Question I'm looking for specific part, though am not sure of what it is.

I'm fixing an old laptop (ASUS Q501L) and one of the, of what looks like a capacitor is dead. It is labeled "M36U" "15" "25 v". I've looked around for a while using those labels, though have not found anything like it.

Not a whole lot to give a sense of scale.

Probably a 5mm 15uF 25V SMD Electrolytic Capacitor

Something like this would work, just confirm the size:

I'll see if it works.
Thank you.
