We at OLPC News want you to buy an XO laptop - the famed "$100 laptop" even if its not $100 dollars. Its an amazing tool to learn learning, educating children and adults in the process. But buying an XO laptop can be a challenge - they're not for sale at the local Best Buy. So we've made this handy F.A.Q. for you: Where can I buy an XO-1? OLPC only sells XO laptops in large volumes (thousands of laptops) to governments. If you'd like to purchase one, the best option is via eBay XO sales. How much does the XO-1 cost? Since the XO-1 is not available for commercial sale, this question is difficult to answer. It costs OLPC just under $200 to make and deliver them in large numbers. If you're looking to purchase one, they cost whatever the eBay XO market will bear. Why can't I buy a few XO's from OLPC? OLPC has at times allowed small-lot purchases and at other times has not; the logistics of supporting such sales are complex. At the present time, OLPC is adamant that they will not sell XO laptops to individuals or in small numbers.

Where can I get an XO-1.5? OLPC is releasing a new laptop, the XO-1.5, but you can only get one through the Contributors Program application process. You'll need to demonstrate that your project will give back to the community. When can I buy a XO 1.5 motherboard upgrade? Cross your fingers and hope that OLPC starts to value the G1G1 community; if so they may offer the motherboard so we can upgrade XO-1's with the XO-1.5 motherboard. But so far, nothing.Get OLPC News daily - enter your email address:The XO-4 Touch laptop is the latest refresh of the XO laptop. It is available in two models: XO-4 and XO-4 Touch, with the latter providing multi-touch input on the display. Like the XO-1.75, it uses an ARM processor to provide high performance with low power consumption, while keeping the industrial design and batteries of the XO-1. XO-4 laptops ship with OLPC OS 13.2.7 based on Fedora 18, including both Sugar and GNOME software. An Android build can be used by deployments but is not offered from factory.

The XO-4 laptops are identified by set of four dots in a diamond on both sides of the hinge cover.

XO-4 is designed around the Marvell PXA2128 system on a chip. The XO-4 Touch has the ability to sense and track two simultaneous touches of the display. In order to provide this functionality without degrading the performance of the display in direct sunlight, an infrared touchscreen technology from Neonode is used.

This technology is also capable of sensing and tracking any stylus with a diameter larger than 8mm. To avoid damaging the surface of the display, it is recommended that any stylus have a relatively soft tip. See also touchscreen troubleshooting. The screen can pivot and folded backwards so the XO-4 Touch becomes a tablet or eBook reader. Several buttons on the frame offer different modes of paging, scrolling, etc. See Laptop Batteries or more information. On XO-4, there are two different firmwares installed: The bootloader run by the CForth interpreter on the security processor is responsible for initializing the SoC pins and the main memory. It then loads Open Firmware into main memory and starts it executing on the main processor. This CForth bootloader then continues to execute on the security processor, processing input from the keyboard and touchpad. Open Firmware (OFW) initializes the system peripherals, then loads the OS kernel into memory and starts executing it.

OFW also includes hardware diagnostics. There are four distinct pieces of software on the XO-4: All the firmware images are included in the operating system builds, so usually just installing a new OS and rebooting (with a charged battery, and external power connected) is enough to upgrade everything. There are some exceptions that apply to pre-production units (in the hands of developers and testers): A-test units (very early prototypes) are no longer supported - don't bother trying to upgrade them. Upgrading from Open Firmware Q7B01 If you are running firmware Q7B01, the system will not boot (you just get the 'ok' prompt), and automatic firmware upgrade will not happen. You must upgrade manually to e.g. q7b02, using the instructions below. XO-4 firmware Q7B11 breaks automatic upgrade for touchscreen firmware versions before 0.0.0.10 on C1 models. After reflashing to Q7B11 (or later) from an earlier version, you must (just this once) manually upgrade with

Otherwise the touchscreen will not work. More info can be found at XO_4_Touch_Testing#Reprogramming_the_Neonode_Firmware. This does not apply to B1 units, where the touchscreen will continue to work over this upgrade, intentionally locked to an old touchscreen firmware version. Refusal to update EC code When upgrading from old software versions, Open Firmware may refuse to update the EC firmware, showing a battery icon with a bad face on every boot, and logging the following messages over serial and during verbose boot: This is due to a change in how OFW gets battery status. To solve this, with a charged battery and external power connected, run at the ok prompt: Place a recent release of the Q7BYY firmware onto an SD device, and place it in the external SD slot, or on a USB drive. Interrupt the Open Firmware (OFW) boot process by pressing the ESC key. Or for a USB drive: The laptop will automatically reboot. If you need to do this to a bare motherboard, you can use the flash!
