I have this weird issue. When I put the computer to sleep by pressing the power button, or using the sleep option in Charms, I can wake it up normally. However, if I close the lid, and later reopen it, all the fans come on, but nothing appears on the screen. I didn't have this issue using Windows 7. Here are my system specs: HP G60-235DX Notebook PC Intel Pentium Dual Core T4200 at 2.00Ghz 3 GBS of RAM Intel Graphics Media Accelerator 4500MHD with 1309MB of video memory Windows 8 Pro 64 bit
