Hi Shem,

I tried tp_smapi-0.07 it on my R51 1836-GEU.

tp_smapi: tp_smapi 0.07 loading.
tp_smapi: initialized, smapi_port=0xb2.
tp_smapi: driver successfully loaded.

Unfortunately I cannot check if all this functionality works
in Windows for now, as I don't have it installed.

Thanks for your great work, I am happy to be able to inhibit
battery charging, which means that I don't have to take out
the battery anymore (I rarely use it but like to have it in
the laptop:)).

Regards,
George
