• 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.

• BSOD BCCode 116 - generated after installing updated drivers for ATI Mobility Radeon HD display drivers for HP Probook 4520 s 5470

  I continue to work through issues with my HP Probook 4520 that is now almost 4 years with the same problem of a frozen screen.

  Today, I decided to work in seeing if there was new ATI Mobility Radeon HD 5470 available display drivers.

  I have the version of 15/03/2011 of the ATI Mobility Radeon HD 5470.  With that came the AMD Catalyst install Manager Version 3.00.0868

  .

  During his visit the HP site I saw that they had a newer version available on the graphics card available with the date of April 30, 2011 and the download file has been identified as sp52818.exe for the Version of the graphics driver to download 8.743.2-- 110315 5A - 115833C.

  In light of the penalty, that I got with my graphic display driver 15/03/2011, I decided to uninstall the drivers of my 15/03/2011 and download the drivers of 30/05/2011.

  Doing this has my computer I notified that I already have the sp52818.exe file and so I was a little confused, but I allowed him to install over my existing file.

  To install the file sp52818.exe successfully, I went to work.  Then after some time (within an hour), I got a message generated by computer at the bottom right of my screen saying a newer version of my graphics card was available at www.amd.com .

  (first thought was - why HP had it?)

  In any case... I decided to click on the suggestion box, visit www.amd.com and see what they had.  I was directed to install a driver to automatically detect the utility, and during the installation, the utility's suggestion came back that my computer can access a new graphic display driver.  I thought it was nice and so I then proceeded to of course download the .exe file for my HP probook 4520 s.  The proposed file was qualified: 13-12_mobility_win7_win8_64_dcl_ccc_whql_exe (graphic display for the ATI Radeon HD 5470 by suggestion of AMD driver.)

  Everything goes well.  It starts to download the Catalyst install Manager Version 08.00.0915, then the ATI display drivers with > .NET Framework 4.5 (I'm just observing things that are facts).  Several times the black screen comes on, but that is to be expected.  I wait patiently, and finally I see the green bar of progress.  Just as the green bars come in the end, the screen goes black again for about 1 to 2 minutes.  Then suddenly the dreaded BSOD Blue Screen of Death comes with an error message saying that something has gone wrong and closing of windows, and he mentions something about Windows display drivers.  I'm not panicking yet, but is offered the possibility of recovering and I let the computer pick up normally, and I return to the screen of welcome with happiness and connect to.

  From the entrance, the first thing I see is a Windows Error Message, I opened and saved and here provide for our education and research.

  I'm not able to open the .dmp file to display as the file associations cannot establish a connection, and I am unable to find the AppData file under users.  Windows 7, it is extremely difficult find the files suggested by error messages.

  I would like to know why the BSOD appeared, then please explain the error message that came as I was trying to install a driver recommended for my computer using download driver acceptable practices, causing me concern and frustration, as well as the 4 years of intermittent to faithfully display failure.  I'm not sending the machine backwards.  There must be a solution.

  (Rabbit Trail - the suggestion to display the privacy statement is also an attempt to distract people to get a real fix and do believe that Windows 'help' you who isn't.)

  The laptop is running and I can see things on the screen.  It seems OK, but I'm going to face other issues?

  You are right that the accident may have been caused by the newly installed ATI driver. I checked on the HP Site and there is a version of the same display offered with the same output driver date on the ATI site, so the difference may be that the version of HP's specific system, while the ATI Version is just generic, so my suggestion would be to uninstall the ATI Version and replace it with the HP driver.

• Recovery partition engage F11 starts after stock Win7 installed - Probook 4520 s

  Laptop: HP Probook 4520 s (with the Energy Star label)

  OS: Windows 7 32-bit

  Error: Nothing happens when you press F11 at startup

  Deliver changes: installed Windows 7 from stock disc Windows 7

  I am a PC technician with quite a few years behind me, but that gave me even after a day of research solutions to stop online.

  A friend bought a ProBook 4520 s where the previous owner, just before selling it, installed Windows 7 on a disc of Windows 7 Microsoft stock (I suppose that pros sell with a 'clean' OS), who of course ERA naked place without drivers, etc..

  When the installation has been made however, it didn't destroy the partitioning of HP (that is to say, the scores remained: SYSTEM OS (c:\), HP_RECOVERY, HP_TOOLS). These scores seem intact, so I am trying to run a HP recovery to return the computer to factory settings.
  When the computer reboots, I am asked to press 'ESC' to the options, what I do, then it prompts 'F11' for HP Recovery. When I press F11, it starts only the Windows 7 operating system as usual. With what I've managed to collect via search, I think something was disturbed on the HP_RECOVERY as the MBR partition, or something, possibly by the previous user making the active HP_RECOVERY partition, then selecting "Repair Windows" on the Windows disk.

