Ciao!
Why do you think that the inductor is bad? is it open? usually it is very hard to measure inductance with a multimeter. It might lead you to think that the component is shorted.
From what I remember, the inductor is part of a DC-DC "Boost"converter circuit, the main chip is a LT1070, looking at its datasheet, it looks like it uses a 150uH axial inductor.
At this point, I did a quick search on RS (a large component supplier in Italy), and I found this: PE-52645NL.
I am not sure that the PE-53082 is a 150uH inductor, in power supply designs, they usually choose a slightly higher inductance value than the one recommended by the datasheet.
Once I get some free time, I will look at Portable Board and I will try to find a similar replacement part.
EDIT: maybe this one or this one are suitable replacements, I found this document that lists all of the models from Pulse
Hi Ferrix have you recapped macintosh portable original ac adapter?Ciao!

Keep it! Asap i'm considering to send you some MB to repairAh, i see.. i have an extra i can send you, maybe i can throw it in a parcel back to you?
Hi Techknightyour meter leads are in the wrong holes!
