Also, your keyboard should be able to get you into the notebooks BIOS screens. No drivers needed for that. If you can't get into those screens, it's not a driver issue. Personally, I've never seen a keyboard that needed a special driver for basic functions. I'd stop chasing that possibility and make sure to rule out hardware first.
I had spilled something into my keyboard of an Acer Notebook. It was stuck with one letter going constantly. Not realizing that it is no big deal to replace the keyboard, I deleted the software icon for the keyboard, planning to use a keyboard I would attach.... Then I was unable to get that one to work, so I gave up on it. Later, a friend put in a new keyboard for me, be he could not get it to work at all.
I presume that I need to download that portion of the Windows 7 software and then get Acer drivers, but I have had problems finding somewhere to do just this. On the other hand, if there is a better alternative that does not involve non-existent back up points, I would like to read about it.
I really hate that on screen keyboard and generally use our house laptop and would appreciate any suggestions to fis the notebook.. .
