+ 0 Votes When you say 'mouse' you mean the trackpoint, or an actual mouse? robo_dev 2 years ago What OS? (Windows XP?) You say the keyboard works in BIOS....did you do an actual Diagnostic test on the keyboard and touchpad? This would validate that it's not a hardware issue. Does external keyboard have the same issues? Note that some laptops have 'extra keys' that do special things....but you need to load a special application and/or driver to make these work for some units. Did anybody change the language? French keyboard is different, for example. Since many viruses do keystroke logging, I would wonder if this is a virus that is the main problem if the hardware checks out OK.
