A lot of people still prefer Windows 7 over 8.1 or 10 (including yours truly). I'll upgrade on my own time, I have work to do.

Well none of that is specific to notebooks, most PCs of any configuration from tablets up will have some combination of similar items.

That is the Intel Core i7 processor running at 2.4GHz processor clock rate. The intel website will give you the full details and comparision with the slower i5 and i3 processors.

Core i7 is just the product of Intel processors. If something isn't clear, Google is always there for you. Since the processor isn't clear, try this resource from Intel to learn more about that product of theirs. http://ark.intel.com/products/85214/Intel-Core-i7-5500U-Processor-4M-Cache-up-to-3_00-GHz[^]
Same thing for the Graphics card (yes, that AMD is a graphics card for your machine). What about this link to learn more about it? http://www.amd.com/en-us/products/graphics/notebook/r7-m200[^]
Windows version and the final notebook product item number are a few things that you would be using to find hardware or drivers related to your machine. Windows product is what you can change while purchasing the product. You can select from Windows 7 or Windows 8.1 Pro, your choice.
If you find difficulty in learning something or understanding, always try to Google for it. Google has a good base of search results for you.

Each and every machine that a manufacturer provides has a clear table list for their specifications. I have, as far as I searched, found it very easy to read the specifications for the machine.
The only thing that might make it hard for you to read and learn the specs is the UI and UX of the website. Can you point me to a notebook which doesn't have specs clearly written or explained?

I asked the internet search engines, and came across conflicting experts. (Who'da'thunkit ?)
If we build a card with a video camera which uses a Bluetooth connection back to "home base" so to speak, can we expect a robust and clear video result for the user ?
I'm not clear on how to do the arithmetic.
What times what, divided by what, gives me what result ?
Then of course, I need to consider things like theoretical scientific stuff on the internet -vs- what we're going to experience in real life; but that's a different conversation.

In theory the data should be as good as any other transport mechanism, but only testing can tell you for sure. You do appreciate that Bluetooth is only for very short (<10 metre) distances?

Understood. The existing design ("dream" might be a better word after some recent feedback from my gang at work) will be boxes in the attic. It's all up in the air now.
Might not even happen at all.
Oh well, I thought it was a pretty good idea.

Bluetooth doesn't penetrate walls (and ceilings) very well. I think you'll face a lot of signal quality problems.

Something else to keep in mind are the data rates available in the Bluetooth standards. The rates are pretty low, so you could stream video but you'd have to do a bunch of compression and probably accept the fact that the video won't be all that good. Bluetooth works for audio because the data rates of compressed audio are very low.
See Bluetooth rates here (under "uses"): https://en.wikipedia.org/wiki/Bluetooth[^]
In contrast, WiFi rates are significantly better... so system design question to you might be, you can use Bluetooth, but why would you? What are the benefits from such a system?

Check.
Bluetooth is out for this gig.
The reasons you enumerate are exactly what went through my head.
Obviously, you're a smart guy.

I hope this is the correct forum for such questions..
Is an adapter (the wrapper, that is) really needed in order to put a nano SIM into a micro SIM slot? I tried without one and there doesn't seem any problems. So, my question is, if I continue like this, apart from trivial "non-detection of the SIM card case", what is the worst that could happen? Agreed, those adapters are so cheap to buy, but just wondering...
Thanks in advance.
You have just been Sharapova'd.

You can short the voltage/ground leads that are going to the card. That could potentially mess up your phone since the source that would burn out would be in the phone and not the SIM.

What questions should I ask about surge protection and Uninterrupted Power Supplies ?
What's important ? What's marketing mulch ?
At the moment, I don't really have the vocabulary to know how to read the ads.
What numbers are real stuff, and what numbers are so what ?
Thanks for any education you might care to offer. It'll help a lot.

Just a small hint: You might want to watch out for idle cooler noise if you plan to use it in your office. I once bought one where the description said nothing about it and even in idle it was many times louder than my PC

First of all always look for well known suppliers, that will give you better guarantee.
Then look for a true sinusoidal UPS, which means that the output is sinus shaped resembling the line waveform. The cheaper square-wave devices can create problems to switching power supplies of PC and other electronic devices. For more or less the same reason check the minimum allowed load power factor, this parameters directly deals with current phasing of inductive loads, but for electronic devices lower power factors means that the UPS can tolerate higher waveform distortion and the harmonics generated, again, by switching power supplies of electronic devices.
If you are looking for medium-high power UPS's looking at characteristics you'll find also an harmonic THD distortion, the lower the best.
About surge protection don't worry too much, an UPS device by default give surge protection: A surge is a fast transient overvoltage of power line (up to 200-250% of nominal value), because an UPS output is controlled and regulated you should be theoretically free from them.
Another important characteristic is the autonomy: how many minutes of power it can deliver at nominal power. This defines the dimensions of the battery pack. Choose the right time you need, the batteries are very expensive and are also delicate. Remember that batteries have a lifespan (that depends very much on ambient temperature, higher the temperature shorter the life), good quality batteries will guarantee a life of 18-24 months at 25°C +/-2°C.

Hi All,
I have always used VMWare on my laptop for studying purposes. The laptop runs an i5, 6GB RAM and standard HDD. It has performed pretty well overall for running 1-2 servers and a client over the last few years, but as you can imagine, it's at its limits!
I have picked out a new machine running an i7-4790, 32GB RAM, 256GB SSD with a 2TB HDD. It will be running Windows 8.1 Pro and as far as I can tell, the OS and spec support all the requirements to run Hyper-V.
I am aware there are only 8 threads on the i7, but this machine is only for study purposes so the machines won't be running anything too heavy and only running perhaps 3-4 VM's at once. How will the machine stack up? I know it will be a massive improvement in comparison to what I have now, but I don't want to spend out and then find there is a bottleneck holding me back!
Thanks

Is there any way to test a PC power supply under load without hooking it up to actual PC parts?
I have a power supply tester that shows the voltages coming out of the supply, but it does not place an actual load on the supply.

...the impossible takes slightly longer.

PC power supplies require a minimal load to source output voltages inside the specification range. Some will check if a load is connected and switch off outputs with no load. So each of the 3.3, 5, and 12 V rails should be connected to some kind of load.
For the 5 and 12 V rails I would use an old drive (floppy, CD/DVD, or hard disk). The 3.3 V rail can be connected to a load resistor (e.g. 3.3 Ohm, 5 Watt). Finally you must connect the Power On signal (Pin 16/14 for ATX-24/-20) to GND.
It might be necessary to connect an additional load resistor to the 12 V rail because the load may be not enough when the motor of a conncted drive is not running.
Additional information can be found at the Wikipedia[^] page (see also the links at the bottom).

You will need voltage meter for this.

My mouse clicks are disappearing.
i.e., I click, and sometimes the machine (or website) responds as expected, sometimes there is no response.
Concurrent observation: My keystrokes are frequently delayed.
i.e., what I type appears on the screen, but delayed.
Other concurrent observation: Some of the mouse clicks are delayed, while others just don't occur.
Who's the most likely culprit ?
Worn out mouse ?
Driver in Windows ?
-- OS --
Win'7

It has a bright red LED on the bottom side to do the tracking.

Take a look at perfmon.exe (run it as an admin), and find out if some processes use up a non-adequate amount of resources (processor, harddisk, memory).

Run pc in safe mode if working well there then it's driver problem.
