I'm kicking myself for uppgrading the BIOS from A05 -> A06 two days ago! 
Ever since the upgrade, when I boot the laptop everything goes smoothly till I get to the login screen [ I set it up to require user name and pwd ..aka the ctrl+alt+del login feature .. ] ... and the screen goes blank.. I don't get the login screen and have to power off and re-start..
Upon a restart, sometimes it'll boot up fine, other times I have to restart again..
Before I call Tech Support, is there anyone else facing similar issues since the upgrade ? Or, would anyone happen to know what may have happened..
I did a ' Safe Mode ' boot and it booted up fine.. but I only did that once so..
Also, ever so often when I plug in the AC Adapter to charge the down battery [system is on] the computer just freezes!!
And, once again, I have to hold down the power button and re-start
Any insight would be helpful before I bang my head with Dell's Techies over the phone..
Thanks!
