Choosing The Correct Laptop Adapter For Your Laptop

Choosing the correct laptop adapter is all a matter of voltage, output power, and proper connection. If all of these things do not match the original specifications of your computer, than a new laptop adapter will likely not work on your machine and may potentially cause a lot of damage. In the end, most replacement adapters will have a list of computers they are compatible with.

The first thing to consider for the laptop adapter is the voltage. The easiest way to check this is to turn the computer over and see if there is a voltage listed anywhere on the bottom of the machine. A sticker may be affixed with this information and other similar laptop specs listed. It should be a number with a V attached to it, such as 19.5V. This information is also available on the original adapter, if it is available.

The second thing to look for is the current output needed for the laptop adapter. This number will have an A of mA associated with it. For example, it may say something like 4.7A or 950mA. These numbers ensure that the power going to your machine will be acceptable and keep it operating within normal parameters. Not paying attention to either of these numbers could cause the electrical systems in the computer to malfunction and quit working altogether.

Once these two issues have been settled, the other important step is simply to make sure the connection fits the port in your computer where it is to be plugged in. The voltage and output current of the laptop adapter will not matter if it is not able to be connected. If ordering online or if you do not have your computer, it is advisable to check this out as soon as possible.

Many may choose the safest route possible and go with a replacement laptop adapter directly from the manufacturer, if available. While this is a good option, these parts may be more expensive than others that may be available from after-market manufacturers. Further, as long as the numbers match, all should work nearly the same and be just as safe and effective.

Another thing to consider is whether you want an AC laptop adapter or DC adapter. An AC adapter is made to be plugged into any standard electrical outlet such as those in a home or office. The DC adapter is made for automobile use.

Laptop Service – Online Security Tips Best Practices

Keeping your laptop safe from online threats requires some preventative and active controls. Follow these general tips to keep your laptop and the valuable data safe and secure.

1. Install Anti-virus Software

Anti-virus software is designed to identify, neutralize and eradicate viruses that can harm your laptop, destroy your data, or exploit vulnerabilities that give spammers and fraudsters access to your accounts and personal data. Choose a good quality, anti-virus program such (Norton Security, Karspersky Security, or Webroot Security. Be careful when you download a program and make sure it is from a reputable site that you trust or go to the manufacturer’s website. To be effective, update the anti-virus software regularly to get the latest virus definitions (best practice is to set it up for automatic updates-this way you will not forget and always will be protected). Most commercial anti-virus programs have the automatic update feature and we recommend that you use it. For your convenience, schedule scans to run when you are not using the laptop, because the resources it takes to run a scan can slow you down your system.

2. Step: Turn on the Firewall

A firewall protects your notebook from Internet traffic entering in or information leaking out. You can use two firewalls (Hardware) and stack them up to increase the security level. Also the level of traffic allowed should be set to “recommended” or HIGH if you so please. There are software firewalls that can be also used such ZoneAlarm and Webroot Firewall, but while anti-virus software scans emails and files, a firewall acts as a guard dog, keeping your system safe from unauthorized entry. It also blocks communications to and from your laptop. To ensure the highest protection, it’s best to use both a firewall and anti-virus/spyware software.

3. Install Anti-spyware Software

Spyware and adware can cause a variety of things like annoying pop-ups and browser crashes, the installation of unexpected toolbars or icons, redirects to inappropriate sites, keys that don’t function, random error messages, browser freezing and sluggish performance. These types of malware are installed on your computer without your consent, and can monitor and in some cases control your laptop. To lower the risk of infection, use anti-spyware and adware software such Norton Security, Karspersky Security or Webroot Security Essentials. We recommend using at least two different programs for broader security and coverage.

Tips for safer surfing the WWW:

Use a firewall, anti-virus and anti-spyware software and keep it up-to-date Keep your operating system, browser and other software up-to-date and patched Don’t open email attachments or click on an email link from unknown senders (”Use Common Sense”) Scan all email attachments and downloads with anti-virus software Don’t download and install programs of unknown origin or innapropriate sites Disable Java, JavaScript, and ActiveX if possible Scan and Backup critical data often to CD/DVD or External Hard Drive (USB-SATA) Perform regular maintenance on your computer like disk cleanup, defragmentation, and system scans Create a boot disk in case your computer is damaged or compromised Protect your PC-Host file with security essential software or by editing policies correctly.
