    Contrary to this was the exciting thing Toshiba did with the Libretto 50CT when they ran out of Pentium 75 chips... they started putting in P120s downclocked to 75. Unfortunately I didn't get one of those, but I *was* able to OC my 75 to 100... too bad someone stepped on my libretto and cracked the screen, eh?

      What if the Car had a sticker on it that said V8.

      Most end users aren't going to do research on the internet before they purchase a computer, they are going to go into the local computer store and buy one. If that laptop that they buy says it runs at one speed, but then doesn't, they're getting screwed, and it's not their fault because they didn't do research, it's false advertising.

          So by your logic you wouldn't mind if I sold you aa computer that was advertised at 2.2 gHz but that was permanently and unalterably (at least w/o doing warranty-voiding and probably difficult alterations) underclocked to 2 mHz? After all, I didn't lie to you; it has a 2.2 gHz processor in it. I mean, I kind of doubt you ask "yes, it has a 2.2 gHz processor, but does it RUN at 2.2 gHz?" when you're ordering.

      If you bought an old Mustang and found out it was a four cylinder POS and not an eight cylinder monster would you feel cheated?

      I would feel cheated if the dealer told me it was an eight cylinder mark2, and expected me to do extra research to find out that the mark2 eight cylinder engine would disable half the cylinders whenever I took it out of the driveway.

      The problem has two possible solutions (and I'd recommend a combination of both):
      1. Consumers should better educate themselves before buying, or
      2. Companies should avoid using misleading advertisements.

      Most folks see a laptop ad that says "2.0 Ghz processor featuring SpeedStep technology," but only come away believing that "this new 2.0 Ghz computer is .8 Ghz faster than my current 1.2 Ghz computer."

      We've seen similar naming problems with 3d graphics cards. Geforce4 MX (slower than Geforce 3ti) vs. Geforce 4 4600 (faster than 3ti), or Radeon 9700 vs. Radeon 9700 Pro. Sometimes "Pro" or "Deluxe" means better. Other times "Pro" or "Deluxe" means crappier. (Ok so deluxe usually means crappier, but you get my point)

      I think the main problem stems from the fact that computer performance cannot be fairly conveyed in a few convenient, marketable numbers. AMD has been combating that status quo with their XP naming scheme; Athlon Tbird 1.4 Ghz vs. new Athlon XP 1600 (runs at 1.4 Ghz) vs. Pentium 1.6 Ghz.

      So, who is responsible for getting the information to the customer that speedstep technology would significantly slow down their portable computer whenever they go on battteries?

        Speedstep is a fairly easy thing to research; they make a point of saying that laptops have it.. it's quite clearly labeled as such....
        And a speedstep enabled machine will let you run it at full clock all the time if you want to, easily. For instance, my laptop has a nice button on the windows system tray that lets me flip it between different cpu settings.

        In this case, the laptop does NOT have speedstep, it's a desktop processor, and the laptop is basically hardwired to run it at half speed when the AC is disconnected, the user has absolutely no way to change this behavior.

        It's not a common behavior, and one I think most readers here would not even know about until they looked in detail at those specific models of laptop.

        No, Mhz is not an all-encompasing speed indicator. but it's still quite releveant, and the difference between 1Ghz and 500Mhz is rather large, especially when you are forking out several thousand dollars.

      this has happened all the time in pc industry too for at least 8 years, oem puters like dell/ibm & likes are often dubbed to be fast and whatnot, while in reality they're not, like ibm aptivas that had l2 cache as option.

      Actually, I read a while back that auto manufacturers are developing a "speed-step" like engine management system for cars, if it isn't out already (can't find articles now...). Basically, when you are cruising along at moderate speeds, and don't need all your rated power from your engine, it doesn't send fuel or spark to certain cylinders to save gas. If you step on the throttle, it activates them again. I think it was Mercedes-Benz who was playing with this. I might be wrong, but I think the corvette might have something similar? Anyway, it does exist, at least on paper for now.

      You must not have read the specs very closely, or compared it with other models, or read many reviews.

      I dunno, it seems that the parent poster didn't read the article. From THG:

      Even more annoying is the fact that Dell documents this energy-saving feature neither on its German- language homepage nor anywhere in the handbook. The English homepage, in the meantime, features a footnote: "Power management features limit processor speed when running on battery." This is pretty well hidden, however.

