Q:SOME OF THE KEYS ON MY KEYBOARD WONT WORK ?
Keyboards will eventually go bye bye. Unfortunately you will have to either live with it or buy a new keyboard. Otherwise you could try air-dusting the keys.
Q:Are there any whammy bars for keyboards?
I don't think there are ones that hook up to an already existing keyboard, but some come with knobs on them that create whammy-bar effects.
Q:Keyboard when starting Windows?
Unplug the usb keyboard from the computer, power the computer down completely and remove the power cord/switch the power switch on the power supply wait 30 seconds plug in power, usb, and try rebooting The usb keyboard should work now, if not, you'll need a different keyboard. USB ports sometimes stay active even when the computer is shut down, so you have to do a cold boot to get them to reactivate themselves on bootup to detect a keyboard. You could try another usb port too.
Q:turn off laptop keyboard?
Turn Off Laptop Keyboard
Q:A question about my Keyboard?
Well, first do what the other posted said, but be careful when assembling it back together as you need to align the sensor part of the keyboard nearly perfectly.
Q:Keyboard problem.?
I think your keyboard is screwed up. My advice would be: Get a new keyboard :P
Q:Help! my keyboard is unresponsive?
Have you tried plugging the keyboard directly to the PC keyboard port and not thru the adapter?I'm assuming the desktop has a P/S2 port. If yes, then it is possible the keyboard is drawing much more power than the USB ports can provide. Try the following: 1. Check to see that all pins in the keyboard connector are straight and none broken 2. Use a different USB adapter If none of these works, you probably have a dead keyboard.
Q:Howto type arabic characters without an Arabic Keyboard?
well you can go to Microsoft word insert symbols
Q:Wireless Keyboard?
Either the batteries in your keyboard are low or there is interference between the keyboard and the receiver. Make sure you follow the instructions that came with it for positioning/distances.
Q:music sites for the keyboard.?
*pokes additional details* No, you did not, but trust me, playing music is soooo much easier then you know how to read it. It really isn't nearly as hard as it looks. Do yourself a favour and pick up a piano book or go to that site that mamianka said. If you choose to continue by just using the notes, then you will be limiting yourself to mary had a little lamb and hot cross buns.
