Suspend to ram is very sustainable with mine. I haven't monitored it
precisely but it sure lasts longer than a night when starting with half a
battery (I have the 9 cells battery, by the way).

Hello,<br>
<br>
I should&#39;ve asked, how long does suspend go on a full battery for you?<=
br>
<br>
Leaving the laptop suspended with 50% battery exhausted the battery<br>
during the night. =A0I guess some device is not being deactivated. =A0I<br>
researched and it appears gnome is doing &quot;suspend to ram&quot; or S3 i=
n<br>
<a href=3D"http://www.kernel.org/doc/Documentation/power/states.txt" target=
=3D"_blank">http://www.kernel.org/doc/Documentation/power/states.txt</a>, s=
o only the<br>
RAM should be using the battery.<br>
<br>
Actually hibernate (or &quot;suspend to disk&quot;) is working with this la=
test<br>
stable kernel. No testing is needed for battery, the computer is shut<br>
down.<br>
<br>
For people with problems: I found the reading of &lt;kernel<br>
root&gt;/Documentation/power/* priceless, while knowing that to gnome:<br>
suspend=3D invoking S3, hibernate=3DS4.<br>
<br>
