Pavilion 500-046: fan runs loudly after BIOS update

So I downloaded the BIOS and sends an update notifications HP wireless. Consumer Desktoop PC BIOS update HP (family ROM SSID ZAEO). After the restart, the fan on my PC very strong rotates every 30 seconds or so for about 15 seconds then turns off; sometimes even more frequently. It's never happened before. Anyway I can fix this or go back to the old BIOS or something?

Then I opened my PC and went home with a feather duster and a vacuum. This ended the problem.

Thanks for your help Dave.

    Unfortunately, the first version of the BIOS can be installed by a technician of the ASP.

    But I wonder about the error messages that appear after the update of the BIOS.
    Have you tried to reinstall the OS from the recovery CD? You must test the laptop with the factory settings!

    By the way; access the BIOS and set the defaults. And don t forget to save changes ;)

    Try it please change the settings of cooling method.

  • TouchSmart HP Envy 15 - fan runs loudly

    This morning, I needed to recharge my phone. As the laptop has resided on the ground, I lifted one side of the laptop until you find the power plug-in and accidentally slipped my hand. The height of drop is about a foot or less. Then I booted up my laptop, it ran for a few seconds and turns off. I started again and this time it works correctly. However, the fan runs loudly and he will not stop until I turn off my laptop. I guess the bit is as strong as the 2nd level of the fan. Does that mean something is wrong with my hardware/driver? Help, please. Thank you.

    Hello

    ACPI-> Advanced Configuration and Power Interface
    ACPI defines hardware and software interfaces that allow focus on the OS configuration and power management to enumerate and configure motherboard devices.
    For example: ACPI is necessary for the standby and hibernation mode.

    Now your question; the new BIOS has been updated and configured to using VISTA.
    It seems that VISTA was not compatible with the previous version of BIOS because the ACPI interface. Now you can install Vista on the laptop, but it seems that you need a driver. Possibly new chipset driver version might help. But as you probably know, the drivers are not available at this time. Unfortunately

  • Pavilion 500-046: update BIOS on Pavilion 500

    Reviews of need for "HP consumer Desktoop PC BIOS Update (ROM family SSID ZAEO)." Downloaded the update, but when I tried to install, the screen went black for ten to fifteen minutes at that time, I panicked and shut down my computer. She started very well, but I am concerned about the update. Should I try again? Really should the screen be bleak for so long during the installation? It's VERY annoying. What can happen if I just don't install the update? My computer is a pavilion of 500, model 500-046.

    You are the very welcome.

    A doorstop, this is what your PC is only good for after it no longer works.

    I read a few posts from other members of the forum about the failure BIOS flashes after notification to support assistant.

    Maybe they are the same model as yours. They were recent messages last week.

    In any case, given that your PC works, I would leave it be.

    The fact that the update has been downloaded and is on your PC should be of no interest.

    It does not work by itself.  You have to find it in the folder of the file and double-click on and run the installer again.

    But if you get any more notifications of the wizard to support updates to the BIOS you can ignore them.

  • Satellite L750-A218 - fan run faster after 3.30 BIOS update

    Hello

    Here's a new show, I have am experiencing after the BIOS update.

    In my view, that the internal fans turn all the time by placing my hands near the keyboard. According to Toshiba software fan speed is 50% + while I do nothing. On the other hand, it is 25% before the update.

    They are updating the BIOS to give the laptop more ventilation or something.
    It's weird. CPU temperature is 45%. I upgraded from 3,00 to 3.30, for your information. Thank you.

    P.S. The speed of the fan is stuck at 50% + and wont go lower than that.

    What bothers me the most is that when I put my hands on the part at rest I feel the vibrations of the fans. I use the keyboard a lot and it is a huge nuisance. Is it possible to get the old BIOS, the BIOS updated not did me not a backup option. Also, I don't have a problem with the voice of fan (s). Its low.

    Edit: Just downgraded to 3.10. Its the same thing. Couldn't find the 3.00 version, I've had anywhere. It's frustrating.

  • Wake On Lan for Pavilion 500-046

    I have been using Wake On Lan on my other computers to wake up computers on my network that have been closed using the Windows 7 shutdown command. This is a very useful feature for me, and I would like to make it work on my computer HP Pavilion Desk Top with Qualcomm AR8161 PCI - E Gigabit Ethernet control. The Bios on the 500-046 has this option, and I put it to ACTIVATE. I am running Windows 8.1 update on the Pavilion. I, moreover, looked at other possible power in Device Manager settings, but I'm not having any luck getting it works. There is absolutely no response from the Pavilion when a wake on LAN signal is sent. A similar question has been posted by me a few days there are no answers. Maybe and Expert could give it a whirl. Thanks for any help.

