In the early days of G1G1 many people expressed frustration with the odd combination of barrel/pin size used in the 12V Ext power adapter. The availability of this connector on the market is minimal. I'm happy to report that this will hopefully begin to change. Both the ASUS Eee (900A) and the ACER Aspire 0ne (AOA 150) external power adapters fit the XO and they both "Work For Me". The Aspire output voltage is 19V which is in the "might not work" zone for the the XO. The Max input voltage of the XO is 18V. Above 18V the protection circuitry can kick in. The exact voltage is dependent of on variance of the Zener diode in the protection circuit. You won't damage anything with higher voltages (until you get to say 30V or higher) but the internal DC/DC switcher won't turn on. I hope this info helps people looking for alternate adapters. -- Richard Smith <[email protected]> One Laptop Per Child _______________________________________________ support-gang mailing list [email protected] http://lists.laptop.org/listinfo/support-gang ------------------------------------------------------- -- Niklaus Giger _______________________________________________ OLPC-ch mailing list [email protected] http://lists.laptop.org/listinfo/olpc-ch http://wiki.laptop.org/go/OLPC_Switzerland
