Computer won't turn on

[1TommyG]

I was working on my desktop and left for a period of time to perform errands. The machine had gone into sleep mode as usual, when I returned and shook the mouse the machine did not wake as normal. I pressed the start button and nothing happened. I tried this several times and still nothing. I unplugged the unit and waited 10 minutes, plugged it back in and pressed the start button but nothing happened. I changed power supplies with one that was working and it still did not start the computer and the power supply did work on my other computer. What should I do next, please advise.

@1TommyG,

Thank you for posting your query on HP Community,

This looks like a possible hardware failure with the PC. However, I would recommend you try these steps here: 

Perform a Hard reset on the PC: 

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 a computer:

1. If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 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.

You may follow the steps from this support document to ensure you have followed all the steps before confirming this to be a hardware issue. HP PCs - No Power or No Boot Guided Troubleshooter

If you have followed the steps suggested and still having the issue. I would suspect this to be a possible hardware failure. 

I would recommend you contact our HP support team for further assistance.

Thanks for the info, but I had done all that and nothing so I did contact HP support and now I am sending the unit to them for repair.
