Dear all Fellows at the Forum here,
For of all, I am NOT sure if it is the right place posting in sections of either pheonix unblocking request or award BIOS unlocking request.
I am on a “mission impossible quest” (as many other people I contacted at different forums/websites including Sony’s official ) that I am trying to replace /disable the existing Nvidia GeForce 8600M GT-512MB video graphics card which is soldered on the motherboard of my sony VAIO VGN-AR770U laptop.
The screen has certain artifact-lines, and the laptop shuts down itself abruptly often. Sony’s hardware diagnostic detected video error, I believe the GeForce 8600M GT is dying, which I am trying to replace. All people I ran into, told me it can’t be done.
Interesting enough, I found sony made a external dock with AMD video graphics inside + blu ray player-VGP-PRZ20A, Sony said it’s for certain sony laptops ONLY.
I went ahead bought it from ebay, but I have problem getting it detected after drivers installed.
My thinking is:
Either the drivers or the my laptop’s BIOS are designed to block it from detecting/allowing.
And if I can unlock/modify the existing drivers or unlock/modify the BIOS then allowing me to disable the existing defected Nvidia graphics card and allow the VGP-PRZ20A to work, then my “mission” will be possible.
I looked the laptops BIOS advance menu section, seems to me Sony is not even let me get to the video card section, no such option available.
2 things that are worth to note: Original OS was Vista Ultimate 32 bits, now running windows 7 Pro 64 bits, clean installation; the device manager states “standard VGA graphics adapter” in Display section, ie, graphics card, meaning unable to detect the dying Nvidia as well, the original driver 32 bits does not work with 64bits OS, or the Nvidia it’s own defects.
I am wondering, does any Pro(s) here ever modified that part of BIOS or driver in the past, so that it is accessible?
Thank you in advance,
Here are some info:
