More usefully, you're losing ~40% area; ~19% horizontal and ~27% vertical.
It seems that Lenovo currently has a sale on the Y460 (with HD 5650) that takes it under $900. Does anyone have any thoughts?
It's a serious consideration for me all of a sudden; though I'm held back by the thought of an ASUS N82Jv or Acer 3820 (with HD 5650) at $1000 or so - I've heard the battery life is lacking on the Y460.
-
-
all i can say that the y460 gets REALLY hot. you might want to take that into consideration
-
Anyways, the Lenovo being hot was no surprise, previous Ideapads weren't much better. The 14" form factor amplified the problem. Keep in mind though, that Asus is also trying to pack similarly hot parts in the same form factor - expect some warmth. And before anyone brings up the Mx11, do remember that not only does it have a weak CPU, it's also fat.
As for me...After the announcement of the Y460 bbq, I've pulled out of the 14" zone. N61 for me. Optimus be damned. -
I really really really wanted to buy the G73.
But now I have to go to university for a year and a 14" or 13" seems like the only reasonable choice
Ordered the Lenovo Y460. Hope I am not too disappointed. -
While the m11x isn't the best example due to the weak CPU, there's already a number of current examples of similar components in equal or smaller form factors. The Sony VAIO Z is the most prominent of these; the VAIO CW is a great example as well. This Elitebook 8440w has a quad-core i7-920XM and a discrete GPU, no less.
I think the blame lies squarely in Lenovo's hands here; that they've had a history of heat problems in the IdeaPads doesn't speak in their favour. Based on the pictures in the review, it seems like their thermal design isn't very good. In particular, the shared heatpipe seems like a poor design choice. Sure, it probably isn't easy to pack these components into 14", but it definitely seems possible to do it, and do it well. I read somewhere about one of the upcoming laptops having separate side heat vents for the CPU and GPU, but now I can't find the article again.
Besides that, I think the heat issue for the Lenovo Y460 is slightly exaggerated. The test in that review was full load for 12 hours, and that is definitely not typical usage for me.
When using it without the discrete GPU, heat wouldn't be an issue at all. With the GPU, it might be an issue when using it for a long time, but for the most part I doubt I'd use it for that long. To me, the underwhelming battery life seems like the bigger problem. -
If the N81 didn't have any heat issues why would the N82?
-
Sigh... another weekend, another week without a concrete release date...
-
I don't understand either. This thread has over 500 posts and over a month old now, still no release date or price :S.
-
Again, that review ran the Y460's cpu and gpu in a stress-case scenario for 12 consecutive hours. If you plan on doing the same in real world situations, then the Y460 (and the N82) are NOT the laptop for you. Both these laptops pack serious CPU/GPU firepower in a relatively thin chassis.
-
Man, i am getting tired of this waiting....the Lenovo Y460 not being released in Germany....nothing about the N82/PL30VT nor the Acer Timeline series....
Just really fricking annoying! -
LOL, i share the same sentiments with most of you. im tired of waiting, but where im from, there isnt really an alternative for the n82 or 4820t
-
It being on for 12 hours is no indication of good thermals either. At some point during those 12 hours, an equilibrium was reached between the heat generation and heat dissipation. That is, unless you want to claim that even after 12 hours, the heat was still rising? Now then, care to guess when that equilibrium was reached? (Hint: Quite early)
As for other laptops in this range with similar specs...The Vaio CW has a 310M and thus isn't a very good example, and the other two cost a fortune. I agree that it is, and should be possible. But at what cost? -
The temperature difference from the equilibrium would decay exponentially, so yes, the temperature would still be rising after 12 hours - if it wasn't for the CPU automatically regulating its own temperature (I believe it regulates itself to stay below 100 degrees Celsius). The graph showed ~10% throttling, and the tested model has an i5-430M, so that's definitely bad news.
As for when the equilibrium would be reached, I don't know, but I don't see your basis for deciding it would be reached quite early. Nor did I say the Y460 has "good thermals"; they are clearly not good, and that's what I'd expect given the poor heatsink design. However, I figured they might be good enough. Besides, there's plenty of other factors involved, such as the room temperature at the time of testing.
For $900 with an HD 5650, I'd be willing to regulate the CPU's clock speed and voltage down until the heat levels were acceptable.
Also, the VAIO CW has models with a GT 330M, so it's a pretty good example, actually. -
The temperature should be bounded above by the line where the total input of energy into the system is balanced by the rate of energy loss as heat to surroundings, given that the rate of heat dissipation is related to the temperature gradient... so, as the notebook heats up from room temperature (off state), it will asymptotically converge to the aforementioned point of equilibrium. However, given our experience with notebooks, we should know that after 12 hours the temperature should be very close to this equilibrium, and certainly, it cannot exceed this equilibrium.
-
My bad, looks like the CW does have a 330M option, just not on their main site. And it turns out that it is a very good example. http://forum.notebookreview.com/showthread.php?p=5916661&highlight=temp#post5916661. I like that bottlecap idea.
At what point we consider equilibrium is reached is not the point. The point is how fast it gets hot. You've conceded that it's exponential, which means it got hot quite early, and spent the next 10 or so hours just rising slowly. -
They were getting 80 degrees on extended play with the CW; I'd be fine with that.
The mere fact that it's exponential doesn't mean a thing as to whether something happens "slowly" or "quickly" unless you know the exponential constant - population growth is exponential as well, but it happens on a timescale of centuries.
