Q: i soldered in one of those ribbon cables on to my hp's laptop power button cause the old ribbon was failing. anyways i am having some issues with this new cable1 the laptop will power on by itself if i insert the ribbon into the motherboard connector2 the only way to power off the laptop is to remove the cable from the mother board connector and that means opening up the whole laptop3 like i said it will power on by itself so that means that i cant turn it on/off with the power buttonevery thing is soldered correctly i dont understand also i am not sure but does the cable have to be like the old one cause the new one i soldered in looks the same? could it be that it needs that one particular cable replaced again? please help me i am sad: Time to hang up our computer repair skills and take it to a shop...

Q: I recently purchased a new power cable for my HP laptop (v6000 series) due to the disappearance of my old one. When I first plugged in the laptop, I noticed that it did not charge. I thought this might just be due to the fact that the battery has been dead for an extensive amount of time, but after leaving the computer plugged in over night, nothing has changed.What can I do to make my laptop's battery charge?Do I need to have a more powerful power cable?Thank you all for your help.: by power cable im assuming you made sure to purchase the correct model, and that you mean the cable, along with the transformer connected to it? (ac plug transformer cord laptop) if everything's plugged in, your charge icon on your laptop should let you know with some sort of animated plugged in/charging icon. if the charger is known to be good, then unfortunately you may have a loose/bad dc receptacle in your laptop. the port where you plug in the cable sometimes comes loose from wear and tear and the connection fails. try gently jiggling it around to see if it comes on when its plugged in. if it is bad, you can take it to a computer tech shop and they can fix it. just a thought.

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 have an old scanner, HP Scanjet 3400C, but I have lost the power supply cable. The power socket the cable fits into looks like a small single hole with a little pin in the middle.Can I replace it and what is it called?Thank you very much.: The power cable and adapter will probably be unique to the scanner. You'll have to order the right one from HP, or through a computer store. The USB cable should be standard. Most printers and scanners use a USB cable with a Type A connector (flat) on one end, and a Type B connector (squared-off) on the other end. They're easy to find at Staples, as well as at computer stores.

Q: Basically i want to add another ssd using a power splitter cable, however i was wondering if you could use the power splitter cable with the optical drive instead of with the current hard drive, (im asking this as there's no room to place the ssd drive close to the hard drive)Thanks: Yes it will work just fine.

Q: power cables for 3 phase wire: Three wire, single phase, 120V uses: line (usually black), neutral (always white), and ground (green or green with yellow stripe). Three wire extension cords should be sized for the estimated load in Watts, and the length of the cord. Armored cable for interior wiring must be #AWG14 minimum. Add details for a better answer.

Q: I lost my power cable and want to know if some of the others i have around the house are adequate size: some PS3s have widely used ability grant. to comprehend which one you have you're able to desire to open it. in case you do not choose to open it (and void the guarantee) - use ability converter. notice: for PS3 you would be wanting a minimum of four hundred Watt. As for ability cable itself - relies upon on the socket on your ability converter.

Q: I'm extending one of my PSU power cables because is to short. the line got 2 black/1 yellow and 1 red (molex) I know the colors have to be matched but if at the other end I end up mixing the 2 black lines, will there be a problem?ps: I already sleeved the cable for that matter I can't see the 2 black cables inside and i forgot to mark them. :): swapping the black wires will not cause any problems.

Q: I have an internal SATA drive that im looking to access through my laptops eSata (external SATA) port. Im buying the cable required for this but im curious after I make the connection is there a separate cable i need to provide power to the hardrive?Or does the sata to esata cable provide power to the internal drive: An okorder / Yes you do need a separate power cable for any SATA devices, but that enclosure uses a small controller board to make a single cable design possible.

Q: i have a SATA hard disk and i connected it with a sata power cable and recently i bought a sata optical drive and i have no power cable for connecting the drive, so i decided to connect it with the power cable of hard disk(I have two sata hard disk): You might want to get these at a local computer shop though or you'll pay more for shipping than you will for the wire itself. I would suggest the 1 SATA to 3 SATA seeings as we already know you have SATA power connectors.
