T530 Claims Wrong Powersupply

Hi!

Since September 2014, I'm using a T530, running Kubuntu 14.04 LTS on it.
Everything (which I need) is running fine.

This morning, I got a message on booting which I've never seen before:
Before it showed the grub menu, the system claimed that the power supply 
had a lower wattage than expected, and required that I hit Esc to continue.

I did hit Esc, the machine displayed the grub menu, then booted, and I 
could use it without issues.

I later tried to reproduce the issue but failed: The system behaved 
normal and did not (yet) show such a message again.

All the time, the power supply was the original one, which had never 
shown such an effect before.
The power supply is labeled 20 V, 3.25 A, so it is a 65 W one;
CPU is Intel i5-3230M @ 2.6 GHz, 2 cores + hyperthread;
graphics is the CPU-integrated only ("Core processor Graphics Controller").

Checking Google, this is typically discussed related with a "power 
manager" which I assume to be some Windows component. This is definitely 
not involved here, the machine is Linux-only. Also, the message appeared 
before the grub menu.

Should I be concerned, or just ignore this as a once-only thing?

Regards and thanks for all hints,
Jörg
