Lenovo T400 / T500 :: T531 Intel 82579LM Shows No Internet Access But Internet Works Fine
Jan 22, 2015
Taskbar icon for Gigabit Network Connection shows "No Internet Access". But Internet access works fine. But, since the driver thinks there is no access, I have to disable WiFi to force the laptop to use the wired LAN. Device Manager says everyhting works fine. Driver update says I have the latest driver (12.10.29.0 dated 2014-05-02). My T430 with the same adapter works fine. What do I do? Only difference between T530 and T430 is the T530 is in a dock.

I have recieved at work a lenovo t440 notebook, everything worked fine, untill one day I noticed that I cannot conect to the internet via lan cable. I plug in the cable and it is not detected. I checked the cable to another notebook and it was working. I have a Intel Ethernet Connection I218-LM controller, I have re-installed both network drivers from lenovo and intel websites and nothing works. I've tried as well to get automatically from windows update, no result. Went to bios cheked if the lan connection is enabled, everything was in place. Is there anything I missed? I noticed a weird behaviour, if I connect through wireless network, after sometime the lan connection is established and I can use it, but without wireless connection it doesn't work.

I had an extra Lenovo T410 sitting around so I wanted to restore it to its "factory state" by performing a "format boot". Plan was to boot from CD drive and reinstall Windows 7 (32 bit) during the process. However, disaster, after the process finished I am now stuck in some sort of safe mode (everything is larger than usual) and the computer is missing several drivers. I installed the network adapter driver manually (can identify networks but can't connect to internet). Device manager still lists Base System Device, Ethernet Controller, PCI Serial Port, PCI Simple Communications Controller, and Unknown Device drivers to be out of date.
My objectives here are to
1) restore connectivity to internet and
2) get Windows 7 Home Premium to full functionality.

I have a Compaq 3000 Laptop, it's almost 2.4 Years old now, over the period of time I dint faced any issues with my Machine.it all started yesterday.
I was watching a movie on my Laptop yesterday, after sometime the screen froze up but the movie was playing as I was able to hear whats going in the movie.
Later I tried restarting the machine, what i get is the machine boots up properly, but the screen doesnt display anything thing, it shows up a blank white screen, sometime when the windows XP loading picture comes up the screen shows light distorted colors but again goes white blank.
I did approached a local vendor for that but he says that we need to replace on the motherboard, I was not much convinced over his explanation over the issue.
I would like to know your views on what might be the problem with my Machine.
I am going to try over connecting an external monitor and see if LCD is the problem, but I would like to know more what all possible options are there which might be affecting my machine and how much would it cost me in the worst possible case.

I bought a new Lenovo Z50-70 laptop from [URL]
Following are the laptop configuration: Quick link:
Intel Core i7-4510U 2GHz Processor1TB Hybrid HDD8GB DDR3L 1600 Memory15.6" 1920x1080 LED Glossy WedgeIntel HD Graphics 5000Bluetooth 4.0Intel Dual Band Wireless-AC 3160DVD Recordable (Dual Layer)4-Cell Lithium-Ion BatteryWindows 8.1 (64-Bit)Initial setup went well. After 4 hours or so while surfing webpages, suddenly it started showing no internet connection and asked to reload webpages. So I looked at the wireless network icon on the bottom right corner which showed full bars. A few seconds later a yellow colored triangle with exclamation mark appeared on the network icon showing no internet and limited internet.
After turning the wifi off and back on the internet connects and works for few hours. After few hours, it lost internet connectivity again with the same above symptoms. I have this laptop now for 3 days and in past 3 days I had this problem at least 25 times.

Till now, my G510 with Win7 64 bit worked perfectly but after going into flight mode and coming back, it no longer recognizes any internet sources, wired or wireless.
Windows troubleshooter says I need to 'turn on wireless capability'. I don't see a wireless hardware switch anywhere on the laptop, fn+f5 does nothing and in the panel for the flightmode, only bluetooth appears (which I can also activate). The device manger says all of the network devices are working normally. I tried reinstalling the latest drivers from Lenovo, but that didn't do anything either. The Windows Mobility Center says that the wireless is turned off, but the 'turn wireless on' button is greyed out and is not able to be clicked.
In an earlier post, it was suggested to check if in "services.msc" the "WLAN AutoConfig" function is activated which is in my case true. WIFI is also activated in the BIOS.
Last thing I tried, was to bring with windows recovery the system back into a state where everything worked fine but also that did not work.

