Tough question.

While the right answer is "schematic" you find these are rare.

But about the parts. Did you try digikey.com?

This is why

You replace the boards today. It appears you don't know what the circuit functions are so you can't guess the value. It's pretty rare to see onboard fuses today. I find them in older single board computers but those are very expensive things that came with schematics and service manuals. Over 20K each on average.

Since a fuse is only to protect against, well, I won't write this since you know all that. Why not jump the fuse with the smallest strand of copper wire you have? If the other item was repaired that caused it to blow the laptop will come back to life.

Yesterday i replaced power jack on my laptop and by my mistake with tweezer i remove this fuse ! and i want to replace it its very very small 0.5 mm

Bingo.

If it is indeed a power trace to the jack we can look at the adapter to see what amperage it delivers.

Frankly you may have mis-identified the part. Fuses of this nature are huge or 1210 in size. Sorry but you are in repair so you know this stuff.
