To try changing the power light to green on an HP computer with a flashing green light on the power supply:

1. Disconnect the power cable from the back of the computer.
2. Press and hold the power button on the computer for 10 seconds.
3. Plug the power cable back in and check the light.

If the light is still flashing:

4. Unplug the power again.
5. Flip the voltage switch on the power supply to 220V for a few seconds.
6. Flip it back to the original setting.
7. Plug the power cable in again and check the light.

These steps may help reset the power supply and resolve the blinking green light issue.
