• Problem with key 'Shift' Lenovo Y530

  I bought a Lenovo Y530 recently with Windows Vista 64-bit.

  I'm having a problem with the 'Shift' key as they seem to be related to some sort of function hotkey or short cut:

  Left Shift-> on a notebook left SHIFT press types "] yt ' and active / turns off the Capslock. He also started a search or find on the desktop

  Right shift-> by pressing the right shift key prints «...» MV' on Notepad and done something funny

  It is therefore impossible for me to use this laptop. I tried following things so far:

  1. disable the shortcut keys in the Intel Graphics toolbar

  2. all controls 'ease of use '.

  It seems that Shift key everything except what it is supposed to do.

  Any help will be greatly appreciated.

  Thank you

  Gerard

  Hello

  I think that I found a solution to the problem. Although it sounds randomly - but it works for me.

  It just open wordpad and begin typing shift with other keys at the same time and randomly - very random and very fast. Hmm and well, it suddenly begins to work properly. It's pretty random and the problem is back, but he always solved with this... well "method" (if you can call it a 'method').

  I have not had the problem for a few months now. So, it does not. It is not a hardware problem safe - and nothing to do with the access keys.

  It will be useful.

• Problem with the 2 lenovo yoga headset jack

  So every time I plug my headphones on my laptop while I watch a video a notification appears telling me that I just plugged my headphones. It's useless information and I know how to turn it off, but the real problem is that when this message comes up my sound disappears for a few seconds. Even when I turn off the notification there is still an audio delay and I can't hear a thing for a few seconds. Is it possible to fix this? It is also the 13-inch model.

  Why not uninstall the driver from Realtek. If so, this solves the problem, it's a driver problem.

  From there, we can work toward the question of fixing (if you prefer to use generic drivers M$).

• Problems with my Lenovo Y510P.

  Hello Lenovo community!

  I bought my Y510P reconditioned 3 months ago and it had worked very well up until recently my laptop would just turned off and would not yet initialize for a certain period of time followed with my adapter it's a "pulsed" strange noise. I tried to remove my my laptop AC adapter and pressing the power on button, but it did not work. After 1 hour later I plug back my power adapter and the noise disappeared and it may start again, but with a strange event, my computer would be a smell of burning electronic and metal from the AC charger plug.

  I'm worried if it just my adapter is faulty or would it be a problem with my AC charger plug because it's the second time he has done that.

  your welcome, please make sure that the input voltage is the same amount that is stated on the laptop and secondly please keep me updated so that I know if your OEM charger worked

• Problem with Windows Update after the new installation of Windows 7 Pro the Lenovo ThinkPad X 200

  I'm trying to do a fresh install of Windows 7 Pro on a Lenovo ThinkPad X 200. The product key is easy to find on the sticker of the ThinkPad. However, the version of Windows is hidden (for example, I can't check that my ThinkPad had originally installed Windows 7 Pro). I was able to install by using a Pro Win 7 SP1 CD ROM I bought for another installation. I used the ThinkPad I was trying to make the new facility on the product key. I was able to activate the Windows 7 Pro using the phone call and my cell phone. I checked the activation! However, I have problems with Windows update. The product key may be a different version of Windows 7. If so, why did it install and activate OK? Y at - it a fix for this problem or I have to buy a new version of Windows 7 Pro? Please note that I have not yet installed all drivers Lenovo ThinkPad as I can't seem to install correctly. Thank you!

  Since the issue is updated to Windows, it is not a product number key.

• I started having problems with the wireless mouse and the carpet of my laptop - Lenovo ThinkPad T420 mouse.

  Original title: right click on the mouse itself activating

  I borrowed a USB to a person at work and I started having problems with the wireless mouse and the carpet of my laptop - Lenovo ThinkPad T420 mouse. The left click of two devices works normally, however, sometimes she does not respond to clicks and it takes a few seconds to work. The left button was constantly starts to turn on, as if he was stuck. After that I hit Alt + Tab and modify windows it stops for a few moments and starts at a later date. I havo not found a specific condition or a combination of keys that may trigger the fault.

  I read a few posts on discussion forums, but all say that it could be a hardware problem, which I think is not, because both devices have the same problem and I'm sure it all started with the insertion of the borrowed memory stick. I scanned the readers to help Symantec's EndPoint Protection and installed Microsoft Security Essentials and performed a full scan, but found nothing. I even restored the system, but the problem remains.

  Should I get a different antivirus? How can I find the cause so I can find a better targeted solution?

  Try to install the drivers from this link and check.
