I have a couple of 140-180 LoBo with a burned part under the power supply socket:

Is there any solution to fix them, soldering the burnt fuse or whatever?

I was initially gonna say this is the common and typical PowerBook 1XX blown fuse issue, but that don't look like a fuse, nor is it in the same place as the fuses I've replaced.
My electronic ignorance rears its ugly head right about now. Anyone know what the heck is a "D" part, as in "D16"? Sorry I'm not much help . . .

Surface mount diode.
Likely there for protection against reverse voltage. Possibly someone tried a non-apple AC adapter that had reversed polarity.
Providing nothing else is cooked, if you can find the diode's part number, perhaps from a working 140/180, you should be able to order an equivalent from Digi-Key or similar.
Er...what can I remember about those models...7 volts, around 1.2 amps? Anything you can find matching approx. those values should work.
If you get a replacement, make sure the silver line is oriented the same way as the original
thanks! as soon as I can, I go to an electric stuff shop and let you know,
