Upgrading to Windows 8 - Lenovo u460

I wish to upgrade to windows 8 on my Lenovo u460 but I'm worried about driver compatibility issues. Can I just carry over the same win7 drivers onto windows 8? I'm mostly concerned about my nvidia 305m/Intel HD switchable graphics driver. Can someone point me to where I can get the correct drivers for my laptop? I looked through some of the lenovo resources but I couldn't find what I needed.
Thanks.

hi de1337ed,
Welcome to the Lenovo Forums.
Windows 8 has a built-in driver database where it detects and installs the right driver for your system, In an event that it doesn't detect your devices correctly, in this case, the Intel HD+GeForce 305M, you need to install the Intel HD Graphics first then install the Nvidia drivers
Intel® HD Graphics Driver for Windows 7* and Windows 8* 64 (zip)
http://www.nvidia.com/object/notebook_drivers.html
If you can't get the Nvidia drivers to install, you need to mod the inf file and add the device ID (see link below):
Modding 101 - Missing Optimus Device IDs
Hope this helps

WiFi problem after upgrading to Windows 8.1 Lenovo R400 ThinkPad

I have this problem after updating to 8 to 8.1
Right after updating to 8 to 8.1, all of a sudden my wifi stops working. I used my philips external wifi usb stick and now I'm able to get the internet going.
However if I disconnect my philips usb I no longer get the internet because the built in wifi that came with the R400 ThinkPad no longer works. I went through the device manager and under properties it tells me, 'Device not working properly' however it is up to date.
Im Running Windows 8.1 64bit Laptop Lenovo R400 ThinkPad

Hi Matti,
Thank you for replying back!
I suggest you to reinstall the Windows 8.1, as all the windows driver will not update, if you have upgraded the Windows 8 to Windows 8.1.
Please download Windows 8.1 separately and reinstall the OS, I hope this may resolve the issue.
Note: I am not suggesting for clean installation, only reinstalling the same OS.
Do not update the drivers from ThinkVantage system update utility. I suggest you to uninstall the current drivers and download the drivers manually for Windows 8.1 and install it.
Below is the link to enter the downloads page and download updates accordingly, please click on "Select Product" then in "QUICK PATH" enter the MTM no. select the exact model.

Drivers issue for Lenovo u400 after upgrading to Windows 8

I recently upgraded to windows 8 an after that facing driver issue for ATI Radeon graphic card and wifi, and also cypress trackpad software is not working. All the supported drivers provided by Lenovo for windows 8 are fake and none of them are working. I even tried to search for drivers for graphic card from AMD website but unable to find any suitable drivers.
And to my surprise when i called lenovo technical support for help, the representative told that no such upgradation is possible for older system, but in Lenovo wesite it is clearly mentioned that upgradion is possible and they are provinding windows 8 drivers for this model which does not works at all :-(
Kindly some one suggest some workaround for this issue.
Solved!
Go to Solution.

I had the same problems with the Cypress driver after upgrading to Windows. Based on I did I downloaded the Windows 8 driver for the Ideapad U300s and it works GREAT. There were no compatibility issues, shows up in Device Manager etc. It also has and icon on the task bar that responds to the F6 key for disabling. Best yet this driver has a Palm Rejection tab. I set it for heavy and no wild pointer movements so I find I now keep the trackpad enabled. NOTE: the file name of the driver I downloaded and installed is: Ogt102w8. Hope this helps you and can't figure out why Lenovo has a driver listed for the U400 that does not work while this driver works great.

Upgrading to Windows 7 with Lenovo original recovery disks

Hi all,
Here is the question. I got my x301 recently with Vista Ultimate on it. From the looks of it Windows 7 will be released soon and it appears to be much smoother system, hence I would like to migrate. Here is the question - would you reckon it will be possible to obtain from Lenovo a set of recovery disk which would return your machine into original factory condition, same as on Vista, but with Windows 7, whenever the new OS is out. Even if official free upgrade will not be available, I'm happy to pay for the licence upgrade or for the new license. The key concern is to burn original recovery setup on my disk, as if it would've been shipped with Windows 7.
Anyone got here similar experiences ? For example moving from pre-installed XP on machine to Vista in such a way ? And what are the opinions ?
Thanks !
Regards !
X301, 128 SSD, 4GB, Vista 32-Bit Ultimate

the decision to do this will be on microsoft, not lenovo. if microsoft offers a vista > 7 upgrade path then lenovo will be allowed to sell recovery media to customers who can prove current ownership via MTM/SN and COA. if microsoft doesn't offer such a path then you'll have to purchase windows 7 via retail channels.

