Question re cable to connect UPS to computer
The cable that connects my APC XS 1500 UPS unit to the computer seems to be defective all of a sudden.
I have no similar USB-to-RJ-45 cable handy. Could I safely connect the data-out port on the APC unit to the spare Ethernet input on the G5-Quad with a regular Ethernet cable, or am I likely to mess up anything?
Thanks in advance.
Well, I've heard back from "Shanmukhi" at APC. Typical East Indian response:
Ramon, I understand that you are facing some issue with the cable. I am afraid to say that it is not recommended to use other cable rather than USB cable that ships with the UPS.
Other than that—and after exchanging the third email—they have not been helpful in the least. Even after I've told them that a second, IDENTICAL unit is recognized when connected through the same cable and USB port, Shanmukhi gives me the usual nonsense about trying a different USB port, etc.:
I understand that the software has lost communication with the Back-UPS unit. If the UPS's USB connection is not being recognized, there are few steps that we can try:
1. Perform Reboot of the system:
a. Unplug the USB cable, shut down the PC, shut down the UPS.
b. Switch on the UPS, switch on the PC.
c. When the operating system is fully loaded, plug the USB in, and see if it is recognized.
2. Check in your computer's Bios for the following settings:
a. Legacy USB support should be ENABLED.
b. Advanced Power Management should be DISABLED.
In case, the above steps do not resolve the issue, please click the link below for further assistance:

If you have any further question, please get back to me with the following details:
1. Is the USB Host controller listed under Device Manager without an error?
2. Does your computer detect the UPS via USB cable when the cable is attached?
3. Is the USB cable attached directly between the UPS and Computer USB port?
4. Have you tried different USB ports on your computer?
Looking forward to hear from you. I will be happy to assist you further.
All of that, of course, is totally irrelevant after I've told them that: "a second, IDENTICAL unit is recognized when connected through the same cable and USB port."
Sigh…

Windows 7 license question product key in connection with other computer
I bought a new Toshiba laptop from pc world with windows 7 home premiums64bit pre-installed onto it.
I have just bought a new pc tower that is without an operating system.
I would like to know if I can install windows 7 onto the new pc and then use the product key on the underside of my laptop as I believe the key can be used on up to three separate computers.
I also would like to know how to obtain a copy of the disc with which to do the install as one was not provided with the laptop.
Thanks in advance for any assistance> I also would like to know how to obtain a copy of the disc with which to do the install as one was not provided with the laptop.
Usually you should be able to create such recovery disk using the Toshiba Recovery Media Creator tool which is always preinstalled on Toshiba notebook.
But in case you modified the HDD or formatted the HDD, you would not be able create such disk.
In case you purchased the Toshiba European notebook series, the recovery disk could be ordered here: http://backupmedia.toshiba.eu/landing.aspx
> I would like to know if I can install windows 7 onto the new pc and then use the product key on the underside of my laptop
No since this key belongs to the OEM Windows version bundled with the notebook. -

My BlackBerry PlayBook won't charge when connected to the computer via the micro-USB to USB cable
Can anybody help me? I don't know why but lately, when I try to plug my BlackBerry PlayBook into my Windows 7 laptop using the micro-USB to USB cable, it connects to my computer without any problems but it won't charge. Instead, I get a notification in the top left corner saying "Unable to charge battery with connected sorce". I have four USB ports and I'm positive that they work just fine because I plugged in some of the USBs I own into each of those four ports and they recognized the USBs without any issues. Does anybody know how I can resolve this issue? Thanks.
The notification is by design and was added to clarify that USB charging is not to be relied upon as a main method of charging. Instead RIM's good intention has caused confusion.
USB (by design) can not provide the amount of power the device needs while it's being used. Technically, it is still trickle charging but the screen has to be off (and I'd turn off Wi-Fi too) since they are high power draining items. I have verified that the PlayBook does indeed still charge but it takes much, much longer than plugging it into a wall charger or rapid charger. In a crunch it will work but the computer has to be on the entire time. A full charge would take many hours. -

Hi Imminnie,
Thanks for using Apple Support Communities. If iTunes doesn't recognize your iPod touch, this article may help:

If issues persist, a thorough removal and reinstall of iTunes would be the next thing to try:

I bought an HDTV cable to connect my MacBook Pro to my Sony TV via HDML. The TV recognizes my computer; I see my basic computer screen on the TV. I tried to watch videos on my TV but got nothing. (tried via my facebook vidoes and Youtube. What am I doing wrong?
I've got a similar (but different!) problem: I have a MacBookPro3,1 running Mac OS X 10.6.8. I want to connect to my HD TV using a HDMI to DVI cable but the MBP cannot detect the TV display. What's the solution? Is this a bug in Mac OS X 10.6.8 ? Any ideas what I can do to make things work with the HDMI to DVI cable. (N.B.: I have separate audio cable running from the MBP to amplified speakers for the sound side of things. It’s the video that’s the problem!)

my ipod touch has a usb cable picture with an arrow pointing to the itunes logo. the ipod will not connect to a computer and is unable to be turned off as there is no red power slider when the power button is pressed. what can i do to fix this?
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Connecting a second computer to BThub 4 via cable
I do not think this is a BT problem but if any one has any advice it will be appreciated.
For a long time I have had 2 computers and a laptop connected through a BT hub 3. One computer (Vista) was connected by ethernet cable with the other two computers (windows XP) connected by wireless. Everything worked well.
Because hub 3 died I now have a Hub 4. However, I need to change the way my computers connect to the Hub. This means that there will be two computers connected by ethernet cable. The original computer connecterd by ethernet cable is set up just as it was prveiously and works well.
I connected the second computer with the ethernet cable supplied by BTand anticipated it would work. Unfortunately, for some reason I can't get the connection to work despite going through the wizard process of connecting from the computer both directly and via the small home network that is already establised.
One irritating thing is that, although I select a "direct cable connection" in the set up process, when trying to connect I get a screen stating dial-up failed and a retry is instigated. I am not using a modem!
I have tried re configuring things but to no avail, so getting to the end of my ideas, i wonder if anyone on the forum could give me some guidance.
Regards
DavidHi
Thanks to you guys for your help. the main problem was the absence of a net work card. This is now in place and I can make a connection tp the internet via the BT Hub. However, there is still one problem and this is as follows.
Computer A (windows XP) and computer B (Windows Vista) are connected to a small BT hub home network via ethernet cables.
On computer B (which has been successfully connected to the hub for about 2 years) clicking on network places > " view workgroup computers" shows a map which includes the BThub, it's self (B) and computer A.
If I do the same on computer A, it shows it's self but not the othe computer or the hub. Despite this it works perfectly well accessing the internet.
Because I need to transfer files via this network I need to see the othe computer(S) and open files on them, however, I have spent some time trying to establish the presence of other devices on computer A without success.
I have checked folder permissions are granted and I have tried to view the other devices with the firewall switched off but so far no success.
Suggestions gratefully received.
Regards,

I have an iPad 3 if I use the USB cable to any printed not connected to a computer will I be able to print
No. iPads print only wirelessly. You need an Airprint capable printer,
or a network printer reachable wirelessly or a printer that can make
its own ad hoc wireless network. There is no USB connection on an
iPad.
