@osp Welcome to HP Community!

Let's perform a power reset as per HP standards:

Ensure your device is OFF.

Unplug all the external devices (If any).

Disconnect the power from the computer

Press and hold the power button for about 30 seconds.

Connect the power supply

Press the power button to turn on your device and check if the issue persists.

If the issue persists, after the above steps, try the below:

To recover an earlier version of the BIOS on your computer:

1. Turn off the computer.

2. With the computer off, press and hold the Windows key and the B key at the same time.

3. Still pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows and B keys until the BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

   NOTE: 

   If the key presses do not work, press and release the Power button, and then immediately, press the Windows and B keys at the same time, repeatedly, until the computer beeps or opens the BIOS update screen.

   The power LED light remains on, and the screen remains blank for about 40 seconds before anything displays on the monitor. You might also hear beeping sounds. Eventually, an HP BIOS Update screen displays and the BIOS update begins automatically.

   

   • If the HP BIOS Update screen displays proceed to the next step.

   • If the HP BIOS Update screen does not display, do one of the following depending on the condition:

   • Computer starts into Windows: The computer starts into Windows if the power button and keys are released too soon. Repeat the previous steps, holding the power button down for 2 or 3 seconds.

   • Power LED light turns off: The computer turns off if the power button is pressed and held down too long. Repeat the previous steps, holding the power button down for between 2 and 3 seconds.

   • After repeated attempts, the HP BIOS Update screen does not open: Your computer does not support this function or it has a hardware problem that is preventing the tool from opening.

Have tried the above points but nothing happens. Have been told that cmoc has been tried reset and that backup battery is taken out and in. Now PC does not make sound when it is turned on, but all fans go but no picture on screen. Do you see more neon before we can try?

Have tried to make a bios flash usb drive but can't get up to choose usb when installed. Which bios version should I use then?

@osp use the bios version available on the HP website for your device to create a USB Bios recovery file and if that doesn't work either, I suggest you talk to HP support and discuss your options, follow the below steps to get started:

1) Click on this link - http://www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
