Works fine. With there being no internal CD-ROM, I booted from a USB external drive. Just push the “Access IBM” button to boot from USB to live Ubuntu and then install.

Comes up as a SCSI device.

UK keyboard, trackpoint (joystick) and mouse buttons.

Fine. Ubuntu 7.04 very good for roaming and intermittent connectivity. The ((A)) wireless indicator does not come on.



Fine. Tested with pen drives and optical wheel mouse.



Fine. Also the keyboard sound off and volume controls drive the Linux master volume.

Detailed specification:

Lenovo Linux support:

This is a nice, light, robust, cheap, second hand laptop. It seems to be very well built, including the cool power supply. The only real issue is the lack of hibernate/suspend. I have used Ubuntu for over a year and now have it on all three of my machines. After eight years of Linux and a number of other distributions, I have no plans to change. With Ubuntu, desktop Linux has come of age.
