• How to control the TTi QL564P Power Supply with USB connection?

  Hello

  When I connect the TTi QL564P power supply via the USB port I see not on MAX (peripherals and interfaces) the virtual serial connection. With GPIB, everything works great!

  I already downloaded the latest drivers on the site of the IFG.

  And I created a simple VI like this:

  OPEN--> VISA VISA WRITE ('V1?") --> DELAY (0.1 s)--> READING of VISA--> VISA CLOSE

  (works via GPIB, does not work via USB)

  VISA OPEN I have the name of resource VISA only the LPT1 and COM1 ports available... so where is the USB port (this virtual serial port, case)?

  VISA GPIB resource name is the ALIAS that I set on MAX...

  Thanks for the help

  OK, the solution was... on the front panel of the power supply, I replace the USB bus (I had default GPIB )

• Win 7 (64) "sleep" and "hibernate": power supply for USB devices

  Hello: Just ordered a new PC with Win 7 Ultimate (64) and I need advice on creating a power plan. I learned the hard way with Vista Ultimate (32) that "sleep" and "hibernate" cuts the power of USB, such as UPS devices with battery backup. It was a bad function, since my UPS runs the software that automatically stops the system if necessary. However, when the Vista computer went to 'sleep', the connection to the ASI has been cut, while the UPS is no longer communicates with the central unit. Therefore, if stopped and directed were needed when the system is idle / "asleep", UPS might not make it. The only solution I could find was to create a custom power plan that stops the CPU (and that only updates the display on screensaver for X minutes and then turns off the screen). Obviously a question of wear for the system, being never in mode 'sleep'. Windows 7 behaves similarly, depriving USB power in "sleep" or "hibernate"? Will I need to apply the same workaround? Please notify. Thank you! daledoc1

  Right click on the USB device device manager concerned and select properties then power management and clear the option to Turn off energy-saving and activate the option to wake up from its sleep.

• Chroma DC power supply RS232 communication (read problem of over-voltage and current)

  Dear all.

  I chroma programmable DC power. Based on the programming of the Instrument manual I develop using RS232 communication. Based on the program I can set the voltage, current, over-current protection, protection against overvoltages and make IT / OFF out put supply perfectly.

  But I have to read the measured values of the output power as current and voltage. Measured applications are the voltage and current of the output of the power supply. My problem is two of them read at the same time. Currently, the reading is only voaltge or current (if the first request is v? it is voltage read out but no reading for the current) and if the first request is CURR? the reading for the current, but not for VOLT? The status message is OK, even if it is to read values.

  Thanks in advance

  What I see in your program, it's that you do not use the stop for reading character. For your writing, you do the hard with all these concantanate string functions. You can set the stop character for all entries with a node unique propert - "ASRL end Out.

• Upgrade power supply for dell Inspiron 530 (not slim)

  Yes, it's an old computer, but I want to upgrade the power supply for it. Watts, preferably something of 400 or more, but I can settle for 350w or 300w

  I have improved the power supply on an Inspiron 530 with an Antec 550 watt modular power supply with no problems.  Just be sure to buy a power supply of standard size, and you should have no problem.

• Power supply question - amber LED flashing - Dimension E520

  So, I'm working on the dust removal and re - install windows on a machine. I've done dusting, but now I have problems with a LED flashes orange. The system will not top all - fuel without fans or beeps.

  After looking through some posts for ideas, I think it is a bad power supply or a problem with the heat sink.

  I think power because this seems to be a common problem. How can I test the existing? Is there a way to fire unless it is connected to the motherboard?

  The reason why I am wary of the heatsink is that I removed it when I was doing the dusting. I had the intention of fire tonight and get a new thermal paste in the coming days. Since then, I have read that this could be a recipe for frying the total CPU and I wonder if the machine is not pulled up like a check for free preservation any.

  It detects if I removed the heatsink? If it's happening, it will automatically detect when the new thermal paste is in there? Or is there a reset procedure any?

  Any help would be great. Thank you!

  As a side note, the design of this box is poor. I can't find some way to dust effectively the heatsink without removing it from the central unit. Supply openings do not match, so you cannot blow a good flow of air through the box.

  A flashing orange switch LED means that the computer is under voltage, but a power problem internal may exist.

  This may indicate a bad diet

• Fan power SUPPLY XPS 8700 block

  I have an 8700 XPS which is now two weeks old.  The Tower began to make some strange electric tone and/or the sounds of gnashing especially at the start.  I removed the side cover and the noise is coming from the PSU.  Sometimes the power supply fan is running at very low REGIME and squeaks.  Other times at the start of the power supply fan turns at all and there is a strange electronic tone coming from the PSU.  If I move the blades of the fan with a plastic straw, the fan will run upward and tone noise subsides.  Faulty PSU?  The unit is under warranty, but having a Dell technician will come out can be a problem with my work schedule.  Reference Dell will send me a new power supply?  I don't mind reverse out and return the defective power supply.  Thanks for your help.

