150 Watt power inverter

You would be much better off using a 12v to multiple voltage output supplies adaptor. I use one with my Thinkpad and its much more effecient. Leave the inverter for charging phones etc.

Michael, those figures on the laptop I would think are for the DC side of the circuit. What figures are written on the bottom of the power pack for the notebook or does the G40 have an inbuilt power supply?

You might find that the power pack for the note book draws a bit more than 150W at start up. Closer to 200W

cheers,
Sam.

I think you should buy a Waeco....

My Thinkpad 600 runs OK off a 300 MSW Inverter, but I rarely use it for this.
The Kerio Adaptor is much more compact and is the Duck's Guts in my opinion.

Having been in the computer industry all my life the last thing I want to take away bush or camping is a laptop. They are exactly why I need a holiday..! LOL

Inverters are an inneficient way to recharge a laptop, if you can, buy a 2nd or even a 3rd spare battery if you need it, leave the inverter or the power that runs it etc for something else.

I also have a G40. I used to run it off a 150W MSW inverter which used to cope when the battery was fully charged but wouldn't run if it was trying to run the laptop and charge the battery at the same time. I now use a 300W PSW inverter and have no problems.

The thinkpads have a much higher power draw than your average laptop (I had to replace the power supply and none of the generics would go near the required amps)
