Understand what the orange,green light on the Computer power button means? And the power supply problem in General

The power light illuminates and blinks or remains solid to indicate

different states:

No light — The computer is turned off (S4, S5, or mechanical OFF)

Steady green — The computer is in a normal operating state

Blinking green — The computer is in a power-saving state (S1 or S3)

Blinking or solid amber — See "Power Problems"

If the power light is steady amber — The computer is receiving
electrical power, but an internal power problem might exist.
Ensure that the microprocessor power cable is securely connected to the
system board.

 

The following table lists the ACPI power states from highest to lowest power consumption.

Power state	ACPI state	Description
Working	S0	The system is fully usable. Hardware components that are not in use can save power by entering a lower power state.
Sleep (Modern Standby)	S0 low-power idle	Some SoC systems support a low-power idle state known as Modern Standby. In this state, the system can very quickly switch from a low-power state to high-power state, so that it can respond quickly to hardware and network events. Systems that support Modern Standby do not use S1-S3.
Sleep	S1 S2 S3	The system appears to be off. Power consumed in these states (S1-S3) is less than S0 and more than S4; S3 consumes less power than S2, and S2 consumes less power than S1. Systems typically support one of these three states, not all three. In these states (S1-S3), volatile memory is kept refreshed to maintain the system state. Some components remain powered so the computer can wake from input from the keyboard, LAN, or a USB device. Hybrid sleep, used on desktops, is where a system uses a hibernation file with S1-S3. The hibernation file saves the system state in case the system loses power while in sleep. Note  SoC systems that support modern standby (the low-power idle state) do not use S1-S3.
Hibernate	S4	The system appears to be off. Power consumption is reduced to the lowest level. The system saves the contents of volatile memory to a hibernation file to preserve system state. Some components remain powered so the computer can wake from input from the keyboard, LAN, or a USB device. The working context can be restored if it is stored on nonvolatile media. Fast startup is where the user is logged off before the hibernation file is created. This allows for a smaller hibernation file, more appropriate for systems with less storage capabilities.
Soft Off	S5	The system appears to be off. This state is comprised of a full shutdown and boot cycle.
Mechanical Off	G3	The system is completely off and consumes no power. The system returns to the working state only after a full reboot.
