Internal ThinkPad Keyboard
Power on your computer. At the BIOS splash screen, press F1 on your internal keyboard. You should see a message "Entering System Setup." If you are able to enter BIOS, make sure that you can navigate through the menus to ensure basic functionality. While there, press the CapsLk key and ensure that the indicator light turns on or off.
If you are not able to enter BIOS, try pressing the blue ThinkVantage button or press the Enter key.
Boot into your operating system. Click Start, point to All Programs, point to Accessories, and then click Notepad. Using your internal keyboard, press each letter key and each number key to determine if your keystrokes are being recorded properly. If certain keys do not work, make note of these.
Check to see if you have installed any keyboard mapping software that would be interfering with normal keyboard functions.

if its a ps2 kb you prob just killed it by plugging it into a computer with power on. if usb than its ok to do that. if its not lighting up than its dead. get another kb

use PS2 or USB Keyboard & Mouse, maybe it works.. do not rely always on your wireless input devices..

With the limited info that you provided, it seems like the motherboard is not functioning. When you turn the computer on, does anything happen in the box?

Turn off CPU, Unplug Power cable, And all usb devices, let it sit for about 20mins. Plug it all back in. Turn on the CPU! Also make sure if your device requires "DRIVERS" or if you have a CD download and install that before anything.

Hi there.
Keyboards tend to do this from time to time, and is quite common.
You can use a USB keyboard to access your PC until you have a replacement keyboard for the laptop.
If the USB keyboard is not recognized hit F2 (on start up), enter the bios and set it to defaults, save the changes and exit, the computer will restart and you should be able to use a USB keyboard to access your account.

Good luck and thanks for using FixYa!!

try to use another usb connector cable with your psp. It has some lost connection...maybe the data connector is loose. USB has 4 pin(pc side) the voltage supply for power and the data pin..just try.. if it doesnt work...checked if your in admin account because some hardware cant be installed if your not the admin of the pc.

usb doesn't need to be connected to both inputs just try one or the other

Your problem has nothing to do with the Operating System (Vista), it has something to do with the brand of your computer. I have similar problem before, I have Vista (Dell), but the time I connected another Vista (Sony Vaio), everything worked correctly.

This is what you need to do:

1. You have to make sure that you are using a standard USB keyboard and mouse.

2. Connect first the keyboard and mouse directly to the Vista computer to see if the USB ports of your computer are working properly.

3. You may power cycle the KVM switch by disconnecting it from the computers (including the keyboard and mouse) and leave it disconnected for 2 minutes.

4. Reconnect everything after two minutes and then reboot the computers.

5. Try using different USB keyboard if problem exist after power cycling the KVM switch.
