hi. i owned this laptop for about a year now. then yesterday i flash my bios using the 1.11 version from fujitsu-siemens.com then my del key is not working, so i flashed again with the same version, suddenly my numlock key is not working. therefore now when typing i need to hold down fn key. it seems that 4 keys dies. numscr, pause break, insert prt scr, delete sys rq. which all together, i'm thingking to bring to the fujitsu repair centre. is it my keyboard died? tq ps. i know about fn + numlock. but like i told you noresponding. is it because bad flash or anything? fn +f11 also not working.
