Well, that got your attention!
The key feel is no different. The on-screen, virtual keyboard works fine. My backup USB keyboard and USB number pad work fine.
I run Windows 7 and update regularly. Windows 7 had early problems with PS/2 keyboards. I thought perhaps an update had undone the fix they came up with. This happened the day after an update so I rolled it back. Nada!
I tried updating the driver, but the original driver has never been updated. I reloaded the driver and…Nada.
The computer scans as being malware free.
I bought a new computer (from my smartphone–oh, what a world) yesterday evening (@1910) and paid an extra $4 to have it delivered this morning. Delivery was confirmed at @1010.
I’d still like to use this one as a backup.
Any ideas? The support forums have been useless. [“Save your files and reinstall Windows.” People actually get paid for that kind of advice!]
