Dell :: M6400 Wireless Radio Shut Down
Nov 29, 2009
This morning when I turned the M6400 on, my wireless had shut down, showing a X on the tray icon.
It has been working fine under my Windows 7 Ultimate 64bit for weeks, since I used the free upgrade I got from the Microsoft Windows 7 demo. The Intel 5300 was fine in device manager.
When I ran the Intel ProSet Wireless diagnostics, it said that the Radio is Switched Off. The driver is the latest Intel 13.0.0 version for Windows 7 64bit.
I called Dell Business Support and the tech spent an hour uninstalling and reinstalling the driver, reinstalling the ProSet utilities and trying to find a way to get the radio to switch on.
He tried to uninstall the Intel generic driver and install the older Dell driver, but apparently could not get the Intel to uninstall, so the installation of the older driver kept failing.

I have a Lenovo IdeaPad Z50-70 and since almost 2 days i'm seeing that my wireless connections are not working/appear. Till about 2 days ago all worked fine. It says 'hardware radio off', i looked on google but nothing come up yet, i tried to "Reset PROSet" but still, after the reset it's the same problem. There isn't such a big problem, because i use an internet cable and all works fine, yet because it's a laptop i want to buy a router so there's the problem, i can buy it but won't work... as wireless.
How can i fix that? How to turn hardware radio ON? Is there a button or a key combo?

My laptop was working fine this morning. I took a nap and when I went to use the computer again, it can't find the wireless network. The network icon in the system tray is all gray bars with a red X through them. When I hover over it, the pop up says, "Wireless Network Connection Radio Disabled." Only two things could have changed: my daughter might have used the computer (using a non-administrator account) and Comcast cable might have gone out.
I'm using:
Studio 1458
Windows 7 Home Premium x64
Version 6.1.7601
Dell (Broadcom) Wireless 1520 Wireless-N WLAN Mini-Card
Netgear wireless router, Windows Firewall, Avast free anti-virus (have been using all three for years)
This is what I've tried:
-Verified that cable TV and phone are still working.
-Reset modem and then router then restarted laptop. (This is what I do any time the cable goes out and it usually works.)
-Verified that iPad and iPhone can see network and use it.
-Plugged laptop in through router and can see and use network.
Therefore it has to do with the wireless.
-In Network and Sharing Center, clicked set up a new connection or network and selected connect to the Internet > wireless. No connections available.
-Checked system restore to see if there's a restore point recently that would indicate my kid installed something. (Child of course denies using computer. ) Last restore point was Windows update five days ago.
-Restarted in safe mode, was unable to see wireless network.
-Verified that Device Manager sees wireless adaptor and says it is working.
-Deleted and reinstalled driver in safe mode.
-Deleted and reinstalled driver from latest downloaded version. This also deleted all existing network connections listed under manage wireless networks.
-Turned off wireless phones.
-Disabled LAN adaptor and retried all of the above.
-Tried FN F2 which pulls up an image of two radio towers. The one on the right, that looks like it's a tower without a signal, is highlighted and has a circle with a slash through it over top of it.
-Ran through troubleshooter numerous times.
-Restarted computer numerous times during this testing.
-Went into Windows Mobility Center to turn wireless on but button is grayed out.
In Windows Mobility Center clicked on "launch" under radio control options and selected All the Radios (WiFi was the only one not grayed out).
In Windows Mobility Center, found that the above was still an option so it appears WMC doesn't see that they're turned on.
-Updated the firmware on wireless router.
-Update driver for Microsoft Virtual WiFi Miniport Adaptor
-Manually added wireless network through Network and Sharing Center.
-Verified my antivirus software is working and is up to date.
-Changed security options on router so there was no security. (Of course changed it back.)
How to update the firmware on the wireless adaptor card if there is any.
I still have a gray wireless network connection icon in the system tray with a red X through it. The pop up still says wireless network connection radio disabled. I am unable to connect to the Interenet through the wireless, even in safe mode. This is my work computer (I own my own business) and in order to use the wired connection I have to sit on the floor in a corner. It's very inconvenient, not to mention uncomfortable. (My child does not usually have access to my computer but our home computer is down and I let her use it a few days ago and forgot to turn off the guest account.

