Otherwise it is definitely CAPS replacement time. I will probably go for those ESR CAPS since they seem ideally suited for power supply applications.

It could be a cold solder joint because once heat is applied everything starts working.

Are you still on your original 3.6V MB battery? If so, it might be time to open it up for a replacement. With the battery replace, it's also the ideal time to up the internal 256MB DIMM to a 1GB and max your Luxo baby out if you have not done so already. If you have never opened it before, have some compressed air standing by. You probably have enough dust accumulation for building your own dust hamster as I did. Also, watch for the very tightly sticking motherboard. If mine was like that then chances are that yours is too. The original Apple (foxcon?) paste apparently becomes evermore gluelike with age.

Nope, I replaced the battery along with the HDD earlier this year (upgraded to a SATA SDD with and adapter). Upgraded the internal DIMM with a 1GB I pulled from an older HP tower, although the external SODIMM is a 512MB upgraded by the original owner. When I opened it up, I had very little dust and and no problems with the thermal paste. Of course I removed and reinstalled the thermal paste for optimum cooling while I was in there.
