4. Disconnect the AC Adapter, remove the hard disk and
diskette drive, and install the charged battery pack;
then check that power is supplied by the battery pack.
If you suspect a power problem, see the appropriate power
supply check in the following list:
“Checking the AC Adapter.”
“Checking Operational Charging” on page 351.
“Checking the Battery Pack” on page 351.
“Checking the Car-Battery Adapter” on page 352.
“Checking the Backup Battery” on page 353.
“Checking the Standby Battery” on page 354.
“Port Replicator Power Overload” on page 358.
Checking the AC Adapter:
You are here
because the computer fails only when the AC Adapter is
used.
If the power problem occurs only when the port
replicator is used, replace the replicator.
If the power-on indicator does not turn on, check the
power cord of the AC Adapter for correct continuity
and installation.
If the operational charge does not work, go to
“Checking Operational Charging” on page 351.
Note: For Model 760CD, 760ED, 760LD, 760ELD, 760XL,
and 760XD, there are two types of adapters. The
procedure for checking both types is the same.
1. Unplug the AC Adapter cable from the computer and
measure the output voltage at the plug of the AC
Adapter cable. See the following figure:

(20 - 10 V)
(16 - 10 V)
If the voltage is correct, make sure the
connection between DC/DC card and system
board is not loose.
