Lenovo Ideapad Y430 LCD Screen Flicker Problem

I had my old HP nx9040 notebook replaced about 7 months ago with a shiny new Lenovo Y430 ideapad and everything seemed to work fine

until a few weeks ago when I noticed the screen flickering (sort of flashing) regularly every few seconds after boot up. It used to be only for a few minutes but lately become qutie annoying that I reported the problem to my office technical support.

I know it's not an LCD screen problem so I requested an LCD monitor to be temporarily used since it the flicker strains my eyes that I can't work anymore and stare at the computer screen.

The laptop is still under warranty and I requested for Lenovo Support Singapore (with office in Citibank Tower, Paseo de Roxas, Makati) through my supplier Zenshin.

Will post updates, actual problems, workarounds and solutions later

UPDATE: Lenovo replaced my notebook's LCD for free (took two weeks with Lenovo Philippines through Zenshin, my supplier) since it's still under warranty...a month before warranty expiry :P
