Sorry, i thought i opened this threat in the German forum.
I did not completely understand your translation. I s it possible to post it once again in English?
Here is once again the problem description in English:
After switching on the notebook the Power LED is lightning, but the display remains completely black.
The LED of the hard disk / CD drive flashes shortly an then remains also black. The hard disk is running mechanically (it is possible to hear the sound of the running hard disk)
I have the tryed to start the computer with a bootable CD, but unfortunately the result was the same. The CD was detected by the CD drive (LED is flashing and the disc is turning a several time) but the the CD drive stops and the behaviour is the same as described with the startup with the hard disk.
I have tryed to start the notebook either with battery and with the computer connected to power.
I hope this translation hels for the english forum
