Checking the AC Adapter (TP 600/600E - 2645)
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.
- 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 charging does not work, go to 'Checking Operational Charging'.
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:
| Pin |
Voltage (Vdc) |
| 1 |
+15.5 to +17.0 |
| 2 |
Ground |
If the voltage is not correct, Replace the AC Adapter.
If the voltage is within the range, do the following:
NOTE: An audible noise from the AC Adapter does not always indicate a defect.
