Internal LAN adapter failure after upgrade to Windows 7 Premium

Upon boot up the following message appears for a few seconds, and then the boot to W7 continues successfully; except the adapter does not work.
“Initializing Intel Boot Agent GE v1.2.28.
PXE-E05: The LAN adapter’s configuration is corrupted or has not been initialized. The Boot Agent cannot continue.”
On 12/31/06 I purchased (Through the HP Store) a Pavilion dv9000t, p/n: EZ379AV, s/n: CNF7012K4X. aka: HP Pavilion dv9000t CTO Notebook PC.
I purchased an upgrade to Windows 7 Premium via the Microsoft store last February and did a successful clean install.
The LAN adapter error message appeared on my first W7 boot-up and has continued ever since.
What advice do you have? Using a USB LAN adapter is a pain.

Ethernet LAN not working after upgrading to windows 8.1

After upgrading from Windows 8 to 8.1, my Ethernet LAN is no longer working. Wireless LAN connectivity is OK. I have run the HP Support Assistant and downloaded the drivers for 8.1. Hovever, I do not see a 8.1 driver listed for the Ethernet LAN.

You're very welcome. See if the recovery manager still works so you can roll back to W8. Please read this guide for how to use it. http://support.hp.com/us-en/document/c03489643 If it doesn't then you will have to order a set of recovery disks from HP, or you can install this plain W8 OEM software this guy has posted on a link. Lots of folks have used it successfully, which is why I posted it. https://docs.google.com/file/d/0B0W9PBigPy94aVJWSndyTFNFMzg/edit?pli=1 Then use this tool to make the iso file bootable to a DVD or 4+ GB USB flash drive. http://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool Yes, that really stinks why you and I could not upgrade without an issue. I disabled about 5 or 6 devices in the device manager and the code 12 would not go away. I have no clue why the PC works fine on W8 but not on W8.1. My notebook is a few years older than yours and it worked fine on W8.1 but not on W10. Go figure...

What can I do if I get an internal power error after upgrading to Windows 10?

QuestionWhat can I do if I get an internal power error after upgrading to Windows 10?
AnswerSome laptops with AMD graphics that upgraded to Windows 10 are showing blue screens with error messages regarding Internal_Power_Error. If you receive this error, try the procedure in this article.
First, you'll need to quickly set the boot options to Safe Mode:
1. Hold the Windows key and press 'R' to open the run box.
2. Type MSCONFIG, then press ENTER.
3. Select the BOOT tab.
4. Under BOOT OPTIONS, check Safe boot, then select Minimal.
5. Click Apply, then OK.
6. Click Restart. (If prompted, click Restart anyway.)
From Safe Mode disable the AMD Display Driver:
1. Hold the Windows key and press the 'X' key to open a menu in the lower-left.
2. Click Device Manager.
3. Expand Display adapters to show the two display adapters.
4. Double click AMD Radeon R9 M200X Series.
5. Select the Driver tab.
6. Click Disable, then click Yes to confirm.
7. Click Close.
8. Hold the Windows key and press the 'R' key to open the run box.
9. Type MSCONFIG, then press ENTER.
10. Select the BOOT tab.
11. Uncheck Safe boot.
12. Click Apply, then OK.
13. Click Restart. (If prompted, click Restart anyway.)
From Windows 10 started with the AMD Display Driver disabled:
1. Hold the Windows key and press the 'X' key to open a menu in the lower-left.
2. Click Device Manager.
3. Expand Display adapters to show the two display adapters.
4. Double click AMD Radeon R9 M200X Series.
5. Select the Driver tab.
6. Click Update Driver.
7. Click Search automatically for updated driver software.
8. An AMD driver should be found and installed.
The driver that originally caused this problem is AMD display driver version 15.200.1046.2 dated 7/15/2015.
The driver installed through this process might have an older date, such as 15.200.1055.0 dated 7/6/2015. That's okay.

I'm having the same problem. I got error message 21. I went to apple store. they are saying i have a hardware error. Really, my phone was working before the update. Asked me for $150 to get another one when I am due to get a new one and wanted to pass this one on to my child.
Help please,
I will be glad to go back to the older software update

Internal Microphone inop, after upgrading to Windows 10

I have two HP Pavilion 11 x360 PCs, after upgrading to windows 10, both internal microhones do not work. I have tried using a bluthooth headset, (audio works) but the microphone does not. I have tried upgrading the soundcard driver using the Realtek High Definition Audio Driver ( Realtek Semiconductor Corp. - 6.0.1.7564) found on HP's driver website and is still will not work.

Rolled back one of the PCs to Win 8.1 and am in the process of updating the drivers, thus far the microphone still does not work.

