OK. I will make some more pictures.

BIZARRE. From the corner of your photo the PCB layout is different from all the ones I have seen so far. You have a Z8 chip with the EPROM piggybacked.

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.

Look on eBay for a unit with both slots filled. Or make me an offer for mine!

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…

Very carefully. With extra ductape

Bought myself an ATX power unit! Now studying the way to connect it.

Says out of stock but you can email and ask - I'd be pushy.  When I emailed about their 180mhz 3400c main board, they just said out of stock:  http://www.pchub.com/uph/laptop/344-2…

Very rare to find indeed. And I've heard...stuff...about the Newton Sales upgrade, so if I were in the market I'd try to find the Newertech part.

If I recall Newertech made some cards. But I have never seen them. My guess is that these may be a rare thing to find.

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…

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…

raoulduke said: it's only when the Card's inserted that it freezes. Click to expand... So it's back to booting okay now, without the card? Could some weird PCMCIA …
