I think you should read the whole thing, because Lamo already explained how it is done. I have tried the burn in technic what Lamo suggested and I it worked. The subject here is when you can not use a regular adapter, because it will shut itself of to protect the components and itself I think. You have to find where is the short and that is the fastest way. I recommend to read Lamo's post #13 again and like he says be very careful.

Hello i am having the same problem, what i would like to know is what part of the board did you come across these capacitors ? underside of motherboard? or the top of the board? where are they near? which compacitors are they are they the small brown ones? or the black ones with the writing on? or the tanned ones which are kind of bigger? please can you tell me what part of the board please, and which one you removed i most have the same problem. but i wouldblike to know where they are on the board so i can test to see if it is them. thank you for your time

I have to say the same thing what I sad before. Read all the replays in this two pages especially the ones from Lamo. He is the one who showed and explained us the "burning method". I have done that method numerous times with success on different motherboard as well. At the beginning I strangled a little, but that is the fun. I can't tell you which capacitor it is, because it could be any and there is a lot of them. It could be on top or bottom just follow Lamos guide of burning method and it will show you which one is it.
Thanks a lot again to Lamo.

HMMM.. you have not answered my question, you say look at lamo. yet you say on the subject you found the capacitor. and all 3 look the same. i am not asking you to resolve my problem, i am asking you can you remember what part of the motherboard was the capacitor . surly you can remember that? top? bottom? location on the board? i will say again i am not asking you to resolve my problem. i just want to know from your own experience what part of the board did you find the capacitor. on the dell d800 motherboard. so where on the motherboard.?

i have no interest in what lamo done otherwise i would have asked him and yes i have read the board i just want to know where u found the dead capacitor on your board. what colour was it? small, big? bottom board top. near by cpu? near graphics? i just want to know that. that's all? so where on the motherboard did you find it? or did u find it at all?.
