Mac Forum / General / Portable Macs / August 2006life-expectancy of a Titanium PowerBook
Any ideas about the life-expectancy of a 2002 Titanium PowerBook which... (i) is always on (ii) always has the lid closed [using an external monitor] (iii) always uses an external Firewire drive and the internal drive is unmounted (iv) always keeps its internal temperature under 108F [according to Temperature Monitor Lite] Thanks, PaulN > Any ideas about the life-expectancy of a 2002 Titanium PowerBook which... > [quoted text clipped - 7 lines] > (iv) always keeps its internal temperature under 108F [according to > Temperature Monitor Lite] Temperature Monitor (Lite) will not run on a Titanium.

There are two different cases: • The computer uses a self-contained cooling control system. The hardware itself controls its own monitoring. No transfer of data from the sensor to the operating system is possible because there is no bus connection between the sensor and the actual computer. • The computer contains sensors accessible via a data bus, but cooling control is independent of Mac OS X. Apple does not provide any device drivers which would allow application programs to get data from the sensor. Only the firmware or a closed part of the operating system core has access to sensor data. In both cases, it is not possible to develop an application program which could read out sensor values. The following Macintosh systems are affected by this problem: • PowerBook G4 Titanium (all models) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ • eMac (all models) • iMac G4 (all models) • Mac mini (all PowerPC-based models) </snip>---------------------------------------------------------------- Florian Florian Zschocke <edv@zschocke-berlin.de> aszonygya: :> Florian Zschocke <edv@zschocke-berlin.de> aszonygya: :> :Temperature Monitor (Lite) will not run on a Titanium. :> :> It does.

Until the hardware gives out, or until you no longer find it useful? Hard drives wear out eventually but in most cases will last several years. Likewise the optical drive. The battery of course will go after a couple of years, maybe more depending on use, and will eventually become hard to replace. The screen will dim over time, and keyboards wear out, but since you're not using either then they don't matter. Same for the power plug-- but only if you unplug and replug it, which it sounds like you don't. The rest of the components... well, indefinitely, barring things like nasty power fluctuations and excessive dust in the vents. Any silicon chip will wear out eventually but once you've passed the initial burn-in phase they can easily go for decades.

Thanks for the good news. I forgot to add that, of course, I don't expect the battery to last and I meant the life-expectancy of the hardware. BTW, I am on my second battery. It acts like a UPS. /PaulN > > Any ideas about the life-expectancy of a 2002 Titanium PowerBook which... > [quoted text clipped - 13 lines] > chip will wear out eventually but once you've passed the initial burn-in > phase they can easily go for decades. TiBooks are IMMORTAL! As the first 'elemental' Mac, Apple made the command decision to make the hardware last forever (hard drives excepted) and provide perpetual system updates. I know I'm breaching my NDA with Apple and they'll probably sue me, but I can sleep soundly at night safe in the knowledge that my TiBook 550 will last as long as the titanium itself which coats my blessed companion. ;-) --Fred |
