Re: T61 Nvidia Quadro NVS 140M.. garbled display problem!

A couple things about that heatsink. There is an improved version that has three heatpipes. All the discrete 14.1 standard and 15.4 widescreens used the improved version but the 14.1 widescreen didn't switch until the very end of the production run. I believe I have one of them and if I can find it I'll get you the numbers, but since you already bought one I wouldn't change it, especially considering your numbers are good.

 

However I would recommend removing the thermal paste and using some Arctic Silver 5. It's not required, but I've seen a noticeable improvement using it and considering the risks, I'd do it. I also hope you removed the plastic film from the grey pad that cools your boards chipset.

 

Lastly, avoid unnecessary heat cycling.

Nah, not really anymore .... this horse has pretty much been beaten to death here and one other topic in this forum:

 

http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T61p-exhibiting-1-long-and-2-short-beep-and-black-screen/m-p/1249673#M69226

 

Read back through the link above and you'll see the boat sailed years ago regarding Lenovo doing anything about it for you.

 

Simplest solution is to buy a nice used T61p for $200 off eBay and just swap in your HDD (might as well upgrade to a T61p while you are at it as the HDD swap will work just fine between a T61 and a T61p).  This will not require a reinstall of your system or any new activation ..... just power and keep on working as if nothing happened (recommend you also do a Lenovo System Update once you are powered up).

 

Just try to get one with a 2008 build date (as listed on the bottom label next to the S/N) as close to 08/08 (Aug 2008) as possible like 08/07, 08/06, etc (July 2008, June 2008).   Then sell your old T61 for parts (about $75).

Re: T61 Nvidia Quadro NVS 140M.. garbled display problem!

Guess nvidia blowed up from my T61. First there was some garbage on screen. Next thing was randon BSOD's, and now it refuses to boot, just black screen when powering it up.... Checked out ebay and there are some motherboards with Intel graphics available with reasonable price, guess it would be better choise since i don't play with it, just browsing and some internet gaming. Is it possible to swap motherboards from Nvidia to Intel graphics? My T61 is 14.1" widescreen, 7663-CTO from 08/05 and processor is (if i remember right 1.8GHz T7100). I checked hardware manual and it says 41W1487 and 42W7866  are MB's with Intel graphics. Can i just change motherboard, and i guess heatsink would be different?

Yes, you can swap in an Intel board - as long as it originally came from a 14" widescreen T61 - you're all set. The heatsink can be re-used as well.

 

While you're at it, get a slightly faster/better CPU, they are quite inexpensive nowadays...

 

Good luck.

Cheers,

George

Been there, done that. I was surprised how easy it was to take T61 in pieces. All you need is small philips headed screwdriver and one flat screwdriver for connectors. Just make sure you have good quality screwdriver since some screws are really tight (glued?). And make sure to mark where all screws belong. I did not and now have few spare screws....  Thermal paste i used for heatsink was Nexus TMP-1000 as local store didn't have arctic silver. tpfancontrol gives me CPU temperature 43c when idle and it rises to somewhere 68-70c at full load. Motherboard was from ebay seller ms-comps and they delivered it from England to Finland in about week. 60€ was not too much to get T61 alive again...

Re: T61 Nvidia Quadro NVS 140M.. garbled display problem!

2014-02-06, 1:27 AM

I just wanted to share some experience here, no problems so far :knock knock:

 

I bought a T61 (6457-A88, 08/03, version with 1 PCMCIA slot left and mini Firewire on the back left side) 3 months ago, for about $100 here in Croatia which is crazy deal! =)

Seller was a student that bought it in 2008 and never had any problem with it. (it had 3 years warranty, expired in 2011)

 

The laptop is like the new one and original HDD (Seagate Momentus, 100GB 7200 RPM) had about 5500 working hours when I got it. Battery was dead, so I got 9 cell (Sanyo) genuine battery with 75% wear (last for about 1 hour) for $10 and an OEM 9 cell (Sony cells form software readings) for about $25 on eBay that lasts about 2 - 2.5 hours.

 

It has a Merom T7300 running on a Penryn board (42W7876), 3 GB of RAM, WXGA screen - but it also has a NVS 140M :)

 

I have changed a thermal paste on the chips (AC Ceramique 1, that I've been using for a years), installed RM Clock to undervolt the CPU (it rans happily on 800MHz/0.85V and 2.0 GHz/0.96 V). I also installed TPFanControl and keep running the fan on ~ 2500 RPM.

