Asus x401a laptop screen went grey
At Starbucks I shut it down and came home - it was sitting on the floor of the car inside a laptop bag along with a Lenovo - the ride had some bumps. At home, the screen became grey but I can hear Windows booting sound!. Connected an external monitor and it worked fine.Using the external monitor, I also did a fresh install of WIn 10 and activated it. But the symptoms remains the same.
Only known hardware issue is the web cam, a while back - I had it replaced which worked just once.
Win 10 device manager shows all hardware installed (other than the web cam) ... memory, cpu etc. I tried F8 to switch the monitor but not responsive.
I tried some methods from online such as pressing & holding the power key etc. Tried just the power cord too. No luck
I suspect LCD cable became loose - or cmos battery related. LCD screen has been fantastic when it was working.
Anything I am missing? Any other tricks?
