Bad connectivity with T510 minidock

I've actually been using the dock for quite awhile now; normally it works great, and I have my external monitor attached (1920 x 1080 @ 60 Hz, 2 ms response) and it all works great. There's just one problem though -- my USB connectivity seems to be poor. If I push down on the laptop keyboard (where the dock connector joins the laptop) I seem to get the "USB device not recognized" issue, and after this the only thing I can do is restart my computer to regain connectivity.
Does anyone else have issues like this, and if yes, has anyone found a solution to it?

Yes it's a known issue for us as well as a number of others:
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T410-docking-station-issue-VGA-external-mon...
20 - 30 systemboard replacements later, Lenovo has still yet to come out and say: "Yes we recognize the problem"
Call Lenovo and push them for a motherboard replacement. We swapped out a number of docks before we found that replacing the motherboard does the trick.
Good luck!

  • Bad connection with Facetime

    Hi everyone,
    So since I've updated to OS x Yosemite, my Facetime will jump to 'bad connection' after several minutes. I know that there's nothing wrong with the internet, because it works fine and I've changed and checked it different times.
    Does someone has this problem too?

    Ok, I have tested it with a Free SIM card.
    The result of the test is:
    -Facetime works with occasional time-outs when using a Free SIM card over 3G.
    -Facetime does NOT work at all ("poor connection") when using an Orange SIM over 4G.
    As Facetime was working without any problems over Orange 4G until last Christmas, and it has never worked since,  this looks very much like an Orange netwqork problem.

  • Bad connection with MP54G2

    Hello,
    I've got a MP54G2 WLAN-Card in my notebook.
    I use my notebook for VoIP and have a big problem with my WLAN-connection: Every few minutes the connection fails for a few seconds (but it doesn't disconnect). It seems like that there is no data transfered in this time and so I have a gap in my phone-call.
    When I put an PCMCIA-WLAN-Card in my Notebook, everything works fine for me. How can I solve my problem?
    Thanks

    It's a driver problem -> for more information take a look at http://61.222.76.235/phpbb2/viewtopic.php?t=363

  • Bad Connection with Airport & PC Laptop

    I'm having a problem here. I have an old iMac. I bought it in 2000. It's one of the Special Edition Graphite models. I just got an (original) Airport card for it to try to make a wireless network so that I could connect using my work laptop (IBM Thinkpad). Since it's my work computer, I don't want to try to mess with settings on that computer (and I'm not sure I could anyway).
    I really don't have much knowledge about this, so I'm just going to explain what I've done and what happened, and hopefully someone who knows more about this can figure out where I've gone wrong.
    I installed the card, and then I have the Airport Icon up in the upper right corner next to the time. So I go in there and select Create Network. I name it and leave the channel on Automatic (11). Then I hit Show Options and check the box for Enable Encryption. I selected 128-bit and entered a 13 digit password made up of letters and numbers. (I also tried 40-bit with a 5 letter password.) Then I hit Ok.
    Going into Internet Connect, it shows the network with a good signal level. When I look at Wireless networks on my PC, it lists it, although the icon next to it is two computers (for computer-to-computer) rather than an antenna-like icon that the other networks showing up have. I connect to it and it says that I have excellent signal strength. But when I try to go to a web page, I get nothing. hen I look at the status for the connection in the PC, it shows a lot of Packets sent, but none received. And Address Type is Automatic Private Address, while IP Address is 169.XXX.X.XXX. Subnet Mask is 255.255.0.0. There is nothing for Default Gateway, DNS Server, or WINS Server.
    Can someone help me figure out how to fix this and connect properly? I would really appreciate it! If you need any more information, just ask.
    Thanks!

    That is the solution.
    It is not possible for a Windows PC to connect to an encrypted software base station (a Mac sharing its internet connection via Airport).

  • Bad connection with my airport-express

    I have all my music in the cloud and when I play it from my computer via the airport-express it works perfect. Now I bought an i-pad and when I play music from the i-pad via the airport express it is contently interrupted. It is not the wifi because when I use the i-pad as speaker it works o.k. Any ideas?

  • Thunderbolt to FireWire adaptor/Bad connection?

