Display does not turn on from standby. (D600, Mobility Radeon 9000)

Question

Probably it is the same problem as AJ76 posted before.   The problem is the following: The display does not turn on properly or does not turn on at all from standby when connecting with remote desktop (Windows XP) to my Latitude D600. In this case the display shows either greyish patches at the border or remains black, respectively. Because the display is not switched on, remote desktop cannot login either. It is possible to switch off and on the display remotely, but it is not possible to switch on the display from standby. I tried various combinations of screen saver and power saving settings to overcome this problem, but none of them helped. I installed also the latest driver version (6.14.10.6476), but it did not help either.   If somebody has experienced the same problem, then please let me know. Thanks in advance!

When you say 'greyish patches' do you mean the backlight is working. Is the hard drive light blinking when you try to do something in that state? I had a similar thing happen to me but in my case whenever i did things like open the lid on a turned on laptop, comback from hibernation/standby, turn on the laptop on the battery the screen would flash, turn black but the backlight would remain. However, I could see that the system was 'frozen' because I couldn't even toggle the caps button. Try this in yours.

I mean by greyish patches that the backlight is working, but the illumnation is not uniform. A sort of ghost image appears on the screen.   In my case, the system is not frozen, the hard drive light is blinking and i can turn on and off the caps button. However, the display remains blank, even if i move the mouse or press a button. The display remains locked in this strange state. I can set the system again into stand by using the stand by button.   Thank you so far for your information, however, i did not exactly understand what you mean by omega drivers. Could you please precise that?

omegadrivers.net - Alternative drivers to ati's and nvidia's official video drivers. They are more flexible and stable I found. People seem to like them.
More info on the omega site: http://omegadrivers.net/ati/ati_faq.php

Thanks for the information. I installed the omega drivers. I could improve other settings, but the main problem is not solved. If I connect with remote desktop, the system wakes up from stand by except the display. Therefore, Window XP's remote desktop cuts the connection and no session is established.

OK, never let it be said that all I do is complain. The new BIOS update seems to solve my blue-screen/haning problems when coming out of stand-by. BIOS A15 was released on 2/4/05 and specifically targets the issues. Better late than never!

Thank you to DELL for finally addressing this. :smileyvery-happy:
