Has anyone returned their MBP because of this? Any success on getting the restocking fee refunded?

I doubt I would do this.. but I'm just curious.
 
You don't know, you are guessing.
"Guessing" based on sound engineering principles and a realistic look at the bandwidth capabilities of the system as a whole is better than simply bemoaning a change without an accurate understanding of what it might impact (or not, as the case may be).
 
One could only hope. I'm contemplating returning my MBP 13". This is insane.

The horror...the horror :eek:

I read a comment on this issue on a blog that said it best:

"Apple hurts us because it loves us" Not like this "issue" if you even want to call it that is going to make me enjoy my computer any less...for the 1000's of people whining about this, how many does it actually affect? And lets not get into an argument about "future bottlenecks" because everything is a potential bottleneck to something bigger and better coming out in the future.

I would welcome a firmware update for a slight peace of mind but I am not going to go crying bloody murder and demand refund at the top of my lungs over it..to each his own I guess. By the time it actually becomes a "real issue" I imagine most of us (me included) will have brand new notebooks...is it bad that I don't consider $1400 THAT much money for a notebook? Maybe I am priveledged that I earn a decent living, I don't know.
 
The proof is simple engineering. If you have two otherwise identical integrated circuits, with one running at half the clock speed of the other, the slower chip will consume less power, every time. This is a fundamental of electrical engineering. It's the same reason your mobile CPU will clock itself down whenever possible. It saves power - and the same principles apply to a serial communications interface such as SATA.

A couple thoughts come to mind:

1) The 17" is of course physically larger and can hold a physically larger battery, making the concession less of a priority

2) The 17" retains a 2.5gbps expresscard/34 slot, which could theoretically be used to provide a means of external expansion that could take advantage of a fast SSD on a 3.0 gigabit SATA bus

LOL.. what a BS post. You cannot seriously compare the effect of downclocking a cpu vs downclocking SATA speeds on battery life. There's no analogy there. There is no evidence that SATAII would use any more power than SATAI- and if it does, it would be absolutely negligible. And by negligible, I mean it would use such a ridiculously small increase in power that it simply would not matter.
 
How do you know that it has an affect on battery life? Where is your proof? As far as I've read, no one has been able to confirm this.

And there is an easy rebuttal for that argument. If it was to save battery, then why does the 17" model still have the 3.0 SATA?

Better yet, why does MacBook Air still use SATA 3? You can't even upgrade it to a better SSD yet (compatibility issues) and with its small battery and low power usage it would take better advantage of it than MBPs. This "longer battery life" theory doesn't seem plausible.

I second you.

I also do not understand the logic on why people want to return their MBPs now and not wait until they get an official word from Apple, and a possible fix...:confused:

I still think this is going to be fixed in some way and hoping for the easy firmware update. I'm a proud owner of a new MBP 13" and couldn't be happier with it's screen.

I'm already stoked about the NVIDIA announcement of better GPUs and I am taking it easy on this one. I will ride the wave and try to enjoy my new lappy the best I can.

I am not in any way defending Apple and I do think this is a slimy, clever move from them. But until we get their response, I am holding off my complaint.

Says who? What's your engineering background? The fundamentals are exactly the same.

How do you figure? We've already established that the hardware used is identical. It doesn't take a genius to figure out that running a serial communications controller at a slower clock rate will result in power savings. A clock rate cut in half, particularly when talking about chips that operate in the multiple-gigahertz range, can be quite significant in terms of power savings.
- and if it does, it would be absolutely negligible. And by negligible, I mean it would use such a ridiculously small increase in power that it simply would not matter.
By all means, prove it. I'm listening.

Exactly. Someone please explain why the Air has 3.0 and the Macbook Pros don't......"logically", as from what I keep reading in this thread.

But that doesn't mean that having a 3.0 cap will use any more energy than a 1.5 cap. Shouldn't this be all dependent on the usage? If you are using an HD that is going well below 1.5, there should not be any more power usage than needed.

Serial buses like these operate at a fixed frequency (1.5gbps or 3.0gbps respectively). The clock rate does not change based on actual data throughput. Unlike CPUs with speed-stepping technology, there is no provision in the SATA Standard to downclock the bus during periods of inactivity.
 
