I have a new Lenovo B575 and so often when I go to log on, it allows me to type in my password but the enter key or clicking the arrow doesn't do anything. It goes nowhere. I can't even do a Control+Alt+Del. I'm always forced to hold down the power button and reboot, which I imagine can't be a good sign. Why would the password screen freeze?

You say it happens so often, does it happen when you power on or does it happen when you come back from it sleeping/hibernating/screensaver? – Raystafarian Feb 11 '12 at 22:19
it happens when i come back from sleeping/hibernating/screensaver – Stacy Feb 11 '12 at 22:47
So it's probably a process that's running. It never happens when you initially boot, that's correct? – Raystafarian Feb 11 '12 at 22:57
