Lenovo G585 - wifi dropping and video freezing

Hi all,
I bought this Lenovo G585 (Win 8) in January this year, and over the past few weeks some problems have been developing. When I move the laptop, either the video I am streaming freezes, or the wifi drops, or both. Sometimes, even after 5/6 restarts, the laptop will not be able to find the wireless networks and I will have to shut it down, remove the battery, replace the battery, and turn it back on - and for some reason this works!
When I say "move" I literally mean I can be sitting on the sofa and move the laptop from beside me up onto my lap. The problem occurs when I transport the laptop between rooms, too.
I've updated the drivers, changed power management settings, updated my antivirus and run scans, all to no avail. What can I do next?

hi nikitgr,
When Heavyload is stressing the CPU @ 100% load, the CPU clock speed should reach 1.4Ghz as this is the specifications of the processor. (the image below only shows half). As far as I know, you should be getting 1400Mhz per core on 100% load.
If you see the same values above after running Heavyload CPU stress test, I recommend you report your findings to the Lenovo support team as to check if this is a limitation of the unit as per design or if there's a BIOS fix to correct it.

IOS 8.1.2 on iphone 6 Wifi drops and doesnt reconnect

Hi,
I had the an issue with wifi dropping and not reconnecting automatically on my iphone 6 with ios 8.1.2
The wifi was disconnecting every minutes even when the screen was not locked. I had to go back to wifi settings and reselect the network I want
I tried all the tips available (forget network, reset network setting, reboot phone, disable location, disable air drop/bluetooth, etc)
This was happening mostly in hotels with annoying DNS that redirects you to a web page to login with name/room # so changing wifi router settings was not an option
I finally set up static IP adress as mentionned in another post and now my wifi is stable for 3h (and reconnects works too)... thanks
https://discussions.apple.com/thread/6554548?tstart=0
I have resolved this issue on my new iPhone6 as follows. My router is a fairly old Belkin in this case.
1) on iPhone in settings, WiFi, forget this network
2) select the network again and select the blue i button
3) Log in to your ADSL router from another device and note network and DNS settings
4) on iPhone reconfigure using Static settings rather than DHCP (thats what I did anyway)
5) Log in to your ADSL router again and restart it or power it down and up again
6) on iPhone reconnect to the WiFi when it restarts
Now everything seems to be ok with the iPhone connected and staying connected.
However this is more a patch than a fix because when I leave the hotel (or any wifi network), the router will assign my static IP to someone else end when I come back it wont work anymore,
My guess is that IOS 8 has problems reconnecting to a router when a new IP address is leased.
The fact that the signal is weak might also affect the frequency at which the ip is renewed
FYI, I have always been a android user and just switched to apple... Not impressed. Hope this is fixed shortly

Jay,
I've tried most everything as well (including new router before I realized it wasn't our iphone 5's but IOS 8 updates. After turning off LTE and Data Roaming in the Cellular settings, things work much better. WiFi stays connected. Have since re-enabled LTE and it still works. Tried a dozen other "recommendations"; it may have been a combination of things. Still not blazing speed, but tolerable. Just wish 8.1.3 had the fix (from what I've seen today, it's not fixed). Be glad you're not having the SIRI hands-free problem; she won't connect calls in one car and has problems connecting in the other car. About as many have this problem as the wifi snafu that came with IOS 8.

Playback problems and video freezes due to plugins being used on video clips?

I am editing with Premiere, and dealing with playback issues and video freezes as I apply plugins to each video clip. Not sure how to fix this problem. I am a mac user, but I cannot upgrade my graphics card, so I am wondering how to fix this issue.

Hi,
More info will be needed to help. Please refer to this post.

FCP X / Motion 5 Drop Zone Video Freeze Frames Only!