"Guessing" based on sound engineering principles and a realistic look at the bandwidth capabilities of the system as a whole is better than simply bemoaning a change without an accurate understanding of what it might impact (or not, as the case may be).

Since I have a B.S.E.E. (do you?) I think I can understand the issues. As far as bemoaning the change, I can see the change in usage of my X25M. If I had known about this change before trading in a newly purchased 2.66GHz (non SD slot) I might not have made the exchange.
 
Personally - I think the AnandTech article helped me understand this issue and it's impact on my situation the most. I put my X25 160GB into my new MBP (first mac by the way) so that it would be fast and launch the OS's - OS X and Win. 7 fast - at 160GB I am not going to be moving huge stuff around.

Do I like where I am with this NO. Do I buy into all this class action stuff - I find it funny, Apple never claimed the MBP has 3.0Sata regardless of what past machines had.

I think I am going to keep my MBP - heck it was only about $1100 after discount.

I would like to think they will come clean about this so that those that want to return can return the MBP's.

Just my 2 cents.

Sweet! So then you're obviously aware that the basic ways to reduce power consumption of an IC are to 1) miniaturize components (ie switch to a smaller fab/process technology), 2) layout optimization and/or decreasing resistance through improved semiconductors, or 3) Reduce the clock speed.

Since "1" and "2" are obviously off the table here...

As far as bemoaning the change, I can see the change in usage of my X25M. If I had known about this change before trading in a newly purchased 2.66GHz (non SD slot) I might not have made the exchange.
Noted on artificial benchmark != "see change"

Of course reducing clock speed reduces power. But how much power is this consuming on a total percentage. Without more data it's difficult to say, but it "seems" like the percentage might be small. Heck, the seven hours battery life claimed is clearly a contrived number, if having 3.0Gb SATA had a 1% impact, then the change is stupid. If it was a 10% impact then it's understandable.

As far as artificial benchmarks, no I can see it in real life. Does it affect my boot speed, no. Does it affect small random actions, no. But if can be seen in file copies and other things. I am also seeing some odd random pauses. I'm not going to blame that on the bus speed change, but I've never seen these sort of pauses before and they didn't start until I put the X25M in the MBP (it has worked fine in a previous UMP).
 
I second you.

I have the uMB Special Edition 2.4/4GB/320HDD and I know one issue I had when buying this unit from BestBuy was a 14 Day no restock policy. I think the logic some people are using is that it is better to return within 14 days and rebuy later while waiting for an answer from Apple, then to sit by and wait for the same answer only to find that 1.5gbs is jus the way it is, then they have no recourse of action.

I originally purchased the 15.4 uMBP 2.53 but since I only had 14 days to return or swap for a full refund with NO restocking fee, I waiting until the 12th day, then decided to return the uMBP only to get the uBM 2.4/2GB/250HDD which was the diff from $2499 to $1599 which was only $900 but if I had waited then I would have been charge 15% of the $2499 just to downgrade.

I think people returning them until Apple makes it official is a reasonable thought process, otherwise people will be left holding the bag if Apple says there is nothing that can be done with the new uMBP 13" 1.5Sata I issues.
 
i dont have a BSEE or whatever it is....


but you fix 10 problems at 1% each...thats 10%

1x10=10



can i have a cookie now ?
 
Excerpt from this article which people should understand:

"All three of the SSDs in the table above would be interface limited on the new MBP because of their high sequential read speeds. If you were copying large files from the SSD in your MacBook to a similarly fast device, the transfers could take longer. I doubt the performance difference would be significant or noticeable in real world notebook usage, but it doesn’t change that there’s no reason to take a step backwards like that. In the coming years we’ll see more drives that can consistently break 150MB/s; Apple artificially limiting performance today would just hinder progress. "

Would this be even more of a problem for those that tweak their laptop further by replacing the optical drive with an SSD for a 2 SSD drive RAID0?
 
LOL e-cocks are wanging it out.
:D

I can here the Apple statement now that would bring this thread to its knees:

Oops, we screwed up. "Al" the main motherboard guy here at the assembly plant was on vacation. "Fred" (his backup) forgot to enable the the 3.0 switch.

Sorry,

Here's the fix.
