- Q: Hi, my old laptop has broken: when i try to put the power cable into the socket on the laptop, it only goes in on a certain angle and never stays there even when taped, so its impossible to get the laptop on for more than a few seconds. I've tried different power cables too, and nothing seems to work, so it must be the actual laptop problem... how can I get the laptop to stay on to retrieve some photos that I have got on there? Thanks
- I would remove the hard drive.Take the hard drive and your new computer to an electronics store and buy a USB crossover adapter plug. That should allow you to hook the old hard drive to your new computer. It would be like have an external hard drive. I did it a few years ago. I was told recently that the newer computers are not compatable that way. Also, if you have different operating systems the new computer may not be able to read the old hard drive. The other option is to have the power supply socket repaired. Some small independant repair shops can fix the problem relatively easy and cheap.
- Q: im upgrading amps from 200 to 1000 and i was wondering if the cables will restrict the current at all? right now i have a 225 watt cord set
- 200 to 1000 (if you have that much power) from 20hz to 20,000hz i would sugest a dedicated line .strictly for your home theatre gear,with a good power conditioner- with some good power cords,as well as speaker cables. also on the current issue the longer the runs of speaker cables the more current you will lose ,
- Q: Why cross bonding in power cable?
- If so, the answer is: By tying multiple cables together, the current carrying capacity of the total cable is increased without having the total cost increase in proportion. In other words -- using the picture as an example -- tying 4 equal sized cables together increases the current carrying capacity by a factor of 4, but the cost of this multiple-wire cable is less than the cost of a larger single cable that would carry an equal amount of current. .
- Q: THE PROBLEM IS THE POWER CABLES HAVE 20 PINS AND THE ENTRANCE OF THE MOTHERBOARD HAS 22! SO HOW DO I HAVE TO CONNECT IT?
- If it already befell and that's broken, i don't be attentive to of an difficulty-free thank you to repair it. in the adventure that your attempting to be arranged so it won't smash if there's a power fluctuation, get a UPS (no longer the transport service, a battery backup element). in case you do no longer % to spend the money for one in each of those, a minimum of get a surge protector. the united stateswill shop the computing device working frequently for an exceedingly jiffy durring a power outage or surge to furnish you time to shop stuff and turn it off right. A surge protector will in basic terms decrease power to the equipment if there's a surge, so which you get no danger to shop issues or close it down right, even though it is going to shop it interior the case of a power fluctuation. EDIT: I in basic terms found out that that's interior the appliance section. there is probable no application to shop the computing device interior the case of a surge or to repair it afterwards.
- Q: I was replacing the hard drive of my desktop computer but now I don't know where the cable [see picture] fits. it obviously goes somewhere since the computer does not turn on now. The Hard Drive is SATA if relevant. Thank you!
- That's the main power connector for the motherboard. It probably plugs into that white socket behind it on the board, but check the motherboard manual to make sure you put it in the right place. It's pretty hard to plug things into the wrong place most of the time, but check to be sure.
- Q: im hooking up a system in my truck..im doing it the redneck way they way i have watched my dad do it many of many of times. im using jumper cable wire!! yes jumper cable wire, its plenty of juice the perfect size! but im not sure if he ever used a fuse link.do you have too? what if i dont use one? if so where is the cheapest place to get it?what size fuse is it?
- you dont have to have a fuse on your power cord but if you dont yo could end up with frying your amp if you touch the ground and power wire together so if you can put one on i dont right now
- Q: Acoustic Audio 10 inch home theatre powered subwoofer use speaker wire or subwoofer cable?
- Use a long RCA cable. If you use speaker wire - you have to run wires from the left/right outputs to the sub, then more wire from the sub to the left/right speakers. Then you have to tell your receiver your left/right speakers are LARGE and you do not have a sub to get things to work. A single long RCA cable is simpler. You can even make your own with pre-terminated CATV coax and some F-to-RCA-Male adapters from Radio Shack. Subwoofer signals work fine and do not need any kind of higher end RCA cable.
- Q: I found a box of power cables that I could use to hook up my PC and I know some of them were for old CRT monitors. Is it safe to use any of them? I'm not sure which one actually came with the monitor.
- From what I can tell, all of the monitor power cables are exactly the same. I don't see any reason why they wouldn't work or why it would be unsafe. As long as it fits easily into the LCD and plugs into your power supply then it should be just fine. (P.S. I've used old power cables on newer models before when I lost a cable once)
- Q: I'm new to PCs and I recently bought a Dell Optiplex 745 desktop PC but it came without cables. I thought I had the correct power cord but it turns out I gave it away to friends. I have the power cable that you plug into the wall which has the standard PC kettle plug (the correct one for PCs not an actual kettle plug) that you'd usually plug into an adapter then into your PC but I'm not sure if you can just plug it in without the correct adapter. I have Googled but cant make head nor tail of it all. And by adapter I mean the cable with the little box that you usually plug into a device such as a PC, laptop or Xbox 360 before you connect the cable to the mains.Thanks.
- It all comes down to the amount of output that the pc is set to take. I would think that you would be fine without the adapter, assuming it already works. If you do decide to do this make sure you set up a surge protector, dont just plug it into the wall. A power surge could fry the internals and brick the pc.
- Q: Two things:1.) Why when we're using an AC to step up the voltage the power has to remain constant?2.) Why is it if we increase the voltage by a factor of 100 we have to decrease the current by a factor of a hundred and therefore I^2R is decreased by a factor of 10,000
- Power is generated at the power station and transferred to the end user your home by means of power cables. Unfortunately, some power is always lost in this transfer process. It's power NOT Voltage OR Current that is required to operate your home electrical appliance. Yes, current and voltages are involved ;but it is the PRODUCT of these two that makes up the power NOT the voltage or current individually. Power = Voltage x Current Power is lost in the cables as heat as given by your i^2R. To reduce the losses then we must reduce the current I. But, if I reduce the current and keep the voltage the same then the power will fall and my kettle/Xbox/curling tongs will no longer work at home. So, to keep the power up when reducing the current I must compensate by increasing the voltage and this means using a step up transformer. Near the homes, a step down transformer is used to reduce it back down again. Since the losses in a cable are a consequence of I^2R heating then it is important to reduce the current as much as possible when transferring power. If we assume the the resistance, R of the cable is constant, then a 10,000 reduction in power (power/10,000) gives P/10,000 = I^2 x R I^2 = Power/10, 000R I = square root of [const x 10,000] I = 100. Then using power = voltage x current reducing the current by 100 means increasing the voltage by 100 to keep the power the same.
