Keyboard wont respond to the pc I tried two different keyboards.what should I do?

maybe they are broken try different keyboard or you need to change the model on control panel of the keyboard you use.

Hi there,

There are a couple of things you can do when your keyboard won't respond. First, go to Start > Control Panel > Device Manager and make sure your keyboard is listed in here. Uninstall it, then reboot the computer. If that doesn't work, goto the manufacturer's website using a USB Keyboard or an on-screen keyboard and reinstall the latest drivers.

That should get your keyboard working again.

Try a different keyboard. If the B key then works, you just have a bad keyboard.

is it a usb keyboard? If so it must be enabled in BIOS. Also if enabled OK, then when at desktop next,, unplug and re-plug into another usb socket and it should be detected and a driver will install, thaat may fix it?

Have you tried a USB keyboard and mouse wired.try also to hook up the normal keyboard and Mouse with out any usb devices hooked on the computer

maybe the devices are both defective or you mistakaly plug it to the wrong ps2 port.check its pin.

Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it to Reset/Connect the mouse to the receiver and work properly.
If not, try pressing the receiver button and then press the mouse. This should be done whenever you change batteries or glitch.
Hope this helps you. Bud

Your computer should recognize a USB keyboard. Go for it.

Minimal information to go on. Since you didn't specify whether this is a laptop or desktop, I'll respond with the assumption that it's a desktop.

Power off computer.

Install new (known working) keyboard.

If that doesn't correct the problem, your issue is probably with the PS/2 or USB port your keyboard is plugged into.

If you are using a USB keyboard, first try moving it to a different USB port, then booting. If that doesn't help, try a PS/2 keyboard.

If you cannot get a known good (working/new) PS/2 keyboard to work in replacing a PS/2 keyboard, try a USB keyboard.

Check for an F Lock key on your keyboard.

By pressing it, it should activate your F Keys and F8 should work as advertised.
