Troubleshooting cautions
•
Before deciding to install a new motherboard, consult
•
Inspect all cables and internal components as described on pages
“Checking external connections”
“Checking internal components”
•
If troubleshooting strategies (checking cables and connections, reinstalling system software, and so forth) do not
solve the problem, and you suspect that the hard disk drive or the motherboard is faulty, always troubleshoot in the
following order.
•
First,
replace the hard disk drive and install system software.
Always replace a faulty hard disk drive with a new hard disk drive. Transferring a hard disk drive from one E-46A
to another is incorrect and strongly discouraged.
•
If the problem persists,
reinstall the original hard disk drive in the system, and then replace the motherboard.
Motherboard cautions
During service, avoid using excessive force and always place the motherboard on a grounded,
non-metallic, static-free surface. Never allow any metal to touch the solder contacts on the
underside of the motherboard, especially beneath the battery socket. Improper handling can short-
circuit and permanently damage the motherboard.
Follow the procedures in this section to replace the motherboard. Failure to follow the instructions
in this section may corrupt the system (not easily repaired in the field) or result in an incomplete
installation.
Troubleshooting in the wrong order will cause the system to malfunction. In general, it is highly
unlikely that both the hard disk drive and the motherboard are defective; therefore, avoid replacing
both to solve one problem.
If you have exhausted all other troubleshooting remedies and determined that you need to install a
new motherboard, be sure to observe the following cautions:
