Ok - while researching a reason to why my laptop keyboard/mouse won't work, I was about to take the keys apart and clean underneath and all parts until I started reading issues in this site. I believe it is possible my keyboard is locked like others. However, I've pressed Fn + F6 then F7 and F8, but have not had success like others in these common threads. When looking at my keys and online manuals I believe the internal controls are a bit different. Plus, I noticed that the mouse "Toggle" switch (tiny button) located at the upper right hand side of the keyboard light stays on. I'm supposed to be able to turn off/on this button, but probably due to keyboard issues, it won't respond. Anyone out there know the trick if there's a different trick to unlocking this model's keyboard?
