Wouldnt of happened if it was a MacBook
Im just saying...
^word.
Completely untrue. Coincidentally, my friend who is a graphic designer, his power supply on his Macbook died last week. And guess what happened - it fucked something up internally and fried his harddrive.
My harddrive is fine

Anyway, my laptop is running fine now.
Since logically it had to have been the battery, I bought another power supply, took the battery out, and am running it off mains only - and it works perfectly. So my cousin was right.
Now I'm about to phone the manufacturer to get another battery.
No big deal in the end.
