Hello folks, I seem to have a lot of trouble when it comes to distinguishing markings on SMD components especially when it comes to the question of whether it is a 1 or an I. for example, I see components marked NI. It looks just like that. However, I cannot tell if that "I" might be a number one instead. Is there a rule of thumb that manufacturers use when using these characters? Attached is an example. This is just one example out of many I come across but it's a good illustration of my point. I appreciate any input.... -

Had someone drop off a laptop in which they were upgrading the ram but forgot to unplug the battery.
Looks like the ram RFI shield shorted a rail going to or coming from a Silergy IC which blasted a component off the board. I'm going to assume it was a cap but really have no way to know for sure since this board schematic doesn't appear to be in the wild yet.
I'm trying to identify the IC model now but it doesn't appear to match any of the Silergy codes from https://www.badcaps.net/forum/troubl...-tablets-and-m...
