U520 screen flicker and random curoror movment

I have a new Lenovo U530. Periodically there is a light gray circle that appears on the bottom right portion of the scroll bar. When this appears my cursor pointer seems to randomly move. This happens more often when I'm surfing the internet. When I'm on a webpage the font size randomly changes and the cursor moves. When I get to the main Windows 8.1 screen it rapidly shutters and the screen size changes very rapidly from very small to very large.
This is super annoying and the only way to stop it is to reboot. What is causing this?
Please help.

Lion causes your system to use more resources so it will run hotter. If you haven't cleaned you iMac's dust out:
As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a

How do I get rid of random screen flicker and black screen when using a late 2013 Mac Pro with a 4k Samsung 55" Display?

I have a new Mac Pro late 2013 and a 55" 4k Samsung display connected using an HDMI cable. For the most part the display is amazing, however, I get occasional screen flicker and black outs. Can anyone help? Could I possibly have a bad video card?

4K displays take more than half the bandwidth of a ThunderBolt Bus. So you may get better results if you are careful to place them on their own Bus. This article has the explanation of which port is using which Bus:

When I was editing a picture that I reposted on instagram, I hit the edit button and then a white screen appears and randomly shuts down. I have also noticed that my iPod has been crashing about every single 30 minutes!

When I was editing a picture that I reposted on instagram, I hit the edit button and then a white screen appears and randomly shuts down. I have also noticed that my iPod has been crashing about every single 30 minutes! Please help!

The iPod crashing when editing a photo is a known bug in iOS 5.1.1.
For the other problem.
Try the following:
- A reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod.
If you still have the problem that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order

Screen Flicker and Glitch on 24" iMac, Early 2009

For a while now, my iMac has been having somewhat random display glitches, flickers, freezes, and kernel panics that can only be fixed by shutting down the computer.
Most of these screen glitches go like this: The display flickers black quickly, letting me know that an issue is going to arise. The issues that could happen are as follows:
A blue line glitch (very common)
a random artifact glitch (somewhat uncommon)
a freeze-up (very common)
a kernel panic
Let me describe these:
There are several types of "display glitches" I've been experiencing. Some of them involve random artifacts that are randomly displayed and seem to be hovering over whatever is going on on the screen–for example, once I was browsing Facebook and the glitch occurred, so a square of my browser screen was sort of cut out and stuck on the screen above everything else going on. The issue wasn't fixed until I restarted the computer. This glitch, however, wouldn't show up in screenshots. These are somewhat less common because it seems if this one happens then it either gets worse very fast and there are random pieces of my active windows all over the screen or it freezes the computer up entirely, or even results in a kernel panic.
Another "display glitch" that is far more common is a sort of line glitch. It's very strange: blue lines will outline random shapes and things all over the screen. Pictures on my browser appear distorted and videos look VERY weird. The dock has the lines and random blue pixels as well. The desktop background appears distorted. This glitch often starts with the screen flickering black and the various blue lines appearing. The lines change shape as the objects on the screen move around.The issue doesn't appear in screenshots but I documented it by taking crude videos and pictures on my phone that give examples.
Here's a link to my video of a video about a nonrelated screen glitch. I was actually searching Google for a solution but it turned out to be unhelpful, but since the screen glitch happened to be going on I decided to record it as an example. Notice how the blue lines move with the video...
Here are some pictures:
This next screenshot looks a little creepy with the armored polar bear–it's a LoL build on Mobafire. CLICK HERE TO SEE WHAT IT'S SUPPOSED TO LOOK LIKE:
---NOTE: My computer actually JUST screen glitched and froze up completely, at which point I had to shut it down and reboot. Luckily the post was saved! Just in case you were wondering how often these things occur.
This issue is getting worse and worse. I'm not sure what triggers it, but it seems like graphics-intensive programs like 3D games can trigger it–especially, it seems, when I toggle on and off fullscreen. It looks like it could be a graphics card issue, because if it was a software problem it would seem like it should show up in the screenshots. It's sort of an underwhelming graphics card, but meh. My mom is having a panic attack and backing up everything on the computer and we're thinking about just reinstalling OS X altogether.

When I move my mac the screen flicker and must be rebooted

when I move my mac the screen flickers and goes blank then must be rebooted. Crap

Hi , and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
And sorry to report that OSX is more Widows like than ever, but….
If that doesn't help Reinstall the OS.

X300 partial screen flicker and solid colored lines

Hello all. Just opened my X300 tonight to find the lower-left quadrant of the screen flickering and some colored lines in the upper left-quadrant. The right half of the screen is viewable but pixelated. Anyone know if this is fixable? Loose cables, inverter?
thanks.
Solved!

