The AC compressor is belt driven. There is an electric clutch that engages the belt drive to the compressor. The circuit for the clutch is driven by the Powertrain Control Module (PCM), which might feed to a relay used to drive the clutch. The PCM receives a start signal from the dashboard control knob or switch. There may also be a refrigerant pressure sensor that can moderate the output of the PCM to the AC clutch signal.

Is it normal for the bat to run down on a laptop when on ac power?
No. check that the AC Power lead is plugged in and turned on. if the AC power lead is plugged in and turned on and still the battery is discharging, check that the AC power lead is working. this can be done with a multimeter. if the lead is faulty, replacements can be found. check the input power required by the laptop, as too much will blow the laptop up, and not enough will still make it discharge.

What would cause AC low pressure line to be to high?
If you check the pressure on the low pressure line and it is very high then you should make sure the compressor is ON. You may have put the blower on, but on the dashboard there usually is a button that turns on the ac compressor. When the comp is on the pressure will drop into the "blue" range. This is the first check, and the simplest
