MSI outs its latest GE620DX gaming laptop, orcs prepare for virtual slaughter

Spilled Mountain Dew on your last laptop during that marathon session of Starcraft II? MSI's got your back buddy, with its newly announced GE620DX. There's a serious bit of dedicated gaming punch lying under this notebook's brushed metal finish thanks to its 2GHz quad-core Intel Core i7 processor, an NVIDIA GeForce GT 555M card and the audio tag team of MSI Premium Sound and THX's True Studio Pro. In addition to its 15.6-inch 1366 x 768 HD display, this "dream machine" sports a 720p camera, an HDMI out port and USB 3.0. The company's also thrown in a GPU Boost feature, which frees up the internal graphics chip should you be running any graphics-intensive apps. Unfortunately, your zerg Swarm-slaying hands will have to wait for an official price and retail date, but when you do get a hold of it, make sure to keep that caffeinated brew far from the keyboard.

Help Needed: Anybody got a Toshiba Satellite...

Help Needed:
Anybody got a Toshiba Satellite P750 (P750/02J) running Linux that could upload the ACPI info as explained here?

To compile your DSDT and SSDTs information, install if you haven't already the acpidump and iasl tools:

sudo apt-get install acpidump iasl
### or
sudo yum install pmtools iasl

Then run the following commands on a bash terminal:

mkdir ~/acpiinfo ; cd ~/acpiinfo
sudo acpidump > acpidump.txt
# enter password
sudo acpixtract acpidump.txt
ls *.dat | while read i; do iasl -d "${i}"; done
name=`sudo dmidecode -s system-product-name`
mkdir "${name}" && cp *.dsl "${name}"/
tar czf "${name}.tar.gz" "${name}"/ && ls -l "$( pwd )/${name}".tar.gz

This will create a tar.gz file that you can attach to the bug report.
Finally, for posting the information in the bug report, you can check the laptop and graphics card model identifiers with these commands:

sudo dmidecode -s system-product-name && sudo dmidecode -s system-version
lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA

This information will allow the full development of hybrid graphics features for Linux. Thanks for your help!

HP to offer a switch for their line of HP AMD BACON hybrid laptops

Our team member E. P. has pointed out that HP will issue a BIOS update that will allow users to switch from the default Dynamic mode to Fixed mode in HP AMD BACON hybrid graphics laptops:

We understand that there is a concern about switchable graphics and OpenGL functionality.


Switchable Graphics:

HP has a document about how to configure the ATI® Mobility Radeon® Switchable graphics feature. This

document also describes the differences between fixed and dynamic switchable graphic modes and how

to use each effectively.



Open GL Functionality:

To operate certain OpenGL applications, you will need to install the latest graphics driver (SP 53025)

which can be found here: . This download

provides Intel Graphics Driver version to support the Intel GPU in HP notebooks with

switchable graphics. The AMD graphics card in newer HP Pavilion dv6 and dv7 Series models may not

run certain Open GL software.


Update: There is a BIOS update in the works that will allow you to switch from the default Dynamic mode to Fixed mode. Switching to Fixed Mode will allow you to run Open GL programs on the AMD Radeon graphics processor. We will let you know as soon as this is available.

Acer TravelMate 8481 with nvidia optimus @

Acer TravelMate 8481 lands late August, £700 price tag in tow

Back in May, we caught a glimpse of Acer's TravelMate 8481, rocking an extra thin bezel and 13 hours of battery life for the road-weary sojourner. At the time, Acer was touting a mid-June launch, but we've just received word that the Core i7-packing notebook won't make it into carry-ons until late August. As of now, we've only got UK pricing -- £699, to be exact -- leading us to wonder when the thing will make the journey stateside. As per usual, we will keep you abreast of the details as they roll in. Until then, you can peep the full PR after the break.

