• HP Probook 4520 s running extremely slow

  Hello

  recently my laptop have been slow (almost at a standstill). I suspected at first, it was a virus, but a test of the virus found nothing. So, I formatted my OS partition and installed Windows 7 Professional and that the essential software that I use. After a short time (1 day), he started running slow. among other things, I freed disk space, but it did not help.

  Then I ran the BIOS boot and test drive, and both returned "error: read failureError: failed to read.
  Help, please.

  Record everything you keep on an external hard drive. You have discovered why she was slowing down. Your hard drive has failed and needs to be replaced.

  The BIOS hard drive Diagnostics is an excellent utility for troubleshooting.

  If your Probook 4520 is still under warranty, contact HP for a replacement hard drive.

  If is no longer in warranty, it's time to buy a replacement hard drive. Once you have installed the new break of hard disk on the set of recovery disks or USB recovery media that you have made.

  Your Probook 4520 s uses a SATA hard drive 9.5 mm, 6.35 cm (2, 50-in). I do not recommend using a SATA3 drive for possible compatibility issues.

  A SATA or SATA2 SSD also works and will be a performance gain true if you choose to go this route.

  When I installed the memory module on the laptop, I couldn't go essentially exceed the stage of the POST. Is the HP logo appears on the screen and what is it... That's all... nothing beyond this point.

  When I went to the BIOS settings, memory read 81xxMB successfully, it is essentially 8 GB of RAM.

  I tried to reset the BIOS settings, has not yet.

  I removed the 2 x 4 GB modules, put back the two original modules of 1 GB and 2 GB - those who came with the laptop-, everything worked again.

  What was not right here... ?

  PS please don't answer not with lame answers "it's weird", "that's strange", I know it's weird and strange. I want clear and specific suggestions.

• ProBook 4520 s: updates to driver for all components

  Salvation; I read the posts on the update of the drivers on the ProBook 4520 s and I do not understand that we should select the most recent drivers from the drop-down list under EACH item listed.  I'm still a bit confused, however.  Some components have several drivers listed under them, some of which have different names/Descriptions.  I need to know WHICH of these "components named" is installed on my ProBook?  Alternatively, they are ALL different names in EACH of the installed components?  I'm afraid to install the wrong drivers if I select just the most recent review date, irrespective of the name/description.  I have had my ProBook 4520 s about 5 years and NEVER updated ALL drivers (that I can remember).  I am running Windows 7 Professional, 64-bit with the Intel Core i5 460 M/2.53 GHz Quad Core processor, a 320 GB Serial ATA-300, 7200 RPM hard drive and a HD Graphics Dynamic video memory technology Intel graphics controller, etc., etc.  The problems I encounter are: it is slow to start, it delayed opening opening sites & programs & there is a power outage occasional temporary graphics (gel?).  So, at the very least, I think that my graphic card driver needs to be updated.  But surely most other pilots must update as well.  (And Internet HP site lists a ton of drivers when I plug my ProBook.  I use my laptop every day and have not had a major problem.  I recently had to update the drivers on my HP printer, and even if the printer is NOW printing again, I ALWAYS shows an error on the ProBook (when I go in devices & printer from the control panel), on the Officejet Pro 8600 Plus e-all-in-one. As the error message did not disappear after I solved the printing problem, I think it's probably a good idea to update ALL the drivers in my ProBook before I start to experience more problems... Is someone can you PLEASE help me understand WHAT drivers should I install and in WHAT order, so I do not screw up my ProBook?  Thank you very much!  I appreciate all help.

  Go to the Device Manager in Control Panel, check the names of the devices under each category. Download the latest version of the one you want from the HP support page depending on the installed 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.

  Best regards

• Will be my laptop from inside my warranty boid clening? (hp probook 4520)

  Hi all

  I have a hp probook 4520 for a year and a half now. Where I live there is dust everywhere make my laptop sale. I regularly clean my laptop but I'm afraid to clean it from the inside because of the warranty. The laptop could even reach 90 degrees then in the hot summer days while playing heavy games. The guarantee expires next February, but will open my laptop and my fan cleaning void my warranty?

  Thanks for your time

  Hello:

  Yes, if you go too far in dismantling, will void you the warranty.

  As a general rule, any screw Philips removed do not void the warranty.

  The fact of any removed Torx screws.

  Remove the battery and the power of a/c.

  Put a toothpick in the scale of the fan and slide it between two of the fan blades, so they do not rotate. In spinning the fan will be destroy bearings.

  Then just use a can of compressed air and blow into the fan making to erase what you can.  You can even kick in the exhaust vents too and then again through the consumption of the fan until you see no more than dust blow.

  That should improve the cooling a bit.

• 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.

• eSATA / USB2 combo Harbour on HP ProBook 4520 s

  The ProBook 4520 s has an eSATA / port combined USB. What I want to know is:

  (1) is actually an eSATAp (power by ESATA) port?

  http://en.Wikipedia.org/wiki/ESATAp

  If not, how does an eSATA / USB combination port differ an eSATAp port?

