Here are a few steps you can take to stretch out the available electrons in your
battery.
Adjust your power settings:
To take advantage of power-saving features the manufacturer has built into your
laptop, you'll want to consult your user manual, as they vary from one machine to
the next. But you can also give battery life a significant boost by tweaking the
power options in your operating system.
Here's how:
Windows Vista gives you control of how your laptop manages power by bundling
various hardware and system settings into three default power-plan options:
Balanced offers full performance when you need it, but conserves power when your
laptop is idle.
Power saver gives the biggest boost for extending battery life, but results in
lower performance.
High performance maximizes system performance at the expense of battery life.
Switching between plans is a simple two-step process:
1. Click the battery meter icon, located in the notification area on the Windows
taskbar.
2. Select one of the three default power plans: Balanced, Power saver or High
performance.
Windows XP offers two power schemes designed for laptops and other portable PCs:
The Portable/Laptop power scheme minimizes power use to conserve battery life, but
adjusts as your processing needs change so system speed isn't sacrificed.
The Max Battery power scheme also minimizes power use but doesn't adjust to
changing processing demands. This setting is meant for situations requiring
minimal processing, such as reading documents or taking notes.
To switch from the Portable/Laptop power scheme to Max Battery:
1. Click Start, and then click Control Panel.
2. In Control Panel, verify that you're in Category view, and then click
Performance and Maintenance.
3. In the Performance and Maintenance window, click Power Options.
4. On the Power Schemes tab of the Power OptionsProperties dialog box, click the
arrow under Power Schemes, and then click Max Battery.
5. Click OK.
Care and maintenance of your battery
There are a few best practices that can help preserve battery life:
-Keep your laptop battery out of extreme heat.
-Clean the battery with dry cloth, especially at the metal connectors.
-Defrag your hard drive regularly so it runs efficiently.
-Clean your battery contacts with rubbing alcohol periodically.
-Use Hibernate mode rather than Standby mode.
-When plugged in to the AC outlet for a long period of time, Take out the battery
from the system.
-Fully discharge the battery once a month by unplugging the AC power cord. After
that, charge it again completely.
Saving power on the fly
Here are some quick things you can do for short-term gain when you suddenly
realize you don't have enough juice to last through a meeting or plane ride:
-Dim your display; the less brightness the less power consumption.
-Close down unessential programs and keep graphics use to a minimum.
-Remove devices you aren't using, such as a USB flash drive or a DVD.

HOW TO PROTECT YOUR COMPUTER FROM HACKERS
It's dead easy to get a computer these days but maintaining the computer and protecting your data both offline and online requires a lot of work. However there are certain precautons you can take that will guarantee a reasonable degree of security.
-Your (Internet Protocol) IP address acts as a major source of information for hackers. Your IP is visible to almost anyone on the internet when you visit sites. It is advisable to key in anonymous proxies in your browsers or use anonimity softwares while surfing the net.
-Always update your anti-virus software as new viruses are developed everyday. It is also important to have a reliable firewall software.
-Passwords are supposed to act as a means of security but you have to secure it. How? Never use a nickname, a family name or a word that can be guessed easily. Use a combination of letters, figures and symbols. This will make your password hard to crack.
-Never visit suspicious sites. Never make payments in a site with expired or invalid ssl certificate.
-Try as much as possible not to open spam mails as some may contain viruses.
-Disconnect your internet connection when not in use as this will reduce the chance of your computer getting hacked.
-Regularly check your list of installed progrms as someone might install a keylogger on your PC.
Hackers can plant spywares on your computer, get your credit card and bank details, delete your files, infect your computer with viruses that might crash your OS. It is way better to prevent these from happening as some damages might be irreparable.
