Summary: System slows down when AC plugged in
Product: ACPI
Version: 2.5
Kernel Version: 3.8.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: acpi_ot...@kernel-bugs.osdl.org
ReportedBy: dennis.jan...@web.de
Regression: No
If I plug in my AC adapter, the system suddenly becomes a lot less responsive.
The issue disappears again when I remove the AC adapter.
Any hints on how to debug this?
The System is a Samsung NP535U3C-A04DE with AMI UEFI BIOS in CMS mode.
Also noteworthy: Acpi is a bit confused about what's going on and shows the
battery is discharging (but it isn't), while correctly stating the AC adapter
to be online:
acpi -V
Battery 0: Discharging, 98%, 11:09:10 remaining
Battery 0: design capacity 6100 mAh, last full capacity 6100 mAh = 100%
Adapter 0: on-line

Thermal 0: trip point 0 switches to mode critical at temperature 105.0 degrees

Cooling 0: LCD 0 of 50
Cooling 1: Processor 0 of 10
