HP DV7-4285DX WIFI IS BARELY WORKING

i just ordered a new fan for my DV7-4285DX and i installed it. Now my WIFI signal is barely one bar and everything worked fine two days ago prior to installing the fan. i dont know if the two are somehow related but it seems strange that the only thing that has changed was the installing of a new fan. Every other device has a full signal.
please help

Hi,
My suggestion: check the antenna cables which are connected to the wireless card, just reset them and this work may help.
Regards.

TS1398 my new ipad works perfectly. the iphone 5, however, cannot connect to the same wifi, can barely get a 3G signal, and the power level is at 53% after being barely used for 1\2 a day. Is this a hardware problem?? My old 3Gs was fine until it died.

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

Windows 8 HP Pavilion dv7-4285dx Upgrade results in black screen after intallation finalizes.

I have a 2011 HP Pavilion dv7-4285dx with Windows 7 64 bit Home premium installed. The notebook/laptop has a AMD Radeon HD 6300M series display adapter with driver version 9.2.2.0 dated 9/27/2012 and an ATI technologies Intel HD Graphics display adapter with driver version 8.7771.1.0. The notebook/laptop has not had a hardware upgrade and contiains the orignal factory OS. BIOS is current to latest available.
The issue I had while upgrading to Windows 8 is after the install finalizes (settings and preferences are entered) and the system boots to the tiles screen, the display works fine. Clicking to the desktop works only for a few moments before the screen goes dark. Pressing the power button and/or closing/opening the lid results in at times a black screen (no power to the screen) or black screen (power to the screen) or a black screen where only the mouse pointer is visible and moves around the screen. Restarting the computer results in a repeat of the issue at times while other times it will boot directly to what appears to be the windows desktop. You can interact with the file folder icon on the task bar as well as internet explorer, and you can get the charms bar and tile screen. Any attempt to open computer management or any control panel or task manager will open the window as an icon on the task bar. You can mouseover the icon to "preview" a small version of the window but you can not click on it to maximize.
I attempted the following workarounds:
1) Clean install of Windows 8: Installs but fails with same result as above
Refresh PC from windows 8 rescue media: Works slightly longer until AMD driver fails and then reverts to situation above.
2) Uninstalling all display adapters (via computer management) and then upgrading to Windows 8: Results in microsoft drivers getting installed, works much as refresh above until AMD driver fails and then reverts to above situation.
3) In Scenarios 1 and 2, I also tried to use windows update within Win8 to update the drivers there are updated MS drivers available ,(dated as late as 10/27/2012) but intalling those drivers also resulted in a failure of the adapter within a short period of time as did NOT updating the drivers.
4) Disabling display adapters and then restarting: Results in a BSOD (Blue Screen) IRQL_NOT_LESS_OR_EQUAL Stop: 0x0000000A error during boot as the OS runs into trouble with the driver before Windows 7 boots. This happens if one or both drivers are disabled.
5) Disabling display adapters before in-place upgrade to Windows 8 results in the Windows 8 equivalent of a BSOD and results in the system shutting down and then reverting to Windows 7.
Through research, I determined some ppl had luck connecting another monitor/HD TV through VGA/HDMI and then using the function-screen button to switch, with my system this resulted in the same issue displayed on the TV/Monitor. There are also updates to ATI and Catalyst center available including drivers and installing these do not remedy the issue. Intel was checked and there are no drivers available as HP uses a "custom" driver for intel. Attempting to install any of these Intel drivers will result in a fail with a compatiblity error.
Windows 8 has no safe mode ability from the windows 8 rescue media disk, you cannot F-8 as you could in the preview. Safe mode must be reached via charms, settings, startup and then selecting safe mode as a boot option, which is not available as the display adapter malfunctions. In those scenarios where I was able to get a windows desktop to boot up as in the first paragaph I can get to the restart settings via charms, but clicking to bring up the restart menu requires another window to open which is only visible as a "preview" on the windows task bar.
if you are going to attempt to try any of these,
1) Use a third party software to image your pre-win 8 upgrade system that you can boot into from USB or CD;
2) Before starting the process, disable the UAC prompt and remove any passwords from logon, as those things will require you to interact with the OS and you will not be able to do this when the adapters fail. The screen will shadow out as it usually does but the prompt will not be viewable.
3) Create an ISO image of the Win8 install media and write down the product key. If you are able to get a successful boot, before the drivers fail, create a Windows 8 rescue media disk.
I spoke with HP tech support this morning (10/29/2012) they are aware of the issues and they lie with the display adapters. They are working toward a solutuion but there are none available at this time and no date when they will be available. They recommend checking the support website and having the web page autoscan your PC as the drivers will show there when they are posted and they will be installable from Windows 7 so there will be no issue with upgrading to Windows 8. Bottom line, do not upgrade to Windows 8 at this time.
MS Tech support escalation tier reps also informed me there is no present workaround available.
Hope this helps and saves somebody some time!

