HP external wireless keyboard function keys don't work as expected, function lock...?
When using an external HP wireless keyboard you may find that the function keys don't work as expected - for example pressing F5 doesn't refresh the current browser window. Unlike the HP keyboard integrated into the laptop (where you hold the FN key and tap the FN Lock key to turn function lock on and off) the exteral keyboards. Where, like me, you've probably flipped this instead of the off switch and not realised it :) Here is the source documentation manual. http://h10032.www1.hp.com/ctg/Manual/c05575426
