• DV7-1135nr / CD-ROM not detected in Vista SP2

  So, at a given time, my Vista stopped detecting my CD-ROM drive.  It is not visible in the Device Manager and there is no obvious errors.

  The drive is powered and works.  I can boot with success.  However, no chance for that it works under Vista.

  I don't know when that happened, I do not often use the drive.

  Fixed.

  I did some surfing in the BIOS and saw a corruption on the screen of boot device control, so I lowered the score of the last 47 BIOS, at 46.

  After that, Vista found the disk without problem... I guess I'm lucky that the PC still worked.  Quality control anyone?

• 1394 Firewire sound card is unable to be detected under Vista SP2

  Hello

  I have an external sound card that connects to my laptop via Firewire 1394.  This device is not detected at all Windows Vista SP2.  When I plug the unit in and the power it upward, with external power supply because it's a 4 pin Cable, Windows does not show the device in the Device Manager.

  The 1394 controller is displayed in Device Manager correctly.

  I should add that I tested this sound card with my work laptop and it was found immediately under Windows XP.  Therefore, the cable and the sound card work.

  I tried the following without result:

  • Uninstalling the 1394 controller and let Windows find.
  • Definition of the registry key for the controller: EnumerateInactiveLink

  None of them worked.

• HP 8200 elite CMT: can I use an external power supply for AMD Radeon HD graphics card 7770?

  I have HP 8200 elite CMT CPU in which 320 watts PSU is installed. I want to use AMD Radeon HD 7770 requiring more power (minimum 400 watts power supply) for maximum performance. But the fact is, the higher Watt PSU is not available for my cpu because its cables do not match that. So I ask if I can use the external power supply to power my GPU instead of the CPU power. Will be this harm to my PC?

  Kindly help me to solve this problem.

  Thank you

  Thank you for the information, @haseebkhan7310.

  I'm not a fan of using a separate power supply to power a video card.  It can cause problems.  However, here is a video that will show you how it can be done:

• No internet with an external power supply on L20

  Can connect to internet when my L20 runs own PSU, but when the battery level is low and demand for external power, internet connection is lost when my power adaptor attatched. In addition, internet does not connect if the external power supply is used from the outset. Disconnect the external power supply and run on battery, the internet connection can now take place! All thoughts.

  Try to check the polarity of the DC power coming out of the AC adapter is correct. In fact, make sure you have any dc voltage coming out of the adapter.

  I don't really understand what you describe. Do you really mean that ONLY the internet connection is affected. Everything works well on outlet. The power lights and disc are all about; the battery OK charges; the screen is lit; the fan is running and that these things will continue to work if you then removed the battery? (Except for the battery charge of course).

• Propeller works only with external power supply

  Hello

  Just got my Helix and I have some published, one of the biggest problem so far is that it will only fuel upward and stay on with external power supply, when I dock this works very well, if I disconnect it it stops, if I plug the power supply into the Tablet light it up, but as soon as I remove the power cord it will turn off I checked and the batteries are charged, any advice at 100%?

  Thank you

  Thanks for the reply, I called Lenovo technical support and they thought it was the motherboard, technology has changed and he made similarly he suspected a defective battery, it replaces and it works fine now, so it was a defective battery on the Tablet, was not getting charged, Lenovo technical support was great, fast and very apologetic the laptop so far, thank you for all the help that love.

• External Power Supply PHD 2.5 x camera

  Hello

  Does anybody know, if there is a power supply available for version 2.5 external x camera?

  and perhaps also the order number?

  The customer got offered with PSU-CAM-V, but I guess that's one for the 4 x and 12 x PHD Cams...

  Best regards, hans

  Hi Hans.

  See is one the PrecisionHDMC camera User Guide on pg 9, 2.5 x camera has a power connector as well as the 4 x and 12 x cameras of.  It does not say that the power connector is for future use, so it doesn't seem like it supports an external power supply at the moment.

• Old hard drive PS3 by USB box not detected by Windows Vista

  Hello

  I recently updated my old HD PS3 40 GB with a 500 GB one. Since then, I bought an external HD for my old HD, in the hope that I could use it as a hard drive for some files I have. However, I encountered a big problem - Windows Vista does not detect the HD.

