Update 2015-03-15: As Antiplex mentioned in the comments, the resources are slighlty out of date. An update is pending I use my laptop (Lenovo Z370, with Ubuntu 11.10) a lot in the college. Unfortunatly there aren’t enough plugs in the wall for all students and I’m not willing to bring a plug board with me every time. So my approach to the problem was to improve the energy consumption of my laptop.

Two days ago I’ve updated Ubuntu to 11.10 and it worked well. I started from scratch, so I won’t have to deal with “old” problems: Here is my setup: Plain vanilla Lenovo Z370 Harddrive was replaced by a 60 Gb Sata2 SSD Ubuntu 11.10 (Desktop edition) I installed the IdeaPad Driver Package (get it here) to get rid of a lot of the “Keycode 240” On the pro side:

New task of the day: Get my sd-card reader in my laptop working. My Lenovo IdeaPad is nice and everything but sometimes there are some annoying things. Like a not working sd-card reader. There absolut no reaction on Ubuntu if I insert a sd-card… Maybe, I will find out :-) Update: rmmod ehci_hcd doesn’t work echo "usb-storage" >> /etc/modules; modprobe usb-storage was promising, but doesn’t work either What do I know?
