Lenovo Ideapad U410: Display not working after sleep and/or restart

Hello all,
I am recently having some inconsistent display issues with my Lenovo U410 laptop i7 1TB with a Windows 8 PRO upgrade (came with windows 7).
When I press the Power Button on my laptop to put it to sleep, the Screen turns black as if it is off, but the Power & Battery LEDs on the front of the laptop remain on, as well as the LED on the power button. However, when I try to wake my laptop, there is no response on the screen (remaining black as if it is off). The internal fan is running, however I receive no feedback when "blindly" trying to input my password.
I've tried to turn the power off and back on to no avail. I've also removed the power source and held the power button for a couple of seconds and that did not solve the issue either. I've tried connecting the laptop to a screen via HDMI (since there is no other AV port on the device), but there was no signal being sent through.
This is an inconsistent issue that began yesterday 6/11/2013. When the laptop is left alone for a little and is turned on again, the display works, but after closing the lid (sleep) or pressing the button, the display fails to turn on upon awakening.
In most recent circumstances, Today (6/12/2013) I was installing a Windows update that required my computer to restart. When the update configured perfectly BEFORE it was restarting, but AFTER the restart, my internal fan began to work, but the display was not on.
Does anybody or Tech support know what may cause this inconsistent behavior? or know any solutions to this issue?

I am facing similar problem - post sleep & sometimes on touchpad event - the screen gets stuck & a strange array of gray screen comes or the existing screen's colors get distorted & the laptop gets stuck.
model - Lenovo U410; 64 Bit; Windows 7 Home basic;, Intel core i5 processor
I have upgraded display drivers but that hasn't changed anything. Any help is appreciated.

Windows 8.1 wifi not working after sleep (and other various bugs)

Hello Apple support forum, this is my first post!
Alright, so I just switched to my first mac. MBP Retina late '13. I bought it primarily to run windows, and to also of course use OS10.
My issues in bootcamp however are getting annoying. My Wifi shows up as connected after I resume from sleep, but my mac won't let me disable wifi, enable airplane mode and then re-enable wifi, nothing. The only way to get wifi to work when resuming from sleep is to reboot.
I just set hibernate when close lid on all my power modes, and basically disabled sleep for now. Hibernate works fine for now, but sleep is much faster from resume and also I'm not sure if the machine will wake up from a simple tap on the keyboard or opening of the lid, I think I have to actually boot it all over again anyways.
My other minor but still annoying issue is my titles of windows in windows are showing up as black (screenshot here)
the only other thing I was curious about was the dual-gpu functionality. I know from reading these forums it's probably not possible because of the hardware and software mesh apple created for OSX and their dual-gpu design, how it wouldn't really work in windows. I'm just wondering if anyone ever got this to work in windows maybe on the older retina MBP or older macs, or if anyone is making progress on trying to fix that in windows? I bought this laptop expecting that to work, even the geniuses at the Apple store said it would be possible, I was misled and might have second-gussed buying a 3k machine if it would only get a few more hours battery than my old Vaio. I bought this machine primarily for battery life.
I'm just remembering another tiny tiny issue. When I plug headphones in the headphone jack in windows, it doesn't automatically switch to that audio output, I have to manually do it in audio settings, is this a bug, have I configured something incorrectly, and is there a fix?
One other thing is my dpi settings, I have it set to a larger font and everything because at stock it is SOOO tiny. my question is, is there any way to smooth out text in other apps, my browser and apps like rdio look like crap unless I leave the dpi settings stock, which I basically need a magnifying glass to use (I tried that for a week lol. Not the magnifying glass tho haha)
I know I'm rambling at this point, but in the windows 8.1 camera app, sometimes my camera does this bug where it flips between inverted and normal, extremely quickly, so it looks like there are two of me. I don't know if this was GPU drivers tho, because just reinstalled those this morning and it seems to be ok so far.
also, the keyboard. I miss my context menu key, what do I need two command keys for? A right alt button, I'd rather have that be the other control button. Any way to remap these easily? what about switching Fn with control on the left, I prefer my windows button in the exact corner.
last question tho, I saw people overclocking gpu's on their retinas from last year, can you do this on the new retinas, and can you overclock the cpu as well as the gpu?
I do have to say this in the end, I am a little dissapointed with apple, I was told thst my mac would run windows like a native windows machine. I know windows 8.1 is not supported, but coming from PC's for years, and being a PC technician, I also go to school for computer engineering, I expected everything to "just work" as steve jobs once said. Well, it doesn't just work. I even had these issues in windows 8, which is supported.
Installing windows 8 was a nightmare. I had to use the forums, try for weeks to get windows 8 to finally instll the proper (uefi) way, and to get everything usable, I had to reinstall my os's twice.
Apple, if you are going to advertise a mac that can run windows "seamlessly", you need to get these major issues fixed, support all new versions of windows before they are even release, and release proper hardware drivers and support software before new hardware is released. All other Windows OEMS are pretty much required to do this to stay in business. I don't dislike OSX, I just use windows for everything I can't use Mac for, so please fix this. You're better than this, you should put a higher standard on this. otherwise, don't advertise macs that can run windows.
Thanks guys, sorry for the information overload. BTW, MBP Retina 15" 16GB RAM 512 SSD, 2.6 haswell, pretty much the max specs other than the SSD.

