Fuse rating for F9900? any place to take a replacement from?
Got two bad left IO boards: one with a blown charger chip, the other - with at least a blown fuse (F9900 - btw, why there is also R9900 - does it refer to the same smd part or to two different parts?)
I tried to desolder the working fuse from the first board, but ruined it. where do I find a replacement fuse? any suggestions? what was its rating (there was a letter P on top of it, and the fuse of green color)
which circuit was it protecting and how do I tell that the rest of that circuit was working fine?
Is this a good question?

p370 states it's a 3A 0603 Very Fast-Acting Fuse 467 Series...

R9900? (sure its 9900 not 9800?) is a SMD resistor. Those are different parts. What number is your IO board? (should be something with a 820-xxxx number)

yep. 820-2102-A
there are three fuses on that board: F8900 (2A?), F9900 (3A, although it's smaller) and F7902 (also 2A)
does anyone know what is the circuit on that board which is protected by F9900? It seems, the fuse just connects several pins on the connectors and that's it. Am I right?
