First, you should reprogram the Bios chip back to the original Bios if you had made backup. If not so, find a bios dump. Probably, other technicians will upload one for you.
After you made the Laptop turn on for 5s, start diagnosing voltage problems.

Before you reprogrammed Bios, leds could turn on and the fan could spin. But using the new Bios, it has no fan,no led. So, you should try different Bios dumps multiple time until you reach the original state of the laptop that had spinning fan and lighting leds, even though it turns of after 5s.
