What students need to know when buying a laptop

Laptops are for sale everywhere – but choosing the one for you isn’t easy

Buying a laptop (or a notebook, as some call it) isn’t easy.


Doing so requires determining what your needs actually are because, without that, laptop specs can be a confusing array of numbers that don’t truly paint a proper picture.


Is speed more important to you than hard drive space? Are graphics more integral than the built-in speakers? Is a smaller screen more important than having a CD/DVD/Blu-ray optical drive?


There are low price ACER AS07B31 Battery, ACER AS07B61 Battery with high quality at our australia acer battery online shop.


These questions matter because finding the happy medium isn’t easy, and you almost have to project what it is you will need later on. You want to be able to hammer out papers and essays, but also have the flexibility to edit photos and watch limitless amounts of video.


Unlike desktop computers, laptops have little room for upgrades and tweaks, but that doesn’t mean there isn’t room for improvement. It may surprise you to know that you actually have more leeway in telling the manufacturer what kind of a laptop you actually want. This goes for Macs, too, as Apple offers build-to-order options for its laptops as well. These types of orders are typically done online, where you can choose to upgrade specific components.


This is rarely an option with brick-and-mortar retailers who agree to sell particular specs for the computers they carry. But there is a difference when ordering a laptop through the manufacturers’ websites. So, for example, if you were very happy with all the specs of one particular laptop, but preferred to have more RAM and hard drive space, that can be done, albeit for a bit more money.


We also provide brand new ACER AS09D70 Battery, ACER AS07B41 Battery, ACER AS07A31 Battery with 1 year warranty.


Rather than focus on specific laptops on sale now, we’ve instead focused on what the specs actually mean.


Processors — The lifeblood of a laptop, the processor determines how fast applications and tasks run. If you’re looking to run several apps at once, an Intel Core processor is a much better option than the Atom ones used in netbooks, for example.


RAM — RAM is installed memory, so the more you have, the more apps and tasks you can run simultaneously. Having just 2GB of RAM may be fine for minimal needs, but you’re better off starting with 4GB if you need to multitask more. The good news is that RAM is one of the easiest specs to upgrade.




Hard drive — This is an easy one, because it all depends on how much data and content you feel you need to store on your laptop. If it’s going to be your entertainment hub, then you might want to get more to be on the safe side.


Screen size and weight — The bigger the screen size, the greater the weight of the laptop. For example, it’s hard to find a 15-inch laptop that weighs less than five pounds. It also depends on if you want a glossy or matte screen.


Laptop Battery life — Never trust the number you see on a spec list. Battery life is so relative that the number quoted is not based on actual usage patterns. So, if you see “seven hours”, the more likely number is five.
