Summary
Questions on specifications of laptop that will be used for study and (later) research
Father was thinking about buying a laptop that I can utilise for my studies. Our PC (windows 7 pro, 32 bit) is proving incapable for much of the software that I would like to have. Being 32-bit, I cannot install latest java and Matlab on it. In addition, if you have a look at this thread (mainly the later posts), you will understand what problems I am facing while installing MikTex.

Keeping these in mind, I would like to ask about the specifications for the laptop. As I said, this laptop would be configured for study purposes, especially research (no gaming).

First, what softwares are essential for any research scientist (irrespective of field)? Some trivial ones are below:
1. Java (very trivial, but worth mentioning)
2. Matlab (or some similar math software)
3. LaTeX editor and compiling systems
Can you suggest anything else (paid/free) that could be necessary?

Based on the above, what should be the minimum requirements of the laptop? By this, I mean:
1. RAM
2. OS
3. Hard disk size
4. Battery
Anything else? Should I consider an inbuilt disc drive, or should I later buy an external RW drive?

For OS, I am choosing Windows (actually I have to, as I am not familiar with Linux or Mac). Perhaps windows 10, 64-bit. Which version, professional or ultimate?

Also, I don't want to buy any third party antivirus. My experience with QuickHeal is already bitter. Dad was saying that Windows has its own antivirus, and it doesn't create problems like the third party software is creating. Is that good and can be trusted? Does it come free with windows?

Thank you for reading, and would appreciate your suggestions/opinions.

Since you're planning to run Windows, it would be useful to have MSFT Office, which includes Word, Excel, PowerPoint, and several other applications. You can also opt for Libre Office, which is open-source and free.
For myself, I would also want MSFT Visual Studio, which is pricey unless you get the Community Edition, which is free. I've been fortunate enough to get free copies of Visual Studio up through VS 2017, as I have taught at colleges that have licenses for free downloads of the software for students and instructors. I would also get Python, which can be downloaded for free from python.org.

I'm thinking about getting a laptop for myself, but this wouldn't be my main computer -- just something I could take with me to the programming classes I teach. The desktop computers I own are an HP Pavilion I bought in 2013, running Win 7, and a Dell Precision that I bought last fall, running Win 10, with a 10-core processor. I'm very happy with the Dell, but I've heard enough bad things about Dell laptops, that I'm leaning toward a Lenovo Thinkpad for something to buy.

I did a search for Lenovo Thinkpad laptops, and came up with a site that offers an X1 Extreme model starting at $1389 (USD). The specs say up to 8th Gen Intel Core i7, up to 64 GB DDR4 RAM, up to 1 TB SSD hard drive, and NVIDIA GeForce GTX 1050 TI GPU with 4 GB RAM. I'm sure if you choose the high ends of the "up to" options, the price will go up significantly from what I quoted. My thought when buying a computer is that the more you spend up front extends the date at which the computer becomes completely obsolete. My HP is now six years old, but runs everything I want it to run, and I've never had any problems with it whatsoever. I do need to upgrade the OS soon though, as support for Win 7 will be running out soon.

I would personally go for Pro, as it's likely to be a lot cheaper. I don't know enough about the two versions to give any other reasons than that.

My Dell Win 10 computer has Windows Defender as part of Windows, and from what I've read, this is pretty good AV software. A very useful addition that I haven't added to that computer is Malwarebytes anti-malware software. (I have a paid subscription on my older computer, and will do the same on my newer computer one of these days.)

If your only problem is that you need a 64-bit OS, why not just install it on your present laptop?

At present, we don't have a laptop, it's our old and faithful pc. But we need a backup option. In addition, if I have to stay away from home for studies, I will need a laptop. So a simple upgrade of the pc might not be helpful.

Actually I didn't mention that, thinking it would be too trivial. Any windows computer almost always has MS office.

True. The price that you mentioned is already above the budget. Actually this is something that I have kept in mind too:
My thought when buying a computer is that the more you spend up front extends the date at which the computer becomes completely obsolete.
It would not be good if I buy a laptop, and within one year I find that it is not catching up with my needs. That's why I posted here, such that the laptop can be at least used till phd.

