Hi Guys!

I have an old Powerbook 3400c which won't power-up at all. Is there a way to test the external 45watt power adapter using a meter? If this is functioning correctly how might I test the internal power supply board?

Hope you can help ;-)
 
Hmm... I dont know of any meters that can test a power adapter, but I have a way to tell if it works. When you plug it in, the power adapter should get warm and if you put your ear to it, it should make soft a buzzing sound. Hope that helps.
