Hi there, today I was forced into a corner (figuratively) as I had no choice but to buy a new power adapter for my 2.4GHz Intel Core 2 Duo Macbook (think it's 2007) because my old "T" style power adapter had gone kaput. I didn't want to shell out £50 on a new one but I needed to get on, so I went for it. So I've been using it for a couple of hours and it is extremely hot, I perhaps wouldn't have noticed so soon if i hadn't read the negative reviews on the apple store's website (it only has 2 stars), but looking at the transformer on the adapter, the only difference i can really see is that instead of it being Samsung (like the old one) it is Delta? Question is, is it worth seeking a refund (how likely is it I will get £50 back within 14 days?) and ordering a new T-style one from amazon or ebay? Or is this heat nothing to worry about? Even the magsafe head itself is now metal and this is getting hot. I can't believe Apple have the audacity to sell something for so much money and it get such low reviews (but it seems at the moment it deserves them). Rant over. I'd appreciate any answers/opinions. UPDATE: Since reaching 100%, it has cooled down massively, thank goodness.
