I use a SONY VAIO laptop VPCS116FA that came pre-installed with Windows 7. I have upgraded to Windows 8. The experience has been good so far but I am facing a frustrating problem. Whenever, I put my computer to sleep, it won't wake up and I have to restart it. Note that this does not affect hibernation which works perfectly fine. However, it is not a perfect alternative to sleep option.
I have tried this method to resolve the problem but in vain: http://www.thulasidas.com/2009-03/blank-screen-after-hibernatesleep.htm
I really am in need for a solution to this problem. Please suggest whatever you think can resolve this.
