sounds like the hamster needs to run faster.... or else chuck some more coal in the back...
Sorry ES, aint got a scooby.... but hopefully someone will... in the meantime.. i hope the above'll do..
That's a difficult one to diagnose, especially from long distance.
approaching things logically, if the same problem is occuring with both the in-car charger and the PSU/inverter combination then I think you can rule out either of those being the problem. It could be the truck's dropper (I'm no expert on vehicle electrical systems, unfortunately), but since your old laptop worked fine it's unlikely (though it could just be that the new laptop is a bit more particular about the quality of it's power supply). I take it it charges up fine using it's PSU plugged into 220V AC (a normal wall socket)?
That leaves the new laptop, and in particular the power management programs within the operating system (what is it incidentally, Windoze, Mac, or a proper OS like Linux?) Actually isolating a problem in here without access to your set up is nigh on impossible, though if you're using Windows you could fiddle around with the power management utility in the control panel and see if anything in there makes a difference.
Anyway, good luck, it sounds like you might need a bit.
I am no guru either but logically it sounds like a problem between the truck and the PC charger. Maybe the charger does not recognise the truck output?

Have you tried it when the trucks engine is running? The power supply may not be as stable or the truck might notice the large drain and cut it off to save the batteries on the truck?
I've bought the ACanywhere 300watt version for my laptop as I'm also a trucker but yet to try it. I'll give mine a go and see what happens.
Hope it fixes itself soon! Failing that, have a word with one of the fitters in the yard they may know more on how the truck is wired.

sounds like both the charger and/or the inverter require more current than the 12v dropper can supply, most 12v droppers are limited to only a few amps.
Have had this problem when setting up radio's on trucks for charity convoys.
either that or the voltage regulator in the dropper is bolloxed have you shorted out the 12v socket by mistake at any time.
Only other suggestion is bit of cable, two croc clips and take a supply across 1 of the batteries, but make sure it's only 1 or your get 24 volts. this will only work on a temp basis, as after a while you will affect the charging of the truck batteries.
your new laptop is actually really good on power consumption, but yep compared to the old one it probably does draw more current. you should be ok with a 600w inverter. my question is what ampage is it? i think you are going to need at least 5amps.
good luck

yay another truck driver...
ok..its doubtful the droppers to blame
its more likely to be some power cutoff protection in your mains adaptor/charger.
you may as posted already have to get a plug in which converts the ampage to what it needs to be either boost or regulate. thing is i dont think its gonna get done tonight as it would take a technician to diagnose it safely without the risk of popping your new laptop..
some older droppers can surge slightly affecting voltage annd amp output. this is only minute but maybe your laptop is sensetive to this...
after all that i would say its a safety problem and your laptop is telling the power source to bog off...a lot like my x incidently
hope its sorted sonn
goodluck
