I have a relatively new star4, and I've recently been experiencing a problem where it won't wake properly from sleep. It's not all the time, and it's not always under the same conditions, but I've noticed it most often when I've let it fall asleep open.
What's strange is, it seems like it wakes up, but the screen doesn't turn on. I can hear the fan going, and the blue power light is on, but the screen stays off. I tried fn-f2 and fn-f7, but neither works. Sometimes, if I shut it and wait a minute and then open it, it will start as normal. Other times, it won't (like when it was shut to begin with). Any thoughts?
