The OLPC XO Wiki has a questions and answers page. Today I took look at the hardware page and found a few important bits:
- JFFS2 compresses your data, performs wear leveling, and manages bad blocks so you don’t need to worry about the fact you are writing to flash.
- USB “thumbdrives” should be formatted to FAT32.
- Although the CPU supports sleep mode, and the hardware detects the the lid closing, the XO will not automatically enter sleep mode on lid closing until some time next year.
- The XO can remain plugged in constantly; the battery will not get overcharged.
