Introduzione

Stiamo per smontare il più nuovo (e grande) iMac nella serie di Apple: l'iMac da 27"! Abbiamo smontato questo iMac in data 21 ottobre 2009.

Vuoi gli aggiornamenti dell'ultima ora? Segui @ifixit su twitter.

Guarda lo slideshow video super veloce dello smontaggio! Ha della musica con banjo!

Questo smontaggio non è una guida di riparazione. Per riparare il tuo iMac Intel 27" EMC 2309 and 2374, usa il nostro manuale di assistenza.

  1. Non abbiamo badato a spese per portarti il più recente e il più grande degli iMac. Abbiamo nel nostro studio il più ingombrante iMac che si può comprare. Il nuovo iMac fa impallidire l'iMac da 20" che abbiamo smontato precedentemente quest'anno.
    • Non abbiamo badato a spese per portarti il più recente e il più grande degli iMac. Abbiamo nel nostro studio il più ingombrante iMac che si può comprare.

    • Il nuovo iMac fa impallidire l'iMac da 20" che abbiamo smontato precedentemente quest'anno.

    • La caratteristica più distintiva di questo nuovo iMac è il nuovo schermo da 27" retroilluminato a LED. Lo schermo vanta una risoluzione 2560x1440 in formato16:9.

    • Nella confezione è presente anche il nuovo Magic Mouse. Lo abbiamo già smontato.

    • La maggior parte delle immagini promozionali di Apple mostravano l'iMac in funzione e senza cavo di alimentazione. Sembra molto più bello così, ma, sfortunatamente, la nostra unità deve essere attaccata alla corrente per potersi accendere.

    I'm missing unboxing step what is inside etc.

    Thanks for nice work !

    Brilliant teardown. Couple of points;

    1. Is there a "spare" SATA connector, and what would it take to add an external port ? From your earlier posting I think there's room on the back panel.

    2. Cable management - and this has always been a bugbear on the whole iMac range - why not cut a slot in the stand to feed all cables through for neatness ?

    3. Have you tested the HDMI input, and what does it look like ? Would you watch TV on this with the addition of a USB tuner ?

    4. Let's see it go back together...:-)

    Seriously, fantastic teardown. I showed the Mrs and she hit me, yelling NO, NO... go figure...

    I too am wondering if an eSATA port can somehow be added. To me, that's the biggest thing that's missing from the latest Macs. I've heard about the forthcoming Apple/Intel Light Peak optical interface but nothing is going to beat native SATA for an external storage interface (no bridge/translation necessary).

  2. Nove porte. Queste sono identiche alla scorsa revisione, ma la Mini DisplayPort ha un nuovo asso nella manica.
    • Nove porte. Queste sono identiche alla scorsa revisione, ma la Mini DisplayPort ha un nuovo asso nella manica.

    • Questo iMac supporta una nuova funzione che ti permette di trasmettere un segnale video da fonti esterne allo schermo interno. Apparentemente, serve per collegare il tuo lettore Blu-ray, in quanto la macchina ancora non ne include uno interno.

    • Sfortunatamente questa funzione richiede un adattatore. Dove è l'adattatore? Non nella confezione. Il manuale dice "I cavi e adattatori richiesti sono venduti separatamente". Non che la cosa ci lasci sorpresi, il solo cavo che c'è in confezione è quello di alimentazione. Già, Apple pensa che i cavi siano una creazione del diavolo.

    Why is the 21.5" iMac does not have video-in capabilities? What is the difference in those two MotherBoards?

    Vrumm - Replica

    The option that I can see is to be able to plug in a second monitor and or connect it to the TV for a nice large screen

  4. Puoi ora installare un'enorme quantità di RAM, 16 GB, nel tuo iMac! Con una mossa davvero benvenuta, Apple ha raddoppiato il numero di porte, permettendoti di installare quattro banchi da 4 GB PC3-8500. Ovviamente, dovevamo vedere coi nostri occhi. Apple non stava scherzando, se hai i soldi, puoi davvero avere 16 GB di RAM nel tuo iMac! 16 GB ti faranno spendere 1400 $ da Apple, o 400 $ da noi. Ovviamente, dovevamo vedere coi nostri occhi.

