A problem with the BIOS Probook s 4540!

I 4540 probook s laptop, two days ago, I updated the BIOS. I downloaded the BIOS from http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=5269095&... After that, I could not turn on my laptop. He just had white screen and Caplock light flashes 3 times. Can you help me!!!

Have you tried a RAM module in each slot or was used both slots at the same time?

RAM problems can be with the RAM itself or the RAM slots on the motherboard.

In case the POST test is false, although rare, you can try to restore the BIOS by following the steps in this document.

You will need to download Support UEFI environment to create the USB stick recovery.  It can be found here.

Let me know what happens.

  • HP pavilion n242se 15: problem with the BIOS software

    Hello
    I have HP pavilion 15-n242se and I have the problem with the software of the BIOS, because when I restart the computer it turns off completely and go back a few seconds later.

    Sorry for the bad news, but HP does not update the BIOS of your PC for Windows-10.

    They planned them to Win8.1, and you should have to do the upgrades at the time, BEFORE you upgraded to Win10.

    The HP BIOS upgrades are OS-specific version, so now that you have upgraded, you can no longer run these.

  • Problem with the BIOS of the Pavilion dm4-3002sa bought in Belgium

    5 months ago I bought a Pavilion dm4-3002sa (English version) in Belgium, where I live (to have a QWERTY, AZERTY keyboard like most laptops sold in Belgium). I discover now that this particular model is not recognized on the Belgian support HP web site - I could only find it on the web pages of HP UK.

    A month ago I started having repeated problems (automatic stop & restart every 3-5 minutes), which indicates there is a serious problem with my BIOS. The test of memory fails.

    I contacted HP support Belgian and send the laptop for repair (they said that they will replace the current memory).

    HOWEVER, I have another question: If the problem is caused by an incompatibility possible download relative to the BIOS here in Belgium, while my HP laptop is clearly a UK version and not recognized as a model sold in Belgium?

    If so, this means I can continue to have the same problem even after service.

    Registration of the laptop as based in the United Kingdom would be a solution? (i.e. regardless of my address of residence...) So that the updates & downloads are fully compatible with this model?

    A big thank you to the one who can help me!

    The problem of restart is much more likely to be associated, in view of the results of the test of the memory of the memory. You should have asked to send remembrance to you, rather than send the laptop away. Memory modules can be customer replaced. It is quite easy to do.

    The only real difference between having a QWERTY keypad and a QWERTY keyboard is the way the operating system sees the way in which the keyboard as being mapped when you choose the keyboard layout.

    Your computer laptop dm4-3002sa is still a laptop HP Pavilion Beats Edition entertainment as well as the USA (United States (version.

  • URGENT! problem with the bios to start the computer

    Hello

    I have a lenovo s12 notebook and I have the problem with the password of the bios. the bios was previously password protected and I wanted to get rid of it, so I opened the bios went in password management and tried to 'turn off' but apparently the system would not accept that option, while i went to the password field, then put the old password, and then I gave him 2 "drafts" enter enter since I assumed he wouldn't ask Word of past again... on windows it works like that, you put a blank password twice, and then it will not ask password again.

    now it's happened, it's that the system always ask the password on the bios, I can not enter setup again because the old password does not work after installing brief loading, it accepts either a blank password, I tried the generic password for phoenix bios which seems to be "phoenix"...

    should I don't have to go the hard way, open the computer and remove the cmos battery? Since it is possible to find it of course, since it is a laptop? does anyone know any other bios password "generic"? or I have seen that if you can build an external device then you can connect to the mobo and read the stored password on the mobo, but it starts to become a little too testy, I don't want to build and solder.

    Anyway any help greatly appreciated please reply to my email xxxxxxxxx

    Thank you very much

    Hi an welcome to Lenovo forum... Sorry... Here, there is a page for password lost or forgotten help Lenovo.

    If the password that you have forgotten/badly entered or other cases... is not one that can be reset, your options are to remember the password or get the motherboard & and/or replaced hard drive.

    I have tryied to get out a map of Moser for 24 hours battery - but it did not help.

    Could you help me please with this problem?
    What can I do?

    BTW, I can't get into the BIOS Setup and select the source of loading (Hard, FD or CD) because I have to enter a password first.

    Thank you very much!

    Hey,.

    Unfortunately, I don't think that an authorized service provider can help you get rid of the password because they have special tools to do and how to do it. Maybe some jumpers must be defined, but I put t know

    On the Toshiba Web site, you can find a list of aspic call them and ask for help, all that s! ;)

I noticed the image of the characteristic changing BIOS boot and creates the Logo.Mod file that I have included in my BIOS flash. However, flashing it, I noticed that the Intel Logo (top-right) and the Lenovo Logo (right & Vertical) still exists and overlapped my custom image.

    Is it possible to remove these logos so that I can have a clean design beautiful original appears at startup? I tried flashing back to nothing does not.

  • Problem with the HP Pavilion e033tx-15 Notebook shutdown/restart/sleep

    I had windows 8 OS 64-bit working fine with my HP Pavilion Notebook 15-e033tx.

    I had problems, so I decided to update my drivers. I already had BIOS VersionF.08 and the hp support page has shown that there is an update of the bios to VersionF.21.

    After updating the bios the problem started when I stop lighting and the laptop into sleep mode kindof. I have to hold the switch down to foce him close. If I restart it, it says "reboot pc", goes blank and then all power off, and it's not stopped.  and if I SLEEP, he's not waking up.

