PS/2 port is bad. Instead of using the regular keyboard with the purple end, get one that is USB.

Unlock keyboard


Well you may have a bigger problem than a locked keyboard. If you tried to shut down all your programs and reboot, and if you could reboot as someone else to see if it it a locked keyboard. By rebooting the keyboard should auto unlock however if your using a wireless keyboard (check your batteries), and finally on this machine there is a problem with using USB keyboards, try to unplug the USB keyboard then waiting 10 seconds, then plug it into a different USB port, this will reset the keyboard in some cases, but it may be necessary for you to reload the keyboard driver. Okay you say how do you do that without the keyboard? Well if your mouse is working go to START>PROGRAMS>ACCESSORIES>ACCESSIBILITY>ON-SCREEN KEYBOARD and use your mouse to reload the USB keyboard driver and see if that fixes your problem.
Good luck!

Keyboard stopped working


http://www.ascendtech.us/emachines-kb-0705-ps-2-keyboard-black_i_kbdemkb0705bps2.aspx

Things I see here.
1) The second Keyboard you plugged wasn't any good either.

2) The PS/2 port for your keyboard on your motherboard, isn't any good anymore.
Computer off, plug it into the Mouse PS/2 port, and use a USB mouse.
BIOS will reset the I/O address for that PS/2 port, and set it for the Keyboard, when the computer is turned back on.

You may have to;
A) Turn the computer off
B) Unplug from power.

C) Press the Power On button in, and hold it in for a count of 10 seconds. Let go of the Power On button. Do this same procedure two more times.

What you are doing is draining residual power, clearing CMOS Error Codes, and resetting BIOS back to the factory default settings.

Keyboard plugged in, USB mouse plugged in, plug the computer back into power. WAIT 1 minute, turn the computer on.

Still no?
Motherboard replacement.

You didn't unplug the old Keyboard, WITH the computer on, and plug the new Keyboard in, did you? It isn't a hot-swap device. The computer must be off when unplugging a mouse, or keyboard.

For additional questions please post in a Comment.

When you move and place a new keyboard same brand on your computer what is wrong with keyboard when you cant get it to come on it says keyboard error and the light doesnt come on to tell you the keyboard...


Try the new keyboard in a different computer, to see if the new keyboard is defective.

Try the old keyboard (or a different one) in your computer, to see if the keyboard-port is still functioning correctly.

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


Ensure that keyboard lights are illuminated.

Restart the computer with keyboard connected and try booting into setup to see if the keyboard is recognized by bios, if you can get into the bios, then this is an operating system related issue.

If the keyboard still does not respond even in bios, you may have a damaged PS/2 connector. If this is the case, it can be soldered by a technician or the keyboard can be substituted with a USB keyboard.

Keyboard not found


Is it a ps/2 or a USB keyboard? If its a USB keyboard it may be that the drivers won't load until you actually log into windows. Only fix is to boot with a ps/2 keyboard.

If its a ps/2 keyboard then you are probably plugging it into the mouse port. doublecheck your locations.

Trying to install windows and at the boot screen have my keyboard and mouse plugged in windows doesnt see it.. I tried the USB keyboard and nothing I just recently replaced the MOBO using anti-static wrist...


I have seen this before, and the best answer I can offer you is some Motherboards are better than others when working with usb devices while no OS is in place. I actually tried using usb / to / ps/2 adapters and it still would not recognize the usb keyboard in a couple of instances. I had to get a ps2 keyboard for the installation of windows. After windows was installed I hooked up the usb keyboard and it worked fine. (just speaking from my own personal experience here)

Sorry I do not have a more technical answer for you but I'm almost 99.9 % sure this should work, providing there is no problem with the ps2 keyboard port on the Motherboard. I have never failed to install windows unless there was another hardware based issue of some kind, but never a problem with a known good ps2 keyboard.

Just double check everything is seated properly and try to get into the bios setup, if you cannot use the usb keyboard for this, you can try the usb / ps2 adapter, but if that doesn't work either then use a regular ps2 keyboard. That should work fine, then after setup is complete, windows is installed, then your usb keyboard should work fine.

My mouse stopped working, changed the batteries, reset the link button, started working, went away from the computer and now it isn't working. Tried resetting the link button, nothing is happening.


do you have pets or live with other people with access to the pc?
have you tried rebooting?
sorry if it seems basic, but first things first.

Keyboard doesnt work on my repaired emachine with win xp


Could be a couple of things.

First, try connecting another keyboard using the same type of connection as your keyboard. (PS2, or USB). If that one works in the machine; then it's more then likely that there is a problem with your keyboard.

If it doesn't work, it may be a problem with the system itself or possibly a software problem. To test a keyboard is very simple and this test is integrated in most of the BIOS startup systems today. Simply press more than 7 keys right when you turn your power on to the system. If it beeps after a few seconds of holding or brings up a keyboard error, then the keyboard is communicating with the system. If there's a keyboard error that actually states that there is no keyboard present; then there is a problem.

I hope this helps you narrow it down. If it's not the keyboard itself, and you can't get any keyboards to work, I'd have that shop take another look at what they did.