No internet connection after upgrade from windows 8 to windows 8.1

I have upgraded my operating system from windows 8 to windows 8.1, I also updated windows 8.1 after the system upgrated. I found there is no access to internet, although I have full wifi signal. I tried to conncet to the router via ethnet cable, but it still has no internet connection. However, I can see other computers at homenet via wifi. I have seen some questions in the Forum regarding wifi failure after upgrating to windows 8.1, and I tried to uninstall all my drivers (LAN and wireless) of network adapter, and re-install the latest drivers from HP website at http://support.hp.com/gb-en/drivers/selfservice/HP-Pavilion-Sleekbook-15-b000/5296234/model/5311051#Z7_3054ICK0KGTE30AQO5O3KA30R1(I tried the Ralink ones as I remembered the old drivers are Ralink), but it does not work. Please could you help?

Hi @Koala76 , Thank you for visiting the HP Support Forums and Welcome! I have read your post on your HP Pavilion Sleekbook 15-b052ea and Windows 8.1 causing issues for you when trying to connect to the wireless. Try opening Device Manager, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager. In Device Manager, locate the network adapter, and then double-click the device name. Click the Driver tab, and then uninstall everything in the list except the Realtek and the Ralink. Remove any USB devices and Ethernet cables that are connected. Restart the computer. After you restart the computer, please use the HP Support Assistant. The HP Support Assistant has a wireless connectivity troubleshooting tool inside. Here is a screen shot of the Internet and Security tool that will help you diagnose Internet Connectivity. I hope this helps! Thanks.

Wifi problem of G560 after upgrading to windows 8.1

Hi,
I have a lenovo G560. After upgrading from windows 8 to windows 8.1, I cannot connect to wifi. I was wondering if someon else has the same problem.

hi amardoukhi,
Welcome to the Forums.
Your issue might be similar to this thread. Try the solution that was posted to rollback to an older driver version.
The solution was to:
1. Open Device Manager (press WInkey+R > type devmgmt.msc)
2. On the Device Manager, navigate to Network Adapters > right click on the wireless adapter and choose Update Driver Software
   - Link to picture
3. On the Driver Update Window, choose Browse my computer for driver software > Let me pick from a list of device drivers on my computer and choose the wireless card on the list.

Networking Issues after Upgrading to Windows 8.1

I have a Windows 8 desktop PC that is working fine with my network. I can browse the Internet fine using all major browsers etc. After upgrading to Windows 8.1 through the Windows Store I noticed that my wired networking was not working correctly.
The status of the network does not change (i.e. it doesn't change to Limited Connectivity) however browsing to sites in Chrome, IE or Firefox doesn't work as well as Windows 8.
IE11 gives me the error "This page can't be displayed, make sure the web address is correct" and other browsers give a similar error. I normally have to refresh 2-3 times to get a new page to load, sometimes even more. Everything works
fine from a laptop connected at the same time so it isn't an network issue with my provider.
I thought this might be a driver issue with the two on-board Marvell wired network adapters. I wasn't able to rollback the driver to older versions I found on the Internet. I then purchased another network card, Intel Desktop gigabit and the
issue still persists with that adapter. I then tried a USB wireless adapter and the issue still persists using wifi with the wired adapters disabled. I tried a new network cable and no luck either. I also tried resetting the IP stack using
the various netsh commands.
After that I thought I might try reset the Windows 8.1 PC, however that didn't work as I didn't have the restore image available as I upgraded from the Windows Store. I then tried installing Windows 8.1 fresh using a ISO with my Windows 8 key using
some of the recent guides that are available. That all worked but it didn't fix the networking issues.
I re-installed Windows 8.0 and the networking is now fixed and back to working normal again. I'd like to try again but I think I will have the same problems. I can't imagine why this would be a driver issue as I tried 3 different network adapters
and two installs of Windows 8.1. Any ideas what would be the cause of the Windows 8.1 issue?

HI,
Since this issue only occurred in the your desktop PC, and many network adapters you tried, failed, thus I think maybe we should focus on the model of your desktop PC, I suggest you update the BIOS and chipset from the manufacture to improve
the performance of win8.1.
Please also test this issue in safe mode with networking.
Please refer to:
Windows Startup Settings (including safe mode)
http://windows.microsoft.com/en-in/windows-8/windows-startup-settings-including-safe-mode
I’d like to share the following article with you:

Thanks for helping make community forums a great place.
The issue occurs in safe mode as well under Windows 8.1. The motherboard is an Asus P5B Premium, however it works on Windows 8. How would I update the chipset when booted into Windows 8.1? In Device Manager it wasn't allowing me to update
the network drivers as they were newer versions already installed.
Edit: I also installed at Intel Chipset Device software dated 8/8/2013 with version 9.4.0.1026 and the issue still occurs. I am also running the latest BIOS that is available.

WPA security Types are missing after upgrading to Windows 8.1

After upgrading from Windows 8 Pro 64bit to Windows 8.1 Pro 64bit on my Sony Vaio Duoe 13, I could not find WPA security type while configuring Wireless network manually. (only WPA2 and 802.1X are available).
I have done a lot of troubleshootings like
1-Reinstall Wirless original driver
2-Updating the wireless driver to the latest
3-Uninstall and reinstall windows 8 then upgrading again to windows 8.1
But the same.
Is there any way to add WPA to the security type?

