Re: +5W power consumption when playing audio on X201 with Linux

I believe that "package" refers to the CPU package, i.e. the complete CPU (as opposed to the individual cores.) This would be useful since threads can (and will) shift around from core-to-core. [1] Well, that would include PCI Express, DMI and Memory Controller too, since those have been integrated...

Re: +5W power consumption when playing audio on X201 with Linux

Wait, so it's actually just +1W due to audio? Well... yeah, that seems pretty reasonable actually. My bet is that the audio player(s) that you're using are keeping the CPU out of the deeper C-states. Have you tried checking with powertop to see if that's the case? I know you said that they're not g...

Re: +5W power consumption when playing audio on X201 with Linux

I just tried Ubuntu 12.04 beta with XFCE. The problem still remains. With everything turned off I can get power consumption as low as 7.5W but as soon as I play any music it raises to 13.2W. It seems to be somehow CPU/RAM-related. If I stress the CPU with mprime’s Blend-test the power consumption go...

Re: Keyboard illumination light problem

FYI, the LED is attached to the LCD cable and I suspect that picking up the laptop by the screen could have something to do with it as it prolly caused pressure on the cable which led it to break eventually. I do that very often with my X201 and my ThinkLight™ failed after ½ year or so. So it might...

Re: Fan ticking/clicking noise

I can confirm this problem. Since the X220 belongs to my sister I couldn’t do much testing yet. The only time where I was able to hear it was after waking up from suspend to disk while disconnected from AC Power.

I didn’t even know that there is allready a setting for Hibernate/Suspend shortcuts. Thus I created my own Global Shortcut (Command/URL) which runs the following command:

Re: Thinkpad X120e and Linux

I got Fedora 15 to run and work with wifi + bluetooth, I just didn't like how "simple" the new GNOME shell is. You don’t have to use Gnome on Fedora. You can use what ever you like, be it XFCE, KDE, Fluxbox/Openbox etc. In my opinion there is not much difference between the „big“ Distros like Ubunt...

Re: Audio ACPI interface is read-only; can't unmute

http://www.thinkwiki.org/wiki/Thinkpad-acpi says: As of kernel 2.6.33 the thinkpad_acpi driver now has a ALSA sub-driver which creates an additional ALSA volume control which represents the volume and mute buttons on the ThinkPad keyboard. Unfortunately no further integration exists at this point wi...

Re: will adding 4GB increase bat. consumption but improve gfx?

But faster RAM or two RAM-modules instead of one (singlechannel → dualchannel) could improve graphics performance.

Re: X220 128 SSD Enough?

The 64bit version of Win7 requires 20GB of disk space according to MS. So how bad can it get? I very much doubt that some Lenovo tools and drivers will require more than 500MB of space – the rest depends on what software you want to install. But unless you want to install some modern games which can...

+5W power consumption when playing audio on X201 with Linux

Hi folks! My Thinkpad X201’s power consumption raises from ~12W to ~17W when playing any kind of audio. It seems that the additional power consumption is not caused by interrupts or CPU usage of alsa or pulseaudio. The problem does not occur on Windows XP where the consumption only increases slightl...
