Re: dead mouse port

Good day Godlyman

My keyboard will not work


Keyboard Is Dirty:

Keyboards should be cleaned with "spray-n-wipe" cleaner and a cloth or tissue on a monthly basis. Ensure that computer is not powered up while cleaning the keyboard. Compressed air can also be used to clean between the keyboard keys. Another tip: clean the keys with a cotton swab dipped in alcohol.

"Keyboard Not Found" Message:

Your keyboard is not plugged into the computer securely. Unplug it and plug it back in and the problem should go away. If this doesn't work, follow procedure: "Computer isn't taking inputs from keyboard" (below).

Key Is Stuck:

1. If a key does not work or is stuck in the down position, you may try to remove it with a CPU "chip puller" tool. These simple "L" shaped tools are great at pulling out keys. Once you've pulled out the stuck key, you can try to stretch the spring to "reanimate" its action.

Computer Isn't Taking Inputs From Keyboard

1. Is keyboard connected to computer? Ensure that the keyboard is plugged into the keyboard jack and not into the mouse jack. If the keyboard was unplugged, plug it back in and reboot the computer.

2. If the keyboard still doesn't work on boot-up, power down the computer and try to borrow a friend's known-good keyboard for troubleshooting. Plug the new keyboard up and boot up the computer. If the new keyboard works, the old keyboard is bad and needs to be replaced.

3. If the known-good keyboard doesn't work, check your BIOS to make sure it sees the keyboard. It should say, "installed." If the BIOS recognizes the keyboard, then you probably have a bad keyboard port.

I Plugged Keyboard Into Mouse Port

1. Many mice and keyboards today use a PS/2 connector
. If you plugged your keyboard into the mouse port (or viceversa), follow steps 2 and 3.

2. Shut down the computer and plug the keyboard into the keyboard port. The keyboard port is usually marked with a "keyboard" symbol. Plug the mouse into the mouse port (usually marked with a mouse symbol).

3. Reboot the computer; the keyboard should work now. If keyboard doesn't work, check your BIOS to make sure the BIOS recognizes the keyboard. You should see the words, "installed" or "enabled" under the keyboard.

4. If the BIOS recognizes the keyboard but it still doesn't work, you may have a bad keyboard port.

I Spilled a drink on my keyboard!

1. If you spill any liquid in the keyboard, turn it upside down ASAP. Drain all the water out of the keyboard, shaking it if necessary. If you've spilled water into the keyboard, just let it dry. You may use a hair dryer to dry out area under the keys (remember, too much heat and you could damage the electrical components).

2. If you've spilled a soda into the keyboard, completely rinse it in warm water. No soap please! You may use a hair dryer at this point or just let it dry for 2 days. Ensure the keyboard is perfectly DRY before you attempt to use it again. Don't plug a wet keyboard into electrical equipment. Think safety.

5. If the keyboard still doesn't work, replace the keyboard.

If you can bott the computer normally and don't have to type a password in, then go the control panel and then choose device manager. Scroll down to the mouse and keyboard plus signs and right click on the mouse and keyboard one at a time and select uninstall. When the original mouse and keyboard have been uninstalled, reboot the computer. When Windows starts back up it will be forced to search for the new hardware and will install the drivers for it. If it wants to search for new ones allow it. If you have to type a password, you will have to go and get a usb keyboard that works off one of the usb ports. If this doesn't work, reboot the computer with the Vista disc in. Click any button to boot from the cd. When the windows files load and windows starts, choose repair, choose the windows installation and let windows search for problems and see if it can fix them. If all fails, go to system restore and back the computer up a few days and let system restore fix the problem by taking you back in time a few.

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.

Mouse wont work , I have put new batteries in & have also looked in control panel which says it is working ... Red light is on. HELP...