Lenovo Ideapad z585
AMD A10-4600M APU w/ Radeon HD Graphics @ 2.30 GHz
6 Gb DDR3 RAM
Windows 8 64-bit
Broadcom 802.11n Network Adapter
My network card is on the fritz, to put it simply. I randomly lose internet access, and my network connection is listed as "Limited Access". Sometimes turning off the adapter and turning it back on solves the problem, but sometimes I need to do a full reboot. My system is the only one affected, so I know its not the router. I have already viewed the similar threads and tried the methods advised with no success.
So far I have:
-Updated my drivers
-Disabled Broadcom Bluetooth service at startup
-Disabled Hybrid Sleep
-Told Windows not to shut the network card off.
I did a System Refresh last week and that's when the problem started.

I recently bought a t440s from a friend, And i wanted to lookup its warranty.The serial under the battery is recognised by the lenovo warranty check, But in the bios the serial shows up as R8000000, Could this become a problem for me in the future? refrain from bumping your thread(s) / post(s) more frequently than 3 days. Doing so, unfairly, pushes other members' threads downwards.

I have a T400 2765-P3U model, and it won't boot up. When you turn it on, you see the Thinkvantage logo and it stays there. Trying to access the BIOS is non-responsive. I connected the hard drive to see if it was a hard drive issue, but it's not. The hard drive is response when connected via USB. I can't get past the Thinkvantage logo, no response when attempting to access the BIOS. It's still under warranty, so I'll probably send it in for repair but thought I'd give it a try fixing it before hand.

I have Lenovo T420s plugged into ThinkPad Mini Dock Plus Series 3 with USB 3.0 90W. The problem I have USB 3.0 port on the dock (blue one) works as USB 2.0. The laptop port works fine. I am checking it by plugging Seagate mobile HDD - when the HDD is plugged into the blue port on the dock station Windows (7, 64-bit) complains 'Device can perform faster', using laptop's port doesn't trigger the message.
USB 3.0 driver is installed.
BIOS version is 1.37.
Intel Chipset drivers are updated.
Device manager shows the connection as a chain of two 'Generic USB Hub's, if HDD is connected to the laptop's port its chain of 'Renesas Electronics USB 3.0 .......

I bought my ThinkPad T530 laptop in August of this year and about a month ago I used the Lenovo ThinkVantage updater and it updated the driver for my web cam. Ever since then it has stopped working.
Whenever I open the web conferencing menu, it only shows options for the microphone, and nothing for the camera. I have tried hitting Fn+F6 and accessing it via other software e.g. Skype, Oovoo, Picasa. And they say that my webcam cannot be detected.
When I checked for the webcam in device manager it said it was installed and working properly, and that the driver was up to date. I went to the lenovo website and downloaded the driver for the camera from there (g1ca16ww) and tried to update the driver manually hoping that that would fix the problem. Alas, it did not. I also checked the BIOS settings to make sure that the camera was enabled. It was.
So then I tried to reinstall the driver by uninstalling it, and using the driver I downloaded from the Lenovo website to reinstall. It installed properly, but now the webcam is no longer listed in the hardware manager and the dropdown for Imaging Devices, where it was located before, is no longer visible. I also rechecked the BIOS menu to make sure the camera was still listed there and it is. I do not know why it isn't working. I have also tried system restore and that didn't work either, the device still isn't listed. I don't want to have to wipe my computer.

I have a new T440 running win 7 pro 64bit. The audio is not working.
When I first boot, the sound icon in the task bar shows that the system is muted, but the mute button (f1) is not lit.
-If I press the mute button the light goes on and the indicator on the task bar shows the system is no longer muted.
-If I have sound playing, when I toggle from the light on and the tray indicating not in mute to the ligt off and the tray indicating the system is in mute, I get a split second sound.
I have installed the realtek device drivers
I have installed the lenovo system update and all of the critical and reccomended updates.
The device manager indicates that everything is working properly.

In my business, we created supervisor password and enabled "lock BIOS settings" to prevent access BIOS on model T520i and T530i. But it's always possible to access on "read-only" to BIOS. How to prevent this access ?