I have stated every issue I’ve had so far in a fairly clear and concise way. I think if you read what I wrote, it all makes logical sense as to what is going on. Windows 7/8 would work just as well on a Mac if it was supported the same way the OS is for other OEMs.
As I stated earlier in the post, I’m having these same issues in windows 8, not just 8.1, which is the reason for the post. I know the difference between supported by drivers and not supported by the manufacturer. The fact that when Haswell mbp’s came out and no revision to bootcamp for the new hardware was released to fix issues with installing windows on the new hardware shows Apple clearly Is not supporting bootcamp as strongly as they advertise.
I am being realistic on Apple having drivers early. Anyone with an MSDN subscription can download the RELEASE version of windows months ahead of the actual release, I’m 100% sure if any average consumer can do that by paying $100 and saying they are a developer, apple can do it just as easily.
You aren’t much help, you haven’t answered really anything to my post, nor have you contributed any knowledge that wasn’t clearly posted above, so don’t say anything if you don’t have anything to contribute.
By the way, my rant is directed at apple, as you can see because I am saying “Apple, if you are going to…” because this is an Apple forum on Apple’s website. It is not directed to end users, clearly.

HP SimplePass Reader Does not Work after Sleep

I have only had my laptop for a week - the fingerprint reader stopped working 2 days after I bought it. I have tried everything: removing and re-installing various drivers and software, stopping and starting Credentials Manager, unchecking the box that allows the computer to turn the reader off to save power, etc.
I have gotten it to the point where it functions when the computer is logged in, but not after sleep. It works once if you restart the computer, but after waking it from sleep it does not initialize. (no light or anything) However, if you "lock" the desktop from the start menu, the reader will log it in again. (without closing the lid or putting it to sleep)
Simple Pass version 6.0 (latest downloaded from HP.com)
Envy Dv6 7229wm
Windows 8 64-bit
Thanks

Hello hawvi,
I see that you are having problems with the fingerprint reader not working after returning from sleep mode. I would like to help with this issue but I need some information.
Can you provide the full model and product number of the computer? Here is a link that shows how to find that information.
What operating system are you using?
How long have you had the problem?

Lenovo A1 - Touch screen not working after digitizer replacement

After dropping my tablet and breaking the digitzer, I ordered a replacement digitzer from a company in China. (It took about a month to get it) After watching this video, I was able to install my new digitizer and it finally looked new again....well at least the screen!
But.....when I powered up my tablet, the touch screen wasn't working..... I emailed back and forth with the company and they told me to install drive program, and send me a link to a site with a video, this site may have contained more than the video, but it was all in Chinese and I couldn't figure it out even with Google Translate. So I started researching. I thought I would try and load ICS on it, I thought, "Whats the worst thing that could happen?" it wasn't much more than a brick at this point anyways.
I found this website that let me through installing ICS on it. I had absolutly no expectations...but IT WORKED!!!! MY TOUCH SCREEN IS NOW WORKING!!!! I COULDN'T BELIEVE IT!!!
When I was researching for this problem, there was absolutly no posts anywhere for "Touch screen not working after new digitizer". So I wanted to share my experience.

Yea you are correct.....it must be a hardware problem. You must contact service centre of Lenovo and get help from there.
You can say thank you by pressing the star left to my post IF I HELPED YOU

F3507g GPS not working after sleep/resume Windows 7

Under Windows 7 on ThinkPads with the F3507g Mobile Broadband Connection, there have been two long-standing problems:
(a) after sleep/resume, the F3507g (Wireless WAN) disappears from the Fn+F5 menu;
(b) after sleep/resume, ThinkVantage GPS does not work (forever displays Fix Type: N/A).
By searching these forums, you can find past threads about these problems, none with a reproducible resolution.
I am pleased to say that the latest driver update for the F3507g (v6.1.10.5 7UW708WW) appears to ameliorate problem (a) in that the F3507g Wireless WAN eventually re-appears in the Fn+F5 menu if you give it a few tens of seconds after a resume. This update is available from:
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-73681
However, the non-working GPS after sleep/resume is still not solved. Even though the "Wireless WAN" card is present and shown powered-on in the Fn+F5 menu, ThinkVantage GPS (2.60) is stuck on Fix Type: N/A, and the Windows 7 Weather gadget does not automatically discover the location. Both applications work fine after a full Windows restart, but not after a sleep/resume.
I have, however, discovered a work-around which restores GPS operation without a full restart:
Open Device Manager;
Expand "Universal Serial Bus controllers";
Right-click "F3507g Mobile Broadband Device" and select "Disable";
Wait for the system to settle down again;
Right-click "F3507g Mobile Broadband Device" and select "Enable";
Wait for the system to settle down again.
Now you can press Start in ThinkVantage GPS, and Fix Type will quickly change from "N/A" to "No Fix", and then onward to satellite discovery. And after a few false starts, the Windows 7 Weather gadget will discover the location.
The fact that this work-around restores GPS operation indicates that the underlying fault is a driver software issue.
The above symtoms and work-around have been verified on both a ThinkPad X301 and a ThinkPad T400s. Neither have ThinkVantage Access Connections installed. The X301, when previously running under Vista with the previous generation of drivers, did not display these symptoms: the symptoms appeared with the upgrade to Windows 7.

