Black display, normal boot
Im having the headache with Asus X405U.
Whats going on is that the screen is black, however laptop boots normally and works smooth on external monitor.
I’ve bought new display cause i was sure it is broken display, connected it and its still the same.
Since that i have checked everything, RAM is soldered to the mainboard and there is no other memory module, i removed internal battery and did CMOS reset by pressing power button for 60 sec. I’ve been trying to find lid switch but unfortunately couldn’t locate it, so i went to power options and disabled it in the settings. Still no luck.
I was also able to get to bios via external monitor, reseted it and been playing with lid settings there - no luck.
What i find weird is that sometimes display shows up for 3 sec and goes black again.
It happened to me when i was pressing random keys on the keyboard.
Same happened when i disconnected keyboard while the laptop was running.
I tried to replicate it again but no success.
One thing that comes to my mind is LCD flex cable but it seems good and as i mentioned above sometimes display lights up. I tried to bend it and move - there was not even a glipse.
Did anyone had similar issue? Im seriously loosing patience.
Questa è una buona domanda?
