Hi, my Toshiba L645-S4060 also has this. bios version 1.70 Using ubuntu 11.04 battery shows as not present, and ac-adapter plugged/unplugged never changes in /proc/acpi/ My DSDT looks similar to Otto's I changed my DSDT and compiled it into a custom kernel. Originally ther was this line under the EC0 device: OperationRegion (EMEM, SystemMemory, 0xFF808001, 0xFF) I changed it to this: OperationRegion (EMEM, EmbeddedControl, 0x00, 0xFF) now battery status and ac adapter status seem to work perfectly. -Steve Created attachment 58212 [details]
