Thanks in advance!

    HP Pavilion p101nq-15 Notebook bios password forgotten

    System off and get [51183616]

    Hello

    In this case, check the following points.

    1 stop (generated after 3 erroneous seizures) code that you posted is correct.

    2. turn off the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Plug the power adapter (leave the battery for now), start Notepad and try entering the code from my previous post again.

    3. try to enter the code via a keyboard external usb.

  • Pavilion 1226nr: need bios password recovery

    I just bought a refurbished 17 laptop computer 1226nr HP pavilion with a bios password hashing is (D567ADAF) Please help

    Hello

    Your laptop is to produce a code hexadecimal halt which is stored in the ram as a 'one stop' and is recalculated after a reboot.  This indicates that you have a FRIEND bios later and unfortunately none of the current code generators will work - surprisingly, you can usually always remove power on password of the machine by removing the cell RTC (leave the connected Power Board) then hold down the power button for 60 seconds before reinserting the RTC.

    The bad news is that the RTC is on the 'wrong' side of the motherboard so is going to require a lot of disassembly - see Page 92 of your Maintenance & Service Guide.

  • Pavilion DV7-3060us: BIOS restore file "not a win32 application invalid" (Pavilion DV7)

    I have an intermittent (about 19 times out of 20) on a Pavilion DV7-3060us BIOS failure.  After that you press power, the fan and the light turns on, the screen remains black and lock/num lock flashing twice, pause, flash twice, etc..  Sometimes, the computer will boot normally to Win7.   Near as I can understand, I need to reflash the BIOS.  I downloaded the image file winflash/BIOS (SP47531.exe) the drivers and software page, but when I try to run it, I get a "...". not a Win32 valid request"message.

    Any advice on how to get this file to run it, or another method to solve the failure of startup issue, would be very much appreciated.

    So much worse... apparently the problem is I downloaded the file through Chrome.  Downloaded with IE on another machine, recorded on a USB key, it connected the USB on the machine of problem without difficulty.  Does not seem to have solved my problem starting, but the 'valid not a Win32 application' error has been resolved.

    When I get 3 wrong passwords, it gives off system error and a number written below 52856771.

    Any help would be appreciated.

  • Administrator Bios password does not work on HP 4420 s XT940UT #ABA Windows 7 64-bit

    Someone please help me with this!

    I bought this laptop from a friend (have receipt) who sell it to me because the screen was cracked and spidered all out when you the activated. And everywhere he went to ask to get the screen fixed it is very expensive ($250 - $350) and he said that it would be just a newer laptop. So he sold me this which is a model Probook of HP4420s XT940UT #ABA. About a week after I bought this Probook friend who sold it to died me suddenly. It was sudden and terrible. Some time later, I had the time of the purchase of the LCD for this model, replace it myself (was very easy actually) and booted up the laptop with a new installation of Windows 7 Professional 64-bit Edition. After installing all my software and using the laptop for a while now, I wanted to get into the Bios that I've never done. So when I started the laptop, click ESC, then F10 to enter the BIOS, there were two places to enter a password is different then all Dell I've ever owned. One was mine I guees I put in place using HP protect tools and the other says BIOS/administrator. Well I can do most of the changes with the one I put in place with my password but my password does not work, nor can I get in some very significant changes that I wanted to do using Bios/administrator, as kindling the LoJack, namely the blocking of the hard drive etc. , turning on turbo boost, fan, etc. Well, since the person I bought is no longer with us, there is no one to turn to the answer to this question of administrator/BIOS password / problem.  I tried to take battery Rtype and restore that way, didn't work. Several times, I called HP and they sent me to a BIOS page to download the same BIOS, I have already, would not let me install it. When I bring up the command prompt and do not put anything in BiosConfigureUtility.exe happens, said just a wrong command. When I try to enter the BIOS through the C: file in the files of the SSM, I reach the BiosConfigUtility.exe file, click on it to open it and it just flashes a way small order page to fast to read what it says. I would like to have complete control over my laptop thinking I have a lot of time and money invested in it now. The problem would have something to do with installing the 64 bit version of Windows 7 instead of the 32 bits I suppose initially that he came with? I have all the manuals and they say that this laptop is compatible with Windows 7 Ultimate 64 bit Pro is what I installed. I'm mixed responses from many different people on this and would like an answer from HP someone who has experience in dealing with the BIOS in the Probooks business models if possible please. I really like this Probook and have since become big fan of most HP, Dell and Lenovo.  I intend to buy two probooks, one for my wife and one for my daughter because this one is like a MacBook, but better.  Thank you for reading this and I hope someone can help.

    Model: HP Probook 4420 s

    Type: XT940UT #ABA

    Operating system: Windows 7 Ultimate

    BIOS version: 68AHHH Ver.F.20

    SM BIOS Version: 2.6

    Hardware Extraction layer: Version 6.1.7601.17514

    Once you open a session with the service the customer of HP one case of pension, they will provide once the utility you and steps to execute it. who can capture the UUID. BTW - UUID is a unique ID for each machine (16 digits or more) stored in the BIOS itself.

    Once the results of the utility (UUID and other info) in the log file, shared with HP, they can generate a key file (SMC) to reset.

    Well, depertment of technical support can help you in it, no need to ask for anyone in particular or the Department.

    It will be useful.
