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 did not miss any pins.

•Turn off the system, remove the cover, and 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 the new battery is defective.)

If these procedures fail to correct the problem, contact technical support.

When everything works properly, close the case as described in “Closing the system” on page 7, reconnect the power cord, and turn on the system.
