  I have laptop (hp probook 4520 s), the touchpad does not work. How can I turn it back on it?

  This is a question which would probably respond by HP support, because it isn't really a Windows problem.

  Are you sure that the touchpad is not just turned off? Many laptops have switches, power switch, so you can rest your palm while typing one is not worry by pressing the key.

  Sometimes, there is a button above the key, a key on the Ko, or some have a stain on the pavement you waiting/tap/double tap/etc. to toggle the pad.

  If not, you could try to go on the site of HP and DOWNLOAD/reinstall assistance the SW for the touch pad.

• HP Probook 4520 s screen does not do anything...

  Hi everyone...

  I have a display problem with my Probook 4520 s. The screen does not show anything, not the bios boot, no windows.

  It starts really normally no other problems at all. I plugged the other external VGA monitor and works very well. But the Symbols is completely disabled does not display anything. Normally, I manage my laptop with great care.

  I chat with HP support team, they suggested

  
  

  Please perform a dry boot on the laptop by following the steps below:
  1. disconnect all external devices and adapter unit
  2. remove the battery and press and hold power for 45 seconds. This should completely discharge any residual charge in the Group
  3. restart the computer by using only the AC adapter.

  But no luck.

  Please provide a suggestion/solution.

  Thank you.

  In a dark room, boot up your laptop and shine a flashlight on the LCD screen.

  If you see a very dark Windows desktop, then you have the chance.

  The backlight inverter has failed and must be replaced. If you are a kind of DIY user, then this is a repair at low cost. If this is not the case, have done so in a store could cost @ $75.00.

  If you still don't see anything then the LCD failed. It is a more expensive repair.

  If your laptop is still within its warranty period, it's time to Contact HP warranty repair service.

• Keyboard does not not on Lenovo laptop.

  Hello. I have problems with a Lenovo laptop. I can't connect to Windows because the keyboard does not work normally. The 'H' button works as a return back, for example, and I don't see what I'm typing in the password bar, I don't know what keys are what. Only a few keys to produce characters and when entering keys other system sounds right. I had this problem yesterday and I fixed by holding button FN and F4 or F7, I think it was F7, but now the same combination does not work. If you could help me that would be great. See you soon.

  I've identified the problem.

  Lenovo machine think that is pressed the CTRL key for an unknown reason. I googled and it seems someone else has the same problem with their Lenovo machine and they have an external mouse Logitech installed, I have so it would be a huge coincedence so those not bound.

  Is there a way to use the features of the arrow by pressing CTRL? Y at - there combinations like CTRL, ALT and 8 = arrow down for example?

  If so I can at least start mode without failure.

  See you soon.

  How to activate Audio devices hidden in Vista and Windows 7
  http://www.Vistax64.com/tutorials/143447-audio-device-enable-hidden-devices.html

  Connect one microphone, music player or other audio device to your computer (you want to be sure
  the mic input is enabled)
  http://Windows.Microsoft.com/en-us/Windows-Vista/connect-a-microphone-music-player-or-other-audio-device-to-your-computer

  -----------------------------------------------------------------------------------------------------------------

  Pilots may also need to be updated:

  Control Panel - device - SOUNDS - look for HD Audio Manager - Mine said RealTek high definition
  Audio (this is an example and you can have an other name/maker).

  Make sure you write down the description and model double click top - tab drivers - write version. Now
  Click on update drivers who cannot do anything like MS is far behind the certification of drivers. Then RIGHT
  CLICK above and UNINSTALL - REBOOT - this will rebuild the driver stack.

  If your driver shows 06 you have the default windows and part of the question.

  Go to the system manufacturer's website and get the latest Audio/Sound drivers - download - SAVE - go to the place where you
  Put them - right click on Reboot - RUN AS ADMIN -.

  Check the Version tab of the driver in the Device Manager as the restoration of the sound card drivers often
  and then install the latest version. Restart and check after each test, not
  rare to have to run the pilot of 1 to 4 times or more. Just the version make sure you
  installed shows upward on the tab of the driver.
  
  Then navigate to the site of the manufacturer of the device and search for the drivers more recent and repeat the installation procedure.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  Also in the search for some Audio Manager Panel (perhaps named after the manufacturer of the sound driver). Mine
  is the RealTek Audio Manager, yours can be quite different name if you have one.

