Keyboard problem I have a 720 that does something very strange. The 2 W S X keys suddenly decided to stop functioning. If you look on the keyboard this is sort of a line of keys. I replaced the backup battery and they started to work again for a few hours then went off again. I have done the full reset i.e. removing backup battery and main battery, for 5 mins but the keys will not work at all now.

pls remove the key board ribbon cable and re seat again

The laptop keyboard will need to be replaced, go to www.ebay.com type make and model of laptop, refine search to keyboard.

I fixed a friends laptop recently different brand than your but exactly the same keys she had to bash them to make them work. My first thought was needed new keyboard. Was running vista messed up a lot so i decided a format and put win7 on and is now working perfect. I know this isnt a great answer but strange its the keys on a totally different brand laptop? Hope you get it sorted could you get back to me when you do and let me know? Im so curious now ....Hey possibly just uninstall the keyboard drivers in device manager reboot and see what happens when the pc reinstalls them? Cheers from Scott

In laptops with a small screen (14,15" ) the keyboard is accordingly smaller than for desktops, and there is no numeric keypads, or arrow pad. So the keys 7,8,9 0, U,I,O,P,J,K,L ,comma, dot, / have a triple function: the primary function, the shifted function, and a third accessed by an FN-Fx key combination. The actual key combination may depend on manufacturer. If that key combination has been activated, the foregoing keys perfom the third function they were designed for..
Read your laptop manual to find out how the Fn- function key works and deactivate the Fn-Fx combination responsible for your keyboard behavior..(this article was posted by k24674)..

or else u r keyboard is likely to b defective or ur ram or the system board..
lightly strike/tap the keypad using ur hand..
if u r a professional, open the keyboard..deep clean all the carbon contacts beneath the keys using Iso-Propyl alcohol..put/stick 'Carbon-Dots' (available in cheap level spare market) as n where necessary..

hope it'll work..
always better to seek professional supervision esp of ur system admin/vendor....

Hold down the "Fn" key and the Press the F11 key or the corresponding F Key that says NumLk on it. The light should go off and all should be back to normal.

This is a warranty cloaim and is not unknown for TomTom GPS. You might want to consider changing it for a more reliable brand

Maybe you accidentally activated the F-Lock.

You have a numeric keypad built into the keyboard, press the function button (FN) followed by the number lock button (num lock). Hope this helps.
