External display no longer being recognized ideapad u310 touch with Win 8.1

Several weeks ago I was able to attach a external monitor with a HDMI to DVI cable and it has been running without any problems until today when I turned on the laptop and nothing came up on the external display. Control panel only shows one display and will not detect the second display. Restarting has not help. No new programs have been added and nothing has been moved. I tried attaching a different external monitor and once again it could not be detected. Where do I go from here?

Anyone have any help or suggestions? Thanks

2nd external display no longer being recognized after updating to Yosemite

using a 2 yr old Macbook Pro 15 with 2 external monitors. No prior issues when I was using Mavericks but since switching to Yosemite yesterday, I've not been able to get the system to recognize the 2nd monitor. I've restarted the system several times and still nothing. I've also checked all connections and made sure everything was secure. What can I do to resolve this issue???

Anyone have any help or suggestions? Thanks

IdeaPad U310 touch: Can no longer enter bios after updating to latest version

I flashed to the latest U310 bios (http://download.lenovo.com/consumer/mobiles/65cn99ww.exe). I switched to "legacy boot mode" (from UEFI), in an attempt to workaround a driver issue. Now, I'm no longer able to enter BIOS whatsoever. There are plenty of forum posts by many users hitting the same or similar issues on U310/U410/U330 and similar ideapad products. But the resolutions where they exists are either invalid, or involve flashing to 65cn99ww.exe, which is not possible.
[Environment]
Lenovo IdeaPad U310 touch, Windows 8 (also tried Windows 8.1)
[What I did]
Flashed BIOS using official Lenovo bits (65cn99ww.exe). No errors occured
Enter BIOS afterwards and change to legacy boot mode (from UEFI)
[Problem]
Cannot enter BIOS to view or change any settings.
[Debugging]
Try to enter BIOS by key button sequence.
1. Tried the following combinations during bootup: F2, Fn+Fn, F10, Fn+F10, F1, Fn+F1, 'B', 'N', Fn+'B', Fn+'N', Delete, Esc.
==> No change in behaviour. I tried each many times in case the timing is important.
2. Boot by Novo button. This brings up a menu, which includes an entry to enter BIOS. However, choosing that menu entry boots to Windows
3. Reboot to UEFI firmware settings from Windows (Settings/General/Advanced/UEFI). I can choose to boot to UEFI settings, but ultimately, just boots to Windows 8.
4. Try to reflash BIOS. Fails with error 182: Version less than or equal. So reflash fails
5. Try to reflash old BIOS. Flashing fails
6. Unplug battery from motherboard for 1 minute. No difference in behavior
7. Boot with SATA disconnected.
8. Try various flashing options and alternate ways to flash. Not successful
[Conclusion - BIOS is faulty]
I think this problem can be solved easily with a slightly newer variant of the BIOS being officially released by Lenovo. If someone from Lenovo is reading, can you please open an internal case on this.
Otherwise, I'm open to suggestions from the community. Does anyone know how I can hex edit the bios version #.
Thanks
Solved!
Go to Solution.

All,
When I navigate to the U310T (touch) on the support site, I'm not finding a BIOS update.
It may be that we have removed it. The U310 (non-touch) does still show BIOS 65 available here for Windows 8/8.1 and BIOS 21 on the same page for Windows 7.
Is it possible that you have a touch model and applied the non-touch BIOS?

TS1591 my ipod touch 2g is no longer being recognized by itunes why and what can i do i have reset it and everything

my ipod touch 2g is no longer being recognized by itunes why and what can i do i have reset it and everything

If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.

My Apple ID is no longer being recognized after IOS5 update

My Apple ID is no longer being recognized after upgrading my I-Phone to IOS5. When trying to update my aps, it asks for the password and doesn't recognize it when I enter it. I've been through the entire "Forgot my ID" process, but nothing's working. Can anyone help please?

Me too my real worry is that we will not be able to download software updates as it seems to me that the original software was installed using the old ID

Okay everyone I was able to resolve the issue with my scanner.
After posting here I recalled how my wireless mouse was acting up and the step I took to resolve that issue, so after uninstalling the hp software I went to the Library/Preference folder and removed all the hp scanjet plist and all the other related scanjet files.
I emptied the trash can and restarted my computer and then reinstalled the updated driver and "walaa" I was once again able to create magic.
Well thanks to everyone.

