Flickering line at the extreme bottom of my laptop screen. 

This happens when my laptop off suddenly due to my battery drains. After connecting charger, when i start my pc i saw this flickering line. I shutdown and remove my power adapter and then i removed my battery and then wait for some time and then i restart my pc. when starting it didnt came, i think it was gone, after some time the flickering line appears. I restart again then at the time of starting also it appears. It was flickering like a dotted line very visible while playing movies.

I updated BIOS recently. but nothing is gone. Most of the times while starting the system the flickering line is not coming. It visible after 5 minutes of starting.

@Arun48

Are those lines visible in BIOS?

[Arun48]

For the first start it was not visible, that means it is not visible for long time after start. It is visible after continuous start, that means it is visible while using the system for 15 minutes and then restart. The flickering line is at the extreme bottom of the screen and it is not at the window of BIOS(Extreme bottom the screen).

Please run an Extensive System Test and let me know if you see those lines

- Turn it back on, then tap the Esc key repeatedly until the Startup menu screen is displayed.
- Press F2 to select System Diagnostics.
- Click System Tests, then click Extensive Test.

Run the system extensive test for about 7 hours, but no error displayed. everything is perfect. Is the flickering line have any relation to Intel Graphics Driver. because My intel Graphics Driver was not opening.
