A user complains that his notebook display has started to go dim intermittently. You suspect the backlight might

need to be replaced, but you want verify that the backlight is failing before you replace it.

Which of the following would be BEST to check before replacing the backlight?

Check the display inverter connections.

Make sure that the dimming isn't being caused by a power saving method that has been configured to
conserve notebook power.

Make sure the battery is still able to hold a charge.

Make sure the power adapter cords are plugged in securely.

Check for cracks in the power bundles that go from the laptop to the display.
