Huge power savings are harvested in this way (e.g. The XO is usable while the CPU and much of the motherboard is regularly turned off (and on) so quickly that it's imperceptible to the user. This Liquid-crystal display is the basis of our extremely low power architecture.The DCON also formats data for the display. The display-controller chip (DCON) with memory that enables the display to remain live with the processor suspended.(1) Grayscale (B&W) reflective mode: for outdoor use-sunlight-readable primarily lit from the front by ambient light high-resolution (200 DPI), 1200(H) × 900(V) grayscale pixels power consumption 0.1–0.2Watts (2) Color, backlight mode: for indoor use primarily lit from behind by the LED backlight built in sub-pixel sampling of the displayed color information results in a perceived resolution of at least 1024(H) × 768(V) power consumption 0.2–1.0Watts Two "modes" depending on lighting conditions:.Liquid-crystal display: 7.5” dual-mode TFT display.CAFE ASIC (camera- and flash-enabler chip provides high-performance camera, NAND FLASH and SD interfaces) Marvell 88ALP01: CAFE Specification or local copy plus presence detect erratum.Mass storage: 1024 MiB SLC NAND flash (a few "Red XOs" have been built with 2048 MiB of flash).Open Firmware used to load the operating system.DRAM memory: 256 MiB dynamic RAM data rate: dual-DDR333-166Mhz.Embedded controller: ENE KB3700 or ENE KB3700B.Graphics controller: Integrated with CPU unified memory architecture.North Bridge: PCI and Memory Interface integrated with Geode CPU ( info).Companion chips: PCI and memory interface integrated with CPU.i586 instruction set (including MMX and 3DNow! Enhanced) with additional Geode-specific instructions.CPU: x86-compatible processor with 64KB each L1 I and D cache at least 128KB L2 cache.A photo of the XO-1 motherboard is available, with or without annotations.Configuration: Convertible laptop with pivoting, reversible display dirt- and moisture-resistant system enclosure no fan.XO laptop with NiMH battery: 1.58KG (~3.48lbs).XO laptop with LiFePO4 battery: 1.45KG (~3.20lbs).Approximate dimensions: 242mm × 228mm × 32mm (see drawing to the right for detailed dimensions).The specification for the earlier CL1 version (with the wide dual-mode touchpad) is here. Note: this is the specification of the CL1A XO-1 production laptop. This page attempts to accurately reflect that information. The definitive laptop specification is only available in PDF format.
