X100e monitor not recognized by computer anymore

Hello folks,
I am using X100e and recently after I applied some Windows Update, the computer's monitor stops displaying at all. I can still use an external monitor, but the computer seems to fail its own built-in monitor. Situations are the same even after I reinstall everything including Windows 7 OS. Since it works fine with an external monitor, does it mean that the built-in monitor is now physically dead?
Thanks in advance for your comments!

There are few chances
The panel itself is failed
The flat cable is broken
The flat cable is misplaced in one of its ends.
Your first option is to contact the lenovo support, especially if the notebook is still covered by the warranty.
If not, you may think to check for the flat cable and its connectors, or even to replace the lcd panel yourself.
Depending on your skill

Monitor not recognized by Mac anymore?????

Hi
This is big and what is APPLE doing to solve this issue??
I just copy some posts from the forum to show how big this issue is, there is 8 more pages with the same problem, and i am one of them!!!!
HELP!!!! WE ARE FREAKING OUT HERE AND NEED A SOLUTION!!!
Yes, me. I have an HP w2207 who worked with my 3 y.o. old MacBook (OS 10.4.??) via the DVI-port flawlessly. Then bought a brandnew MacBook Pro with 10.6.X and the external monitor stopped being recognized. It works now that I have changed the connection to the VGA-port of the monitor (and bought yet another adapter for the MacBook Pro) but the quality is not what I'm used to.

Yes. I've tried 7 different Macs including a MacBook Pro with Snow Leopard (10.6.2) and my external monitor doesn't work with it either.
For me here's a recap:
Installed SL on a Mac Pro connected to a 23" Cinema via DVI and Olevia 537 via HDMI Input #1 and now that input no longer works with Mac computers.
Reinstalled 10.5.8 on the Mac Pro and HDMI #1 still didn't work, so I plugged the Mac into HDMI #2 and it worked.
Reinstalled SL on the Mac Pro connected to a 23" Cinema via DVI and Olevia 537 via HDMI Input #2 and now that input no longer works with Mac computers.
Since then, every device (PCs, DVD Players, Video Cameras, etc...) I connect to either of the HDMI inputs work fine. However, neither HDMI input works with ANY of the 7 different Macs (regardless of OS version) I've tried, except for a 10-year-old G4 running Panther or Tiger.
The monitor had previously worked with the MacPro (HDMI input #1) and a G5 (HDMI input #2) for almost 2 years.
When I plug the MacPro into any other monitor via HDMI, it works fine. Same thing with the G5.
My theory is still that the installer for Snow Leopard somehow made my monitor's HDMI inputs incompatible with Macs. I'm so frustrated that I'm ready to buy a new monitor, but since there's no guarantee that a new monitor won't be adversely affected by Snow Leopard, I'm still dubious.

Another "me too" post...
Not sure exactly when it stopped working (since I don't use it every day) but my Viewsonic VX2455wm stopped working with my MacBook recently too. Checked with another MacBook (six months newer than my Late 2006 model) and that exhibited the same problem. Both machines have fully patched Snow Leopard installs. Both started with Tiger. Mine is regularly connected to the external monitor, the other has never been connected. I'm connecting using a DVI cable and a mini-DVI-DVI adapter.
The monitor appears to work correctly. I've checked with a Windows laptop connected on the VGA port. I want to test with another DVI-enabled machine to see whether or not its the cable.

Hi Guys
I have the same problem with my new Dell 2209WAf. It worked fine before i changed from L to SL.
I didn't know what happened so i have spend hours and hours to resolve the problem.
Hours with Mac support and friends didn't change anything, i still cant make my Dell to work, or show up in preferences. I am working as a photographer and this issue is a real problem.
I just heard from Mac Support that Apple is working on it.....well, doesn't help us with the problem today.
So Apple, DO SOMETHING ABOUT THIS! NOW! this problem should NEVER showed up, this is something you should have fixed before telling all the Macers to upgrade!!!