  5. Il nuovo iMac include un vetro da bordo a bordo. Questo è diverso dal bordo in alluminio di 4 mm che circondava il vetro sui precedenti iMac. Speriamo Apple abbia inserito dei magneti abbastanza forti per tenere fermo il vetro. Dopo aver aggiornato la RAM sul nostro iMac, abbiamo notato che il vetro era leggermente disallineato su un lato. Due ventose, due mani ferme, e l'enorme pannello in vetro si solleva.

    There have been a number of reports on the Apple forums of the glass being broken on the bottom left side. If you have an Apple store nearby, you can ask them to replace the glass (they will have to get the replacement glass shipped to the store), otherwise call Apple support to obtain a replacement machine.

    Actually, in both photos the suction cups are attached to the glass. The display is recessed about .125" below the glass panel, and the two components are not connected. To remove the glass, lay your iMac stand-side down on a table. Stick two suction cups along the top edge of the glass and pull it away from the rear case of the iMac. Rotate the top edge of the glass panel slightly away from the rear case of the iMac to clear the mounting pins, then slide the glass toward the top edge of the iMac to free the flat tabs along its lower edge.

    • Il pannello LCD prodotto da LG pesa quasi 5 Kg! Quindi, di nuovo, è una bellezza massiva da 27".

    • La risoluzione è davvero impressionante: 2560x1440. Questa è la stessa risoluzione di uno schermo Apple Cinema da 30"!

    • Lo schermo utilizza la tecnologia IPS, fornendo un angolo di visione più ampio e una migliore riproduzione dei colori della più economica TN.

    • Il pannello è molto lucido. è perfetto per spiare chi sta dietro di te oltre che per guardare dei film.

    • Sembra il numero modello sia LM270WQ1. Una ricerca su Google di questo modello attualmente mostra cinque risultati, e solo uno di questi in inglese.

    24" iMacs had matte displays (model identifier iMac6,1) when first introduced (all white)...one of two reasons I haven't upgrade my 6 24"iMacs.

    The other reason Bluetooth full size keyboards (model A1016, white) are only available today with a USB cord. I don't have the specs on the new cabinet width, but the 24" iMac: is nearly 23" wide. A 17" wide, full size keyboard is too big to put in front of a 27" iMac?

    Progress?

    BobForsberg - Replica

    I agree on the lack of a numerical pad--disappointing. I wonder how long until someone does an indepth review of that display? LED IPS displays are $$$ especially if this one renders color as well as some of the other high displays. That makes the price of this machine so much more reasonable.

    LED Display - is it RGB LED? Is it side lit or back lit?

    wkchan - Replica

    Citazione da wkchan:

    LED Display - is it RGB LED? Is it side lit or back lit?

    RGB LCD with LED backlight. It is not an OLED display, which is a common source of confusion (OLED vs LCD, LED backlight vs CCFL).

    Diggsby - Replica

    Citazione da Diggsby:

    RGB LCD with LED backlight. It is not an OLED display, which is a common source of confusion (OLED vs LCD, LED backlight vs CCFL).

    Hmmm ... my origin question was not too clear.

    I meant to ask:

    1. if the LED backlight uses "RGB/tri-color" LEDs or just "white" LEDs (as in the MacBooks).

    2. if the LED backlight on the edge of the display or the back of the display.

    LG makes a 1920x1200 17.1" LCD panel, LGD01b3, with RGB LED backlight, edge-lit. The LGD01b3 display has a wide color gamut, high contrast with vivid colors but suffers from non-even backlight color (I call it "wild gamut" because I can never get the color profiling right).

    Cannot find any info on this LM270WQ1 LCD panel and was hoping that the Teardown guys can tell if the backlight uses RGB LEDs and if the panel was edge-lit.

    This LCD panel is IPS and if it also uses RGB LED, then the iMac 27" is really a price break through!

    But on second thought, went through the specs and never see "wide gamut" being mentioned -- so likely at this price point, it is likely just a white-LED backlight.

    dotm8rix - Replica

    OK, I still don't think we have a definitive answer as to how the new displays are actually "lit". Has it been confirmed whether the screens are edge-lit or back-lit?

