HP All-in-One PCs - Testing the AC Power Adapter

This document pertains to HP and Compaq All-in-One computers that use an AC power adapter and power cable combination.

Follow the steps of this document if your All-in-One computer does not power on, the power LED is off, there is no fan noise or beep tone, or if the

computer does not respond when pressing the power button.

The cause of the lack of energy can be a defective AC adapter, power cable, or a defective component on the system board of the

computer. Use the information in this document to identify the cause of the power problem.

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is

sometimes referred to as a hard reset. Use the following steps to perform a hard reset on your computer:

1. Disconnect the AC adapter, power cord, and all connected devices from the computer. This includes removing thumb drives and camera-type memory

cards from card reader slots.

2. If the computer is on, press and hold the power button on the computer until the computer shuts off.

3. With the power off and the AC adapter and power cord disconnected, press the power button on the computer for 15 seconds. The power light indicator

on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

If your computer does not power on, continue to the next section.

Use the following steps to determine whether the AC adapter is working properly.

1. Confirm that the AC power adapter is a genuine HP part. Do not use a non-HP AC power adapter on an HP computer.

For best performance, use only the power adapter that came with the computer and configure the power management settings

for optimal performance based on your usage habits.

The power adapter wattage information is printed on the bottom of the adapter.

When using a power adapter that has a lower wattage than the computer requires, there might be some trade-offs. The CPU clock rate might be reduced to save power, which can cause programs to run slower, or the power adapter itself might become warm to the touch. 2. Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage.

. Check that AC power is connected to the system board properly by examining the AC adapter connector on the back of the computer. Sometimes the power adapter plug is misaligned due to the pressure of other cables.

. To verify that the wall outlet is working, plug the AC adapter directly to a wall outlet. Do not plug into a power strip, surge protector, or a secondary power source. Unplug the AC Adapter from the wall outlet and plug in a small lamp or other device that you know is working. If any of the wall outlets are not providing power, test the lamp or other device on a different wall outlet. 5.

NOTE: If the AC Adapter test is not available, update the UEFI version. See HP Hardware Diagnostics. 9. When the test is finished, the results display. If the test PASSED, there is nothing wrong with the AC adapter. Do not replace it. If the test result is FAILED, record the failure ID code before replacing the AC adapter. (The failure ID code does not display unless the adapter is plugged in.