I'm having major problems with my laptop. Will try and tell you as much as possible.
I have an HP Pavilion DV2700 (DV2799ea) that is about a year old. It has built-in bluetooth which can be quite tempremental. A week ago I searched the net for a way to get my bluetooth working properly and decided to download the latest version of bluetooth for my laptop from the HP website. I then restarted my laptop, like it said. The bluetooth worked perfectly. My internet connection, however, wouldn't work.
I tried going into the very beginning of the laptop and rolling the computer back to a few hours before I installed the new bluetooth in the hope that the bluetooth would be gone but my internet would be back (as I would rather obviously have internet than bluetooth). This did not work.
I also started the laptop in safe mode, but this made no difference.
I also tried diagnosing the problem, finding a new IP address, restarting the laptop again, changing router numbers etc.
I also tried disconnecting the bluetooth, but this didn't make any difference.
I also tried completely removing the wireless connection and then reconnecting it all, this also did not work...................

I contacted HP support yesterday because my HP Spectre 13 Pro notebook has a lot of difficulty getting wireless internet access. Sometimes it works well, sometimes it works then drops out; and it is never able to connect using my iPhone as a hotspot for more than 10 seconds.
HP support person instructed me to install 2 updates. Now my laptop is completely not working!! It says "Boot Device Not Found". I have to wait for a technician to completely replace the hard drive, then wait a week for a USB plugin to load up a new system.

I have a T440p with Windows 7 Pro. Except on rare occasions, I am unable to log into Windows with my first swipe across the fingerprint reader. The green light is on when I do the first swipe and it immediately goes off and stays off for around 15 seconds, during which time another swipe does nothing. Then the green light will return and a second finger swipe will log me on.
It's made using the fingerprint reader for login impractical, because it's faster to just go to the password screen and log in that way.

I can no longer use Simple Pass to log into a BOA on-line account. When I swipe my finger, a message indicates that simple pass is launching the address but nothing happens and the website doesn't open.Simple Pass came with my HP Pavilion DV6T-7000 CTO laptop with a 64 bit operating system. I currently use windows 7. Google Chrome is my default search engine but I also use IE on occasion. Previously when my Simple Pass worked, my BOA location was only opening in IE.

I upgraded my T410 with an Intel 520 240GB drive. It works fine but I cannot set the hard drive password. Whenever I go into BIOS and want to set the password, it would require me to enter it, then will work for some time (about 20 seconds) and say the operation was successful. However the option remains "DISABLED".
I found this thread which talks about the same problem with a W500. The only hint it gives is to put the hard drive in compatibility mode and retry it. I did that but it did not work. There is also a link to the Intel forum where this problem is discussed but the link is broken/the forum is down.

The problem is that when I try to update it keep telling me that my laptop does not meet the minimum requirement and it would abort the update.However, I dont get why it wouldn't meet minimum requirement and it doesn't note anywhere within readme file what is the minimum requirement to install this latest video driver.

After updating to the latest video drivers from the ThinkVantage Update Retriever, our Lync clients crash when sharing desktop on our T440P series and X240 series. I noticed when I uninstall the video driver I am able to screen share without incident. Also, if I update the driver from Windows Update I am able to share successfully. We use the update retriever and thininstaller to install our drivers in our environment. I have tried uninstalling the Lync updates all the way down to the base version and experience the same issue at every level. It crashes 100% of the time when sharing desktop. I have tested it on T440p machines in our environment that do not have the latest display driver, and no crashes occurred. Here are the specifics:
Thinkpad X240 [20AL]
Thinkpad T440p [20AN]
ThinkVantage Update Retriever 5.00.0007
Thinkvantage Thin Installer 1.2.0010
Intel HD Graphics Driver - gid634ww (10.18.10.3412)
Microsoft Lync 2013 SP1 32 Bit (15.0.4569.1503)

So, I just got my shiny new T540p with a 3K display and Win Pro 8 installed. I promptly upgraded to Win 8.1 Pro and now I have a problem with the Intel HD Graphics. Basically, the system will not turn the display on after a sleep and I can't adjust brightness.
I tried downloading the drivers from the support page, but they reference a Intel(R) HD Graphics 5000 card, whereas my system says it has a Intel(R) HD Graphics 4600 installed. When I try to run the driver install anyway, I get a message saying that my system does not meet the minimum requirement for installation (?).
I tried manually installing the Intel(R) HD Graphics Family driver instead. This fixed sleep and brightness control, but then all things 3D was completely messed up (like buttons in Skype and Chrome).
