This 5120 is serial number F3031MKDM59. It has been upgraded from the stock 1MB of memory to 5MB of memory and it has the Apple modem installed, an original Conner hard drive, and the high-density floppy drive.
The logic board was professionally recapped several years ago, so no leaking or bad capacitors. Please see photo 5 for full specifications. I ran the full set of Apple diagnostics on this Portable and it passed them all (see photo 6).
The screen has good contrast and no dead pixels. All the 5120 Portables need good illumination to be readable because there is no backlight, but this one is as good as any of them. Cosmetically there are no chips or cracks in the case and no yellowing (see photos). Best of all, this Portable comes with a recently rebuilt battery.
The Mac Portable was designed so that it must have a good battery to run; the AC charger cannot supply enough current. I know how to rebuild these batteries and have done over a hundred. You'll get the battery, the AC adapter, and a LIND external battery charging stand (see photo 7). The external charging stand is a big plus, because it allows you to keep the battery charged outside the computer. These batteries use sealed lead/acid cells which run down even if not used.
If not charged regularly they will be ruined. I have found that charging the battery about every 4 to 6 months will keep it healthy. Also included in this listing are a set of manuals, tour and demo software, paperwork, and the official Apple Portable carrying bag with luggage tag. Everything comes in an original Apple Mac Portable box with original styrofoam inserts (see last two photos). The serial number on the box does not match the one on the computer, which is not uncommon: Many of these Portables went out of the Apple store in the wrong box.As I said, I've restored a lot of these 5120 Portables. This is the best one I ever came across, which is why it stayed in my collection. I won't have another one later.
