You might also consider an open-firmware reset dance. Can't hurt, might help.

Wait a sec... Isn't there a PMU reset button? I also thought that the lappies have a CUDA somewhere, no? Pull the battery and run it off AC. Does the problem happen? How about o…

That is really, really weird.

Sorry to hear about your problems. In all the years I have been using OS 7, 8 and 9 I have never heard of the problem you describe. Hope you get it sorted out soon.

In a way. Here's an issue I've seen with iBooks running OS 9 before: as soon as the desktop loads, the powerbook falls asleep. Wake it up, it falls back asleep. No amount of PRAM r…

The only fixable cause of that symptom is a display cable problem. The flex cable is not infrequently to blame. If squeezing somewhere on the edge of the lid around the display mak…

I hope someone can help me! I have a powerbook 1400 which I use daily, however a short time ago it began having two bars on the right side of the display. These are most noticable…

...I wonder though, whether the 1400 even has the Adapter Sense circuits mentioned. Click to expand... Excellent question. As I write this I have a PB1400 running and charging…

Got it, thanks. I wonder though, whether the 1400 even has the Adapter Sense circuits mentioned.

Note that refers to the Powerbook G4 15" and 17", which I believe take the newer, smaller (but similarly shaped) power connector. So it may not be relevant to a 1400. By "outer se…

There is a somewhat obscure note on PowerBook power adapter sense circuits at http://developer.apple.com/qa/qa2001/qa1266.html which specifies clearly where the +24V and Gnd conne…

Thanks! great info.. i have the charger of my old stolen laptop. it is 24V, I must try the thing about using a 6.5mm plug

Ah, I see, RetroFloppy is the way to go! Thanks, David! Ben

I do not have any Apple equipment other than my iMac. I'm looking for hardware translation service for my old 5.25" floppies (formatted on Apple ][e). Cheers, Ben

Yesterday I installed the Airport extreme card in the iMac. I put it back together correctly and carefully. I booted it and nothing. It would make that spinning hard drive noise an…

Yeah 24 volt is right, just said 9 off the top of my head. I know a charger from a lombard will work though.

The chargers from the Powerbook Duo series will work also. They won't give you enough charge to both run the laptop and charge a flat battery at the same time, but you can do one …

The 'correct' charger is a Macintosh PowerBook 45W Power Adapter, M4896 (1996), 100-240VAC 1.2A in and 24VDC 1.87A out. The M3037 (1995) for a PB 5300 looks similar, and has a si…

I believe its 45 watts 9 volts but i am not completely sure, i know a charger from a lombard will work and i think a charger from a pismo will as well.

hi!.. im waiting my "new" powerbook 1400 what i get free.. but it not have the Charger.. and i dont know if i can get the charger in my city.. so.. anyone knows if i can buy some o…
