Hello,
I have Amilo M1425 laptop and I started to have this problem for 3 days:
When I open the screen normally (90 degree) the screen is very dim (similar to the famous inverter problem) but when I change the screen angle (around 45 degrees:lid half-closed) the backlight returns normal (in fact, I am writing this message under such viewing angle !!!).
What I think is the lid-close detector (which functions normally to turn off the backlight when it detects lid closing to save power) is malfunctioning and is detecting lid closing even though it is still open so it turns the baclight off.
Now I need you to test my theory but I don't know the lid-closing detector mechanism in amilo M1425 notebook, which in other notebooks is a small pin near the hinge. So anyone an help me here?!
Thanks in advance