  I tried solutions include:

  • Pressing ESC-> F11 at startup [simply boots as usual].
  • The definition of the partition HP_RECOVERY 'active' disk management, and then restart [simply boots as usual].
  • Installation "Enhanced HP Backup and Recovery Manager for Microsoft Vista" (sp38131.exe) [when it is run, and the recovery of the PC is selected, it is said there is no partition recovery and demand for drives].
  • Installation "Fix for HP Multi-Partition Recovery Manager" (sp48415.exe) suggested to the 'green post' here [no change].
  • Installation 'Recovery Manager install for Microsoft Windows 7 Upgrade Patch' (sp45823.exe) [no change].
  • Install "HP Recovery Manager for Microsoft Windows 7" (sp45602.exe) [no change].

  I live far from having access to the purchase of HP recovery DVDs, so need a solution for this problem, please. At most, I can download.

  The operating system in recovery, I expect Windows 7, because there is a Windows 7 sticker on the laptop.

  There is not any way I know how.

  In addition, the recovery disk is a plain OEM version without drivers or software.

  The DVD driver and application automatically installs the software and drivers that are on the recovery partition, but it is on the support page and driver of the laptop (with the exception of the DVD software, which isn't a big deal since you can play DVDs in W7 w/o any 3rd party software).

  Just download and burn the ISO using a ISO burn option and reinstall W7.

  If you can't find the drivers, please read this guide to find the hardware ID and after the first string for each of them, and I'll give you links to the drivers you need.

  http://laptop-driver.blogspot.com/2009/12/how-to-check-hardware-ID.html

  I always delete all the partitions and reinstall a clean OS on any PC, I am owner and download all the drivers and the software I need, anyway.

  I see no major reason for dismay.

  A recovery partition is handy to have, but once you build the PC the way you want, use the included backup and imaging tools native to all versions of W7 and create your own recovery image on a drive hard portable usb.  Can use it if you need to recover the operating system.

• Black screen after startup probook 4520 s

  Hi all

  I just got the probook 4520 s a few months ago. Now, I have a problem: when I start the laptop first sign of hp and then the windows sign appears on the screen. Instead of asking me to log in using the password or fingerprint digital, the screen will become black and all I can see is the mouse. I tried ctrl + alt + delete, but which does nothing.
  I restarted my phone several times, but the same thing over and over again...
  Can someone help me please? I'm a little desperate and all stores are closed on Sunday in Germany.

  Hello

  Try the hard reset, but this time when you press the power button start to tap the F8 key to see if you can get into safe mode.

  If you can get into safe mode, then you should be able to do a system restore to an hour before the start of this issue.

• Mysterious black border (only) at the bottom of the first screen iPhone

  I have an iOS application that I wrote in 2011, and I'm trying to upgrade to the latest iOS and devices.  I have a thick black border at the bottom of the first screen of my request, for most combinations Device/Simulator and iOS. This is * not * a black border at the top and at the bottom of the screen problem, who has been treated exhaustively in the forums.

  There is only a single black border at the bottom of the screen. Also, the border is only broadcast on the first screen of my request, that has buttons to go to the rest of the application. Even if I navigate to the first screen of my request, somewhere inside the application, the border becomes visible. There is no black border in the other forms in the application, apart from the first screen.

  It is * not * seems to be a launch image problem. I have a picture of launch, [email protected], and the launch image works fine. Here are the setups I get or don't get the black border:

  iPhone 4S (iOS 9.2) Simulator - without black border

  iPhone 5 (iOS 9.2) simulator - black border

  iPhone 5 (iOS 8.1.3) device - without black border

  iPhone (iOS 9.2) 5s simulator - black border

  iPhone 5 s (iOS 9.1) peripheral border - black

  iPhone 6 sec more (iOS 9.2) Simulator - black border

  iPad 2 (iOS 9.2) Simulator - without black border

  iPad (iOS 9.2) air Simulator - no black border

  iPad 2 Air (iOS 9.2) Simulator - without black border

  Pro Simulator (iOS 9.2) iPad - thick black border all around the application window

  retina Simulator (iOS 9.2) iPad - without black border (at the bottom of the screen)

  I tried everything I could think of, but nothing seems to work.

• ProBook 4520 s - exchange of the wireless network card

  Hello everyone.

