Hello! I have been having this weird problem for a very long time and today I had it so I am seeking help. Sometimes, when I start my computer (which is done very normally and quickly) and I start using Windows, the screen will go blank after a minute or two, sometimes 15 or more. I just work, and blank it goes. It is not related to what software I am using, to how long the computer have been on or the moon phase. In 2 years, I have yet to find a single correlating reason that might cause it. What do I do when it happens? I use the sleep button on the keyboard to put it to sleep and when I wake it up it's normal again. But it quickly goes blank, after 10sec to 2 min. This can go on for 30 minutes sometimes and it just stops by itself. I've discovered that when it finally stops, it usually won't come back if I leaver the computer on. But this today, as an example, after working 8h straight yesterday without problem and leaving the machine on overnight, it started again, and has been going on for 30 minutes now, as I write this post... which is taking very long... Any body experienced anything similar in their life? What in the world could be causing this? FOr now, I will try using another same model screen we have in the office and test it out for a couple weeks... Thanks for any help!
