T61p Nvidia problems...

2012-11-10, 8:27 AM

Hi guys

 

I have 3 of these laptops - one has died already - it won't charge or power on by AC only - only putting a pre-charged battery in will allow it to boot and run until the battery dies then nada

 

the other 2 are running OK but having been reading about the Nvidia horror show I am now very concerned about the remaining 2 laptops

 

the warranties expired about 11 months ago and i'm wondering what my options are for getting the boards swapped out - preferably to Intel GPU's

 

thanks

 

Solved! See the solution

The actual failure rate is low, there were millions of these units made, and even over 5 years later it's believed less then 1% have failed. The bigest problem is are the huge amount of "repaired" boards being sold. Once the chip fails, you can't fix it. There are ways to make them work again, but they never last. If you have original systems that never failed, it's likely they will continue to work, but if you do need an intel board and can't find one in your location, I can get them. They are very uncommon in the 15.4" models, especially if you have a Penryn CPU. 

 

As for your system that will only boot off of the battery, that's not a GPU issue, sounds like a bad power circuit on your board. Try removing the battery and cycling the power buttion ten times, holding a few seconds each time, then 30 seconds on the last, then connect ac power and see if it will boot.

TuuS, in my short time researching this issue, I'd like to thank you for all the valuable information you've posted. It seems the best approach is to find a replacement intel board for my T61p. Can you provide some advise on how this can be done, and the approximate cost? I've since purchased a wide screen T520 which just makes me miss the display I had on the T61. If there's any additional information you require that further defines the exact model I have, please let me know and I'll be happy to provide it. Thank you again.

I sent you a PM with the info I need. There are still a few Intel boards available, even the rare ones that support the Penryn cpu chips.

My beloved T61 w/ nvidia gave out after almost 5 years of daily heavy usage. From video editing to acting as a presentation source for video projection, to standard office tasks. It performed without a hiccup, except when I spilled a cup of coffee on it & some of the keys stopped working (separate, unrelated issue to the nvidia failure)
It quit working two days after I upgraded to a T530. Coincidence? Seems ironic.
After perusing the forums here & finding out about the nvidia chip issue, it made sense to me to try and fix it.
User Tuus and I sent a few private messages back and forth and I decided to replace the mainboard with a non-nvidia board, thinking Intel graphics would be fine for the T61s intended future as a basic office machine: no editing or video projection.
Tuus sent the replacement board quickly and well packaged.
Installation was very straightforward using the T61 hardware manual available through this website.
Other than the board, my only other expenses were a new cooling fan, also purchased through Tuus, some thermal paste and a grounding wrist strap.
If you are at all mechanically inclined and can spare some coin, I would consider saving your T61 to be a worthwhile investment.

Mine gave out after 4 years. I had used it daily for software development constantly moving it from my house to a customer site and it worked flawlessly. When I upgraded to a W520 I gave my laptop to my son to use who promptly installed Minecraft. Minecraft, being written in Java, is cpu hog and cooling fans would spin up to max almost immediately when he started the game. Well after 6 months of torture the GPU finally gave up the ghost. It makes me wonder if there could have been some preventative measure taken of applying new thermal grease and just a thorough cleaning deep inside.

 

Anyway I too contact Tuus and he sent me the same configuration (new mainboard without the nvidia chip). I was a bit intimidated at first having never completely dissembled a laptop before but I followed this video for the T60p and it was almost identical to the T61p. The only other thing that I did was take pictures of each screw I removed next to the hole it came from along the way so that I knew which screw went back into which hole when I reassembled it. I also used a series of labeled ziplock baggies to keep them all organized during the steps of disassembly. Probably overkill but it made it allot easier to put back together again. Overall it probably took me 3 to 4 hours but that was with allot distractions. If I had to do it again it would certainly take well under an hour.

 

I can't thank Tuus enough for his help. Lenovo certainly owes him a great deal of gratitude for helping so many of their customers.

 

Thanks Tuus!

Thanks guys, I'm glad my efforts were appriciated, but I want to stress the important thing here is that these laptops can be fixed. Most members here who fixed them have never done a board swap before, and they walked away not only will a working laptop, but also gained some skills and I'm sure no matter what the future holds for this, or any future thinkpads, they will never look at them as a disposeable piece of equipment again. I've been buying thinkpads almost exclusively since before IBM coined the name, and even before the world wide web was born, I traded parts on compuserve, then before that on various BBS services. Anytime you had a thinkpad die it was always an easy fix, any other laptop would pretty much hopeless.

 

Thanks for sharing, and I'm honored to have been able to help you.  :)

OK, I get it, the competition to see who's older! My first ThinkPad was 700C. The lineage after that was 760ED, A21p, T43p, T61p and finally my current W520. Somewhere in there I also owned a Dell Inspiron 9100. And before the Thinkpad line came out I also had a Compaq Portable II, Compaq SLT and an IBM P70. Prior to PC's I worked on a PDP 11/40 (high school with RSTS/E), 11/70 (college with RSTS/E), 11/34 with GT62 raster scan tube (college with RT-11), KIM-1 6502 (college), IBM 360/40 at EDS (all punch cards including the OS!), IBM 7040 at EDS and the Wang 2200 at the HIG. As a kid I used to go to the local Heathkit store but my paper route money wasn't nearly enough to buy  one of their computers. For fun along the way I had a TI 99/4a and a C64. I used various BBS services, Prodigy and Compuserve.

lol, I had a couple of the ibm ps2 P70 luggable models too, still have one I think, it was in the middle of being upgraded to scsi harddrive after I had upgraded the cpu and ram, then just lost interest in the project and packed it into boxes. I also had a couple ps2 L40sx, perhaps the first ibm notebook. I don't remember every model I've owned since, but I did just dig out my 755CX and sold it to a collector, still working after a decade of storage. My first computer was a tandy trs-80, first model, but it didn't interest me much, it wasn't until the 386 chip came out that they begun to be interesting.   No competition though, just interesting conversation :)

Actually the first IBM "Think pad" predates the first ThinkPad by a few decades. From my collection:

Sadly the part numbers are no longer in IBM's system so I can't order refills.