Sony VAIO Z series 2011 includes hybrid graphics option via a docking station

For the seasoned Linux users, the Sony VAIO Z series has seen 3 updates in the last 3 years, the sony-vaioz-09, sony-vaioz-10, and now the sony-vaioz-11, sporting a docking station with a discrete AMD graphics card:



Sony’s New VAIO Z Series Is Available Now, Lightest 13-inch High Performance Notebook

Sony’s much anticipated VAIO Z Series ultraportable notebooks have arrived. This new VAIO Z Series is touted as the “world’s lightest 13-inch standard voltage PC” and features an ultra slim design that’s thinner and lighter than the MacBook Air while packing in high performance specs with Intel’s latest Sandy Bridge Core i5 and i7 processors.


The new VAIO Z Series notebook is designed to work in tandem with a Power Media Dock that delivers the power of an AMD Radeon HD 6650M graphics card with 1GB VRAM, a slot loading optical drive, one USB 3.0 port, two USB 2.0 ports, HDMI, and VGA ports. Thanks to this pairing, the new Z Series is now a half pound lighter than its predecessor and weighs only 2.5 pounds.

The sleek chassis measures just 0.66-inch thin and is made of a combination of aluminum and carbon fiber. It is designed to be fully flat without any protruding ports or unnecessary seams. Battery life is rated for up to 8 hours and can be boosted to 16 hours with the purchase of an optional large-capacity sheet battery that attaches flush on the bottom.

The notebook is equipped with the latest Intel Sandy Bridge Core i5 and i7 processors that can be turbo boosted to 3.4GHz and has dual-channel SSD drives with RAID tehcnology. It also sports Intel’s Light Peak port, also known on Apple products as the Thunderbolt port, that promises up to 10Gbps of blazing fast bi-directional data transfer speeds.

Other things to note include the notebook’s 16:9 aspect ratio display that’s available in either 1920×1080 or 1600×900 resolution levels with anti-glare coating. The notebook comes in three colors carbon black, carbon indigo, and premium carbon black. It is available now for pre-orders at Sony’s website and retails starting at around $2000.

Gateway laptops with nvidia optimus and AMD Fusion configurations @

Gateway updates its ID and NV laptops with USB 3.0, Sandy Bridge and Llano internals

Acer's had its day (or two) unveiling back-to-school laptops, and now it's its sister brand Gateway's turn. The outfit just announced the 15.6-inch NV series and the 14-inch ID47, both of which include USB 3.0 and a choice of Sandy Bridge processors. (In the case of that entry-level NV, you can also opt for one of AMD's fresh-off-the-line Llano chips.) But the company did more than just give its notebooks a spec bump -- it also tweaked their designs, adding a chiclet keyboard to the NV series, while the metal-clad ID's trackpad is 20 percent larger and no longer glows like a mood ring. The ID47 also has a 14-inch display crammed into a chassis usually paired with 13.3-inch panels, as well as a non-removable battery that promises up to eight hours of juice. (The NV is rated for up to four hours.) And, in an unusual twist, our friends in Canada will get additional choices, including a 15.6-inch version of the ID, as well as select models with NVIDIA Optimus. Both the ID47 and NV55 / NV57 are available now, with the ID starting at $629.99 and $799 Canadian, and the NV fetching $529.99 and $499 Canadian. Check out the various configurations after the break, with lots 'o photos below.

HP dv6z with hybrid crossfire @

HP Pavilion dv6z Quad laptop with AMD Llano

AMD's Llano platform might not satisfy everyone's power-lust when housed in a desktop, but stick one of these all-in-one beauties in a laptop and you're good to go. The new HP Pavilion dv6z Quad notebook -- one of 11 new Fusion-powered models from HP -- is a case in point, having just arrived at the company's online store. The base model promises battery life of up to almost six hours, "discrete-class" integrated Radeon graphics with 512MB of video memory, and a 1.4GHz quad-core processor that can be clocked up to 2.3GHz using AMD's Turbo technology. Oh yeah, and there's the real benefit of switching to AMD: that base configuration costs just $650, versus a minimum of $999 for the Intel-equipped dv6t. For the money, you'll also get 6GB of DDR3 memory, a 640GB 5400rpm HDD, a 1366 x 768 display (yes, a glossy one), HDMI output, and a pair of USB 3.0 ports in addition to two of the USB 2.0 variety. We ought to clarify that the sexy steel gray version on the left will cost you $25 extra, but hey, who wants to be "umber gray?"
