    Oh, wow. You’re very kind. Thank you. And you do have some excellent photos there. It’s actually hard to find good photos like those, especially of a working machine. Most people who shoot photos that I’ve seen keep the screen off, perhaps because the machine is broken. Yes, I am aware and...

    Mac Portable Screen Visibility without Backlight: 5126 vs. 5120

    I'm going to answer my own question with this photo of the backlight diffuser behind the LCD on my M5126 Portable... That textured top makes it diffuse light from the CCFL tube on the left side, but it will also diffuse light hitting the screen when the backlight is off. Because of that, the...

    Thank you so much for your input! I sometimes use ChatGPT as an errand runner because it can search multiple websites faster than I can, but I vet what it tells me. So my spreadsheet is by no means ChatGPT generated. I've spend many, many hours going through old books, newspapers and original...

    @T-Man Can you measure the ball diameter of your PB170's trackball? @David Cook Can you measure the ball diameter of your PB100's trackball? I confirmed today that the Mac Portable uses a 33mm ball. I ask because there's a lot of bad info out there. Even ChatGPT said the ball used in...

    Backlit Portable 5126 — Is your backlight this dim?

    Cracked Hinge on Mac Portable

    Ah yes, Kai! You mean this brilliant fellow... But of course, a 3D CAD genius like him would be need for reproducing the entire subframe assembly. But even if it was reproduced, could it easily be printed in polycarbonate (required for strength)? Even if it could, we still need to figure...

    Cracked Hinge on Mac Portable

    Found photos of another person's broken right-side hinge holder. Poor guy tried and failed with 3 screws! 😯 If we can eliminate these issues by "spring removal," it would absolutely be worth doing. I'm just unsure how do it in a way that won't damage the hinges. 😰

    Cracked Hinge on Mac Portable

    I decided to cut a little triangular-shaped piece from my transparent Polycarbonate resin board to solvent weld over one spot that was cracked originally. It didn't crack all the way through there and was the only location where the hinge holder was still holding on. This weld covers more...

    Backlit Portable 5126 — Is your backlight this dim?

    Folks, Here are more photos of the CCFL tube, end caps, and texture of the diffuser panel behind the LCD... Diameter of the CCFL tube, as measured nearest the end caps (I can expose about 1mm or so of the tube from under the paper covering it, at the ends): Back side of LCD (backlight tube...

    Cracked Hinge on Mac Portable

    Below are photos of mine (before I cleaned out the old grease). What is your technique to removing one of the springs? (And are you able to put them back?)

    Here’s my low power mouse with the small and light ball that’s really terrible and the normal size connector…

    @David Cook I appreciate your photos! Do both of your low-power mice have the long ADB connector, or normal size connector?

    Cracked Hinge on Mac Portable

    I followed your lead and opened my cylindrical hinges, wiped off all visible old grease inside, then dipped one end of a cotton swab in fresh grease and applied that amount. Did you use a lot more grease than that? I use grease sparingly on my floppy drive lubes, but I'm not sure if that's...

    The normal 80mA or so Apple ADB Mice will work on the Portable, but they post a greater battery drain, which is why the low-power model is recommended. But my low-power mouse is the one with the small and lightweight ball which isn't great at all to use. I wonder if they made low power...

    Apple Mice with the "low power circular symbol below" are not common to my collection, as I only have one... And I have no idea why some ADB plugs on mice would need to be longer than the shorter ones. Shorter would seem to be better to keep it plugged in place. But the big question is...

    Backlit Portable 5126 — Is your backlight this dim?

    Understood. Thank you! Quick unrelated question... Starting from 34:46 in your video, your battery is removed and your recapped AC Adapter is connected to the Battery Eliminator but your 5126 wouldn't boot. You then disconnected the AC Adapter's plug from the Battery Eliminator and connected...

    Backlit Portable 5126 — Is your backlight this dim?

    I've seen "photos only" of screens that have very bright backlight. And the color is different too. Mine is dim and rather yellow like you saw earlier in this thread, but the bright ones like the photo below seem bluish... Is that why you've never swapped the stock CCFL tube before? I...

    Cracked Hinge on Mac Portable

    Anyway... As I mentioned in the video I posted about a half hour ago, the little piece of plastic that looks like a latch of some sort actually serves no purpose at all that I can see... Nothing seems to fit inside it. What that means is I could put a clump of JB Weld on the left side...

    Cracked Hinge on Mac Portable

    Holy cow, I just noticed that Jason has a cracked right hinge holder too! Have a close look at his ribs, which are mostly missing in the middle! SOURCE VIDEO What's even more fascinating is that his machine doesn't have any of that chrome paint at all! Wow. Later in that same video, it...

    Thank you both for measuring! The spreadsheet is now perfect, I think!