External display no longer working

I recently purchased a Macbook Pro Retina 13" (Late 2013) model and was able to use it with my external display yesterday. Everything was working great out of the box and I was using the hdmi port on my mac to connect it to my monitor (dvi). Today though when I first turned on my mac after shutting it down for the night, my external display no longer receives a signal.
I've tested the cable and monitor with another laptop and everything is working, but for some reason just not with my mac.
I've tried resetting PRAM and SMC, and have been googling how to resolve this but have no luck. Any help would be appreciated.

So I somehow got it to work again, although it was unexpected, random and 100% luck.
I think what fixed it was that I switched off and unplugged the power strip that my monitor was connected to (I was reorganizing my cables). I didn't plug my rmbp right away though. The external monitor was still hooked up to my windows laptop. On a whim though I decided to plug the hdmi cable into my rmbp and it worked! My monitor set up also went back to how it was the other day.
I am sure that I didn't do anything on my rmbp that would have fixed it because I was just browsing internet on it. So if anyone is having this problem of where the monitor used to work but then suddenly didn't then I would suggest them to try this out. Let me know if anyone wants me to recall what I was actually doing. Good luck!
I think in the future to prevent this from happening again, I will probably unplug my rmbp from the monitor before shutting it down for the night.

Ideapad u310 touch, removed screen now computer doesn't work

I recently removed the screen from my ideapad u310 touch, hoping to connect it to a usb monitor to use as the primary display (or to my android tablet for portability). The hinge for the original screen broke and the screen started cracking so I couldn't close the screen anymore. Other than that the computer was working perfectly. Once I removed the screen and put the computer back together, I connected it to my tv using an hdmi cable. But now when I turn on the computer all I get is a green screen on the tv. Is the lcd laptop screen vital to the computer functionning or did I perhaps not connect all of the cabkes correctly when I put everything back together?

Welcome to the Lenovo Community !
I have never tried this with your model, but it can work on some laptops. Unless someone visiting this message thread has already done it and shares their experience I am afraid you will have to do a little experimenting. I would disassemble the laptop and plug in the original LCD display and then do the HDMI connection to the TV. See if the TV now has the proper image instead of green. If it does then power everything down and disconnect the LCD laptop display. When powered back up then see if the green reappears on the TV. If it does then try just having the video cable to the laptop screen connected without the laptop's LCD screen connected on the other end and try again.

RE: ideapad u310 touch hinge

so im going to have to fix my hinge myself... problem is i see multiple hinge types when i go to order. can anyone who had this problem send me a picture of the correct hinge type or even better send me a page where its on sale so i can buy it http://www.ukpcsparts.com/lenovo-ideapad-u310-touch-lcd-display-hinges-p-41349.html?zenid=0e57435dbffdf8b741deb38bd0bb7975 or http://www.ebay.com/itm/New-Lenovo-IdeaPad-U310-Touch-LCD-Display-Hinges-Left-and-Right-/181628676540?_trksid=p2054897.l4275 these are the two types .... please help

I'm not an owner of your model, but in looking over links you have provided, I believe the picture shown in the eBay sale is incorrect. The hinges pictured in UK PC Parts link would be the correct ones when compared to Page #90 of the diagram shown in your model's Hardware Maintenance Manual and the pictures shown in the additional eBay search I did. Here are the results...
eBay search:

If you are still interested in the hinges offered by that eBay seller you might want to send them a message and have them verify that the picture is correct for what they are selling.

HELP Ideapad u310 touch win 7

Hi everybody
i got this ideapad U310 touch brand new and it came with win 8, then after i bought it i installed a win 7, it was working fine but the windows was asking for a valid prodcut key, i tryed a couple and no luck , so i found another win 7 from a friend with a valid serial , i installed the fist part, restart and finish the installation and then when was about to restart again now it only shows the lenovo logo and restart ,and keep restarting from the lenovo logo.
any help please , because i dont want to install the win 8.
thank you.

hi luifej,
Welcome to Lenovo Community Forums!
If the Installation completed and the product key was accepted , Then you should be able to log back in.
It's possible that the Installation got corrupted
Try Booting in Safemode by tapping F8 when on Lenovo Logo and see if that works.
I would Suggest do another Install of Windows 7 and Try completing it again,
Note: Use a product key that has not yet been used for another computer, WIndows may detect that the key was already used and prevent you from Using It,
If you wan't to get a product Key You might want to call Microsoft and Let them know you need a retail Product key (fees will apply) as this is a different Version of Windows from the Preinstalled.
Best Regards
Solid Cruver

I have an iPod Touch 3rd gen and while it is recognized by my laptop with Win 8.1, it won't sync with iTunes.

