SMD capacitor replacement

[Sofian75]

When you don't have a schematic and you want to replace a burned capacitor (on a laptop), other than matching the size, should you go for the highest capacitance possible or the lowest?
Could a different capacitance than the original be worse than not replacing it at all?

Thanks

you should look at what it connects to and then look at similar schematics for ideas

In a laptop a good portion of the caps will be filtering capacitors, so there should be very little in pF range. Since mobos often have duplicate caps on the same voltage rail, you can get a pretty good approximation about its capacity range by looking at the others.