Yes! It works!
To recap : My laptop has an Atheros AR9002WB-1NG adapter, windows 8.1. Even when it had windows 8, it was unable to connect, but unlike now, I didn't look closely enough about the type of network. Originally I thought it was
this problem. But they confirmed that others with windows 8 had no issues with this. Then , when I tried configuring the network manually, I could not find the WPA-enterprise option at all, only the
WPA2-enterprise.
So here I was, and Greg Seth's answer gave me an idea.
In the following instructions, some commands are obvious, so I won't explain unless necessary. So here's what you do :
0) Go to command line, preferably Administrator (not tried without).
1) C:\Windows\System32> cd \Users\<User>\Documents
2) C:\Users\<User>\Documents> netsh
3) netsh> wlan
4) netsh wlan> show profiles
5) delete profile name=<yournetwork>
Enclose the name of network within quotes, this is to ensure that you can cleanly set up the right profile. Don't close the netsh, we'll need it some more. If you do, just reach there the same way as before.
6) Right click the connection icon in lower right corner > open Network and Sharing Center > Set up a new connection or network > Manually connect to a wireless network
7) Try to create a profile, and try to get as many details to correspond with your requirement. The rest we'll edit in command line, so let's make it as easy as possible.
8) Do the same at the next screen. Edit Network settings > change all the parameters that you can, to match the requirement. My university tech support has a detailed document listing the options to choose, usually for windows 7, or even windows 8. get
as many of them as possible.
9) Finish. Move back to your netsh terminal
10) netsh wlan> show profile <profilename>
without quotes this time. This should show your previous attempt at creating a profile in the GUI dialog boxes. In my case, it had WPA2 and AES. It has to become WPA and TKIP. I also set my authMode to userOnly, since I hadn't done it right in the dialog box
before.
11) netsh wlan> set profileparameter
displays a humongous list of parameters with detailed options, just carefully examine the syntax. It's all here.
12) netsh wlan> set profileparameter name=<profilename> authentication=wpa encryption=tkip authMode=userOnly
13) netsh wlan> set profileparameter
Don't exit this yet.
14) Now click the connection icon, and connect to the network. It will ask you the username and password in a different style, that was my clue something was different this time.
15) It should connect. In my case atleast, it did. Verify by browsing.
16) netsh wlan> export profile name=<profile name>
In order that you're not put through this ordeal again, export the profile safely to a file. Again, the profile name in quotes.
17) Wonder why microsoft makes things difficult for us!

Hi,
You can also try to install the older version in compatible mode:
Windows 8.1 Wifi showing "limited" or "No Internet Access"
Solution: revert your network adapter driver back to an older version

Open Network and Sharing Center.
Click the Change adapter settings link in the upper left of the navigation pane.
Right click the network connection you want to enable/disable power management support on and click Properties .
Click Configure .
On the Power Management tab, clear the Allow the computer to turn off this device to save power check box.

T440s freezes when plugged in to AC after upgrade to Windows 10

After upgrading to Windows 10 my T440s shows the following behaviour: It boots up fine with the AC adapter plugged in. Now if I unplug power it goes into battery mode, i.e. darker backlight etc just fine. Now plugging the power back in, the screen gets brighter but the UI freezes. The screen freezes and the mouse pointer doesn't move. It doesn't seem to completely lock up though because when I unplug the power again everything comes back to life again. I have installed the latest Windows 10 drivers I could find to no avail. Anybody have the same experience? Thanks, Carsten

I am happy to report that this is fixed after upgrading the Intel HD Graphics driver from Windows Update via Device Manager. Not sure why that hadn't shown up as available directly in Windows Update.

Not able to switch on WiFi and Bluetooth after upgrading to Windows 10

I was using Windows 7 Home Basic preinstalled with the laptop since 2011. The laptop was working fine. After upgrading to Windows 10 the WiFi and Bluetooth is not working. Tried help from Microsoft remotely. According to them the drivers are not working and there is no updated drivers available for Windows 10 on HP website. The driver installed presently is "Broadcom 4313GN 802.11b/g/n 1x1 Wi-Fi Adapter".Please help and advise whether to stick with Windows 10 or to roll back to Windows 7 as I have an option to purchase a removable device to use WiFi and Bluetooth.I love the lightness of the new operating system. Please help!!!

If you have already reset your iPad the next would be to restore it agin. After that talk to Apple. Also see previous threads:

Hello rumbacha. I understand you're trying to locate some drivers for your SPECTRE for Windows 8.
There are quite a few versions of the SPECTRE so I will need your product number to identify exactly which model you have. This document can show you where the product number is located.
Once I have this I will attempt to locate the drivers for you.
Have an excellent day!

After upgrading to Windows 8.1 firefox longer works. I got it to load but screen is either blank or doesn't go to target address

after upgrading to Windows 8.1 from 8 nothing works correctly. Firefox 1st received 'unable to load XPcom' After resetting and uninstalling several times Firefox now loads to either a support screen or blank screen. It accepts address input but doesn't execute to target. So far I have been unable to roll back upgrade.
Although IE11 works, it doesn't work correctly.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
See:

If you keep having problems then do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 24: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you lose personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
