Hello, I am affected by this bug since, a couple of years (same laptop here, 530U). I have personally experienced it on my laptop on multiple Linux distributions (including Debian and Arch).
I perfectly understand your policies, but I do not really see the rationale behind closing the bug with WONTFIX and asking a lot of people to open a lot of new bugs to signal the very same thing. For me, the bug is indeed solved by the juanmanuel's userspace program (thanks a lot!!!!!!!!!) I've been running that program since it was posted on this thread, and it works like a charm. The bug is also clearly described upstream on the kernel Bugzilla, where juanmanuel's solution is being turned into a kernel patch, so an upstream fix is likely to be on the way. I hope you'll find a way to put in evidence the relevant information, especially when there will be 100 opened issues for this SINGLE problem (or 100 issues immediately closed as duplicates???): this is clearly a SINGLE bug with a SINGLE reference to a SINGLE upstream issue. >From my side, I am *not* going to open another bug just to increase the Internet entropy (and reduce the likelihood for someone searching about the problem to find the workaround)... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/971061 Title: acpi reports battery state incorrectly Status in “linux” package in Ubuntu: Won't Fix Bug description: I have a new Samsung 9-series laptop (NP900X3B) and the battery state is detected incorrectly. Basically the state what was at the time of boot stays active all the time - regardless of the ac-adapter state. Here is output from "acpitool -a -b" in various situations: When booted with charger connected and charger is still connected: Battery #1 : charging, 47.00%, 01:00:43 AC adapter : on-line When booted with charger connected and charger is now disconnected: Battery #1 : charging, 47.00%, 01:36:59 AC adapter : off-line [The battery couldn't possibly be charging when the AC adapter is offline!] When booted with charger disconnected and charger is still disconnected: Battery #1 : discharging, 47.00%, 01:39:44 AC adapter : off-line When booted with charger disconnected and charger is now connected: Battery #1 : discharging, 47.00%, 00:53:43 AC adapter : on-line [The battery is actually charging as the AC adapter is online] The percentage and time are correctly updated when the battery is actually charging or discharging - regardless of the reported state. So the state is the only thing that is incorrect. However a number of applications make their decisions based on this state (battery monitor, jupiter, etc.) and therefore behave incorrectly. "lshal -m" doesn't report anything when I plug the charger in or out.