    Also, regarding some recent display anomalies... I've been involved in a few discussions over at Ars Technica [URL=http://arstechnica.com/apple/news/2009/1...]here[/URL] and [URL=http://episteme.arstechnica.com/eve/foru...]here[/URL].

  8. Questo non è bello come il davanti, ma ci sono alcune cose degne di nota qui.
    • Questo non è bello come il davanti, ma ci sono alcune cose degne di nota qui.

    • Ci sono quattro cavi che collegano il pannello LCD all'iMac:

    • DisplayPort

    • Sensore della temperatura

    • Retroilluminazione LED

    • Sincronizzazione della retroilluminazione LED

    • La cosa importante da notare è che non c'è nessuna scorciatoia speciale dal connettore Mini DisplayPort allo schermo. Il segnale deve passare tramite la scheda madre, quindi dovrai avere il tuo iMac acceso se vuoi mostrare a schermo le immagini da una fonte video esterna.

    Re: Mini DisplayPort, you write:

    > you'll need to have your iMac powered on if you want to

    > display from an external video source.

    This means "powered on and running OSX", right?

    So, this iMac won't become a decent second display if the logic board goes south, or after quad 2.66GHzs are no longer "fast enough" to read email on?

    I found the flat cable (display to motherboard) easier to remove (and, more importantly, to replace) if I first removed the tape from the back of the display and disconnected the cable from that end instead of from the end that connects to the motherboard.

    There should be a 3.5" drive with both an SSD and a high capacity HDD on it (dual SATA). The SSD wouldn't need to be that big, say 32 or 64GB , since the most active files and swap space would reside there. I guess it would only apply to the iMac though.

    Given how much the SSD in my MBP has sped things up, I almost feel installing an SSD in a new iMac is a necessity.

    You can maybe use SATA port multiplier and, from photos, I would say that there is enough space for 2,5" SSD behind GPU heat-pipes ? right ? (although maybe it is not best idea to put SSD close to heatpipes :D)

    I'd like to try the following:

    SATA 1: 120GB OCZ Vertex SSD

    SATA 2-> port multiplier

    1: 120GB OCZ Vertex SSD

    2: SATA to eSATA and thread out cable from iMAC

    Then put the SSDs in software RAID 0 and still have a nice eSATA port coming out...

    Of course this would require the SATA controller to support port multipliers, any idea what chipset it is??

    Why did you ignore the Electrolytic Capacitors and their values?

    These caps are the components most prone to failure.

    This is especially true of PS built in the latter part of the 2000 decade. Somewhere around 2006 - 2008 the electrolytic capacitor supply chain was flooded with caps with a built-in failure mechanism due to being made with incomplete data from industrial espionage gone wrong. My Late 2009 iMac PS failed and its capacitors showed the physical signs of this failure mechanism. Replacing caps is easy and cheap. I had a VISIO Television that had the bad caps and failed. It cost $15 to repair a TV that originally cost just under $1,000.

For example, midplane board, hard drive, RAM, etc. Funny thing is that people still needed help simply installing RAM! Apple rethought this strategy, because subsequent iMac models did away with this clean internal design (and so many user-installable parts).

    I'll take that flame bait, but not hook, line and sinker...

    First of all, you must be easily amazed, because Apple has always had higher premiums on their components. They can only leverage their monopoly on stuff like NAND flash memory prices.

    Not a "magic" WD hard drive, but neither are the Seagate drives (their other drive supplier). Apple generally maintains more strict product tolerances from vendor for things like RAM latency, hard disk burn-in and MTBF. This usually means Apple staff "qualifies" goods before getting them into your hands. This adds to cost--esp if Apple has their own special recipe of firmware to drop onto drives (e.g. server-grade drives).

    Ok, I'll stop there.

    All Mac users missed the myriad adverts touting "2TB hard drives only $179!", because we're ignorant Mac zealots.

    @Chris - the intent of my post was to take the pi$$ out of what appeared (to me) to be Mac flame-bait from. "Mac zealot" was a self-depricating reference to steal Joe C's "thunder" if/when using said term himself.

    The point is that life is not as black and white as "I'm a Mac"/"I'm a PC"--as Joe C insightfully points out in his later post re: "PC" definition. Apple's and Microsoft's ad campaigns try to stoke this outmoded argument. We know how common it is for people to work on Windows PC at the office and Macs at home.

