Let me explain everything again, maybe my English is not so good. Statistics about power usage were generated when the laptop was on battery after a fifteen-minutes-long usage. (When connected to AC powertop says no acpi power usage estimate available). Statistics about battery, instead, were generated when connected to AC power but I can assure you that when on battery "remaining capacity" varies over time (always decreasing obviously :p ). I agree with you that ACPI is giving me misleading information: when I use ibam to estimate remaining battery capacity I obtain different percentages between (Bios, Battery percentage and Charge percentage).
