Then replace the keyboard, and temporarily connect an external one until the replacement internal keyboard arrives.

if the KBD does not work,  + the screen , it looks like you better replace the mother board
you can look if the usb keyboard works - and is enabled from the bios

nobus, yes + the screen does not work and this is the reason I tried to use an external monitor but I was surprised when I saw that even keyboard did not work... But I did not connect this problem with the problem of the screen and I thought that maybe had to do with the VGA for some reason..!!!
So your opinion is that I have to replace  its motherboard (or buy new laptop!)

well  - you can try an external  keyboard and mouse, and see if they do work first (see rindi's suggestion)
you can always test if the screen and keyboard work fine in the bios, or when booted from a live cd  - here a couple :

i prefer using knoppix

from your post i thought the external screen DID work - but not the keyboard
if BOTH do not work, try removing the bios battery for a minute, reconnect and check
and if this does not work - yes a new motherboard for Christmas!

Sorry.... I gave the laptop to a technician and he told me that the screen was the problem... So the solution takes me about 200 euro the screen and 40 euro the work... without taxes... thanks
