PB 5300 Logic Board transplant advice

Posted by: Bubheart'sDaddy73 on 2020-08-06 21:59:35 Hi, I'm moving my PowerBook 5300 logic board to a separate, small computer case, and would like some advice please. Specifically, the Power Supply Board (part #661-1056) ; it's removable from the main logic board and the battery plugs directly into this. Is it safe to remove this if I no longer intend to use a battery? Or is it required when running the 5300 from mains power too? (It seems like it might be). It would be useful to transplant only the fundamental parts, which is why I'm asking. I'm choosing to move the main logic board and components to a separate case as it suits my setup needs. Because I wear strong specs, the 5300's screen - whilst bigger than some other models - seems too uncomfortably small (my glasses shrink everything by about ⅓). I've recently bought an ADB-USB adapter (Wombat brand) which has a built-in switch to power up the 5300 and it works beautifully. I figure that the 5300 would make a great desktop Mac, now that I have this useful accessory...though it could be viewed as sacrilege by some I guess :/ I've no need for the floppy drive but will be moving the PCMCIA unit too (this is fixed in place anyway isn't it?). Thanks in advance for your help!

No, won't boot without if you are talking about the daughter board. had a couple of issues with a 5300 before, and discovered that capacitors were bad in this board (not allowing the boot process)

Posted by: Bubheart'sDaddy73 on 2020-08-06 23:37:07 I'm not sure if it's classed as the daughter board, the official repair guide says power supply board - maybe they're one and the same thing? Thanks for replying!

Posted by: Bubheart'sDaddy73 on 2020-08-07 03:59:16 That looks the same, yes - I can see the battery connect on the top-right. Is that the daughter board? If so, I'll leave it in situ if the entire system is reliant on it. Thanks!

Posted by: bibilit on 2020-08-07 15:37:36 Yes, a spare with new capacitors around.

Posted by: Bubheart'sDaddy73 on 2020-08-07 18:37:04 Cheers Bibilit, really looking forward to this little project, actually thinking of putting the internals into a small cube case along-side a Socket 478 system (Win 98), so a dual system case. Was never into PC stuff back in the day, always Mac, so it'll be kinda interesting for me.
