That depends, if the board was damaged by improper connections (to eeprom) or is just "frozen"

Remove the main batteries and the 3V cell, remove any mPCI cards modem or wireless, plug in the AC and try to power it on. If this works, put everything back and that't it.

If not, then check if eeprom has 3.3V on it, if yes, check whether SCL and SDA are shorted each other or any soldering bridges or else.
