    TechRepublic's Bill Detwiler cracked open the Apple iPad for a look at the hardware inside the Apple tablet. You can also watch a video of the process in the TR Dojo blog.

    In addition to photos from Bill's experience, we've included a few photos from iFixit and Rapid Repair.

    I strongly encourage you to check out the iPad teardown galleries on their sites for more photos.

    The Apple iPad's box is surprisingly think for such a thin device.

    Removing the box top, give us our first look at the Apple iPad.

    Within the box, we found the Apple iPad itself, a USB wall power adapter, standard Apple docking cable, a bit of documentation, and a few Apple logo stickers.

    As with the iPod Touch and iPhone, cracking open the Apple iPad began with me sliding a thin metal blade between the glass front panel and the metal case. The front panel is secured with small metal clips that are screwed to the underside of the front panel. You'll find these clips along the top, bottom, and left side of the front panel. The right side has hard plastic tabs that fit into slots on the metal case.

    Yes. That is a spatula you see on the table. Its extremely thin, flexible metal blade was perfect for slipping between the iPad's metal case and front panel.

    With the tabs popped loose, we can gently separate the front panel from the case, but not completely.

    There are three cables that connect the front panel to components within the metal case.

    One short ribbon cable, connects the ambient light sensor to the main logic board. A second, thinner ribbon cable connects the digitizer to the main board. And a third thicker cable connects the display and LED back light to the main board.

    With the two ribbon cables removed, we get our first look inside the Apple iPad. Wow! Look at those batteries.

    The front panel contains the 9.7-inch (diagonal) display, LED back light, digitizer, ambient light sensor, and Home button.

    Within the Apple iPad's metal shell, are the main logic board (mostly covered by a metal EMI shield), the batteries, Wi-Fi and Bluetooh card, antennas, headphone jack, microphone, speakers, On/Off button, volume up/down button, and screen rotation lock switch. On 3G model (to be released in late April), you'll undoubtedly find additional cellular components.

    The Apple iPad's 3.75V, 24.8 watt-hour battery provides the power for an advertised 10 hours of average use.

    In the top, right-hand corner of the metal case you'll find the on/off or sleep/wake button, the screen rotation lock switch, and the volume up/down button.

    At the bottom of the metal case, you'll find the speaker assembly, two speakers, data port, connector pins for the Home button, and one of the antennas.

    The large connector that runs down the center of the battery assembly, attaches the components at the bottom of the iPad to the main logic board at the top.

    With the iPad's speaker assembly removed, you can see the two speakers, which face toward the metal case.

    You must remove the thin metal shield from the main logic board to see the Apple iPad's processor and memory chips.

    With the metal shield removed, you can see the Apple iPad's A4 processor, two large Samsung NAND Flash memory chips, a Broadcom I/O controller, and chips from Texas Instruments and NXP.

    The markings on the A4 processor are:
    N26GUOF 1007
    K4X2G643GE JGC8
    APL0398 33950084
    YNL185A3 1004

    The markings on the Samsung chips are:
    952 K9LCG08U1M-LCB0
    FAKG08X1

    The markings on the Texas Instruments chip is:
    CD3240A1
    02A0KET?C1

    The markings on the Broadcom I/O controller are:
    BCM5973KFBGH
    HS0951 P11
    951295 B1

    The markings (at least those I can see) on the NXP chip are:
    L06
    01
    ZSD951

    This connector did not have a cable attached to it on our iPad. Perhaps it will in the 3G version released in late April.