  So far I read a lot of posts on the internet with people having similar problems, but with no definitive answer, so I hoped to get :)

  So far, I've tested the speaker on both the different 40 GB and new 500 GB PS3 in HD, as well as 2-3 computers. Nor are detected by windows... both have the power (green light is on, and I can hear the disc rotation), but are not detected on the management of the devices or programs in 3rd (SwissKnife). As far as the computer is concerned, nothing is connected.

  Thinking that it was probably a hardware problem, I whipped my laptop HD out and connected on a separate computer and it worked without me even having to he invites. This leads me to believe that the device works perfectly and its something about the PS3 HD, who doesn't like Windows.

  The only thing I have not tried is put my old hard drive to the PS3 in the PS3 and reformatting. The only reason for this is a screw on the case of the PS3 has decided, that he's not budging despite all my efforts. Its now 12:45 and I'm too tired to fight with 1 screw more! :) I really don't know not how tabling in so well, 3 others went fine and I deliberately don't screw them in tight with the new HD after I read about the problems people have had by removing the screws.

  Someone at - it suggestions at all? How to get Windows to recognize that this has something plugged in, on how to remove that last screw embarrassing! Whatever that either would be appreciated!

  Thanks in advance

  I spent days reading the forums and try solves nothing doesn't.  I have a mouse, printer, drive hard USB and fingerprint reader.  First mouse has stopped and the rest followed in the course of the last few days.  At least I found someone with an old PS/2 mouse, so I have a mouse to work to work with.  None of my devices were conflicts in Device Manager when I started it but after remove all and try resetting of USB Hub and unplug the machine, they are all not recognized.

  Hello

  Is his as well. Especially if you have the problem of speed with a single
  USB 2.0 device is attached.

  Well, if you want to try a upgrade/repair on-site Installation and then a complete cleaning
  Windows Setup.

  You can use another DVD that aren't copy protected but you you need to own
  Product key. It must be the same version 32 or 64 BIT Vista OEM. Also the system
  machine to usually sell the cheap disk since you already own Windows. Don't forget to make a
  good backup or 3 (security in redundancy).

  On-site upgrade

  This tells you how to access the System Recovery Options and/or a Vista DVD

  How to perform a repair for Vista Installation

  In no joy try a clean install or restore the system back to out of the box state (both delete

• USB connection not detected for Samsung Fascinate

  I have a smart phone Samsung Fascinate 1500.  When I connect it by USB to my computer, the computer no longer detects it as a media device or mass storage mode (although it worked fine the first few times).  The phone also does not detect the connection and simply seeks to charge the battery.  I downloaded the latest drivers and tried allowing pop ups without success.  Any ideas?  I cannot download my music, and it's a lot of time to transfer photos by other means..., including that I had to buy a SD card adapter.

  The USB port works with other devices.  I don't think that the USB cord to my phone is the problem, as others have shared this problem in other forums.  Does anyone have a solution?

  Hi Lin,

  1. have you tried to connect the phone to another computer?

  2. have you made any recent changes of hardware software on the computer?

  Test the device on another computer. Additionally, make sure that the software provided with the Samsung phone is updated.

  As you can see on the image below it is detected by the solution of measurement and Automation Explorer. I don't know how to test with visa test Panel.

  

  After that, I tried to test with the diagnostic utility, and here it does not appear in the list.

• USB mouse not detected at startup.

  Hello

  My new HP USB mouse is not detected when I start my PC. I have to unplug & plug to make it work every time. My USB ports are fine and my previous USB mouse still works fine. I deleted installation driver from the Device Manager, but no utility.

  I have Windows XP.

  No idea how to solve this problem?

  Shaan-

  HiShaan,

  I suggest you contact the manufacturer of the computer and check if USB devices is enabled in the BIOS and enable it and check if the USB mouse is detected when you start the computer.

  NOTE: Changing the BIOS / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from configuration can resolved BIOS/CMOS settings. Changes to settings are at your own risk.

  You can also check if the Interface device access human service is set to automatic and started. You can change it accordingly and check if it helps. To do this follow the steps below:

  1. Click Start and click Run.
  2. In the Run dialog box, type services.msc and click Ok.
  3. In the services window, scroll down to Human Interface device.
  4. ClickHuman double Interface of device service and click the general tab.
  5. Change the startup to automatic type, then click on apply.
  6. Click Start, and then click OK.

  Restart the computer and check if the USB mouse works fine when the windows start.

  I hope this helps. Let us know the result.

  Thank you and best regards,
