Front Panel not Detected Error

Hi ShaneJayHayes,

You have not provided the model of your Dell.

My first suggestion would be to reset BIOS defaults.

Inspiron 570

Not sure how to reset bios

Here are the instructions.

Have you done any work inside the case that might have caused this?

I know this is an old thread but I felt I could help prevent a lot of grief for some folks out there by sharing this story regarding the error message upon startup that reads "Alert! Front Panel not detected, press F1 to continue, F2 for Setup" or similar.

This repair was a stock Inspiron 570 in which lighting came into the DSL modem via the phone line and then went down the Ethernet cable and blew up the Ethernet circuitry on the mobo. This happens a lot in NW Alabama. The PC would never shut off or sleep, it would start to then after a brief, correct orange power LED it would come back to life, and the power LED would revert to white. If I went into BIOS and disabled the onboard LAN it would function properly but I wanted to resell this thing. Frankly, although everything else worked and I could have installed a wireless adapter in the PCI slot or a wireless adapter or Ethernet adapter in a USB port, I just wasn’t sure what else would turn up later due to the severe ESD/lightning hit.

So I found a used but working mobo that was an exact duplicate (Dell part # 4GJJT) on that online store that rhymes with ‘decay’ and slapped it in, booted up it up and BANG….up pops “Alert! Front Panel not detected, press F1 to continue, F2 for Setup”.

You MUST have the front panel USB ports connected to the mobo USB #17 hiding next to / underneath the PCI connector on the mobo. The mobo is silkscreened “F_USB1’ next to the connector, the ‘F’ most likely means ‘Front’. The other 2 USB ports on the mobo closer to the front are labeled “IN_USB1” and “IN_USB2”. I have to assume the ‘IN” means ‘Internal’.

The front panel’s USB cable has a green connector and must plugged into the green mobo USB socket labelled “F_USB1”. I had done this BUT….because it was so close to the PCI connector it was NOT fully seated! I re-seated it fully and no more “…press F1”.

To be honest, I found this info on another forum (not Dell) and when I re-checked how I had installed the USB cables onto the new mobo I discovered it was not fully seated. I hope this helps!

Hi Tonyruck,

Excellent post. Thanks for that update.

While there's really no problem mentioning Ebay, I got a kick out of your reference to "that online store that rhymes with ‘decay’". :emotion-2:
