Dell Latitude D630 Laptop battery life time can be increased or decreased depending on the applications and tasks that you have your laptop doing. For example, if you are playing a DVD movie, much power is being used, shorter time will your Dell Latitude D630 battery be used. If you are burning a CD-R/CD-RW or playing a full screen 3D video game, much power is being used. All these things take more power and in effect lessen the amount of time that you have in “portable” mode.

It is best to try to plug the laptop into the wall if possible in these situations. Remember that you can also get car power adapters for your laptop; this will charge your Dell Latitude D630 battery and power your laptop while you are on the road. Programs that take little power (giving you longer laptop battery life) include word processing programs like Microsoft Word or Corel Word Perfect, Microsoft Excel, Microsoft Access, Outlook Express, Internet Explorer, AOL, CompuServe, or any similar programs. Even the colors displayed on your screen can affect your Dell Latitude D630 battery life. Lighter colors take more power to produce. External connections such as USB Mice, USB Scanners, Memory Cards, Zip Drives, etc. all take more power from your precious Dell battery life. Keep these things in mind when power is of the essence.

In this month's technical report, we take a look at the new EOS 5D Mark II camera, announced on September 17 and scheduled to go on sale at the end of November.

Development objectives
The EOS 5D Mark II (Photo 1) was developed as a complete redesign of the original EOS 5D, which went on sale in October 2005. The development objectives for this full-frame, high-resolution digital AF SLR are listed below.

Full-frame sensor and fine image detail and quality
· 35mm full-frame 21.1-megapixel CMOS sensor
· DIGIC 4 image processor for fine detail and natural color reproduction
· Full-time ISO range of 100 to 6400 (L: 50, H1: 12,800, H2: 25,600)
· Enhanced automatic image correction features

The EOS 5D Mark II is equipped with a large CMOS sensor (Photo 2) developed in-house that has an effective sensor size of 24 x 36 millimeters and boasts 21.10 effective megapixels. This newly developed sensor provides the highest image fidelity and definition available among digital SLR cameras today. While the sensor's basic specs - size, pixel count, pixel pitch - are identical to the EOS-1Ds Mark III CMOS sensor, it features a new RGB color filter, improvements to raise the sensor's sensitivity and lower its noise, four-channel read-out, and lower power consumption to support Live View shooting.

(2)DIGIC 4 boosts base performance levels
The newly designed DIGIC 4 image processor (Photo 3) gives the EOS 5D Mark II faster and richer signal processing. Not only does the DIGIC 4 accelerate the processing of the 21.10-megapixel images, it also achieves higher sensitivity and lower noise performance, allows for more auto image processing functions, and raises the performance level of many digital image processing functions including face detection, Full HD video capture, HDMI output, and UDMA support.

(3)Full-time ISO 6400 gives more shooting opportunities
The top end of the EOS 5D Mark II's full-time ISO range of 100 to 6400 represents a two-stop improvement over the ISO 100 to 1600 range on the EOS 5D and EOS-1Ds Mark III. The Mark II also offers ISO extension down to 50 in L mode and as high as 12,800 in H1 mode and 25,600 in H2 mode.

(4)Improved auto image processing features
The Mark II comes with the following new feature upgrades over the 5D.

Highlight Tone Priority mode
This mode prioritizes the reproduction of tonal information in highlights. It is a very popular feature in the EOS-1Ds Mark III and the EOS 40D.

Auto Lighting Optimizer
This auto image correction function has been available on the EOS Kiss X2 and the EOS 50D. In this model, the Auto Lighting Optimizer function also uses face detection, as does the EOS 50D.

Peripheral illumination correction
As in the EOS 50D, this function automatically corrects JPEG images for lens vignetting. This function will play an even greater role in the EOS 5D Mark II because its 35mm full-frame sensor is more susceptible to lens vignetting than the smaller APS-C sensor on the EOS 50D.
EOS Utility is used to register and delete lens correction data (the EOS 5D Mark II can store correction data for up to 40 lenses; it is shipped with data for 26 lenses). JPEG images are corrected in-camera automatically immediately after shooting. RAW images can be corrected after shooting using a computer and Digital Photo Professional's capture settings.

Faster noise reduction function
The noise reduction function is divided into four settings - Standard, Low, Strong, and Disable - as in the EOS 50D. In the Standard and Low settings, the noise reduction function has no impact on the maximum burst length during continuous shooting. This improvement is the result of the DIGIC 4's faster image processing.

(5)Three-inch Clear View LCD monitor
The Canon EOS 5D Mark II features a three-inch, 920,000-pixel LCD monitor (Photo 4) with a wide viewing angle and crisp resolution. An anti-reflective fluorine coating has been applied to the protective cover surface and additional anti-reflective coatings have been applied to the rear surface of the cover and on the LCD panel surface to create a clear, easy-to-view monitor that resists dirt and grime.
The monitor's brightness can be adjusted manually in seven levels or adjusted automatically using a dedicated light sensor (located below the monitor).

Advances in integrated sensor cleaning
The EOS Integrated Cleaning System (ICS) was developed on the basic concept of ''don't make, collect, or leave'' any dust in the camera. The EOS 5D Mark II uses the following four-stage cleaning approach.

(1)Limit the creation of dust
(2)Limit the collection of dust on the surface of the imaging sensor unit
(3)Shake off any dust that does adhere with ultrasonic vibrations (Photo 5)
(4)Obtain and append Dust Delete Data to images/remove dust spots automatically with software

Focusing and exposure
Focusing is performed before shooting starts in the same way as when shooting Live View stills. The exposure is controlled using the imaging sensor with the metering mode set to center-weighted averaging and Program AE for movies.

· Movie processing
The Picture Style (including any sharpness or saturation adjustments) set for Live View still-image shooting is applied to movies.

· Movie controls and file format
Pressing the SET button in Live View mode starts and stops movie recording. Movies are saved as .MOV files. The user can take still shots while recording a movie by pressing the shutter button (movie recording is interrupted for about one second).
About 12 minutes can be recorded in Full HD - about 24 minutes in SD - on a 4GB card. The camera can record a total of about 90 minutes at room temperatures with a fully charged LP-E6 battery pack, but continuous recording is limited to 29 minutes 59 seconds or a file size of 4 GB. Note that movie recordings assume the use of a CF card with an actual read/write speed of at least 8 MB per second.

· Audio recording
Sounds can be recorded with movies either in mono (real PCM) with the built-in monaural microphone or in stereo using an external stereo microphone connected to the external microphone input.

· Movie playback from the camera (recommended)
Because of the huge amounts of data, Canon recommends playing movies from the camera by connecting the camera to a Full HD TV with an HDMI cable. It is possible to play back movies on a computer using the bundled software (ZoomBrowser EX 6.2/ImageBrowser 6.2), but because of the amount of data, a high-performance computer (Core 2 Duo CPU and 2.6GHz clock or better) is necessary.

Advances in the battery pack and system accessories

LP-E6 battery
The Canon LP-E6 Battery (Photo 8) is a new 1800 mAh battery pack that is nearly the same size as the BP-511A but with about 1.3 times the capacity. The LP-E6 is able to communicate with the EOS 5D Mark II, enabling the user to confirm on the LCD monitor the battery pack model, the remaining capacity, the shutter count, and the recharge performance in the same way as on the EOS-1D/1Ds Mark III.
The system accessories listed below were also developed in tandem with the LP-E6 Battery Pack.
