Core 2 Boosts MacBook by 7%, Undervolting Ups Battery Life and Drops Heat, Firmware Update for MB and MBP, and More
This Week's Mac Notebook News
This Week's MacBook, PowerBook, and iBook News
Benchmark results are in, and the new Core 2 MacBooks come out about 7% faster overall than the "Core1" models they replace. Not a bad improvement for no increase in price, and MPEG2 encoding improves by 20-25%.
One way to increase your 'Book's battery life has been underclocking. For instance, my old PowerBook G4/400 could be notched back to 300 MHz for longer use in the field. But now we're seeing another approach: undervolting, which lets you increase battery life with no performance penalty. And it runs cooler.
The new CoolBook software brings that to MacBooks, and field reports on the Windows side of things are reporting roughly 20% greater battery life by undervolting. This could be a great way to keep those Core Duo MacBooks from overheating, as the CoolBook site shows a drop of 13-15°C (18-27°F) when undervolting.
Apple has released Firmware Updates for all Intel Macs, inlcuding the MacBook and MacBook Pro models.
All prices are in US dollars unless otherwise noted.

News & Opinion
Macworld's James Galbraith reports:
"Switching from a Core Duo processor to the next-generation Core 2 Duo will yield a performance boost. Our benchmarks for the recent iMac and MacBook Pro updates revealed as much. Like those two product lines, the wildly popular MacBook laptop also got a processor upgrade to the Core 2 Duo; however, clock speeds remain unchanged from the previous installment of consumer portables. As a result, the gains from this update were much more modest than what we've seen from previous Core 2 Duo-powered systems."
The Apple Core's Jason D. O'Grady says:
"Everyone's heard of overclocking a CPU to wring the last few drops of performance out it, right? Well, a notebook jockey's equivalent is called 'undervolting' and it's designed to increase battery life not clock speed.
"An article in NordicHardware explains the concept:
"The technology used is called undervolting and even if reducing the voltage would be a more precise description the name is still pretty easy to get. By lowering the voltage to the processor you can not only drastically lower the heat dissipation, but also increase the battery time significantly. There are, believe it or not, no downsides with this method, if you do it right...."
The Apple Core's Jason D. O'Grady reports:
"Hot on the heels of my story yesterday about undervolting your Core Duo CPU to save on battery and heat comes a nifty piece of shareware. CoolBook is a GUI to control CPU clock speed and voltage. It's like the author was reading my mind!
"CoolBook is a $10 shareware application for the MacBook and MBP that allows you to adjust the frequency (clock speed) and voltage of Intel Core Duo and Core 2 Duo CPUs.
"According to the author's published benchmarks his MacBook (1.83 GHz) temperature decreased by as much as 14°C (25.2°F) just by dropping the voltage from 1.2125 V (Apple default) to 0.95 V (the minimum)....
"In my experience Core 2 Duo MacBook Pros can run as much as 40°F cooler than Core Duo machines. I don't consider these voltage/frequency/fan tweaking applications necessary on newer C2D machines, but they're practically required for Core Duos. Especially if you want to use your machine on your lap."
Ars Technica reports:
"When the 15-inch MacBook Pros got bumped to Core 2 Duo, their 17-inch counterparts joined them in the processor bump. However, while the 15-inchers were supposedly available immediately (although some of our staff members would beg to differ), the 17-inch MBP was supposed to ship within the next week or so. That was a few weeks ago, and the buyers of 17-inchers are still waiting."
Consumer Reports says:
"This holiday season, shoppers are expected to spend a whopping $1.6 billion on extended warranties for laptops, flat-screen TVs, other electronics, and appliances.
"And almost all of it will be money down the drain....
"For the consumer, extended warranties are notoriously bad deals because:
- Products seldom break within the extended-warranty window (typically around three years), our data show.
- When electronics and appliances do break, the repair often costs about the same as the cost of the warranty.
"We have long advised against extended warranties. In fact, we feel so strongly that consumers are being misled about them that we took out a full-page ad in USA Today on Nov. 14 (see below) to warn shoppers."