Maybe 64GB ram would be too much. Perhaps 8GB or 16GB would be good enough for now.
My Dell Win 10 computer has Windows Defender as part of Windows, and from what I've read, this is pretty good AV software. A very useful addition that I haven't added to that computer is Malwarebytes anti-malware software.

I know about Malwarebytes, but if Windows Defender works, maybe I'll not purchase anything else now. You see, I would basically be using this pc for studies. No Facebook, no twitter, maybe PF. So I hope that there will not be much of malware/virus problem.

Not necessarily. You can order it as an additional option when you get the computer, but if you do, it's an extra charge.

From what I've read, the two work better than just Win Defender alone.

I suggest that you might try doing a little hunting on ebay. You can find a good 15.6" quad-core I7 machine with Win 10 pro and 8GB RAM or or better for under $500. Here's an example of better-than-average for $600. For sellers with a high number of transactions, I look for a 99%+ positive feedback rating -- sometimes I'll take a chance on a seller with a low number of transactions but a 99.9% or 100% positive feedback rating.

I advise that you shouldn't feel too wedded to Windows, just because of it being the adversary you already know. You could, for example, check out how your current machine performs on Scientific Linux. You can download the Live CD image, burn it to a CD, boot from it, and then 'just jump in'. It wouldn't take you long to be comfortable with watching streaming video using VLC media player, or surfing the net with Firefox, on the SL platform.

That would allow you, for example, to buy a very good pre-owned/used machine that has had its HDD (often for privacy reasons) removed, for a much lower price than it originally sold for, into which you could add, say, a 1TB SSD, for around $100 or less.

microcenter has refurbished deals


I bought two refurbished desktops/workstations for less than $350 USD each, both are i-5 with a reasonable amount so RAM, the only thing I waswn't happy about was they only had a 500G hard-drive. I looked thru the p laptops, they are pretty reasonable price/spec-wise.

In my view, Micro Center is pretty good; however, at least most of the time, part of what you're paying for when you buy from them is their warranty, and they don't commit to anything substantial regarding what is meant by 'refurbished', beyond that it will be functional as described, and you can get an assurance as good as that when you buy from a good seller on Ebay and use PayPal to pay, instead of probably paying a significantly higher price to Micro Center than you would be likely to pay for something similar on ebay.

I know that Windows is not the preferred OS for most people. But given my state, I would also consider whether I would get help and support for the OS. For Windows, as you know, a simple google search will give you answers to most of the problems. If I have to post in a forum or mail someone for every trifle, I would rather not choose that OS at the moment. But I would keep SL in mind. Maybe after a few years when Win 10 is obsolete, I will upgrade to SL rather than to another version of Windows.

One very nice set of things about Scientific Linux is that it's carefully vetted by Fermilab.
I know that, but there is little official support from Fermilab:
Please contact your support organization for their support offerings.

Fermilab does not offer official support to the general public. Fermilab users should contact the Service Desk.

The Scientific Linux community may volunteer to assist with some issues at their discretion.
It is not that I will get official support for windows, but apparently a lot more help material exists for Windows.

But I have not ruled out SL. As you have said, let me try using it on my PC. If I find it difficult, maybe I will install both Windows and SL in the laptop.

I have SL, Win 7, Win 10, and 2 other operating systems bootable from one of my HDDs on one of my PCs. In my opinion, SL is easier to install as a secondary OS beside an already existing OS than Windows is; SL doesn't arrogate to itself the idea that it's the 'onliest' as much as Windows does. Regarding the support issue: well, SL is based on RedHat, and there's plenty of support available from the nice guys over there, even if you're a white-labcoat-wearing Fermilab groupie.

Anyone has any other software that is worth mentioning here? I'll be buying the laptop soon.

We are thinking of buying Intel i7. Can anyone throw light on the efficiency and cost of octacore vs quadcore processors?

Also, to support external GPU in future, what do I need to look for in my laptop? Do these external GPUs connect via USB (type C), or do they require some other port that I must search for before buying the laptop?

By the way, we are thinking of a 1GB (internal) graphics card.
