Dell makes it relatively easy to perform a BIOS flash and even encourages this in the setup guide of their products.

    I have had my dell xps 15z for only a weeks now but there were a few things that weren’t working as they should have been. I downloaded a dell bios update and ran this. Now my computer now will not even turn on, and I cannot find any help online. Pressing the power button turns on the fans and disk drive but then just turns off again after a few seconds. How can I get it to boot enough to reset the bios and get my computer back up and running?

    Thanks in advance.

      A bad BIOS update can kill a motherboard. If the BIOS can’t boot enough to update itself, I’m not sure how you can correct the problem. Since it’s still under warranty, I would call Dell and tell them it’s not working. They might have you send it in for a replacement motherboard.

    I have a friend who locked his self out of his computer BIOS password lock. When we type the password in the keyboard is not responding only with the exception of the enter key. I have taken the cmos battery out to try and reset it but this hasnt seemed to help. The keyboard is fine and the computer has no jumper settings. Can anyone explain to me how to fix this problem?
