Good afternoon friends of the forum. It tells you the story of this laptop. This laptop comes in with the chipset in short. I order a spare motherboard, I mount it and I realize that it does not display on LCD. If instead I connect in hdmi or vga it works but only after loading the operating system. I can't get into the bios because before windows I see a black screen. I tried to clean the lvds connector but nothing to do. I removed another monitor and LVDS cable from another identical laptop and it always remains with the black screen. I also tried to take the bios from the old motherboard but the same defect. I checked for safety the lid sensor and it works, when I close a magnet he closes the contact.
