“We awarded the 2nd generation Apple TV a coveted Repairability Score of 8 / 10 due to its ease of disassembly, minuscule power consumption, and highly recyclable construction,” iFixit reports.

“After three years, Apple has finally released an updated revision of its revolutionary streaming home theater device, the 2nd generation Apple TV, powered by the Apple A4 processor,” iFixit reports. “With such small dimensions, 0.9″ x 3.9″ x 3.9″, and a mere weight of 0.6 lbs, no wonder it’s been dubbed ‘The Puck.'”

“The backside of the Apple TV [contains an] HDMI output port, Optical audio out port, 10/100 Base Ethernet port, AC adapter port, [and a] Micro-USB (for service and support),” iFixit reports. “Apple is continuing its theme of hiding power supplies inside their devices. It’s especially impressive here, considering that the Apple TV is only slightly larger than a 60 watt MacBook AC adapter.”

“The solder pads near the side of the logic board look to be a *perfect* match for a dock connector!” iFixit reports. “This Apple TV seems to be a couple of connectors shy of a full-on computer. Perhaps this logic board will be used in future iPads?”

iFixit reports, “What is this? A Samsung K9LCG08U1M 8GB NAND Flash chip? Why, yes it is. It’s the same part we found during the iPad teardown! This is a pretty remarkable amount of storage for a $99 device. We are pretty sure the Sammy is used to cache your favorite shows while they’re being streamed. But we wonder, What else you could do with 8 GB of exploitable storage?”

“Wi-Fi board brought to you courtesy of Panasonic! This may be the first time we’ve seen a Wi-Fi board from Panasonic in an Apple device,” iFixit reports. “The Broadcom BCM4329XKUBG 802.11n Wi-Fi/Bluetooth/FM chip on the Panasonic board is exactly the same as the one we found on the iPad.”

“The key marking of interest on the A4 processor package is K4X2G643GE. This is identical to the marking found on the iPad and 4th Generation iPod Touch, but different from the iPhone 4 processor,” iFixit reports. “The Apple TV has 256 MB RAM, the same as the iPad and 4th Gen iPod Touch. We weren’t expecting Apple to bump up the RAM, but it’s a bit of a relief for app developers that the amount hasn’t been reduced.”

“The sticker on the power supply has this rating: 3.4V @ 1.75A,” iFixit reports. “We’ll save you the multiplication: that’s just 5.95 watts! Is this the most eco-friendly set-top box ever? …Apple brags that when in standby mode, the Apple TV uses less power than a night light.”
