Ok i will check
Additional information Pressing "D" button ->Screen tunr on and Red, blue Green White pattern change again and again . Test patterns.
So Looks like screen is ok. Maybe.
...and If i press D button, it means keyboard is good?
Memory voltage 1.5V present.
When I remove DDR3 memory, appear different error code and flashing the 3 leds (battery, HDD, wifi) on keyboard frame... And as i read it is an DELL error code.
Ok i will check DRAMRST#...Leave a comment:

Yes it is not posting, just debug card show 98 or d7
I try the USB keyboard, nothing happen, not show numlock leds.., But USB 5V is ok. Mosuse light on normal USB port and Esata/ USB too.
I start to check voltage on keyboard conn, but looks like ok +3,3V or 5V
Dell laptops need every time the Keyboard?
I mean I not attach keyB+touch -> Fail I attach the keyboard+touch, ->Fail Becasue keyboard is maybe not good.
So should be start without keyboard?
Bios can be cause this problem?
