• ProBook 6540 b: ProBook 6540 b BIOS locked

  I bought broke ProBook 6540 b for parts on eBay. Managed to fix the card mother, added a drive hard, but cannot open the BIOS to set the configuration.

  What can I do to unlock it? There is a service of HP that does this?

  I found a software on the Internet that does the job and costs about US $ 25, but since I have nothing to hide (for laptop is stolen not :-)) Ii hope there is the simpler and less expensive way to do it.)

• HP Probook 4520 s lost BIOS PASSWORD problem

  Hi guys!

  I can't remember my BIOS password and want to update my BIOS to the 2014 version. Asked me for the password that I can't remember it. Could someone please help...

  My Product Details:

  Laptop HP ProBook 4520 s
  Serial number: 2CE0410Z72

• 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)

  Thank you very much

  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 - dual boot between Win7 64 bit and Ubuntu 10

  Hello

  I just got my new HP ProBook 4520 s a few days ago and:

  (1) there were 32 bit Windows7 professional pre-installed / pre-loaded

  (2) it comes with the TWO 32-bit and 64-bit Windows7 professional DVD HP (I guess versions OEM HP)

  (3) the HD have 4 partitions in the following order

  score A 3 a) named SYSTEM

  3 (b) the parition where Win7 is installed

  (3 c) HP_RECOVERY partition

  partition HP_TOOLS 3D)

  I did a lot of dual-boot in the past years, but my question is really related to maintain the HP diagnostic tools that arise before even that any operating system is loaded... and diagnostic tools are those of the HP_TOOLS partition. For example, when I ran some diagnostic tests, after completing the tests and the boot of Win7, I see in the HP_TOOLS partition, in one of its directories, a .log file recently updated with the results of diagnostic tests. I want to assure you that I can still run powered on the laptop even after dual-boot diagnostic tools.

  Now, since I have the DVD 32 - bit and 64 - bit, I decided I want to dual-boot between Linux and 64 bit Windows7 professional. So here's what I've done so far:

  (A) has reduced the volume of Win7 Windows computer management disk management

  (B) install Win7 64 bit on top of the existing 32-bit Win7 partition, format this partition during the installation. So no more HP utility and on the installation of 64-bit programs.

  So now I have Win7 64 bit installed and professional pre-activated since it's the same notebook. Then, I realized that I really need to delete the HP_RECOVERY partition since you can have up to 4 primary partitions. So by deleting the HP_RECOVERY partition, I will be left with 3 primary partition, then I can create an extended partition to contain other partitions for Ubuntu, etc...

  But before I delete the HP_RECOVERY partition, I want to know:

  *) When starting, before even that any operating system is loaded, HP you shows options like "Diagnostics" and "recovery". How is the computer HP laptop knows that diagnoses are in the HP_TOOLS partition? How the laptop HP ProBook 4520 s knows that recovery is in the HP_RECOVERY partition?

  *) Since I have the DVD of Win7 HP (32-bit and 64-bit), I don't really have the HP_RECOVERY partition. If I delete the partition, what will happen to this start screen which gives you the possibility of "recovery"? Of course the recovery option won "t work and I don't like, but will remove the partition HP_RECOVERY won't let me boot into Win7, or any OS besides? for example it does not validate there HP_RECOVERY partition to a place before loading Win7?

  *) Then, I want to install Ubuntu, and preferably Ubuntu (or Grub also) overwrites the MBR. I prefer Grub on EasyBCD. I can easily change the configuration of grub so I can dual-boot with Windows7... But again, my question is, where does HP maintains information about diagnostic tools that they are in the HP_TOOLS partition, like the option of the diagnostic tool loading via BIOS before even any OS is loaded. Is that information in the MBR, or is it in the partition named SYSTEM?

  Summary of the questions are therefore:

  (1) where HP keeps its information that diagnostic tools are in the HP_TOOLS partition? It is in the MBR, or the SYSTEM partition, or is it stored in the BIOS hard coded to load more precisely from the location of the partition? I want to keep the ability to run Diagnostics even after you have a dual-boot installation with grub in the MBR.

  (2) deleting the HP_RECOVERY partition will prevent the workbook from loading correctly before moving to Win7, Ubuntu or any other OS?

  Just find the answer to my original question:

  http://h20000.www2.HP.com/BC/docs/support/SupportManual/c01564727/c01564727.PDF?JumpID=reg_R1002_USEN

  He uses the EFI interface and seeks a partition named HP_TOOLS, which means overwrite the MBR will not affect the operation of the HP diagnostic tools.

• ProBook 4520 s: upgrading my ProBook 4520 s

  Hey there dear community,

  I have been using my HP ProBook 4520 s for more than 5 years. It serves me well throughout my college and colleges after years so I decided to try to muscle it a little rather than change. My current system specs are (have it with Speccy):

  Operating system: Windows Pro 64-bit 10
  CPU: Intel Core i3 330M @ 2.13 GHz 61 ° C Arrandale 32nm technology
  RAM: 4.00 GB Dual - Channel DDR3 @ 532 MHz (7-7-7-20)
  Motherboard: Hewlett-Packard 1411 (CPU 1)
  Graphics card: monitor generic PnP (1366x768@60Hz)
  512MB ATI Mobility Radeon HD 4500 Series (HP)
  Storage: 1043GB Western Digital WDC WD1001X06X-00SJVT0 (SSD) 42 ° C Black2
  Optical drives: DTSOFT device CdRom virtual hp DVDRAM GT30L
  Audio: AMD High Definition Audio Device

  Now, I have done my share of reading and I reach two conclusions:

  -This laptop simply is not designed to work image or processors so my two options above are dual-core i5 or i7 CPU.

