Hi,
I'm just reporting what powertop says. It says:
Code:
The battery reports a discharge rate of 21.6 W
The estimated remaining time is 169 minutes
Summary: 264.4 wakeups/second, 0.0 GPU ops/second and 0.0 VFS ops/sec
Power est. Usage Events/s Category Description
17.7 W 0.0 pkts/s Device Network interface: eth0 (e1000e)
4.13 W 100.0% Device USB device: usb-device-04d9-1133
2.10 W 73.3% Device Display backlight
100 mW 100.0% Device Audio codec hwC0D0: IDT

0 mW 24.1 ms/s 25.5 Process /usr/bin/gnome-shell
0 mW 12.3 ms/s 1.0 Process powertop
acpi -V gives:
Code:
Battery 0: Discharging, 83%, 02:28:13 remaining
Battery 0: design capacity 7650 mAh, last full capacity 6011 mAh = 78%
Adapter 0: off-line
Thermal 0: ok, 47.5 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 107.0 degrees C
Cooling 0: LCD 4 of 15
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10
It is much hotter than it used to be - resting my hands on it is uncomfortable, and working with it on my lap basically impossible for more than a minute or so. It USED to be the coolest laptop I had ever used (has an SSD etc). (Its a Dell latitude E6500)
So there may be a bug with acpi or powertop, but *something* is still making it run hot, and it isn't the processors.
Cheers

Hi again,
Disabling the NIC in BIOS was a great idea. The laptop is running significantly cooler.
This is what powertop now says:
Code:
The battery reports a discharge rate of 16.4 W
The estimated remaining time is 200 minutes
Summary: 279.1 wakeups/second, 0.0 GPU ops/second and 0.0 VFS ops/sec

Still not sure what caused it...
Thanks

Since this is reproducible (re-enabling NIC in BIOS reliably causes overheating), I could report as a bug. But:
1) on what component? kernel?
2) any suggestions for what useful information I would need to attach?
cheers
