I've sold hundreds of T4x units and found this test to be very good in determining the GPU health:
http://freestone-group.com/video-card-stability-test.htm If a machine can take 1000 minutes (which is what I have set as a standard), the GPU is fine. Test the SouthBridge chip as well - anything that you plug in USB port and ends up showing as 1.1 instead of 2.0 will tell you that the chip in question needs re-balling. Good luck.

I'm not selling them here, per se, but I'm more interested in figuring out whether the BGA video (or any other) issues would bite me in the arse if I were to sell these. I'm just afraid I would be preparing a working laptop (after a long-enough dormant state) for resale, not find any flaws (especially with respect to video), advertise it as such, and then have the buyer reply saying there's no video. Are there any risks specific to the T4x Thinkpad I should be considering? _______________________________________________ Thinkpad mailing list [email protected] http://stderr.org/cgi-bin/mailman/listinfo/thinkpad _______________________________________________ Thinkpad mailing list [email protected] http://stderr.org/cgi-bin/mailman/listinfo/thinkpad
