In Sony Vaio PCG-7144M notebook is only one elyte capacitor - a small SMD cap that is d6.3 x 8 and looks like this - black print:
On the cap is this:
100
EFK.
8R6
The NTB is from 2008 and it looks like Panny FK cap:

...since the "j" is the voltage and in this case 6.3V, while E in the voltage table:
...looks like 25V to me.
The dot is mark about lead free product (I did not made it up).
And a 100uF 25V Panny FK do have the d6.3 x 7,7mm (I rounded the 8mm to something like that) dimensions also.
Therefore (except the unknown lot number) I would be inclined to believe that I got it right, but that of course awaits some approval
That is, because I do consider Panny caps as good ones and the NTB behawe like it have all the bad caps inside: https://www.badcaps.net/forum/showthread.php?p=373108
And that lead to my disbelief about what this is... not to mention that the NTB power cord claims to be 19,5V DC, witch corelate well with the 25V capacitance...