Actually mine works fine after applying all the updates available on T400 w/ Windows 7 Pro 64bit. I can sleep/shutdown as much as I want and the GPS works.
By the way, you have to goto your bios to reset your settings to default by pressing F9. Maybe you should try this and see if that solves your problem.
The only GPS related issue that is not fixed is the issue of dual booting into linux. I dual boot into linux, and when that happens the GPS problem re-occurs once I log back into windows. The only way for me to fix the problem again at that point, is if I go back into the bios and hit F9 again, then re-enter windows.
If I were to stay in a windows environment indefiniately, there is no problem. The problem is once I enter Linux, the problem in windows will occur again (maybe the powerstate settings by the linux kernal messes up the settings on the card).

Touchsmart 520-1047c Mouse and Keyboard will not work after sleep mode

I have an issue which I need some help with. When my computer goes to sleep the wireless mouse and keyboard will not work unless I restart, however each one will wake the system up but will not operate after that. I have tried just making the display go to sleep, both go to sleep but that makes no difference same issue occurs. The only work around I have found is going into the power settings and turning the sleep mode off for booth the computer and display. This does not solve the problem it just masks it. New batteries, unplugged and replugged the dongle, updated the bios and all drivers. Don't know what else to try. Anybody know how to fix this? Thank you in advance for your help.

Lenovo IdeaPad Flex15 WiFi not working

IdeaPad Flex 15. Changed drivers to the latest from Intel. 17.1.0.19 from 7/21/2014 and the system always drop down in a few mins. I changed the power settings so fixed the issue with sleep mode. (when close laptop, and oipen, the card was not working anymore until manual disable/enable device).
Now it works, but lost connection and need to be at least switched off and on to reconnect network.
I want a quick solution please or take the laptop back and give me more mone. I'm not able to continuously work with that device and it is pain to have it. I just feel it was really bad investment into this device.. and to know that before, never will buy it.

hi oxley
Sorry to hear about your Wi-FI trouble.
If you have the Intel® Wireless-N 7260 (Single Band, Wi-Fi + Bluetooth) combo card, can you try the following:
1. Install Version: 17.0.6 (Latest) from the Intel site:
File name: Wireless_17.0.6_De164.exe
Version: 17.0.6 (Latest)
Date: 08/11/2014
Size: 21.35 MB
Language: English
Operating Systems: Windows 8.1, 64-bit*
2. Disable the Bluetooth (see this guide)
3. Set the power management settings of the Wireless Card and the PC to High Performance (see Method 2 and 3 of this guide)
When done, do a continuous ping via the command prompt (eg. ping -t www.google.com) and observe. If you get continuous reply and no connection drop / request timed out then that means the Wi-Fi connection is stable.
More info:

2nd display doest work after sleep

So my 2nd display was working fine until i put the computer to sleep. Now it doesnt come back even if i unplug the monitor, power off the monitor then back on, nothig is working, I have to restart the machine.
thoughts?

Your Dell most likely has multiple inputs. Have you tried setting the current input to DVI?
I have a 24" Dell which allows me to switch between DVI 1, DVI 2, HDMI, DisplayPort, VGA, Component, etc. Your input is probably not the right one.
Also make sure the DVI cable is firmly connected and undamaged.

Bluetooth keyboard not working after sleep *windows8* FIX

Its pretty simple actually. It might not work for you, but let me know if it does. Untill bootcamp drivers are updated, I found that disabling the Bluetooth Network adater under Networking And Sharing in the control panel will allow my Keyboard to function again after waking up. If you find that your keyboard is still paired, but not responding when your Windows 8 install wakes up after sleep, this might fix the problem for now.
If you have a notebook, I read on another forum that if you enable Bluetooth Collaboration under the device settings in Device Manager, you can fix this issue also. Google for it if your interested.

I've noticed on mine that if it is coming out of Ssafe Sleep (you can see the progress bar at the bottom of the screen if it is) then the keyboard does take a bit to active.
This may not be your problem however just be sure you've been patient enough after waking.

Safari will not work after sleep mode

After going into sleep mode safari will not work. Firefox works fine, mail is fine. Happened after upgrade to O S x . Browser is Safari 8. How do I fix this?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Sound not working after sleep

When i connect my headphones and once my macbook pro goes to sleep, Its not giving me sound back. Even after unplugging my head phones, it is still showing head phones as my out put.
Does anyone has a solution for this issue? [it is working fine after a reboot]

Delete the sleep file using a command in "Terminal".
In terminal, type the following command...
sudo rm /private/var/vm/sleepimage
You will be prompted to enter your computer password. *Note you password will be hidden* hit enter when done.
Put computer to sleep and wake to see if problem still occurs.