Screen flicker and trackpad issues on macbook pro 8 2

Hi I have a macbook pro (8,2) 15 inch with a high rez anti glare display. The display stared to flicker after living my computer open in arch for about 30 min. I tried rebooting and it even started happening in the boot screen and in mac os x. The last thing I did before it happened was setup pommed in arch and leve my computer open.
Also this has sort of been asked but my question is a little different. I am trying to set up my multitouch trackpad. I installed mtrack from the aur but changing the settings does nothing. What I want to accomplish is this. 1) I want to right click by clicking (not tapping) with one finger in the button right corner of my trackpad. 2) I need to disable tap to click!!!! 3) I want to be able to click the trackpad with my thump and use my index finger to drag instead of only my thumb. for example I want to click on a window border with my thumb and move it around with my index finger while holding down my thumb.
Any help would be greatly appreciated!

Glad you figured it out. Sorry to see no one else chimed in.
I have arch on a macbook as well. I have never seen a need for the many elaborate packages which claim to make these things work. If they're working then stick with it - but if you need another option, I've had great luck with simply properly configuring synaptics:

Screen flicker and delay in texmaker (possible problem w\ qt5-webkit)

Long time reader, first time poster. Never needed to post a problem before because of the amazing amount of assistance already offered here.
I have a minor problem (annoying but could live with it), and so far, I can't find anything on it. Moreover, I really don't know what error logs to consult about it or how to go about finding the source of the problem. So, I apologize in advance for the lack of information on the problem, but part of my question is what to look for.
Had a machine that was a bit behind on updates (about a year), went through all the news posts, updated as required, everything went fine, and everything is still working. There are two applications, though, that seem a bit buggy: texmaker and calibre. Whenever I open either up, it takes quite a bit longer than it did prior to the update, and my screen starts to flicker a fair bit. Eventually, both open up and run just fine, but the delay and screen flickering troubles me. I don't use calibre often, but I use texmaker all the time. So, I would like to see if there is anything I can do to sort this out.
I checked the general logs from journalctl and dmesg to see if there were any errors, and there wasn't anything. I also checked the xorg log to see if there were any errors there, and again, nothing. The only dependency the two programs have in common is qt5-webkit, and that was installed with the last update.
Could anyone recommend a way to figure out if that is the source of the problem or find more information about why it is happening?
Thanks in advance, and if I have violated any of the norms of posting, feel free to reprimand me firmly but gently; it is my first time after all.

MBP (early 2008) Screen flicker and line distortions

Hi there,
My macbook pro has been running fine for the past 3 and a bit years, but yesterday this very strange issue started occuring.
At random times, the screen with start flickering quite quickly and then random line distortions appear on the screen. After a minute or 2, the screen freezes but I can move the mouse without being able to click on anything.
So then I have to press the power off button to shut down the computer. Once I turn it back on, there are lines and distortions all over the grey screen except on the Apple logo.
Next time it happens, I will try and save a photo of it.
In the console, this seems to be what happened. I must admit that none of this makes sense for me.

Macbook Pro 15' 2.2Ghz 2gb RAM early 2008 Mac OS X (10.6.5)

From what I've read on different posts regarding video card issues and the early 2008 15" MBPs, or "affected models", Apple seems very selective at what they'll honor for repair. Hopefully my MBP will be repaired under this recall, but am not holding my breath.
My 15" MBP (early 2008 Penryn) has developed video card issues I suspect. It doesn't do the dark screen as others have which Apple is more likely to repair under the recall, but random batches of lined patterns show up on the display, it will blink sometimes, then it will totally lock up forcing a hard shut down with the power button.
I took it into a local Apple Authorized Service center, they ran the NVIDIA test on it which it passed, showing that the "known" defect wasn't the issue with my computers video card. Well something's screwed up with the video card most likely. They recommended taking it to the Genius bar at the Apple Store which I plan to do. It's less than 3 years old, Good grief!
I've been an avid Apple user for over 16 years, and have hardly ever run into hardware issues. Guess I've been lucky. But how Apple will handle my MBPs issues is unknown to me. Hopefully it will be positive, but am not holding my breath.

MSI GS60-2PC Screen flicker and horizontal black lines issue

After about 2 weeks of using my GS60, I began to notice that the screen sometimes flickered, and on other occasions horizontal black lines would appear. I have updated my GTX driver to the latest version, and I haven't been able to find any help on the net. Does anyone know how to fix this issue?

Hi!!! I'm Manuel from Argentina. I bought a MSI GS60 in miami 5 months ago, and... I HAVE THE SAME PROBLEM!! sometimes mi screen is flashing and appeared horizontal lines (blacks).
There's no solution for this problem? it's a very expensive laptop.
I hope someone can help.

Why does ipod screen flicker and shut down?Possibly need new battery?

