You should be a little bit more specific. But since you were not, I will try to be more specific about this.

First thing to know is that connecting keyboard and mouse to the computer will always work, no matter what. Meaning that once you connect either one, they will always work. Here are some things to try:

1. Check to make sure that the connector used for the computer is fine, its not broken or bent in the connecter. Check both the computer slot and the connector itself.

2. Make sure that the batteries are new if its wireless.

3. If mouse and keyboard use a separate connectors, and you know that mouse works. Try unplugging the mouse and connecting the keyboard in the same slot.

4. Try a different USB slot in the computer

5. Try a different keyboard all together

6. Make sure there are no off switches on the keyboard that might be in the off position.

I hope this helps.

PS2 Mouse , Keyboard. LPT Printer , Scanner. Have These Problems


If there are PS2 connectors be sure you put the keyboard in the keyboard and the mouse in the mouse socket. There should be symbols next to the connectors. USB connectors will identify themselves so they do not care where they are plugged in.
Printers and scanners not using a USB connector will require that you tell the computer what is there. Using an adapter for USB on the old cables does not mean that the hardware will be recognized.
These issues are identical to those on a desk top PC as far as recognition and setup.
Some older laptops may require the BIOS to be set to use different hardware. The BIOS will have a list of options for internal or external hardware. P4 systems should be fully automated to recognize the items.

I purchased an emachines a few years ago but continued to use the keyboard that I was familiar with. It is now worn. I have installed the new emachines keyboard and nothing happens...no lights come...


Did the old keyboard plug into a PS2 keyboard socket (round purple connector) or into a USB port (flat rectangular connector)? Similarly, what type of connector is the new keyboard?
If it is the round PS2 connector you may have connected into the green PS2 mouse socket instead of the purple keyboard socket. Although the sockets are similar, they work differently.
If it is USB, then try moving it to a different USB port.
Try the keyboard on another PC.
If you cannot get it to work then replacement keyboards are very cheap.

I have a Dell PC and I unplugged the mouse and the keyboard temporarily to clean it. When I plugged them both back into the tower and turned on the computer, neither one worked. I tried to restart, shut...


To try to resolve the issue:
1.) Will a different keyboard and mouse work (PS2 is the name of these connections)
If they will, damage to the keyboard and mouse is likely)
2.) Will a usb mouse and keyboard work?
If they do, then the problem is with the controller on the mobo, unlikley but MAY have been casued by static.

If the USB keyboard and mouse do not work, you have some problems with the motherboard

Try switching off and unplugging the computer, remove the coin shaped BIOS battery and plug in the keyboard and mouse, wait 2 minutes or so and put the battery back, replug in and power on, see if the bios detects the keyboard and mouse (you will see the bios screen flash up a message). If the computer does nOT detect the keyboard and mouse it will (or should) flash a message on the screen saying "no PS2 keyboard or mouse detected".

If this fails to detect the mouse and keyboard and you get no message or beeps, then there may be damage to the connector ports.

If you can get a USB keyboard and mouse to work, use them, Effecting a repair to the motherboard will not be a viable option

Keyboard will not work. I shut off computer and removed mouse and keyboard and turned back on replacing the mouse and then the keyboard. Computer beeps (acknowledging the keyboard) but I can not type?...


If the keyboard is USB, and I am assuming it is, try plugging it into a different USB port and allow a minute for the drivers to install automatically.

If the keyboard is PS2 (round purple connector), make sure you have it plugged in BEFORE you turn the computer on, or it won't work.

If neither of these work, try a different keyboard; if that works, the keyboard needs to go.

Good luck!

USB Keyboard and mouse wont work with PS2 KVM with adapter


Have you tried rebooting once it is connected? Not sure if it makes a difference, but I know you can not hook up PS2 peripherals without rebooting.

How do i connect my PS2 with my PC


on the back of your computer box, you will (probably) find 2 ports that look like this. the PS2 mouse will be plugged into the green colored port. NOTE: PS2 mice (and keyboards) will only fit into the port ONE DIRECTION, so don't force it! make sure to line it up

once plugged in, you will need to reboot your computer, as PS2 can only be recognized while the computer is starting up.

one final note: some of the newest computers DO NOT have PS2 ports. if this is true of your computer, you will need to get a new mouse, or an adapter, like the one shown below:b6b70e7.jpg

Might be a defective keyboard. Check and make sure its compatible for windows vista but all keyboards should work with any system.. As well maybe the port on the computer is bad..
