[ameesh]

hello all

i need your advice and guidance

I got this acer E1-572 with motherboard LA-9532P REV:1 .Intel Core i5 processor with default intel gpu. DISPLAY IS NOT WORKING.

I already reprogramed the bios with acer e1-532 bios, now the display is working but now the problem is, when i press the power buton, the power light is on but the display is taking too long to start approximatly 17 sec.

what exactly will be the problem , how can i rectify the issue.