  (2) I have a drive HARD 2.5 and a different SSD 2.5 since a laptop previous, I want to use thanks to an external box ESATA 2.5.

  If the port is an eSATAp interface, so I can use this:

  http://www.DeLOCK.com/Produkte/Gruppen/GEH%C3%A4use/Delock_25_External_enclosure_SATA_HDD_Power_Over...

  Unfortunately, I couldn't find one that sells the foregoing locally in Australia, so I might end up the use of this:

  http://www.Welland.com.tw/HTML/enclosure/940.html

  If I use the Welland, then I guess I can power the external case via the USB port of the laptop... but there must be a different USB port than eSATA / USB port?

  Thank you

  I ended up buying:

  http://www.Welland.com.tw/HTML/docking/601j.html

  and

  http://www.Welland.com.tw/HTML/poweresata/SCE200.htm

  Both worked out of the box with a 2.5 "SATA HDD and SSD.

  In fact, I'd just bought the CPE - 200, much cheaper, and the power is from eSATA / port combined USB. It IS therefore an eSATAp.

  NOTE: I do not have a 3.5 "SATA HDD to try the CPE-200 with, so a SATA 3.5 '' HARD disk may not work with SCE-200 alone, as I read reports that the power coming out of eSATA / combined USB port is not sufficient to drive a HARD SATA 3.5".

  Unfortunately, business machines such as Probooks or EliteBook have more strict security consumption patterns - they do not produce "stop codes", the password cannot be derived from the serial number and the code is stored in a nonvolatile memory to remove the RTC cell does not reset the password in this case.

  If you Contact HP Business support they should be able to send you a file custom SMC.bin that you can use to reset the password at startup.

• 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.

• ProBook 4520 button woes right touchpad

  Hi all.

  Got a new HP's Probook 4520 using XP SP3. I noticed that the touchpad is not what it should be in some windows.

  For example. If I open an Excel spreadsheet and right-click on one of the tabs at the bottom nothing happens. That is to say I don't get the submenu where can I change the colors of the tab etc.  With IE8 if I right click on open tabs by using the touchpad I get nothing. With the help of a mouse, I get the normal submenu. However if I right click using the touch pad on the desktop I get the right menu so I know that the equipment works. Strange problem, but it's very irritating. I had a glance through the different touchpad options (there are a lot!) but I can't find anything in this regard.

  Any help would be appreciated.

  Thank you

  Sammy

  Hi again.

  Just to let you know that if I press "Alt" then the button right then disappeared, the menus appear normal.

  Hope that this 'correction' helps someone.

• HP ProBook 4520 s problems

  Hello

  I recently installed windows XP on my ProBook 4520 s, and I have a problem with my network controller. I can't find the driver for it, even you I've tried a few, but they did not work and I can't connect to the internet.

  Can you please give me a list of software that I install on my laptop? I know that they are in the tab support & driver but I don't really know which is useful or not for my windows XP.

  My product and serial number are: WK511EA #ABB (the product) and {removed privacy} (series)

  Hello:

  The device that you posted is your HP Bluetooth module:

  This driver and software should take care of this.

  http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=321957&prodSeriesId=4145198&prodNameId=4145326&swEnvOID=1093&swLang=13&mode=2&taskId=135&swItem=ob-80152-1

  What is the string of letters and numbers of your wired network card device ID?  It appears in Device Manager?  If this isn't the case, you must go into your BIOS and in device configuration menu, make sure that your LAN controller is enabled. If this is the case, then set the LAN/WLAN switching for people with reduced mobility if it is set to active.

  You must save the settings, where you changed by pressing the F10 key and exit the BIOS.

• HP ProBook 4520 s wirelless card

  Hello

  I have a HP Probook 4520 s for about 4 years. My problem is that my wirelless card has stopped working. I tried to reinstall the drivers for this card, reset, but it didn't. A computer guy told me, this problem is in wirelless card, I need a new. It is SPARE HP 602992-001 WiFi card. I'm looking for a new on the internet and I read, this new card must be in the white list for my model. I founs some cards on ebay, but I don't know what they will be working. Can you help me, when I should looking for a new or who can I buy instead of this one?

  I'm running on Windows 8.1.

  I'm looking forward to your reply.

  Here you go for an exact replacement:

  Yours is a wi - fi network and bluetooth module, so if you want to replace double you another module. 4520 s used several types of cards. They are listed in pages 70-73 repair here:

  Manual

  It is another option for you:

  WiFi 802.11b/g/n 1 x 1 Broadcom 4313 and 2070 Bluetooth 2.1 + EDR Combo adapter

  Read the instructions carefully for instructions on replacing the card. It's a bit more involved on this model. Do not know why the Ralink is more expensive than the Broadcom; personally, I prefer the Broadcom. If you replace the Broadcom module you load new wifi and Bluetooth drivers. Here are the Win7 drivers:

  HP did not post drivers Windows 8.1 for this model, but it is likely to have the drivers to load automatically for the bluetooth and wifi Broadcom.
