60 Maintaining and Troubleshooting Your E-4200 System
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.
Replacing the power supply
Please observe the following instructions for removing the power supply
and installing a new one
1.
Turn off the system and unplug the power cord.
2.
Open the case, as described in Chapter 1. Observe the “Static
electricity precautions” on page 2.