Help, cannot upgrade to Windows 10 on Lenovo Y50-70

Hello everyone, I'm using a Y50-70. From yesterday until now, I cannot upgrade it to Windows 10. I'm using Windows 8.1 Single Language shipped with it. I've tried many ways: - Use wuauclt.exe /updatenow to force Windows Update download Windows 10. After few minutes "Preparing for installation", it says "Update failed. Please try again" - Use Media Creation Tool to update. I tried to choose "Upgrade this PC", no luck. Always generic error "Windows 10 installation has failed" When I choose to create USB bootable disc, I run setup and after processing to 24%, it stopped with same error "Something happened". - Follow other suggestions, I've changed Region in Control Panel to "English (United States)". Same error again. - Even when I downloaded original ISO from Microsoft website and create a bootable USB, it always "Something happened". No more info. These things are driving me mad. Anyone has successfully upgrade your Y50-70 to Windows 10, please help or share your way to do. Thank you very much.

This is kind of disconcerting. I did the reserve and did ALL the latest 8.1 updates and then finally my Windows 10 said it was ready. I read an article that said to right click on the box window that appears when you reserve and then choose check your upgrade status and after that loads, you can also check your compatability report to make sure there are no compatibility issues. I have done all that. I have also backed up all important files to an external HDD in case of failure. I don't know if any of the above will help the OP, but it may list any possible compatibility issues. Maybe your original version of Windows 8.1 is not activated? you can go to Control Panel > System to see that your copy of windows is indeed activated as if not activated, it may cause a failure. That could be a good reason to use the OKR feature. Lastly, seeing that you are overseas, is your 8.1 version a US English version of Windows? If not, perhaps that is why all the tools are failing because maybe you have to download and install whatever previous type installation you had before with Windows 8.0/8.1? I would think performing the Compatibility check as described above may tell you if you are trying to update with a wrong version? Just a thought. Now then, speaking of OKR or other possible problems updating such as I read the latest BIOS update could also cause failures, but specifically speaking about OKR, there are numerous threads out there with all kinds of advice, etc but for me it is too much information and some information may be outdated. So I have a few questions maybe someone can help me BEFORE I leap into the Win 10 arena? 1. I know after upgrading to Win 10, I have supposedly 1 month to downgrade back to 8.1 using the Windows downgrade function. The biggest quuestion I have is, will upgrading to Windows 10 delete my OKR option? 2. I have the Y50-70 Touch UHD with 500 GB SSD. What is the best method of backing up the OKR media for just in case? I have seen several cloning programs mentioned and the Pendrive thread, but I am just wondering what is the best and safest way to ensure the OKR works.I have a 2 TB external HDD I am currently using to perform manual backups with so maybe I could clone the SSD and if so, best software option? 3. Or is the OKR really not necessary if I have the Windows Media Creator tool on the USB drive (I have one for Win 8.1 and one for Win 10)? Is using the Media Creator Tool method better or worse than using OKR? 4. Lastly, in case of catastrophic failure, are discs available from Lenovo? I have found nowhere in the support section that mentions being able to purchase recovery discs and no, my Novo button does not give an option to burn my own discs. All I can do is make a System image file backup and honestly, I don't even understand that. Does that system image file then restore my OKR if I choose to restore from that system image? I'm sorry for so many questions but as I stated there are so many threads on the partitioning issues and restoring OKR and the DIY Pendrive thread to me is very confusing and seems to contradict itself in several steps. I just want to be certain of having a functioning computer if the update fails or I end up with the BSOD. This is my first time using a computer with UEFI and OKR that does NOT allow the burning of recovery files. I have gone through all the WIN 10 FAQs but they do not address these issues. Anyways, thanks in advance if anyone has any answers to my disjointed and probably silly questions. As I get older it seems computers are getting more difficult to understand or maybe I'm just resistant to change lol Thanks again and good luck to the OP with his issues! And I hope I don't have the same problems but I will let you know if I do! EDITED TO ADD: Does anyone know if the nVidia Driver issue with Win 10 forced driver updates has been resolved? Or, if I update, does that mean I will have those issues that were discussed on the web between the forced drivers from microsoft instead of the PROPER drivers from nVidia? Or is it best to sit tight and wait for resolution? I do not use dual monitors so that problem won't affect me but I also heard some nVidia issues of bad flicker were also reported. I checked the Windows compatibility tool and no the GeForce GTX960M is NOT listed so for me that means it is currently unknown if compatible. This is another reason I would like to know if the OKR will still function, just in case I lose my screen during update. lol

