I tried all the above and now it won even flash orange
bad batteries can lock up the board. pull the battery, plug in the cord and power up.
if it starts, it's the battery. if it doesn't, the power supply or even the power supply
jack on the mother board could be at fault. if you are handy, set aside an afternoon
to pull the motherboard and re-solder or replace the power input jack. if you are not
handy, shoptime.
in any case double check your power supply and the input jack after bypassing
the battery.
