Earlier today, I saw a user attempt to type his password in both Internet Explorer 9 and Chrome. In both browsers, he failed to successfully type it in. After 3 failed attempts, he realized it was due to his caps lock key being pressed. In some cases, a keyboard driver will inform you on screen when you press the caps lock button.
