I just bought the m15 and I'm already having doubts. Can anyone help?
I sometimes spend long periods off-grid, and use one of those readily available DC-DC converters to power my past (mostly Asus) laptops from a 12 volts DC supply. It's always worked great, once you find a converter with a plug/tip that matches the DC plug that connects to the laptop's power socket. (Usually DC-DC converters come with a selection of tips to match the plugs of a variety of laptop manufacturers.)
So I'm now looking for a similar solution for my new m15, but there are a couple of snags:
1. The included m15 AC power supply is rated at 9.23 amps DC output which is quite a bit more than my past laptops, and more than the max output current of all of the DC-DC converters I can find. I don't think this will be a problem as I will probably just be using it to charge the m15 or using it for very light work, so I guess the current draw will be fairly low.
2. Does anyone know if the m15 DC power plug/tip is a standard Dell type? It is quite a bit bigger than my existing laptops, so I'm worried that it might be a new plug specifically for the m15 that I will not be able to find a match for in any DC-DC converter.
3. I've found mention that some/all Dell laptops have some sort of digital interface in their AC power supplies, so the laptop will refuse to work with non-Dell power supplies. This would obviously prevent me from using a DC-DC converter, Does anyone know if the m15 has this abomination, or should I be OK to use a "generic" power supply with it ?
Thanks for any helpful comments.
