If it shows a picture, the internal screen or its cable has failed. If it stays black too, suspect RAM seating, a corrupted BIOS, or a GPU … Read more
Quick Answer The most common cause is a loose RAM stick, a failing AC adapter, or a battery that can’t sustain power. Remove the battery, reseat the RAM, and try booting on AC power alone.
