It's probably the Samsung LCD that you can also find on these sometimes. Model number should be LT121S4-105 or similar. No caps on that one. See: http://www.macdat.net/macintosh/powerbook/general/powerbooklcdindex.html I should add a note about that to the cap reference page. Edit: nevermind...

At this point, I just can't trust that the Wiki will stay online even if it does someday come back up. Clearly it just isn't a priority, and I can't justify contributing my time to something that is so unreliable.

Is the Portable keyboard mechanical or membrane? If it’s mechanical, you might just have some bad traces, as was the case with my Apple extended keyboard.

The sheath is wired to ground on the stock supply.

Great work! I'll have this one up on macdat sometime soon :)

You got lucky, sweet! Enjoy the 180c. Such a nice laptop once working well!

It's likely going to either be remaining goo, or a bad connection caused by corrosion inside those ribbons. Do you see any black spots inside the ribbons? Don't ultrasonic the cables. Too high risk, I'd worry it would break the bonds on the zebra strips.

Any PowerBook post-1994 uses IDE internally, not SCSI.

Least yellowed one of those I've seen in a while. Nice!

I haven't put a developer note archive up yet but that's a good idea. I'm in the midst of a big new project on the Laptop Portal at the moment (php + sql database backend), but after that's done I'll probably look to do that next.

You mean the capacitors? There’s only one on the 5300ce panel and it doesn’t typically cause any trouble. https://macdat.net/repair/cap_reference/apple/powerbook/5300ce_lcd.jpg

First step is to try reseating everything. Make sure the LCD cable is seated well on both sides (and isn't damaged). If the interconnect cable is damaged, you won't be able to tell visually. Only way to know would be to swap in a spare board or replace the cable yourself. If it chimes then...

If you can find one without tunnel vision, sure :) Good luck with that though - they seem much more likely to have it than the 170 is unfortunately.

Beautiful! The 170 is one of the best PowerBooks out there :)

No need to be rude about it.

I've got a laptop from 1995 with a (very) primitive copper heat pipe, and a few others from years after. Good ones started coming out around 2001/02 though.