Hmmm, well, I've followed the other discussions here regarding what appears to be an on-going issue with videos not playing (freeze frame only - usually the first frame of the clip) in a Drop Zone. I'm using the latest versions of both FCP X (10.1.1) and Motion 5 (5.1). I created a video generator in Motion with 15 drop zones for use in an open for a project I just started on. These drop zones are sliding left and right in three bands across the canvas. I can't get any of them to display moving video. I've used drop zones before and had some success with getting video clips to play in them, but in this case I'm batting zero.
Has anyone found a way around this problem? I may just import the videos into Motion and render them there since this open more than likely won't ever be used for any other project; nevertheless, I'd like to be able to use the Motion 5 template as it was designed to be used.
Thanks.

The good news, Russ, is that I've made some progress! To say that using Drop Zones can be a bit quirky is an understatement! Nevertheless, your Pro Res hint seems to have fixed my issue. I've been recutting the clips from the master archived files and saving them as Pro Res 422. The file size is considerably larger that the H.264 files, but since it works I guess I won't argue that point! :-)
I need to do a bit more investigation of this next point, but it also seems as if I need to move a frame or three into the clip before inserting it into the drop zone. I had just been taking the clip and dumping it in as is. When doing that I noticed that in some cases the clip either didn't play (freeze frame) or it started at some random (or at least what seemed to be random) location within the clip. However, since I moved the start point in 2 or 3 frames (end point doesn't seem to matter) so far, at least, the clip plays every time and starts from the proper point.
I don't know if this mattered or not, but I completely deleted the library with the project and event that I was originally trying to edit to. Since it wasn't working anyway there is nothing lost and I felt it was worth starting the project "fresh", so to speak.
So far I've only re-clipped and inserted 5 of the 15 drop zone videos but for now, at least, they are all working!
Thanks again for your help and suggestions.

Wifi dropping and slow when external USB hdd connected

Hi,
I have a problem with Wifi connection in my Macbook Air 2014 running Yosemie 10.10.1. I have USB hub, which is plugged to power and I have connected external sound card, Apple keyboard and my external HDD (I used it as Time Machine) to it. Sometimes my Wifi starts dropping and internet is extremely slow, but when i unplugged external HDD, everything seems to be fine. I've tried 3 USB hubs, but still the same problem.
Does anyone have similar problem?
Thanks for any advice.

go into system prefs -> startup disk and select the disk with os x on it. that should solve the problem

Wifi dropping and NEVER working

I have read many posts on different users having their Wifi working for 5-10 minutes, and suddenly disconnecting, and I have tried all the methods that others have contributed, but somehow it doesn't seem to work for me.
Here's my issue: I have an iPad 1, 64gb, with ios5.1. Now, on the top left of the screen, the Wifi symbol is shown, but I can never get it to connect to the internet. I have tried bringing it to different places, and the Wifi always works for maybe 10 minutes, and it drops. When I try and connect it back to the Wifi network, it never works ever again. For example, I go to Cafe A, wifi connects for 10 minutes, drops. I try and connect it again, but it doesn't work. I go to Cafe B, same problem happens again. Then I go back to Cafe A, and the Wifi will NEVER work again.
I tried forgetting the netowrking, rebooting the thing for dozens of time, restarting it to factory settings, restoring it, backing everything up and just about a dozen methods, but i never seems to work. But all the other devices on my house connects perfectly to the Wifi network, so I'm pretty sure it's not my Wifi problem. Like I said, there's the Wifi symbol on top, but it can never connect...
Help please? It's really grating on my nerves, and I haven't been to use my iPad for the past 2 weeks.. ):

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Intermittent problem after launching Premiere Pro CS6.0.2 - audio pitch dropped and video staggering

Intermittent problem after launching Premiere Pro - all audio is lower in frequency by very noticeable amount and video keeps dropping back a few frames every few seconds, apparently trying to keep in sync with slower audio.
This does not happen consistently, perhaps every 5 or 6 launches. Otherwise program works normally after launch and sometimes a quit and relaunch will fix the problem.
Have submitted bug report but wondered if anyone else having the same problem?
Mac OSX 10.8.4 iMac 3.4 Ghz Intel Core i7 32GB

Well if i do that, the video will raise up GBs larger (and that is really bad).
Why is it really bad?
Its a fact of digital life. High datarate = quality.
example ...even the Youtube preset is in the 8mpbs area.
...and you are exporting 1 hr 35mins of media.