My laptop sat at BestBuy from Friday night until today (10-31-12)! They couldn't figure out how to fix the problem so I finally told them to revert my latop back to Windows 7! I hope HP reads these and will hurry up and make the updates needed so that I can run Windows 8 on my Laptop! I just bought mine in July of last year there is nothing wrong with it and after dropping about $1200.00 for my dv7-4285dx along with the Best Buy Geek Squad package I do not feel like having to drop more money into another laptop!! PLEASE HURRY AND FIX THIS I DIDN"T DROP $69.99 plus tx to not be able to use Windows 8! Even before I did the upgrade I had the GEEk Squad check to make sure I could make the upgrade and was told this laptop well surpasses the required minium to run Windows 8!!!!!!

WiFi in Asia works on iPhone but not Macbook Pro

I am currently traveling around Asia and I have my Macbook Pro and iPhone with me. I have had no problems connecting to WiFi networks with my iPhone (currently typing this message with it on my hotel's WiFi). However, my Macbook Pro has had endless issues. Sometime it works, but often it doesn't. The most common issue is that it gets a self assigned IP address and can't connect to the internet. It can usually find and connect to the WiFi network, but from there things get dodgy. As I said, it sometimes works fine. I would say it works on 1 out of every 3 networks that I try.
So far I have tried the following:
Renewing DHCP Lease (without client ID and with made up client ID)
Disabling firewall.
Turning off wifi and them back on.
Restarting computer.
Deleting WiFi service and recreating.
Creating new "location".
Repairing permissions.
Using different login account.
Manually entering TCP/IP settings copied from iPhone.
"Forgetting network" and rejoining.
None of the above has helped, except that one time renewing DHCP lease with a made up client ID did the trick.
I have the summer 2012 MacBook Pro 13" with OS 10.7.5 installed.
Any help would be very appreciated. :)

It doesn't seem like anybody is going to respond to this thread, but I guess I will keep updating it just in case (and perhaps if I ever find a solution it will be helpful to others).
Since my last post I have been to about 12 hotels in both Thailand and Cambodia. This issue has continued with some variations:
* At 3 of the hotels the wifi on my MacBook Pro actually worked! It seemed to work ok, with minimal speed issues.
* At 6 of the hotels the wifi did not work on my MacBook Pro, but worked fine on my iPhone.
* At 3 of the hotels the wifi worked on my MacBook Pro but was PAINFULLY slow (to point where I couldn't upload photos, could barely check facebook, etc). In fact, it was so slow that I basically gave up using the internet with my MacBook Pro and used my iPhone instead (which had normal speeds).
I have continued to search the internet for solutions and nothing has helped yet. It seems like this is a common issue with newer MacBook Pros, especially with OS Lion.
I have also concluded that this isn't necessarily an Asia specific issue. It seems like an issue with my MacBook Pro and using various WiFi routers with various setups. Some work, but most do not. Unfortunately I do not have access to any of the routers that I am using, so changing router setup is not an option.

Pavilion dv7-4285dx: cannot BOOT/POST to external VGA and internal LCD is dead (cracked)

I have cracked the screen of my HP Pavilion dv7-4285dx so badly that I cannot read anything on it. I am trying to boot to an external monitor on VGA port, but never get a signal.
I have tried the monitor switching key, but that doesn't do anything. I have tried disconnecting the internal LCD from the motherboard - no different. I have tried a CMOS reset by removing the laptop battery, removing CMOS battery, disconnecting power supply and holding power button down for >1 minute, then restarting with just external LCD attached, but STILL no video on VGA port.
The video adapter is okay, as it boots to Windows and then I have video on the external monitor.
Although it's good that I can use the ext. monitor once Windows boots, I need to have video at boot time to make changes to BIOS.
Does anyone have another suggestion of how I can get the BIOS to detect and display to external VGA at boot time?

Can not restore windows to factory condition on dv7-4285DX

I have an HP Pavilion DV7-4285DX running windows 7 HP. I noticed about two weeks ago that my support assistant is not working, i have tried reinstalling it but nothing happens. I tried tonight to restore the computer to factory condidtions but it says that it cant restore to factory because the Hard drive has been changed to dynamic. Ehat does this mean? and how do i fix it. I have everything backed up so i am willing to do anything to be able to restore to factory settings
PLEASE HELP!
This question was solved.
View Solution.

When you add extra partitions to the hard drive it changes it to Dynamic. Did you burn a Recovery Disc set? If so boot from the first one to reformat the hard drive and reinstall.
If you don't have Recovery Discs, you can try to change the hdd back to Basic by deleting the extra partition and booting with a utilty cd. The free version of Partition Wizard used to offer the ability to change from Dynamic to Basic-not sure if it still does.
Scroll down on the page and get Partition Wizard Bootable CD ISO and> ImgBurn to burn the iso image to cd-a guide on using ImgBurn to write an ISO to a disc is Here. Once created, boot from it. Process to convert to Basic is HERE

HP Pavilion dv7-4285dx dark screen

Hi,
I have a HP Pavilion dv7-4285dx. It has been working great until I shut down, put it in travel bag, and tried to boot up once I was at my destination. It gives a black screen, but I can faintly see the screen when I shine a light on it. I can see the desktop when I attach an external monitor to it.
Could you tell me if my screen has gone bad and needs replacing or is it something else?
BTW, I am running windows 7, if that makes any difference and the only change that I made, program-wise, is having Carbonite upgrade my machine to their newest version of software. That was done about one week before I had this problem occur.
Thanks in advance for any help with this.

