Be aware: Jolicloud drains battery / power

Two days ago I wrote about how you can install Jolicloud in easypeasy to get the best of both worlds. While it might be fun to test Jolicloud, please be aware that Jolicloud is alpha software and consumes a lot of your battery.

Technical

The computer can use very little power when the CPU isn’t being awakened. This is because of what’s called a tickless kernel. The jolicloud-daemon however wakes the CPU all the time (more than anything else), which mean your computer won’t be able to save power.

Jolicloud consumes a lot of power / battery

I need my power – what do I do?

If you’ve tested Jolicloud, and want to remove it for the time being, do this:

1. Open up a Terminal (Accessories > Terminal)

2. Write “sudo apt-get remove jolicloud*” and press Enter

3. After you’ve typed you password, Jolicloud will be removed. Log out and back in and Jolicloud stops draining your battery

Jolicloud force cpu to 100% for performance. Change it “On demand” in cpu scaling applet and no battery drain anymore.
Noticed earlier today and since then my battery is back to normal. I’m testing again.
HTH.

could it be that jolicloud screws up your synaptics repository somehow? Since installing (+removing) it I have now got problems with Synaptics-Settings-Repositories.
When I now run:
gksu software-repositories-gtk I get the wonderful error “error: could not find a distribution template”. My system now seems to have forgotten it was easypeasy1.5 … and thinks it is vanilla ubuntu…

After removing jolicloud following your instructions in this post, the resulting interface is mixed. At the top of the screen, on the space between the panel and the icons, there’s a line with the jolicloud logo and the word “jolicloud”. How I can get back the original EP 1.5 interface (eeepc 1000h)

Your advice to stop the battry drain by Jolicloud is very dangerous. It eliminates the OS and makes the boot drive unbootable.