Editor's note: I'm a longtime extended warranty skeptic. Whether they make sense depends on your risk tolerance and to a large degree a roll of the dice. In a dozen years of Mac ownership, I've never purchased AppleCare coverage and have never missed it, which means that I've saved more than the cost of a new MacBook Pro over the years. cm
Editor's note: I'm a longtime extended warranty skeptic as well, but I bought AppleCare for my PowerBook G4/400. Good thing, too, as I had it in 2-3 times for service, including replacing the screen due to a partially failed backlight in the third year. AppleCare costs a lot less than a screen repair on any 'Book, and I think it's an especially good idea when buying a newly designed model. dk

PR: Samsung Electronics Ltd., the worldwide digital consumer electronics and information technology forerunner, ratchets up the strength of its 2.5" hard disk drive offerings for notebook and enterprise computing applications with the introduction of the powerful new M80 SATA Series and M80 Series. Both series utilize advanced Perpendicular Magnetic Recording (PMR) technology, feature an optional industry leading free-fall sensors and offer increased storage capacity, now up to 160 GB.
The M80 SATA Series features the 80 GB HM080HI, the 120 GB HM120II and 160 GB HM160JI. The M80 Series includes the 80 GB HM080HC, the 120 GB HM120IC and the 160 GB HM160JC(1).
The M80 SATA Series and M80 Series are Samsung's first hard drives based on PMR technology. Unlike traditional longitudinal recording technology, which lays data bits end to end where they can flip and corrupt data on the disc, PMR technology places the data bits perpendicular to the disc, which reduces the corruption factor. In addition, by placing the data bits standing on end, more data can fit onto a disc, allowing for greater storage capacity. With PMG technology, users can fit up to 40,000 MP3 songs and 160 hours of video on a 160 GB Drive.
Samsung's newest 2.5" drives offer users increased damage risk protection by incorporating industry-leading free-fall sensors. Many notebook hard drives on the market today have an operating shock tolerance - the amount of shock the drive can take before damage - up to 325G. Samsung's new drives with the free-fall sensor provide an industry-leading 700G of operating shock tolerance. Hard drives enabled with the free-fall sensor are better able to detect changes in acceleration caused by a freefall. The free-fall sensor parks the drive's head on the ramp and turns the hard drive off, protecting it from damage caused in a fall. This offers a dramatic increase in reliability and resistance to hard drive damage caused in the event of a fall.
Unlike much of its competition, Samsung's free-fall sensors are located on the hard drive, not the notebook's motherboard. The added benefits of this onboard integration include faster response time in the event of all fall, an improvement in the quality of fall detection, and a smaller minimum fall detection rate of just 30cm.
"The rate of today's mobile workforce and notebook PC users is rapidly growing like never before and Samsung is committed to providing the most advanced, technically sophisticated hard drive solutions available today," said Albert Kim, National Sales Manger, Storage Systems for Samsung Semiconductor, Inc. "The M80 SATA Series and M80 Series, armed with PMR technology, free-fall sensor capability and increased storage capacity work behind the senses to ensure users have all of the tools necessary for the most pleasurable computing experience possible."
Targeted for mobile computing needs as well as enterprise applications, the M80 SATA Series and M80 Series feature a 8 MB of onboard data cache and high performance 5,400 rpm spindle speed. The new hard drives provide cutting-edge shock protection capability through an advanced mechanical platform and able-bodied cover design engineered to minimize the intensity of external shock transmitted to the most critical components of the drive.
Samsung's latest 2.5" hard drive offers are equipped with the company's Hybrid Latch System, a revolutionary new latch mechanism that eliminates unpleasant rattling noises and significantly reduces the clicking noise generated when a drive moves its heads on and off the disk according to the operating modes. The drive uses a Fluid Dynamic Bearing motor to achieve an industry-leading operating acoustic noise levels.
The M80 SATA Series and M80 Series feature 80 GB formatted capacity per disk, Fluid Dynamic Bearing Spindle motor technology, ATA SMART feature set, ATA Automatic Acoustic Management, ATA Device Configuration overlay and Multi-Burst On-The-Fly Error Correction. Utilizing Samsung's SilentSeek™ technology, the drives provide are among the quietest in the industry today.

