Hi,
i am a computer technician i got a laptop from my friend to get it fixed.
the problem is pretty common in this model but still cannot pin point the problem.
i will tell you guys what i already did.
1) Updated the bios to current up to date version
2) Updated Graphics Card both Nvidia and Intel
3) Performed clean Installation
4) Checked and reconnected the connection of LCD at both ends (Motherboard and LCD panel)
5) Changed Ram
6) Changed Hybird drive to SSD clean install
7) Changed to HDD clean install
8) Changed Battery
9) Run with battery power only
10) Run with AC power only (Battery disconnected)
11) Disabled each graphics card one by one to run windows
12 Installed intel rapid share technology app
Now i have run out of options please some one help me out.
Problem:
1)The problem is it shows blinking horizontal lines on lcd screen but fine when using external screen using HDMI
2) There is also no horizontal Lines blinking when it is in Bios or windows safe mode
Edit : I think it could be a driver problem but cannot figure out which one as LCD works fine in bios and safe mode and graphics card also works fine on external display