Audio cuts out and video "freezes" every 10-15 seconds

So I recently switched to Verizon (about 2 weeks ago) for internet and tv. After about a week (with no video or audio issues), I decided that I wanted to get a DVR. So they shipped me a DVR Set Top Box - model is CHS 435HDC.
When watching live TV the problem isnt THAT bad...every 1-2 minutes the audio will cut out and the video will pixelate for about 1 second, and then it continues right along.
When watching a TV show that I recorded on the DVR it is REALLY bad...basically unwatchable. The audio and video will cut out briefly every 10-15 seconds, then it continues along normally for another 10 seconds or so then it cuts out for a second and continues again.
Obviously I'm going to ask for a different DVR to be sent to me but if it happens again with the next box I may just cancel and switch back to the "other guy". This is a pretty bad start to what I thought would be a new and better experience. (Im not even going to go into the horrible on-demand menu system.)
Wondering if anyone else has experienced this problem before with their DVR?
Thanks!
(Dont know if it matters but I am in Maryland)
Solved!
Go to Solution.

Generally but not always pixelation and picture break up is an issue with the signal to the set top box. Sometimes it's as simple as a loose coax cable, or the connector has come loose from the cable itself. There are other causes, but those are the easiest to start checking. I have sent you a private message to your forums inbox.

Mac Os 10.6.8 Crash and video freeze, Mac Pro

Hi,
I just installed Mac OS 10.6 on my old Mac Pro, early 2009 (8 gib of Ram installed). I still have my old Mac OS10.5.8 on another internal boothable disk.
It went well the first day or so but now I'm experiencing some major video problems: picture of the desktop keeps freezing, videos are crashing in Firefox 30 with Flash 14 plugin, etc. I have 2 internal identical video cards and 2 separate monitors (NVIDIA-GT120). Here is a picture of what's happening:
I have installed upgrade for FireFox and Flash Player plugin 14.
I've tried to deactivate Flash option for "Accelerated": nothing is changing, the problem is still there.
Everytime a have a window that I move from one monitor to another smear and freeze all over on both monitors.
I have QuickTime 7 and QuickTime for mac OS 10.6. I want to keep my older version because I have Quicktime Pro.
Where should I start, I'm no expert, thank you in advance to explain it to me in a simple manner if you answer to that post.
Please help,
Thank's!

