I own Acer Aspire 3820TG and the problem that I am facing with the same is that when I am putting the laptop on "Hibernation" then on resume the display is not running on. It just shows a blank screen and I have to force it to shutdown and restart it to get it working. This happens randomly when laptop resumes from Hibernation. Is there anyone who has faced the same and has an idea about a fix?? I am just running out of ideas. I have asked regarding a fix to some of my friends and most have them have suggested me to stop using the Hibernation but I don’t think doing that it is of any sense. I mean the laptop should work fine with these modes, I have cross check it with other people in my office having the same laptop and they are not having any such issues. I have been trying out to track out the cause of this issue in my case but I have not got any luck yet. Is there any workaround that I can try out here??
