Hardware modification
This page contains information about modifications to the XO hardware. These either fix a problem/shortcoming with particular implementations (or "builds") of the laptop, or extend its capabilities in particular ways. This page welcomes contributions from the community at large.
While some of these modifications are provided by OLPC, their use is not endorsed by OLPC. They are provided in the spirit of exploring the laptop hardware. Please remember that trying them is likely to damage your laptop.
Modification to XO-1 Production Models
These are modifications which may be made to the XO-1 laptop:
- Overclocking the XO-1
- Improving D-Pad (Directional Arrow Pad) control - The tooling for the D-Pad was changed on the XO-1.5 to incorporate this change!
- Drive XO1/ Charge Batteries by Bicycle
- Increasing the maximum USB power
- Adding a Bluetooth transceiver - a Bluetooth capable wireless module was added to the XO-4,
- Installing a different keyboard: part I: physical, part II: electrical, the keyboard used
- Increasing the SDRAM memory
- Neatly mounting a serial diag connector
- Adding a Touchscreen
And, not really a modification of the laptop, but possibly useful nonetheless:
Modification of Pre-production XO-1 Models
There were several thousand B4 version ("build") laptops built and distributed to developers and trials around the world. These machines (and their close cousins, the B3 and C1 builds distributed only to developers) are functionally equivalent to the production machines...except for a few minor tweaks which can make a huge difference.
- Modifying a B4/C1 to improve the suspend/resume performance
Even Earlier XO-1 Models
- The B2 build can easily be modified to support suspend/resume
Modification to XO-1.5 Production Models
These are modifications which may be made to the XO-1.5 laptop:
Modifications to pre-production hardware
These are generally already present in production hardware.