      So right off the top, if you're German, then Dell isn't even going to tell you that they're selling you a desktop processor that's automatically crippled when running on battery. If you're English-speaking, then you still have to have very good eyes. The "power management features" quote is buried in a fine-print footnote at the bottom of the technical specs page. Further, nowhere on the pages for the Speedstep 250N is the actual slower clock speed noted. At what point is the footnote no longer sufficient? On battery power, the processor drops to 0.7 volts and 300 MHz. Can I complain yet? I'm getting great battery life, after all...

      The parent poster is correct--when making a major purchase, it is a good idea to read product reviews. What we have here, however, is a case of deliberately deceptive (and possibly fraudulent) marketing. It's like advertising an automobile as a V8--but four of the cylinders stop firing whenever you're not in your driveway. If Dell is going to advertise a 2.2 GHz notebook, then it should be able to function as a 2.2 GHz notebook even when it's not on my desk at home. Dell should reasonably be expected to realize that their notebook computers are going to frequently be used on battery power--the clock speeds cited should be 2.4/1.2 GHz at the top of the page, not 2.2 GHz with a tiny footnote. Anything less--even if barely legal--is still slimy.

      As an aside, many Toshiba and Compaq laptops allow you to change a control panel setting to say, "Damn the batteries, full speed ahead!" or words to that effect. Consumers familiar with this friendlier incarnation of SpeedStep may be in for a rude surprise.

    Did you bother to figure out what SmartStep/SpeedStep means?

    If you did a modicum of research you would know that you run at a far slower speed in battery mode.

    Now Toshiba DOES allow you to fix this setting (in the control panels) but this should not come as a surprise to any educated consumer.

    When I was shopping around for a laptop for my wife we came across a darling little Toshiba Portege- and one of the first things mentioned in the CNET review even mentioned "Mobile Pentium III with Intel SpeedStep technology" and went on to explain what SpeedStep meant.

    So when my wife types away in class if she can't find an outlet she can expect it to be slow. Easy Solution.

        When I bought my laptop (a Toshiba Satellite [snerk.org], which I'm exceptionally pleased with, FWIW) I asked questions, compared it with the laptops in the store, and understood what the differences were. I also got assurance from the sales person that I could return it within 30 days for a FULL MONEY BACK REFUND if I was not satisfied with the purchase. For the next 29 days, I proceeded to, figuritively speaking, beat the snot out of it. I used it on battery, experimented with power saving features, read the manual cover to cover, exploited all the features of it, installed Linux (to the point where every piece of hardware was fully functional). In short, I made sure that my laptop suited all of my needs, and if not, that I had recourse so that I could exchange it for one that did.

        It's a year and a half later (halfway through my warranty - eep!) and I'm still just as happy with it as the day I got it.

        Point being; I did my research beforehand (it was actually about 2 months before I bought it. As a result of my patience, I got an extra 200MHz, 5GB of HDD space, and double the RAM), then I made sure I was satisfied with my purchase before it was too late.

        For all who've said 'Caveat Emptor' - good on you. Merely having a credit card isn't a license to spend money like it's going out of style. Spend wisely, think before you buy, and most important of all pay attention.

    The article says they clearly state this is the case, maybe they changed something, or you didn't look very hard.

    Either way I'd return it, and ask for one that runs full speed.

    I think this is generally a good idea, the way I use a laptop it would work well. When I am at a proper desk, I do the serious "work" that takes more CPU power, and I'm generally plugged in. When I'm using batteries, it would typically be less demanding applications (reading email, simple quick work in ofice software) and I don't need all that speed. Realistically most computers are overpowered for the work they need to do. Here at work I have a 350MHz Pentium machine, and it works fine.

      How does this apply to Apple and its PowerBooks/iBooks, which get far greater battery life than PC laptops? Sorry, but that's quite a broad generalization you've got there.
      • The RISC based PowerPC designs run a lot cooler and more energy efficient than any recent Intel/AMD chips. That's why there's no 'mobile' versions of those processors.

        Of course, some smartass is going to say that Macs are running at half speed already. All I can say about that is that my 3 year old iMac runs everything I need pretty good, save for 3D games.

