With this a TS-I tip is usable with a small netbook 19 V / 30 W PSU with power limit set to 40 W (38.9 W is reported during the heating up stage). Without this the device just reboots on attempt to turn on the heater (unless the power limit is set to 10 or even 5 W). This code doesn't affect maximum power available and allows up to 73 W when a beefy 24 V / 96 W PSU is used. Should be useful for all models, not just TS100. The fixed comments are based on calculations, not measurements! Fixes #693.
