Hello,
I tried, to restaurate the battery pack of the Powerbook-3400c.
I exchange the Li-Ion Cell but it looks like the logic board (see attachment) during the exchange of the cell just died.
Was anybody able to resuscitate the board?
The only thing I was able to find out is that if you attached a DC Power Supply 16,8 V at the front contact (more o less simulating the charging) and press the check button of the board, all the 5 LED light up.
Any Idea or experience?
Thank you in advance and best regards

@FABIO this is some progress at least! 🙌 I have a component tester perhaps I can identify dead components, when I get some time I’ll have a check over | Posted by: FABIO on 2022-04-12 03:44:54
