Build and Design

Compared to most notebooks the Qosmio is an extremely flashy computer. The display cover is glossy black with the Qosmio brand name embossed over it; proudly announcing its name to those around you. Opening the laptop reveals its glossy white palm rest and keyboard surround, nicely contrasting the top cover, with chrome dials and touch-sensitive selection buttons to control various functions. Bright blue LEDs illuminate all soft media buttons, as well as the volume dial and power switch when the unit is powered up. The LED’s can be disabled if the user so wishes, by pressing a soft-key above the keyboard.

Underneath the glossy plastic shell, bright blue LEDs, and chrome knobs is an alloy frame that supports the entire laptop. Many laptops these days have a metal alloy frame and it usually results in a very durable case having little flex. However, even though the Qosmio has this alloy frame, it seems the frame isn’t thick enough as there is plentiful flex to be found. The palm rest, the keyboard, and bezel around the keyboard all bow in with moderate pressure. The flexing becomes most apparent when the laptop is not on a flat surface. With one corner hanging off of a desk surface, weight from your wrist and arm while typing will bend the corner down a quarter inch or more. For such a high price tag you would expect better build quality when other Toshiba models costing a third less feel more durable.


Being a multimedia oriented machine, this laptop revolves around a high quality display. Coming in at 17”, with a WUXGA resolution, and a glossy finish it is something to behold. Wide horizontal viewing angles let you share movies with friends next to you, but limited vertical angles had the screen dim sharply as you moved to steeper vantage points. Colors were vibrant, whites were pure, and backlighting was even across the screen. Backlight bleed was only noticed at maximum brightness levels, but it’s very hard to notice this unless you really look for it.

Throughout the review period, the backlight failed by turning off multiple times. The inverter whined on startup and at seemingly random intervals the backlight would just shut off. The first time it happened I thought the machine had locked and shutdown, but noticed by looking closely at the screen the desktop was still visible. At first I thought it was a fluke, but after several occurrences it got on my nerves. With a price tag of $3,200, you would hope that flaws like this would be caught early in the manufacturing process. I’m hoping this was just an issue with our review unit.


The 4.1 speaker setup on the laptop is one of the best setups I have heard to date. Bass was clear and defined, midrange and high were both pretty accurate. I was able to get the volume quite loud before any distortion was heard, although with particularly loud bass you will get the plastic case to rattle.

The main speakers are located right above the keyboard, with the 2 smaller speakers located on either side of the LCD. The subwoofer is on the bottom side of the laptop near the left side.

Keyboard and Touchpad

The keyboard on the Qosimo felt large enough for comfortable typing, but could have had a dedicated number pad if the designers had relocated the volume dial and media controls. With its current layout there is plenty of extra whitespace around the entire typing surface to keep things uncluttered. The typing surface felt very solid and supported, and flexed much less than the rest of the body. Keystrokes required minimal pressure to recognize a key press, keeping my wrists stress free while writing. Typing was also quiet compared to some keyboards, so clacking away in a quiet room is not a concern.

The touchpad surface is large (3”x1.8”) allowing plenty of control in games and other mouse intensive activities. The two mouse control buttons provide a positive click when pressed, although I do prefer touchpad buttons with more travel. The fingerprint reader on this notebook was located between the buttons, staying out of the way during normal use.

Performance and Benchmarks

With only one Qosmio G45 configuration at the moment, you are limited to the base configuration. This leaves you with the fast, but nowhere near top end, Intel T7300. As such, some processor intensive benchmarks came up less than laptops well under its price bracket.

Super Pi comparison results:

Super Pi forces the prcoessor to calculate Pi to 2 million digits of accuracy, below are some comparison results so you can see how the Qosmio’s T7300 processor competes.

WPrime 32M comparison results

WPrime is a benchmark similar to Super Pi in that it forces the processor to do intense mathematical calculations, but the difference is this application is multi-threaded and represents dual core processors better.

Heat and Noise

Heat and noise with the Qosmio G45 were never overwhelming, even when the laptop was running benchmarks. From its massive size, it had a large surface to warm up gracefully, as well as acting as a passive heatsink. Fan noise stayed within reasonable levels, usually being drowned out by other office noises. During normal uses (web browsing) the laptop would warm up to a nice level, leaving most touchable surfaces 6-10 degrees warmer than room temperature. Shown below are IR temperature readouts of the upper and lower surface of the notebook as it was cooling down from a benchmark that ran 2-3 minutes earlier.

Mobile life on the laptop comes in short at 2 hours and 40 minutes, on the balanced profile and the screen brightness one notch down from top. If you want to watch a HD-DVD movie on a plane, your battery drops even lower to 60 minutes. With a machine of this size, if you are planning on doing much work away from an AC outlet I would suggest getting a spare battery.

Additional Features

The Qosmio G45 includes both an external HDTV tuner, and a HD-DVD Burner. The burner, being the most expensive item, probably drove its price up quite a bit. Both of these included items worked without issue when tested. The HDTV tuner clearly brought in 5 digital channels available inside my apartment, having a slight pause changing stations. The HD DVD burner was tested using the included Toshiba software, and burning 14 GB of data to a 15 GB disc took 55 minutes and 30 seconds. Not quite the fastest process compared to CD’s or DVD’s, but our single included HD-DVD burned successfully without making a coaster.

Input and Output Ports

Let’s take a visual tour around the ports of the Qosmio G45.

The Qosmio ranks up with the best of them in terms of bloatware. It comes with many free software programs, toolbars, and Toshiba utilities. One utility that feels especially bad is the dropdown bar that acts as a visual indicator for FN key control functions. When activating this bar either through moving the pointer to the top of the screen, or holding down the FN key, the system can sometimes lock for 5-10 seconds before the bar moves slowly down. Adjusting the backlight level for example becomes a heavy task for the notebook, whereas on other machines it takes a split second.


With its steep price, quality issues, and questionable durability, its hard to recommend the Qosmio G45 over other quality Toshiba notebooks like the Satellite X205 gaming notebook. The key issues that would change this decision, if fixed, are the flimsy chassis and buggy hardware failures. Another might be to offer a HD-DVD-rom drive instead of the burner, and really lighten the cost of the machine.


  • Screen great when operational
  • Gaming performance was more than adequate for the latest games
  • Speakers kick you know what


  • Problematic hardware and software
  • Screen backlight failures
  • Toshiba utilities that cause the computer to freeze
