Takeaway: The Asus Eee Pad Transformer Prime is a solid Android tablet, but its case is tricky to open and quality control during assembly needs improvement.

In April 2011, Asus released the Eee Pad Transformer tablet. Less than a year later, the company rolled out a redesigned, quad-core version of their Android tablet–the Asus Eee Pad Transformer Prime.
In this week’s episode of Cracking Open, I show how to open the Transformer Prime without damaging the front panel and what’s inside the device. I also explain why Asus needs to improve quality control during the manufacturing process.

Our Transformer Prime has a quad-core Nvidia Tegra 3 processor, 1GB of DDR2 SDRAM, 32GB of flash storage, a 10.1″ WXGA IPS+ LCD (1280 x 800), 802.11 b/g/n WLAN and Bluetooth 2.1 EDR, 1.2MP front-facing camera and 8MP rear-facing camera. The Prime measures 7.1″ (H) x 10.4″ (W) x 0.3″ (D). It weighs 1.3 pounds.

Cracking Open observationsTrick to opening the Prime: The front panel (digitizer) is held to the aluminum case with a series of plastic tabs (which you can pop loose) and eight plastic posts (which you can’t pop loose). The posts are held in place by two internal locking mechanisms. To avoid breaking the plastic posts, you must slide these mechanisms into their unlocked position. First, you’ll need to remove two rubber plugs along the device’s bottom edge. Inside each stopper hole, you’ll see a circular indention. Insert a thin tool with a pointed tip into the indention and slide the catch sideways. If you’re holding the tablet face up, slide the catches to the right. Once you’ve unlocked both mechanisms, you can use a thin metal blade or plastic case opening tool to pop loose the front panel’s remaining plastic tabs.

- Clean internal layout, but why all the yellow tape? The Transformer Prime’s internal hardware layout is clean and well-organized. Unfortunately, Asus also used a lot of yellow tape throughout the device. Practically every connector is covered with a piece. This makes me wonder about how well they would hold on their own.
- Quality control problems during assembly: Asus appears to have quality control problems with the device’s assembly. Our test unit’s battery and LCD each had two empty screw holes.
- Little metal shielding on motherboard: There is almost no metal shielding on the the motherboard. Perhaps the Prime’s aluminum case provides enough protection from electromagnetic and radio frequency interference, but it’s still odd to see so little shielding.