    Has anybody had the same matter as I have? Please let me know!
    'Thunderbolt to FireWire Adaptor' I bought doesn't properly fit in the Thunderbolt socket of my Macbook Air (that Thunder mark on it).
    It does a half of it and doesn't go deeper. I'm sure any info of photos and videos I saw online that people uploaded look it fits in all, but mine doesn't.
    Is this normal? One I found on Apple Support Community says
    'Be wary of the bad connection with the adaptor though, it falls out with the slightest movement.'
    It sounds like talking what the same I have. If it's so, I can use it even it properly not goes in? or I can claim the tech support?
    If anybody knows info, please let me know! Will appreciate it. Thank you!!

    Yikes, that's sad to hear.
    I can't test it, no TB here, but are all these drives self AC powered, ie. no bus powered drives?

  • Bad connection using facetime with ios 7

    when i use facetime its really bad connection keeps feezing since updating to ios 7 on my ipad mini was never like this before i have fibre broadband so its not my internet as that is super fast i have also noticed that the new update is very slow and sluggish when using certain features has anyone else experienced this

    I know you can't restore a backup with ios7 and Find My Ipad turned on. I would first set it to Never update device, an don't restore backup and see if that will allow you apply the profile. If that doesn't work. I'd do a complete wipe of the device, prepare it again and then try to install the profile.

  • E8350 - bad upstream performance when LAN clients connect with 1000mb/s

    Our office LAN is all 100/1000mbs capable. Our internet provider is 100 mb/s symmetric internet. We believe we've found an issue with upstream buffering in the E8350. 
    A) A laptop connecting at 100mb/s directly to the E8350 is able to upload at 80 megabits/s
    B) The same laptop, connecting via 1000bt directly to the E8350 only gets 10 megabits/s or so
    C) Other laptops connected through our LAN at 1000bt also suffer poor performance
    D) Putting an older switch which is only capable of 100mb/s between our 1000bt LAN and the E8350 throttles correctly, and we can obtain higher upload speeds for the entire network.
    We suspect that in situations A & C,  the E8350 is not throttling/buffering traffic arriving on the 1000bt connection correctly, causing the poor upload speeds.
    Firmware version is 1.0.0

    1000bt? what is that? Do you mean 1000Mb? or 1Gb? 
    Preferred connections with this router is the use of 1000Mb or 1Gb adapters and switches and CAT6 LAN cabling for wired LAN conections. 100Mb could slow down some performance and you'll not be able to use the 1Gb connection pipe. 
    Is these connections on the wired LAN cables? 
    Ensure all devices with wired LAN connectons support 1000Mb or 1Gb speeds. 
    Ensure all devices with LAN adapter cards are updated for dirvers.

  • I can no longer log into my ichat linked to my gmail.  right after opening up ichat, receive the following message:  lost connection with jabber.  the server has unexpectedly disconnected.

    i can no longer log into my ichat linked to my gmail.  right after opening up ichat, receive the following message:  lost connection with jabber.  the server has unexpectedly disconnected.  how to troubleshoot?  thanks.

    Hi,
    There can be many reasons why the Login is "up the creek".
    Any break in the network at your end whilst logged in will cause  an issue.
    A sort of discrepancy between what iChat thinks the state should be and what the server thinks.
    If they don't agree the server will refuse to accept.
    A Crash at the server end which does not log you out properly will also do it.
    Any file at any time can be come corrupted.
    Luckily with the iChat .plists they are recreated if removed with an iChat Restart.
    If it were AIM you can also get your Account Suspended  and this will not log you in.
    (It tends to happen from Chat rooms where people notify AIM about bad behaviour (as they see it) and you have to apply to get Un-suspended).
    Most of the big IM services use multiple servers.
    Sometimes these go out of Sync.
    In the case of AIM this happens when they remove Old unused Screen Names from people's Buddy List prior to making them available for re-registration.  I am not sure if this happens at Google.
    You seem to be talking about an account that has worked at Work and having new computer at home.
    As I mentioned the Priority thing you have not said that it has coincided with the new computer logging in  (this will kick the work Computer out of Google whether you are logged in  on the Web Mail page or in iChat)
    IN addition to that iChat stays partially logged in for Off Line IMs
    This is done in the background by a support app called iChatAgent
    If your Computer is ON but ichat is not started people can still send you Messages.
    Instead of saving these on the server until you login iChat will start up.
    Depending if the home Mac is effecting the Work Login it may be holding sway over your Login.
    Using your girlfriend's login may have booted her Off Line where she normally uses the name/login.
    The AIM Side can be specifically set to allow Multiple Logins and therefore NOT allow them.  If this happens you get a warning and messages to do something about it.
    You do not get these in any Jabber or Google Login as the Priority setting is supposed to take care of it.
    If the Login works at the Web Mail Login and on one computer then the .plist on the work computer is the most likely issue.
    There is a small chance that a Corrupt Buddy Pic (Home Folder/Library/Caches/com.apple.iChat/Pictures) may be the cause.
    Set this folder to icon view and also use the Finder's View Menu > Show View Options and select icon view.
    This should show all pics as their icon.
    Check that all display properly.
    At this point I would try a COMBO version update install of the last Update you did over what you have.
    This often corrects hard to trace things

  • How to connect with sony bravia.