    But "PC" statistically refers to Windows PCs (given the slight market share Linux has).

    Concerning C2D Quad-core replacements:

    After looking at the CPU specs in detail for the E7600 and E8600 C2D parts and comparing them to the various available C2Q parts, it seems to require one of the 45nm QxxxxS parts to even have a chance of working, with the Q9505S or Q9550S being the most likely of the higher-end ones. The power regulator specs/etc. are different for the non-S parts.

    I'd be happy to try it, pretty sure the worst thing that will happen is that it won't boot due to lack of C2E (Stop-Grant) support or confusion about having 4 cores instead of 2. It could also come up but refuse to recognize the other 2 cores.

    I'd be happy to try it, pretty sure the worst thing that will happen is that it won't boot due to lack of C2E (Stop-Grant) support or confusion about having 4 cores instead of 2. It could also come up but refuse to recognize the other 2 cores.

    Hmm. Is a Q9550S CPU the only thing that you are lacking?

  22. rimuoviamo la scheda figlia della GPU. Il nostro modello base da 27" include un processore grafico ATI Radeon HD 4670 con 256 MB di di memoria GDRR3. L'enorme quantità di etichette sul retro della scheda figlia della scheda madre è opprimente. Ma che cosa stavano pensando?

    it's possible to remove graphic card and replace it with the same but 512mb vram?

    I'd be interested to know if you can replace it with a better one. You say these are generic parts? Where can we get them? Or are they only available to manufacturers?

  23. Questa antenna porta al retro del logo Apple? Noi lo supponiamo... ti stai chiedendo perché?
    • Questa antenna porta al retro del logo Apple? Noi lo supponiamo... ti stai chiedendo perché?

    • Il logo Apple non è solo per l'estetica: ora ha un compito preciso. I precedenti iMac avevano la parte anteriore in alluminio e la posteriore in plastica. Questo ha una copertura tutta in alluminio, fantastica per l'aspetto, ma terribile per il WiFi. Il logo Apple è l'unica zona in plastica dell'iMac, e Apple ci ha integrato un'antenna AirPort.

  24. Dopo uno smontaggio così noioso, non puoi incolparci per aver impilato il tutto in una mostruosa catasta di componenti.

Can anyone confirm if it would be possible to feed a SATA cable into the Memory Door area, thus allowing the cable to exit via the memory door opening? I can't tell from the pictures if there is enough room to get the cable into that area and then out the door. Obviously with the door removed the cable would feed out so it's more a question of getting the cable into that area. Then I could modify the door to allow the cable to feed out while still remaining closed.

Apple has the option for both a Serial ATA Drive + a Solid State Drive. How do both of these drives fit into the enclosure? Can you add the second after purchase?

Mark - Replica

That would be interresting to know. Sounds like it would be quite easy to add this SSD later.

hey i have one iMac late 2009 27'' model, with ATI Radeon HD 4850 512 MB GPU, and a 2.66 GHz Intel Core i5 CPU. do you guys know how i can upgrade them, (if possible)? I don't care about the warranty cause it's expired anyway

Just curious if anyone has ever taken apart an iMac and used it's guts to create another pc without the internal display?

Paul Garcia - Replica

Paul,

That's an interesting idea (forget the internal display and use the rest in another case with a stand-alone display connected through the Displayport/Thunderbolt port). Just so happens I have an iMac with bad internal video (black screen, only two LEDs on motherboard lit). I'll try plugging in a Displayport display I have here and, if the unit actually works, I'll start the disassembly and re-packaging using a spare PC case I have in my garage. Nice project idea!

Thank you for details and wit.

• Step 5 - yah, I found the magnet that's in the upper LH corner by accident (I use it to hold documents with a paperclip when I need to reference them when typing..).

• Step 7 - Yes, the screen is VERY glossy! Contrary to some beliefs re: placement of a desk, I tried placing my desk such that I'm facing the door, but my back is to a window.. turns out that I don't miss out on seeing what's going on outside after all.

hello,

I have an old mid 2010 iMac 27” i7, which I upgraded with a SSD. It works perfectly but I have problems in data transfer. I want to know if I can use one of the internal SATA ports (that of the Super Drive or another spare one) to come out with a USB 3 port. Thank you for your Help
