Hi all,

I have a Dell Inspiron 1545 Laptop. I recently replaced the keyboard because the Right Arrow key had stopped working all together and restores, reinstalls, reseating etc failed to fix it. I didn't realise when I purchased the new keyboard but it has a slightly different layout. So now, even though I am now able to use my Right Arrow key again, the keyboard has different positions for certain functions yet it still responds as if it were the old keyboard. 

For example - To Mute the laptop sound on my old keyboard I would have had to press the "F7" button which doubled up as the Mute button. Mute was the primary function and I would use the "FN" key to use whatever the F7 function was for the program I was using at the time. Brightness could be controlled by the F4 & F5 Keys. The Wireless could be switched on and off by pressing the F2 Key. 

The new keyboard is not laid out like this. In fact, the brightness on the new keyboard is supposed to be controlled by holding down the "FN" key whilst pressing the Up or Down Arrow. However, the computer still responds as if the old keyboard is installed and I have to use F4 and F5 still to control brightness and F7 to mute the machine etc.

I would assume this is something to do with the Keyboard Driver Software. I have searched the internet far and wide but cannot seem to find any Driver Software for the Dell Inspiron Keyboard. I wondered if anybody here had any insight as to how I fix this so that my new keyboard responds in the manner in which it has been designed to respond instead of the manner in which the old keyboard did. It can be quite confusing, especially to other people in the house who aren't as used to the old keyboard layout as I may be.

Any help would be appreciated.