Experiencing the same issues. However, on bit different hardware.
I'm using the XLR8 ProView USB input devices. Using these devices on a mixture of 10.5.8 and 10.6.2 systems (2 MacBooks, 2 Mac Mini and 1 iMac).
I can confirm the following:
When attempting to mirror video, or extend the desktop, using a mini-DVI to S-Video/Composite device on OSX 10.6.2 no video is sent to the mini-DVI device (inputing into the XLR8).
When attempting to mirror video, or extend the desktop, using a mini-DVI to S-Video/Composite device on OSX 10.5.8 video is sent to the mini-DVI device (inputing into the XLR8).
Let me also state, that the mini-DVI port on the Mac Mini's do work. They have been connected to 19" monitors and working without issue. Today, the mini-DVI devices were replaced with minidisplay port devices, which are use in conjunction with the mini-DVI ports.
It would appear, in my case, that the problem is that the mini-DVI port on both the MacBook and Mac Mini, running 10.6.2, as a secondary display device is not operating properly.

Same problems here. I reloaded OS 10.4.6 which is what shipped with my MBP1,2 17" 2.16 Intel Core Duo 2GB ram and after installing that, i was able to select 1920x1080 for my external HP w2338h, DVI-VGA, never been able to connect DVI-HDMI. On SL, the max rez I was able to "use" was 1600x1200 which looked horrible. So this leads me to suspect that this must be an issue with SL.
I spoke with Apple Tech support on Sat and was no help. The only suggestion was that I take my MBP and Monitor to the Apple Store. Those of you who are fortunate enough to live in Chicago in the winter, then you know that option really isn't that feasible, it is but just a giant pain.

I have an iMac 9,1 Intel Core 2 Duo that I bought last June. It came with Leopard, but I upgraded to Snow Leopard. Currently, it's running 10.6.2. My HP w2207 Widescreen monitor works perfectly with it using the DVI port on the HP and the mini-display (not mini-DVI) port on the iMac.
However, I just bought the top-of-the-line iMac 11,1 Intel Core i5 QuadCore three days ago and it crashes nearly every time that it wakes from "sleep" when the HP w2207 is connected to it. It doesn't even recognize that the w2207 is connected to it. Additionally, when the w2207 is connected, it (a) looks terrible - very dim and very granular, and (b) causes the iMac QuadCore to operate very sluggishly. When I disconnect the HP w2207, the iMac QuadCore is lightning-fast.
Much like my older iMac, the QuadCore is running 10.6.2 and I'm using the mini-display port.

This is a Me too post, I have a MacBook and NEC Multisync Monitor that worked fine before I upgraded to 10.6.2. I've tried to get it to work without any luck. I've written NEC to see if they have a solution.

Another me too post. I have a new 17" MacBook Pro with 10.6.2 installed. Trying to connect to an HPL2245wg - sometimes it works flawlessly - other times not at all. Some mornings I spend 30 -40 minutes rebooting, unplugging and plugging the monitor, Detecting Displays, changing the Graphics Card (Energy settings) - all to no avail. Very, very frustrating Apple - please figure out what is going on with this issue....and get it fixed!

Wow, me too. Did a minor software update (apple released it) last night, got on this morning and BANG - my main 24" Dell display is NOT working.
This is ******, apple have surely f**ked up here. It's never had a hitch, ever, since i bought it 9 months ago.
We are all reporting the same thing - software update, and then no working external display...

I seem to have found a fix for myself. I was having terrible issues with the screen blinking and flickering constantly. I tried to reset the SMC with everything unplugged and the computer would not reboot at that point on it's own which led me eventually to reinstalling SL.
Reinstalling SL is quite painless actually as it installs on top of your profile. After reinstalling I ran software update which installs the cumulative upgrades. Now I usually don't have any problems but must follow the instructions to run in clamshell mode to the letter.
After a week of running in clamshell mode I started having an issue with the dock not lining up so I put the computer to sleep, disconnected the monitor and restarted with nothing connected. After that, followed the clamshell mode instructions again and have been working fine again all week.
I've also disabled my screen-saver, and deleted the windowserver preferences as part of my debug process but not sure if that has contributed to my new found stability.

