Weird ignitiony thingo happening

[MGGT RAA]

How's it?

After my xr8 and I had a disagreement some weeks ago, yesterday I decided to give Her another chance but it seems she is now punishing me for it...

So the battery was flat as a word we're not allowed to say on here, so I whacked it on the charger which was all good, once that was done I hooked her back up, the Arial cycled like it usually does. Got in the car to kick her over,switched the ignition on the dash lit up but no roar, not even a click from the starter motor. Much annoy! 1 thing I noticed while turning the key, at the point where it should have turned over the digital display where the mileage is usually displayed everything cleared and it showed a 'T'.

WHY????

Is there some sort of fix for this?
Does the 't' stand for your starter motors knackered?
Should I push it off a tall bridge?