      • I have daily experience with hundreds of apple and PC laptops (about 50/50) and honestly the apple's batteries dont last much longer then a quality pc laptop. Apple designs with battery power in mind from the start, many consumer and high performance pc laptops couldn't care less. Some of these will have battery life's 30 minutes. When compared with similiar laptops the Apple battery life isn't anytihng to write home about. I still think the case designs on the Apple laptops are worlds ahead of their pc counterpart.

          Well, considering that my Apple Titanium PowerBook gets 4 to 5 hours of use consistently out of a full battery, I would say that's something to write home about. There is quite a difference between having 4 hours of use and having 30 minutes of use.

          The great thing is that even with high-drain activities, such as viewing a DVD, you regularly get 2.5 hours of battery time. I'd love to see a similar high-end non-Apple laptop do that. There might be one or two other laptops out there that can do that with only a single stock battery, but I'm sure that they are rare.

    has the same feature (Compaq Armada E500), although you need to enable it by installing a SpeedStep (I believe is the name) 'applet' from Intel (it's a PIII chip).
    I don't see why you would need it to run at the full speed on battery anyway. If you're doing something CPU-intensive enough to need the full speed of the chip, then you can almost certainly plug it in; for most other things, half speed is more than enough and doesn't even get noticed. It's not like you're only running with half the RAM active or something like that.

    In fact, you mentioned that you saw it on THG. Did you notice it at all yourself when using the laptop? Or did it run just as well, and you just like getting offended at these sort of things (which seems like exactly what you're doing here).

      No it doesn't... did you even read the article? Mobile chips have the Speedstep function, that function is not on desktop chips, so to save some money Dell is using a some hack to the bios to effectively throttle the desktop CPU.

      I also bet your laptop doesn't lose half of it's speed, my 700 MHz PIII goes down to 550 when on battery mode, not 350.

      • At some point writing I must have forgotten that it was a desktop CPU in the article. Point conceded :)
        You're also right about the half thing, my 800MHz goes down to 550 or 600, I believe.

  • While I don't think any manufacturer specifies the speed of the machine to get the maximum amount of battery life, this article does not tell us what the speed of the mobile P4 is while it is in energy saving mode...

    There are many reasons why Dell wants to put a desktop CPU in the machine, why don't they give the user the option of running it at full speed while on battery sacrificing battery life. I know my Apple PowerBook gives me several options on energy consumption while on battery, including running full out.

    Anyway, no manufacturer states the speed of their machine while on battery. They usually state the battery life depends on configuration and use. Dell is no different. If you go to the specifications page on the 250N [dell.com] you will see that it states that Power management features limit processor speed when running on battery. It's not like they are hiding this information from the purchaser, learn to read the fine print. I don't think that this is enough to get that excited about...

    Intel doesn't even advertise the lower core clock speed anymore for the P4, but on the P3-M 1 GHZ, the technology dropped the chip to 733 MHz when on battery power.

How hard is it to understand: 1) Computers have so much speed now that only the most graphic intensive game or the most complex calculations are going to come close to pushing their limit. 2) Batteries have not kept up with chips, and thus have laughable capacities for the things you use. 3) Unless you carry spare fully charged batteries with you, you have to be a moron not to use the incredibally helpfull feature that you are complaining about. Even if you are playing Doom, it is far better to play Doom for 2 hours with a slight jerkiness and speed reduction, than to lose power and have to kill the game 1 hour into your 2 hour train ride.

    There's not a whole lotta difference between "mobile" and desktop processors other than packaging.

    Desktop CPU's use PGA's that were designed for socketed use. The extra 4 millimeters from the pins sticking out is worth it because it means the CPU can be swapped in and out. Flexibility is the goal here.

    Mobile processors usually come in a BGA package because they're soldered directly to the motherboard via wave solder, or UV cured solder. Since they don't have that extra 4 millimeters of pins sticking out the bottom, their profile is smaller than that of a desktop processor.

    Right now though, it seems a lot of manufacturers are at least trying to make the newer laptops as flexible as a desktop by offering expansion busses to replace the laptops video card, processor, ram ect.

    Remember 7 or 8 years ago when you wanted to get laptop memory? Everytime you wanted to upgrade you would have to order a custom stick because the manufacturers were all doing their own thing. Back then they thought they had to keep every vertical market on their laptop to themselves.

