Hello everyone, i have a Toshiba Satellite laptop running Windows 7 Home Premium - 32 bit. I started typing, using my left shift button and all the sudden a box popped up just as i was hitting enter. I briefly saw Filter keys on the title before the window disappeared. After that, my keyboard stopped working! I went into the settings and found that Filter keys had turned itself on. So i turned it off and my keyboard is now working again. Filter keys shouldn't disable your entire keyboard, should only stop repetitious keys from being entered but for some reason it did. Filter Keys - (description in the control panel) "Ignore or slow down brief or repeated keystrokes and adjust keyboard repeat rates. For some reason, Filter Keys default settings, (when filter keys is enabled), disables the keyboard. For one, it says using the right shift key 8 times it will enable, i was using the left. Not a big problem but its still incorrect. However, i do not see anywhere in the settings to where it would disable the entire keyboard. Either that, or its this Toshiba Satellite laptop. For instructions on how to turn off filter keys in case this ever happens to you, read below: 1. Left Click "Start" 2. Left Click "Control Panel" 3. Left Click "Ease of Access" 4. Left Click "Ease of Access Center" 5. Scroll to the bottom of the window 6. Left Click "Make the keyboard easier to use" 7. Un-Check "Filter Keys" 8. Left Click "OK"