PR: FastMac has announced that it has begun shipping the highest capacity, extended life battery upgrade for Apple's PowerBook G3 Pismo and Lombard computers. The new 84 Whr battery uses Lithium-Ion cells (with integrated charge indicator LEDs) that are manufactured to the highest quality standards and utilizes TruePower technology to provide up to 68% more capacity than the original Apple battery. FastMac's TruePower battery for the PowerBook Pismo and Lombard is available now for a special introductory price of $139.95 & can be combined with a G4 550 MHz Pismo processor upgrade for a special bundle price of $349.95 ($50 savings). Each battery carries a 1 year warranty and a 30 day money back guarantee.
FastMac's TruePower line of battery upgrades replace the computer's original battery with a larger capacity and longer lasting advanced power cell battery that utilizes TruePower technology. This technology incorporates sensors in the integrated circuit inside the battery that detect undesirable levels of swelling or a short circuit that will power off the battery in certain extreme conditions. TruePower batteries do not contain or use any Sony cells that are subject to the recent series of recalls issued by major computer manufacturers.
FastMac's TruePower battery can also be combined with a G4 550 MHz processor upgrade to obtain the ultimate PowerBook Pismo. Combining FastMac's low voltage, low-power, and cooler running G4 Processor design with the highest capacity battery on the market yields even longer battery run times than a stock PowerBook Pismo.
"With the Pismo's 2 battery bays and our G4 upgrade, you can literally go halfway around the world without a recharge," said Michael Lowdermilk, Business Development Manager for FastMac Performance Upgrades, Inc. "There is no doubt that this is the best battery for your PowerBook."
FastMac says its line of TruePower batteries for laptops are engineered using the highest quality, high-capacity Lithium cells, keeping safety in mind at all times. FastMac utilizes custom form factors and materials to achieve a superior fit and finish, matching the original battery whilst increasing capacity. Each battery is individually tested and includes safety features to protect against overcharge, overheating, short circuits and power surges.
All TruePower batteries carry at least a 1 year warranty and in some cases, a 2 year warranty. FastMac's TruePower line includes battery upgrades for all iPods & all Apple portables released after 1997, including the world's longest lasting PowerBook battery with up to 68% more capacity than the original. FastMac is also first to market a replacement battery for Apple's latest MacBook portables.
TruePower is the name of an innovative new technology designed to extend the life of ordinary Lithium Ion cells, commonly used in most rechargeable batteries. More than 4 years in development, this patented technology allows tiny ceramic particles (each less than a millionth of a millimeter in size) to be integrated into the molecular structure of the chemical binding agent found inside each Lithium Ion battery. These particles then link-in with each other & a proprietary energy management circuit to create an extremely dense and highly conductive layer on the surface of a capacitor-enhanced battery pack. This combination delivers the power necessary to satisfy the pulse demands placed on most batteries, whilst ensuring the protection of the Lithium cell matrix. This results in battery packs that can be recharged many more times as well as yielding longer run times per charge. Whereas ordinary battery packs start losing their power within a few months, TruePower-enhanced battery packs continue giving consistent power for long periods, allowing OEMs to offer warranties of 2 years or more. More information about TruePower is available via the website.
FastMac's battery upgrades utilize TruePower technology- a patented material & energy management circuit that is designed to protect the battery's internal lithium crystal matrix from damage caused by power spikes. These spikes occur when the computer demands a sudden high current peak- for example, to turn on the backlight or to load the next data sectors. Over time, these power spikes decrease capacity, runtime and battery life, eventually rendering the power cells unusable. Through the use of TruePower technology, the energy management circuit is able to smooth out the power spikes and lower the rate of decay. This protects the battery and leads to a longer life cycle. Not only does this extend the usability of the computer, it also helps the environment by curbing the depletion of chemicals and plastic materials used in battery products and reducing the number of waste batteries sent to landfills. More information about FastMac's battery upgrades is available via the website.
