My XBOX 360 doesn't power up

The console doesn't turn on and the green light doesn't come.

Do you have any lights on the power brick might try a new plug

Is the power brick lighting up? https://beta.support.xbox.com/help/xbox-360/console/check-power-supply

Sounds like you need a new power brick.

Hi

Can you please power down the Xbox 360 console remove the power cables from the console and the wall outlet for two minutes to allow the console to fully reset. After this connect everything back on and attempt to power up the console. If the console still
does not fully power on please disconnect any accessories and hard drives connected to the console then try power up the console again.

Can you also try following the support guide below.

Nope didn't work

Also my power brick is fine and nothing is wrong with it

you know that nothing is wrong with my Xbox 360 power. The problem is it doesn't boot up

Yes...that means the drive doesn't power up and/or spin up properly. The 360 always keeps power to the USB ports. I guess the drive detects that there's been a change in power (because the USB ports shut off when you power down, but if there's something
in the port, it powers it back on.), and the drive doesn't spin up because the 360 isn't on. But yes. It's probably the drive. Because it's Seagate. And Seagate makes bad drives.
