tsty,

Thank you for using Dell's Community Forum.

How often in a normal session does this happen?
It probably is that your system flickers only when it throttling down the CPU to conserve power.

Actually quite a bit.  Just during normal operation (when I am using) the screen seems to flicker a couple of levels of lightness.  The "to black" flickering happens less but it also happens during use

Hi,

 

I think I'm having the same problem with my D600. Its flickering behaviour is *similar*, though not exactly the same. Actually, my D600 usually only flickers when it is turned on (it doesn't matter if it's a full boot or a return from hibernation) and the flicker disappears after about 10 minutes. There is no difference when the laptop is connected to a power outlet. A friend of mine also has a D600, but his does not display any flickering.

I'm wondering if I should call Dell support to have this fixed. Or can it be solved by installing other software?

Corey - any ideas on support for this problem?

Several days later and still the same no better or worse

 

Mine new D600 flickers in two different ways:

1) Constant flickering like there is a loose connection in the video display and/or card.

2) Will periodically flash twice for less than a second. 

Hi,

I have a hunch that it *may* have something to do with the speedstep driver that is incorporated in WindowsXP. Could you try switching Speedsted off in the BIOS? (hold F2 while booting). Your computer will seem incredibly slow, because the processor will automatically be set in its lowest speed setting, but on my laptop, at least the flickering was gone. Could you try the same? At least we'll know for sure that the speedstep driver is indeed the problem. After switching speedstep back on ;) I have been searching the net on known issues with intel speedstep and dell laptops, but so far i've had no success.

I have had this same problem with my latitude LS, and some research leads me to believe it may be the LCD inverter.  I've found one, but have no idea how to install it.

Perfect! Thanks Corey.  Now I just hope that this fixes the problem.
