My knowledge of technical aspects of computers is very limited, therefore I apologize if my question sounds stupid:
I've heard this claim that Centrino processors are considerably less power-demanding than other types/brands of notebook processors. Can anyone tell me if this indeed true???

Thanks.

They have a feature that allows them to adapt their speed (and thereby power consumption) dynamically - giving you more autonomy ... but running them at full speed - will also consume quite a bit of electricity. Typically however (for office work, etc.) the processor can run a lot lower than it's designed to without you ever noticing.

Anyway ... Just in the market for a notebook and a word of warning to everyone who's doing the same .... there's now the i915M chipset available for Centrinos (Sonoma) - but beware ... although the chipset support DDR2 and SATA ... many vendors have opted to stick with DDR memory and regular (parallel) ATA disks .... thereby pretty much nullifying most of the gains of the platform

If you really want to learn about such things I suggest tomshardware.com This is an excellent resource, I have been out of the computer building loop for several years, but I was able to make a couple of decent systems a couple of years ago with help from THG. They are mature and pretty cheap, but they are running like champs and keeping the wife and son hapy as I type.

Note: while THG does link to things like pricegrabber, etc. they don't actually sell equipment themselves, just review it, and help people understand how stuff works.

Uh, Intel Centrino isnt a Processor, its a "mobile technology", the processor is just your run-of-the-mill Pentium M. The new technology's biggest weakness may be its confusing naming scheme. The Centrino technology, formerly code-named Banias, includes a CPU, chip set, and wireless hardware. The chip is called the Pentium M, (not to be confused with its Pentium III-M and Pentium 4-M predecessors), the chip set is the 855, and the wireless hardware is named the Intel Pro/Wireless 2100 Network Connection. To call a notebook a Centrino, and to reap the benefits of Intel's marketing muscle behind that name, vendors must use all three parts. Notebooks using only the processor and chip set will carry the Pentium M label. How does Centrino help battery life? For starters, the 1.3-GHz, 1.4GHz, 1.5-GHz, and 1.6-GHz Pentium M chips draw an average of less than 1 watt of power. (Intel also offers 1.1-GHz and 900-MHz versions, which average one-half watt, for subnotebooks and tablet PCs.) The older Pentium 4-M processors gobble an average of 2 watts. Most mobile users don't want to sacrifice performance to get long battery life. That won't be an issue for Pentium M-based notebooks, thanks to a more efficient processor architecture built from the ground up to be a mobile part (Intel's previous mobile chips are reconfigured desktop parts).The new chip completes more instructions per clock cycle than today's P4 chips (which favor higher MHz instead), and the Pentium M has a 1MB Level 2 cache (twice that of the P4's 512KB L2 cache). As a result, the three 1.6-GHz test notebooks landed impressive PC WorldBench 4 scores, outpacing notebooks with faster-running P4 and P4-M processors. (got most of this info from PCWorld).
