So I started up my laptop today and was greeted with the following message (not a direct quote):

The type of the AC adapter cannot be determined. This may interfere with your 
computer's performance. Try unplugging the AC adapter and then plugging it 
back in, thanks.

The problem was that I hadn't fully secured the plug into the back of the computer. However, I was a little taken aback when a message from BIOS said, "thanks."

Is this normal? Any chance the message was illegitimate (virus)?

Probably wasn't written by a native English speaker. – Shinrai Nov 11 '11 at 23:11
what sort of laptop? – Journeyman Geek Nov 11 '11 at 23:12
@journeymanGeek Dell Inspiron N7010 – Josh Nov 11 '11 at 23:24
Yep, your AC adapter has a virus. – Daniel R Hicks Nov 11 '11 at 23:44
I like it when ROM coders write polite messages. It's so rare that it's wonderful, especially when it looks like they're struggling a little bit with the English language. =) – Randolf Richardson Nov 12 '11 at 1:00

The Dell AC Adapters have a specific module which communicates with the motherboard in order to verify you are using a "real" Dell Adapter.

When you are using a non-Dell adapter, or when your adapter has its chip toasted, or when your motherboard has its chip toasted, or when your adapter is loosely connected you get this message. The consequence is that your laptop is powered but the battery will not charge.

I understand that, but isn't it a little odd that it uses the wording, "thanks." ? – Josh Nov 11 '11 at 23:23
It's less odd than a BIOS that says "Please to be prepare for updating of BIOS flash", which is verbatim one I've seen before. :) Practically speaking, most of these things are written by Asian engineers who don't speak very good English. You're being paranoid. – Shinrai Nov 11 '11 at 23:42
My favourite is from a Phoenix BIOS on an XT computer (8088 CPU) in the 1980s that appeared when there was no keyboard connected; it went something like this: Keyboard not installed. Press F2 to continue. – Randolf Richardson Nov 12 '11 at 1:03
thats common, what they mean is plug in a keyboard and press f2. Modern systems still do this if you have halt on keyboard error turned on – Journeyman Geek Nov 12 '11 at 5:35
but isn't it a little odd that it uses the wording, "thanks."? Sadly yes; we have become accustomed to terseness in technology (to the point that to us devs, it actually gets to feel “correct” to speak frankly). most of these things are written by Asian engineers who don't speak very good English. I’ve never understood that; it’s not like there are no fluent bilingual people in China, Japan, etc. Why cannot a company hire someone whose sole job it is to be a proof-reader‽ o.O – Synetech Dec 1 '12 at 23:25
