Comment 14 for bug 1088146

I am running the same bios (.216) with an n56vz-p4364 laptop.
I have the same battery red blinking problem, the fans goes to max, and I never tried the usb connection power charging.
But adding acpi_osi=Linux doesn't resolve anything, I resolve powering off, removing and re-adding battery.
But some after time the problem come back again.
I have dual boot, and I have the same problem on my winzoz 7 pro x64 (downgraded), as my ubuntu 12.10 amd64, so I think is a bios problem.
In this moment I have ac connected, but the battery isn't charging, 5% always...
