If you live in the UK then you can find some replacements here.
Otherwise you can find them on ebay every now and then.
There is also a Canadian site that sells refurbished ones but I cannot remember the address at the moment.
Seeing as the motherboard is dead it might be worth investing in a new laptop and I would also suggest getting a notebook cooler for when using a laptop in bed to avoid this happening again in the future.
Well I got the new processor today (T5600). I am very happy to report that it in fact does work in a Acer Aspire 3690. I upgraded to the latest bios, v3.10.
Now the next question I used CPU-Z and I can only access 1 processor. One the front page it doesn't allow me to choose the processor. The drop down menu is not available for me to select. How do I know if both are working properly? When I do a system check it says T5600, 1.83 1.83, so I know the computer recognized them both. Is there a different program that I can use to to verify that both cores are working?
I see no reason why the 2nd core wouldn't be working but one way you could check is by running a wPrime 32 test and the T5600 should get around 50 seconds with 2 cores and around 90 seconds with just the single core. You can download it for free here.
I also believe Everest will show if both cores are working but I'm not at my home PC so I can't check that at the moment.
What are your idle temps like with the T5600? Notice any difference from before?

I just ran the test and it came back at 46.283 seconds. So I guess it is working just fine. How do I find out the idle temps of each core?
Here is the next problem I have just noticed, when the computer goes to "sleep" ie close the lid for more then 10 minutes. It locks up, I have to do a hard shut down and reboot. Is there some setting that I am missing or is there something I should change. I did have this problem with my M 520 but it was a once in a great while (maybe once a month). Since I have installed the new processor, about 24 hours. It has happened about 7 or 8 times.
What should I do? What information do you guys need to help me out?
I am using Vista Home Basic, What is happening is say when I am done using the computer, I usually just shut the lid. Now say I come back in 30 minutes to use it again. The power light is lit, but I can not get the screen to turn back on (wake up). I have tried typing key as well as touching the track pad, and mouse buttons, but it does not respond to anything. I just have to do a forced shut down by holding the power button and then restart the computer. Once it is running again, everything is fine until I let it sit and the computer "goes to sleep." Then I am back to a blank screen.
could you tell me that with my acer's specification i am able to upgrade it. thank you very much.
From you specs it looks like a i943 but could you tell me what the sticker on your RAM bay says (its located behind the access panel on the bottom of the laptop)? Then I can tell you exactly what you can upgrade it too.
Congratulations on your blazing fast Core 2 Duo laptop. I'm thrilled that the upgrade process worked for you, and that you are the proud owner of a rare Core 2 duo Aspire 3680. . So now we know that the C2D T5300 is a great addition to this "cheap" little laptop. Michacerboy if you could post some benchmarks, temps, or a new battery life estimates from vista that would be great. I guess that will come after using the laptop for 2-3 days. Just come back with any descriptions of your experience. . Hope everything is well!
EDIT: I just realized we got ours from the same ebay store that said the Core 2 Duo was a T5200. They both turned out to be T5300s. lol.
are you sure that t5200/5300 can be installed to acer 3680 w/ gml 490/493 calistoga? cause when you opened your laptop you did see the chipset was i493?
can you give me information on your acer 3680 laptop? mine are 3682, asia region w/ celeron 1.73Ghz, chipset 940/943 calistoga, bios v 1.3203.
