Hi forum,

My laptop battery just ran down while the AC adapter was plugged in, and the laptop will no longer charge. I understand this almost always means a faulty AC adapter or a short in the motherboard.

The green light on the AC adapter, which stays on solidly during normal operation, is blinking while the adapter is plugged in. But this green light blinks regardless of whether or not the adapter is connected to the laptop.

Based on what I've read elsewhere, it's suggested that if the problem is a short on the motherboard and not in the adapter, the adapter light will blink when plugged into the laptop but should stay on solid when only plugged into the electrical outlet. Since my adapter light blinks when only connected to the electrical outlet, does this suggest that the problem is likely with the adapter?

Thanks in advance for any help.

In short most likely it is an issue with the ac adapter not only based on the blinking light but also that the laptop's battery will not charge while it is plugged in (the adapter that is). If you like I can try to find a replacement for you all I need are the specs of the laptop so that I can find it. :)

If you have a voltage meter with a DC scale you can take a reading of the output of the adapter to see if the output is correct. The proper output will be listed on the adapter, it will be rated in DC volts.

If you have a meter but don't know how to use it I can provide you with instructions for that as well.
