|RAM||Up to 8GB|
|HDD||Up to 750GB|
|Graphics||AMD Radeon HD 6650M
AMD Radeon HD 6720G2
|Optical Drive||Not Tested|
|Graphics Chip||Works, with problems||Open source driver works best with kernel>=3.11 and Mesa>=10.0|
|VGA Out||Works, with problems|
|HDMI Out||Works, with problems||Sound may be distorted with open source driver|
|Bulti-in Microphone||Works||Mic is sensitive, lower volume for use in VoIP programs|
|Microphone Jack||Not Tested|
|Wireless||Works, with problems|
|Suspend/Resume||Works, with problems||Laptop panel blank on resume - external displays work fine. For kernel=3.13.*, GPU hangs on suspend, resume and shutdown|
You can install and use the proprietary AMD Catalyst drivers, where the problems with the open source driver may not occur.
Versions that work well: (14.2 beta)
(Version 12.3 seems to work quite well, with very good performance as well)
This section details the open source GPU driver's problems and workarounds.
TLDR: Use following kernel parameters for good stable use.
acpi_sleep=s3_bios (ensures that laptop screen will work again after suspend and resume)
radeon.runpm=0 (disables automatically switching off GPU due to GPU hangs) - for linux >= 3.13
radeon.dpm=1 (new power management code)
Recommend using Linux kernel >= 3.11 - proper power management resulting in better performance and lower temperatures. Requires AMD GPU firmware as well, should be included in distribution's Linux firmware package.
All firmware can be found here: http://people.freedesktop.org/~agd5f/radeon_ucode/
For Linux kernel >= 3.13 , GPU hangs during suspend, resume and shutdown. As a temporary workaround, boot with kernel parameter radeon.runpm=0. This will turn off the runtime power management that automatically shuts off the dedicated GPU (if present) when unused. It does not affect dpm (the new power management code).

Laptop screen is blank (backlight off) after suspending and resuming when using the open source driver.
Workaround: Use kernel parameter acpi_sleep=s3_bios
Glamor 2D acceleration may not work properly - in any case, it is optional and by default EXA is used.
Hybrid/Dual graphics - With the open source driver, the dedicated GPU is not currently used. You can try using it by exporting DRI_PRIME=1 and launching a program. (e.g) DRI_PRIME=1 glxinfo
Overall works well when using latest stable software.