Lenovo Yoga 2 Pro, Can't upgrade to Windows 10 - "Something happened" error

I've tried several times and I simply can't upgrade to Windows 10 on my Lenovo Yoga 2 Pro. The instalation process exists with the absurd "Something happened" error. I tried to set the Locale to en/us, and tried to install the ISO through a USB stick but no luck! Earlier I had setup my yoga 2 pro as a dual boot with both Windows 8.1 and Linux. Although I've never made any change to my OEM drives, since I went dual boot the one key recovery service also doesn't work. I still have all those OEM drives intact. When I go to the BIOS setup, I have two boot sectors, one is the original windows boot, and the other is the new linux boot; but I'm not sure it is related or not.

Hi SteveU,
Many things been tried (read the original post) - hybrid shutdown, intel drivers, uninstalling and installing again Lenovo Energy Managment driver (win 8.1 one), trying to use the Windows10 default driver for Energy management, shutting down with holding the shift (or alt button) can't remember now, many many things and clearly this is a Micorosft issue + Lenovo. Not enough testing down before hand, but everyone is happy at Lenovo as our money is at their bank... and have got expensive bit of kit that we shut-down holding down the button - because is just better than pressing shut-down...
This is the second time I'm let down by Lenovo - was thinking will give them another chance but as you can see moderators viewing or post but none of them has got a solution - isn't that right Amy@Lenovo or Majestic
Clearly Ms and Lenovo will blame each other now.
Fed up with this...
Windows 8.1 is the way to go, don't know why I was hoping that the latest MS updates will sort the issue out - wrong again
At least the Mail app works fine now

Upgraded to Windows 10 on Lenovo Ideapad p400 touch, screen went dim

Hello,I just installed the free Windows 10 upgrade on my Lenovo Ideapad p400 touch last night. I woke up this morning and booted up my computer, and everything was fine until I attempted to change the brightness. When I tried to do this, my screen went very dim, and now I can't adjust the brightness (and I can't read my screen well, either). Normally, I would install/reinstall the video driver in order to fix this problem (recommended for other users with similar issues), but I currently do not see a Windows 10 version of the driver I need on the Lenovo website.I was wondering:a) if/when a new driver would be available to install (if that's the recommended solution)b) is there something else going on?c) Windows 10 allows you to revert back to Windows 8.1 within the first month of use. Should I just do this?d) Is the p400 touch capable of running Windows 10? Why or why not?Thank you!

Hello. I also have a Lenovo Ideapad p400 touch. Screen also went dim on me. In Windows 8.1 just uninstalling graphic's driver worked. It was Control Panel, Device Manager and then Display Adapters. That doesn't work with Windows 10. The other solution of rebooting and press the increase brightness key at the Lenovo logo somewhat works but it doesn't turn the brightness all the way up. So I found this worked for me: Go here: http://support.lenovo.com/us/en/products/laptops-and-netbooks/ideapad-p-series-laptops/ideapad-p400-touch-notebook/downloads/DS031547 And just download and reinstall the old graphics driver for Windows 8. That finally got me back to maximum brightness.

Help! Optimus automatically switching after upgrading to windows 8

Hello,
I have a Lenovo u460 laptop that has NVidia 305m+hd 3000 switchable graphics.
I recently upgraded to windows 8 after taking the advice in this thread:
http://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/Upgrading-to-Windows-8-Lenovo-u460/td-p/112...
Now, whenever I try boot into windows, my screen keeps flickering after the boot screen. Its not a fast flicker, its the type of flicker that occurs whenever you would normally hit the optimus button. It's like the optimus button is being toggled continuously. As a result, I'm never able to reach windows!
I can change the graphics settings to discrete, and then I'm able to go into windows fine. But it forces me to use the NVidia card which is a battery drain. I would much rather only use the intel card than the NVidia one.
What do I do?

I have the same problem - my data had better not be gone! Why won't Apple address this problem?

