Now we hunt down how the events are generated by the DSDT and SSDT and check whether it is an ACPI firmware bug, or something we are not doing right, or an EC bug. If it is an EC bug or an ACPI firmware bug we cannot work around, we add an event filter. Otherwise, we can try to fix it in a better way. > > BTW: dmidecode output, please.

Ok. Let's do it this way, then: please do a full acpi and dmidecode dump of your current BIOS, gzip them (remove UUIDs/serial numbers) and send them to us. Then, update the BIOS and EC, and do the same. That will help me do a differential analysis if the update happens to fix the bug. After I get both dumps, I will try to find out what we're doing wrong, if anything, and come up with a solution. BTW, latest firmware for your box is version 1.46: 6MET86WW/6MHT45WW Changelog at: http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/6muj25uc.txt There are important fixes if you can read between the lines of Lenovo changelogs, but they are related to EC firmware bugs on the KBC emulation and battery control. You really ought to update, but the chances of it fixing the double-event-reporting issues are low. Those changelogs are very incomplete. As for requesting BIOS updates from users: on thinkpads, you _REALLY_ have to update the firmware, because that's exactly what >95% of the users will do (Windows ThinkVantage makes it _really_ easy and automatic). Obviously we _will_ try to work around any dangerous BIOS bugs regardless of them being fixed in a BIOS update, but there are very good reasons for the thinkpad driver to have a facilty to whitelist/blacklist firmwares and warn the users that they need to update. And I just found out that now the battery pack firmware can also be upgraded. Joy. I *REALLY* need to get myself a 510/520-series box: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS003186 "What is Battery Firmware Update Utility? This battery firmware update utility fixes an issue where some batteries indicate an incorrect full charge capacity value. Because of this error, the amount of energy available for use is artificially low, decreasing the amount of time the system can be used on battery. The fix is entirely contained in the battery firmware update; there is no need to replace any hardware for this problem. The battery firmware update requires that a supporting Power Management driver and BIOS are installed. Lenovo has bundled the necessary dependencies and the battery firmware update into a common package. During the update, the system may reboot, or be shut down." Oh dear... Well, let me warn everybody about this one. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
