The XO-1, previously known as the $100 Laptop or Children's Machine, is an inexpensive laptop computer intended to be distributed to children in developing countries around the world,[1] to provide them with access to knowledge. The laptop is developed by the One Laptop per Child (OLPC) social welfare organization.


Intentionally omitted features


In keeping with its goals of robustness and low power consumption, the design of the laptop intentionally omits all motor-driven moving parts; it has no hard drive, no optical (CD/DVD) media, no floppy drives and no fans. An ATA interface is unnecessary due to the lack of hard drive. There is also no PC card slot, although an SD slot is available.

Printers, hard disks, CD drives, DVD drives, USB drives, and many other peripherals can be connected via the USB ports. Further expansion is available through an internal SD card slot.


A built-in hand-crank generator, making it self-powered equipment, was part of the original design, but Negroponte stated at a 2006 LinuxWorld talk that it was no longer integrated into the laptop itself, but optionally available as a hand- or foot-operated generator built into a separate power unit.[11 More Videos and related stuff here.. A brief view at the WIKIPEDIA page.. The Hardware Specificatiosns as of Nov2007 are: he hardware specifications as of November 2007 are:[9] Full resolution‎ (2,000 × 2,544 pixels, file size: 622 KB, MIME type: image/jpeg)

  • CPU: 433 MHz AMD Geode LX-700 at 0.8 Watts, with integrated graphics controller


  • 1200×900 7.5 inch diagonal LCD (200 dpi) that uses 0.1 to 1.0 Watts depending on mode. The two modes are:

    • Reflective (backlight off) monochrome mode for low-power use in sunlight. This mode provides very sharp images for high-quality text.

    • Backlit color mode, with an effective 800×600 resolution that is asymmetrically reduced in complicated ways. See below for details.



  • 256 MB of Dual (DDR266) 133 MHz DRAM (in 2006 the specification called for only 128 MB of RAM[10])

  • 1024 KB (1 MB) flash ROM with open-source Open Firmware

  • 1024 MB of SLC NAND flash memory (in 2006 the specifications called for only 512 MB of flash memory[11])

  • Internal SD card slot[12]

  • Wireless networking using an “Extended Range” 802.11b/g and 802.11s (mesh) Marvell 8388 wireless chip, chosen due to its ability to autonomously forward packets in the mesh even if the CPU is powered off. When connected in a mesh, it is run at a low bitrate (2 Mbit/s) to minimize power consumption. Despite the wireless chip's minimalism, it supports WPA.[13] An ARM processor is included.

  • Dual adjustable antennas for diversity reception.

  • Water-resistant membrane keyboard, customized to the locale in which it will be distributed.[14] The multiplication and division symbols are included.

  • Dual five-key cursor-control pads; four directional keys plus Enter

  • Touchpad for mouse control and handwriting input

  • Built-in color camera, to the right of the display, VGA resolution (640×480)

  • Built-in stereo speakers

  • Built-in microphone

  • Audio based on the AC97 codec, with jacks for external stereo speakers and microphones, Line-out, and Mic-in

  • 3 external USB 2.0 ports.


  • Power sources:

    • DC input, ±11–18 V, maximum 15W power draw

    • 5-cell rechargeable NiMH battery pack, 3000 mAh minimum 3050 mAh typical 80% usable, charge at 0…45°C

    • 2-cell rechargeable LiFePO4 battery pack, 2800 mAh minimum 2900 mAh typical 100% usable, charge at 0…60°C

    • 4-cell rechargeable LiFePO4 battery pack, 3100 mAh minimum 3150 mAh typical 100% usable, charge at -10…50°C

    • External manual power options include a pull-string generator designed by Potenco
