Please log in for more thread options yes I want to know what the battery connections are.
Does it provide a source of 5vdc as well as 14vdc?
I've already established that pin 1 on connector is +14v and pin 7 is
ground. I know there's electronics inside the battery to regulate the
voltage and prevent overchargung so I soldered a direct connection to pin 1
& 7 and connected my ac adapter to it. Laptop booted up and worked fine
every day for about 3 weeks. Then the amber light and a message came on
telling me I should connect the adapter or charge the battery. I assume my
direct connection screwed up the electronics inside the battery as the
adapter was still working ok. Battery never even got warm during time it was
working.
Right now all led's come on for the charge indicator but zero out from the
battery. I just want to get the thing working WITHOUT a battery and was
thinking of maybe a dual? voltage regulated power supply.
