If memory problems occur intermittently, use the loop
option to repeat the test. When the test detects an error,
an error log is printed on the printer connected to the

Power Systems Checkout
To determine whether a power systems problem is due to
the AC Adapter or the battery pack, do the following:
1. Remove the battery pack.
2. Connect the AC Adapter and check that power is
supplied.
3. Disconnect the AC Adapter and install the charged
battery pack; then check that power is supplied by the
battery pack.
If the problem is due to the AC Adapter, go to
“Checking the AC Adapter”
If the problem is due to the battery pack, go to
“Checking the Battery Pack” on page 534
If the problem is not due to the AC Adapter or battery
pack, go to the following sections:
“Checking the Backup Battery (Nonrechargeable)” on
page 536
“Checking the Standby Battery (Rechargeable)” on
page 537
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 AC Adapter is
used with a port replicator, replace the replicator.
