• HP Pavilion 15 laptop: Cannot install the driver/adapter wifi

  Hello, my wifi card has had a history of problems before now, I had to reset it frequently that I lost the connection easily. Today, I had to start questions so I did a hard reset on my computer. Then I realized the wifi adapter "disappeared" networks and sharing centre and I could not connect to any wifi. Broadcom wireless adapter was also hidden in Device Manager. I then uninstalled and tried to reinstall the card using HP Recovery Manager but the Device Manager I don't see anything installed. Installation on the HP site can also get nothing. I'm not sure if the Broadcom adapter is the problem at my misfortunes of wifi.

  

  That's what I see in the Device Manager. Thanks in advance!

  Hello
  Maybe this can help.

  Win7 when configured on the peer-to-peer network has three types of configurations of sharing.

  Group residential network = only works between Win 7 computers. This type of configuration, it is very easy to entry level users to start sharing network.

  Working network = fundamentally similar to previous methods of sharing that allow you to control what, how and to whom the records would be shared with.
  
  Public share = network Public (as Internet Café) in order to reduce security risks.

  For the best newspaper of the results of each computer screen system and together all computers on a network of the same name, while each computer has its own unique name.

  Make sure that the software firewall on each computer allows free local traffic. If you use 3rd party Firewall on, Vista/XP Firewall Native should be disabled, and the active firewall has adjusted to your network numbers IP on what is sometimes called the Zone of confidence (see part 3 firewall instructions

  General example, http://www.ezlan.net/faq.html#trusted
  Please note that some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible, configure the firewall correctly or completely uninstall to allow a clean flow of local network traffic. If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

• My HP Pavilion dv9720Ous laptop cannot connect to internet

  I installed a new Buffalo-G-CBOA router for home. My HP Pavilion dv9720Ous laptop connects to the router, but the HP laptop cannot connect to internet. Is there something that needs happeon on the PC to connect to the internet? Thank you

  How are you communicating on this forum?

  I suppose that from another PC, correct?

  Download you the driver on the PC that you are using, and you glitches the file on a CD, or copy on a USB key.

  You transfer the driver file that you copied to a flash drive or a CD into the computer that needs the update of the driver, then run.

  I've just updated the vCenter Server from 5.5U1 to 5.5U2b. In 'Health Service', there are new warning message:

  "Cannot control the use of database storage. See VMware KB 2078305 for more details".

  I use MS SQL 2008 R2 SP1 Express, which is supported by this version of vCenter. There are also a lot of free space on the disk of the server (63 GB free). Ko 2078305 does not explain this particular warning message and the data of events for task and retention policy are also defined.

• Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.

  Hello

  I recently rebooted my computer; (Packard Bell) and now cannot run games or screen savers because it does not start. I think my problem has something to do with a Direct3D card? When I run screensavers, I get this message:

  Cannot run the screen saver because it requires a newer video card or one that is compataible with Direct3D.

  I have the impression that sound when I run the 3D games, such as minecraft or GMOD.

  I run on Windows Vista Edition Home Premium and does not do anything but re - install my computer because it wouldn't start.

  It is not as if the graphics card is not there, so I'm really confused!

  Please help me, like playing games is my favorite thing. ;)

  I also ran minecraft to double check and I got this error code:

  Bad video card drivers!

  -----------------------

  Minecraft could not start because it did not find an accelerated OpenGL mode.

  Generally, this can be corrected by updating the video card drivers.

  > When I closed the lid

  The laptop goes into hibernation or standby mode once the lid has been closed or just the screen turns off?

  I'm not quite sure if its really a problem of display driver.
  Other FN keys work correctly?

  It seems that the C855-1CH Satellite was sold without any preinstalled system and looks that you have installed the Win 7 64 bit in your own hand.
  Were all Win 7 drivers as properly installed VAP?

  What is the BIOS? Is up to date? If this is not the case, try to update.

• Satellite A135-S4467 cannot control the brightness of the screen

  My screen is really weak and I can't adjust the brightness.
  I have XP here, all the latest drivers.

  A suggestion on how to clear the air!

  Hello

  The brightness of the screen is usually set at a higher level, also if the FN buttons do not work because of the missing driver or utility _ALWAYS_!

  That's why I put t understand why you screen is small.
  Check the screen brightness with preinstalled Vista operating system?

  Before you install other OS like Win XP, you should check that the brightness of the screen has been set at a higher level.

  PS: it could be also a hardware fault as a malfunction of the FL inverter and, therefore, it of really necessary that you check what current functional full Vista OS!

• You cannot change the screen brightness once I downloaded 8.1

  Hi all, I have a Pavilion Touchsmart and a 23 inch model, I've purhased in August of this year.  It was great to work with Windows 8.0.  Well, two days ago, I had the brilliant idea to update to 8.1, which was a big mistake.  The brightness was full and he says 'off '.  There was no slide to regulate.  After taking for Geek Squad at Best Buy, they couldn't do anything.  They have tried to put in the drivers and nothing has worked.  Then, I took the computer and called HP.  They also can't solve the problem.  This is a real joke, I can't control the brightness on the computer so now I'll go to Office Depot to get an anti glare screen, as we we.  It's absolutely amazing and no wonder people didn't go to Apple.  Any thoughts on how to remedy this situation?  Your opinion would be greatly appreciated.

  Hello

  Please report the number of HP for your PC product.  You will need to give drivers of Windows 8 and updates of the possible bios validated for your PC a try if Windows 8.1 drivers are not counted.

• Good for laptop - cannot change the ISP; keep returning to a previous provider

  Windows 7 laptop of my grandson, I'm migrating FIREFOX (excellent resource!) of my aging XP desktop. An existing Mozilla installation on the guarded device tries to connect to an ISP in Sydney (1000km) which kept out, I guess because the signal is too weak. Too far - on the Internet?

  Reinstalled my new ISP contact, reinstalled a fresh copy of Firefox, copied the old profile XP (just underneath the random string file name), but cannot change the fault. Firefox at startup tries to raise the old ISP (Sydney) and expires, and then allowing me to establish a manual connect with the ISP (my current) new.
  Perhaps a clue: in my Firefox troubleshooting info, change preferences, the browser start page is the address of 'old', with 'override mstone' ignore, what look like prints of registry entries, but I can't change all that - and maybe it's wise! An annoying secondary question: on arrival, the laptop listed no administrator user. So I am me came as an administrator, but I wonder if a past or current even Admin hidden could register (or other) entered resistant to change.

  Late discovery: the laptop is apparently infected with browser pirate btsearch.name. Search Google throws a series of removal procedures, and I'm now working through them.
  What Miss me?

  Sometimes a problem with Firefox can be a result of malware installed on your computer, you may not be aware of.

  You can try these free programs to search for malicious software that work with your existing anti-virus software:

  • Microsoft safety scanner
  • MalwareBytes' Anti-Malware
  • Anti-Rootkit utility - TDSSKiller
  • AdwCleaner (for more information, see this other AdwCleaner download page)
  • Hitman Pro
  • ESET Online Scanner

  Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP, if you do not already have one.
