&lt;hr /&gt;
&lt;div&gt;Select ThinkPads feature switchable graphics, where a low power consumption integrated GPU and high performance dedicated GPU is combined and you have the ability to switch between them, sacrificing either performance or battery life.&lt;br /&gt;
&lt;br /&gt;
In Windows XP this switching requires a logout/login, while in Vista and Windows 7 there is support for runtime switching.&lt;br /&gt;
&lt;br /&gt;
Under Linux, the switching so far had to be done by entering BIOS setup and changing between &amp;quot;Internal&amp;quot; (low power, integrated), &amp;quot;External&amp;quot; (high performance, discrete) or &amp;quot;Switchable&amp;quot; (OS selectable) options.&lt;br /&gt;
&lt;br /&gt;
Depending on which Linux version you use, you could have the following effects&lt;br /&gt;
* On Ubuntu 8.10 (Intrepid) BIOS setting has to be either on Internal or External, not Switchable.&lt;br /&gt;
* On Ubuntu 9.10 (Karmic) the Integrated Intel card works with both Integrated or Switchable set&lt;br /&gt;
&lt;br /&gt;
Lenovo has published a [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70495 Switchable Graphics FAQ] you may want to review.&lt;br /&gt;
&lt;br /&gt;
== Switchable Graphics and Docks ==&lt;br /&gt;
&lt;br /&gt;
ThinkPads with switchable graphics can only drive DVI or DisplayPort outputs on Docks by using the high-performance discrete graphics card, the integrated GPU is just not attached to the DVI or DisplayPort outputs (though VGA output through the dock is possible).&lt;br /&gt;
&lt;br /&gt;
== Development status ==&lt;br /&gt;
David Arlie has been working on switching between GPUs without having to reboot, and changing BIOS settings. An initial version of a new driver (vga_switcheroo) has been merged in the 2.6.34 kernel. This driver allows switching between graphics cards, but requires that the Xserver is restarted. Full seamless runtime switching support will require significant Xserver work.&lt;br /&gt;
&lt;br /&gt;
http://www.phoronix.com/scan.php?page=news_item&amp;amp;px=ODAyMg&lt;br /&gt;
&lt;br /&gt;
A script to switch between ATI discrete graphics with the fglrx driver and Intel integrated graphics with xorg driver through rebooting and selection in the bios is posted here.  The user must reboot, but no further configuration is needed as the script detects the card used and copies the correct libraries and configuration file.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== ThinkPad models which may have this feature ==&lt;br /&gt;

* {{T400}}, {{T500}}, {{T510i}}, {{T420}}, {{T420s}}, {{T520}}&lt;br /&gt;

=== Power Adapter ===&lt;br /&gt;
&lt;br /&gt;
The W520 comes with a special [http://www-307.ibm.com/pc/support/site.wss/MIGR-76762.html 170W AC adapter (P/N 0A36227)] that is currently not shipped with any other Thinkpad. Note that it is different from the W700 [http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70684 170W AC adapter (P/N 41R4421)]. The W520 AC adapter is larger but lighter than the W510 135W AC adapter. &lt;br /&gt;
&lt;br /&gt;
Most newer (20V) Thinkpad AC adapters have a compatible plug with the W520, but not all of them will work due to power constraints. The following table shows which AC adapters can be used to run the W520:&lt;br /&gt;

&lt;br /&gt;
The 135W adapter is sufficient to run the W520 without throttling. The 65W and 90W adapters can only be used to charge the battery while the W520 is not running, that is, powered off, hibernated, or suspended.&lt;br /&gt;
