If I try to switch on my Lat D800 with the power-on button it quite often won't start up, but just blink the creen, light up all leds and after about 4sec everything is off power again.

 

I see the exact same problem reported in 2003 for other D800 and also for Insp 8000 series.

 

I did narrow the fault down to the graphics card. If it hw-wise installed (present on the main board)  every single power-on attempt succeeds, if I take it out I have to at least try 4-5x untill I get a successful power-up.

 

I have attached the graphics card to the board in any possible way zo not run into connectivity issues - no avail.

 

My solution is just to never cold-boot the system, alway have it in supend or do a restart, but hardly ever a shut down.

 

Dell-Mods - any hints for the well-known problem??
