45 Watt vs 65 Watt Power Adapter

Hi George,

Yes, they're interchangeable. Apple doesn't sell the 45w adapter now, only the 65w.

You're welcome.

They are not interchangeable. The wattage is different and your computer will run very hot - its like having a lamp that says use only 50 watt bulbs and you do a 75 watt bulb and eventually the thing shorts out.

I need a new 45 W power adaptor and Apple told me the 65 Watt works. The reviews on the apple site of this product are terrible - I think about 1 1/2 stars because its running hot and other problems.

After calling Apple several times and being reassured the 65 Watt would work on the iBook I have, I found out its a lie. They know the 45W is no longer available so they say the 65W is ok. It isn't.

Eventually I found someone at Apple who admitted even he had the problem and sent me to www.powerbookguy.com to order the 45W.

Beware!

iBook G4 Mac OS X (10.0.x)

Your analogy is incorrect. In this situation it is more like having a car that can go 120 mph but you only need to go 65 mph. There is extra ability but it does no harm. In fact having the extra rating will mean that the charger runs cooler than the original one.

I had to replace my 45w adapter and was told by Apple that a 65w one would work. Since using it, the battery icon has been slowly reducing in percentage. At first it was around 57% and although I only use the computer when connected to the mains, it now sits at 1% where it has remained for the last several days. I don't want to buy a new battery if the same thing will happen and I have noticed thatb the undrside of my laptop is getting very warm.
Any advice is appreciated
