I took the plunge and picked up a a working PowerBook 2400c/180 of Ebay recently. Any tips on what to check, what to do to keep it functioning? Capacitors an issue?

Are they easy to replace or was that sarcasm? I'm thinking the later but I got to ask since that would be great if there was some way to obtain/make replacements.The rubber feet and those in the LCD panel will probably have turned into goop by now too - all easily replaced.

This is great info! I didn't realize they used polymer caps in these. Curious how many of them are electrolytic.As with most PowerBooks, capacitors are generally solid except for a handful of tanks in the power supply section. They usually don't cause problems, especially here on the 2400's charge card since most of them are excellent Sanyo OSCON types rather than the standard electrolytics usually populating most computers. IBM Japan did an excellent job engineering these and sourcing quality components.
This is exactly what one of my Kangas is doing. I’ll let you know if I find a way to make mine boot and hopefully it will help yours too.I think I jinxed myself by starting this thread! I can’t get my “new” 2400 to start up after being on the shelf for three weeks...
I tried resetting the power manger to no avail:
When I plug in a power adapter (tested good on my 1400) I hear a small click sound, pressing the power key does nothing. Pressing the resets but on the back does nothing.
The PRAM battery was removed shortly after I got it but I did have a battery installed that seemed to be holding a charge, I wonder if that failed and did some damage not visibly noticeable? Failed power board? Blown fuse somehow?
I’d greatly appreciate any thoughts or ideas to try :-/
Apologies for resurrecting a really old thread, but I am experiencing this exact issue on my 2400c and I was wondering if you could elaborate a bit more on this before I start tearing the trackpad assembly apart? In particular, any photos would be incredibly helpful but in general what do you recommend for cleaning (qtip + isopropyl alcohol?), is the tape replaceable if it's damaged and what sort of buttons can be used to replace it?The trackpad clicker is always a little loose-feeling. Originally there were some foam pads underneath it to reduce this but they've turned to powder after 20-some years. If it's not working the button assembly itself can be cleaned but it's a touchy job. To clean it, you'll have to disassemble the trackpad, unstick the ribbon cable assembly, carefully peel back the clear tape over the button contacts, remove the flexible metal button from the tape, and clean both the underside of the flexible button and the contact on the ribbon cable base without damaging the tape. Then you'll have to reposition the button atop the base contact and reapply the tape without skewing the button or pressing too hard on it. Alternatively you can replace the button with a different physical button but this involves some soldering and careful selection of a new button/modification of the clicker post to get it to fit properly. To prevent damage to the clicker button once you've repaired it, replace the bumpers on the LCD panel and/or don't close the lid; excessive pressure on the button while the lid is closed is usually what damages the button in the first place.
