| Powerbook 180c startup problem |
Posted by: Ralphieboy on 2018-05-30 01:30:00
Hi. I am rebuilding a PB180C.
Screen capacitors have been changed.
The machine boats a SCSI2SD, a custom 10Mo Ram expansion card and a new PRam battery. The main battery has a 1 minute autonomy.
However, each time I disconnet and reconnect the main power supply the machine does not want to boot anymore.
I usually have to reset the power manager and/or perform some voodoo tricks with the battery and power supply and reset button.
Can somebody help me with that?

Just guessing I would say the dead main battery is preventing the PRAM battery from being charged.

Unfortunately I don’t think so.
The main battery is not actually dead, it holds little charge (1 minute, maybe less).
In fact I kept it in the machine in order to charge the PRAM battery.

I believe the PRAM battery in these PB's won't charge until the main battery is charged to a certain level.

That’s correct and I do believe my PRAM battery is indeed, charged.

I have ordered a brand new (chinese) battery... We will see if this solves the problem.

Hi, My reply is that one minute of battery life is "Dead as a Door Nail", sorry.
