System completely Dead wouldn't boot
My MacBook Pro is completely dead. Wouldn't boot at all despite I hold down the power button for more than 10 secs. No sound of hard drive trying to turn or displace light. When I plug in the power supply the connector' slight can faintly be seen blinking, not the normal yellow bright blinking light when charging. Is this indication that my battery is dead or bigger problem, like dead hard drive? Appreciate you help & advise!
Is this a good question?
