From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello. I just want to ask, I already tried search many resources, but I still can't find a way to reduce battery drain while sleep on Ubuntu on Dell laptop.

I seen that it use S0ix, the new standard that many manufacturer use but when sleep it drains a lot battery, in just 6 hours the battery gone 0.

Any help is appreciated. This is company laptop and it requires me use ubuntu (I don't like it but I don't have options to changes OS/distro).

Thanks

Check with powertop that runtime power manage is enabled for devices (tunables are "Good").

It looks like it has a RTL8111H for Ethernet, which is known to be problematic with sleep. My machines don't go below C3 due runtime power management being disabled for Ethernet, but enabling it causes it to fail to come out of suspend correctly.