In any case, 100 degrees is the upper limit for the Y460 due to throttling; because of this, the equilibrium could be reached in a finite amount of time, in fact. -
Urgh, I can't say I'd be fine with that, but I think we're missing the point. Heat's never been a problem as long as it stays operational. Problem is whether or not you like it burning your hands, and whether the heat is dispersed away from where your hands are. 80 degree on a large laptop might be okay because you can keep the keyboard area relatively isolated, but on a 14"?
As for not knowing the exponential constant...seriously? Fine, let's not use maths now and use experience. Start putting your CPU on load and see how fast the numbers go up. From my experience, the CPU numbers crank up extremely quickly, and drop even faster once the load's off. The exhaust/keyboard is a different story though, hence my point above. based on subjective experience, it doesn't take more than an hour for those to rise after the CPU's temperatures have risen. Do you have different experiences? -
Well, heat isn't great as it increases the rate at which the components will deteriorate, but even at relatively hot temperatures the CPU isn't going to fail for a long time.
As for whether the heat is dispersed away from where your hands are, the review doesn't really give any detail on that so we can't really decide one way or the other. I don't see anyone with a CW complaining about burnt hands, but I didn't look very hard so if you find a review or forum post with that kind of information please link it. -
I haven't really looked that hard either, VAIOs don't interest me much. http://forum.notebookreview.com/showthread.php?p=5965045#post5965045 has one person complaining about the heat though.
-
I have a feeling the reason the N82 isn't out is because the vendors are trying to clear the X83 and N81 stock. There are sales on these models everywhere...
The N71JV, N61JV, etc are all out already. Just the N82.... -
I think you may be on to something here. There really isn't a good technological reason why the N82 hasn't been released already. Asus loss is HP and Lenovo's gain (Envy 15 2nd gen and Y460 respectively).
-
xoticpc isn't selling the N81 or X83 anymore... Is that a good sign, then?
-
It's certainly not a bad sign!
-
N61/71Jv had the chassis/other parts already designed at the announcement of Optimus: The N61JA and N71JA. The U30Jc had the U30Vt, the the UL50Vf had the UL50Vt.
The N82 did NOT have the N81 - even if the chassis were the same, they needed to add the NEC USB3.0 controller to the motherboard. -
Yes, well... the N82 has been shown in various displays since January, so three months later you'd think it's ready
-
There's a big difference between prototype and mass production.
-
True, but the N82 doesn't incorporate any hardware technological advances that would take 3 months to figure out how to incorporate in a mass production process.
Optimus is software based.
-
Any guesses as to how much the N82 is going to be?
Can i assume it's going to be similar to N81?
cuz the N81 was $ 1,399 in this article.. if it's that expensive it's outta my budget T^T -
$1399 is a little too steep considering their flagship G73 is only $1599 or so. -
Who will win in a fight between N82 and 4820T rawr ! -
not sure if it's been posted, yet, but...
ftp://ftp.asus.com.tw/pub/ASUS/nb/N82
pretty generic info, but at least it's info, right?
if you go up one level ( ftp://ftp.asus.com.tw/pub/ASUS/nb/) you can find lots of 'stuff' for different models -
I hope this laptop will be out during March !? It's very long...I didn't find other laptop as good as this one.
I removed from my list a lot of laptop for different reason and this Asus is the last one.
I removed Sony CW27FX : Not available in canada (only with g310m offer here)
I removed Lenovo Y460 : Seem to be very hot ! I want to use it on my palm in the train !
I removed Sony Z : Little hot too, expensive, small screen (13.1) and prefer large hd than SD for the moment. No blu-ray player for the price !
Asus N81 still interest me, but too expensive (1100$ on amazon.ca) for an old model (if the N82 is only 200$ more when it will be out, it's not a good deal to buy N81), and the keyboard it too hot on the N82 with space between keys and Optimus technology to have better battery life. -
-
Since I have a trip coming up I couldn't wait and so I caved and bought the new Z series.
Hope the N82 is worth the wait guys... I'm sure it'll be awesome. -
Yeah not presently, but on the header of Lenovo Canada, we can see the Y460 with a video ! Probably it will be available soon.
-
As for the Y460.. earlier I called Lenovo Canada, and the rep told me that there is no plan in the near future to bring that model over -
What about the Envy 15 2nd Generation? The i5 spec and $300 USD coupon brings it down to $1250 USD.
Note that it does not come with an internal optical drive and the webcam is a little spotty.
Still, you get an i5 CPU and ATI 5830 GPU in a laptop that is 1 inch thick, 5.17 lbs, 15.6 inch screen with 1920x1080 resolution. The i5 spec is very cool to the touch (i7 is warm) as it has 3 fans inside.
All again for only $1250 USD.
-
-
Ouch! Someone in the Czech Republic said the Envy was $2500+ USD over there.
There are times I thank my lucky stars to be an American (or at least living in the USA).
-
-
Double ouch!!!
Look at the bright side: at least you've got curling!
-
-
Triple ouch!!!!
I have to think that all these countries are imposing trade tariffs, duties, taxes, etc. on goods like laptops and the like. These tariffs are translating into higher prices for those countries consumers (all in an attempt to prevent an outflow of cash and restore trade balance between imports and exports).
I can't imagine companies like HP hiking its prices in foreign countries just to alienate more potential customers. It's to their advantage to sell as many products as they can across the world.
Tell your politicians to lower tariffs and fees on imports!
-
Bronsky -
Good point there. I hadn't thought about that.
I prefer having cheap computers. After I grow old and retire, raise the tariffs and taxes on imports (like PCs). I want my free healthcare!
-
Sounds like a campaign to me
.
-
My laptop's finally up and died... won't boot up into Windows... when will this stupid thing get released!?!?
-
Are you sure it's not just the disk drive?

N82Jv will be available for sale starting next week, in Malaysia...
