This guide has been found to be exceptionally cool by the iFixit staff.
While Google hosts a scavenger hunt, iFixit has taken a step further and uncovered our own treasure, the Samsung Series 5 3G ChromeBook.
Has Google changed much since the prototype Cr-48 Chromebooks were sent to developers late last year? Join us as we reveal the inner-most secrets of the Series 5 3G ChromeBook.

Samsung Series 5 3G Chromebook Teardown
¶
The Samsung Series 5 Chromebook is the first ChromeOS notebook offered to the public.
It features:
A 1.66 GHz Intel Atom N570 Processor and integrated Intel NM10 Graphics
2 GB of non-upgradeable DDR3 RAM
12.1" Matte LED-backlit LCD display
16 GB internal SSD
802.11 b/g/n Wi-Fi and Verizon 3G WWAN connectivity
SD card reader and two USB ports

Edit
Step 2
¶
Along the left edge lies the power connector, fan vent, rubber door for Mini-VGA and USB ports, and a headphone/microphone jack.
The SD reader is on the front left face of the machine for all you shutterbugs and mini-storage freaks.
Finally, along the right side is the door for a USIM card and another USB port.

Edit
Step 3
¶
Before we start tearing this device apart, let's do a little comparing to Google's previous developer-only Chromebook, the Cr-48.
The outer exterior of the Series 5 is much more elegant than its ancestors, and a bit slimmer as well.
The Cr-48 scores bonus points for repairability with its removable battery.
Both feature nearly identical keyboards, and playing around with the machine for a bit revealed that the Series 5's trackpad is an improvement from the Cr-48.
Sadly, Samsung's legalese-speaking technical writing department made their safety instructions much more boring than those included with the Cr-48.
Enough jabber, let's crack this thing open!

Edit
Step 5
¶
We decided to pop open the Cr-48 to see how it compares to the new Series 5.
The similarities include:
Separate motherboard & I/O board layout with mini-PCIe cards for WWAN, Wi-Fi, and flash memory.
Intel NM10 graphics cards are used in both machines.
The major differences are:
The Cr-48 has removable/upgradeable RAM, while the Series 5's RAM is soldered to the motherboard.
The Cr-48's battery is accessible from the outside of the machine, while the Series 5 must be cracked open to swap out the battery.
The Series 5's Atom N570 processor sports dual cores with a total of 512K more L2 cache than the Cr-48's single core Atom N455.

Edit
Step 6
¶
The Series 5's massive (albeit thin) battery can be removed after twisting out three Phillips screws and disconnecting it from the motherboard.
The Samsung-manufactured lithium polymer battery is good for 8.1 Amp hours at 7.4 V!
Coupled with the Series 5's low-power Atom processor, the battery is good for 8.5 hours on a charge.

Edit
Step 8
¶
Big players on the Qualcomm Gobi2000 WWAN board include:
Qualcomm MDM2000
Samsung K4X56323PI 32 MB Mobile DRAM
Qualcomm RFR6500 receiver
Qualcomm RTR6285 UMTS transceiver with GPS

Edit
Step 10
¶
After removing its mounting screw, the 16 GB SanDisk SDSA4DH-016G SSD can be removed from the motherboard.
This is the same SSD used in the Cr-48.

Edit
Step 11
¶
Removing two screws frees the miniscule heat sink from the Atom processor.
The Atom processor and NM10 graphics chip produce such little heat that no cooling fins are used at the fan's exhaust. Air forced over the thin copper plate comprising the heat sink and fan shroud bottom by the fan blades is enough to keep things cool.

Edit
Step 13
¶
Front and rear side of the motherboard:
1.66 GHz Intel Atom dual-core N570 processor
Intel NM10 Express Chipset (labeled as CG82NM10)
Realtek ALC272 4-Channel High Definition Audio Codec
Samsung K4B2G0846 HCH9 2 Gb DDR3 SDRAM (total of 8 IC's = 2 GB RAM)
SMSC MEC1300-NU
SLG8SP513V clock generator
SMSC EMC2112 Fan controller

Edit
Step 14
¶
At this point, not too many interesting components are left in the Series 5's chassis.
The I/O board can be removed at this point, and it isn't all that appealing. It simply serves to transmit information from the motherboard to the mini PCIe communication cards, USIM card, USB port, and right speaker.
The speakers are held on with little strips of tape and can be removed at this point. No word on how they sound just yet but judging by their diminutive size and fabric domes, they probably won't be popping eardrums anytime soon.
Removing the SD card reader reveals the widely-used Realtek RTS5138 SD reader IC.

Edit
Step 16
¶
Samsung Series 5 3G Chromebook Repairability Score: 6 out of 10 (10 is easiest to repair)
SSD, Wi-Fi, and WWAN, and most other components are individual modules that can be replaced independently
Display is very easy to remove
Mostly-plastic construction feels a little cheap
RAM is not replaceable
Battery cannot be removed without opening the case