    Hello fredkoch3,

    I read your post about how you have problems to wake on LAN issues with your desktop computer, and I'd be happy to guide you to a resolution!

    To start, I recommend that you follow this thread on ' Wake on LAN ' (WOL) behavior in Windows 8 and Windows 8.1. This should help explain how (WOL) is used for Windows compared to Windows 7 8.1.

    To find out if your system can be configured for Wake on Lan, I suggest a command "powercfg' running on your computer. This will check the power management features available. To do this, please follow the steps in the following procedure:

    1. Press and hold the Windows key and the R button simultaneously
    2. Type the word cmd in the box provided
    3. In the command prompt window, type the command "powercfg - availablesleepstates.
    4. Here you can compare the available sleep States using the document States supply system to see if (WOL) is available.

    Reference: http://msdn.Microsoft.com/en-us/library/Windows/desktop/aa373229.aspx

    Please re-post with the results of your troubleshooting, and I look forward to your response!

  • Satellite Pro P200-15W: after Bios Update 1.90 incredibly noisy fan

    Hi, I have a Toshiba Satellite Pro P200-15W, I recently made an update to BIOS version 1.9 and seems to have been a big mistake.
    After restarting the computer, I had a lot of software deconfig and the fan has become incredibly noisy.

    I have the problem with the Toshiba Vista registration software, I get this message: "registration of Vista has stopped working". I read other discussions, I don't want to just disable it in the start.ini file, I would actually solve the problem if there is a way.

    Is there a way to change the configuration of fans? I read a post from Toshiba on another model of laptop that has had the same problem of noisy fans after an update of the BIOS, they gave that a solution with a new version of the BIOS, is there a way to reverse the BIOS to the previous version? (recovery CD will be useful for this purpose)?

    See you soon

    Edgard

    Hello

    It seems that the picture of the fan was changed and renewed in the new version of BIOS, and so fans run fall.
    Why the table fan has been changed?

    Well, usually something like this is necessary to improve the reduction of the internal temperature while the CPU and GPU are running with maximum performance.
    This helps to prevent the equipment from damage!

    Usually, the recovery CD formats the whole HARD drive (partitions too) and installs only the image of Toshiba on the notebooks of HARD drive.
    The image contains the OS, drivers and additional software and has nothing to do with the BIOS update.
    But you can try to recover the laptop to see if you can solve the problems of software as "Vista record"!

    If you want to reverse the BIOS, you will need to contact the ASP in your country!

    Sorry, but all I can suggest.

    Best regards

    More recent versions of the UEFI suport Sapphire cards if it is stated in the specs on the website of the company. Perhaps you should consider returning and its replacement by a new PCIe card.

    Here is the list of specifications to Sapphire in the link below. Notice that most of the R9 series supports UEFI. There is no map of R7 series made my Sapphire Tech who take care of UEFI.

    Hi @STICKMAN5124,

    Nice day! Thank you for your participation in the Forums of HP Support! It is a great location to get resolutions and interact with experts from the community. It will be a pleasure to help you.

    I saw the post and understand that after only a bios updated cursor drops down due to a problem of scrolling.

    Impressive work, do the update of the bios. Kudos to you for this. It is a privilege to work with tech-savvy and technically competent customers like you and we greatly appreciate your business with HP. You have been great to work with.

    Please check in F2 diagnostics if the scrollbar works correctly. If Yes, then you can update the chipset drivers and http://hp.com/drivers touchpad drivers you can also consult with a mouse external further isolate the issue.

    You can also run diagnostics on the touchpad from this link by going to the UEFI F2 diagnostics: http://support.hp.com/in-en/document/c03467259 please run the complete components. If any component fails, please note the failure code. This is done to determine if the problem is hardware or software partners.

    If it passes and scrolling works very well, please perform these updates. If you are still having the same problem on page F2 UEFI (screen) then you could roll back bios after performing a hard reset. Link for the hard reset: http://support.hp.com/us-en/document/c01684768

    • Please perform this step to roll back bios.  Hold down the "Windows" key and the letter "B" at the same time, then press the power also button for about 5 seconds at the same time.

    I hope this helps. I would like to know how this happens. I hope the problem is solved without hassle and the unit works very well.
