[olpc-help] Alternate external power adapters

[Robert Howard]

Richard,

Following your lead I just took a look at an ASUS EEE 1000HA  
laptop's  AC adaptor ( ASUS Model EXA0801XA ). The connector of the  
EXA0801XA fits the XO and has the correct polarity.

The EXA0801XA is rated at 12 Volts 3A max. output.

I plugged it into my XO and the XO power light turned on. No smoke ;)
