T61 and prior T series ThinkPad Laptops

[#1]

Hi, I have T61. The screen is blurry. First I saw the error "Display driver stopped responding and has recovered."  in VISTA. I have completely removed vista and install the XP still my screen is blurry. Some times while booting I am not able to see anything. Any help would be greatly appreciated.

Probably the GPU failed.

Is it still in warranty? Call lenovo and have them replace the motherboard...

If you post your machine type/model (i.e.: 7661-xxx, info is on the bottom of your machine) you can determine if in fact you have a model with nVidia or Intel graphics. When you say you can hardly see the screen when booting: I have this to as I have specified dynamic brightness control in Power Manager. If you turn bright. control off next time you boot the screen will come display at the last brightness level you specified whil in Windows I think.....

Back to the original problem: fuzzyness. It sounds like once XP was installed the hardware specific display driver (either nVidia or Intel) was not installed and you may be in XP's VGA mode.

one more thought on the initial problem: if the display driver is not running at the native resolution (which depneds on which machine type/model you have) the display can appear blurry......

my system model is 7662-CTO. I  can say most of times(7 out of 10 times) i hardly see my screen while booting. Thanks for your suggestion. Any help would be greatly appreciated.

unfortunately a 7662-CTO is the generic machine type of a machine configued online to your specs and does not show the actual physical specs (i.e.: type of graphics) on the support web site.

What is the machine type in the BIOS?

if you have System Update installed you can also get the machine type in

C:\Program Files\Lenovo\System Update\egather\sysreco.XML. It is in the field

<ASC ID="System Model">7662xxx</ASC>