      Um actually the CPU's are very different. Mobile P4's for instance use a lower core voltage. Other generations of mobile Intel cpu's have been based on smaller processes then their desktop brethren, or they have had fewer functional units. Another difference is speedstep, the mobile cpu's have the speedstep circuitry built in, the desktop cpu's do not, hence this article. For everyone that can't read what happens when you use a speedstep chipset with a non speedstep cpu is that the cpu gets stuck in the lower speed processing mode and cannot return to normal processing state without a reboot whereas the mobile cpu's will return to full speed with a simple software controll.
    • Maybe in the past, mobile CPUs were soldered-on BGAs, but in most recent laptops (Dell Inspiron 8x00, probably most other recent Dells), even the "Mobile" CPU is replacable. In the I8x00 series, you can even upgrade the video card (this made Slashdot a while ago).

      Mobile cpus have a pretty good bit of modificaton over desktops cpus, primarily designed to reduce heat. cuz the cooler it runs, the faster it can run safely in a laptop enclosure.

    Laptops are "portable" computers, but not really "mobile". The distinction, as I see it, lies in the fact that even with a fully charged batteries, many laptops don't give very useful operating times unless you're plugged in to an AC outlet.

    Assuming you can find an outlet wherever you're likely to want to use your PC, laptops can be a decent choice. But without access to an AC outlet, you're not going to find a laptop to be useful for more than 30-40 minutes or so.

    I can't tell you how many times I've had my laptop just shut down with no warning because the AC cable was loose and I didn't notice, and I'd only been using the computer for maybe 20-30 minutes.

    So that's why I say a laptop is portable, but not mobile. You can't really go that far with one while it's umbilical is plugged in, so it's not really fair to call a laptop mobile.

    And, if you're going to be plugged in 90% + of the time you're using it, then you're not going to have to deal with the reduced performance issue anyway.
    • Get a laptop with a Transmeta chip. I have a Fujitsu P-2046 with an 800 mhz Crusoe, and it goes all day (they rate it at 14 hours, I get around 10 with full brightness, and close to 15 when it's closed and just playing MP3's). They use a similar technology to Intel's speedstep, except that it will scale all the way up to 100% of rated speed if needed (I don't think Intel's will do this). Also, you can select how high you want it to scale (in Linux, there's a simple utility to do this).
      • Intel CPUs can scale up to 100% speed.

        Unfortunately, they can only scale down to a preset speed (In fact, they can only go to that speed or max, nothing in between). IMO that speed is still too high - 1.2 GHz on my P4-M 1.7.

        The Transmeta advantage is that it can adjust its clock speed far LOWER and in finer increments.
    • 30 to 40 minutes? you need a new laptop, my friend.

      My TiBook can watch just under 2 DVDs, full-screen, before the battery goes out. That's probably around 3 1/2 hours or so. Enjoy your "portable" computer, I'll enjoy my "mobile" laptop.

    • Obviously, you don't own a Fujisu P-2000 [fujitsupc.com]. With 2 batteries attached, I get 14 hours of battery life with a notebook that weighs under 4 pounds. Granted, its no speed demon, but it certainly fits anyone's definition of a mobile pc.
    • I haven't used a PC laptop since about 1994 - that was a 33 MHz Pentium with 16 MB of RAM and a monochrome screen which would run for a little over an hour on its battery, and that was with every screen-dimming, hard-disk unspinning, power-saving option I could find turned on.

      Every Mac laptop I've used since then would run for at least two hours on one battery. My current 500 MHz iBook runs for just under three hours on a charge, will sleep for over a week unplugged, has a wake-from-sleep time of two seconds, and can be safely run completely to battery exhaustion - with its last gasp it dumps the whole processor state to disk, so if you then plug it in and hit the boot button, you come up exactly where you left off.

      I knew things were bad in the PC universe regarding power consumption, sleep and wake, and state preservation, but is it really that bad? Has battery life really not improved for PC laptops since 1993?
    • My Toshiba Protege 2000 with both batteries lasts for about five hours. I used to sit outside the Uni with wireless during weekends (no coverage in the building we had access to during weekends, doh!). 5 hours with Wireless enabled (and usually hdd spinning because I'm downloading something), that's good enough for me.

