Laptop won't turn on

My laptop won't turn on. I have troubleshooted it and it turns out it is because of a hard drive problem.

Here is the scenario:

Laptop won't open if this seagate hard drive of mine is connected, power indicator only blinks, as if it is in hibernate mode, fan is not moving, totally not on.
I tried removing the hard drive, then turning on the laptop. The laptop now flashes BIOS.
I tried connecting a different hard drive, western digital hard drive, Laptop flashes BIOS.
I tried connecting my old seagate hard drive, the laptop wont turn on, still fan not working just the blinking light that looks its in hibernate mode.

So in here I can see the seagate hard drive is the one who is faulty but I would like to ask, is that even possible? How come a hard drive can prevent a laptop/pc from booting even just to BIOS?

Because there is something wrong with the drive that is causing it. I've seen this plenty of times in my 20 years of working on computers. Most likely an electrical issue on the circuit board on the drive.
