Yes ehsan is right, you need to replace battery. But before buying you should check the main power section of the UPS.

Power supply not working


If the power supply isn't working by that you mean the light on the back of the power supply when the power cord is plugged in does not luminate green ? then yes it is bad. There is also a paperclip trick you could try depending on how tech savy you are. Google paperclip power supply self test. Bottom line if the power supply is bad its a relatively simple fix. Go to your local pc shop pick one up for 20-40 bucks and crack the side of the case and take note of the wires when your unplugging them from the motherboard, cd, hard drive and floppy and replace with the new one you bought. hope that helps. Thanks.

Unknown device sm bus controller


What I do in such circumstances is run a little piece of freeware called "Unknown Device Identifier" which does a pretty good job of telling me what device is not working properly, identifying the manufacturer, which allows me to look up the support site and get the driver necessary to correct the problem. I've found that to be the quickest and surest way to resolve such issues.

You can also try double clicking the device in device manager and then selecting "update driver" and see if Windows can locate it on your hard drive or search the internet [providing you have a working connection] to find the appropriate driver and install it. I find it works about half of the time.

There is are other trouble shooting methods and the Microsoft Knowledge base does the most straight forward job of defining them so rather than reinvent the wheel I'll present them as written there:


The main reason for Unknown Device to display in your Device Manager is because you have a device that is not working correctly. To fix this issue, obtain an updated driver for the device.

Use the following methods to enable Windows to recognize your device. Method 1: Windows Update loadTOCNode(3, 'moreinformation'); Visit the following Microsoft Web site to see whether the Web site autodetects an updated driver for your device. Install all recommended drivers. http://www.windowsupdate.com (http://www.windowsupdate.com) Method 2: Download and install the latest driver from the Internet loadTOCNode(3, 'moreinformation'); When you download a driver from the Internet, download the Windows XP version of the driver when multiple Windows versions are listed. Use one of the following options:
  • Visit the Web site of the computer manufacturer if the device came with the computer.
  • Visit the Web site of the device manufacturer if the device was installed after you purchased your computer.
  • Visit the Web site of the device manufacturer if the device was preinstalled on your computer and the computer manufacturer does not have an updated driver.
Look for a Drivers section or a Download section on the manufacturer’s Web site, and search for the device name. Download and install the Windows XP version of the driver. Advanced user section loadTOCNode(2, 'moreinformation'); This section is intended for advanced computer users. If you are not comfortable with advanced troubleshooting, you might want to ask someone for help or contact support. For information about how to do this, visit the following Microsoft Web site: http://support.microsoft.com/contactus (http://support.microsoft.com/contactus) Causes of unknown devices in Device Manager loadTOCNode(3, 'moreinformation');
  • The device does not have a device driver: When a device driver for a device is not available, Device Manager displays the device as Unknown Device and puts it in the Other devices branch. This is very common with universal serial bus (USB) and Institute of Electrical and Electronics Engineering (IEEE) 1394 composite devices. Also, a status of Error Code 1 or Error Code 10 may be displayed when you view the properties of the device in Device Manager.

    Note Most USB and IEEE 1394 devices function correctly without additional device drivers because they are configured by the drivers that are included with Windows for these bus types. However, an additional device driver is needed if the device does not fit the defined and supplied Windows class drivers. If the bus cannot identify the device, it interprets the device as a composite device and then reports it as such in Device Manager.
  • You are using a Microsoft Windows 98 or Microsoft Windows 95 Device Driver: You cannot use virtual device driver (.vxd) files that are common to Windows 98 or to Windows 95 drivers in Windows XP. If you try to install them on your Windows XP-based computer, the device may be listed as unknown in Device Manager. This typically occurs when the device driver manufacturer does not correctly differentiate between the two drivers or assumes that Windows XP can use Windows 98 or Windows 95 .vxd files.
  • Unrecognized Device ID: Every hardware device has a special identifier that is used by Plug and Play. This identifier can include several different types, such as vendor ID, device ID, subsystem ID, subsystem vendor ID, or revision ID. If a device ID is not present, or your Windows XP-based computer does not recognize the device ID, Device Manager may list the device as unknown.

