Failed BIOS update - Dell XPS 8500

Jump to solution

I went to the Dell product page for my computer - Dell XPS 8500, and ran the scan to check for updates.  3 updates, one of them for BIOS.  I ran the updates and initiated the BIOS update.  Midway through it appeared to get hung up and my machine froze.  I left it for an hour, came back and still no luck.

So I rebooted the machine and of course now it won't boot up.  I have power and can hear the fan, but no lights on the box and no screen input.

Looking though the manual and on this forum, I've tried resetting the BIOS jumpers, and removing the CMOS battery.  When I rebooted I saw lights on the box this time but it shut down after 30 seconds, and now back to the same problem.

From what I read on this forum I'm SOL unless I buy a new motherboard.

Just thought I'd check if anyone had any other suggestions.  If not, where can I get  a new motherboard for this?  The product page for my model doesn't list it as an option...

Thanks for your help!

Also - I found this article on the Dell site:

Has anyone had success creating a bootable USB to update BIOS in a situation similar to mine?

I Will try this tonight...

That only works if you can boot the system...

Did you power off, unplug and press/hold power button for ~15 sec before removing the motherboard  battery and did you press/hold the power button for ~30 sec after removing the battery to see if you can clear BIOS?

You can find motherboards for the XPS 8500 here and probably on eBay.

Ron - thanks for your suggestions.  I tried holding the power button before and after removing the cmos battery but no luck.  I also tried the bootable usb and that didn't work either.

I think i'm stuck with buying a new motherboard.  I called the Dell Spare Parts number you provided but they don't have any motherboards for that model in stock.  

The link you provided lists 3 motherboards, each with a different code or model number - i'm not really sure.  Do you know if it matters?  Is there anything i need to consider when purchasing a motherboard? i.e. the windows product code and version, etc... i've seen a few posts on this site mentioning making sure the motherboard supports the windows license key, etc)

These are the 3 models listed on the site you provided:

YJPT1 - Motherboard, H77 Chipset For Vostro 470 / XPS 8500

NW73C - Motherboard, H77 Chipset For XPS 8500

When did your warranty expire? If it expired less than 6 months ago, you might be able to get Dell to fix it, assuming they can get the board. They had a policy to replace a board -one time only- if it failed a Dell BIOS update within 6 months after the end of warranty. I don't know if that policy still exists.

Those are all different revisions of the same motherboard. I don't know what the differences are. They could be as simple as a different supplier for one of the components on the board all the way up to a change in the circuit layout.

Maybe Dell Spare Parts can tell you about the differences among the 3, or at least tell you which is the most recent revision,  even if they don't have the boards available...?

All three support the H77 chipset which is a key issue.

Look at your motherboard for the sticker to see what version you have now. If you can't find out about specific differences, you may want to get one that's the same version, assuming it's one of the choices available.

You should look elsewhere if Impact doesn't have the revision you want and/or for price comparisons. And always ask if the board is new, used, refurbished and about the warranty.

Oh, and as for version of Windows, if you're running Win 7, it shouldn't matter. Win 8(.1) and Win 10 store the product key in BIOS so you may have to contact Microsoft for a new product key to activate Windows after you replace the board.

Thanks Ron.  This is helpful.

When you say "...All three support the H77 chipset which is a key issue..."

you mean that all three will be compatible.  Correct?

The specs say the XPS 8500 uses the H77 chipset so I assume that's what your current board supports.

If the chipset on the replacement board isn't H77, you'd have to reinstall Windows and all your software on the HDD because the chipset affects how Windows gets installed and runs.

ok good to know.

I was looking at this, but it appears to be lga1155 chipset so I think that's out.

Also, for the windows key, I purchased the computer with Windows 8.0 installed, and recently did the upgrade to Windows 10, so I'm assuming I will still need to contact Microsoft for a product key.

Would you know if Dell support would have a copy of the key I purchased in my account information?
