I was working on an ac adapter issue and updated my BIOS to check AC adapter. Selected F10 to save BIOS update. Something went wrong because when the system rebooted. Now I get a 2,2 followed by a 3,1 light pattern. I don’t have an old version of the BIOS but I do have the latest BIOS from Dell. Can I use CH341A programmer with a test clip to program the flash with the latest bios file from Dell?
Yes you can. Use the ch341A programmer software and re-flash the bios with the official bios from dell. It would work.
Thank you for the info. Waiting on the programmer to arrive.
