This sounds pretty bad:

I just hope that these defective Nvidia chips do not infect the new ThinkPads.

Here's some news on the subject.

 

Dell BIOS update

 

Needless to say, BIOS update won't solve the real issue... it just makes it so that break downs appear later with the expense of decreased battery life and increased fan noise.

 

I just hope that nVidia comes clean soon and reveals exactly what products are defective and starts replacing those products.

I'm interested to see if the Thinkpad T61p is affected as well.  As best as I know the graphics card in there is the same as the Dell 1530's except it's the workstation/CAD oriented version.

 

My T61p is affected by the 2dimm crash issue and there's a long thread in these forums that supplies a solution.  However, recently I've been experiencing graphic issue not related to using 2dimms. 

 

These two issues sound like they could be related.  The 2 dimm issue was caused by the motherboard not being able to handle certain voltages from the graphics card.  And this new issue seems to be an issue with the graphics card heat fluctuations.

webdtc,

 

The word on the Internet is that all nVidia G84 and G86s are defective - altough nVidia won't comment on this matter. The core of the issue lies in the packaging materials of the chips. This makes the GPUs fail under heat stress. Symptoms of GPU failure are horizontal lines and random symbols appearing on the screen.

 

I'm afraid that T61p and T61 are likely to be affected as well. I myself specifically opted for discrete graphics in order to get a better resolution on my new T61 14''. :(

GPU failures

2008-07-29, 7:19 AM
i've been reading about GeForce Go 8 series failures on laptops to the point where other OEMs that stock laptops with these GPUs are issuing BIOS updates to slow GPU failure.  I just ordered an Ideapad Y510 77582EU yesterday so i'm wondering if it is affected by this problem.  To backup my claims, here are the Dell and HP pages and news stories i've read about this problem http://blogs.zdnet.com/hardware/?p=2182 http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&docname=c01087277&dlc=en http://www.theinquirer.net/gb/inquirer/news/2008/07/07/nvidia-meltdown-blame-game http://www.theinquirer.net/gb/inquirer/news/2008/07/07/nvidia-meltdown-blame-game http://direct2dell.com/one2one/archive/2008/07/25/nvidia-gpu-update-for-dell-laptop-owners.aspx .

T61p - Quadro FX 570 - in trouble?

2008-07-31, 6:12 AM

I really wish the companies felt a little more responsible about the whole nvidia gpu issue... The fx 570 has the G84 so it might be affected. Recently, a bios update was listed as 'critical' on think vantage updates... so I'm guessing this might mean bad news for the T61p cards. But after installing it, I haven't really noticed any difference... except my lowest temp observation of 50C in the AC room. but they seem to be fluctuating more than before... And when I checked version of the card in device manager, it was listed as rev A1... there's a rev A2 also around for the 8600m GT cards... so one of these versions might be affected.

 

To be honest, I'd be happy enough if the thinkpad lasted me till nov 09. I got it only in june... i need it for college. My temps at idle are around 56-58C in an air conditioned room in India. Last night they went up to 68 when I was on battery before they came down to 58 by itself when i connected power (on video playback power preset). Are these fluctuations ok? cos i've heard that these heat cycles are the main issue more than high temps. The other day running trackmania for about 45 minutes temps went up to 86 at room temp of 34C... and about 76 in the air conditioned room... I need the laptop mainly for maya and studio tools next year... So am I looking to facing a lot of trouble or sending it for repairs?

PS: PLEASE NOTE that I use CPUID HWmonitor for measuring my temps, so let there be no confusion by listing tpfancontrol temps which are 12C lower for the GPU...
