Be extremely careful. The inverter output is extremely high voltage and
can seriously injure or kill you. It's typically in the range of 800 to
1,600 volts, up around 10 - 20 KHz, current availability is in the range
of 5 ma to 20 ma. There is quite a bit of variability depending on the
exact machine and configuration.
This is no part of a laptop for an amateur to be fooling around with,
again, the voltages in the inverter can be very dangerous.
