Lenovo G510 Laptop Windows 7 64 bit - no wired or wireless access.

I recently bought a Lenovo G510 laptop and installed windows 7 64 bit onto it. After the install, I had to install all of the drivers, and everything was working fine.
Today I opened my laptop after having closed it ten minutes earlier, only to find that it wouldn't wake up from sleep mode. After trying everything I could think of, I did a hard restart and chose the 'start windows normally' option. However, when Windows started back up, it no longer recognized 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. No other keys look like they control internet. The device manager says all of the network devices are working normally. I tried reinstalling the drivers, 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.
I'm all out of ideas. Anyone have any suggestions?

Hi nej,
thanks for posting and welcome to the community. As you may already know when it comes to wireless issue there are many factors that can cause that different factors to look at. However in your case I would suggest you to click on "Start" and in the search field type "Services.msc". Click on services and once the services window opens, search for "WLAN AutoConfig". Doulble lick on it and check if the service is started or not? If it is not, ensure that it is started.
Hope this helps.
Regards

Unknown Device in Device Manager for Lenovo G780 laptop, Windows 7

Hails all. I am trying to figure out what the Unknown Device is under Other Devices in my Device Manager. I recently got rid of Windows 8 and put Windows 7 64-bit on my Lenovo G780 laptop. I installed almost everything from the Lenovo site --- all of the drivers and such, software, etc. I cannot figure out what this device may be. The only external device connected to the laptop is a Kensington usb mouse. Any ideas?
I did run the PCI test program and the Motherboard test program that Lenovo provides and it didn't find any errors. Windows Update hasn't found update/driver/software for the Unknown Device. The Lenovo Solutions software only tells me to open Device Manager.

Welcome to the forum!
Since Windows Update didn't pick up any missing drivers, I'm guessing you are missing a driver for a device that would be propriatary to Lenovo. During the installation of Windows 7, did you install the One Key Recovery software ? If not, the One Key Recovery button maybe triggering that exclamation mark in Device Manager since there is no driver to tell Windows what to do with that button.
If that wasn't the problem you can try running Unknown Device Indentifier to see if that utility can indentify the unknown device. The free program can be found at the link below........

Windows 8.1 installation problem on Lenovo G510

Hi. I bought a new Lenovo G510 laptop. I downloaded Windows 8.1 from Microsoft DreamSpark, and burned ISO image on a DVD disc. When I try to install it on my laptop, I receive an error (it might be wrong translated):
Load Driver
A media driver your computer needs is missing. This could be a DVD, USB, or Hard disk driver. If you have a CD, DVD, or USB flash drive with the driver on it, please insert it now.
Note: If the installation media for Windows in the DVD drive or on a USB drive, you can safely remove it for this step.
I already tried changing the following options in BIOS but no effect:
Configuration tab -> SATA Controller Mode from AHCI to Compatible
Boot tab -> Boot Mode from UEFI to Legacy Support
Boot tab -> Boot Priority from UEFI First to Legacy First
Also, I tried to insert CD with drivers which was in the box, but - of course - no appropiate drivers were found.
What happened? How am I supposed to install a Windows 8.1? What should I try? Thanks in advance for giving any clues and answers
Solved!
Go to Solution.

hi JachuPL,
Welcome to the Lenovo Forums.
From this microsoft article, the error that you're getting maybe caused by one of the following:
- The installation DVD is removed during the setup process.
- A low-quality DVD was used to create the installation DVD.
- The speed at which the installation DVD was burned was too fast.
- The DVD drive cannot read the media.
- The ISO file is corrupted.
Things that you can try:
1. Verify that the Windows 8.1 ISO is not corrupted by comparing the MD5 / SHA1 Hash of the download file to the one from DreamSpark. To get the hash, download and install the Microsoft File Checksum Integrity Verifier and foillow this guide.
2. Instead of using a DVD, follow this guide on how to create a bootable Windows 8.1 USB installer and use it to install Windows 8.1. (use the USB 2.0 port on the unit).
Let me know how it goes.
Regards

Lenovo G510 Graphics Cards Driver Problem

Hi!
I just bought the Lenovo G510 Laptop, with an Radeon 8750, and installed Windows 8 64 Bit.
After installing the drivers from the provided CD, I get the following Bugcheck error code in WhoCrashed
0xA0000001 (0x5, 0x0, 0x0, 0x0)
when rebooting ,or when I try to open the Catalyst Control Center.
Actually the AMD graphics card driver seems to be responsible, as this problem does not occur until I install this driver.
I tried to use the driver provide at the Lenovo support page too (for both Windows 8 and 7), with the same result. The ThinkVantage System Update does not install an AMD graphics driver at all.
Accordding to WhoCrashed atikmdag.sys causes this error.
I would highly appreciate any help!

