You either have the wrong key or that keyboard is defective. The other issue I run into is the CD/DVD drive has lost it's boot capability. We slide in a new drive to fix that. Some owners won't do that so we have to want for them to season a little longer.
my tecra M2V-S330 was recently repaired and the shop did not install many toshiba utilities. this is causing several problems and one is i cannot boot from cd.
i have tried the F2, F12 and and "0" and "C" keys at POWER-UP. nothing happens with F2 or F12 or 0, (i.e., it keeps booting from hard disk)....but with C the, it stops booting.
also, i have not been able to get to the bios setup or any toshiba console/help