    Note Software programs that require virtual hooks into hardware may create these devices. Additionally, devices that bridge between bus types, such as a device driver that enables a parallel port device to emulate a SCSI or an AT Attachment Packet Interface (ATAPI) bus, are also known to generate an unknown-device response in Device Manager.
  • Faulty Hardware or Firmware: Faulty hardware or firmware may cause a device to be displayed as Unknown Device in Device Manager. Software-only device drivers do not expose a device ID, and there is no standard method for installing these devices. Some manufacturers install the device by using the InstallShield installation program or a similar method. Be aware that software installed by other methods may not be completely removed when the device is removed in Device Manager. Therefore, you may have to check the registry to verify that all entries are removed.

Hugesnet HN7000s Modem Only the power light comes on.


what seems to be the issue? i'm a hughesnet install/repair contractor

as a catch-all heres some places to start....

we'll start with the 5 lights on the front of the modem:

the top one tells you if the ethernet cable is plugged into anything.... if it's off check to make sure that cable is plugged in. if it is....replace the ethernet cable, they are cheap and available virtually everywhere from walmart to radio shack.

the next 2 lights are for transmit and recieve.... they should blink a lot but not in any particular pattern. if either of these lights is acting funny you could have cabling issue (ie: improper fitting, rust on the line, messed up groundblock, or even a severed cable), a misaligned dish, or even a blown radio (its far more common to blow out the radio than to blow out the modem...especially on those 7k systems) you might be able to correct the cable issue yourself with the right tools, but DO NOT attempt to re-align your dish....its touchy. btw i should state that if hughes catches you monkeying with your hardware they'll yank your warranty....either dont do it or dont get caught.

next light down is the "system" light. this tells you if you are connected to hughes. this light will be OFF of there is a problem with the transmit and recieve. if there is no problem with the transmit/recieve and this light is off there could be a billing problem at the other end. contact support.....you'll get a guy in india or the philipines or something that says his name is "harry" or "john" or "fred" or something american sounding. this always cracks me up.

next one down is the power light. if you have other lights on but the power light is off it indicates a broken modem...no way around it, you're gonna need a new modem.

ok, on with the trouble-shoot. if your top light is on you should be able to use your computer to look at the modem using a browser (firefox, internet explorer, safari, etc) type in 192.168.0.1 in the address bar. you should get a interface with some colored buttons across the top. the system status button should be green...any other color means trouble. the other 3 should be blue. if you cannot connect to the interface the trouble is user-end...bad ethernet cable (as mentioned before) or something beyond-the-line from the modem is messed up (router, computer, or something)

if you have any red lights you can click on them to see what's wrong. any problem areas will have red flags with error codes next to them. write these down as they are useful to diagnose what is actually wrong with the system.

if your system status button is yellow, click it....most likely you have "fapped out" (violated hughes' fair access policy) btw you can look at your signal strength too....there is no way to tell you what the signal strength should be since i dont know which bird (satellite) you're pointed at. each bird has a different acceptable signal strength.

let me know what you find and i'll see what i can do.

UDS10 reconnection problem


Try the LS100 from www.sena.com, it has a better warranty (5yrs vs 1yr) and its about half the price of a uds-10. We've had the same experience with the four UDS-10's we have and now 3 of the four have stopped working and report the following error: "FATAL ERROR 01/Setup memory: Contact tech support". I called there tech support and the guy (Marty) actully told me that the units have exceeded their life expectency. They all failed within the first ~22 months of operation. Working in a school district we cannot afford to keep doing the same thing over and over and over again, so our next project which involves 15 building will all use the SENA LS100 product and save the district money and have way better support and warranty. Thanks goes to "tech support" person Marty at Lantronix.

Landline phone


I gather you are using an IP phone. I would have to say that the only way to trouble shoot is to use a protocol analyzer. If you connect it within the IP path you will be able to see both ends of the call and determine if the call was received or not and if the other end is responding to your call. Your IP PBX might be the problem I would run a diagnostic on it and if it fails, I would suggest calling the manufacture to see if there are any tests you can run.
