What works out of the box

  • Gigabit ethernet adapter
  • Wireless
  • Graphics adapter and 3D accelerator
  • Sound
  • USB
  • Firewire
  • Hard disk laptop-mode
  • LCD brightness auto-adjusts depending on AC or battery operation
  • Fn buttons do generate ACPI events (/var/log/acpid)
  • Volume control, keyboard light and screen brightness control
  • Lid switch (LCD off when lid closed)
  • CPU frequency scaling
  • Suspend to disk (hibernate)

What does not work

  • Suspend to RAM (suspends sucessfully, but sometimes will not resume)

Not tested

  • SD card reader
  • PCMCIA slots
  • Embeded Security Subsystem (TCPA)
  • Active Protection System (HDAPS)
  • Modem

Notes

IBM Rescue and Recovery disks (seven CDs) can be created using preinstalled Windows: All programs→ThinkVantage→Create Recovery Media. However, as long as recovery partition (called predesktop in BIOS) is left intact, system can be restored to factory default without having recovery CDs.

Ubuntu Edgy live/installer boots normally from CD-R using external IBM USB DVD-ROM/CD-RW. SATA hard disk is recognised, gdm and Gnome start normally. Xorg is configured with i810. DRI works (glxinfo|grep rendering). Gigabit ethernet works, uses e1000. Wireless works, wpasupplicant is installed, network-manager --- not. ALSA sound works as long as modem is not disabled in BIOS.

Default 2.6.17-10-generic kernel supports SMP (which wasn't the case with Dapper). /proc/cpuinfo reports two CPUs: CPU0 and CPU1.

CPU scaling uses ondemand governor. Available frequencies are 1GHz and 1.5 GHz (/sys/devices/cpu/...) Should there be more frequency steps/lower minimum available?

Laptop-mode is not enabled by default. See /etc/default/acpi-support, (re)start laptop-mode, then check /proc/sys/vm/laptop-mode.

Fully charged battery provides just 2.5+ hours of mostly idle operation. Still very low compared to 4 hours in another OS on the same laptop...

With some changes to laptop-mode settings, 8 cell battery can last upwards of 6 hours.