I have try several solution, but none of them can help... So, I hope that the next solution can help me... - thanks-

  Hello

  (1) since when are you facing this problem?

  (2) remember to make changes?

  This seems to be a hardware issue, contact Acer to support more specialized on this issue.

  The following steps are worth a try:

  You can check whether your keyboard works before starting Windows. To do this, you can try to enter in safe mode

  
  Start the computer in safe mode. To do this, follow the steps below:

  Access Advanced Startup menu options by turning on your computer and pressing the button F8 continuously until Windows starts. In the boot advanced options, select Mode safe

  I would like to know if your keyboard works in safe mode.

• How is it, my original keyboard does not work on my desktop, but works on my laptop? And my keyboard works for both laptop and desktop?

  Hello

  I have a desktop computer Windows 7 Home Premium 64-bit with an ASUS M4A87TD EVO motherboard. Recently, I have a problem with my Wired Saitek Eclipse PZ30AU keyboard: when I type, the typical button does not appear on the screen. In other words, the keys are unresponsive. The keyboard is turned on, if the office is enabled/disabled. Even if, at the time, while he was working, the light is always disabled whenever the office is off. I don't know why it is informed, even if the office is off.

  My wired mouse usb works fine. I even tried my USB adapter for wireless network in two USB ports, and I still have the signal, so I guess it works very well too. The on-screen keyboard works.
  However, I tried to connect the keyboard desktop on my laptop and for some reason, what works. I also tried to use a different keyboard on my desk, and it actually works.
  I downloaded the chipset, the driver M4A87TD EVO BIOS 2001 driver and a driver of NEC Electronics Corporation USB 3.0 controller. But first, I had to install the Akamai NetSession Interface. After that I downloaded all three files, I installed the chipset driver and USB driver in uncompressing them, by clicking on each file, by clicking on Setup. For some reason, the BIO 2001 pilot had only a ROM file, so I just deleted total. After installing and restarting the computer, the keyboard does not.

  I want to emphasize that, before even manually, download the drivers, I tried using WIndows Update to install all important and recommended updates. After the computer restarts, the guarded keyboard lights flashing on and outside.
  So, I ask two things:
  1.) how does my original keyboard does not work on my desktop, but works on my laptop? And my keyboard works for both laptop and desktop?
  2.) can I keep I have installed the drivers or uninstall them?
  Thank you.

  To run all the applications of the laptop or install download applications works does not error message indicating that the application is not valid "win32.exe or win32.application.

  Hello m.velentino,

  Not sure if you are still having the error message isn't valid win32.applicaiton.

  Get the error: not a valid 32-bit application can have several origins:
  I have listed some of them below.

  The file is corrupted, bad or missing.
  -If the hard disk is damaged or hurt it cause work programs to fail, either because not all data can be read from the hard drive the program is damaged on the drive. Run scandisk and defrag on the hard disk to check for potential errors.
  -If you run the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer, you can get this error.

  File is not designed for your version of Windows:
  -If you try to run a program that is not designed for your version of Windows, you can get this error.
  -Although many old programs designed to work in older versions of Windows will work with new versions of Windows, unfortunately, not all programs will not work.
  -If the program is an MS-DOS program more former start program or Windows, you can get this error.
  -If the program is designed for a 64-bit version of Windows and you are running in a 32-bit version of Windows, it will not work and generate this error.

  File is a virus, worm or other malicious program file.
  - This error can be generated by a file that is a virus, worm, Trojan horse or other type of malware file. Often, this will result because the antivirus installed on the computer will not allow the file to install or run. Try to analyze the file to check, it is not a virus or infected.
  -If the file has been checked and is clean, it is always possible that the virus protection program or a another program installed on the computer is at the origin of questions during installation or execution of the program. Start the computer in Mode safe and try to run the program. start the computer in Mode safe will be that nothing is running in the background that could cause this problem.
  
  Hardware incompatibility.
  -If you get this error during the installation of a program, it is also possible that the CD-ROM drive or the drive that you are installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.
  -Download the latest drivers for your CD player or other of the manufacturer of the computer or the manufacturer of the equipment. (Microsoft does not pilot for other materials)

  Let us know if these suggestions help you.
