Last summer my macbook power supply overheated and died. common I here you all say :)
So I went to the junk shop here in Japan and bought the largest 19.5v brick of a power supply I could find
that could deliver some serious power !! I have an i7 15" so I think it needs 85watts
I found 1 x 19.5v 6.15AMPS for equivalant of about 2$
I ordered the magsafe cable ( not that cheap ! about 8$ ) , soldered , heat shrunk and it works very well ..
no massive heat and the mac reports ...
AC Charger Information:
Wattage (W): 60
Serial Number: 0x00d240b2
I dont believe thre mac power supply communicate with the laptop at all let alone detect how much power it can deliver.
The magsafe cable has 2 wires. power and ground , and yet it has a load of pins...
The Mac Store replaced my mac power charger , but I'm sticking with this one. it is bigger , but its actually
the same weight and I believe its a lot safer.
I showed the Mac genius's my modified power supply and said it was going to be overall more reliable and safer.
They looked horrified, like they had see a terrorist at work !
Anyway , I highly recommend this basic hack if your like me and have you computer crunching away routing 4 layer boards on hot summer days... save you mac charger for airports and fancy cafes..
buy a brick for every day use !!
PS.. don't blame me if you blow up you mac ! chose your brick wisely :)
