My PS/2 keyboard port is not at all working - Mercury P4VM800M7 Motherboard

Is this a USB or PS/2 keyboard? If it is a PS/2 then the port that is integrated on the board is not working. If it is a USB, try plugging it into another USB port and see if it will work. If it does not work on either port then the ports on the system board are not working. It means u're having some malfunctions on the system board itself.

If it is a USB keyboard and it is that the USB ports integrated on the system board are not working, buy and install a PCI card with USB ports. It should work then.

First rule out drivers
- remove the keyboard driver and instruct windows to reinstall the driver

Next check for hardware issues
1. Plug this keyboard into another PC to see if the same problem persists
2. If the problem does occur it is the keyboard (get a new one if that is the case)
3. If the problem does occur then it is not the keyboard it is the port that u are plugging it into.

IS IT USB?
4. If it is a USB Keyboard, plug it into another USB port
5. If the problem persists on all USB ports on the system board, then the problem is the USB ports only IFF the keyboard works fine on another system in other USB ports

Is it PS/2?
If it is not a USB keyboard and it is a PS/2 board, again, and it works fine on another PC, then you have a defective PS/2 port on the system board.

Solution
Get a PCI card with USB ports and install it. Plug ur keyboard into that.

They may well have blown. You can use a USB keyboard and mouse - cheaper than replacing the mainboard.

Hai,

If your keyboard has PS/2 port you have to purchase PS/2 to USB converter and then attache it to your keyboard. Then in your BIOS you have to confirm whether USB keyboard is available and it is enabled or not. If not you have to enable then your USB keyboard works.

Hello fredbeer,

Besides the obvious checking with your device manager, you can download a port test kit HERE. That will be able to test if it's working. The other thing you can do is switch the keyboard into the mouse port and the mouse into the keyboard port. You should get some errors, if not, one of them will work and the other won't. Hopefully, you'll get the keyboard in the mouse port to work, so you know the port is working. Also, if you have any other PS2 devices that you can test it with.

Good Luck and don't forget to leave a rating based on my solution.

Thanks

Mark

Please check the Fixya repair directory for a list of people who will repair your keyboard port near you.

If you get 'Keyboard Failure' message it can have two reasons.
1) The keyboard is not working properly. You will have to replace it.
2) If your keyboard has a PS/2 jack, the PS/2 keyboard port of your computer is not working. Buy an USB keyboard.
You can take your computer to the store and check which type of new keyboard (PS/2 or USB) works with your computer, before paying for it.

CHECK BIOS TO MAKE SURE IT DID NOT TURN ITSELF OFF WHEN YOU PLUGGED IT INTO THE USB.BIOS MAY HAVE TURNED IT OFF TO PREVENT A CONFLICT.RICHARDM69

Minimal information to go on. Since you didn't specify whether this is a laptop or desktop, I'll respond with the assumption that it's a desktop.

Power off computer.

Install new (known working) keyboard.

If that doesn't correct the problem, your issue is probably with the PS/2 or USB port your keyboard is plugged into.

If you are using a USB keyboard, first try moving it to a different USB port, then booting. If that doesn't help, try a PS/2 keyboard.

If you cannot get a known good (working/new) PS/2 keyboard to work in replacing a PS/2 keyboard, try a USB keyboard.

wireless keyboards and in wireless mouse devices, use the following methods in the order that they appear in.

Method 1: Try different ports loadTOCNode(2, 'moreinformation'); Warning If you have to change a PS/2 connection, shut off the computer, make the changes, and then restart the computer. Do not plug a PS/2 device in the PS/2 port while the computer is running.

To determine whether the problem is related to the ports on the computer, use only the two cables that are included with the wireless desktop receiver, or the single cable that is included with a mouse.
USB keyboard and USB mouse loadTOCNode(3, 'moreinformation'); If the USB cable is currently connected to a USB hub, disconnect the device from the hub, and then connect it to a USB port on the computer. If your device is already connected to a USB port on the computer, try to connect the device to a different USB port if one is available.

Note Only one USB connection to the computer is required, even if your device has two USB plugs. If the problem persists, disconnect other USB devices and connect only the USB plug from the receiver to a USB port on the computer.
PS/2 devices loadTOCNode(3, 'moreinformation'); If your devices are connected to PS/2 ports on the computer, verify that you have the following configurations: • Verify that the USB plug for your mouse is connected to the green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2 port on the computer. The mouse PS/2 port on the computer may also be green. If you are not sure which PS/2 port is the mouse PS/2 port, see the documentation that came with the computer. • Verify that the USB plug for the keyboard is connected to the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard PS/2 port on the computer. The keyboard PS/2 port on the computer may also be purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the documentation that came with the computer.If you have to change your configuration, shut off the computer, make the changes, and then restart the computer. If your mouse or keyboard has both USB and PS/2 connections, try using the other connection.
PS/2 keyboard and USB mouse loadTOCNode(3, 'moreinformation'); Verify that the USB mouse is plugged in a USB port on the computer and that the purple keyboard PS/2 plug is connected to the purple PS/2 port on the computer. If you have to change the PS/2 connection, shut off the computer, make the changes, and then restart the computer.

Method 2: Install fresh batteries loadTOCNode(2, 'moreinformation'); Both the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. If the problem persists, install a fresh set of batteries in the device that you are experiencing problems with.

Method 3: Resynchronize your device to the receiver loadTOCNode(2, 'moreinformation'); To resynchronize the mouse or keyboard to the receiver, follow these steps.

Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put other wireless keyboards and mouse more than six feet away. 1. Press the button on the receiver, and then verify that the light on the receiver starts to blink. 2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen.

Otherwise, go to the next step. 3. Press and release the Connect Channel button on the bottom of your mouse or keyboard. 4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.

Clean the mouse lens loadTOCNode(2, 'moreinformation'); This problem may occur if you are using an optical or laser mouse and the lens on the mouse is dirty. To clean the lens of an optical or laser mouse, follow these steps: 1. Use a dry cloth to clean the bottom surface of the mouse. 2. Check to see whether the mouse functions correctly. 3. If you see dust on the bottom of the mouse, use a can of pressurized de-ionized air to blow away the dust on the lens. 4. Check to see whether the mouse functions correctly. 5. If the pressurized air canister is not available, blow dry air on the lenses by using your mouth one or two times. 6. Check to see whether the mouse functions correctly. 7. If these steps do not resolve the problem, use a cotton bud to clean the lens without scratching it.
