I have received the brand new xo laptop ,but when I plugged in adaptor ,the charging light is orange,
when power on the button,the green power light turn on,but have no any signs of booting,it is black screen as I have not pressed the power button?
Do I have to fully charged before power it on?(But I think it can use ac adaptor directly ,isn't it ?)
Can some one help me,thanks,otherwise I have to sent it back to the seller if it cannot solved.

"green power on LED and no display" is my situation
the machine is from manufactuing date is 2007 ,I do not know where is come from,
possibly from Buy one give one.
no firmware can be update ,
I have followed the "no fail update" to try update the firmware but still fail in this bricked OLPC!
It cannot show any # message "Release the game key to continue" appears on the screen.
Because the display is still quiet ,no backlight either.
Have came across some fix clock topic,but after several hour of reading I still get no idea of what is a
OLPC Serial Adapter ,therefore is there other easier method to make it live again,I really love this machine but only have no chance to see it booting!