I have an iPod Touch 3rd gen and while it is recognized by my laptop with Win 8.1, it won't sync with iTunes. It worked fine while my laptop had Win 8 but after the update, it quit syncing. Strange though, I downloaded an app directly to my iPod and when I connected it to my laptop again (for recharging if nothing else), iTunes updated itself by including the new app. I also tried syncing wirelessly. Also unsuccessful. I'm about ready to change to an alternate to iTunes if I can't get this situation fixed. Anyone else have this problem and/or a solution?

Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Featurs appin the Window Control Panel. Then reinstall all the Apple software components
- New cable and different USB port
- Run this and see if the results help with determine the cause

External Hard Drives not being recognized

I have 3 external hard drives. Had them for a long time now. I recently made only one change: I decided to start using the 'sleep' mode.
I noticed the sleep mode and external hard drives didn't get along real well, so I simply took the externals (used only for backing up data) and turned them off.
Its now been about 2 weeks, time to fire them back up and backup my data. Only one of the 3 is being recognized. The other two seem to come on, make the usual whiny noise and such, but aren't seen in the finder.
I've tried restarting my computer, turning off/on the hard drives, unplugging/replugging them from power, unplugging/replugging them into USB. I've verified connections, that kind of thing. Nada.
Any ideas on what to do to help my computer 'see' that they are there? this is a bit baffling to me and disconcerting, to say the least. I've never had problems with my computer recognizing the externals before.
Ideas are appreciated.

'sleep mode' ?
Do you mean the drives are triggered to not spin up for a period after powering on ? This is a feature designed for enormous banks of drives, so that when they are powered on, only a fraction spin up immediately, then another set, usually 12 seconds later, then another set, etc, until all are up to speed. This is reduce the power surge from spinning up 700 hard drives simultaneously in a commercial solution.

External display no longer detected

I was prompted to install the iMacEFIUpdate1.7 & ThunderboltSoftwareUpdate1.1 automatically this evening and after the update my external display is no longer being detected, before the update everything was working fine. Its connected from one of the thunderbolt ports to an HDMI port on the display
I've tried to manually install the updates again, the ThunderboltSoftwareUpdate1.1 installed again with no errors but the EFI update pkg will not run, if gives me a message saying that 'The software is not supported on your system.'
I've rebooted numerous times, tried different display ports and a different cables but nothing seems to work. Any ideas would be greatly appreciated.
(I'm also running 10.7.2 on a 3.4GHz intel core i7, not sure if that helps)

I too am having issues getting external display activated for two different animation programs. One worked for a while, then the "Full Screen" option failed. It did not work on the other animation program (Modul8 & Arkaos). I'm on MBP and upgrated today to 10.5.6 which could be the source of the problem. I don't know what other connector to get between the cable from the monitor into the computer. Also, the output window (in Modul8) no longer works, even without full screen mode activated. I've quit program, rebooted, turned off monitor.
I've another cable for video projection I may try later.
External monitor is seen by system and is otherwise functional.
Help! I've work to do. Thanks.

External display no longer working - stuck at blue screen

Hi everyone. I just don't know what in the bloody **** happened here.
Everything was working fine, I even had my macbook 13 upgraded to 10.5.6 and it always worked fine with my external DELL 2007WFP screen thru DVI cable and miniDVI adapter.
Suddenly when I got home today and plugged the miniDVI adapter, I saw the screen blinking forever at the blue screen that usually fades out to both screens with extended desktop turned on.
If I unplug the miniDVI adapter, everything gets back to normal on the macbook screen. I plug it again, I get the blinking blue screen.
Tried rebooting, unplugging everything else from the external screen, no luck.
If I boot the macbook with the external screen on and the macbook closed, then it is recognized fine and I can use it, but when I want to use both screens, it will blink again.
I need to use both screens as that's how I arranged my workspace.
Again, everything was working fine yesterday.
Thanks

Did you ever figure out what was doing this, and more importantly, did you get it fixed? I have the same thing happening to my macbook 13. It has worked fine in the past with external displays, both mini-DVI to DVI and mini-DVI to VGA, and many types of monitors/projectors. All of a sudden last week, i try to connect to my external monitor and I get the flashing blue - dark blue - light blue - repeat...
I tried the command-f1 trick to switch displays, and it sits there for a second, my desktop will flash onto the external monitor for a second, and then it'll give up and go back to the repeating blues.
I ran the hardware test, both the short and the long, to no avail.
I tried with the lid closed and an external mouse and keyboard. I tried this both from the startup and from when the laptop was already on.
Any ideas? Time to go to the genius bar?
