Hey guys,

I couldnt find another section that made me think of people that have knowledge about the delicate motherboard parts.

I just arrived back from spain, and wanted to boot my laptop.
When i booted it, i got the bios screen etc, but all of the sudden it started to smell reall bad, and a light smoke came out of my exhaust @ my CPU.

It scared the hell out of me and i went and opened my laptop.
This is what i found:

1 of those grey blocks where burn loose and dropped on the plastic cover of my laptop

Whats on the block: 9same as the one still there)
c(the c is very small) R36
J125-01

WHAT Should i do?
Should i try to solder it back on? or where can i get a new one? It seemed only that specific block near my CPU was damaged.

any help is welcomed!

You could try and soulder a new one on but the chances are its going to of messed up the whole board plus its also burnt the 2 little grey chips to the right of it and they will need replacing.

The question is, can you get a replacement board for a few £/$

The 2 chips at the right arent burnt, theyre just colored by the smoke oxidation. Looking up close they look perfectly fine.

And where can i get a replacement chip?

Does anyone actually know what it is that burnt? (the chip)

It's an inductor also called a choke. Something like this: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=SRP1040-R36MCT-ND

Clean up that board with some acetone or alcohol. Does look like one of the smaller mosfets has a burnt spot. They leave a little circle on top when they blow.

Found something that looks like it, also has the same dimensions.

(the case 12)

Yep, that's one. 48 amp one to. That's large then any of the R36's digi-key had.

so which one should i get?

0.360.9548HM72A-10R36LFTR ??? this one? :O

The datasheet has those size value, but i dont know what amps i need. Mind on helping me out pizza?

Does the brand matter?

EDIT: noticed, they dont ship it anymore

nvm, the one im looking for is: 10x10x4mm, 36UH

 

[PizzaMan]

didgi-key doesn't even carry them 10x10x4mm. Might have to go with 11.5x10x4

Ohh nice

how can i be sure its the right one? as in, volts etc?

it does kinda suck, that the VRM for my laptop blew up xD No power

So long as its a larger amp rating then the one before it, you'll be fine.
