Hi @pravnav ,
if your laptop is not giving you some beeps, it could be only BIOS time issue or something like that. So, try to reset your BIOS using CMOS reset:
# Turn Off your laptop
# Unplug the power adaptor
# Unplug main battery
# [https://www.youtube.com/watch?v=G3av1thyp2U|Disassembly your laptop to the motherboard]
# Find the little battery in the slot on the motherboard
# Remove this battery
# Put back this battery
# Try, if it’s booting properly - You must insert Hard drive to the slots, also, if you will remove RAMs, on the boot-up, they must be placed in the slots.
If It’s still not working, try to start your laptop without HDD, if It’s still same, let us know and we will find a different solution for your case.
