Will I harm my laptop with this AC-adapter?

Hello Guys,
I got an old laptop Compaq 6910p but it seems like I have lost the AC-adapter.

However I found a much bigger adapter to another laptop, the size is at least twice bigger. But the socket in the Compaq and the plug do fit.

I have not dared to pug it into the wall yet. But if the plug fit does that mean that the gadgets should be compatible?

What do you think guys do I risk to harm my old Compaq, it is the last computer with a CD-reader I got.

Best regards
Fredrik
