I have a HP Pavilion dv5-123dx. I am using Windows 8.1. HP sent an update and I selected updste and restart to do it. My laptop didn't restart and locked up. I now have a black screen and no way to get into my laptop. It does connect to the internet, the wireless insignia turns blue, the fans come on and the the power button just blinks . When I shut it off then turn it back on, the same result. I have not been able to use that feature since I put 8.1 in. I have to manually shut it off then manually turn it on.
