Structurally, capacitors consist of electrodes separated by a dielectric, connecting leads, and housing; deterioration of any of these may cause parameter shifts or failure. Shorted failures and leakage due to increase of parallel parasitic resistance are the most common failure modes of capacitors, followed by open failures.
Early and late 2011 models with a GPU; 15" & 17"; reportedly suffer from manufacturing problems leading to overheating, graphical problems, and eventually complete GPU and logic board failure. A similar but nonidentical problem affected iMac GPUs which were later recalled by Apple. [94]
The easiest way to tell if the unit is a Rev.2 is by looking at the CMD chip located on the logic board. The CMD chip on Rev. 1 logic boards is PCI646U2 and on Rev. 2 logic boards is 646U2-402. [33] Revision 2 350, 400, and 450 MHz units use the same motherboard as the first "Yikes" version of Power Mac G4 systems at 350 and 400 MHz ("Sawtooth ...
There were problems with batteries on some 2007 models not being read by the MacBook. This is caused by a logic board fault and not a fault with the battery. [citation needed] In February 2010, Apple announced a recall for MacBooks bought between 2006 and 2007 for hard drive issues. This is caused by heat and other problems. [citation needed]
An analog board is a circuit board that contains the majority of analog circuitry in certain Apple Macintosh computers. The analog board was one of two circuit boards within many early Macintosh computers, including the Macintosh 128K/512K/Plus, Macintosh SE series, and Macintosh Classic series. The analog board contained several capacitors, a ...
The new 512K model was nicknamed the "fat Mac". While functionally the same, as closed systems, the Macintosh and Macintosh 128K were technically two different computers, with the rebadged 128K containing a completely redesigned logic board to easily accommodate both 128 KB and 512 KB RAM configurations during manufacturing. Though the RAM was ...
The iMac G3, originally released as the iMac, is a series of Macintosh personal computers that Apple Computer sold from 1998 to 2003. The iMac was Apple's first major product release under CEO Steve Jobs following his return to the financially troubled company he co-founded. Jobs reorganized the company and simplified the product line.
