Notes
Tested with Ubuntu 13.04 32-bit Live DVD, used to recover data from a Windows 8 model U840/001 over a wireless network. Required to change to “legacy” boot mode in BIOs (Access by tapping F2 on boot) from full UEFI otherwise unit will continually refer to Windows install, even when selecting a boot device manually (Access by tapping F12 on boot).
Summary
The Ubuntu 13.04 32-bit Live DVD behaves acceptably, no application crashes and few anomalies, if any. Touchpad seemed appropriate speed and was comfortable to use as is. Was not particularly slow, despite being a live distro.
