    I have the fix. It's the control module for all the buttons. Take the back screws off including the stand. Pry the frame off it prys from the inside of the frame. Just pry outward all around it will snap off. I tried cleaning with deoit the small button control board it didn't work . So have your monitor in the on position and disconect the control board. Keep it on and put the frame screws stand back on. No more popping up calibration boxes. You can still power off your computer and the next day when you power up the screen will kick in as always. Call me mister fixit. :)

Niko 1906W LCD Flatscreen/Widescreen monitor. - the brightness screen/bar keeps popping up every 5 seconds, and wont close. This is very annoying. Is there anything that can be done about this to make it...


It sounds like the button is probably stuck down or the contacts are too close. Try tapping the brightness button a few times, maybe with some force, and see if the contacts will snap back in place. This could also be caused if the monitor was in a severely moisture-rich environment.

Brightness indicator windows does not go away


Dear sir This is common problem observed in many monitors compaq,HP,HCL,IBM this is happens mainly in rainy season due to moisture,by this moisture monitor button circuit get rust inside and button pad remain pressed. so it shows a strip at the middle of monitor like contrast or brightness. So this is minor problem just replace the monitor display control button sensor or circuit.Temporarily you can warm up the monitor by hanging a bulb of 60 watt nearer your monitor to takeoff the moisture.(Dont hang the bulb too near to the monitor). It definitely solves your problem.

Have a new gateway m-1631u. I have set the power setting to the energy battery saving power. I also set it to have the brightness dimmed a bit due to my sensitive allergy eyes plus I have chronic...


I have the same laptop, and the same problem. I went into the BIOS settings and disabled BIOS power management features. Windows can still use the power management features, but it is not competing with the BIOS doing the same thing.

This helped reduce how often the brightness pops back to max, but doesn't completely solve the problem. It will still go to max, and most of the time back to the set brightness after a second or two. Very annoying, but better than just being stuck at max brightness.

I think either the backlight inverter is buggy, or the driver that talks to the inverter is buggy. This is my biggest complaint with this laptop.

Brightness/contrast window pops up and scrolls through fast


The up/down button on your flat panel is stuck. Please contact Dell Technical Support to have the monitor replaced if its still within warranty.
