This will probably not help you, but at Wikipedia you can read more about these interfaces: http://en.wikipedia.org/wiki/I2c http://en.wikipedia.org/wiki/Acpi http://en.wikipedia.org/wiki/Secure_Digital#SDIO I have recently been given a couple of Palm devices that I have barely started to play with, and they use the SDIO interface for things like WiFi. These need special drivers, so even if the WiFi chip (for example) in your tablet is supported by the Linux kernel it would probably not be trivial to get it to work if it is connected through an SDIO interface. AFAICT, I'm no developer. :) All I know about ACPI is that it is used for power management in PC's. There are Linux tools to Do Things (tm) - like acpitool to get or set ACPI values, and you can also look at /proc/acpi. The above pages will tell you more, though, and there are tons of information online if you really want to dig into it, but if you, like me, are not a programmer, it may be limited what you can actually achieve with it. I wish you the best of luck, though :) Petter -- I'm ionized Are you sure? I'm positive. pgpSFkZaVGvV6.pgp Description: OpenPGP digital signature

If someone has experience with that kind of technology, I would appreciate a little help. In the meantime, I have written a web page to summarize what I could get working: http://nsup.org/~george/comp/linux_lenovo_miix3/ I hope some of these frowny faces can become smily and that it may help people later.

Regards, My significant other has been looking wistfully at those devices, but she really doesn't want to use MS Windows with it. I'm going to go over that page and the links you mentioned this weekend. In the (probably unlikely) event that I find a way to contribute, I'll do so. I appreciate your efforts and your consideration in making the details available to the community.
