- What to do When AC Adapter Doesn ?
-
1.Verify that the AC adapter brick is receiving power.
-
• Shut down the computer and unplug the adapter from the system first and then from
the power socket. Wait 5 seconds.
-
Plug the adapter directly into the wall socket, bypassing surge protectors, UPS
units, or extension cords. The adapter LED should produce a steady green light.
-
• If you do not get a green light, try the adapter in another wall outlet in another
room or verify that the first outlet works with a lamp or hairdryer.
-
• You can also isolate the power problem to a bad adapter by swapping it out with
a second adapter - such as one for use with the port replicator.
-
2.If the adapter LED lights, check the computer for bad connections.
-
• Examine the system power socket to be sure it does not have any bent, missing,
or pushed-in pins.
-
• Plug the adapter connector directly into the computer, bypassing surge protectors,
extension cords, etc. Be sure that the adapter connector fits tightly into the computer's
power socket.
-
3.If you have access to another computer like yours, try your adapter on it or its
adapter on your computer.
-
4.If your computer is no longer under warranty and the AC adapter does not respond
to troubleshooting, you may purchase a new AC adapter.
