My Hp spectre screen is flickering. I tried external display but that too is flickering. I noticed this flickering increases in winters and comparatively decreases in winters. Also tapping or moving the screen flap has no effect on flickering frequency. (Flickering - entire screen flashes). Kindly help me to rectify this issue. 

p.s. - could it be due to dry soldering issue of onboard graphics ?

Hi @Raajit 

If they were soldering problem the CPU does not work because the integrated graphics are in the CPU. Try updating the BIOS and the integrated graphics drivers.
