Distribution: debian unstable Hardware Environment: Raon Digital Everun (AMD Geode UMPC) Software Environment: Problem Description: Smart Battery not recognized by driver, even though i2c tools show it to be there Sensors-detect detects a Smart Battery, and i2cdetect shows why: # i2cdetect -y 0 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 0b -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- UU -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- I believe that the device at 0x0b is a smart battery because (1) the manufacturer told me the device had a smart battery on SMBus, (2) I can dump its contents and watch values within the register change in ways that make it really look like a battery. In particular, the stuff at 0x0c-0c0f looks like battery voltage or charge level (not sure of the scale)... it goes up when AC plugged in, down when discharging the battery. 0x2f looks like it represents the AC adapter state somehow; it takes different values when the AC is plugged in or not. # i2cdump -y 0 0x0b 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: 00 e6 0a 01 00 ff ff 01 fd 5b 04 04 02 62 44 18 .???...??[???bD? 10: 40 ff ff 58 00 38 a7 1b fc 5c 31 fb 08 XX XX XX @..X.8???\1??XXX 20: 0b 07 04 0d XX XX XX XX XX XX XX XX XX XX XX b0 ????XXXXXXXXXXX? 30: XX XX XX XX XX XX XX XX XX XX XX XX 00 1d 22 1d XXXXXXXXXXXX.?"? 40: XX XX XX XX XX de XX XX XX XX XX XX XX XX XX XX XXXXX?XXXXXXXXXX 50: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 60: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 70: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 80: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX 90: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX a0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX b0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX c0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX d0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX e0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX f0: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX XXXXXXXXXXXXXXXX However, I can load the sbs and sbshc drivers and nothing happens (no battery information in /sys/ or /proc/ ACPI trees, only an AC adapter which claims to be always on, which is what my DSDT tells ACPI to say... see http://bugzilla.kernel.org/show_bug.cgi?id=9137) Any help appreciated!
