Things to consider before heading out and buying a notebook

My mother needs a notebook, and I promised to get her one for Christmas. Since this is her first mobile computer -- she only used desktop PCs until now -- I had to make sure that I have covered all the bases before I made a buying decision.

This guide looks at the things that I needed to know, and others that I could decide on my own.

I made the decision to take her to a nearby electronics store to test some of the devices there, as it is usually better to see something with your own eyes than having it described to you only.

The list below is divided into two parts: first usability related features, and second technical features. I'm not including the look and feel in this guide.

Please also note that I'm not making a lot of suggestions here either way. I'm not favoring a particular brand over the other, a cpu that you should get, or anything else.

What you find below are things that you need to be certain about before you buy a laptop. Some may be obvious, others not so much.

A resource guide is available after both sections that you can use to read reviews, look up and compare models, and make educated decisions.

My suggestion would be to write down what you want to do with the device first, and then go through the list below to pinpoint what you really need.

Usability

There are lots of things to consider in this regard, and I'd like to address the most important ones only here:

1. Screen size

Laptops come in many different screen sizes, from 10" to 18" and even less or more if you look long enough. Screen size is important for a variety of reasons. First, you need to be able to read properly what is going on. If you select a size that is too small, you may run into issues or slow yourself down because things are not as readable as they should be.

If you pick a larger screen size, you automatically increase the weight of the device and may also impact its battery life.

2. Keyboard

Depending on how you work with the computer, you may want a full qwerty keyboard with numeric pad, or a smaller keyboard instead where select keys are missing.

Smaller devices have smaller keyboards usually, which often means that the keys that they offer are smaller as well.

It boils down to how you use a computer. If you ignore the numeric keypad and the arrow keys for the most part, then there is nothing wrong with picking a smaller sized keyboard.

3. Weight

Weight can make a big difference. Do you want to chuck 3.5 kilograms of laptop around with you while you are on holiday or on a business trip, or do you prefer the lighter variants that are below the 2 kilogram mark?

A difference of 1 or 2 kilograms does not look like much, but it can make a big difference throughout the day.

Technical details

This includes what features you want the notebook to have and the components that power it.

1. Optical drives

Do you need an optical drive? My mother wants one to play DVD movies and music CDs. Most ultrabooks don't come with one, and while it is possible to buy an external drive, it is not really suitable for mobility.

2. Processor and video card

Depending on what you want to do with the device, you may need a powerful process and video card, only a powerful processor, or neither.

While it is always great to have a powerful CPU on board, it may not make such a big difference if all you do is check emails, browse the Internet, and write documents.

If you want to view HD contents, or run a game or two on the device, then you may want to consider getting a better processor and a more powerful video card for those purposes.

So, if you can pick a laptop with an Intel Haswell cpu, that is a good thing as it improves a lot of things including the devices battery live.

If you are into gaming, you should pick up a notebook with an Nvidia or AMD graphics card, e.g. a NVIDIA Geforce GTX 780M.

3. Storage and RAM

One cannot have enough memory. The lower limit should be 4 Gigabytes of RAM, which should be enough for most cases. If you game, or do a lot of real-time editing, you may want to add more RAM to the notebook if possible.

Storage is usually available in abundance. Depending on what you want to do, you may want at least 500 Gigabytes of hard drive storage, especially if you plan to play high-end games or like to have large collections of videos, photos or other media on the device.

If you do not, you may fare better with a fast 128 GB or 256 GB Solid State Drive.

4. Touch

Many notebooks, especially those with Windows 8, ship with a touch screen. It adds another control option to the device. Instead of using the keyboard or mouse, you can now use fingers to control what is going on.

While that may sound like a nice idea, it depends on how you work with the notebook on how practical that is.

5. Other components

You may have other requirements that are important to you. Maybe you want Bluetooth 4.0 support, a microphone jack, support for a docking station or a detachable screen.

6. Ports

What do you want to connect your computer up to? E.g., Do you do presentations that require connecting your computer to a projector with a VGA connection? Do you want to link your computer to an HDMI connection on your TV? Yes, there are adapters for such things, but it's always nice not to have to fool with them.

