Friends - have been stuck on this issue for a month now and would appreciate your insight.

My problem -

- is a Dell E1705 laptop - (with ATI Radeon Mobility X1400 video card) - refusing to turn on (or power up) the lcd display - most of the times. When it does not work I do not even get to see the dell boot screens. But the hard drive lights blink and the laptop appears to be booting up.

- Once in about 100 times lcd display works with the Media Direct power button - never with the regular button.

- Successful boots achived with battery and ac power and when it works everything looks normal.

What could be the issue here ?
What would explain the random nature of the display turning on or off ?
Can video cards behave erratically ?
How to ascertain if it is a video card (removing without replacing with another video card is not an option on this laptop) ?

hey there,

this kind of problem i would advice you not to try to repair it by yourself as the video card in laptops is integrated and so try to get the advice of an IT professional instead. but never try to repair it by yourself buddy

Thanks for the reply - actually in my case the video card is not integrated with the mother board - apparently when I bought the option for video card provided by Dell - they replaced the mother board with one which did not contain the video card. My laptop is about 2 and half years old - the display used to be great and all but then I do not want to spend another $100 odd for diagnosis and another $200 for some part replacement and another $40 odd for mailing -- not when there are new available for $600 with newever CPUs but smaller screens.

The nvidia go geforce 7900 gs are defective. The gpu's overheat and its a manufactures defect. Dell is not good about replacing defective parts after the warranty even if its a manufactures defect. Just thought I would shed some light on a bad situation. Look at the nvidia page or just type in nividia card gpu problems with the 7000 and 8000 series.

Forgot to add my own deductions on the issue - I could be wrong with these

I get blank display - even when an attempt is made after the laptop is been turned off for hours. This may leave out an issue due to overheating.

I cannot figure out if it is a hardware or a software issue - if it was hardware I would have expected the condition to not change with attempts -i.e display will not show always.

Could something be wrong with the display power up software ? What is the software that decides if the display should power up - perhaps it contains a flag which gets turned to off most of the times.

If anybody knows more about this things - you are welcome with your analysis - the answer to this issue will always be a positive experience for most of us.
