6 PowerBook 100's.... but not one works!
yea, only a couple of volts shouldnt matter much.
But try that with a capxon and see how far you get. lol.
Anyway, i restore vintage/antique electronics, like amps, radios, and TVs from the 40s/50s so i know all about the "capacitor plauge"
and just how they like to EAT transformers and rectifier tubes when they short. LOL. Dont ask me how i know. LOL

Transformers, chassies, and cage are the only parts of mine that are original still. Rebuilt it from the ground up in '96 (Dynaco Stereo-70)
i never replace resistors unless i have to.
I just recap it, and its usually fine from there...

UPDATE.....
Still working on my six laptops and I've got some news.
As you could read two of my PowerBook 100 had some live in it. One is actually
really back from the grave and is booting also from a cold start. I guess that
the capacitors are bad...but they can live for maybe some months.....
Out off all my hard disk only one is working. Last night I was working with
it and to my utter disbelieve after a reboot I had not the plesant smiling macintosh but a
flashing floppy with question mark...
Normally this means: another dead disk.... As a last resort I switched the
SCSI cable to the monterboard and ...YES... the disk worked again...
You can understand that these PowerBooks are not good for my nerves...
I also have to make a confesion. This week I bought my seventh PowerBook 100.
The offer was very tempting. The owner was not asking much for it and promised
to deliver it at home. He also told me that it was working. But in a second
email he told me that he didn't have an adapter anymore. How could be know
that the PowerBook was working without any power? Well....he told:
"It worked when I stored it many years ago". But since he was bringing the machine I
could check for myself. The outcome was good and not good. It booted without
any hair dryer.... but the harddisk was not able to boot. Since it was not to
much money I bought it and decided that I would transfer the only hard disk
that works to this one. I also transfered a modem to this machine.
Thats how far I'm now. I hooked up the PowerBook to my Quadra with the special
cable so that I could see the disk on this machine and made a backup. This
specially for the modem software.
I'm still think what to do with the rest of the SCSI disks. Is there a way to
repair or revive these? Or make one good one out of two broken ones?

They're most likely suffering from "sticksion" as it was called back in the day. The bearings/lubricant/whateveritis inside gooies up over time when not used regularly and causes the drives to be very stubborn when it comes time to start spinning. That's why you have instructions online like:
1) extend the back legs . . .
2) place PowerBook on a hard surface . . .
3) lift the front edge of the PowerBook up between 1.5" & 2" off the surface . . .
. . . and drop the freakin' thing right after powering up. 8-o
. . . used to work like a charm for me, but I had a an upgraded APS HDD (don't remember size or make, though 230MB rings a bell) along with the faster APS modem and a full 8MB of RAM in BabyPB. I moved all those goodies over to another PB100 a while back and started a hack on BabyPB. Just got another PartsBook 100 in the mail today . . .
. . . but the AC Adapter included was for a Duo.
If I can dig up my other adapters I'll to give 'em a whirl! [

I had 4.5gb quantum vikings that seized up on me. I took them apart finding goop that had the heads bound to the platter.
I cleaned up the goop on the platter with a microfiber cloth to free up the spindle and heads, put the drives back together, and they still work even to this day.

Update SCSI disks PowerBook 100
After the advices of Trash80toHP_Mini and techknight I decided to open up my SCSI disks and give it a try to revive them. I could not use them anyway.
I never opened up hard disks so everything was new for me. First of all..what to open. A close review showed that I should remove the sticker about warranty. After 20 years I don't think it would matterb: . Second I had to remove 5 special shaped, so called tork screws on top of the disk. I had to use Tork screw driver 8 on the Conner 40 MB disks and Tork 6 on the 20 MB disks. On the picture you can see where to find them. If you have removed them use a very small normal screw driver to separate the top from the bottem. You can wrigle a little bit in the left or right corner and it will come lose.
If you have opend the disk you will see this inside:
On the picture I have made some marks. I will explain.
To get live back into your disk you first have to inspect if the disk is clean. If not you can use a microfiber to clean. In my case the disks where perfectly clean. The disk is parked on the possition you see on the picture. If it starts it has to go to the edge of the disk. With a old disk this movement doesn't work anymore. It is stuck. Sometimes a smack on the back of the PowerBook works at start up of the spinning of the disk. I my case it is not enough.
What to do?
You should watch carefully when the disk start to spin. If it starts you genly push the slider to the edge of the disk. You can hold your finger on the green area of the slider or use a screw driver to manipulate. In this way you help the disk over a dead point.
In my case I revived 2 disks like that. A 20 MB and a 40 Mb disk. The third, a 40 MB disk, I only opened and pushed the slider to the edge even without connected it to the mother board. Then I connected it and it started up direct!
On the 40 MB disks I added a drop of Teflon spray to lubricate on the spot of the blue arrow. Not sure I usefull but a smooth movement of the small slider is essential.
Now I have I working PowerBook 100 and two sort of working PowerBooks. The last two have to be warm to start.

I must warn you, it is not wise to open a hard disk in an area where there is ANY dust at all. Very few microns of dust could ruin the magnetic heads.
Time will tell if the drives remain working.

ive had luck with my quantum viking 4.5gb SCSI drives this way.
They still work to this day. But your mileage may vary.

In this post you can read that I try to get a working PowerBook 100. Sometimes I succeed, but in 2013 the fact is that they are all dead now...But....
Finally I now have a "real working" Powerbook 100!! Our forum member Uniserver was so friendly to do the caps repair. I picked a working screen and put it together with my last working hard disk, a 40 MB Conner. And it works fine. If the hard disk will fail in the end I will replace it by a Monster SCSI/CF card, but for now the hard disk is working.
So what do I learn from all of this. If your PowerBook is failing, like booting without anything on the screen... RECAP. If your screen is totally yellow or purple..... RECAP.
I didn't recap my LCD screen. That could prove the weak point, but if it fails I will also RECAP this part!
For this weekend it is only with the help of my MacIPgw and can be reached on http://mac.vanegten.com

Congrats on the repair, enjoy the Champagne
hehehehe ....if it wouldn't work now after all these years I would "batise" my Powerbook with it!
Uhhmmmm ....I mean baptize.... like they do with ships....
