My computer seems to boot up fine but my monitor says no signal and my keyboard doesnt work

You can try tighten up the cable behind the monitor or disconnect the cables and reconnect. You can try another monitor to see whether the mother board and the cable works. Some settings in BIOS may be changed to use on-board video card (the one embeded on the mother board, which is connected on the ports out of the card slots) on your computer so make sure it is using the graphic card that is connected to the monitor. For keyboard, if may be mechanic issue on port or keys or cables if you will not see anything wrong about the keyboard. You can try to use another USB port if it is an USB keyboard or use a USB/PS2 converter if the PS2 keyboard port is not working. If it is a PS2 keyboard, you can check whether the pins are bent and reconnect it. Sometimes that helps. If it is a wireless keyboard, then you will need to fix the monitor and then maybe fix the driver and stuff. You can remove all objects beneath the keys by putting it upside down and shake it or use a blower.

I have a wireless keyboard and mouse and I can't type anything I changed the batteries and its acting like it has no power, nothing is working on the key board but the mouse is working. Thanks Tate

1) make sure your batteries are inserted correctly
2) make sure when you insert the USB sending unit into a port that the USB port is working
3) press the connect button on the sending unit and also the connect buttons on the bottom of the keyboard and mouse.
3) make sure in the system setup that USB is enabled.

Are the mouse and Keyboard USB varieties? If so, then try plugging in a PS/2 mouse and keyboard and boot the machine up.

When you monitor saying which is no signal this is a monitor port problem. Check your monitor connector if it is properly connceted to the motherboard. That is the only way of monitor saying no signal.

    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.

    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:
