Is this the USB to serial cable I need to reset the RTC? I saw such a cable mentioned in an old post on the Laptop forum. I have two older XOs and I cannot get either of them to boot up. The article I read on the fourm seemed like a possible solution.
Yes, this is the USB to serial cable that you would want to use to reset the RTC.
If you would like one, please send your name, shipping address & email along with a note stating you’d like the “OLPC Serial Adapter Kit” to : ilovemyxo [at] gmail [dot] com
Thank you very much. My XO is back! According to my Journal after 4 years and 8 months, magnificent.
Worked perfectly for resurrecting a pair of XO-1s who got stuffed in a box during a move and forgotten long enough that their RTC batteries had discharged. Loved the speedy shipping, and my compliments on your build quality – simple, nice, and clean.
