Lenovo P/Y/Z Series :: Screen Brightness Flickering When Z570 Plugged In
Jan 5, 2014
When plugged into the adapter my Levovo Z570 screen flickers between bright and dark when on certain webpages or doing certain tasks. I have changed the battery and this makes no difference. This doesnt happen when on battery power.
Â
Note that the brightness is flicking between the battery brightness setting and plugged in brightness setting. So if there is a large difference between the two the flickering is very noticable and distracting. If I make the battery brightness the same as the plugged in brightness the flickering doesnt happen.

Loving my Yoga 13 so far have had it since Oct 26th when it was released. Like everyone else I had some issues with partitioning yadda yadda yadda, got that taken care of, but lately I've noticed that my screen brightness seems to flicker, ALL the time, when switching from program to program if the color changes on the screen I notice that the brightness changes as well in noticeable increments. I have the automatic brightness setting set to OFF, so I can't imagine that's the reason.

Just received my new X1 model# Â 20a70037-US last week and right out of the box the screen was already flickering. When the laptop is booting up in the POST screen you see a bunch of little white dots all over and as soon as you get to the windows login screen the flickering begins. Just like on this video I found online [URL] ....
Â
I uninstalled the Intel drivers and now it's flickers less and the laptop is somewhat usable. I should be receiving my replacement unit this week, can't wait to have this laptop working 100%.

My W530 laptop is new. I finally got it all loaded up and ready to work with and then I started to get screen flickering issues. The screen will flicker all different colors and then it will restart the computer. The computer will start up and act normal. I have video of the issue.

The audio in the video is not from the computer. [URL] ....

I have an S440. I've had it for one week. Two days ago I downloaded the Windows 8.1 update from the store. Since then, when I start up the computer, it doesn't even taken me to the 'sign in' screen. There's just a black screen. When I move the cursor, it briefly appears, flickers, then disappears again.
I understand this is an issue with the graphics drivers. So I ran Windows in safemode and disabled Intel R HD Graphics family and AMD Radeon HD Â 8600 series graphics drivers.
This, unfortunately, hasn't fixed the problem. It still boots to a black screen with an occasionally flickering cursor. I'm currently running in safemode.

I bought an Ideapad Z570 a while ago and everything ran as it should. But the last couple of months (probably the last 5 months) my laptop has been running extremely hot. When I say hot, I mean it often reaches temperatures of 95 degrees, sometimes exceeding that to 98 degrees. What could possibly be the cause of this?
Â
I've cleaned out the processor heatsink and applied brand new thermal paste to the processor and heatsink, yet it still runs extremely hot. I've also cleaned out the blower fan and ports to ensure no dust is stuck in there.
Â
I am doing intensive work in Visual Studio, but the project I'm working on is not really that big. I've been working on another project (which is desktop and not web-based) and my computer *seems* to be ok, but still reaching 85 degrees easily on a build. It's frustrating as I don't know how long this system will run before crashing completely because its being pushed to the limits. Z570, Core i7 ...

So I use an HDMI setup to connect my laptop to my surround sound, which is also connected to my television. I only use the hdmi for the audio, but no matter what I do, I get this wierd horizontal tearing on my laptop monitor whenever I use it.

My Lenovo z570 will not boot from CD. Â I have the system recovery CDs and another bootable CD that work in another Lenovo so I know the discs are fine. Â The boot order is set properly (CD first) and even hitting F12 on the boot up and selecting the CD drive again doesn't work. Â The drive does work - I can burn and play CDs. Â I uninstalled the drive and reinstalled and updated the BIOS to the latest. Â I see others with this problem have been advised to change UEFI or Secure Boot setting but these options are not available in my BIOS.

I recently bought an IdeaPad Z570 and re-installed Windows 7 completely. I installed all the necessary drivers and software available on the Z570 drivers download page, including the Lenovo Energy Management Software.
The following software were not installed as I do not have any use for them:
Intel Matrix Storage Mgmt, Bluetooth, OneKey Recovery, McAfee, SRS Premium Sound
Â
Everything is working fine except the One Key Theatre button. When I press it, nothing happens. I did some research and found out that the key should be enabled by the Energy Management Software, but it is not the case.
There were also some posts regarding a stand-alone One Key Theatre driver, but I cannot find any such thing on the Z570 drivers download page. Just to confirm, I do not have any "unknown device" in the device manager and the version of the Energy Management Software I installed is the 6.0.1.6 from 2011-03-29.

My Ideapad Z570 has been doing this for some time - the screen is black, lights are on, and won't wake up. I inevitably end up turning it off, so I lose my work.
I've delayed the sleep mode to reduce the number of instances...