  I think the exchange of the wireless network card in my Probook 4520 s, due to the low flow.
  So I searched for a while a 5 Ghz supporting the card and found out that I am only able to get in the "white" cards list working. Then I looked at this page:

  http://h20000.www2.HP.com/bizsupport/TechSupport/document.jsp?lang=en & CC = US & objectid = c02487851 & jumpi...

  These cards can be any, that have been used in 4520 s. Mine (according to the Device Manager) is the Broadcom 4313 802.11b/g/n. This thing only supports 2.4 Ghz. Now, I looked at the list for a 5 Ghz supporting the card. I think that the 802.11A/B/G/N WLAN Intel HMC 572520-001 minicards can operate on 5 Ghz, because I read, that A appears only with maps of 2.4/5 Ghz. I read too, that maps of 2.4 / 5 GHz have 3 antennas, but on this card I only the slots for 2. Is this good? And this card would go into my 4520 s?

  Greetings,

  Colony

  Hi, colony:

  You are right about your statement about the cards being described as A/B/G/N dual-band.

  The best thing to do is look at Chapter 3 of your service manual.

  You can only order one of the cards listed as supported and it MUST have the HP reference on it or it won't work.

  I see only two possibilities for you...

  The 6200 Intel and Broadcom 4322.  Make sure you also get the part # that corresponds to what country you live.

  If your current Broadcom card has integrated Bluetooth, you will lose your Bluetooth capability if you order an integrated HP bluetooth module and probably the cable too.

  None of the dual-band cards have embedded bluetooth.

  Link to the service manual.

  http://bizsupport1.Austin.HP.com/BC/docs/support/SupportManual/c02439213/c02439213.PDF

  Then, you can order a card on the link below.

  If you do not live in the United States, you can change your country at the top of the page to yours.

• T43 will not move past the first screen

  My mother gave me this thinkpad because he had a virus (Windows shield Center) and he locked her out of her computer. She could always use Safe Mode, however. When I initially got tried to start, but he walls me an error message "missing hal.dll" and told me to reinstall windows, which I did not.

  I thought that this could be a fluke, but now the ThinkPad won't even go past the first screen that says "To interrupt normal startup, press the blue Access IBM button" without worrying if I press that key, or, the function keys.

  This is as far as I came. What are my next steps?

  This looks like a start of a failure of SouthBridge chips which is very common on these machines.

  Remove the keyboard (but keep that he attached), the palmrest and the wireless card.

  Turn on the machine, then * gently * press the big square under the slot wireless chip.

  If the machine starts normally whenever the square is pressed, a SouthBridge chip failure.

  Good luck.

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

  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.

• Replaces the Probook 4520 s HARD drive. Reinstalling Windows 7?

  The hard drive failed on my Probook 4520 s after only 18 months.  A Windows disc came with the computer?  If this is not the case, how to reinstall Windows when a HARD drive fails?  (I know not how to buy and install Windows, I'm more interested in how it is retrieved when it is stored on the failed rather than the removable media drive).

  The reason why I don't know if a disc that came with the computer is that we recently moved to a new State, and the disk can be in one of the boxes, still unopened.

  Thank you

  Patrick Mc.

  Good,

  This may solve your problem.

  If you have the product key for the version of windows 7 that was on your computer, you can go to: http://www.mydigitallife.info/download-windows-7-iso-official-32-bit-and-64-bit-direct-download-links/

  in which, in, you can download the appropriate windows 7 ISO (don't forget the version is the same as that which was previously installed on your computer). Burn the ISO to a disk and then install it from the disc & activate with your product key.

  I hope this helps!

• Startup problem: first black-wallpaper appears with the logo, and then the screen goes to the Microsoft screen with green moving bar "Please wait".

  My computer is having problems loading the main office. I start it up, the first black-wallpaper with the logo is displayed, then the screen goes to the Microsoft screen with the green bar of movement. After that, the Windows logo appears and makes the sound. A new screen will appear with a "start-up Fund" and he said: "Please wait...". "This form of lasting about 5 to 8 minutes, then the text disappears, with only the bottom upward. I left it sitting there on the blank screen for about 20 minutes, and still nothing changes. I tried Ctrl + Alt + Delete, and shows nothing. Finally restart manually, but the same problem occurs. The only way that this works is in Mode safe mode with networking (which is currently used). I also tried the system restore, but this does not work because by default it must go through the same problematic steps, as mentioned previously.

  Hi ninja_panda13,
   
  -Remember to make changes to your computer after that this problem started to happen?
   
  As you are able to boot mode safe mode with networking, put your computer in a clean boot state in order to verify if any third-party application is causing this problem.
   

  Put your boot system helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.
