HP Pavilion zd7160us won't boot after BIOS upgrade...

I just upgraded the BIOS from a driver on the HP website and now after you see the HP logo it will beep once and show me "Unsupported wireless network device detected" System halted. Remove the device and reboot."

Problem is that this was due to their BIOS upgrade and the wireless device they're talking about is the built in card I have.

Does anyone know of a way to clear this up without doing something like ripping off the top cover and pulling out the CMOS battery?

Can you access the BIOS on startup? When the HP logo screen appears, press the F10  key on the keyboard to enter the Setup menu. Go to the Boot menu and remove anything that looks like it allows booting from a LAN device.
If this doesn't work you will have to physically remove the wireless card
Here is the guide to do so, click on the left link for "Wireless LAN Mini PCI card"

Once the computer starts properly, shut down and reinstall the wireless card.

yeah, I can access the BIOS, but the new BIOS is the problem. It's not really trying to boot from the NIC card, as soon as it displays the logo it beeps and throws that error. It doesn't have a chance to boot from the HD or the cd/dvd. I have the Windows CD in there and it skips right by it.

The only thing I can get at is the BIOS itself. I tried putting it back to factory settings and that did nothing so the only other thing I can think of is opening the whole laptop up and removing the CMOS battery and jumper so it goes back to the factory CMOS.

However, I don't know where the CMOS battery is for the zd7160us motherboard. That's why I was hoping to find some way of doing this without tearing the computer into little pieces.

Removing the CMOS battery won't do it as the BIOS which you flashed too is now the default BIOS.
You need to remove the wireless card (very easy to get at) as in the guide I posted, click on the left link called "Wireless LAN Mini PCI Card"

and then restart the laptop without it. Then reflash back to the older BIOS.

It ended up that HP was willing to take it back to service it because of what happened with their 'recommended' upgrade.

I'll give the points to you, sparkmaker, since your solution would have most likely cleared the problem. However, if someone at HP is willing to take the thing apart instead of me having to take out all the screws, I'll do that. :)

Thanks.

Definitely the right decision since they were the guilty party with a bad update.
