But it's important to
consider the options you have available to buy a laptop for run your bussiness. You can purchase new, used or refurbished or even lease a laptop. Ok This is what you should look out for when buying a laptop.
Decide on a budget and look for laptops within that budget. Remember! you can get high-end laptops (with high configurations nad performance) but at lower prices simply because the brand does not command a premium price. It does make sense to explore these laptops if the after-sales service is good.
RAM is vital to system performance, lots of RAM you have lets you run more applications simultaneously. This is especially true in notebooks, because notebook graphics processors frequently have little or no memory of their own and share the main system RAM.
Adding RAM is an easy way to boost performance, but first make sure the notebook's memory sockets are accessible. (They're usually under a panel on the bottom of the system.) An easy way to determine how much RAM you need:
1GB: Good for basic office apps, running one at a time.
1.5GB: Sufficient for running several programs at once, photo editing, and basic 3D gaming.
2GB or more: Recommended for high-performance 3D gaming, demanding graphics work, and video editing.
3.Research Your Desired Laptop
Use the Internet to research your desired laptop, read the user reviews, expert comments about it etc. Better to know exactly what components it has (hard drives, optical drive, processor, and video card) and know what software is already preloaded. Be careful of salesman who will try to charge you extra fee just for configuring or installing programs on it, because these programs may already be preloaded at the factory bundle.
It's Depending on the type of bussiness or work you run, make sure your screen fits the job. Graphics and spreadsheet tasks call for larger (wider) screens while e-mail requires very little space.
The minimum you will require is a 12-inch display. High-end users (who want to have the convenience of a wider screen and larger keyboard, similar to their PC) should go for a 15- to 17-inch screen.
You will at least need an Ethernet LAN connection and integrated wireless (preferably 802.11a/b/g - Wi-Fi) card. Also check for Bluetooth connectivity - it will enable you to wirelessly transfer data to other devices for up to 30 feet.
Your laptop Batteries should work forever, your laptop need good power to work properly. For basic laptops, a single Lithium-ion primary battery should at least last 2 years.
That's it, just simpliest tips you should consider before buy Laptop. And last, but not the least, read your warranty information carefully before you make a purchase.
