Looks to me like a solid tantalum capacitor.

If I read those codes correctly as
A8
JR

It might be a 100 uF, 6.3V cap made April 2014 (Vishay). That is, A8 = 100 uF; J= 6.3V; and R = April, 2014. If you can measure it to get the actual case size, that would help confirm that identification.

Edit: That cap does not look like it failed electronically, so I would also recommend testing it with a capacitance tester.

i am having issues with one notebook motherboard and am trying blind tryouts with the bigger capacitors on the board.

what about nes ej8?

Notebooks, particularly those made after 2014 are quite sophisticated. I don't think blindly removing and replacing all the "bigger" capacitors on the board will be a productive way to troubleshoot it.

how do you analyze the markings, what about the 100 efk 6v1?

i see short D-S in 6690as without desoldering the ic. The element should by faulty, right?

thanks