7. Screen resolutions

Screen resolution is no longer tied to the screen size like it was in earlier days. You can now get small sized devices that offer a high screen resolution.

The bare minimum that I'd go for is 1024x768, but if you can get more, take it.

Resources

While there are sites out there that review certain laptops, I have found two retail sites to be really good for getting opinions on select models.

1. Amazon

Amazon is the obvious choice. While the laptops there may not always be the cheapest, popular ones get a lot of user reviews. My suggestion would be to read those reviews, especially the good and bad ones, to get a solid understanding of a device's advantages and disadvantages.

You may find devices here with thousands of reviews that can help you tremendously in your decision making process.

 2. Newegg

Newegg is a popular shop, and while the comment counts on the site may not come close to those on Amazon, they may provide you with reviews that are often more technical in nature.

Plus, the site is a lot easier to navigate as you can use the sidebar to narrow down the listing.

3. Test Freaks

The website accumulates reviews from other sites. This makes it ideal for research, as you find out how it was rated on Amazon, CNET, Best Buy, and other sites. It is a price comparison engine as well, so that you can check out the cheapest offers on the site.

While I would do some research of my own on this before I make a buying decision, it can provide you with a good baseline for that.

Closing Words

    Is “Catalyst the user panel”, the device drivers, or the combination?

    I have a Celeron motherboard with twin Radeon 9250’s on board, and it’s fine for nearly everything, but has terrible difficulty playing videos, even from the hard drive. I installed the latest “Catalyst” (10-10_xp32_dd_ccc_enu.exe) and the device drivers still say they are from 2006. This may be the best there is for this board, but it’s sure hard to tell.

      Nope. The instructions didn’t ask me to. I suppose it will just use a vanilla Microsoft driver if I do that? And actually boot? So then I can re-run the Catalyst install?

        It is probably best to clean all old drivers first and reboot the machine afterwards. Windows usually offers generic drivers. Once the system boots install the ATI Catalyst drivers again to see if it makes a difference.

    “gives any application access to the Graphics Processing Unit for non-graphical computing” means it’s basically the ATI/AMD version of NVidia’s CUDA which allows the GPU’s processing power to be used for other stuff than graphics, eg. for physics calculations (through PhysX in that case). That can lessen the load on the computer’s CPU

    Just adding my 2 pennies, I think the APP drivers helps GPU intensive apps run concurrently without crashing. I have an ATI 5870, the usually (non-APP) 10.11 ATI driver crashes (after a few seconds) when I run a 3d game (CoD Black ops in windowed mode) along with running a flash based (TV stream) on firefox. Symptoms are: Game hangs momentary (which I then am forced to close), flash player crashes and ATI driver recovers from a crash.

    With the APP drivers installed, this concurrent usage of my GPU seem to run both apps smoothly without crashing. Thanks ATI for the new APP drivers. Things work better now. (Mind you I have not exhaustively tested this! Just a
    over an hour of game play while streaming TV). Things use to crash within a few minutes of running the two apps together.

      Thanks for your 2¢. i was wondering abt this and I also have the same gpu and stream on my big screen through it while some other gpu intensive thing on the other. I have noticed , though when i play a bd movie in PowerDVD10 ultra player now my gpu shows zero use through out the whole movie. not sure if it is connected and cyberlink corp can not respond to this adequately at all. so far they dont know what i am saying. I use afterburner 2.0 and have the graph showing gpu use and fps and it works . non blu ray dvd show action and appropriate fps60 or 24 depending how i have it set. so it works. i usually use my stand alone blu ray player but i sometimes just keep the one in my computer active and check to see if things are correct and since adding the APP drivers i notice this anomaly, if it is unusual. i would have thought the gpu would be more active for blu ray play back, no more since adding APP but getting 0fps and 0% activity for the whole movie does not seem right. no comments from amd or cyberlinnk so far

    I made the mistake of accepting HP ink subscription package for some months, then I unsuscribed it. A guy told me that so doing HP had remotely changed my all-in-one printer firmware forcing me to use only original ink cartridges.
    Is there any way to revert the firmware to the original one, allowing me to use generic ink cartridges?
    Thank you.

