This is the strangest problem that I have ever run into. The computer is less than 3 years old, the motherboard has been replaced once already. Some of the keys on the keyboard do not work. The keys that do work output in all caps when the caps lock is off and output in lower case when caps lock is on. This is what I have tried already: 1. Uninstall the keyboard and drivers in device manager 2. Scanned for viruses and malware-Negative 3. Tried the battery removal, power cord out press power to discharge the capacitors and still no good. 4. Tried a USB keyboard and a different set of keys don't work. 5. Tried the keyboard on my HTC Thunderbolt while connected using Gmote and even less keys work. 6. Tried a system restore and a clean install of Ubuntu.....Same nonsense. 7. Removed the keyboard from the laptop and re-seated the connector. Now my head hurts! Does anyone have any ideas that I have not tried? I'm thinking it's the motherboard, keyboard controller which means I am not replacing the motherboard in this thing again...UUGGhh... Thank you very much in advance!!
