Default Screen Issues - 02-01-2010, 06:55 AM

This dell mini 9 ( is having this weird screen issue where it's screen would randomly grey out on me. A temporary fix for it is to just turn off the computer for a few hours and then turning it back on. I don't know what is causing the issue. My initial guess is a faulty monitor, but since it resets itself after a few hours so i've ruled the monitor itself okay. I checked the connections for a loose cable inside and everything looked fine. My next guess is heat from the computer is affecting the connectors. Any guesses to a solution to this problem?

Is the computer dead during the glitch? Can you see it over the network? If not, you might need a new motherboard, since I'd suspect the graphics chip.

If the Mini is still running normally, just with a glitchy screen, I think it's probably a broken connector/cable between the motherboard and screen, but the screen itself could be broken. I don't think there's much you can do without spare parts to try. You could try disconnecting and reconnecting the cables, but they're very delicate and it's easy to make the problem worse.

Good luck.

On mine I occasionally get what I call a "white screen", which goes away when I knock on the thing.
I have no idea what makes it happen, but a good knock makes it go away every time.

It's one of the things that made me buy a backup Mini 9 actually.

Best way to diagnose this type of screen fault would be to use an external monitor and use it dual screen mode enabling both screens with the same desktop. If the screen goes funny but the output to the external monitor still works fine you can take a good guess its the screen at fault. If both screens output the same then its likely the graphics chips.

The graphics chip will have some kind of cooling likely off of the bottom metal plate under the keyboard so might be worth splitting the laptop in 2 and checking you have a good contact for cooling???

This type of fault wouldnt indicate a loose cable IMO, its very rare for faults like this to be down to cables unless it does it everytime you move the screen, its more likely a componant heating up\dry joint on circuitry causing the intermitant fault.

Thanks for the input. I haven't used the computer in a while, but I'll pull it out soon and try what you've mentioned.

If it is a heating issue with the graphics chip, what's a quick fix for the problem? I haven't had such hardware issues before, but my (uneducated) guess would be to apply some cooling or thermal gel on the chip. Is this smart or stupid of me to try?
