Hello guys... i'm out of any further idea.
Since i got this laptop i NEVER had any issues with it - today i opened the backside, to vacuum and blow out my fans IN the laptop.. So i removed, those about 10 screws - unplugged the HDD to remove the cover and did my cleaning. After this i put the cover into the right position, plugged the HDD, added the few screws, plugged the power supply and pushed the ON-button... my laptop is booting fine - i hear that it starts up until the locking-screen - BUT NOW THE ISSUE - the screen stays JUST BLACK since this... anybody knows about this problem?
Wont be happy if that means the end of my great working laptop 🙂
thx in advice...
