work to allow me to enter the BIOS so it does not seem like the keyboard hardware is at fault, it has to be something with a Windows 8 setting on boot up to the desktop.
Also when doing a cold boot pressing the ESC, F9 etc. I might add that when Windows boots up I am able to type in the user's password so the keyboard does appear to be working until Windows actually goes to the desktop and then nothing works on the keyboard. There must be a rational solution to this problem but it is beyond me. I tried suggested registry changes, nothing seems to work. I have tried deleting the keyboard driver through device manager, re-booting etc. I found numerous sites (the HP forum and other sites) on the Internet encountering a similar problem and none of the so-called solutions I found worked to resolve the problem. i.e., right click and try to rename an Icon or click on Internet Explorer and try to type in a URL the keyboard does not work. but when continuing to boot to the desktop Windows the keyboard is no longer available i.e. I tried reinstalling Windows on the notebook, when booting Windows 8 allowed me to type in the username password etc. Hooking up a USB keyboard did nothing to fix the problem and also did not work. His computer was working just fine and recently the keyboard stopped working. I am trying to help a neighbor sort out a nasty problem.