  As I suspected, the BIOS update does not solve the problem of power supply fan. But if the flash update had bricked motherboard, Dell should replace it as well as the power supply under the warranty.

  Dell computers may vary only the CPU fan speed based on heat, not their fan PSU OEM.

  Hope that the new power supply solved the problem and you can continue to enjoy your new toy.

  Post back and let us know what happens after replacing the power supply...

• power problems can be caused by a bad power supply

  May have found the solution is not sure yet - but after changing the battery in my 2008 end pro mac backup - always had problems with the screen freeze.

  As the mac was not in its usual place because of a previous repair - I had been powered to a pad of pen wacom via USB to keyboard - and using the keyboard extension cable joining the mac.

  Changed the filling of Wacom return to connection through my apple studio display, which has its own power source - and do not connect the backup drive WD Book at the fuel rail (brand stick Spike) and seemingly took care of gel to the top.

  Brought back the mac in his room with his back to regular links - but had to plug the display and the mac directly into a wall outlet, because the new power bar that I bought has a plug that does not match the output.

  Has anyone else had the question of a power strip causing problems?

  I had been turned to a pad of pen wacom via USB to keyboard - and using the keyboard extension cable joining the mac.

  I had problems with this sort of thing. I tried to run a printer, who had her so-called clean energy output keyboard 'just for the data connection"and it has messed up the keypad so that I could not enter my credit card number.

• XPS 8500 does not turn on, power supply problem

  XPS 8500 shipped on 18/01/13 so only a little more than 1 years. does illuminate, check psu and it's fine. reduce mobo or power button module. want to try to bypass the module by jumping pins on the mobo, problem is that I can't find any list of the pins for mobo or power button. Any help would be greatly appreciated since comp is barely over the years and cannot afford a new right now. Called Dell but no help it cause guaranteed missed, which took them 5 transfers and 45 minutes to tell me that :)

  If the green light on the power supply goes off, it detects an anomaly. So, it is not the power button that does not work.

  1. Visually check all ports USB for damage, misshapen or twisted for example contacts
  2. Try to turn on with nothing attached (no keyboard, no monitor, no mouse, etc.)
  3. Setting power off unplug and power button press / hold for ~ 15s open the case and carefully reconnect all RAM modules and PCI cards in their locations. Check the power cable from the power SUPPLY mobo and CPU. Cable control to all readers, video card etc... Pull the mobo battery and power press on/hold button for ~ 30, replace the battery (right-side-to the top).
  4. Check the cable to the module button before (F_PANEL connector on the mobo)
  5. Check before USB cable to motherboard
  6. Etc.

  The manual is hereif you need information about all of these connectors.

• HP Pavilion p6-2: problems on blocking down after I installed the new power supply on a p6-2207ep

  Hi all

  B4 explaining my problem, I really don't know if I should post this in office, or material in this section of the freezes/crashes/locks but since I posted in freezing section and no results I decided to try here.

  My pc: http://h20564.www2.hp.com/hpsc/doc/public/display?docId=c03382032

  I bought a new PSU: XFX TS 550W 80PLUS BRONZE for the GPU upgrade 380 R9 I was planning to do.

  Is there some BIOS I get HP for this cause of power supply from what I read, if I not only one of the things like manufacturer reset to the factory settings may stop working... Currently, my Bios version is 7.11...

  Problems with the new power supply:

  When I closed windows 7, the first problem, the picture freezes on the screen that says "blocking windows down", I waited a bit and nothing, tried to turn off the machine while keeping down the power button but nothing to disable directly in the rear switch of the PSU...

  Second time happened a little different soomething, seconds after freezing again on the screen that says "blocking windows down" windows actually turned off and the screen is off but everything inside the computer case continues to flow fans in light of the power button / stop and was also able to close by keeping pressed power button...

  When I restart the computer, to which some time stops, and only after a few seconds, it turns...

  Also tried the GPU with the new PSU fans worked but no entry in the screen that I guess just a power supply problem.

  ATM, I'm RMA waiting to know if it is a power supply defective or not...

  Problems after the reinstallation of the original material:

  Some of the same problems when I got the new PSU remained namely:

  Windows actually stop and the screen is off, but everything inside the computer case continues to flow fans in the light of the button on / off and was also able to close by keeping the power button...

  When I restart the computer, to which some time stops, and only after a few seconds, it turns...

  What I've done so far to try to fix the problem:

  Restore windows 7 to a b4 point the hardware installation.

  Reset the BIOS

  Hard reset

  Clean boot

  Do you have a full checkdisk which means 0 KB in bad sectors...

  A complete hardware checked all tests with the HP software

  A system file check everything beautiful

  What I fear most is a faulty PSU that may have caused damage to my equipment mainly the motherboard, but could be something else entirely.

  Maybe I need a specific BIOS for that motherboard / PSU combo, but after returning to the source material, the problems remained.

