LaTeXiT and Pages; fixing misaligned equations

Monday, August 20th, 2007 |

This follow-up post shows how to fix the placement of inline LaTeX equations placed in Pages.app by the LaTeXiT.app application on Mac OS X. This issue was highlighted in a comment by reader Fabien. By default, the image that has the latex equation will be embedded in the document slightly too high (as shown in the comparison below). That is to say that the baseline of the equation doesn’t match the baseline of the rest of the text.

Update on the cause of random shut downs

Friday, October 20th, 2006 |

Jason Siebert, aka Sieb (thatsiebguy), who took the photo of the melted insulation featured on our demystified post points out that the shut downs may be caused NOT by an electrical short circuit problem but rather by the high levels of heat that the sensor cables are exposed to. Heat increases the resistance of the electric sensor cable and this results in a decrease in the current through the cable which in turns lead to altering the signal sent by the heat sensor (thermistor). If this signal indicates a high enough temperature, it is possible that the MacBook just shuts itself down to prevent any damage to the processor.

Random Shut Downs Demystified!

Friday, October 20th, 2006 |

Thanks to some pictures of the MacBook heatsink on Flickr, the cause of random shutdowns in the 13″ MacBooks is now clearer! As previously thought, it is indeed an insulation issue. Here’s a close up of a melted heat sensor cable:

The area where the cable insulation melts actually houses a pair of cables and it is suspected that this is where the short circuit triggering a shut down occurs (when those two cables make electrical contact).
