HP nx9010 Laptop Screen Issues
Posted on 2009-04-08
We have an HP nx9010 laptop, whose screen appears to turn off and on rapidly (approximately once every second). The screen is not simply becoming dimmer, if held to a bright light, there is no sign of an image when off, so I do not think it is the backlight.
The frequency of the flashing is not related to any physical movement of the laptop. Interesting though, when an external monitor is plugged in, the laptop screen stops flickering and returns to normal operation. As soon as the monitor is unplugged, the screen starts flickering.
So my question is, we hope to replace this machine, but before we can do that, the user needs a quote for repair. Based on connecting the external montior, I am thinking this might be a video card issue. Or would you think it is the LCD screen itself. Flicking occurs at all times, even in BIOS.