  • Make sure that the mouse is connected physically to the correct port and that it is not loose.
  • Check the mouse wire to make sure it has not been excessively twisted, bent or damaged in any way.
  • If you have another mouse that you can try in place of this one, try swapping them and see if the problem goes away. Similarly, you might want to try your mouse on another PC and see if it works. (Remember that drivers are often specific to certain types of mice; you want to swap with another mouse of the same type, using the same interface, either serial or PS/2).
  • If this is a new PC, check this section for troubleshooting possible general problems. In particular, there may be a loose or incorrectly connected internal cable to the COM port that you are using for the mouse.
  • If you are using a PS/2 style mouse, make sure it is not connected to the (identically-sized) PS/2 keyboard connector. This of course will also make the keyboard not work properly.
  • If you are using a serial mouse, you may have a problem with the serial port itself. Resource conflicts and other problems with the serial port are fairly common. Look here.
  • If you just upgraded your motherboard and now your mouse is not visible, a likely cause is that you left the old cables that attached from the serial port connectors to the motherboard headers in place. These cables are not universal, and you might now have the wrong kind installed for your new motherboard.
  • If you are using a PS/2-style mouse, remember that the mouse uses IRQ12. In some situations, this may cause a resource conflict with another device. Check here for more on resource conflicts.
  • If you are trying to use a PS/2-style mouse on a serial port, or a serial mouse on a PS/2 port, you must use a so-called "combo" mouse. These are specially designed to be able to handle the different electrical signals that are used by the two different mice. Some mice will fit the adapters physically but will not function correctly because they cannot handle the different signaling levels required;

    1. Check your Keyboard-Video-Mouse (KVM) switch. If the system is connected to a monitor, mouse, and keyboard through a Keyboard-Video-Mouse (KVM) switch, or console selector switch, then disconnect the switch and connect monitor, mouse, and keyboard directly to the system. If this solves the issue, please contact your switch manufacturer for support and compatibility on the switch. Some switches can have a firmware update applied to resolve common problems.

      Note: BladeCenter Telco chassis - The KVM module contains keyboard port, mouse port, Power LED, Location LED, Critical Telco Alarm LED, Major Telco Alarm LED, Minor Telco Alarm LED and a video port. The PS2 keyboard and mouse connectors are standard 6-pin Mini Din. The Telco alarms mirror the Telco alarms located on the front panel of the media tray because they use the same signal lines. The KVM module allows the connection of a VGA monitor for system maintenance and control. The video connector is a standard 15-pin VGA. The KVM module is hot-swappable. It is docked into an edge card connector located on the backplane:


    2. If you have your system daisy chained for KVM capabilities using the C2T port (e.g. xSeries 330),
      then you must flash the C2T firmware after flashing the system BIOS, in order for the mouse and keyboard to work. Otherwise, after a BIOS flash, you will lose keyboard/mouse capabilities unless you walk up to each machine and push the select button.

    • If you are using NetBAY Advanced Connectivity Technology (ACT) CAT5 cabling in your rack server, instead of KVM cabling, click here for ACT information.

    1. Check for POST/startup errors. If you are getting a POST/startup error on the keyboard and/or mouse:

    2. Verify that all items are firmly connected to the correct ports, and that the cables are undamaged with no bent pins. The PS/2 style mouse and keyboard ports look identical, but are not interchangeable. The mouse and keyboard must be attached to the correct ports in order to be recognized by the system and to function correctly.
    3. Swap each item for known good units. If a new item works where the original did not, then the original component must be faulty.

    4. If the keyboard works during the POST/BIOS screens, but not in the operating system, check software logs for device driver errors. Contact your software vendor for more support in configuring the I/O devices.

    5. Check the F1 Setup error logs for system component failures or errors. These are found under Event/Error Logs. Troubleshoot suspect components further to determine if the hardware is faulty. If an IBM component is determined to be faulty, please contact your local IBM Support Center for warranty replacement of the part(s). Please have the Field Replacement Unit (FRU) / Customer Replacement Unit (CRU) part number and Machine Type, model and serial number ready.

    1. Run hardware diagnostics. Replace any parts found defective.

    1. fw.gif
    Download the latest diagnostics for your system
    1. If you can down the system, check the keyboard cable connector on the system unit for proper voltage.

    2. Power off the system.
    3. Disconect the keyboard cable form the system unit.
    4. Power on the system and check the keyboard cable connector on the system unit for the voltages shown:

      PIN Voltage (Vdc) 1 +5.0 2 Not used 3 Ground 4 +5.0 5 +5.0 6 Not used
    5. If the voltages are not correct, replace the system board. Otherwise, replace the keyboard.

    6. If these steps have not solved your problem:

    is your mouse and keyboard plugged into a PS2 connector
    look inside of your case and see if any capacitors are buldging on your motherboard the tops of the capacitors should be level/flat if they're ok, sounds like they are going, look for brown rusty color also around tops of capacitors, might be your outputs are going. If you have your mouse and keyboard plugged into ps2 ports try a USB Mouse and keyboard, borrow one first or buy a usb laser mouse for $12 worth a try even if your ps2 ports are blown, use the usb ports for mouse/keys ;)
