Summary: No battery status information on HP EliteBook 2730p Product: ACPI Version: 2.5 KernelVersion: 2.6.27.4 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Power-Battery AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Latest working kernel version: N/A Earliest failing kernel version: 2.6.27.4 Distribution: Debian Lenny (testing) Hardware Environment: HP 2730p tablet PC laptop, Core2 Duo CPU L9400 @1.86GHz, 4GB RAM Software Environment: Fresh install of Debian Lenny/testing with vanilla 2.6.27.4 kernel from www.kernel.org The only change made is the intel_agp patch from http://intellinuxgraphics.org/download.html (the system hangs up otherwise). Problem Description: ACPI doesn't provide battery status. In fact, the directory /proc/acpi/battery is missing completely. dmesg shows multiple ACPI errors during the boot time of the type ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.BAT0._BIF] (Node f7446ba8), AE_TIME All kernels prior to 2.6.27 that I've tried boot with apci=off option only (with only one core recognized), so I don't know whether this problem existed in earlier versions. I found several bug reports about similar problems on other types of laptops, but they all were supposed to be fixed in 2.6.27 by now. By the way, temperature sensors at several zones and frequency scaling work. Steps to reproduce: Boot the laptop. I'm going to attach the outputs of dmesg, lcpci, and acpidump to this bug report for more details. I'm not sure which other information might be useful.
