Help! My elderly Toshiba Sattelite worked quite fine until yesterday. When I thought it needed a reboot today I was stuck with a mostly dead built in keyboard. I updated drivers ran virus scanner etc. What puzzles me is that a few keys of my QWERTZ board are still working: qüasdgjbn <- are the currently usable leftovers of the entire alphabet. Any ideas what could cause such? - Internal dirt & keyboard's flat cable interaction? Thanks in advance for any kind of advice; I don't have enough USB ports to connect an external board mouse and an external LAN adapter.