  What I can do because I can only make the software tests since I don't have an extra PC to test the parts...

  Hello

  Disconnect all external devices except the keyboard and mouse when you try to solve the problem.

  Disconnect the PC and removed the CMOS battery.  Press and hold the power for 30 seconds.  Now, replace the CMOS battery and plug the PC give a TI a go.

  Your PC is not stable enough to make a BIOS update. Do not attempt to use the graphics card XFX until your PC is stable enough to make a BIOS update.

• P0.0 6516-setting PCI to high causes the voltage drop across the external power supply

  Hello

  I use a PCI 6516 for 24V output. I have my power supply connected to pin 5 positive cable and the negative to pin 19. When I put the port 0, line 0 (P0.0) high heat, I have a voltage drop on the power supply to about 1.9V. There is no other son so there is no short circuit anywhere. The rest of the lines work very well when I put them on high. The automatic test works very well, and I tried to reset the unit several times. Could there be potential damage to this specific port? All the solutions to this problem, or anything that may have caused this behavior?

  Thank you

• 12V power supply blew my usb ports

  I have an Acer 5738z and stupidly I plugged a power supply of 12v to the back of a monitor in one of the usb ports on my laptop. Now I have zero usb to work.

  Can someone point me in the right direction for what could have been grilled, fried or just died?

  I'm guessing it will be a corrective work to shop, but it could be something stupid like an overload switch off. I tried a factory restore, but failed.

  Thank you

  Thanks for the reply... Managed to fix my problem by other means.

  I want to get back the abilty to connect a mouse to the laptop and with blown USB was an unbreakable wall facing, so me be me and to have this strange love of the violin I stripped a USB cable of his male end (the female leaving intact) and using a similar to an internal modem card bluetooth I took the tiny metal connectors our and carefully them wrapped in tape and they slipped on the pins of taking I would have plugged a BT Module, and then deleting a BT Dongle USB's from so I wrapped tape to insulate it and plugged... Testimonials - I now BT internal with a BT mouse and I am happy again.

  I had to get a diagram for the motherboard so I could work on the correct wiring order but got the first opportunity, and I had to remove plastic inside the Palm so it would all fit with the laptop intact.

• 3525 Deskjet printer power supply problem

  Brand new printer, I have been connected, printed OK. Once off, lights not again unless you pull on the power cord plug, then plug it in yet. Then can be turned on. But once off so the same problem all over again. I tried different plugs/Sockets, same problem with them all. Same thing happens when the printer is connected to the electric network without being connected to a laptop Desk/computer. Is this a power supply problem? Is it not ridiculous to do out of the box?

  Thanks for any help,

• BlackBerry Smartphones loading very slowly via USB power supply laptop

  When I use the wall charger, my fine storm costs.

  But if I connect it with the sync cable to my laptop - laptop is turned on with the BB Desktop software running (and I can confirm that I have a backup of the BB Desktop software then the drivers seem to work), the storm is charging is very very very slowly or not at all.

  Is it supposed to load OK via USB to the laptop power?  How can I go on troubleshooting this?

  Your question is not a problem, but normal and the answer "why" is simple. Wall charger puts out simply more power that the USB port on your laptop needs to (or can). In general, any single USB port is 100-150mA (and can be lower if your running on batteries and the system is allowed to control the ports), while the wall charger is to switch off a little more (700mA)... constantly.

  Not to mention that when connected to the laptop there is communication that passes between the device and the computer, especially if you use the Desktop Manager, which makes peripheral 'work' and try to reload at the same time. Sometimes the ' workload ' can be greater than the rate of charge, so why he does not pay at all.

  IMHO, load your device with the supplied charger. Only use your computer to charge your device in case of emergency. If you insist on charging the system with your laptop... Plug in your laptop computer, close the Desktop Manager and Device Manager and it should load a bit faster.

• Studio XPS 435 t / 9000 power supply problem

  My diet giving me in my Studio XPS 435 t/9000. The fan is very noisy, but otherwise there is no obvious symptoms. Since the system is about 5 years, I was planning to change some parts.

  My questions are:

  (1) what could be the cause of the fan to be strong, and what are the potential problems with that?

  (2) a system of 435MT 475W PSU would be compatible, or would I need specifically a 435 t?

  The first thing I would do is keep the Office of your garage. Open the side cover. Use compressed air can and blow all the dust that has accumulated in the tower. Blowing from the rear of the PSU and the inside of it. Replace the cover and retest for the noise of the PSU. The power supply 360w on Studio XPS 435MT will not work. The only Dell validated PSU for the Studio XPS 435 t / 9000 has been F217J 475w. The best video cards, we validated our eating 475w were:
  2XTG4 AMD Radeon HD5870
  5X2CH Nvidia GeForce GTX260

  You might consider installing a power supply of higher power, but with a single card video, you need something bigger then a 650w. You could then spend the video card for sale retail Nvidia GTX660.