Thank you for answering so promptly,
I already made a backup with TimeMachine of my new and original files of Mac OS 10.6 system.
May I point out that I've just installed Mac Os 10.6 as an upgrade of Mac OS, from 10.5. I have now Mac OS 10.5 on one boothing disk and Mac Os 10.6 on another boothing disk. I can wether rebooth on one or the other. I upgraded to my new Os from a clone copy of 10.5 to 10.6 on a different disk: I'm aware that my new Mac OS may be not be as clean as it should be.
I also did all the operations you where mentionning such as disconnecting all non essential peripherals (even my main monitor) then power it up again. I also reboothed in "Safe Mode" and started again in normal mode afterwards. I've even zapped the "P RAM". I even did a "Repair Permissions with "Dislk Utilities". Nothing of that nature have resolved the various issues that I metionned in my previous Post.
"Isolating an issue by using another user account"
Thank you for the link, I shall read it carefully and thoroughly. Yes, I have tried to logged-in as a new user before your Post. I think this solution helped afterwards.
I don't use these options often, I'm the only user and I'm not that familiar with all these options. I've tried to share some folders or files and also tried to setup an automatic password but I was not that very succesfull. As this article is mentionning: the main idea is to "check if the Mac OS is behaving as expected" in a new user account.
The answer to that is a positive "yes" and I did regain a better control of my Mac OS new system afterwards.
I did not understand at first your expression "If Back-to-My Mac is selected in System Preferences, the Guest account will not work". Reading a little about it, I think it has to do with an "iCloud feature to set up a network of Mac computers that you cant then access remotely". I don't have an iCloud connection/account installed/set-up. I only expremimented with that option once or twice many years ago with my iPod so, I,m not familiar with that option.
"Deleting/disabling the third party applications after a restart by using the application un-installer"
Since I'm not a newbie on the Mac, I know how "Third Party's Applications/utilities" may really mess up an OS and make it behave in unusual ways sometime... I did find some of them installed in the menu that where messing up my new Mac OS. I deleted/deactivated them completly and reinstalled them one by one, carefully reboothing my Mac between each new installation. Some upgrades where installed for some.
Question about User Account vs. System's Files
Can I delete certain presets and/or preference files only stored in my "User Account" but should I never do this with files stored in the "System Folder" or the "Main Library"? Sorry, I'm an "Older Guy" and I'm used to older versions of Macs... Thank you for suggesting any good updated documentation on that matter.
Which Quicktime to use with mac OS 10.6: 7.6.6 or 7.7?
This is not clear at all on Apple's Web Site. I've downloaded and installed both. Maybe this is my problem. I wish Apple would more clear about it for those like me who want to use Quicktime Pro: 7.6.6 for Mac Os 10.6 and 7.7 for Mac Os 10.5???
As for now...
My system is behaving better and it' also much more stable now, thank you! All the suggested steps have been made to to resolve certain issues.
But not all...
I've still have the problem with QuickTime 7 and Flash 14 plugin when I browse and watch certain videos on the Web after a certain time. It's still very annoying when it's starts: I get an all smeared up display of my desktop afterwards (as shown in the above example in my first post). Restarting my Mac resolve's it for a a while only... It seem's that there's a problem with the Video Ram stored when Quicktime/Flash 14 are used? They freeze the System's process who is trying to erase the old data and prevent's it to replace/refresh it with new data on screen...
Thank you for your time and looking forward to read you,
Robert Marchand

Green screen and video freezing while maximizing videos playing in iTunes?

After a year-and-a-half of seamless operation, iTunes started malfunctioning yesterday. When trying to play a video (either a TV show or a music video), the video will often freeze when I hit command-F to maximize. The audio keeps playing just fine. Sometimes I'm able to get the video running again by hitting escape and command-F a few times, and by hitting space bar repeatedly to pause and unpause. Before starting to work, iTunes displays a green screen for a half-second.
My system is at 10.5.8 and my iTunes is fully updated. My computer is an aluminum-unibody MacBook Pro 15".
I have tried turning the computer off for a while, reinstalling iTunes, and switching from discrete graphics to integrated graphics, all without any improvement. I doesn't happen every time I play a video or a TV show, but it does happen a majority of the time, and it often takes 10-20 seconds of fiddling to get the video to play.
Any ideas? I'm stumped.

I've been having the same problem as you Mitlov. This is one of the reasons I always get a bit leery about updating my current version of iTunes, iPhone, or iPod. Something always stops working amongst one or more of them. Two years ago I updated iPod and I remember it took a month before I could get the iPod to work again. If you hear about a fix for this problem (besides just buying Snow Leopard) please post it back in the discussions. There are a lot of people who will benefit from it!

Sound and video freeze up intermittently on MacBook Pro5,4.

Hi, I have a MacBook Pro5,4 labtop, with a 2.53 GHz processor and 4 Gb RAM. In the last month I have started having problems while watching videos or listening to music on my labtop. It doesn't always do this, but often the sound/video will start freezing intermittently, somewhat like when streaming and your internet connection goes in and out. However, I am still able to do other things on my computer like surfing the internet or opening documents. I am wondering if anyone would know whether this would be something with the graphics or sound cards before I take it in to be fixed. Unfortunately since it doesn't do it all the time, I am afraid that the techs might not find anything wrong with it and the problem won't be fixed....any ideas?