      I'll get more than that when I'm only playing games, and you won't believe how many hours it'll play mp3s if I put on a playlist and let the screen black out (that's the real power drain in this one).

      Oh and speedstep is a great technology. Dynamic switching makes it transparent for most tasks, if not I can configure it as I want it. Nothing like P3-175MHz @ 0.6W or thereabout (750MHz @ 10W on full power) for when you're just idling.

    I shelled out big bucks for my "desktop replacement" Toshiba satellite 5000 which has a desktop PIII 1000GHz chip. Unfortunately, the processor runs so hot that it constantly overheated and powered down. The BIOS "fix" clocks down the CPU when it gets hot (which is always) so it doesn't shut down spontaneously any more, but now I have a VERY expensive pentium two equivalent. When you apply the BIOS fix it changes the BIOS so that the install disks which contain the gimped version of your Win OS won't unstall on the "unrecognized laptop" until you take it in to an authorized dealer.

    Not to mention that this laptop doesn't even have a standard bios that you can configure. It's some wierd proprietary thing that lets you make a password and select boot priority and that's it.

    The sound is problematic too because it runs through ACPI, which is fine for windows, but very difficult if you want to run linux. So for the one in four linux distros that can actually boot up on this laptop, so far none of them have sound that works.

In the full power mode you run your processor at full power. One of the default modes is power conserve mode where you processor runs at lower and lower speeds as the power drains. However you can run the full power mode when running on just batteries, you just don't get as much battery life. I still find I get close to the advertised 3 hours. My two biggest complaints about the Toshiba is that the bottom tends to get hot, and there is no docking station port. All in all, really happy.

If you were on the road and needed all the CPU horsepower, you got it, but inbetween clicks and hard drive activity, the CPU throttled down.

    As to the chips themselves, lower power RISC chips actually can be used in both desktops and laptops and you don't have to deal with this sort of engineering workaround of marketing. The other issue with using many desktop chips in laptops is heat. For instance, my mother purchased an Wintel laptop with a desktop chip that was designed with a huge fan on the bottom of the computer, so that if you actually placed it on your lap, you would block the fan and the laptop would overheat and shutdown. I bought her a Powerbook (the first Mac she ever owned) and she has never gone back to the Wintel crowd. It's thin, it's light and she always has all the power she needs battery or AC power.

    This post is not legal advice and does not create an attorney-client relationship. If you need legal advice, you should consult with a competent attorney who is licensed to practice in your state (or other jurisdiction outside the U.S.).

    That being said, every state in the US has a version of the Uniform Commercial Code. Section 2-313 deals with Express Warranties. Any affirmation of fact or promise or description of the goods creates an express warranty which is breached if the goods sold and delivered do not conform to the factual affirmation or description or if the promise made is broken. For example, if the processor speed is labeled as 1 GHz, the consumer is entitled to rely on the 1 GHz measure. A split 1 GHz/500 MHz ration when running on AC/battery does not conform to the affirmation of fact (processor speed) made by the merchant and could be said to breach the express warranty.

    Section 2-314 is the Implied Warranty of Merchantability. The warranty is created simply by virtue of making the sale. If the goods sold are not such that would pass without objection in the trade then the warranty has been breached. Here, the argument would be that the industry creates mobile versions of chips for laptops because of battery life concerns. If someone wants to depart from that practice and use a speed slowdown to reduce power consumption, then that fact must be disclosed and agreed-to by the consumer prior to the sale. Otherwise, the consumer is entitled to rely on the standard practice when making the purchase. Such undisclosed use of "slowed" desktop processors would not pass without objection in the trade and could be said to breach the implied warranty of merchatability.

    Additionally, virtually every state has a "Little FTC Act" or Consumer Protection statute. These statutes outlaw "unfair or deceptive" business practices. Breaches of warranty are usually automatic violations of these statutes. The penalty is usually up to three times your damages (for example, the cost of your laptop times 3) plus attorneys fees if you hire a lawyer.

Furthermore, for most applications, you're just not going to need something that fast when you're in a position where you can't get to an outlet.

Instead, they would read a track, fill up, and then skip a track or more; the disk would have a 1:2, 1:3, ... interleaving of tracks. If the drive and controller were in tune, the data could be read one track after another with no gaps; 1:1 interleave.
