How to test battery and power adapter using multimeter?
Replaced DC-in and DC-to-DC boards. Have new battery and new power adapter. Powerbook will not start.
It could be the new (cheap) adapter malfunctions. Last time I tried testing one, I discovered the circular metal thing on the outside is just a shield, whose purpose is to make poking multimeter probes at the tiny separated sections of the male pin about impossible without arcing! So, how can I test the adapter with a meter?
It could be the battery. I don't know whether they ship charged at all. Maybe my old one is fine! They have a connector with six conducting slots. I don't want to damage the battery or my meter. How do I test the batteries with a meter?
It could be I messed something up installing those boards, or maybe another part is faulty. I've already spent too much on these pieces! If the adapter or battery is faulty I can exchange them. If they're both fine, I'll dismantle the laptop to check my previous repairs for damage. Or I'll give up!
Esta é uma boa pergunta?