I own a lenovo ideapad Z570, and want to upgrade to a larger HDD(from 600GB to 1TB). The only thing bothering me is the "OneKey Recovery".
So, my question is : How do I make the OEM and Recovery partitions, just after installing windows7 on a new(blank) HDD to facilitate the "OneKey Recovery".

I used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again.

For some reason I can't change my screen brightness anymore. I've already tried a HD 4000 driver rollback to version 9.17.10.3223 and I also disabled "adaptive screen brightness" at the power management. For some reason I can change the brightness by using the "microsoft basic display adapter" driver instead of the HD 4000 but that isn't a real solution.

My lenovo G505 recently had to be reformated because there was a blue screen that came up one day that said there was problem with my PC and the error was critical_service_error, something like that. So my dad had to reinstall windows 8 for me using a cd he had that didn't come with the computer I don't believe. So now for some reason my screen brightness isn't adjusting and it's driving me crazy! It's staying on full brightness which I hate! I tried changing it from the personalization screen and nothing happens.

my laptop started acting REALLY weird about a week ago. While I am using it, seemingly at random, the screen 'flickers' and freezes up, and the only way out is to hold the power button to shut down, and then restart.
I have included a picture of what it looks like:
I also noticed that the speakers sort of emitted a 'staticky' sound as this happened, although this could just be because the computer stops processing the sound data.
Anyone ever experience anything similar??? What to do?
Also if I check the Windows Event Viewer after restarting, it logs nothing at the time of freezing, no errors or anything.
The laptop runs sort of warm, but never part 66°-69°C
It has: Windows Vista SP1, AMD ATHLON X2 1.6, and 2gb ram.

I just got me a W540 with docking. It is connected with two Samsung 24inc screens. They are connected with two display ports kables from the docking. I also have a wireless logitech mouse and keybord. And a Jabra headset connected.I have reinstalled it with windows 8.1 And now I have a serious issue that both screens turns off randomly while I work. They go black for 15 sec. And then re-appear. It seems like the computer looses all USB connection also while this happens. I sometime get an error msg. saying that I connected a USB device that cant be recognized. But most of the time nothing happens.
All 3 of us at work who has a W540 has this issue. So it must be known by Lenovo. I have an ongoing case with the support. But dosnt look like we are getting anywhere. They gave me this to try: URL...We think it could be a driver issue with the USB or that the computer is swiching between the Intel and the Nvidia gfx card.I think I have tried about everything, but can not figgure this one out. I have all the latest drivers from Lenovo installed. Tried to use a wired mouse and keyb. no change, tried with a DVI and Displayport to the screen. No change.

Here is a link to Lenovos System report on my W540. URL...

I have a fairly new y510p (about 2 months old), haswell processor intel HD4600 onboard and GT750M (non SLI model).Â
When connecting latop to external monitor via VGA connection, I can see the image but it looks terrible, horizontal blue lines and flickering. I don't have any option to change the refresh rate, since Windows 8.1 identifies monitor as being 60mhz (other sources work fine on that frequency).
Â
I've tried 2 different LCD monitors, 2 different VGA cables and get same result.
Have latest drivers.
Â
HDMI output works fine. Yet not uncommon for me to need to give a presentation at a place with older equipment where I must connect via VGA.
Â
Before I call support to take laptop in... any one else has encountered this problem?
Â
Is there a way for me to force the GT750M to be used for external output? I have tried setting in NVidia control panel (default NVidia to maximum performace and Intel is still being used for projection output).

My Lenovo E440 screen flickers when I plug or unplug the AC power charger. I think this happened after I installed all the drivers. This doesn't occuer when the windows was still 'fresh-installed'.
Â
I read on other thread that this also happened on other machines and I think the cause is the same, the refresh rate change from 60Hz to 50Hz when I plug the AC power and then it goes back to 60Hz when I unplug the AC power. So I plug the AC power then change both refresh rate to 60Hz. It went fine when I unplug the charger, but when I plug the charger again the refresh rate for while plugged in change to 50Hz again no matter how I try (so it flickers again when I plug the charger again).
Also, I am using Windows 8.1 Enterprise Evaluation and I've installed the latest Windows Updates, Lenovo System Updates, and Nvidia driver update.
Â
My question is:
1. Is this software error or what? If it is software error then shouldn't this occur on all user?
2. What is the difference between the display refresh rate? Which one should I use (I though higher refresh rate is better)? Why does the refresh rate change when I plug/unplug the charger? If I remember correctly AC power source is 50Hz, does it related to this problem?
