PowerBook

Hey, maclover5, about the PowerBook 100!

MacScuzzy Moderator USA 119 Posts	Posted - 22 Nov 2001 : 23:07:32 Hey, maclover5, I think I have a solution to your troubles. I was searching for info on the differences between the StyleWriter I and II, and came across this on a BB: --- Subject: Powerbook 100 power problem Date sent: Sat, 15 Mar 1997 09:24:29 +0000 To: cmpost <classic-post@hitznet.com> From: Cesare Cioni On 3/12/97 11:20 AM Fuzzy Gerdes wrote: I just got a PowerBook 100 for a song. I'm sure the main battery is completely dead, because it will only start up with the AC adapter plugged in. Whenever I do start it up, it says "Battery Reserve Power completely gone - will sleep in 10 seconds to preserve memory." which it then does. My first thought was to replace the backup memory (the 3 lithium batteries) but that doesn't help. I've searched the Tech Info Library and back digests of the Classic Mac mailing list, but I can't find any mention of this problem. I had a similar problem. Even after I got a new battery, it still had problems when connected to the AC adapter. It was the small socket in the computer where the AC plug goes in, whose soldering to the motherboard was "broken" so it made not contact well. I opened it, removed the motherboard and remade the soldering. I was lucky: it worked. P.S. Does anyone know what the switch on the back of the PB that shows the battery connected (to the AC power?) and unconnected is for? when it is "unconnected", ALL batteries are not connected to the computer. This saves their power from slowly draining out if you don't use it for some time. Remember that with this computer you should NEVER let the main battery drain completely. Bye, Cesare --- I hope that helps! Must...get...sleep...now. --I hope you've all had a nice Thanksgiving! Brigadier MacScuzzy 68K Macintosh Liberation Army Total 68K Macs liberated:5

maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 23 Nov 2001 : 03:20:29 Thanks MacScuzzy, i'll try it out on the school holidays. How small are the solder joints? And what are the chances of completely killing the 'Book? Novice solderer here, i'm afraid! Who knows, if i can get it working this way, the QFW68KPB project could be a successful venture!

maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 23 Nov 2001 : 14:43:26 oh yeah. One other thing. Sometimes as i'm using the PowerBook, the screen sometimes goes all white when the machine is running. Should i open up the LCD and check in there for loose connections? Pizzabox LCs RULE!!!!!!!

I don't know how small the joints are, as I said, I just happened to stumble on it by fate. Hmm, fate sure is tricky. ------------- Spring has sprung, fall has fell, winters here and it's colder then usual. Brigadier MacScuzzy 68K Macintosh Liberation Army Total 68K Macs liberated:5

If you're a newbie with a soldering iron don't do it until you try to get Apple to fix it. I'm curious to see if they'll still honor their warranty extension for equipment failure due to defective design. If you had the original power supply supply design with a chipped rim on the connector where it snagged and broke the socket it may be a silver bullet. Apple policy was to do a freebie brick/mobo swap on those DOA 100's. Tekserve did one on mine loooong after the warranty expired and I must have gotten the very last new ones available after Apple liguidated them (price had climbed back up a little, drat!). Anyway, good luck with it, best trackball ever produced Sony did one heck of a job on the features/form factor tradeoffs for that baby... Apple must have designed the brick. JT

maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 17 Jan 2002 : 18:55:56 UPDATE: Well, it didn't work. I took out the logic board, and reheated the solder joints. After letting the solder cool, Dad and I took a multitester to the board, and he could see that there was a little bit of communication between the + and - pins. I put the 'Book back together, started up and... It didn't fix it. It still keeps doing the same thing. Oh well, at least i have a classy looking external 80 meg HD for my LCII, so all's not lost. -------------------------- Pizzabox LCs RULE!!!!!!!

Does PB100 function at all (in any configuration whatsoever) If no, report back ASAP, but don't give up hope quite yet. If it works at all, we need as exact a report of the configurations you've tested and symptoms that you have observed as you can manage. I'll take a chance that your "classy looking external 80 meg HD" is your PB100 in SCSIDM. If it is: 1. Note the position of power cutoff switch (tip of switch up toward screen/lid or down toward bottomplate/table surface) 2. Describe the configuration(s) when PB100 is functional and what functions it will perform. 3. Describe the configuration(s) when PB100 malfunctions and note the symptoms as carefully as you can. 4. Talk to your dad and determine: a. were you measuring pos-neg across the solder joints you fixed. b. were you measuring across the solder joints you fixed and the power & ground traces of the mobo c. were you measuring across pos-neg poles of the connector and the solder joints you fixed and where the probes made contact if you were. d. or were you measuring across pos-neg poles of the connector and the power & ground traces of the mobo. Report back ASAP and I'll dig my 100 and the manuals out of a box....... jt Edited by - Trash80toG-4 on 17 Jan 2002 20:29:43 Edited by - Trash80toG-4 on 17 Jan 2002 20:32:21

You checked the backup batteries? If it works one way I can't figure any reason for it not to work in the other, heck, it should boot up with no battery! jt confused as usual

Actually it isn't at all like any other PB, Sony designed and built it for Apple. Its design is unrelated to the rest of the 1X0 series. Sony included that cutout switch and clear instructions to use it to protect the backup batteries from discharging during long tern storage. It makes sense to me that they must be necessary for something when it's time to boot up again. None of your symptoms make any sense at all, the backup batteries are worth a look, IMHO. jt

Glad I didn't elaborate (for a change) ..well....too much anyway..., reading your clarification reminded me of the recent portable thread at fritter. The portable wouldn't run at all without the main battery installed (one source, unverified), maybe having a stack of three HUGE backup batteries is a Sony fix for that flaw. I'm not aware of any backup battery at all on my duos (knock formica). I have never had a maybe it's tim..... full size PB, what do they have for (or do they have) battery backup? jt

Hmm now that i come back to the topic, i'm thinking.... I have a 3v power adapter adapter. The 100's backup batts are 3 volters. If i rip off the door, and solder a power port onto the batt contacts, and connect the 3v power adapter to that whenever i want to boot up, that should work, as the machine is getting power from the "backup power source", right? -------------------------- Pizzabox LCs RULE!!!!!!!

NOPE!!!!!!! first, never botch up a battery compartment like that! you'd want to build something the size of the (3?) stacked batteries with brass or even strips of metal cut from a tin can on the ends with the wires soldered to those. then you want to hook the wires up to something to give you the same voltage (9v?) as the stack of three(?) batteries of 3(?) volts each connected in series to give you a total of 9 (?) volts at the battery terminals in the PB100. i'm thinking a standard nine volt alkaline cell like the one in the original portable prototype of the 100 might be safe to use, but you want to double check the voltages, the count and the amperages against the real backup batteries before trying. i've been meaning to get new ones and see if this is the problem with BabyPB, but i haven't gotten around to it yet. jt �.
