After using a wireless keyboard with my laptop some of the keys are not working properly e.g. if I hit 'o' I get '6', this happens with p,k,l,m as well.
These are only suggestions but 1) change the batteries in the keyboard, 2) clean the transmitter and receiver windows if it is an infrared unit. 3) CAREFULLY!!! remove the back of the keyboard and look at how the key switches are configured. If they are the less expensive plastic sheet printed circuit board and the keys have the little carbon buttons on the bottom that makes contact across the associated PCB traces, try CAREFULLY cleaning the button and trace with a cotton swab moistened with a little rubbing alcohol. DO NOT soak it or scrub it as it doesn't take a lot to damage these parts. If it is a more sophisticated unit using Hall Effect switches, these are magnetic sensors with no moving parts. When you press a key, it passes a small magnet on the bottom of the key past the the sensor activating it sending a signal to the computer as to which key was pressed. If this is the case, hopefully you have something magnetic in your pocket or nearby sending false signals to the sensor. If you are a HAM operator, strong RF radiation can also send false signals. If this is the case, check your radio, coax or any linear amplifiers for RF leakage. If this is NOT the case, again carefully open the back of the keyboard to see if one of the key magnets may have become dislodged, misalligned or if a Hall Effect sensor became misalligned. Last but not least hopefully a sensor has not malfunctioned as they are usually surface mount devices and are next to impossible to replace on a work bench without specialized equipment and rock steady hands. You can put away the 200 watt soldering gun, Tex. :) as they are originally built by robot. If this is the case, replace the keyboard.