My wireless card stopped working and I get the message that the radio is disabled. F2 is supposed to turn it on,but no longer does so. Tried reinstalling the wireless card driver, but that didn't work. I am told that I probably have a software conflict. How to find and correct the conflict?

Is there a way to turn on or off the wireless/bluetooth radio when the T420 is docked and using an external keyboard? I don't want to open the lid on the T420 every time to use the Fn+F5 keys when docked.

I have a Lenovo t420s with dualboot win7 and Ubuntu. I never had any problems until now and could switch on/off my wireless and bluetooth connections via the Hardware Switch (right bottom left of the notebook) or via FN + F5.
However, without any specific reason the wireless and bluetooth was switched off and the the system tells me that I have to switch on WIFI via the Wireless Radio Switch. However, although I can move it, it doesn't make any difference for the Switch.
I tried to reset the BIOS to Default and changed the network settings, and also rebooted several times. I won't work with any of the two systems.

It appears that Dell just removed the option for Intel wireless cards on the M6400... The Dell branded cards are now the only option...

I think being a highend gaming laptop SXPS 16 should have FM radio tunner built into it like Toshiba Qushimo.

Yup me again, in my hunt to determine if M6400 is right for me as it costs just about as much as a used car, I want to make sure its a good investment before I buy it.
What is the main difference with the M6400 and the M6400 Covet?
I configured both with the same specs and the Covet is about $900 more in price?
Does orange paint really cost that much?

The wireless switch doesn't work; indication light won't turn on. Tried Smartwifi, kept prompting me to turn on the hardware switch. This also measn I can't use the bluetooth. Spoke with sony support for hours and all they could tell me is to send it for repair. I'm out of warranty. Device manager doesnt report any problem with the driver. I updated the bios. I restored settings to factory default. Nothing worked.
I decided to open it up to see if i can replace the wifi board myself. But when i did get into the motherboard, it seems the wifi is internal and the hardware radio switch is broken. I checked out other motherboard photos with the same model and i noticed that there should be a tiny piece of plastic sticking out near the wifi part, next to the sd card slot.
Has anyone ever successfully or "magically" able to physically turn on a broken wireless hardware switch? Is there any software switch to bypass the hardware?

DV2400
Conexant audio w/ HD smartaudio HD2 driver
Cleared all cache, history, temp files...
ran several anti-virus, spyware programs to make sure this isn't a virus
Ok, this is how I noticed the problem. I plugged in my iphone earbuds w/ mic into the microphone jack in the front and used windows sound recorder to record voice. It didn't pick up much of my voice but it picked up a radio station. If i unplugged the earbuds and hit record again, it only pick up static noise. Has any of you experience this problem? Pretty sure this isn't a virus...just something our laptop does.

I have updated some months ago, my laptop 7859-5SG from Windows 7 to Windows 8 -> 8.1 and after that the bluetooth radio doesn't work anymore.
I tried to find a driver on the driver download section for my laptop, but I didn't find nothing. First problem found, is the hotkey fn+F5 that not show nothing on the display after key press, and normally with this function I can see if the radio is on or off.
I checked on the BIOS section if bluetooth is enable, and this is on. What I can do to activate bluetooth radio again?

I have just installed Windows 8 onto my T510i but I am unable to control the Bluetooth Radio. It seems to be constantly on.
If I press FN+F5 nothing happens (not even flight mode)
I have downloaded and installed all the drivers and software that I can from the Lenovo support website. Is there any thing I can do so that I can turn the Bluetooth radio on and off....