 

Temps are great, here is the SS from AIDA and TPFC: Link (room temperature is about 20°C right now)

 

 

 

When I cleaned it, I forgot to see the date from the GPU chip, but I believe that wouldn't mean that much, because the laptop is manufactured in March 2008. That drives me crazy for real :)

I can't know if my laptop will have a blank screen tomorrow, or maybe it would last for another 6 years.

 

I would upgrade it with some Penryn CPU, some gigs of RAM and SSD. WIthout knowing about that GPU - I would say it is bulletproof! :)

I wouldn't loose any sleep over the gpu chip and it's likelyhood to fail or not, just take good care of it, keep the cooling system clean and most important...

 

Avooid unnecessary heat/cool cycling

 

I recommend you disable "standby" so it always remains at operating temps and if possible turn it on in the morning and off in the evening, avoid unnecessary on/off cycles, or you can run it 24/7 which will greatly reduce the stress on the chip.

 

Over all it looks like perhaps 1% or less of these units built prior to august 2008 have failed, but many people who buy laptops and boards have units that have already failed and had repairs attempted and are doomed to fail again, but since you got yours from the original owner yours is unlikely to have had the gpu tampered with. 

 

I'd recommend getting a T8100 gpu, they are very cheap and will run cooler than your cpu. They are one of the most underrated cpu chips in this series and you can increase the performance by 9% using throttlestop and middleton bios with dual IDA mode enabled, and even with the additonal speed it will run cooler thant your merom chip.

Thanks for your reply TuuS, you've been very helpful to a lot of people on many forums :)

 

I already contacted a guy who is a pro in a chip reballing here (he has several professional reball/reflow stations), just to ask for "in the case...". He confirmed me that he can provide a new chip from "his channels" and reball the chip with new BGA balls, but whe did not tell me the price. (I presume it would be about $100 with the service)

 

About the upgrade, I was considering T9xx CPU and some SSD for the start, because this HDD is so slow! :)

 

Oh, I forgot to mention a problem with the palm rest. My bottom right corner is cracked (from the prevoius owner), because it's so tight when it's placed. I should also buy another one. (mine does not have FP sensor)

 

Do you know maybe is it compatible with any other series? (I know that R61 is compatible, but I don't want R-series on my T :D :D )

No, the R series palmrests won't fit. The R series has a different frame and other than one specific model which is the 14.1 widescreen with firewire, in which case the boards are interchangeable, as are the lids, but the rest is not. 

 

I recommend you avoid all reballing and reflowing services. The "new" nvidia chips are only manufactured as needed and only when required to do so by OEM contracts for companies like Lenovo. The rest on the market are mostly fake chip that have had the numbers polished off and re-etched. If you do a google search on the terms "fake chips" and "china" you can read more about this but I know of reputable reballing companies that have been scammed by these fake chips that are usually pulled from salvaged equipment and sold as new. Most of the major reballers won't do a nVidia chip for this reason and many who will often just reflow the board with the original chip, the heat will usually cause the fractured circuits to contact and result in a working board...  but only for a matter of days/weeks, perhaps months, but they all fail again. 

 

The only way to properly fix the laptop is to replace the board with either an 08/08 board (they are rare and will probably cost more than your laptop), an Intel board, or an original board like yours that you can confirm has never been tampered with. 

 

Some brief history on GPU problems. On prior models there were gpu failures cause by the boards flexing and the BGA solder joints would crack. Reflowing or reballing was a viable solution and fixed the problem, but then came the nVidia chips which failed not from BGA problems, but internal chip faults, but not knowing this the repair shops assumed it was the same issue so they started reflowing and reballing the boards only to quickly find they had a 100% failure rate, so the reputable ones stopped doing them, but at the same time scammers popped up who were willing to reflow boards and laptops knowing that it was very likely it would last for 30days, just long enough that a buyer from an online auction site would have no recourse, and they get away with this because buyers are generally forgiving if the seller agrees to replace or repair, so if the first board doesn't last 30 days, the second may, and eventually it too will fail but by then there is nothing the buyer can do. Of all the members who have contacted me looking for an 08/08 board, many have been down this road and have found after the futile effort to save some money that they not only wasted money, but also time, and the work to replace boards multiple times and deal with RMA proceedures to only end up again with a dead laptop. 

 

If your laptop really does have an original "virgin" board in it, even if it's one of the "at risk" dates, I'd just use it and follow the precautions I advised and odds are it will last for years, but if it does fail I would avoid having it reballed or reflowed. 

 

At least that's my opinion.

 

ps. I have some palmrests, with and without FPR if you're interested you can send me a PM, but the shipping cost may be an issue.
