Laptops are by the day becoming a necessity for many people to work. As a matter of fact, I recently got myself an HP Pavilion DV3700. And I must say, it has helped in my work as well as provided me with entertainment anytime I want. Regardless of being in the park, coffee shop or camping. However, I recently found the need to get another HP Pavilion DV3700 charger, thought it would be a walk in the park. Shock on me. There is a lot more to it that just waltzing into a shop and making a purchase. So I decided to research and share my findings to help those who may find themselves in the same problem due to their laptop adapters malfunctioning or just since they want to have a backup.

The don’ts while making a purchase

When looking for an HP Pavilion DV3700 AC adapter, I was tempted to choose a universal power charger. Well, as after some research there some things that stood out that make this a bad idea. They are not essentially wrong choice but it is what they do not provide that makes them a wrong choice. While they are made to be compatible with many different models of laptops, they are fall short in the specifics, which really matter if your laptop battery is to serve you for a long while.

Also do not choose cheap HP Pavilion DV3700 adapter as they tend to be faulty and do not last long. In addition you will want to stick to the make and model of your laptop to ensure that the adapter is compatible.

What to consider

The first thing that you should realize is that there are different connector types for different laptops. The connector types include:

  •      Molex connectors
  •      Cylindrical connectors
  •      Snap and lock connectors

To ensure you get the right connector tip, take down the model number of your laptop so that you make a specific purchase.

In addition, you should check o the voltage requirements of the laptop that you have. Different adapters come with different voltages, purchasing one with a higher voltage that that of your laptop can cause major damage. You should therefore check your laptop for the voltage it is built for.

HP Pavilion DV3700 power supply

Given the fact that I travel a lot to places where there power is not available, I require my laptop to store its power for a longer time. To help me solve this issue I discovered that power supplies can be upgraded to help your laptop store power for longer times, provided your battery is in good condition. Many make upgrades o the RAM, hard disks and graphics card and totally ignore this component. Consider making the upgrade and you will marvel at the results you will get.

Guide to Choosing a Dell Inspiron 1440 AC Adapter

My Dell Inspiron 1440 laptop makes my entertainment, office and my very important files, easily accessible to me as well as portable, as I can take it to just about any place that I see fit. Be it the park or a coffee shop. When purchasing my laptop, it came with its very own charger and adapter. However, I found myself in some bit of a situation when my Dell Inspiron 1440 AC Adapter got damaged and I had to buy another one and fast. Well, you may not have damaged your but having two chargers can be a good idea especially when you are travelling.

However, regardless of the reason that you have to buy the charger or Dell Inspiron 1440 adapter, you will realize that it is not as straight forward as you thought. I therefore took the liberty of doing some research and sharing the findings.

Connector type

The first thing that you should know before you set out to make a purchase is that there are several different connector tip types. They include:

  •      Cylindrical connectors
  •      Snap and lock connector
  •      Molex connector.

Model number

You should therefore know which type your laptop uses as it may be different from my Dell Inspiron 1440 charger port. For this, you will require to have the laptop’s model number. It is normally located at the bottom of your laptop and is usually on a sticker. If you do not find the number there, you could do a manual search in your computers system properties. This will help you get the right kind of charger.

Voltage requirements

In addition to the model number, you will have to have the wattage requirements for your laptop as different adapters come with different voltage settings. Buying an adapter with a higher voltage than that of your laptop can actually damage it. You wouldn’t want that now would you? The details of the voltage requirements for your laptop are usually listed on the user manual.

Power supply

In addition, another laptop I found during my research is the Dell Inspiron 1440 power supply. Power supplies are for the most part misunderstood or even ignored. Many will rush to upgrade their SSDs and graphics cards and totally overlook the power supply.

However, if you take some time to think about it, the power supply upgrade will enhance the stability of your system as well as lengthen its reliability. When purchasing this product however, you should consider the following:

  •      The manufacturer
  •      Its output
  •      Form factor
