace the remaining components.
