Tip & How-To about Computers & Internet

How to make your Laptop Battery last longer

1. Turn off Wi-Fi and BlueTooth - Most laptops have shortcut keys to instantly disable wireless networking.
2. Don't play computer games, music or DVD movies - Multimedia activities drain laptop batteries.
3. Disconnect all external device like PC Card modems, Firewire, USB devices and optical drives. Use the notebook touchpad instead of an external mouse.
4. Adjust your screen brightness - Dimming your display saves battery power.
5. Tweak Windows Power Options - Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity.
6. Decrease or mute the Laptop Speaker Volume.
7. Turn off all scheduled tasks.
8. Turn off Auto-save features in Microsoft Office and other applications.
9. If your PC has a built-in wireless card, turn it off or disable it when not in use.
10. Programs that are run from a CD or DVD can be copied to and run from the hard drive, which typically consumes less power than an optical drive.

Enable / Disable an Enterprise Laptop's Wi-Fi
Wi-Fi, short for Wireless Fidelity, is networking technology that allows you to connect to the Internet. If you have a wireless-enabled Latitude computer you can connect to the Internet when in range of an access point called a hotspot.
When not in use your Latitude's wireless card should be disabled. By disabling Wi-Fi, you will receive two benefits:
Start-up times will be much faster.
If the wireless card is ON and you are out of the office (not connected to your normal, wired connection), the laptop will try to use the Wi-Fi network during the login process to run the various start-up scripts, etc. It will eventually time-out (fail). By having the wireless card turned OFF, the start-up process will be much faster.
Computer will not continually search for a wireless network (and waste battery life).
If you are in the office (connected to your normal, wired connection) or in a location where there is no wireless hotspot, you don't need to have the computer waste processing power by looking and looking for a wireless hotspot. By disabling Wi-Fi, you will gain a little more power for your other tasks. In addition, you will maximize your battery operating time by disabling wireless activity.
NOTE: After your Latitude has started up completely, you can ENABLE the wireless card and connect to a wireless hotspot. For example, a wireless router at your home or at a local coffee shop. If you have connected to this hotspot previously, the wireless card should connect automatically for you.
NOTE: Once you have the wireless card enabled, before you shut down the computer, you should again DISABLE the card. The computer will then be ready for the next time you turn it on with wireless turned off.
Enable / Disable with Hardware Switch
The more recent Latitude models have a wireless switch to enable or disable wireless network devices and the
Wi-Fi Catcher Network Locator.
Dell Latitude E6420 and E6520 Series
These laptops have a small switch on the RIGHT side of the keyboard. The switch is toward the front of the laptop. The Wi-Fi Catcherâ„¢ icon will is above the keyboard. You will see a lit radio tower if the wireless switch is enable

bluetooth peripheral device driver


Sai Ch Krishna,

Depending on the system. The bluetooth would have to have been purchased at point of sale. The wireless and the bluetooth are turned on by a wireless switch on the side of the computer. If needed you can reinstall the drivers. Also, make sure bluetooth is turned on in the bios. Below is more information.
Wireless Switch

Wireless Technology The Latitude D630, D631, and D630c system ships with a wireless feature called the wireless switch. It is located on the left side of the system next to the IEEE 1394 connector. When used in combination with the Dell 38482; Quickset utilities, this switch enables or disables the wireless LAN, wireless WAN, and Bluetooth cards in the system or searches for all wireless networks in range.
To scan for a Wi-Fi wireless LAN, slide and hold the switch in the momentary position for a few seconds. The Wi-Fi Catcher network locator works whether the computer is turned on or off, in Hibernate mode, or in Standby mode, as long as the switch is configured through QuickSet or the BIOS to control Wi-Fi network connections.
Because the Wi-Fi Catcher network locator is disabled and not configured for use when the computer is shipped, it must be enabled and configured through the Dell QuickSet utilities to control Wi-Fi network connections.

Wireless Switch LED Settings
The LED on the wireless switch works even if the system is off. A user can activate the switch and have it scan for networks without going through a complete boot process. The switch can be set to detect for only certain wireless signals, such as WLAN only, WWAN only, Bluetooth only, or any combination of these. This is set in the BIOS under the Wireless section.
The LED indicates the presence of a network as follows:
  • Flashing green - The system is searching for a signal.
  • Green - The system has detected a wireless signal and has good strength.
  • Yellow - The system has detected a wireless signal, but it is moderate to weak in strength.
  • Red - The system failed to detect a wireless signal, or the wireless signal is extremely weak.
Thank You,

wlan card disabled


The Dell Latitude E6400 laptop comes with an Intel Core 2 Duo processor for fast computing and an NVIDIA graphics card for video playback, gaming and Web browsing. The laptop has a built in Wi-Fi card, letting you connect to the Internet on-the-go. However, if you're unfamiliar with Dell or the laptop's factory installed Windows Vista operating system, you might not know how to enable to Wi-Fi.

Slide the switch on the side of the laptop toward the front of the laptop. This switch enables Wi-Fi connectivity on the Dell Latitude E6400. When switched into the back position, the Wi-Fi is turned off. Turn on your Dell Latitude E6400 laptop and log into Windows Vista. Click on the Windows "Start" button. Click on "Wireless," located in the Start menu's "Show" list. A list of currently broadcasting wireless networks appears on screen. With your Wi-Fi enabled, you can connect to any of these available networks. Secured networks ask you for a password when you click "Connect," while unsecured networks connect automatically.

short battery life


This model is 18months old now and if you leave your notebook plugged into your adapter all or most of the time, the battery will degrade.
Like all chemical reactions, they diminish with time.
Ebay host a lot of suppliers looking for customers and have keen prices.
Hope that helps.
