This model is actually very similar to the VivoBook S451LB - in fact, the Windows reports the laptop as an S451LB, and even the BIOS updates released for it are identical to those for the S451LB.
In spite of these similarities, I have opened this new page to allow those who are less informed about the two models' similarities to quickly spot it at a glance.
Interestingly enough, this model is not listed on Asus' web site, although it is listed in its support site and printed brochures (marketed as an Ultrabook, despite not actually having the Ultrabook sticker).

Note: Since this model is extremely similar to the VivoBook S451LB, the following link should serve as a suitable reference for the hardware specifications.

*Note: Because I was unwilling to fiddle with the partitions on the default HDD, I swapped it out for a Samsung SSD 840 EVO 250 GB (MZ-7TE250). It is important to note that only 2.5” disk drives of height 7 mm will be accepted - installing a 9 mm drive will prevent the cover from being closed properly.
|Graphics||IGP: ✔ |
|Optimus support requires blacklisting of nouveau and installation of at least nVIDIA 331.38 drivers and Bumblebee. There is no BIOS option to disable the dedicated GPU.|
|HDMI Out||✔||Both video and audio outputs are functional. Port is driven by the Intel IGP. Color saturation appears to be weak, possibly due to limited RGB mode being set in software?|
|DisplayPort||N/A||Inbuilt screen is driven by embedded DisplayPort. No external DisplayPort interface.|
|Optical Drive||Reading: ✔ |
Writing: Not Tested
|Sound (Inbuilt speakers)||✔|
|Microphone-In Port||Not Tested|
|Ethernet||✔||Port takes a long time (~5 minutes) to initialize, but once it is up speeds are normal.|
|Bluetooth||A2DP: ✔ |
File transfer: ✔ (for supported file types)
Others: Not Tested
|USB||USB 2.0: ✔ |
USB 3.0: ✔
|Firewire||N/A||No Firewire port.|

UEFI:-prefixed entry corresponding to the optical drive.
/dev/sda <disk name>) and not any sub partitions (e.g.
/dev/sda1). This is because UEFI mandates that all bootloaders be installed to the same EFI partition on disk. Once installed, the laptop will boot to the Grub 2 bootloader instead, with an entry for booting into Windows 8 (only tested on Linux Mint 17, use of this method on anything else is solely at your own risk. Test it out with a virtual machine first to be on the safe side).
driver-manager) first, followed by Bumblebee (otherwise Bumblebee would trigger the release 304.xx drivers to be installed instead, which don't support the GK208M). Once installed, ensure that the Intel GPU is selected in the PRIME Profiles tab in NVIDIA X Server Settings - Bumblebee will enable the nVIDIA GPU as necessary.
With the exception of some quirks and minor functionality loss, the VivoBook K451LB works reasonably well with Linux Mint 17 MATE (
3.13.0-24-generic kernel) in UEFI mode.
