Suggestions / Conformity marking
« on: October 29, 2015, 02:45:13 PM »
Hi all,

In order to produce and distribute PowerPC notebook in various countries, conformity declaration must applied:
Has anyone considered to perform conformity tests in a thirdy part laboratory (very expensive, more than 20k euro), or do we simply apply the self certification?
Honestly speaking, I don't know if a notebook can be self-certified; if anyone has access to marking requirements, please add the necessary informations.


Suggestions / Battery

Hi all,

Looking for some technical specifications about battery in the forum, I didn't find anything, so I have some questions and suggestions regarding it.
  • Has anyone evaluated the total amount of current, in order to define battery requirements?
  • In a "Open Hardware" obviously we cannot mount a proprietary cell pack (ex: an HP laptop battery pack), but it's necessary to design a specific one. Some considerations, based on my job experience:
    • A custom solution is unfortunately a very expensive solution (I think total cost could be more than 100 euro)
    • For small productions like this project, manufacturers could change package dimensions or close production without any notice.

    My suggestion is to find possibly more than one manufacturer and a package as common as possible, in order to fit different products in the same area reserved in the chassis.
    Has anyone already looked for battery solutions?