    I rolled back the bios and it fixed the issue.

    Then I freshly installed win pro 8.1, and it has only VersionF.21 of the bios available.  Same problem again.

    HP Support Assistant showed that a new bios update Insyde F.22. But the problem is still there.

    I searched other posts with similar problem and I can't seem to solve this problem. Help, please.

    Henrico Hello and welcome on the HP Forum!

    I understand that you have a problem with the BIOS.  I'll try my best to help you solve this problem. I suggest following the procedure described in this document for the restoration of the BIOS .

    If this does not resolve this problem then restores the version F.08 http://support.hp.com/us-en/document/c02693833 driver it should always work for Windows 8.1.  Here is a document for more information of the device to Windows 8 Manager which explains how to roll back the driver. It will be the same steps for Windows 8.1.

    I suggest Using HP Support Assistant (Windows 8) to change your settings for manual update. This allows you to choose what you want updates.

    I hope that this information help, please let me know how it goes.

    Thank you and have a great day!

We're spontaneous deactivation of a Wi - Fi connection, even if the Wi - Fi network works correctly (currently, a Tablet and a work of smart phones over wi - fi). And poor quality. Even being near the place of distribution, there are problems with the wireless network. Another question is why the laptop is not catch wifi 5 GHz (on configured router)?

  • 4320 proBook s - problems with the wireless Assistant

    Hello

    I have my ProBook s 4320 for about half a year now. For most of the year the half I had problems with the wireless assistant - it seems that when I start my laptop it takes about 5 to 10 minutes before the work of the internet. I never changed any settings in the wireless assistant.

    Nobody does face these same questions and no one knows how the internet starts immediately when I start my laptop? I tried this on different places with different wireless modems, but everywhere, it's the same thing and books of other people can use internet immediately.

    Thanks in advance

    Hello

    You are welcome to help

    The fact that it connects properly in Mode safe indicates that the driver who normally starts with Windows or a program is causing the problem - most likely candidate is to begin by F-Secure.

    Before attempting the following procedure, make sure that you have an installation of F-Secure program, so you can re - install this software, and also a license key necessary to activate it.

    Then, from the windows control panel. Open programs and features, click on the entry for F-Secure once to highlight, and then click the option to uninstall at the top of the window.  Once done, restart the laptop.

    Again, when windows restarts, check the internet connection by using only a known secure site.

    Let me know how this affects the problem.

    Kind regards

  • Problem with the software Modem on Satellite Pro L40

    I tried to set up a connection Dial-Up Networking on a Satellite Pro L40 running Vista and can't get the modem to talk to the modem from the ISP. The connection appears OK and then you can hear the modem dial, but when the ISP picks up there is a bit of yelling and then my modem abandons the connection and I get the standard vista connection failed box.

    Things I've tried:
    -latest drivers for the 2.1.77.0 modem (and the rest of the system) downloaded from Toshiba and installed OK
    -all the updates of windows installed
    -removal of the modem in the Manager of peripherals and re - install
    -suppression of the agrsmdel.exe and then re-install
    -try different cables to plug into the phone jack
    -several different ISPS and phone numbers
    -reduce the maximum speed of the connection
    -connection to the same ISP with my Satellite L10; works very well never have time!
    -using the windows to diagnose and repair the tool (set last resort!); says that the modem works fine and can not find a problem with the connection

    Is it possible that the update of the BIOS on the laptop would make a difference (currently v 1.60)? I did some research on Google and found messages on various forums, which suggests that the connection between the motherboard and the modem chip is a little doubtful for all the Agere Soft Modem; If the case is it something I can fix myself or I should go for warranty repair?

    Midders

    Hello

    I'm sure that there is no problem with your modem, but with the configuration or even s ISP modem. I recommend you to speak with the support of the ISP.

  • Satellite U500-17F: problems with the new HARD drive

    Hi everyone, I got some troubleshooting with my Satellite and a new drive, I bought recently, because that is already damaged because of too many bad sectors. One is a Western Digital Scorpio Black 320 Bg (WD3200BEKT model number). It should be a fast reader but is not with my Satellite.

    After having mounted the drive in the laptop, I ran a new installation (with full disk format} Windows 7 (64 bit) with all the necessary drivers (that I downloaded directly from the Page of Support Toshiba.)

    The problem is that the laptop needs a lot of time to start and also to disable, and whenever I try to run an application or start a program (for example Firefox, or just a few windows applications), the laptop freezes for about 30 to 60 seconds, the drive no longer works (you can hear leaders put in position 'parking' and the HDD LED control is constant) ", no lights flashing).

    It seems that the drive (during this 30-60 seconds) in something as a stand-by mode. I ran a few Western Digital diagnostic tools and the car looks all right to 100%. It works also without any problems in the other laptop (HP Pavilion DV6500). Could this be a problem with the controller (Intel ICH9M - E ATA AHCI controller) driver?

    Any suggestion?
    Thanx

    Hello

    You use the latest version of the BIOS?
    Please check if you need a BIOS update. Of course I read in a few discussions on the similar question of Win XP you use Win 7 but its value to check the update of the BIOS and U500 series.

    In addition, I recommend check you the power of Windows 7 options.
    Disable in the power profile that you use power saving HDD.

    Just a question:
    You use the option AHCI in the BIOS?
    As far as I know it of possible to use either a compatible SATA AHCI mode.
    AHCI must be used because this option would use full SATA performance.
