Editing IBook (section)

== Quality issues ==
Display issues with the iBook line were caused by a notoriously problematic graphics chip, which could have issues with the heatsink or the [[Ball grid array|BGA]] soldering work done at the factory. This would manifest in symptoms such as system lockups (as the graphics chip [[Hang (computing)|hangs]] from reaching the thermal limit), or visible graphical artifacts appearing on the screen (from the graphics chip failing).<ref>{{Cite web|title=SOLVED: iBook Freezes – iBook G4 12" 800 MHz-1.2 GHz|url=https://www.ifixit.com/Answers/View/560/iBook+Freezes|access-date=December 22, 2020|website=iFixit|date=November 15, 2009 |language=en|archive-date=March 2, 2021|archive-url=https://web.archive.org/web/20210302201611/https://www.ifixit.com/Answers/View/560/iBook+Freezes|url-status=live}}</ref>

Apple initiated the "iBook Logic Board Repair Extension Program" in January 2004, which covered the expense of repairing display problems of iBook G3 models for three years.<ref>{{Cite web |url=https://www.apple.com/support/ibook/service/ |title=— ''Expanded iBook Logic Board Repair Extension Program'' FAQ |publisher=Apple.com |access-date=September 4, 2018 |archive-date=March 11, 2014 |archive-url=https://web.archive.org/web/20140311224504/https://www.apple.com/support/ibook/service/ |url-status=live }}</ref> In June 2004, the Repair Extension Program was expanded to cover all White G3 iBooks.<ref>{{Cite web |url=https://www.apple.com/support/ibook/faq/ |title=— ''Expanded iBook Logic Board Repair Extension Program'' FAQ |publisher=Apple.com |access-date=September 4, 2018 |archive-date=June 16, 2012 |archive-url=https://web.archive.org/web/20120616074911/http://www.apple.com/support/ibook/faq/ |url-status=live }}</ref><ref>''iBook Logic Board Repair Extension Program Expanded to All White G3 iBooks'', announcement dated late June 2004, found in web archives of Apple support forums.</ref>

Early models of the iBook G4 also suffered from display problems similar to those of the iBook G3, but were not covered by the repair extension program.<ref>{{Cite web|date=March 28, 2008|title=How to fix a broken G4 iBook logic board problem|url=https://www.macintoshhowto.com/hardware/how-do-i-get-my-broken-g4-ibook-fixed.html|access-date=December 22, 2020|website=Macintosh How To|archive-date=December 14, 2020|archive-url=https://web.archive.org/web/20201214185450/https://www.macintoshhowto.com/hardware/how-do-i-get-my-broken-g4-ibook-fixed.html|url-status=live}}</ref> Owners of iBooks that required expensive repairs for these problems submitted new class action lawsuits in December 2006.{{Citation needed|date=May 2015}}

On May 2, 2007, the Danish Consumer Board published an extensive 3rd party report<ref>{{Cite web|url=http://www.forbrug.dk/presse/nyheder/pressekit/ibookg4/lab-report/ |title=iBook G4 Logic Board issue report made under the authority of the Danish Consumer Board |url-status=dead |archive-url=https://web.archive.org/web/20071014021213/http://www.forbrug.dk/presse/nyheder/pressekit/ibookg4/lab-report/ |archive-date=October 14, 2007 }}</ref><ref>{{Cite web |url=http://www.theinquirer.net/en/inquirer/news/2007/05/04/danes-prove-apple-ibook-g4-has-a-defect |title=Danes prove Apple iBook G4 has a defect |work=[[The Inquirer]] |url-status=unfit |archive-url=https://web.archive.org/web/20071002070613/http://www.theinquirer.net/en/inquirer/news/2007/05/04/danes-prove-apple-ibook-g4-has-a-defect |archive-date=October 2, 2007}}</ref> concerning the Apple iBook G4 logic board issue. A press release<ref>{{Cite web|url=http://www.forbrug.dk/presse/nyheder/pressekit/ibookg4/ibook-g4-english/ |title=Press release about the iBook G4 logic board issue made by the Danish Consumer Board |url-status=dead |archive-url=https://web.archive.org/web/20070609111548/http://www.forbrug.dk/presse/nyheder/pressekit/ibookg4/ibook-g4-english/ |archive-date=June 9, 2007 }}</ref> referred to the global consequences that this could have for possible guarantee claims.

Some owners of the iBooks that experienced this flaw solved these issues temporarily through applying pressure to the heatsink or graphics chip, using a thin [[Shim (spacer)|metal shim]] placed between the heatsink and the graphics chip. This both pushed the heatsink and graphics chip together, bridging the thermal gap, and pushing the graphics chip against the motherboard, temporarily reheating the solder beads back together.<ref>{{Cite web|title=iBook G3 and G4 logic board problems technical aspect {{!}} Applefritter|url=https://www.applefritter.com/node/10193|access-date=December 22, 2020|website=www.applefritter.com|archive-date=November 28, 2020|archive-url=https://web.archive.org/web/20201128020740/https://www.applefritter.com/node/10193|url-status=live}}</ref>