Ipod screen flickers, but music still plays. Then it will shuy down. I ahve restored it , but still does this. My 9 year old lives on this ipod, he is going through withdrawal now! Possibly new battery? Thanks

Might as well be a hardware defect, especially if you can still listen to music after the screen shuts down.
To make sure it is not the software, set it up as new device, without using the latest backup afterwards.

Screen flicker and crashes.

My iMac had never crashed in the year that I have had it up till about a week ago. Now three times, my computer has become unresponsive, with the screen flickering. I have had to hold my power button to use it again.
I have reset the SMC, PRAM and run RAM, Graphics tests and SMART test. All passed brilliantly, the only concerned being a slightly slower spin up time, but nothing serious.
I am running 10.6.6, on Late 2009 21.5inch iMac, 3.06Ghz Dual-Core, 4GB RAM.
Thanks.

One good generic troubleshooting step for this is to run Applejack.
Download:
http://sourceforge.net/projects/applejack/
Article on using:
http://reviews.cnet.com/8301-13727_7-10334620-263.html?tag=mfiredir
It runs in single user mode. After installing (you won't see it in the Applications Folder) hold CMD-S at startup. You will get a black screen with MS-DOS like text. Just follow the prompts: type in "applejack AUTO" and it will run through the following:
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
You can also run tasks selectively and for specific users by typing in "applejack."
The first reboot will take much longer than usual, as it rebuilds caches. It may take several restarts to see the benefits. Because of the deep cache cleaning in AUTO mode some applications may tell you they are being opened for the first time.
I would also run the Hardware Test in extended. Disconnect all peripherals except the Keyboard and Mouse
http://support.apple.com/kb/ht1509
On your Mac, you can get to the Hardware Test simply by restarting holding down the D key.

Is there any way to fix my iphone 4? The screen won't stop flickering, flipping the screen backwards, and randomly turning the screen white, red or black? HELP!

I don't know if it's a hardware issue, software issue or what. If replacing the screen or other parts would help? Or if the phone is done for? Just really desperate! I don't know what to do! I haven't ever dropped the phone or had any water damage either... Please help!

1. Try doing a hard reset:
Press and hold both the Home button and the Sleep/wake button simultaneously for about 15 seconds and release when the Apple logo appears.
2. If that doesn't solve the issue, backup the device and restore it as new.
In that case, use: http://support.apple.com/kb/HT4137
NB: set up as a NEW device because a software issue will be in the backup. If the issue persists after restoring as new, you should offer the device for service.
If you get specific error messages/codes in iTunes when updating/restoring, check this: http://support.apple.com/kb/ts3694 for causes and solutions
Good luck

Macbook air: Screen flicker and speaker makes wheezing

1. I've noticed that images like this (http://bit.ly/RKNx2r | http://bit.ly/8LTYpl) are flickering on my display. Waves become more visible if brighness is turned to max. I opened the same images on the identical mac, and there were no waves.
2. When the volume is set to maximum, right speaker starts making wheezing. If to press and hold the right side of the keyboard, wheezing almost disappear.
Is there any solution on these issues? If no, should I contact the service center, or these cases are not covered by warranty.
Thank you in advance for your help.
*Model: MacBook Air 13'' (MD231RS/A)

I didn't bother because I custom configured my 11" to fully spec it out. I called my local Apple store just to see if they carried the fully-spec'ed ones and they said they only carried the base configurations.
So I called AppleCare and explained my problem and I did tell them it was hard to reproduce it and that there was no rhyme or reason to when/why it was happening. I told them it's happened when all I had was Safari open to browse the web and it's happened when I've had a bunch of things going on at once too. In the two days I had it, it happened about three to four times. Far too often for me to just ignore it or hope it will go away.
They were very nice about it and very apologetic that I was experiencing a problem and they are classifying it as DOA. They emailed me a FedEx label for 2-day shipping back to them and will overnight a new one once they receive mine back. Of course, I'm disappointed having to go about a week without it but thankfully it's not my only Mac.
Good luck to you but if this is a problem with some of the units, you probably won't have an issue getting it exchanged. If you do have a base configuration one, I'm sure you could try an Apple Store too.

Any solution for having daily screen flicker on my 2.13GHz 13" 2011 Macbook Air (running 10.6.8)???

well, the title says it all...I see on the Macbook Pro support threads that this is a continuing issue for that model and people seem frustrated that repeated replacements of motherboard and/or displays are not solving the problem.
I can still use the computer but it is a little disconcerting to have the screen flicker and it seems to be happening almost daily now whereas it used to be more of an occasional thing...
I run Onyx and fix disk permissions and clean out various caches at least once a month...but other than that, I just use the computer for low-intensity tasks of word-processing and web browsing mostly...
just wondering what people have done with this problem?
Thanks,
Eric

I finally found a solution. In about:config, under browser.sessionhistory.max_entries, I changed 5 to 20. End of problem.
