Q:my portable HD has 2 USB cables, one for the computer and one for power... why?

In order to work they must be connected to your computer, and to a power source. Would your car run if the engine were not connected to it?

Q:Things to think about: -valley has steep sides -the slopes are rain forest or small villages -no roads built in the area -the cable towers are 5000 ft apart at some points, but others only 3000 ft -the towers are 15000 ft above the floor, others only 500 ft*activities must not create significant noise*Cables are not allowed to sag below 120 its for my technical report for civil engineering technology....any ideas will help even the craziest ones..thankss soo much

That's a long span, but not impossible. You might want to check out the Ameralik span in Greenland for some ideas (it is about 3 times that long, at 5376 meters) Here's one reference:

Q:The Leader of the band inists that all power cables connected to the amplifires be placed away from the performance area.

To prevent injury to performers and to protect equipment from potential shorts and for fire safety.

Q:So I finally bought a quot;boss blues driverand when I got it, I assumed it didn't work, because it didn't turn on, I tried it with an adapter and still nothing. So I decided to take back to the store, the guy who helped me plugged in with a power cable and used a battery, and it worked. MY QUESTION IS; do you need both for it to work? Or is there another option, for just the power cable?

I have the blues driver and it is my favorite pedal you need one or the other you have too make sure its hooked up right the out put goes in the amp and the input goes in the guitar

Q:What happen's when you just yank the power cord out from the electronic (Computer or TV) while it is still running? Does it blow a fuse or something? And what should I do to fix whatever the problem is, assumming that the electronic doesn't turn on after i yank the power cord out?

Electronic devices should be OK if the cord is yanked, as long as it isn't done too often. It would be just like a power outage, the device would turn off immediately. It shouldn't blow a fuse or anything like that. If you pull the plug and it doesn't turn back on later, it could be that the power supply or transformer has gone bad. These are easier to replace in computers than in TVs and often cost less than $50.

Q:I got two hard drives. The cable connecting the hard drive has 2 connectors, does it matter which connector goes to the master drive and which goes to the slave drive? same question regarding the power supply. 2 connectors on the power cable, the order matters?

The power supply cable doesn't matter. The master HD is on the second, end, connector.

Q:HelloWhen i turn on my computer without 4 pin ATX +12 volt power cable my computer starts and everything goes fine but when i connect it to my motherboard my computer does not start.i want to know that is this cables necessary for normal computer operation or i can go without it??I am using ATX 20+4 pin main power cable for my motherboard power.

The 4-pin 12V ATX connector (yellow and black wires) supplies voltage to the Voltage Regulator MOSFETS that power the processor. If not connected, processor does not power up at all. If it is connected and PC does not start, power supply is sensing an overload/short on the VRM circuit, thus enabling PSU overload protection to protect PSU and motherboard as well. I am suspecting that either motherboard (at VRM portion) is grounded to PC case or the cooler is touching a circuit of the VRM. Try remounting motherboard and/or cooler.

Q:Hi,I recently bought a daewoo l700c monitor second hand.Its cheap because It didn't come with a power supply/power cable.I know that It requires one of those one point plugs..like the ones that go into some laptops.Help please?

Q:as far as i know, the only cable that connects the hdd with my motherboard is the sata cable, is this the cable that will do both transfer data and also provide electricty? or do i need another cable to connect the hdd and to power supply? same for my sata dvd burner, thx!

That all depends upon the present cable and the slots to which it is connected to.

Q:I managed to break off the tip of my laptop power cable to the point that I need it replaced. I can't pay with cash on OKorder and don't own a credit card. Anyone know an electronics store where I could find another? Thank you.

Eee mini laptops use something referred to as an SSD complicated force or a stable State force. those are drives that have no shifting factors in them. THey perform very such as a USB flash force with in uncomplicated terms circuits and chips on them, no automobiles, no platters, no needles like complicated Drives. they are very rapid and extremely cool to assert the least :) With admire to those with cameras they are the fashions in the 900 and 1000 sequence that characteristic cameras. The seven hundred sequence ones have an non-compulsory digital camera on the 701 sort. have exciting at the same time with your new pc mini :) they are exciting Oh and additionally look at IBM, they make mini laptops too and additionally the recent MacBook Air is a mini pc, it extremely is particularly easy, slender and probable the best one :)
