Laptop with Vista won't go to sleep

Hello Dusan,

Please accept our sincere apologies.
In this case, we'd request you to remove all traces of AVG from your computer using our Clear Tool & reinstall your AVG Internet Security.
After the clean reinstallation, keep monitoring the situation & if the issue persists, please write back to us. We'll check & help you accordingly.

I upgraded from AVG basic to a paid AVG Internet Security (10 device package) today. My Toshiba laptop with Vista now has a problem. When I close the lid the computer won't go to sleep, and when I open it the screen won't come back to life! It's just black. I am forced to hold the power button down until the computer shuts down then I have to power it back up again. 
My other devices work fine.

Please help!!
Regards,
Dusan
