So I got an Apple IIgs from Uniserver - thanks! This is my first ever Apple II system. Now I just need to figure out how the heck this thing works. When I first power it on, there…

That exact symptom occurred with my bootlegged battery and the 5300 this morning: chime off of the battery and then nothing else.  I forget if I tried to soft reboot. Maybe the ci…

Yea, and it even stops it from powering up sometimes. it will chime and stay black screen, or not chime at all. Or repeatedly chime.  So i tossed it. it was garbage anyway. 

Oh, I meant on the efficiency/persistence, not the crashing on insert - I missed that part of the post.  And I couldn't find anything directly on point to it.

No, its not. failure happened well before any OS ever booted. 

There are software components to the battery's efficiency and longevity; though I don't know that they apply to your two batteries.  Maybe I'm misremembering.  The link I originall…

I had a lombard like that as well, but I ended up getting rid of it. I came into a second one which causes the machine to crash if I put its battery in it, needless to say its dead…

Yeah, I have a Lombard battery like that. Odd thing was that it never worked for most of its existence, and it just somehow randomly started working when I accidentally put Tiger o…

The Kanga power boards are the same and the motherboards are mostly the same.  I'm not 100% sure why those noises but I think it's a capacitor issue.  As you've noted, when you lea…

Btw, I have Kanga too,  witch is almost the same machine. It has that sound problem. Runs and start Ok, but if I leave it plugged on the the power block for a while (like for a ni…

Got about an hour and 10 minutes on its original battery before it died. And it didnt really die, the Energy power management kicked in and put it to sleep.  has a 1997 date code,…

So I'm pretty sure the ADB problem is related to one or maybe two tiny components on the underside of the board just behind the ADB port if moving from the edge of the board.  I th…

All this 3400c talk made me want to pull out mine, and it has its original battery. It is still holding a charge for over an hour of runtime. 

Mouser actually has the holders for just under $6 (534-1109) though they are backordered.  I think for the 3400c battery I'm going to go that route with these:  http://www.ebay.com…

I've cut out the board and made a note of where the wires came from.  There were 4x 26650 lithium cells.  As I can't tab or solder them myself and I don't think the holders I've fo…

Thanks. *)  Yes, it's back to booting for the most part.  Crashes with the card almost like clockwork > Sad Mac. 1)  Cardbus:  Yea I worded a lot of that unhelpfully I'm g…

Also, why the Disk Tools floppy?  Not that that is your problem now, but why not a fresh install of a full system?  NB that when you're installing a system from another machine, y…

There is a RAM card.  But it's only when the Card's inserted that it freezes.  Could some weird PCMCIA issue have screwed up the IDE bus?  [After the first Sad Mac, I subsequently …

The 5300c has a RAM Card in it? Open her up and press down on the cards to make sure they are properly seated. Then check your cabling. What OS is on the Card and on the HD and wh…

Weirdly appears to just be hard drive failure. It's my first sad mac. Sorry for the false alarm [or maybe not, I don't know]. The HD failure is possibly coupled with the 5300 ha…

Also I recapped my power board.  I find no indication it works better than the others.  I think there may be minor issues with the power boards but that mostly the power issues are…

One of these days I'll make it there.