Hi Glo H,
yes, you are correct on all counts...
The way I work is that I cut & edit the clips and their music in iMovie 06, then "share" it with iDVD, and create a disk image. The preview in iMovie 06 is fine, and there is no sync-ing problem. I then preview the DVD in iDVD, before I create the disk image, and there is not sync-ing problem there either. After this, I insert a blank DVD, open the disk utility, and burn the disk image from there. Viewing that DVD is the first time in the workflow that I'm seeing this problem.
I suspect this is to do with the very large files I'm fiddling around with: a 90-min DVD (from my 30 clips or so) had a progressively worsening sync problem, whereas two 45 minute DVDs had no problem on either DVD. And since I'm recording in HD, the 90 min DVD is easily 60-100 GByte on the hard drive... (and this suggests that I can avoid sync problems by having smaller films, but it still would be nice to figure out what is going on here?)
Any help would be nice.

PS I'm posting a link to the iDVD folks as well as I think this is a problem with iDVD, no iMovie?....

Wifi Dropping and No help... Except to Transfer to Billing to Cancel (then disconnected)

I've been a loyal customer for over 20 years, but this is just too much. Thursday my wifi started slowing to a crawl and then dropping. After several calls I was told I needed a new Modem... which came today. After setting up Modem the problem persisted. I'm a patient woman, but this is beyond frustrating. Several calls and duplicate walk throughs and we still could not find the issue. I asked for the issue to be escalated and was told there was nothing they could do. I asked about how to find out when my contracts were up so that I can find reliable service and was transfered to billing... and disconnected. I've tried everything and nothing works. Paying for a new modem I didn't need was frustrating enough. Add to it that when I finally demanded to have the ticket esecalated I got a supervisor who's response was to send me to billing to be done with it. I'm not sure where to go from here. If they can't help me since its wifi, is there someone I can speak to about contract due dates so that I can move to a company where I can access my wifi? In case there's support to reach out to... 1. Wired works fine.2. Wireless will start to slow as if there's a large file downloading, then drop completeely.3. New modem, reset old and new and changed wires.4. Cleared network chatter.5. Modem three feet away, no walls or obstructions.6. No changes to modem, laptop, cell phone, or tablet.

Help with timecode and video freeze during Print to Video

This has happened twice in last couple months. Timeline is usually around 22 - 23 minutes. At some point during playback to HDV deck using Print to Video via FireWire, the timecode freezes and so does the video for approx. 2-3 seconds, then resumes on 2-3 seconds later in the timeline. Everything is still in perfect sync. Playing back the timeline on computer reveals nothing. Please, does anyone have any suggestions at all??

You should be mixing down the audio before you record to tape, try that if you haven't done it first...
If that fails, export a self contained QuickTime movie, then see if it doesn't print to video or edit to tape better.
Use the fastest drive you have for the QT movie's playback, and it should be something other than your startup disk.

Skype calls keep dropping and Skype freezes?

I have good internet and every **bleep** minute or so when im in a call with my friends, skype freezes (but not like "not responding", i can click buttons, they just don't do anything) and the call is dropped for like 40 seconds and then it fixes itself again. it does this very often and im getting tired of it.
i've re installed skype, re installed java, installed an older version of skype and NOTHING works!!!
It's not my internet because while skype is frozen, i can be playing a game flawlessly, or googling things, something is wrong with my skype.
also my computer is really good (custom built gaming pc)
Skype is really pissing me off!

Same sort of thing is happening to me and has been happening for a while, except that it doesn't come back in 40 seconds. It's so annoying, and I'm convinced that skype is the biggest and most worthless piece of **bleep** program out there, I can't wait until there's a viable alternative. It will just stop mid call, as if the other person isn't talking, then it will become unresponsive. It's not like it's unresponsive and greyed out with Windows saying it can fix it, it just completely ignores everything. If I want to end the call, too bad. If I want to force quit the app, too bad. If I want to sign back on, too bad (it's already running). I have to restart my computer so many times throughout the day that it interferes with my work and I depend on Skype to connect my coworkers. It's so full of issues that I'm fed up. No updates or downgrades help me either, I've tried almost every one of the "good" ones.
