10 things to consider before buying a computer
We spend a lot of money to buy our hobby computer.Keeping in mind a few things, your computer will be much better
1.Size
If portability is your main concern, then you need to consider a notebook that has a small-ish screen and a light weight. Any laptop marketed as an Ultrabook should fit your bill here, as they are designed to be slim and light. More to the point, though, look for a laptop with a screen that’s 12.5-13.3 inches in size, and a weight that is from 1-1.5kg.
2.Screen quality
You’ll be staring at your laptop for many hours every day, so you want to make sure you get a screen that is comfortable to look at. Many laptops these days also have touchscreens, which means they are glossy. Glossy screens lead to reflections, so consider a laptop that doesn’t have a touchscreen.

Next, look at the resolution. A 1920x1080-pixel resolution (aka Full HD) should be considered if you want plenty of space to line up windows and keep things in view. Finally, the viewing angles are extremely important. A laptop screen that touts IPS (in-plane switching) technology offers the widest viewing angles and the best user comfort.
Try not to buy blind. If possible, go into a store and see the screen for yourself. Otherwise, rely on multiple reviews to get a good overview of the product.
3.Keyboard quality

What's the difference between an Intel Core i3, i5 and i7?
For long typing sessions, you must get a laptop that has a comfortable keyboard. You don’t want to get a keyboard that packs in every key under the sun (think keyboards that have squished in number pads) because that can translate to a poor overall user experience when hunting for keys like the arrows.
You want a keyboard that has a comfortable layout with full-sized keys and some space around the arrow keys. The keys should have adequate travel on the downstroke and snappy responsiveness when you let them go. Make sure the keyboard is also backlit, so that you can type with an easier view on the keys in dimly lit environments.
As with the screen, it helps to try before you buy, especially if your main task will be typing.
4. CPU
READ MORE
It’s hard to go past any of Intel’s Core-based CPUs when buying a new laptop. Think Core i3, Core i5, and Core i7. These CPUs offer the best performance when it comes to multitasking and multimedia tasks. Core i3-based notebooks are generally found in entry-level systems, while Core i5 makes up the majority of mainstream computers.
Core i7-based systems are for those of you who want the best performance from your laptop. However, note that with a Core i7-based system, heat coming through the base of the laptop can be cause for concern, especially if you plan to actually use the laptop on your lap a lot of the time.
5. RAM
You need 4GB of RAM or more to get the best out of your system. More RAM allows for more applications to be run at the same time, and for more data to be quickly accessible by the system at any one time, which comes in handy for tasks such as editing photos.
6. Storage
Hard drives used to be all the rage, but these days they are mostly out of favour, especially for thin and light laptops. This is because they can be slow, somewhat bulky, and produce noticeable heat and noise. A solid state drive (SSD), on the other hand, offers a lot more speed than a hard drive, runs silently, and can be installed in a form factor that doesn’t add too much to the weight and bulk of a laptop.
7. Battery life
Manufacturer-quoted battery life is often not indicative of what a laptop can do, and this is based on the many variables that affect battery life. These are the screen brightness, the screen resolution, and the tasks that you run. If you run programs that need lots of processing, or if you stream lots of online video, or if you transfer lots of files over your wireless network, then your battery will drain a lot sooner than what the vendor has quoted.
8. USB 3.0
You shouldn’t get a laptop without a USB 3.0 port, and you should look for a laptop that has at least a couple of these ports. This is for obvious reasons such as plugging in an external hard drive to back up your laptop’s data, or for when you want to plug in a conventional mouse or a fancy keyboard.
9. Fingerprint reader and TPM
Fingerprint readers are great for logging into mobile devices and the latest Windows 10 Operating System makes further use of them with its Windows Hello system. Ultimately, people can guess your password, but few can fake a fingerprint.
10. Build quality
No matter how careful we are, laptops can get bashed and dropped. Some are ruggedised to withstand rain and dust and some are built especially for the brutal educational environments - some even come with military-grade protection. Others can weather liquid spills and can be rinsed clean. Either way, it's worth checking out how much testing a laptop has undergone (the manufacturer usually crows about it) or whether there's any certification.
