Ensure the Keyboard and mouse are connected to the USB ports nearest the PS2 port on the back of the chassis.

Boot to the BIOS F2 and ensure USB emulation is ON.

If you can't access the bios, reset the BIOS using the Jumper on the motherboard, then USB ports should then work.

I cannot get my keyboard or my mouse to work with my dell computer. what can i do?


Please add more information to get specific assistance. Are these wireless devices? If wired, do they use USB or PS/2 connections.

For wireless devices, try replacing the batteries and resynching to the receiver. (You may want to check putting the receiver in different USB ports.)

For wired devices, disconnect and reconnect. For PS/2 devices, you will need to restart the computer to check if the devices work. For USB devices, try connecting to different USB ports.

Next step, try using a different keyboard and mouse (that work on another computer (stick to USB or PS/2 to match the current pair)). Try a wired set if the problem is with a wireless pair. If those work, continue diagnostics on the wireless keyboard and mouse. Check if the mouse and keyboard work on another computer. If they don't work with another computer, replace them.

If another USB keyboard and mouse pair don't work in any port, your USB ports may have failed. Check if even one port works enough to access the Device Manager. (Start > Control Panel > Hardware and Sound > Device Manager (Win7); similar directions in other versions of Windows) Check for a problem with the drivers (For USB ports, scroll down to the USB drivers and look for a triangle with a yellow exclamation point or red x). Try to update the driver or roll it back. If that doesn't help and one USB port works, a USB hub may solve the problem.

Otherwise if the USB or PS/2 ports do not work with any devices and the driver fix doesn't work, then I'd suspect a problem with the ports on the motherboard. Replace the motherboard/computer.

I hope this helps.

Keyboard & Mouse not inputting..Dell OptiPlex GX280.. OS, XP. Microsoft Wireless Desktop 3000 (keyboard/mouse) new.. Dell boots up and desktop appears, the cursor (arrow head) remains in middle of...


Check that batteries are charged and installed properly.--make sure driver disc is installed if applicable- check instructions as some wireless suites need you to push a small connect button to initialise them . Also try shifting the usb conector into another USB port if it is notm getting reconised.

Computer does not recognize the keyboard,, have windows xp 2002 sp3, and bot the USB keyboard/mouse from crayola. another keyboard that is USB works just fine, so not the port???


Sakar International makes this product.

According to them, your operating system isn't supported, although for the life of me I cannot see why.

Here are the supported operating systems:
System Requirements: --Windows 98SE, ME, 2000, XP or Vista --Mac OS X (10.1 or higher) --One available USB port

Here is the website for the mouse:

And here is the website for the keyboard:
http://www.sakar.com/p-1600.aspx?return=y&txt=crayola&page=0

I'm sorry I couldnt help more. This should be resolveable, but the company has no information on how to resolve it.

USB ports do not work with my XP Dell computer


Did you connect the power to the Port Replicator? The USB may be older in the Targus or the XP Dell. (1.1 older, vs 2.0 newer).

Dell Dimension 3100 e10 ...usb won't work


Does the system respond to boot keys (F2, F12) when the DELL logo appears? If so the problem is with Windows drivers and probably can be resolved by reinstalling or rolling back the drivers, but how? Do you have access to another keyboard? Does the system have PS/2 ports? Do you have access to a PS/2 keyboard or adapter? If boot keys work, you could also choose F8 for Last Known Good Config (XP) or System Restore (Vista).

Have you tried different ports (front if using back or visa-versa)?
Try using just keyboard or mouse to see if one has somehow shorted. Also check the ports for any sign of damage.

Problem with KVM switch and Vista


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.

KVM converter


Buy a usb hub and an usb extension, so that you can have 4 or 6 free usb at the front of your computer, and you can switch devices using usb rather then the mouse converter . Using the converter on mouse and keybord make easier for the plugs to slip out, and usb is better. Note some usb modem and some other device do not support usb hubs, you have to plug them straight into the free computer plug , if you have any.

Keyboard stopped working


you could try getting a USB to PS/2 adapter, if you have a PS/2 port on your computer. if it is a Dell made in that last 2-3 yrs ir probably doesnt have PS/2. its worth a shot tho.
PS/2 ports are usually Green and Purple. if you do have two, you might go to your local Radio Shack and see if they have any. Let me know if it works.
About the driver, there is no driver for the keyboard, except the generic USB keyboard driver in Windows.
If the keyboard is truly dead you might just go buy another one (or trie to get one from Dell, if its under warranty).