  From what I've read here and there, the most optimal processor that can be used on this particular device are the i7 - 640M, i7 - 620 M and i5 - 580 M. I understand that if I go with either of these three, productivity would increase with about 25-30%.

  -J' have already updated the 3 GB memory to 4 GB, but to my understanding of this laptop supports up to 8 GB of memory, so I'm considerring getting a 2 x 4 GB DDR3 PC3-10600 • CL = 9 • unbuffered NON - ECC DDR3 - 1333 • 1.5V 512Meg x 64 kit SDRAM SO-DIMM 204-PIN.

  My storage is pretty much the best thing to get for this laptop (there the SATA2 port (3 Gbps)) a full 1 TB SSD would be a bit pointless.

  My questions are:

  -Are there problems or other things to consider about the possible CPU upgrade? I would love to see a video tutorial on how properly to the replacement

  -Am I missing something with the memory upgrade? I'm a little hesitant on that tensions must be on the memory sticks (1.35v or 1.5V).

  -Are there else I can do for this in order to make a little more current (drive optical swap with something else, etc..)?

  I really appreciate every suggestion and comment.

  Thank you!

  Cap

  I7 - 640 M is the top processor of the page. Memory DDR3-1066 and is 1.5 volt. The most recent memory of 1.35 volts to the DDR3-1600 not will probably support. HP recommends this:

  4 GB (PC3-10600 1333 MHz, DDR3) 599092-001

  http://www.Amazon.com/HP-DDR3-SDRAM-memory-module/DP/B0030L3B8E/ref=sr_1_1?ie=UTF8&QID=1438431520&SR=8-1&keywords=599092-001

  Your repair manuals

  YouTube video

  Technology in the video does not actually remove the CPU but it shows. Remove the processor carefully by turning the locking screw for "open" and lift the CPU out. Be extremely careful with the pins. The new line backup the same orientation as the old and drop it in. Just be sure to block the processor setscrew down tight when you go back. You must follow the instructions on the installation of thermal paste and cleaning.

  You can also consider a SSD drive. The gains to be achieved will be more sensitive than the CPU or memory. Also keep an eye on what you spend and make sure it makes sense. If I could only do an upgrade, it would be the SSD. I would like to bother with a Blu - Ray player on a laptop.

• HP ProBook 4520 s USB 3.0

  Hello

  I only have HP ProBook 4520 s with USB 2.0. Must be made some BIOS upgrade if I want to add USB 3.0 Express Card 34, or it will not work properly?

  No BIOS upgrade is needed. You will need a driver. I guess you have to least Windows7. A driver disc will probably come with the unit.

• 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.

• 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.

  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:

  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?

  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.

  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 s: lack of features on a ProBook 4520 s after upgrade Windows 10

  Hello dear community

  Long story short: I have a HP ProBook 4520 s and yesterday I upgraded manually (with the tool provided by MS) Windows 7 Pro to Windows 10 Pro. Everything went very well and smooth and it works perfectly well until now.

  The problem is that some of the features of the laptop no longer work. Here are some examples:

  -Highlight the option on touchpad

  -built-in camera

  -Some FN buttons like the one for the brightness of the screen while others (for example, the volume and email) working

  My reasoning is that it lacks certain drivers or these functions are somehwat is not compatible with the new OS (it's a 5 + year old PC after all), but I could be wrong. I'd like to hear some suggestions and opinions on this.

  If someone needs to my specifications complete, there are:

  Operating system: Windows Pro 64-bit 10
  CPU: Intel Core i3 330M @ 2.13 GHz 61 ° C Arrandale 32nm technology
  RAM: 4.00 GB Dual - Channel DDR3 @ 532 MHz (7-7-7-20)
  Motherboard: Hewlett-Packard 1411 (CPU 1)
  Graphics card: monitor generic PnP (1366x768@60Hz)
  512MB ATI Mobility Radeon HD 4500 Series (HP)
  Storage: 1043GB Western Digital WDC WD1001X06X-00SJVT0 (SSD) 42 ° C Black2
  Optical drives: DTSOFT device CdRom virtual hp DVDRAM GT30L
  Audio: AMD High Definition Audio Device

  Thank you for reading. All the tips and comments are appreciated.

  Hello

• HP ProBook 4520 s Notebook PC - CPU upgrade

  Product: HP ProBook 4520 s Notebook PC
  OS: Windows 7 64-bit
  
  HELO,
  
  I want to upgrade the CPU on my laptop. It comes with "Intel i5 m460" - 2 carrots. Is it possible to replace it with a 4 core CPU for example "processor Intel Core i7-720QM Mobile" or "Intel Core i7-740QM Mobile processor"? Is there a rule of thumb to check what CPU can be updated and with which we? What would be the best equipped (to the family of the i7 - 4 cores) CPU update for my situation?
  
  Many thanks in advance,
  Tom

  Unfortunately, the answer to this question is no.
  
  The best compatible optional processor is the Intel Core i7-640 M and has two physical cores can run four threads.

  Best regards
