2 is a coincidence, 3 is a pattern... and your problem is identical to mine, too, and happened just some days after mine did...
It seems to me, without wanting to be alarmist, that the T61p with the 570M gpu (or a batch of them) is failing with the same exact problem (1 long 2 short = GPU error) at the exact same time... scary thought, really.
Mine arrived at the lenovo repair center (it's still on warranty) on wednesday, and the status shows as "Repair complete, shipped to customer" as of yesterday. There is no tracking number or "Failing Element / part number" in the status page, tho. It hasn't arrived, either.
Do you know your planar card / motherboard part number? It would be interesting to know if it's the same as mine (42W7653). Were you affected by the problem shown at http://forum.lenovo.com/lnv/board/message?board.id=T_Series_Thinkpads&thread.id=30460&view=by_date_ascending&page=1 ?
And once Mark_Lenovo reads this, Mark, do you need any info? (serial number for the laptop, easyserv reference, etc?)
EDIT/UPDATE:
I called the EasyServ warranty customer support to ask if they had any additional info not in the website, and as a matter of fact they do. The (very, very helpful and nice) man on the phone told me that the motherboard had been replaced and the laptop was due to arrive today, and he gave the UPS tracking number for it, which indeed says it's scheduled to arrive here today, at some point.
Once it's here I'll update with information about the actual repair and the part number of the new motherboard, etc.
To be honest I'm more than pleasantly surprised about the service: the box for shipping my laptop arrived on wednesday, it was picked up that very same day, the laptop was repaired on thursday and arrives to me today, friday. If the laptop works as expected, this is a 10 out of 10 for lenovo customer support, at least for me.
I'm less-than-happy about the quality of the product, of course, but at least I got the 3-year warranty so lenovo paid for everything.
