Q:will leaving the power cable in for my laptop hurt the battery?

Newer batteries cannot be overcharged but it is not advisable to leave the power cable plugged in when the battery is at a full charge. It will not hurt the battery but overtime your battery will not sustain a charge for as long as it should. My best advice would be to fully charge and let your battery drain to near completion and then recharge. Give your battery the exercise it was meant to have.

Q:I'm curious, because I was looking through the 'combo deals' for a part for a potential build, and one of them was a SATA cable (item itself was a hard drive). Does Newegg, or for that matter any major computer retailer, sell products that come with all the cables you need to actually use the part? I guess I'm primarily concerned with Hard Drives and Disk Drives in this case... oh, and PSUs I guess. And the mobo, will that have the power cable?

Q:Hi, Recently I bought nikon S550 digi camera from U.S, their power supply is different from India. In the power cable they mentioned 125 7A, do i need any convertor or directly i can use.

India power outlets run 220v, not 120, so you are going to need a converter or a completely new power-supply.

Q:my laptop keeep on saying installing lite on camera crystal eye and it and put implug power cable and i dontt no what one is so what is a power cable pleasssse help ?

A power cable is an assembly of two or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.

Q:I am installing a sound system in my car straight from scratch. I have built the subwoofer enclosure but now I have run into a problem. The existing amplifier power cable is too short to reach my amp. I was wondering if any other cable could be used as a substitute to extend it just a few more inches or do I need to buy a whole new amp kit? Thanks

Splices are not wise when high current is passed. It's a perfect spot for overheating. However, using a distrobution block as a splice would work fine. It won't look pretty but you can cut up a set of jumper cables as long as they're the same guage. Of course the more strands in stranded wire, the better.

Q:Whats the Power Pass mean on a coax cable splitter?

It means it can pass DC current, such as used for satellite LNBs and amplified antennas

Q:Specs on my projector reads:100 - 240v2.5 - 1 A50 - 60 HzNow I have a power cable that reads 2.5A 250v. can i use this power cable on my projector? please help!

Yes, as long as the connectors on both ends are correct, you will be OK. The 250V 2.5A rating is the maximum for the cord which is beyond what your projector needs.

Q:Many of the complete amplifier kits, example rated for a 700 watt amplifier come with a 10 gauge power cable. Many of the gauge charts from the online car audio techs, would recommend a 4 gauge wire, but they sell the amp kits with the 10 gauge. I guess bigger is better, more efficient and safer for the installation, but I would expect them to add some * adjacent to the kit specs with their recommendation.

Well in this case bigger is most of the time better. I used a 2 gauge for both of my amps. 2 guage is thick enough to handle alot of juice! And your right, 10 guage isnt always the best size for bigger amps. I assume you are talking about a big amp right? My 2 amps, one put out 1600 rms, and my amp for the high's put out 200 rms. And both of these amps ran off of the same power cable with no problems ever. Now if you are going to be running a big amp or amps, dont forget to also help out your cars alternator by also running a DEEP CYCLE battery, and also a recomended 3 farod capasitor! Good luck!!

Q:Hi,1) Is spinning down of hard disk same as removing the power cable of the hard disk ? 2) Will the IDE cable connected carry power to the hard disk when the power cable is removed ?3) How do we spin down the hard disk manually ?

1) When you unplug the power cable, it spins down, because there is no power. In order to read data from the hard disk it needs to be spinning. When it is not spinning, you cannot read data from it. Some power saving systems will allow you set the hard drives to spin down after a long time that it has not been used, to conserve power. After that, to read from the disk it needs to be spun up, and that takes a few seconds. 2)No. 3) You cannot manually spin a hard disk, it spins at 7200 (some models 5400) rpm. That's VERY fast.

Q:What type of plastic is a power cable made of? Thanks.?

Power cable isn't made of plastic, it is copper or aluminum covered with PE, PVC, or PTFE plastic.
