Hi all,
I have a laptop that I am trying to fix. The problem is a blown capacitor on the power regulator board. There are no markings on it anywhere. I have measured a similar cap on the board at 10uF so im using this as a base for replacement. However, I am unsure what type of cap to replace it with, it looks like a small chip about the size of an 8pin IC. Looks like a surface mount tantalum and being a computer circuit i would assume it is, but tantalums are polarised and there are no marks on the old cap or the board as to a + or - side (other caps like electros on the board are marked on the + side). It appears the only caps available upto this size in, and in a small enough physical size are electros and tantalums, both of which are polarised. I have already tried a bipolar electro and that didnt work.
Can anyone offer any help, can i do much further damage trial and error fitting a tantalum, other than blowing the new cap if its round the wrong way
Thanks in advance