Me too. I have a MacBook Pro 2,2 running the latest Snow Leopard 10.6.2. After I have installed yesterday's security patch it does not recognize external displays on the DVI port any longer. Tried it with a 23" DELL at the office and a 23" Samsung at home. Both have worked without any problems for years.
I am curious to learn how this behavior is related to security...

IPOD Shuffle not recognized by computer, and caused a USB power surge

Device is not recognized by computer, and I tried the listed support recommendations.
The problem originated when I plugged the IPOD shuffle directly into the computer USB ( not using a hub), and this caused a warning window to appear saying unknown device has caused a power surge to this port, and most be removed. Prior to this event, the IPOD shuffle has worked (with direct contact with computer usb or through a powered highspeed usb hub) without issue for nearly 1 year. Any taker's on this issue? Thanks.

Hi JBR,
Go to your control panel and click on Install/Uninstall programs. Scroll down and see if you have multiple versions of the ipod updater installed on your computer. If you do, then uninstall both versions. Reboot your computer.
Next, go to the downloads page and download/install the 1-10-2006 ipod updater. Once installed, go to your start programs and select ipod updater from there. Plug in your ipod and wait a moment. If it's like mine, it'll recognize your ipod and then you can do a "restore" for a clean format.
After that, open itunes and life should be good.
Hope this helps!

prior to doing anything, you need to install the USB drivers.

External monitor not recognized (X200)

Hi,
I have an X200 with Vista
When I connect an external monitor (or projector) it is not recognized. Shift-F7 results in a message that no external monitor is detected. However, if I leave the monitor connected, put the system in standby and then resume, it recognizes the external display.
Any thoughts to how I can get it to recognize without this work-around? Thanks

I had the same problem. I think it's a vista device driver issue. Try this-
Power down your laptop. Plug in the external monitor. Boot the computer - it should default to the external monitor, and Windows should recognize it. Then, shut down normally.
Pull the monitor cable, boot your laptop regularly, reattach the cable, and give it a try.
It worked for me.

Apple monitor not recognizing keyboard

My 7 day old Apple 23" monitor is not recognizing my 7 day old Apple keyboard (hardwired, not wireless). I am using a MacBook Air. All was fine until last night.
Suggestions?
Thanks!

Some similar things but not many. I have not changed anything in the computer. Update , I did borrow a VGA to VGA cable was able to get this to work. But for the life of me I cannot get a signal from the Displayport. Also I tried a Displayport to DVI-D cable with no results. I would like to use a digital signal rather than an analog. Maybe I will try to update my Bios.
Thanks for your reply. Anybody else had this problem?

IPod nano does not charge & is not recognized by computer or iTunes

I have a 1st generation nano 1 GIG.
It appears "dead."
It is not recognized by My Computer, iTunes or the Ipod Updater (The updater asks that I connect the iPod, which I do). The iPod diagnostics through iTunes also reports that my iPod is not connected.
I have tried my iPod on 4 different machines, with one of them having USB 2.0.
I tried the following from Jeff Bryan. (I don't know if the links from his post have carried over into this post.) So I will list the things I have tried near the end of this post.
- My iPod won't turn on.
- iPod battery doesn't charge.
- iTunes 7 doesn't recognize the iPod.
- Your Windows PC doesn't recognize iPod.
- iPod appears in Windows Explorer but does not appear in iTunes.
- iPod does not appear in iTunes.
- Fast user switching in Windows XP is not supported.
I tried resetting my iPod by switching the Hold button on and off and then pressing Menu and the Select button for 6-10 seconds. I have done this over and over and over.
I have uninstalled the latest iTunes, reboot, reinstall - same problem.
I have stopped the iPod service, plugged in the iPod, but it isn't recognized by My Computer as stated in the Apple Do-It-Yourself Help. I launched iTunes - same problem.
I used the window cleanup utility, reboot, reinstall iTunes, connect iPod - same problem.
I have used the Windows ipconfig utility to change my boot parameters, but still nothing.
If anyone has any ideas, I would greatly appreciate them.
My iPod is just shy of 6 months.
I do have a replacement contract with Best Buy - but I would like to cover all the bases before I succumb to defeat.
Thanks