Help Needed :- Upgrading to Windows 8.1 from Windows 8 on W540

I have tried repeatidly to upgrade to Windows 81 from windows 8 and it fails I get the driver power state failure error and error codes 0xc1900101 0x40017 .
After 4 failures , i deleted drivers for Prinfing (pdf / printer drivers etc ) and some others i didn't note tried to do the install and it worked, except the first time i rebooted after logging in , it would not boot into windows 8,1 driver it came up with the driver error messages again and i was given the option to reset to factory defaults and i did.
After restoring to factory defaults i tried the upgrade and it failed again.
So can you help me , in how do i upgrade to 8.1

"I bought a ThinkCentre M83 which had a downgraded windows licence (windows 8.1 pro downgraded to windows 7 professional)." -
"... Now you want to upgrade to Windows 8.1 that was originally offered when you purchased the computer. The only way that I am aware of that would be possible is to purchase a retail version of the newer operating system. "
I would say either you did not understand it well / or you gave the wrong info. If Lenovo Think(Pad/Centre) has Windows 7 Pro downgrade preload (but Win 8 / 8.1 Pro licence):
- user gets media for Windows 8/8.1 Pro included with your Think(Pad/Centre) (I think until December)
- or now you must order it here (free if entitled)

U410 touch WiFi issues after upgrading to windows 8.1

Hi all,
I have a U410 touch and yesterday I upgraded to windows 8.1
I have major WiFi issues.
connection drops after a few minutes giving limited. troblesshooting resets the adapter saying ''the default gateway is not accessible '' is fixed. But after a few minutes the problem comes back. and it goes like this forever.
I have the Intel Centrino N-2230 and I installed the driver I found here (15.10.3.2).
I''ve tried to uncheck the power management option but the problem is still there.
I also have other issues with the dolby system (I see others have the same problem )and my touch screen is not working.
any help will be greatly appreciated
thanks!

Hi-
I am also running into the same issue with my Lenovo U410 and it is really frustrating. I also have Centrino Wireless chip with driver version 15.10.3.2 and I have windows 8.1
I bought the laptop from Costco and was having similar issues. I sent it back to Costco Concierge who apparently replaced the wireless chipset on this laptop but now I am getting this issue.
Any help will be greatly appreciated.

Wifi problem of G560 after upgrading to windows 8.1

Hi,
I have a lenovo G560. After upgrading from windows 8 to windows 8.1, I cannot connect to wifi. I was wondering if someon else has the same problem.

hi amardoukhi,
Welcome to the Forums.
Your issue might be similar to this thread. Try the solution that was posted to rollback to an older driver version.
The solution was to:
1. Open Device Manager (press WInkey+R > type devmgmt.msc)
2. On the Device Manager, navigate to Network Adapters > right click on the wireless adapter and choose Update Driver Software
   - Link to picture
3. On the Driver Update Window, choose Browse my computer for driver software > Let me pick from a list of device drivers on my computer and choose the wireless card on the list.

T540p-Fan Behavior after upgrading to Windows 8.1 pro

Hi, i recently upgraded my T540p with an samsung evo 500gb ssd and installed windows 8 pro. I then upgraded to Windows 8.1 pro. My system runs smoothly and i am fairly happy with it. The only thing i have notised is that the fan kicks in every now and then. I have observed that the fan kicks in when the temp of the cpu reaches around 50 degrees celcious. This is a new laptop so the air vents are clean, and i am always using it on a desk. The fan produces a quite audible noise level and i guess it is spinning at higher revs when this happens. When the temp drops below 50 degrees i cant hear it at all. Has anyone else observed similar behaviour on their laptops?

Thank you too :-) I think we are not the only people who have this problem. Some other Germans have told about this problem too (http://thinkpad-forum.de/threads/172112-T540P-L%C3%BCfter).
Meanwihle, I have tested for this issue on Windows 7 x64. It’s the same behaviour. Same lower RPM after-sleep-bug (1600 RPM instead of 2000 RPM, Fan does not turn off any more).
I have taken the measurements from TPFanControl (http://www.staff.uni-marburg.de/~schmitzr/donate.html) and my ears ofc. Just used it with BIOS Fan Control (no custom fan control).
Please Lenovo, help!
Edit: Now tested at Ubuntu 14.10 Linux – same issue. Seems to be system independent. Must be a controller issue :-(

T430u hangs after upgrading to Windows 8.1

Hi, after upgrading to Windows 8.1 my Lenovo T430u started to freeze on some applications (specially ms Excel 2013). Sometimes the network connection was lost.
I did a clean install of Windows 8.0 and after downloading and reinstalling all drivers everything was working perfectly. Until I upgraded to Windows 8.1 again.
Now I'm having the exact same issues than I had when I first upgraded to Windows 8.1. I have installed all OS patches as suggested by Windows Update.
Is there any Windows 8.1 OS image that I can download from Lenovo that is tested for my machine? Or should I go back and reinstall Windows 8.0 and live with it?
Thanks
Adrián
