UEFI

This laptop is UEFI-capable. The following articles were found to be helpful in setting up this laptop to boot in UEFI mode:

Earlier kernels (before 3.0) were unable to boot in UEFI mode on this laptop unless "noefi" was passed on the kernel line. Later kernel versions should boot correctly.

  • The keyboard (including number pad), power button, audio hotkeys, webcam, audio, and microphone were found to work flawlessly without any intervention.
  • The "Track Stick" performs as expected. The touchpad supports synaptic extensions, but not multitouch.

SD Card Reader

As of Kernel 3.0, the SD Card Reader does not react when a card is inserted. This can be rectified by removing the Firewire driver from the kernel:

sudo modprobe -r firewire_ohci

To make the change permanent, remember to blacklist the firewire_ohci module (see Blacklisting).

Even with this fix, some corruption has occurred on certain SD cards when using the drive, along with seemingly related kernel panics. It would appear than driver support is lacking for this device.

This may be related to the following kernel warning, which appears at boot time:

sdhci-pci 0000:09:00.1: Invalid iomem size. You may experience problems.
