I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

While dowgrading Lenovo g400s windows 8 to 7 the setup was stopped. When I press the restart button then it keeps restarting itself. I can enter into Bios but can't boot from any device (HDD, USB, DVD, CD) It gives message "Auto reboot (EC coldboot) count = xxxx. When tried to boot from usb, It loads only a few files then starts restarting

A:Lenovo g400s auto reboot (ec coldboot) count=2000

hi gapgrg,
 
Welcome to Lenovo Community Forums!
 
Have you tried Pressing the novo menue and try accessing the recovery.
   You might still be able to put back the original os back and start with the downgrade again.
 
You can also try booting from the DVD / CD or USB but you have to check if these settings in the BIOS are met.
 
 
Got to Exit Tab and Change OS Optimized Default to Other OS
 
  Save and exit the boot into BIOs again
  Under Boot Tab
          Change Boot mode to Legacy
           USB Boot should be enabled
    Under Security
          Secure Boot Has to Be disabled
          
Once All are Set Make sure to save all changed by hitting F10 and enter for Yes
    After Hitting enter It will Restart and You have to keep on tapping F12
       this should pull up the Boot Menu letting you select where to boot. You should have now your USB Stick as an Option or DVD/CD. Try to boot from those
 
Hope this helps
Let me know your findings
Cheers!

Ok, so, about a year ago I bought for my GF's birthday a G400s, and oh boy, if I knew it would be one of my worst purchases ever made, I swear to the seven heavens that I would just give the money to the charity... So the problems started with the Samsung HDD that came with the notebook, it stopped working in 3 months after the purchase, then after a long battle with Lenovo Brazil (witch by the way, is one of the worse company that I had the displeasure of ever getting to speak with their Customer support), I gave up and bought a new HDD and changed it by myself. Then again, the notebook made a favor of frying the HDD... Then after that I changed again, and guess what? The notebook won't boot up again!!!

Hi iyyappan_3,
 
Welcome to Lenovo Community Forums!
First make sure that the Audio driver and the dolby will be in sync.
Open Device Manager 
    Uninstall the Audio Device Under Sound and gaming controllers / Make sure to place a check in the Delete driver software prompt.
           
Now make sure you don't have any dolby components
    Proceed to Control Panel / Programs / Uninstall a Program
                     Uninstall all Dolby Related programs
                             Restart if Prompted
Now install this software driver
 
 https://download.lenovo.com/consumer/mobiles/audio142w81.exe
When you install this software it will show you a directory path whre it will extract, Make sure to Remember the path
 
This next xtep is important

Open the directory path where the Audio driver installer extracted the Audio driver.

Check all the folders inside it and find the Dolby Installers, Install the Dolby either Advanced audio or Digital plus.
 
ANd you should now get your dolby back
 
Hope this helps
Cheers!

Hi All,

Win8:
I have two wifi APs in the home and I have it all set up so that one is the Internet by cell phone tether and the other is the cabled network via the router wifi.

Works just fine - except.

On wifi 1, Internet I have it set for "Connect automatically" which at boot up it does.

On wifi 2, Network I also have it set for "Connect automatically" which at boot up it does NOT do. I have to go in and connect manually even though the "Connect automatically" is checked.

It seems win8 sees "Connect automatically"and does it but then stops checking other connections. Probably a "feature."

Is there some way to force both "Connect automatically" to happen?

Thanks

A:Wifi Auto-Connect to two-wifi APs, problem

There is a group policy setting for this, but even if both are connected you will only be using one of those connections at a time.

Hello, I was hoping that someone could shed some light on this subject. When I first bought this computer the only issues that I had were that the Windows 10 settings as well as the control panel settings were not indexed properly, and would not show up when I searched for them. After performing a recovery multiple times without any luck using the built in recovery option I decided to use the Windows 10 recovery media creation tool and reinstalled Windows 10 that way. This fixed the settings indexing problem, but now I have another problem. I can't seem to get the auto-rotate feature to work at all. I have installed the drivers for my particular model of laptop through the Lenovo Support page but my screen still won't rotate when I change orientations. Any information/suggestions would be a big help. Thanks!

A:Lenovo ThinkPad Yoga 14 auto-rotate problem

Hi, welcome to the forums.
 
I was not able yet to be sure which is the driver that manages the autorotation on Windows 10 for this TPY 14. But I think it can be good for you to install the latest driver available for it and some Lenovo tools that are utilities to manage the computer.
 
Here are my general tips.
 
1) Try first Windows Update and update all the drivers and Patches
2) Try Lenovo System Update to get any new/missing drivers.
3) Try to install Lenovo Settings and Lenovo Companion from the Windows App Store, Lenovo Companion also has a "update driver search"
4) Sometimes all that software does not recognize some updated / missing driver. Check Lenovo's Support Site and search for your specific model drivers (use the full model number of your Thinkpad).

Welcome to Lenovo Forums.
 
I would say, it's a driver problem. I have recognized a similar behaviour with an Atheros card/driver. I was able to solve it uninstalling the driver. Also you could try a system restore to when it worked fine.

