Yup. Leaking Aluminium Electrolytic Capacitors (http://www.repeater-builder.com/motorola/spectra/spectra-caps/c635+c636.jpg) on the motherboard (sample picture only).
Replace them with Tantalum Electrolytics or disconnect the speaker. If you don't replace the capacitors, eventually they will corrode tracks on the motherboard (if they haven't started already).
A slight warning about the caps replacement - Id recommend doing it carefully, you really dont want to ruin the board if you slip. Also check PDS slots still work post-op if/when you replace them :)

see this youtube video and you will be able to determine whether CPU affects the overall speed more than GPU. This guy compared 11" MBA(with 320M graphics) and 13" sandy bridge MBP with SSD(with Intel 3000HD graphics )
http://www.youtube.com/watch?v=Qp720fEnuRs
Of course sandy bridge MBA won't use full power sandy bridge. But you will know that MBA's performance is just overpraised by SSD, not by GPU. Once other notebooks get SSD, MBA's benefit is only limited to small form factor and weight.(maybe + high resolution)
I just don't understand people overpraising 320M on MBA, this made me to join here.
2GB RAM = Apps will probably have to use the paging file = slower.
But yes, the additional power of the i-series CPU will inevitably beat the GPU's power for most tasks. Gaming is another question altogether.
People who want to keep the 320M are mostly people who want to do light gaming on their Airs.

As a mechanical engineer, I'm not exactly cynical about this application of Eneco's technology, but I remain very, very skeptical. With such a relatively small temperature difference, I would say it is very unlikely that such a device would be economically feasible. A quick visit to Eneco's site shows me that they don't even have lab data for temperature differences of less than 100 deg C!
They obfuscate the issue of efficiency by referring to the Carnot efficiency to inflate the numbers to the uninitiated. Sadi Carnot showed that an ideal heat engine that operated between two infinite reservoirs at temperatures, T(hot) and T(cold) would have an efficiency of ( T(hot)-T(cold) ) / T(hot), and the temperatures have to be on an absolute scale like Kelvin or Rankine. The "Carnot efficiency" compares the performance of the system in question to this ideal heat engine.
Suppose you ran your chip at a very warm 90 deg C (363 K) and could dump the heat to your 25 deg C (298 K) room, your perfect efficiency would be about 18%! This means that for every 5W of heat you dissipate from the chip, you get a little less that 1 W of electric power. Something with an impressive-sounding 50% Carnot efficiency would really have a measly 9% real efficiency.
Unless Eneco sells these things very cheaply and makes them very small, I can't see Apple going through the trouble and expense of adding them to their portables for such a small benefit in recycled power. I remain skeptical, yet open-minded.

i'll be getting more involved with this as soon as my electricity supplier has finally changed, should be a couple of weeks, my current love overcharging me for leaving things running 24/7.
At least you can change providers, at least where I live there is only one so I'm stuck with what I have to pay:(
i'll also try and sort out the software for my ps3, i barely use that so it'd prolly out do my computer looool
Powermac G5 dual 2.0Ghz teh Mac Pro is coming later this year hopefully :D
Ps3's are quite fast when it comes to folding so it may indeed outpace your G5 :p

They're getting rid of the light in lion. They don't want the average user worrying about "open" or "closed" apps. Just use and exit when done. The system will worry with open and closed. I like it that way.
Auto save, resume, saving state is the future of multitasking for all Apple products.
Actually there is an option to turn the indicator light on, in System Prefs. I think quitting, closing and opening apps is perfect the way it is.

...I bought a Wii because of the virtual console games from old systems and the Zelda: Twilight Princess game available at launch. It was also $250 at the time versus like $400 and $600...
I bought the wii for the same reason you did, 250 is much cheaper than 400-600 and the virtual console sounded like an awesome idea.
I bought an xbox when it dropped to 200 and haven't touched the wii since. Also, the xbox live arcade games (a lot of them are also on the PSN) trounce the virtual console games.

