Keyboard

I have a HP Pavillion 750c computer. My problem is that my computer will not see the keyboard on boot up. It work fine after windows loads but can't use any keys while booting up. Can't look at bios, can't boot in safe mode, nothing that requires a key to be pressed during boot up. Does anybody have any ideas on what might cause this problem.
also if I boot off a floppy drive to the dos mode the keyboard will not work at all. (In dos mode)

 

You will probably need to use a PS/2 keyboard to access the Bios to enable support for the USB keyboard.

 

Thanks. That is what I did and I got in. I checked and the USB was enabled. I guess what I have is a bad keyboard. I am guessing that it has been bad from the get go. When using the keyboard with the ps2 connection I saw thing come up on the screen that I had never seen before. Like F-1 for set up. Never saw that with the usb keyboard. Something is not right with the usb keyboard but no idea what. Works great after boot up. Thanks again

 

Hi Fred,
The computer's BIOS needs to support USB keyboards for you to be able to use them outside of an operating system that has drivers loaded to run them (the BIOS needs to have USB keyboard drivers available). Up until a few years ago, BIOSes did not support USB keyboards, you needed to enter the BIOS settings using a PS/2 keyboard. If you cannot find a setting in the BIOS that allows the USB keyboard to run, you will need to always keep a PS/2 keyboard around to get into the BIOS.

As you are saying, the keyboard will run fine in Windows when the drivers have been loaded.

I was able to get into the bios with a ps2 keyboard and the usb was turned on or enabled. I guess something in my usb keyboard has died. I just doesn't work until it boots up. Thanks

 

USB in the BIOS will the main USB controllers. It needs a specific setting for allowing a USB keyboard to function at startup.

Says here to look for a setting "USB Legacy Support ", note it says "on compatible BIOSes ".

My daughter's computer has USB, but no support for USB keyboards to run at startup. I need to keep a PS/2 keyboard available to enter the BIOS. Your keyboard sounds fine, it is just that the computer's BIOS cannot run it at startup (unless you can find a setting in the BIOS to enable it).

Edit: one other possibility, if you have the keyboard connected through a hub, you would need to connect it directly to the computer's USB port.

I did use a ps2 keyboard and got into the bios. The usb is enabled but still doesn't work. The bios is set so I guess ir falls back on the keyboard.