The Lenovo Z70-80 80FG I received mid-March 2015 was having wifi connection problem. The wifi connection was only working when very close to the router. As suggeted on a blog, swapping the two antenna wires connected to the Qualcomm Atheros Wireless Network Adapter has resolved the problem. The cables are not soldered so it is easy to swap them.













Solved!

A:Lenovo B590 + Win 10 = WiFi problem

Hi Swarm23 , 
 
Welcome to the Community Forums. 
 
Just a headsup B590 may be affected by Win10 upgrade as a non supported model.
Windows 10 Upgrade Guide - IdeaPad and Lenovo NotebookLenovo supported systems list for Windows 10 Upgrade
After upgrading to Windows 10, some software or hardware functions of your computer might be unavailable. In addition, some software issues might occur. Installing the latest Windows updates, device drivers, and application updates may fix these issues 
 
Same reasons why support site do not have compatible driver available at the moment. 
 
What you can try is to go to the device manager and right click on the Wireless card under network adapter . Choose properties. Uncheck box on Power management tab "Allow to turn off to save power".
Go to Advance tab and set roaming aggressiveness / tendency to highest and restart . 
 
Check if there is a better connection , else proceed with choosing native driver offered by Windows .
Go to device manager and right click to update drivers , browse my computer , let me pick from the list and choose among those offered . Try each offered driver starting from top. 
 
Update us how it goes. 
 
 
Regards

Hey all,  Just recently bought a Lenovo Y520 gaming laptop. Overall very satisified with it! Last week I added an SSD drive to it and decided to do a fresh reformat from the BIOS so the laptop would run at full power without any bloatware holding it back.  Did the reformat sucessfully, installed all drivers, and now the laptop is running perfectly, except for one thing.  Since the reformat, Wifi has been giving me constant problems. I've tried just about every solution available on the net but so far have had no luck. It's main issue is: when I go to power on the laptop after being turned off for an extended period of time (at least 8-10 hours), there's no wifi at all whatsoever. Windows doesn't detect my wifi at all, even under network adapters! I've downloaded the latest drivers directly from Lenovo and even took it one step further by getting direct drivers from intel themselves. In this condition, it only detects my ethernet port, so when I go to diagnose it, it doesn't consider Wifi an issue because it doesn't think it exists.  The ONLY solution to get Wifi to work for me is to restart the computer at least once, load up the BIOS, go to the Configurations tab and disable/re-enable Wireless Lan. After that, I boot it with the saved changes and boom, Wifi suddenly works again. Thing is, I shouldn't have to do this every time to get Wifi to work. Before the reformat, the Wifi was working absolutely fine with no issues whatso... Read more

Hi  I bought a Lenovo G500 around a month ago (Windows 8.1, Intel Core i7 2.20 GHz, 8 GB RAM, 1 TB Disk, Broadcom 802.11n Network Adapter).  I have a problem related to wifi connectivity. When i'm at home, no problems with networking. But when i'm at the college, where network is public and realized with a proxy, my lenovo sees the network, but can't connect to internet because the network is "unidentified" and i have a "limited access". My other PC and my HTC One continue to work fine with the routers and access points placed in the college. I tried everything: reinstall wireless drivers, reset winsocks and ip, disable Windows and Comodo firewalls, disable the energy options of the network adapter... but nothing seems to change, and every time i have the same problem: nothing fixes the issue. If anyone has any suggestions I would be very grateful! Thanks

Try this,
 
StepA.
   Open Device Manager and check under Network Adapters,
Remember what brand you wireless is ex. Intel, Realtek, or Atheros
   right click on it and click Uninstall.
      Place a check on the Prompt that says Delete Driver Software for this device.
Now click the View option at the top of Device Manager and select Scan for driver changes.
    Open Network adapters again right click and click uninstall driver 
Now
    On the same prompt for deleting the driver check if there is a check box still.
 
If yes Repeat the step until you don't see the checkbox anymore. then proceed to Step B.
If no Proceed to Step B,
 
Step B.
    Restart the computer.
 
Download and Install the driver below for what wireless you have
 Intel WLAN Driver 
 WLAN Driver (Atheros, Broadcom, Realtek)

For two weeks now I m experiencing a wifi problem on my Z500. Everytime the wifi works fine for two or three days, and then at a random moment all my connections disappear, and the router to which I am connected is just 1 bar strong (Router is in my room). As I delete the driver from the Qualcomm adapter in Device Manager and a new driver on the Lenovo website download it works fine again for a couple of days. At least 15 connections are available. Again I can use the wifi for two or three days and then the problem occurs again. Unfortunately I can t fix it anymore by downloading just a new driver. I tried dozen drivers. The one from Lenovo does not work, the one from Qualcomm does not work. Everytime the wifi works for a day or two, and then something happens and all my connections disappear, and the router in my room is just 1 bar strong. I ve got this laptop three years now, and never had any problem with the wifi. Two weeks ago I did a lot of Windows Updates and then the problem started. System recovery does not work on my laptop either (In safe mode without virusscanner), so that can t fix the problem as well.. Technical Details: - Lenovo IdeaPad Z500 - Windows 8.1 (64 bit) - Wifi Adapter: Qualcomm Atheros AR9485WB-EG I hope you guys can help me..
