Dell Inspiron 13 Series 7000 Upgrade problem

Hello,
I just updated the bios on my Dell Inspiron 13 7000 Series; actually this was the second upgrade one that came and I installed in two days. When the computer goes to sleep and it won't come on. When I push the ON button, the screen turns grey and flashes for about 45 seconds. The screen goes dark. When I hit the space bar, the computer opens to the log in screen (password needed).
Thank you.