Does nobody realise that you have to support the exFAT format (from Microsoft, currently NOT supported on OS X, and has to be licensed by Microsoft) to be able to use more than 32 GB? (or the up to 2 TB). Otherwise if you format it with the old formats you are stuck on the same limits as you would with ad SDHC card..
Sort of.
Lets separate reading and writing exFAT. If I can read it, I can pull stuff off of it. So OS X will require the ability to read exFAT in order to make it compatible with non apple devices that will be using this format. HOWEVER, it is not required that Apple choose to read exFAT. You could format with HFS+. Then any device that can read HFS+ could read and write to it.
If I can write to exFAT, then I can place data (even 4GB+ media files) on the card. Apple may create a driver that allows you to read exFAT but not write to it.
This matters if you are going to use the card to store media files (4 GB+), or are planning on using the card with non Apple devices. I could get a 128 GB SDXC card, format 100 GB in FAT32 for a user directory, and format 3 8GB swap spaces (one for OS X, one for Windows, and one for Unix). Then I'd have my user files and swap space with me wherever I go, and it would be cross platform compatible (everyone reads and writes FAT32). Yes, FAT32 does have a maximum partition size, this is why I used a 128 GB SDXC card as the example. And yes, I wouldn't have my media files (movies) on the card (I'd need one of the 2 TB cards to do this).
Since Pretec is selling an ExpressCard SDXC reader, this is what I plan to do with my triple boot MBP (see sig). I'll point my OS X user directory to the directory that will be on this card, I'll do the same for Win7, and BackTrack. Each OS will also have swap space on the card. This increases security too. If I have my SDXC card with me, someone using the laptop can't see my files at all. It also increases speed (maybe and a little) because I'm using a different storage device and bus to put my user files/swap space on.

hey i dont know about both MB and MBP being updated at the same time.
Not sure if it would make sense. there are limited Core 2 Duo's available. As Imac has sold well with it. If Apple had decided to use Core 2 Extreme in the Imac. instead of the Duo, then i would agree with all of you thinking that the MacBook would be updated now.
But to be honest, at the moment, i am not sure if it would make sense. I see apple only doing MBP immediately, they need to prove a reason for the power, more than the card slot, graphics chip and different case.

The above three posts are my best effort translating. That PC guy talks insanely fast. ;)
A very nice job on the translations. Besides generally knowing what they were saying (as everyone else could, since we knew the English), I couldn't pick up anywhere close to what you got. However, on the "uiurus" one, the second to last line should start
???
??
Anyway, as I was rolling thru the posts, I saw that someone already identified the "art of eating sushi" video they did. If anyone cares, they are a comedy duo called Ramens ???? and they have another video that is google-able about the art of apologizing. Not as good, but still funny. There are also a couple of other Flash(?) skits they do (at least it sounds like them...it is just (minimal) animation) riffing on Tokyo train station names (called kyoubashi ??) and on prefecture names (ibaraki ??) that are amusing. Especially if you see yourself in that particular language class.

I was maybe 300 in a line of 500+ at Willow Bend Mall. Waited 5 hours, got to spot 50 from the door, and they ran out.
The sad thing was the lack of information being provided by Apple to us waiting in line. There were maybe 150 in line still when they clearly ran out. The line sat unmoving for about 45 minutes when news was finally announced that they ran out. I don't understand why they had us stand there for 45 minutes to tell us they were sold out?
During past launches, Apple passed out free water, or took inventory counts against the people waiting in line. This time nothing from Apple but a bunch of Apple employees that had no idea how much inventory they had until they were all out.
I don't know why they didn't allow pre-reservations, either, this time around.
So this launch, in my opinion, was a little wild and disorganized compared to launches of days past.
They passed out water at Willowbend at least at the front of the line.

That sounds good enough to me and the millions who will buy it.
There isn't a single added feature listed there to make it worth the extra ~$100 to get a new iPhone instead of the identical iPhone 4 at discount.
