My computer seems to be stuck in "Stand-by Mode" and will not Wake UP. I have tried re-starting several times, but power light just flashes continuously and computer still will not wake up! Help. 
By restarting, do you mean you turned the power off and did a normal start, or do you mean you've repeatedly tried to wake it up but it won't wake up? In other words, it's stuck in Standby?
If it's stuck in Standby, hold the power switch/button in for 4-6 seconds. It should completely turn off. Then, restart. If this has been or becomes a persistent problem, let us know. You'll need to pursue some troubleshooting steps.
