On the bench today is my Mac Portable. I recapped it a while ago and continue to prod at it here and there. Today I’m measuring resistance across certain locations to determine if a new hybrid will be sufficient. #RetroComputing #VintageComputing #VintageApple #Macintosh #MacPortable

Here’s the guide I’m using. It’s from a seller with a different replacement hybrid module than I originally purchased. https://androda.work/mac-portable-hybrid-pre-check/

Mac Portable Hybrid removed. Took a desoldering vac, copper braid, and hot air to get this off the board. Looks like some capacitor electrolyte got under the solder mask of the ground plane but otherwise not bad. #RetroComputing #VintageComputing #VintageApple #MacPortable #Macintosh

Cleaned up the site some and installed a socket. New hybrid installed. This one came from eBay last year (v1.3, apparently 1.4 is now available). #RetroComputing #VintageComputing #VintageMac #VintageApple #MacPortable

The new hybrid didn’t change the Mac Portable behavior. As soon as battery power is applied, there’s still random horizontal and vertical lines on the screen and the speaker crackles. Keyboard presses, no change. #RetroComputing #VintageComputing #VintageMac #VintageApple #MacPortable

New Mac Portable Hybrid installed. Will this one cure this cursed laptop? #RetroComputing #VintageComputing #VintageApple #VintageMac #MacPortable

Nope. More lines on the screen, slightly different than before. Won’t boot. #RetroComputing #VintageComputing #VintageApple #VintageMac #MacPortable

@dillera I replaced the caps several years ago but didn't help. Now I've gone through two different hybrid replacements. A display with an error would be helpful at this point! What error are you getting?
