Does the X220 display have an inverter?

Hi,
Does the X220 display have an inverter?
My story:
I got an IPS panel to normal one I have and I installed it... and It worked. But I wasn't sure that there any improvement in image quality I tried to put back my old panel. But something went wrong. The panel didn’t light up, but I can see the there is a faint image displayed. I tried to put again the new panel but got the same thing: no light is coming out.
I'm suspecting the cable as it seems very fragile.
Thanks for helping.
Solved!

Just trying to keep things a bit organized around here!
I don't work for Lenovo. I'm a crazy volunteer!

    Does the iPhone 5 Have Flash?

    The Puffin browser, available in the app store for a few bucks runs flash via a workaround.  You can get a free trial version which will run flash for 14 days so you can see if it does what you need.  A side benefit of Puffin, is that it displays full web sites, not the mobile web sites.  This is very useful for some purposes such as banking options not available on mobile.  I got it for a trip I was taking, and still use it from time to time when a site doesn't display properly on Safari.

  • Does the Mac Mini have a camera?

    Thinking about getting a Mac Mini because it is very affordable, and I hate my PC, does the Mac Mini have a camera for facetime?

    I think cameras are in the displays.  The Mini is the "scrunched" version of the tower.

  • Does the retina display help your eyes when on the computer?

    Does the retina display help your eyes when on the computer for a long period of time? Does it make a difference if you have eye problems?

    First, I'd suggest posting your question on the MacBook Pro forum. This is the Mac Pro forum, where the computers start at 50 pounds and go up from there (at least so far).
    Second, I think it depends on what your eye problems are. I can say that there's a lot less reflection off the screen than the standard MacBook Pro glossy screen; it's similar to the anti-glare screens that you can find on other Mac laptops. The Retina display also has the ability to present a much crisper image with compatible software.

  • Does the Flashback malware have an effect on OS X systems without java installed?

    Does the Flashback malware have an effect on OS X systems without java installed? Just asking since i do not have java installed...

    It's not likely, but better safe than sorry. See
    Helpful Links Regarding Flashback Trojan
    Visit Thomas Reed's site for insight and help: Mac Malware Guide
    A Google search can reveal a variety of alternatives on how the remove the trojan should your computer get infected. This can get you started. However, be careful about what you do as new variants of the malware circumvent the efforts of earlier tools.
    Also see Apple's article About Flashback malware.
    Apple has released Java updates for Snow Leopard and Lion users:
    Java for OS X Lion 2012-003; available only for users of Lion with Java installed.
    Java for Mac OS X 10.6 Update 8; available only for users of Snow Leopard.
    Flashback malware removal tool; available only for users of Lion without Java installed.
    Install whichever shows up in Software Update. It removes the malware (if present), updates Java (if present) and tightens up Java settings for the future.  You may download from Apple's web site instead of using Software Update, but it's important to know which one to get, because the other two won't work for you.

  • Does the Macbook Pro have a program to run Windows? If not, what is the best program to do so?

    Does the Macbook Pro have a program to run Windows built in? If not, what is the best program to do so. Purchasing a new Mac.

    No. The Mac does not have anything to run Windows
    You must install either virtualizrion software or use BootCamp to create a partition for Windows. Once you have done that then you must install Windows.

  • Does the iPhone 4S have a shutter on the camera?

    A month or so back my iPhone camera had something half blocking the lens. I was just wondering, is this the camera shutter? Or does the iPhone even have a shutter?

    It has a virtual shutter... but there is nothing physical other than a case or possibly your finger to block the lens.

  • Does the iphone 4s have voice assisted gps navigation system when ion is downloaded to the phone?

      does the iphone 4s have a voice assisted gps system when io6 is downloaded onto the phone?

    The iPhone has NEVER had an International Warranty. The warranty terms state, quite clearly, that Apple "may" restrict warranty & support to the country of original purchase. The only exception, are iPhones purchased in the EU, where the iPhone warranty is EU wide.
    You purchase an iPhone in Singapore, & you will have to return it to Singapore for all warranty & support issues.
    For iPhones out of warranty, Apple has an out of warranty replacement program.