    There seems to be a mix-up : comments relate to another, older article.

    “Launching the subscription-based service HP+, which, as a feature, blocks using third-party ink for the lifetime of the printer, even when customers unsubscribe later on.”

    This is outrageous — just like the rest. I’ll make a good note never to buy HP. Nor ink-jet printers, incidentally. Laser is the way to go.

    Its remarkable how much Printer makers can get away with it. Its as if this is the first time such companies have been caught doing anti-consumer things.

    – Cartridges having very little ink in them on a small sponge.
    – Printers flagging falsely flagging printers for repairs for no reason whilst locking out users.
    – Printers locking out cheaper third party ink.
    – Placing stickers over the USB ports claiming there is none to force people to use ethernet or wifi so the companies can push these so called updates to disable and control your printers.
    – Disabling unrelated parts of your all in one printer.
    – Forced subscriptions.
    – Time bombed hardware.
    – Overly expensive ink.
    – Falsely claiming ink cartridges are empty when they are not.

    The list goes on and on really and yet nobody has done anything about it. Where is Europe on this? Where are the morons that glue themselves to the roads on this or the league against straws.

    There is just no oversight for this reckless industry. They have been getting away with murder for years.
    I’ve seen some people say that it is cheaper to buy a new printer when the included ink cartridges run out and throw the one they have in the trash which says a lot doesn’t it.

    HP is pretty much a known scumbag in the industry but they aren’t the only one, they all do it to one extent or another.

    Being an “old fart”, maybe it is easier for me than others, but I find myself choosing older items over this kind of HP crap. Yesterday’s Caddilac is much more dependable, safer and cheaper to operate than the modern day Tesla.

      It’s been going for far over a week now. The fact this Comments section is neither fixed nor simply and honestly removed is perhaps relevant of the owner’s plan to let it slowly but surely become obsolete, check if the number of visitors falls as well and if not then remove ‘Comments’ for good, maybe by January 2024.

      I’ve spent many splendid years reading comments, replying, commenting myself here, especially when Ghacks was independent. Comments are so complimentary of articles. End of an era as it seems.

        I feeling so too.
        “M&A” is used regularly by Microsoft as a means of “ruling out rivals”, and Softonic’s acquisition of ghacks.net seems to be no exception. It is very disappointing.
        As is clear from the case of Elon Musk, who acquired Twitter, there are things like locking and deleting comments, authentication systems, etc.
        The future of ghacks is uncertain, and it looks like it will end in tragedy.

        Advances in digital technology are exposing a chaotic and irresistible oppressive reality. Far from being “bright and happy,” the future feels “dark and gloomy” with despair.

I can’t barely remember when was my first comment, however I think that I have been here since 2018 if my memory doesn’t fail. Anyway, there have been so many years reading good articles and also reading some good comments by some good users. Now I am starting with my first job as forestal engineer at long extension areas of Spain so I will have very reduced time to read and comment, however I will continue visiting this site to remember the good times.

        the fixed Martin mentioned is that “From future posts, the association with the article will be properly established.”?

        However, is it impossible to fix the association of comments for a large number of articles that occurred during this period (8/15-9/7)?

        If ghacks.net were to leave these messed up associations in their articles, Subscribers who don’t know about these things will be very confused when they see the article.

        And one more thing, what about the disappeared (erased) Comments?

        If all of them have been corrected successfully, it can be said that problem have been “fixed”.

        Regarding the Comment block and the missing Comments, I feel that there is a need for a clear official statement (by Softonic) on paper for ghacks.net subscribers.

      By the way, if you use an RSS reader, you can track exactly where your comments are (I’m an iPad user, so I use “Feedly Classic”, but for Windows I prefer the desktop app “RSS Guard”).

    @Martin Brinkmann,

    Regarding my comments (#comment-4573235, #comment-4573237) before and after the reply to @Tom Hawack (#comment-4573236),
    I posted it around 2:30pm (daytime) German time, but why is it still not showing up even after almost half a day?