Several times a week, my bluetooth mouse will freeze. I can still use the touchpad or the red dot. Fix is to Fn+F5 and stop and start the bluetooth radio. Looking in Lenovo System Update, I can see the Bluetooth driver is a recent install and is version 6.5.1.4500 for Windows 7 [32/64].
Mouse is Targus bluetooth mouse, model: AMB09US

My Dell XPS 1645 [see sig for specs] will random shut off on me. I will be doing anything from watching a movie, listening to music, or just browsing and it will random shut off. They are like days apart but It shut off 3 times on my today :S.
These shut offs are not Temperature related as In BOTH Windows and Ubuntu it has shut off and I have been monitoring temperature in both, with log files so I can check the temperature @ shut off time.
I live in Jamaica and it would be kind of hard for me to just send it in to have it looked at. I'm hoping the next BIOS revision along with fresh installs of both OS's will do the trick.

I've had the E6400 for about a week. It's been perfect until today. Three times now, the computer has just shut down as I was using it, not falling asleep, obviously. It won't start right back up; I have to wait about 30 seconds and then it boots back up to normal. The fan is working and I set the power settings myself.

I have a Dell Studio XPS 1340 (mid 2010)
Windows 7 Home Premium
When I turn off the computer, it does not turn off all the time (sometimes it does, and most of the time it doesn't), the screen truns off like it wants to shut down, but then the computer hangs up, with the HDD disk light flashing, and it never shuts down, requiring a hard shut down.
I have not installed any new software...nothing different has happened, and I did try system restore, going back quite a ways, it did not work....

I have replaced my old CPU (T8300 2.4/3M/800) with a new CPU (NEW SLGEE Dell Intel Core 2 Duo T9900 3.06GHZ/6MB/1066 Mhz Socket P CPU Processor )...All I get now is when I start the computer the "power LED" will blink once and beep once and then the "battery led" will blink once and then it will shut off. If I remove the new CPU and replace it with my old CPU it works fine...Does this sound like the new CPU is bad or not supported by my motherboard? From what my manual tells me this CPU should be supported by my motherboard. My manual says it can handle Intel Core 2 Duo, 6MB and 1066 FSB. Dell verified that my system is socket P.

I'm using either a usb or bluetooth mouse with my new XPS 15z, and i'm getting tired of a problem...
The trackpad is impossible to shut down for good... i mean: indeed you can disable it, turn it off, and even tell it to turn off when usb mouse is plugged, but it never really does, it always, always, always stays on for a second before shutting down...
In other words: my trackpad is disabled, both buttons and touch, and i use a bluetooth mouse. but even it is disabled, if i pass my fingers on it, the cursor moves for 1cm before shutting down... then i wait 2 minutes, and i pass my fingers on it again, and then again the cursor moves 1 cm before stopping moving.
So it is never really shut down, with the consequence i never can type text without my hand touching it and putting the cursor somewhere in the page and i have to put the cursor back to where it was,
For example it happened 5 times when typing this very text....
I have updated the cypress trackpad drivers to last up to date version...

I'm running a dual boot on my m1530 with Vista and XP. I used a link I found on these forums to find the XP drivers, put them on the disc, and install them that way. I tried to find the link again, but I cant.
Anyways, the problem is that when I close the laptop lid in XP (the problem does not occur in Vista) the screen goes black (maybe into hibernation?) and I have to hold the power button down to shut down the computer and restart it. I've tried fooling around with settings and that doesnt help.
Maybe it's a driver issue? Can some one lead me to the correct driver...or tell me what else may resolve the problem?

It started about a week ago. All the sudden I went to pick up my laptop while it was open and the screen just shut off.
The computer was running, but the screen wouldn't come back on. I tried closing it and opening it and it didn't do anything....so I turned it off and back on and it would flicker light in the bottom right hand corner but no image would appear.
Then eventually, after I kept trying it just started working again like normal until yesterday when I was watching a video and all the sudden it just shut the screen off..

I just got my new Dell Inspiron 5523 laptop last week and have noticed that it will frequently just shut down on me. It isn't plugged in, doesn't feel hot and I don't even have anything up but IE. What is going on? A brand new laptop shouldn't be acting this way...
