  installed a keyboard and wireless mouse and the mouse works fine, but the keyboard types the wrong keys! Any ideas? Thank you

  Wired or wireless - is usually not serious unless the wireless can get more interference.  If the keyboard is close to the receiver which is connected to the computer and you get the strikes hurt - my suggestion is to try first the keyboard on another computer.

  To do this, * not * require you to install specific drivers.  Simply unplug the combo of a computer and in the other and see if the keyboard works correctly.  Then, you can troubleshoot from there.

• MacBook Pro 2015 turns on but the screen remains black...

  Hello

  Today, I tried to turn on my MacBook Pro, but my screen stays black. When I press the caps lock button, it turns green which I guess means he lit. I've also heard the startup chime it generally makes when you turn on. I already tried to turn it on and off several times and reset the SMC and the LANDAU... The screen is always black.

  Could someone help me please?

  Also a few minutes ago the fan has started to make noise in the macbook...

  But the screen remains black.

  Thank you

  Shaynidw

  Hi shaynidw,

  From your description, it seems that your MacBook Pro is powered, as soon as you hear the startup chime and see the light on the keyboard.  Thus, it seems that the problem may be with your screen or the video card.

  On the screens you see when you start your Mac

  Power on

  

  When you turn on your Mac, display is off (black) and you hear a startup chime. Your Mac Initializes his BootROM and memory (RAM live). It then performs a power - on that self test (POST) and a test of BootROM. If you hear beeps or chimes at this stage, this indicates a possible hardware problem and start stops. If you add memory to your Mac, check that it is installed correctly.

  White screen

  

  After that only walking self-test is completed, your Mac sends a video signal to your connected screens. The screen may appear black or grey at this point in the boot sequence and backlight of the screen should light up. If you do not see the image appears on your screen after a few moments, try increasing the brightness of your screen. If you use an external monitor, make sure it is properly connected and turned on.

  shaynidw, if set up the brightness of your screen does not help, you have an external display (computer screen or TV) that you can attach to your MacBook Pro to test?

  In addition, you can try to start your computer in safe mode to see if you get different results.

  Try safe mode if your Mac does not end commissioning

  If the problem persists, you may need to take your computer to an Apple Store or service provider authorized Apple , so they can inspect the video card and cables to isolate the problem.

  Take care.

• Acer blue 720 and the fan are on but the screen remains black

  Hello

  I appreciate any help that can be provided.  I tried to remove the batter on my daughter 720 and reinsert, but this problem persists.  I can hear the fan and the blue light turns on but the screen remains black.  I tried to rest for 30 seconds and esc, refresh and power.

  Thank you

  Well, when the scrween does not at all (even in text mode which allows a recovery) then it is most often a problem with the cable bwteeen the motherboard and screen, most often following it is a failure of the screen (which requires generally a matter of co-location as cracked screen) and from time to time, it is the motherboard. Probably time to contact Acer support to see on a repair.

• 520 TouchSmart all-in-One begins, but the screen is black.

  Hi all

  I had a Touchsmart 520 for 2.5 years (warranty expired it y a.5 year) and enjoy a lot of the computer.

  One day the screen flicked once, and since then, he's black.

  The computer is still active. I can turn it on and can be accessed via the network.

  The problem is that the screen.

  I ordered a new screen from ebay, but of no use. I got a new MB, but always the same question.

  I even tried to take graphics cards out there (as I thought Valentine's) and I tried to use the support of the onboard graphics, but still no use.

  So, new screen + Mo + LED backlite, the computer is running, but the screen is black.

  One to the rescue?

  Thank you

  Roye

  Hello again Roee,

  Thank you for the updated information and I can actually respond directly to the question of how it is connected. You're right it's the LG 6pin cable that provides power to the converter card, while the backlight is also connected to the converter card. I am providing you with a link to the list of HP parts store the parts of your computer where you can see the part number 654251-001 - rear panel light FFC (LG 6pin) 250 mm. You will also see the part number 653864-001-23 converter card which you may need to replace.

  You can also buy the parts there, too, if you wish.

  I was unable to locate the manuals or documents that would give you clear instructions on how to properly install the BACKLIGHT, but you can follow the basic steps in reinstalling the converter card that I have set out below:

  Step 1. Gently detach the connectors of power and backlight of the Board of Directors
  Note that the location of the connector backlight will vary according to the manufacturer of Panel
  Step 2. Remove both screws of the card and pull the jury on the PC
  Step 4. Align the two holes on the plate with the spacers inside the unit
  Step 5. Replace the two screws of the Commission of the converter
  Step 6. Replace the connectors of power and backlight to the Board of Directors
  Step 7. Set the DIP switch on the Board to match the configuration for panels manufacturers

  The configuration of the DIP switch for each manufacturer of Panel is painted stencil on the converter card itself

  Please re-post if you need extra support. Thank you again for post you on the HP Forums. Have a wonderful day!

• Satellite X 200 - 15 K power on but the screen is black

  Hello

  I have Toshiba Satellite X 200-15 K, two days ago, I have problem with screen, the screen I have noise, I think it's the same error in my display driver and I have stop near windows xp and try to after 1 min, but the screen has more noise when the startup boot image and I stop by button / stop on laptop.

  Then do what I ve tried again to turn on my laptop but on the screen, I see only artifacts (same squadrons of colors) and after that, my laptop can not work, I tried to power on him but I only power led and HDD light works only 5 sec and after off the coast, and the cooler works 5 sec too and after offshore.

  I tried to remove the battery and the RAM and the wireless and all that I can :), but nothing happens, but when I try to power without RAM I see on power light beep two red and two yellow (IE my motherboard work).

  Maybe it can help me. I think I have dead motherboard.
  And for me, it is interesting that someone may have similar problems.

