Setting Display Resolution and Refresh Rate for Dell laptop

To display a program at a specific resolution, both the graphics card and the display must support the program, and the necessary video drivers must be installed.
Before you change any of the default display settings, make a note of the default settings for future reference.NOTE: Use only the Dell-installed video drivers, which are designed to offer the best performance with your Dell-installed operating system. If you choose a resolution or color palette that is higher than the display supports, the settings adjust automatically to the closest supported values.
1 Click the Start button and click Control Panel.
2 Under Pick a category, click Appearance and Themes.
3 Under Pick a task..., click the area you want to change, or under or pick a Control Panel icon, click Display.
4 In the Display Properties window, click the Settings tab.
5 Try different settings for Color quality and Screen resolution.NOTE: As the resolution increases, icons and text appear smaller on the screen.
If the video resolution setting is higher than that supported by the display, the computer enters pan mode. In pan mode, the entire screen cannot be displayed at one time. For example, the taskbar that usually appears at the bottom of the desktop may no longer be visible. To view the rest of the screen, use the touch pad or track stick to pan up, down, left, and right.NOTICE: You can damage an external monitor by using an unsupported refresh rate.
Before adjusting the refresh rate on an external monitor, see the user’s guide for the monitor.You can attach an external monitor or projector to your computer and use it as an extension of your display (known as "dual independent display" or "extended desktop" mode).
This mode allows you to use both screens independently and drag objects from one screen to the other, effectively doubling the amount of viewable work space.For more laptop ac adapters information, you can visit here: Delta SADP-65KB AC Adapter(Input: AC100-240V (worldwide use);Output: DC19V 3.42A )Dell 3K360 AC Adapter(Output: DC20V 4.5A;Power: 90W)Dell Inspiron 8100 AC Adapter(Input: AC100-240V (worldwide use);Output: DC20V 3.5A)Dell N5825 AC Adapter(Input: AC100-240V (worldwide use);Output: DC19V 3.16A )Dell PA-1650-050 AC Adapter(Input: AC100-240V (worldwide use);Output: DC19.5V 3.34A )HP 391172-001 AC adapter(Input: AC100-240V (worldwide use);Output: DC18.5V 3.5A )HP 391172-001 AC adapter(Input: AC100-240V 50-60Hz Output: 18.5V 3.5A Power: 65W)

Will A123 Systems Lands Battery Deal with Fisker Automotive?

“Fisker Automotive selected A123 because of the company’s ability to meet our performance needs and rapidly scale to our production volume,” said Henrik Fisker, Chief Executive Officer of Fisker Automotive. “Fisker is committed to developing environmentally friendly cars that don’t sacrifice style or performance. A123’s technology will ensure the Karma delivers.”
Fisker is aiming to make the Karma one of the cleanest, most fuel-efficient cars in the world while still offering industry-leading style and performance. Clearly, selecting the right battery manufacturer for the Karma is a large part of achieving what Fisker is setting out to accomplish.
The Fisker Karma is expected to have a range of 50 full-electric miles on a charge of A123’s lithium ion battery system and a total range of 300 miles with an on-board generator turned by a traditional but efficient four-cylinder gasoline engine. The Karma features 403hp and is designed to go from 0 to 60 mph in about six seconds, reaching a top speed of 125 mph.
Following up on what was an eventful 2009 for Massachusetts-based A123 Systems, the up and coming battery manufacturer has started off the new decade by striking a battery supply agreement with Fisker Automotive. The recent recipient of nearly $250 million under Pres. Obama’s American Recovery and Reinvestment Act will manufacture battery systems for the Fisker Karma Plug-in Hybrid Electric Vehicle, which is slated for release later this year.See more laptop ac adapters, laptop accessories information on usadapter, or just visit here: Acer Aspire 1410 AC Adapter(Input: AC100-240V (worldwide use);Output: DC19V 3.42A;Power: 65W;Connecter size:;Internal Diameter: 1.5mm ultra slim;External Diameter: 5.5mm )Gateway SADP-65KB B Adapter 65W(Input: AC100-240V (worldwide use);Output: DC19V 3.42A )Toshiba PA3396U-1ACA AC Adapter(Input: AC100-240V (worldwide use);Output: DC19V 3.42A)HP 391172-001 AC Adapter(Input: AC100-240V (worldwide use);Output: DC18.5V 3.5A )HP 371790-001 AC Adapter(Input: AC100-240V 50-60Hz Output: 18.5V 3.5A Power: 65W)Apple ADP-60AD AC Adapter(Output: DC16.5V 3.65A Power: 60W)Dell Inspiron 1505 AC Adapter(Input: AC100-240V (worldwide use)Output: DC19.5V 3.34A)

High-end laptops are lucky to squeeze 3 hours of run time for long battery life

Asus had on display at CES a performance-oriented laptop the company hopes will redefine the high-end genre. The UL80JT, as it's currently called, can switch back and forth between a high-end Nvidia GeForce 310 and Intel's lowly GMA graphics. Combined with a Core i7 CPU capable of re-clocking itself on a second-by-second basis and other micromanagement tricks, Asus claims users can expect up to 12 hours of run time.

High-end laptops are lucky to squeeze 3 hours of run time out of a single charge, and if you're looking for ultra long battery life, your best bet is a netbook. Or is it?

Even cooler, the whole process is transparent to the user, meaning you don't have to fiddle with power settings. The laptop decides for itself when to clock the dual-core Core i7 chip up or down and when to switch between graphic chips, and while we're skeptical we'd actually see 12 hours of run time, we would expect the UL80JT to run a lot longer than a typical high end notebook.

Acer’s 8.9-inch Aspire One has largely been accepted as the sales leader in the netbook market. It’s been so hot that Acer, trying to fix what’s not broken, is looking to release a larger Aspire One AOD150, which will boast a 10.1-inch screen and a doubled battery life for the same $350.

The new Aspire One will have an Intel Atom N270 under the hood with integrated 945GSE graphics, 1GB of DDR2, a 160GB HDD and Windows XP Home edition. And to power it all, there will be a six-cell, 4,400mAh lithium-ion battery that will keep it all moving for up to six hours.
