OS: Windows 7



I have a Dell N7110 and run Windows 7. My screen fades in and out. At times it seems to be related to doing something with one of the USB ports. But, then it seems to do it on its own. Sometimes it fades out and I just need to touch the touchpad. Other times it goes from normal screen to black several times. I assume it is a software problem, but I'm technologically challenged so it could be a hardware issue.

Before going deeply into this, are you sure we're not looking at the usual battery saving techniques used by laptops?

I wouldn't know. As I've indicated, I'm technologically challenged. Computers are not my business or hobby, but I use them daily.

The laptop is plugged in and has been for days.

My power settings are:

Dim the display: Never on battery and plugged in
Turn on the display: 10 min on battery and 25 min plugged in
Put the Computer to sleep: 15 min on battery and 30 min plugged in
Adjustment for brightness: about mid-way on the bar on battery and high plugged in.

If this is your first laptop, the screen dims after a few minutes of no keyboard or mouse activity, then turns off a little while after that. Later, depending on the settings the hard discs shut off. The mouse or space bar revives.

This is about my 10th laptop. As I indicated in the initial post, there are times when adding or removing something from a USB port and the screen fades. There are times when it fades in, then out, then in, then out, etc. without any response to either the touchpad or keys. There are times when it will fade out while I am in the middle of typing.

I don't think this is a Windows problem. If you were a gamer I'd say to get an external graphics card regardless of the condition of your CPU one which Intel likes, but is really low end. I'm moving the thread to our Hardware forum where more expertise is available.

Just wondering if the Inverter could be on the way out ?

May also be worth testing the memory with Memtest86+ Guide to using Memtest86+ - Geeks to Go Forums or you could run Dell Diagnostics to see if that comes up with anything Run Built-In Diagnostics for Your System | Dell