  Thank you.

  P.S Sorry for my English :)

  Hello

  Let's summary.
  You had a few artifacts on the screen, and now, you are not able to start the unit.
  Nothing appears on the screen; Neither the Toshiba start screen appears is good?

  Hmm seems material issue I m thinking about GPU (graphics chip).
  What do you think of this?

  If it's really a problem of graphics card, then you will need to replace the motherboard.
  In most cases the chip belongs to the mobo anyway... something like this can be done by an ASP in your country.

  Then please get in touch with the guys to get more details about this

  I wish you good luck

• OfficeJet pro 8600: printer works fine, but the software is not

  Printer works fine.

  However, the HP support the program "HP OfficeJet Pro 8600" will not start. I can see it in the HP folder under all programs, but clicking on the program name has no effect. The program name poins to "C:\Program HP HP Officejet Pro 8600\Bin\HP Officejet Pro 8600.exe" - UDCDevicePage Start

  In addition, in devices and printers in Control Panel, the printer connected displays. By double clicking on the icon takes me to...

  

  Opening HP All - in - One Printer Remote takes me to the window right... but the printer shows offline, and the various functions (scan, fax, etc.) are not available. (As noted, the printer is currently online, and I can print correctly.

  Connection to the wireless printer.

  All these functions work fine if I call them from the physical control on the front of the printer Panel.

  I don't know if these are two separate issues, or the two aspects of the same problem.

  Any thoughts?

  Thank you.

• my 6 more seems to work but the screen is black

  My screen is black and cannot answer incoming calls or outgoing call unless it uses bluetooth to make or receive calls

  Press the sleep/wake and home buttons and keep them for at least 10 seconds.

  If this is not enough, take a look at these articles Support from Apple:

  If your iPhone, iPad or iPod touch does not respond or does not turn on - Apple Support

  Use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

  As a final step, try recovery mode. Turn off your unit, then plug it to your computer with the hold home button. Hold down Home button until you see the logo on the screen of your iPhone iTunes. After that on your computer, you should see the iTunes window saying that your iPhone needs to be restored to factory settings. Click Restore.

• Peripheral Ethernet on Envy 15 j150us works fine but the link light is always off

  When I connect the ethernet cable to my envy 15 laptop computer j150us one however second superior of two led indicators which is a psychic link never lit, i.e. activity light blinks and internet connection works fine.

  Can you please help clarify this question?

  Sorry, I misread it.  There is no contradiction.

  This sounds like the LED link may have failed.

  You can contact HP for warranty service to make arrangements for repair if you wish. The downside is that there will be replacement of motherboard of envy. This means that there will be long you won't have your laptop until it is returned to you. On the other hand, the link led is not so important if the wired network connection works, so you'll have to decide whether it is worth sending for this fault.

• Alienware x 51 starts, but the screen remains black.

  I bought my x 51 all with warranty 1 year ago a year and a half, recently it has been giving me some problems and today I can't use it yet at all.

  The problem started with my screen remains black when I turned on my computer (punt, never awake from sleep), but which would be corrected by me once or twice by restarting the computer. That did not last too long, and soon it did not matter how many times I rebooted the computer. I finally had to unplug the computer and press and hold the power for 30 seconds to see if it worked.

  He did, but this solution has worked only once, and now I have nothing seems to regularize my situation. I tried switching monitors and cables with my brother (who is an identical 51 x), but nothing has worked.

  To summarize:

  My computer turns on.

  Not funny lights or noises (save a beep on startup)

  Screen remains black on reboot of the screen it says he receives no signal and falls asleep.

  No problem when it runs normally (not funny colors, stripes on the screen or blur).

  Help, please. Dell support wants 70 to 110 dollars to listen to even my problem, which is money, that I don't have at the moment.

  Thanks for anything that might help!

  Sounds like you have a dead video card, from the link above looks like there is no output from vga Intel to tun tests, you must remove the old video card and test with another video card that works to verify that the card is in fact dead, like your brothers x 51 remove the video card and test it on your machine.

  If I had this machine in front of me I would use one of these babies for once then run tests on the video card.

• Satellite A300D is runnig but the screen remains black

  Hello!

  I have a big problem with my Satellite A300D.

  This morning I forgot to connect my laptop to the net elec, and so my battery drains.
  When I reconnected and restarted my laptop I could see the Toshiba and splash screens of Windows, but after these the laptop screen becomes black.

  You can see the cursor, but the rest disappeared.
  The screen is all black.

  Strangely, when I press ctrl + alt + delete, the vista opens again, and I can select and view the Task Manager.

  What should I do!

  Hello

  There is a solution that could help bring back the screen.
  in Notepad, remove the battery and unplug the AC adapter.
  Wait about 30 minutes and reconnect the two parts.
  Then try again to put the laptop.

  In many cases, this procedure helped to set something like this.

  Good luck

• Series read the analysis of the data works fine, but the polarity and point decimal placement does not

  I'm new to labview and work on a project that accepts the biotic data. I have read the information and analysis data correctly but when I try to set up the number the polarity and decimal pt do not seem to be correct. When the polarity is negative, a 1, the number that came out is positive. I have posted before and was invited to use the concatenation and the power of 10 and I wonder if it's okay. Should I be looking for the 1 (negative bit) and negate the number at the end before the release?

  I have another question: how to accept a number between the touch screen and just write this number in an output file? I searched in the help and online but found no example.

  Any help would be appreciated.

  I have included my vi.

  Thank you

  I'm sorry, I apologize. I thought since it was a new problem to a new position. I've corrected the problems mentioned in this post me. Oh and when I created the project/vi I created it as a touch panel.

  Thanks again.
