Usb keyboard will not work - Sony Playstation 3 (PS3) Console

Try connecting an USB keyboard to your Acer laptop. If the external USB keyboard does not work the the laptop is faulty.
If the USB keyboard works then reseat the laptop's keyboard connector to the motherboard, it may have become loose.

Try the keyboard in the USB port you've been using for your mouse. Just move your mouse to a different USB port. I know, this seems like a "too simple" solution, but USB ports sometime get cranky.
A question I would have would be: have you been using a PS2-type keyboard prior to trying to use the Acer USB one? Sometimes the BIOS needs the item "use USB port for keyboard" turned on.
Good luck!

Unfortunately, this switch has a dedicated port for keyboard that listens for the keyboard keystroke. You MUST plug the keyboard into the dedicated keyboard port on the KVM switch for the hotkeys to work. I recommend putting the mouse that comes with your keyboard to the side, and using another mouse, plugged into the dedicated mouse USB port on the switch. Not the prettiest solution, but some of those mouse/keyboard combos have some funky hardware!

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.

try putting your usb keyboard in another usb slot and see if it works. If not get another USB keyboard and use that. Also make sure other usb deives are working so you know its a keyboard issue and not a usb issue.

What type of keyboard are you using? Is it a PS/2 or USB type of keyboard? If it's a PS/2 keyboard (with round purple connector), you may need to restart the computer after connecting it to the computer. But if it's a USB keyboard, there's no need to restart the computer because USB is just a Plug-n-Play device.

You need to isolate the problem. If you're using a USB keyboard, try connecting the keyboard into different USB port of thecomputer. Or try different computer to see if the keyboard is still functioning or not.

If you got the same problem after pertorming some test, it's better to consult the computer manufacturer for second opinion.

Good luck!

Try using different USB port(s). Use ps2/usb converter if necessary.
Test keyboard on another computer, could be bad especially if usb mouse works ok.

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.

just to clarify, your system works well with USB keyboard but doesn't with PS/2.

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.
