Question about Dell PS2 keyboard 04N454

Dell Optiplex 745 series keyboard and mouse (both usb stop working after windows starts)

Dear Xpert (I hope to be one some day),
I was trying to install a wireless elife keyboard and mouse on a Dell system. After it refused to work, I wanted to go back to the original DELL keyboard and mice. Nothing is working! Neither the wireless nor the wired ones are obeying. It's so annoying when you can't even tell the computer what to do! I have discovered, however, that the keyboard (even the wireless) works in the BIOS but is highly sensitive, almost not usable--runs like a cautious rabbit when you even half-press a key!

You've got to help me out ... and soon! Oh, I mean, like YESTERDAY!!!


Thanks,


Dawit

Could try going into windows safe mode and select basic shell. It may then allow you to reconfigure the hardware settings of your system. Presume you have tried another usb port and removed other usb connected devices if they are using same settings ?

SOURCE: Dell Wireless Keyboard stopped responding, please help.

The keyboard should have a button underneath it. Press the button on the usb controller first and then the button on the keyboard. Repeat a few times to see if it connects. If you are still having trouble try another set of batteries as some batteries are not designed for wireless products.

SOURCE: Dell SK-8115 USB keyboard on non Dell PC

This model keyboard has an internal USB hub and Windows only sees the hub when booting. The solution is to get a generic USB keyboard and boot into Windows. Once Windows has loaded the HID drivers for the sk-8115 keyboard then this Dell keyboard will work from then on.

SOURCE: Keyboard stopped working after a Windows update

First thing I would do is get the dell diagnostics disc (hold f12 at start up) and run that, while trying to use the keyboard. (move the arrow keys around and see if they work. you might have to unhook the usb keyboard first) if the keyboard works in the diagnostics area, then its not a hardware issue. (kbd failure would mean no keys worked, or, only some worked sometimes.) You would then need to go into windows device manager and try rolling back the keyboard drivers. If you have full kbd functions outside windows, then you have a windows driver issue. try rolling back, or removing the drivers.

If the mouse and keyboard are wired, try changing the usb connectors around one at a time. If they are wirless and have a usb dongle, try the dongle in different usb plugs.

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.

I hope this helps

KEYBOARD WON'T CONNECT TO PC USB PORT, TRIED 3 DIFFERENT KEYBOARDS. MOUSE CONNECTS FINE


Will the keyboard connect to the port you have the mouse in? The only thing I can think of is that there are bent pins in the USB port on the machine. If it has more than one USB port try another one. If all else fails you can always get a USB hub.

Wireless Optical mouse compatible with Dell


I think every wireless optical mouse is compatible, because an usb receiver comes with the mouse.
Just go to your local store, or a computer webshop and buy one
