Troubleshooting the battery installation
If you have problems after installing the new battery, try each of the items 
listed below, replacing the cover and restarting the computer after each try.
•Turn off the system and ensure that all exterior cables are attached 
to the correct connectors and secured.
•Check to be sure that all power switches are on. If the system is 
plugged into a power strip or surge protector, be sure it is turned on 
also.
•Enter the BIOS Setup program and compare the settings on the 
screen with your notes or the system hardware manuals. Correct 
any discrepancies.
•Turn off the system, remove the cover, and verify that all cables 
inside the case are attached securely. Also, make sure that the 
colored cable edges are aligned correctly and that the connectors 
didn’t miss any pins. Disconnect and reconnect the cables, and then 
replace the cover carefully so as not to disturb any cables.
•Turn off the system, remove the cover and, if you have the proper 
test equipment, verify that the new battery has power. (It is 
possible, although highly unlikely, that your new battery is 
defective.)
When everything works properly, close the case as described in Chapter 1, 
reconnect the power cord, and turn on the system.

and installing a new one
1.Turn off the system and unplug the power cord.
