Can you power a Intel D410PT Mini-ITX board with a battery?
You can power any board with a battery. The battery just needs:
a. Enough power output to run the board and your peripherals. A battery is practically a voltage source, so you can find out it's maximum power output (in Watts) by multiplying it's current rating (in amps) by it's voltage.
b. Enough capacity (we'll use units watt-hours) to run the computer for a useful amount of time. Batteries often have a rating in mAh (milli-amp hours) or Ah (amp-hours), so the capacity in watt-hours is found by just multiplying the amp-hour rating by the voltage. Ah = 1000 * mAh
Now let's get into the specifics:
The Intel D410PT uses a standard 2x12 pin ATX power connector for power. An ATX power connector provides several different DC voltages to the board, so in order for a battery (which only has one output voltage) to power the board, you will need a DC-DC converter specifically made to convert from a single battery voltage to all the right voltages in the ATX spec. Before you start designing a DC-DC converter though, be aware that you can actually buy such a thing ready made. You can find some here -> http://www.mini-box.com/DC-DC, or just google 'DC-DC ATX'. You'll notice these typically only have 20 pins, instead of 24. That's ok, the extra 4 aren't necessary unless you're using a lot of power (ie, using a graphics card in the PCI Express x16 slot might use too much power for the 20 pin connector). And if you're running on a battery, you should be trying to minimize power consumption anyway. So, when you're choosing a DC-DC converter, you need to make sure that your battery voltage matches what the converter can use as an input. For example, many accept only 12V as input. This is the voltage of the electrical system in a car (and, a car battery). You may be able to combine multiple batteries in series/parallel to produce the right voltage and maximum current for a given DC-DC converter. Some converters can work with a variety of input voltages, so that may make it easier to find batteries that will work.
So, to get everything you need to have a battery powered system, here's what you should do:
1. Get an accurate estimate of the amount of power the system will require.
You could do this by setting up the whole system with a regular old plug-in-the-wall atx power supply, and measuring the most power it consumes when you boot it up, using a power monitor such as the Kill A Watt EZ (http://www.amazon.com/dp/B000RGF29Q/?tag=hotoge-20). You could also just estimate by adding up the power consumption ratings of each of your components (cpu, ram), or just google around for clues. Your answer here should be in Watts.
2. Figure out how long you need the system to be able to run on the battery.
Just choose a length of time that works for you (in hours).
3. Determine what capacity the battery (or bank of several batteries) needs in order to run the computer for a while.
Multiply the answer to step 1 by the answer to step 2.
4. Choose a battery, or perhaps several batteries, to meet the requirements of steps 1 and 3.
Keep in mind you can wire batteries in parallel to increase the current they can supply (and therefore the power they can output; power = voltage * current).http://www.instructables.com/id/How-to-Wire-Batteries-in-Series-or-in-Parallel/
5. Choose a DC-DC converter with a power rating at least as high as necessary (from step 1), and that will work with the battery setup from step 4. Or, go back to step 4 and choose different batteries that work with the converter you want.
6. Wire it up! You might be able to find handy battery cases to make it easier, otherwise you'll have to get more creative.
Keep in mind that you'd need to do some fancier work in order to keep track of how much battery life is left at a given time.

You can definitely overdo it, and -20C would probably do that. Most electronics, not just computers have a temperature range, including a minimum and maximum.
What is Random access storage?
Random Access Memory (RAM) is not used for storage. A random access storage device is the hard drive, where data can be stored and accessed randomly. Any data on the volatile RAM is lost when the computer is switched off.
How do you know pci-e or agp or pci?
Find out the make and model of your Motherboard,
Then check on their website to see the specifications of it and see what expansion card slots it has.
On a Dell E4300 laptop what does the button to the left of the power button do?
It is the "Latitude On" button, which is supposed to give you a much quicker start, and much much longer battery life (with many of your same apps) by not loading Vista, but rather loading a version of Linux which is hard coded on your chip. http://en.wikipedia.org/wiki/Latitude_ON Early versions of E4300's (like mine) only have it in a "reader" mode, but upgrades are on their way It seems like an attempt to get the best of both worlds ... the low-power perks driven by UMPCs, and the high power features common on Vista machines. Great idea! by the mobile learning team at www.m-learning.org
Why do keyboards have two ctrl keys?
To be able to reach it with one hand and to program the 2 control keys differently
What is a good PCI video card for gaming?
The Radeon 9800 was the best you could get a couple of years ago, and is still worth checking out now.
Can you upgrade your video card in acer 4736z?
tha acer 4736 does not HAVE a video card. it has an integrated video chipset made by intel, and no, it cannot be replaced.
The Letters Stand For Different Types of signals frequencys essentially. Wireless N is the best and newest. It doesn't interfear with other wireless devices like cellphones,microwaves, and other electronic devices. Wireless N also has alot better penetrating range and coverange area. It also allows for quicker internet access without the interference Wireless G is todays Standard. Alot of devices use this today. Wireless B is the older Standard Only a wireless N Wireless adaptar is compatible with N,G, and B routers. The same cannot be said about Wireless G and B. To get the full potential of N you should have both a wireless N Router, and a Wireless N Adapter in the computer.
How can you reclaim your Facebook fanpage if your personal account was hacked and disabled?
To be frank it is not safe to hire anyone online because you can never tell if they are trustworthy or not, the bulk goes to whether they have been tested and confirmed to be safe. I have been at this junction before of if it is safe to hire a hacker on Quora, I feel quite sad to tell you that a ran into a few fake hackers myself, I never thought I'd be a victim but I was. By the time a friend of mine introduced me to a real hacker, I already gave up on trusting a hacker anyway. But my friend convinced me that trust is the soul of any transaction or business deal, we need to trust people in other to satisfy our needs, it's what business on and off the internet is based on. After I understood what my friend meant, I followed his recommendation and hired the hacker he introduced to me, fortunately for me, I wasn't disappointed at all. The hacker turned out to be a real professional who is very efficient and trustworthy. Although she took a bit longer than she promised, in the end, she showed immense resilience and got the job done. That is why I answered this question to confirm that there are real hackers who are safe to hire, they are rare but they exist. I'm not really into sharing emails on quora but it will be unfair if I can't provide this remarkable hacker's contact… so if you discreetly need the service of a legit hacker then you should be talking to ( Kathrynsturm0617 AT GMail DOT com )she is an Angel and a life saver. Meet her for any hack related issue. Thank me later.

Server System Infrastructure
When you boot the computer there is no beep What is the reason?
Some computers do not make a sound when starting up. If it used to and doesnt now it could be from a recent hardware change/update or from a BIOS/software update. It is not a problem unless your computer wont turn on
What bus port can be used by many different input or output devices?
The Universal Serial Bus or USB port
Used for printers, scanners, headsets, wifi dongles, USB flash drives.......etc
"inverter" has many uses, but here I think you mean a circuit to convert one DC voltage to another by INVERTING the input DC to AC, running thru a transformer, rectifier, regulator to output the new DC voltage. When used in context as an "inverter board" it refers to the backlight of an LCD screen. It is the board(s) that the backlight(s) is mounted on.
