iFixit Surface Pro Teardown Reveals Impressive Battery, Poor 'Repairability'

iFixit Surface Pro Teardown Reveals Impressive Battery, Poor 'Repairability'

The teardown artists at iFixit discovered the "Cadillac of batteries" inside Microsoft's new Surface Pro but the inaccessibility of its parts led the site to give the tablet a 1 out of 10 score for repairability.

The Surface Pro became the first tablet ever to receive iFixit's lowest repairability score and joined last year's MacBook Pro with Retina Display from Apple.

According to iFixit there's the tar-like glue anchoring down the display assembly and it took over an hour to figure how to get inside.

Then there are about 90 screws holding stuff together inside the 10-inch Windows 8 tablet, plus more glue holding the battery to the case.

Microsoft sourced the Cadillac of batteries from LG: an Escalade 42Wh unit. The battery is rated for 7.4 V and 5676mAh.

The Surface Pro has an Intel processor and chipset, so that battery still only supplies about five hours of tablet life, according to iFixit. What's more interesting the Surface Pro's chip array requires a pair of small fans - unusual for a tablet of its size.

Also iFixit discovered under the hood of the Surface Pro:

  • Intel Mobile HM77 Express Chipset
  • Intel Core i5-3317U Processor
  • 8 x 512MB Micron 2LEI2 D9PXV 4 Gb RAM for a total of 4GB RAM
  • Marvell Avastar 88W8797 Wireless/Bluetooth/FM Radio Controller
  • 3 x Atmel MXT154E Touchscreen Controllers
  • 2 x Winbond 25X05CL Serial Flash
  • Winbond 25Q64FV Serial Flash
  • Integrated Technology Express IT8519G
  • Atmel UC256l3U 256KB Flash, 32-bit AVR Microcontroller
  • ON NCP6132A 3 Phase Controller
  • Atmel MXT1386E Touchscreen Controller

The teardown site singled out a few more components for closer examination, including the Wacom W9002 chip which enables the Surface Pro's Wacom pen input and the internal storage, a 64GB Micron RealSSD C400 with 500MB/s read speed and 95 MB/s write speed.
