>Description:
I'm using Acer aspire 5536 notebook. I have several ACPI related issues:
- hotkeys not working (volume +/-, screen brightness +/-, Wi-Fi on/off, sleep button).
- I'm unabled to use S3 power saving mode. If I do S3 without hw.acpi.reset_video then computer wakes up but screen is black - backlight is off.
- I'm unabled to use S3 power saving mode. If I do S3 with hw.acpi.reset_video=1 then computer wakes up, backlight is on but console no do not works (no output to monitor).
- Battery status showing "Remaining time: unknown".
