Réponse à : « Replace HDD with Hybrid without fan issue »Just replaced the drive in a 3.1GHz i5 27” Mid 2011 with a bad 1TB Seagate drive. Thought Apple had a replacement program, but they told my customer NO. (they say a lot of things lately). Ok so when I took it apart there was no thermal sensor on the HD, nor a cable. SO I put in a Black WD 2TB. When reassembled, high fan noise on the middle HD fan. So I put on a fan regulation program, dialed down the HD speed and all is fine. Q - with no cable and no sensor… why did this happen?
Réponse à : « Intel 24" iMac 2.66 won't power on! »On the iMac I had, it was a 5A fuse that blew out on the Power Supply Board. It is a radial, 2 lead and rectangular black. Located near the AC line input wires. Apple recommended a new power supply :)