i've had a quick look through myself and can't see the backlight either, you may have to purchase an entire LCD unit assembly which is very expensive (605337-001)
this can be purchased from the link below
http://www.chilternitparts.com/productDetail?PartNumber=605337-001
unless somebody else know the part number for the backlight specifically then this is all i can advise

Hi,
Try reinstalling the Graphics Driver - Download the driver installer on the link below and save it to your Downloads folder.
ftp://ftp.hp.com/pub/softpaq/sp50501-51000/sp50640.exe
When the download has completed, temporarily disable your Security software, then open your Downloads folder, right click the Installer and select 'Run as Administrator' to begin the installation. Hopefully, this should complete successfully. When finished, restart the notebook and see if this has helped the issue. Remember to re-enable your security software after the restart.

Iphone 6 plus wifi connection not working

I don't know what the deal is but, I'm getting notifications of emails, and messages but when I go to the app I have nothing there. The problem has expanded and now apps aren't connecting to any wifi. I thought it might have been 3rd party apps, but now even the app store cannot connect. I've tried my home wifi, and my work wifi. Using my data plan, I have no problems connecting to anything. I'm thinking this is an IOS8 issue that needs a patch. If somebody has any other suggestions, I'm all ears!

I have always used the iPhone's LED flashing alert to notify me when I get a call or text message. While I was on iOS 8 Beta 2-4 it was working fine. I did a clean install of the complete iOS 8 release and ever since then, the flash alert doesn't work.
Sometimes it will work on incoming calls, but will not work on text messages. I've tried soft/hard rebooting, clean wipe and fresh installs, and pretty much anything in between. Now, today I got my 128GB Gold ATT iPhone 6 Plus, and it's the same thing. Updated to iOS 8.1, reset everything/deleted all contents and settings. Both fresh install, and iCloud backups and still no alerts on text messages, but now I get them on calls. I tried my girls ATT 128GB iPhone 6 and she has the same problem too. My old phone was a 64GB iPhone 5S and hers was a 32GB iPhone 5. Everything was good until the official release of iOS 8.
I've tried searching for related issues, and haven't found anything since 2011 with a quick Google search. Most links just tell you how to turn the flash alert on but no new issues. All of my devices are on iOS 8.1. I gave my father my 64GB 5S with a clean install and he still has the issue as well. So, that makes my iPhone 6 Plus, my girls iPhone 6 and my fathers iPhone 5S not flashing LED on messages and sometimes calls. There aren't any custom vibrations enabled on any if the devices. Has anyone else experienced this problem? Is it a known bug or am I just not doing something right here? i never had an issue before the iOS 8 release. Any help would be appreciated.
Are you a developer? IF so try asking in the developer forum.

Never mind, problem solved. When I retunred to the Network tab the message had changed to "connected, no IP address" so I got that from the WiFi tab and configured the Ethernet manually. Have a nice day @:-)#

Sounds like the device was dropped at some point and damaged as a result.
Take it to Apple for evaluation and a replacement.

For the second time (I've been to the Genius Bar once already) my WiFi isn't working on my iPhone 4S. This is really infuriating and costly!!! I see others have the same issues. Can't Apple do anything about this? It's obviously a hardware problem!

For the second time (I've been to the Genius Bar already once with this) my Wifi isn't working. They gave me a new iphone last time, but the new one has the same issue as the old one, I'm guessing. I've tried resetting the network but that doesn't work.
I see others have this issue too.
If this is a hardware problem why doesn't Apple fix it? Or do I just have to wait another year for another upgrade?
Currently it's not costing me anything - yet - because I've got the Apple Warranty but this is totally frustating!!! I bought the original phone (which has been replaced in July 2012. The new phone (without working Wifi) is a month old.
Will try Restore via ITunes before (I will invariably) have to return to the Genius Bar for another Iphone 4S unless someone has an ingenius solution here?..?

For what reason, other than making yourself look foolish, would you ask questions that we users could not possibly answer as we're NOT Apple?
Basics from the manual are restart, reset, restore from backup, restore as NEW. Nothing more "ingenius" to suggest than these steps that Apple has outlined in the manual. If these steps don't work, then go back to the Apple store.

My wifi is not working please help..

i reset my phone and connected my wifi and everything worked fine . i was close to the modem at that time , then i come back to my room i have no wifi . i tried restoring it again , same problem, i don't know what else to try . any suggestions .?? i also tried turning the modem off and on , & still nothing .

Hi @meghanath ,
Thank you for your query.
I grasp that after installing he Mediatek wireless driver, when you try to connect to your network you get the prompt to input your network password but does not accept it.
It is your router that is not accepting the password. Do you have firewall on the router?
Here is link to HP PCs - Troubleshooting your wireless network and Internet connection (Windows 7)
Here is a link to the recommended drives for your notebook as you did not state if you obtained the driver from the HP website.
