I can't use PC after power cut. Display  with 5 icons shows in bottom right corner. I can only navigate the Display which comes up with the on/off button. An error message it says HDMI cable not found. Any ideas? With thanks.

Hi@J4x, Welcome to the HP Support Community!

We reviewed your post and I understand that the All in one desktop is not Powering ON,

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you follow the below steps and check if it helps

Do you see a light at the place where the charger connects to the laptop? If yes then it indicates that the charger is all fine.

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.

F6 + Power Button

• CMOS Rest ( combination of windows button and letter 'V' then push the power button ones and release the windows and letter 'V' after 5sec

If the laptop does not power on then please continue with the below steps:

• Disconnect the charger and remove the battery out.
• Connect only the battery and check if the laptop powers on.
• Likewise, remove the battery out (if removal battery ) and connect only the charger and check if that helps.

Keep me posted. Happy to help!
