T61 nvidia nvs140m production date

#1 Post by lincolnor » Sat Dec 03, 2016 11:55 am

I have pick up a T61 nvidia nvs140m with 08/08 ( bottom of laptop). Is there any other labels on the laptop to confirm the production date?

I have install the nvidia driver and it look great on the WSXGA+ (1680×1050) screen.

Thanks.

Does the MTM type number on the label on the bottom match that in BIOS? If so there's a good chance the MB have not been replaced. You could check the FRU on the MB and see if it's a Peryn board. Having said that, these machines are over 8 years old and still runs good. They've more than out live their expected life expectancy and can be had for a song. Use it, enjoy it and don't worry to much about it.

With the MTM and serial # you should be able to go on Lenovo and check the production date. I think the check warranty status is the best way. You can also verify the installed screen type this way by drilling down to replacement parts.

Or check the production-date on the nVidia GPU-chip.
Check the picture on my website: http://theboardroom.info/t61motherboard.html
The 1021A2 indicates: Year 2010, week 21

That 0815 is 2008, week 15 (7-11 April).
AFAIK not yet a good production date.

You can help minimize potential failure risk by applying the undervolted (and overclocked!) GPU BIOS mod which helps reduce heat output - and also running a slightly more aggressive fan setting in TPFanControl.

My FrankenPad has a GPU date code of mid-late 2007 and is obviously within the defect period, but it has shown no signs of failure under any conditions. I've seen some make a remark, which I honestly agree with. In general, the gist is that with these machines now approaching 10 years old, those with nVidia chips which were "destined" to fail - safe date or not (and yes, I've seen safe date chipped systems die a GPU death as well) - essentially already have, and that the greatest likelihood of failure now stems from the sheer age of the units rather than a specific design flaw.

I ran my stock as a rock NVS140M mobo that wasn't Penryn compatible every day for like 5 or 6 years, when I managed to score a NIB reissue motherboard. So it's got the 'upgraded' NVS140M, upgraded in that it doesn't use the faulty solder.

Replace the stock thermal gunk, insure you keep the fan dust free(I dust mine at least once a month), and don't put it on surfaces that are bad for cooling(aka blankets, etc.)
