Before I buy your new Updating and Repairing Laptops 2nd Edition, please
"hear me out"

I have an HP Pavilion ZD8000 Notebook, and I have problems with the video
adapter card. I've been using my Flat Screen LCD TV as my primary display,
instead of the notebook's 17" LCD, and it's been working great for the last
year and a half. Suddenly, I get the "blue screen of death" with the
following error:

"DEVICE DRIVER "ATI2DVAG" GOT STUCK IN INFINITE LOOP. THIS USUALLY
INDICATES PROBLEM WITH THE DEVICE ITSELF OR WITH THE DEVICE DRIVER
PROGRAMMING THE HARDWARE INCORRECTLY", then it gives me this hex stop error:

STOP; 0X000000EA (0X89AEB378, 0X89B138A0, 0XF78CACBC,
0X00000001

Then when I reboot, it goes blank right after the Windows logo display, and
if successful, windows gives this error:

VPU RECOVER was unable to fully recover from a hardware deadlock and has
switched to software rendering. To restore hardware rendering, you must
restart your computer. Do you want to restart your computer now? YES or NO"

I've tried Updating to the latest video driver, both from HP and from ATI
(which is now AMD, GOD help us) to no avail, errors are permanent.

I can still use my computer if I use only the notebook screen instead of the
TV, but I cannot use the video card at all, it defaults to windows generic
VGA driver.

According to HP, the adapter is bad and they want $400 for a new one, and
ATI (AMD) has no support for it, since I bought it from HP. I don't have the
$400 for a new card, the notebook is out of warranty (just my luck) and so
your book seems a better choice for me, then I can buy a new card and
install it myself once I can afford it.

In summary, my question is this: Do you show how to remove and replace the
Video Adapter in your new book?

(Sorry for the lengthy explanation, but I hope that you can help)

Thanks!

According to the ZD8000 service manual:
http://h10032.www1.hp.com/ctg/Manual/c00291986.pdf

...that system doesn't have a video card, the graphics are built-in to the
motherboard.

For additional confirmation I recommend booting a copy of the Knoppix live CD
http://www.knoppix.com (which contains ATI drivers) to see if the video works
properly in that environment.

If it does, then I suspect a software problem. In that case I would recommend
you perform a product recovery to reinstall the OS, drivers and original
software from scratch.

If the video is indeed defective, then you would have to replace the
motherboard.

A new motherboard would be very expensive, the system might not even be worth
it. In that case you would be better off disassembling the system and selling
off the parts on ebay, then purchase a new system and start over.

Unless perhaps you can find a used motherboard that matches your system:

My book does indeed show how to completely disassemble a laptop, and the
included DVD shows various disassembly, repair and upgrade procedures as well.

Upgrading and Repairing Laptops 2nd Edition (with 1.5 hour DVD)
http://www.amazon.com/dp/0789733765

But perhaps the best thing you get when you buy one of my books is me. <g>
Meaning that I am willing to answer questions and provide access to a support
forum exclusively for my readers.

Thanks for your interest, Scott.
