On my T201s, a lower-power adapter works just fine except that it causes
the machine to throttle the CPU unless there's a (working) battery.
So I suspect that the same would happen for your T530.

AFAIK it's a normal USB connector where the yellow color indicates "this
USB connector provides power even when the machine is turned off".
I'd be very surprised if you can power the T530 via this connector.
