FWIW, the battery stats are about the only power mgmt stuff that worked at all under 2.4.23 - suspend was completely non-functional, but I suspect that was because this machine has a GeForce 5200 Go, and the closed-source nvidia drivers don't do ACPI... please try latest ACPI patch. it resolved some battery issues on dell laptops. if it's not lucky, please attach your DSDT. Please try an updated kernel, there was a regression in this area that was fixed recently. thanks, -Len closing due to inactivity. |
Description of problem: I dropped kernel 2.6.1-65 onto my Dell Inspiron 5150, and /proc/acpi/battery/BAT0 is not producing any useful information. Under 2.4.23 and 2.4.24 (from Planet CCRMA), I was getting useful battery stats. bonanza% cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: unknown present rate: 0 mW remaining capacity: 0 mWh present voltage: 0 mV bonanza% cat /proc/acpi/battery/BAT0/info present: yes design capacity: 0 mWh last full capacity: 0 mWh battery technology: non-rechargeable design voltage: 0 mV design capacity warning: 0 mWh design capacity low: 0 mWh capacity granularity 1: 0 mWh capacity granularity 2: 0 mWh model number: serial number: battery type: OEM info: bonanza% dmesg | grep -i acpi ACPI: RSDP (v000 DELL ) @ 0x000fdea0 ACPI: RSDT (v001 DELL CPi R 0x27d30b03 ASL 0x00000061) @ 0x1fff0000 ACPI: FADT (v001 DELL CPi R 0x27d30b03 ASL 0x00000061) @ 0x1fff0400 ACPI: MADT (v001 DELL CPi R 0x27d30b03 ASL 0x00000047) @ 0x1fff0c00 ACPI: BOOT (v001 DELL CPi R 0x27d30b03 ASL 0x00000061) @ 0x1fff07c0 ACPI: DSDT (v001 INT430 SYSFexxx 0x00001001 MSFT 0x0100000e) @ 0x00000000 ACPI: Subsystem revision 20040116 ACPI: IRQ9 SCI: Edge set to Level Trigger.
