- 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
- You okorder /
- Q: I need a low profile extention to the exsiting power cable so it can run along the skirting to the mains socket.I was thinking of joining flex wire to the existing cable, wrapping the 3 cores with heatshrink, and then wrapping the whole thing with white insulation tape. the guy from maplin told me I could do this but then I''ve heard that this is a bad idea (and probably against UK safety regulations).
- What I would do is make an extension up and just plug the heater into that. When you don't use the heater anymore use the extension for something else. Normally you need a Janus plug a normal plug and 2.5mm^2 three core flex. You can solder the wires and heat shrink it, just make sure the solder join is done well. If you just twist it together it might heat up and burn.
- Q: I have had my ASUS laptop for just over 2 months, and I've realised the power cable whilst being securely in, and charging without a problem, feels slightly loose when wobbled. I know this isn't a problem at the moment, but is this right, should it feel slightly loose? It moves quite freely inside the socket of the laptop when moved
- Sounds fine, but if it becomes a problem then take it back to where you got it and explain the problem. They will fix it for you, for a reasonable price. My computer started off like that, then it started refusing its charger, and still does now. When we got it seen to, the fixing chap tried his charger on it, and it worked fine so we now need to buy a new one, but they are pretty expensive things. It may not end up like that for you, but whatever it could lead to, I wouuld get it seen to, because believe me, it stops accepting its charger, hibernates on you- then bang and the work is gone! :-(( Good Luck!
- Q: I just bought a new motherboard and it had a 24 pin power thingy, my power supply was only a 20 pin. After looking at my manual it said I was able to do that if I aligned them a specific way. After that PC turns on, the lights turn on, hard drives turn on, and everything else. the thing is the screen stays black and says no signal.I was looking on the motherboard and there is a 4 pin ATX12V1, but there is no such cable that comes out of my power supply. I think the reason the screen stays blank is because it said that was used to power the CPU. What can I do since I do not have a ATX12V1 cable that connects to my motherboard?The only cables that come out of my pwr supply are for the IDE and floppy.
- Buy okorder for little to nothing depending on what you are looking for. Gaming and lighted ones are going to cost a little more but you should be able to pick one up cheap!!! Hopefully you bought the correct motherboard! But you are definitely going to have to have the correct power supply to feed the proper amount of power to your CPU! ;-)
- Q: I have my Clearwire modem but have lost the power cable. Does anyone know what I would look for in a replacement power cable.
- check the Clearwire URL .. Support tab
- Q: I like to play my PSP at home quite a bit. When I do I plug in the AC adapter so that the battery power doesn't get used up unnecessarily. I see that when I have it plugged into the wall that under the system information it says that the power is being used from an external source instead of the PSP's battery. I take it then that the battery won't overcharge and it's OK to use it this way, or do I have to remove the PSP's battery when using the power cable?
- It is fine. The PSP is just telling you that it is taking power from the outlet instead of the battery.
- Q: I want to switch to cable phone (indeed, that Triple play service offered by companies as Optimum or Time Warner). When power fails, you dont?expect to have Cable TV or internet, but phone service is different. You really need it all the time. Some people told me outages affect cable phone service. I?m very concerned because some neighborhoods in my city have had blackouts recently.
- I specifically put that question to my cable provider a few months ago. This was the official answer Quoted: ----------------------- Hello Jeff. Thank you for your email. The answer to your query is surrounded by a few variables, the main one being your proximity to the ‘node’ that your Internet service feeds off. In the event of a neighbourhood-wide power outage, our “nodes” are equipped by back-up batteries that may be able to supply the required signals for the modem to receive and transmit, though limited in duration. But as with any supposedly fool-proof system, there always exists the possibility of fortuitous failure. Please let us know if we can be of further assistance. Bob. Rep. no. 2597. E-Services Calgary, Telephone: 310-SHAW, Shaw Communications Inc. --------------------- So, in short, they do have battery backup for Internet on the local nodes... but for how long it will last is unknown and not guaranteed. That said, I am currently only using cable Internet to transport my VoIP services. I pulled the plug on my local telco, months ago. I have my cable modem, router, VoIP ATA adapter, and cordless phones connected to a battery-backed-up UPS power supply. But, these are all only temporary backup solutions. If you feel too nervous about not having phone or 911 service during a power outage... then, don't do it. Or, get a cell as your emergency backup comms.
- Q: What is the meaning of the cable 3 * 1 * 0.8?
- Symmetrical receptacles need to be treated differently, with color distinctions most convenient.
- Q: I forgot the power cable for my PS3 at a friends house and was wondering if the power cable from my computer would work. It would fit and everything, but would it mess up the system?
- The power cables are identical from PC to PS3.
- Q: how much will a xbox360 power cable go for, and the tv wire to connect the xbox and tv.seprate prices please?
- If you mean the Power Supply Brick AC Adapter and cable and the Audio-Video cable, you should really sell them as a lot. On OKorder the two combined usually go from $20-30 with free priority mail shipping. If you are really intent on selling them separate you should expect around $10 for the Power Supply and around $5.00 for the AV Cable. Never say never, but you will NEVER get $50 for those items.
