I have a Dell Inspiron 1545 that is totally dead. It won't power up with the battery inserted nor with the battery removed and just the AC adapter connected. The AC adapter is the original Dell equipment and the blue light on it illuminates when it is plugged into an AC outlet. Gently wiggling the connector right at the power port made no difference at all.
I have tried removing the battery and disconnecting the AC adapter and holding down the power button for over 30 seconds -- no joy.
I have also removed the H/D, the DVD-ROM drive, the battery and all RAM chips. Nothing -- no beeps or anything.
Short of potentially wasting money on a replacement AC adapter that may make no difference, is there anything else I can do to isolate the problem to the AC adapter vs. the motherboard?
Thanks, in advance, for your help.
