blank screeen

I have had the g73s for a little over a year. A little over a month ago when I either turned my computer off or let the computer go into sleep mode the computer wouldn't light up the screen. This barely happened. Around the same time I had few video crashes that reset and reset back to normal. I know nvidia had recently updated new drivers, so I rolled them back and every thing stopped for a week. Now over the last month and especially the last few days my screen has gone blank many times with out the video card working. When this first started I used to just unplug everything and wait, sometimes worked but then I would have to wait atleast an hour. The method stopped working about a week ago. I looked up on another computer reasons why this could happen and one way mentioned how to fix this if it is a static electricity problem. Which was unplug everything, take the battery out and then hold down the power button for a minute and then put the battery back in, plug in and power up. Apparently this resets the bios? Amazingly this worked right away. But now this is happening all the time starting last week. My question is, is there a way to prevent this? All the info I can give is, I usually have the battery out. and let the pc go into sleep mode, rarely turn it off. But lately I have been going back and forth. The only other thing I can over is I have 2 cats, so I dont know if cat hair is getting stuffed in somewhere and causing problems. This is extremely frustrating and would like it to stop on only a 1 year old asus computer. I feel overall I am going to have more serious problems if i cant prevent this from happening. Any thoughts, ideas, or help? I want to take the covering off and clean it, but I know this will break the warranty and I dont even know if its worth even doing. Another note that may help, I can get a thin knife and get some cat hair out between the joint of the lap top once in a awhile. I cant see this causing the static problem but is there something I can do to prevent this? THanks for any help.

 

Have you tried this on an external monitor to see if it is the GPU not displaying a signal or the LCD not powering on?

When you take the battery and ac adapter out for 30+ seconds, that drains all of the residual power and resets the embedded controller, not the BIOS. This controls low level hardware functions.

It is possible that you have a bad or loose LVDS cable if you have to keep draining the power to get the LCD to turn on.

 

yes i did try an external monitor, and it was a no go. Over the weekend I took out the battery and unplugged it over night. The one day I still had to do the hold button down thing, i do this for 60 seconds. The next day it was fine. And today it had no problem. What suggestions do you have that I should take next? This is the only problem I have had with the lappy other than the touchpad pretty much doesnt work. I use a mouse 90 percent anyways but still it is screwed up. THanks again

 

See if it happens without the battery in the unit, plug AC in and remove the battery before starting up each time.

It sounds like a hardware problem, although hard to pinpoint with the info you've given so far.