Hi Aimor,
Welcome to Lenovo Community Forums!
I’m sorry to hear that the Wireless driver is not getting installed in your G510 Laptop, I suggest you to download a fresh copy of the driver from the below mentioned link and while installing the driver right click on the downloaded file and select “Run as administrator” option to get it installed without any error:
WLAN Driver (Atheros, Broadcom, Realtek) for Windows 7 (32-bit, 64-bit)
Do post us back if the issue still persists.
Best Regards

Were you able to install all the drivers and Software After the New installation of Win 8.1?
Get the drivers here

Start with the Chipset installation first then whatever comes next.
Make sure you select the proper version for your Windows type and version.

Lenovo G510 Inaccessible Boot Device and Internal Empty Port 5

Hi! I´ve got a lenovo G510 Laptop and I´ve been having several issues lately with it. First, it sometimes does not boot (a blue screen saying Inaccessible Boot Device appears on the screen). On the other hand, there are moments when the DVD recorder is not recognized either on windows or BIOS. (On Intel Rapid Storage there´s a SATA disk for the OS and instead of recognizing the DVD recorder it says Internal empty port 5); but this is not always, just sometimes. Is it possible for the two problems to be conected?Best,

To me that sounds like a harddrive is getting ready to, or has, totally failed. If this is a new laptop or the warranty is still good, I would contact customer support and see if you can get it fixed.

My lenovo g510 shows black screen every time I power it on but the power lights are on .

Every time I power on my laptop it shows black screen.but fan is running and power lights are on. After detaching and reattaching battery several times onece screen turns on and laptop then works smoothly.but after shutting it down again on next day same problem persists. I have already tried power drain out method.but on the next go same problems arises.what to do.

Hi Anish1,
Welcome to the Forums
As per the query we understood that you are facing issue with black screen in your Lenovo G510 laptop.
As you have mentioned that black screen when turned on, can you hear the windows login sound?
Remove the battery and connect only adapter and check for the issue also connect only battery and check for the issue.
Connect an external monitor and check if the display appears in the external monitor then its a issue with the LCD, if there is no display in the external monitor then it might be issue with the motherboard, hence suggest you to visit the nearest authorised service centre.
Click here for the service centre and select your region.

Lenovo G510 can't access most BIOS features

Brand new Lenovo G510 running Windows 7 Ultimate 64. I'm trying to get into the BIOS to view things like my memory timing, but I also need to get into the system monitor so I can view temperature readings and also access and adjust fan speeds.
I can boot into some kind of BIOS using either the little Lenovo button, or by mashing F2, but neither of these BIOS pages are nearly as robust as my desktop BIOS settings have been.
This is my first ever laptop, so maybe this is normal, but it's frustrating to be told to change fan speeds to go into a menu which I can't even view, let alone modify. Hopefully this is just user error and not something related to the system.
Solved!
Go to Solution.

hi MarklonW,
Thanks for Posting!
For an OEM Laptop system this is quite normal.
Unlike Desktop that has a lot of BIOS Settings, Laptops only has few specially for OEM laptops where most of the settings are preset and non viewable inside the BIOS.
This is a link for BIOS screen shots of Lenovo System and you might find same settings in every system
http://service.lenovo.partner-management.com/et.cfm?eid=1437
There are users who tried unlocking / modding the BIOS (You can look it up online) but there are a lot more to it. and may cause serious damage to the system if done wrong.
I strongly suggest to use the system as it is
There are TEMP monitor software like HWmonitor to check GPU and CPU Temperature.
But for the fan speed Im doubt that it can be detected via software as it was tried before and there were no fan detected on the laptos.

Lenovo G510

Hi,I Bought Recently a Lenovo G510 (About Weeks) When I Start Playing Games,The Left Side Of The laptop Become Hot And It Start Blowing Hot Air out Of It.(I Was Playing Call Of Duty 4) .is It A Hardware Failure Or What?Please Help Me

Hi Thewolverine95,
Welcome to Lenovo forums
As I understood that you are facing the issue with the system heating when playing game in your Lenovo G510 laptop.
As you have mentioned that the system heats when you are playing game, this is due to the graphics card issue, as the graphics in the game is higher than the system.
As some of the games require high end graphics, if the graphics in the system is lesser than the game the system heats up, try with other games.
Try to upgrade the graphic card and check for the issue. Also try to update the graphic driver and check for the issue.
Hope this helps! Do post us back for further queries.
Best regards,
Ashwin.S

NAC differentiate wired and wireless users

We have NAC installed and are using it control both wired and wireless ports. We also have the Guest Server that we are in the process of implementing. We would like for only users that are created via the Guest Server to use both wired and wireless access, which we are able to do @ this point. Our issue is that we have a Guest account that we would like to restrict to only wired users, this account is posted in conference rooms for internet access only. We don't want this account to be able to be used on the wireless network, is this possible?
Thanks,
Joe

Where are those conference room guests authenticating currently ? Through Nac ? Through webauth on a switch linked with NGS ?