    Hi,
    I'm trying to connect my Mac pro with my Sony Bravia LCD TV. I bought a MiniDP to VGA cable and I already had a VGA extension to connect with my TV. I used to use that cable to connect my other laptop and worked ok with frequent "no synchronisation". Once I connected all, nothing happened. I restarted the PC but nothing happened. I tried to play around with all connection, but nothing happened. I do use windows XP in my mac pro as well and it didnt work their either although my other PC working fine with same VGA cable. I'm not very sure my MiniDP to VGA cable is working or not? Is there anyway I can check its working. Also, someone (sorry forgot the name) in the forum said, HDMI works better then VGA. What do I have to do to connect my PC through HDMI. Is there any direct cable to connect MiniDP and HDMI? Thanks for your help.

    The best way to test if the VGA adapter is bad or not is to try it with another display, preferably a computer monitor instead of a TV. If it doesn't work with a monitor, then that's stronger evidence the adapter is bad.
    There are MiniDP to HDMI adapters. Here's an example of one. I believe this company will ship internationally. You might be able to find UK sources for similar adapters.

  • I got a new modem and imac says connected with the airport, but cant get a web page to come up on either safari or firefox

    I started having internet problems with all my devices in the house, ipod, imac, pc laptop, tablets, etc... found out after being on the phone with comcast for hours, they determined my modem that they supply was bad. So I have the new modem now and very simple to install it and get everything working. However, I cannot get online with a web browser of any sort on my imac. which had no issues before.
    All my devices in the house work perfectly now with the new modem and my speeds are great, and even the imac (with the airporter) states it is connected. but I cant do anything pertaining to the internet. I have spent hours on the tech line with comcast and they cant seem to find the issue and said it is with my Imac, even though it was working fine before.
    Does anyone have any ideas, is there simply something I'm missing, please help. As I stated before, everything else that we own works great and has great connection. and the Imac states it is connected, but mail, internet, non of that works...??????

  • Safari cannot create secure connection with certain websites

    I have OS X 10.10 with every available updates, and Safari's currently unable to 'establish secure connection' with some site I'm trying to connect, most disturbing being the whole Steam network (store/support.steampowered.com, steamcommunity.com, etc). IE (via Bootcamp), Chrome (both standalone and integrated into Steam client) and Firefox have no problem doing so.
    Considering sometime before the in Steam browser indicated the site as insecure (a red lock icon with a cross, typically used to indicate bad cert) for a short time, and hearing of certs issued to gov agencies for man in the middle, I compared the cert for store.steampowered.com/login (which, in contrary to most content on that domain, forces a secure connection) and this discussions.apple.com. Well Firefox and IE do show a normal grey lock icon without organization name, and Chrome admits the website's ownership is unverified (in details, it says ownership is verified by the CA but there's no public verification record; the secure setting of that site has outdated, too) despite having Valve's name and green lock icon. So the cert could be a fake since it's an ordinary (I guess?) cert from a EV authority (DigiCert High Assurance EV CA-1 in this case). The certificate shown from Chrome is totally fine (not a single red cross in the chain), though.
    Well there're other https resources Safari fails to create a secure connection with every now and then. I just forgot/ am unable to test them with other browsers (Sometimes it's not the page itself that can't be retrieved via https, but some resource it loads. Sadly I only know how to use Inspector in Safari, though I'm sure other browsers have similar functions, too). I suspect Safari just refuses such certificates (or the AES_128_CBC method maybe) while other browsers accept it. Is there an override for this?
    Weird enough, https://ev-root.digicert.com/ has grey lock on Firefox and Safari. Seems overriding is the only workaround.
    As a side note, my Safari freezes upon loading PayPal, being ir-responsive for tens of seconds on every activity such as clicking a link. For most of duration of the freeze no high CPU usage is monitored, though ocspd does sometimes take 50% or so, and the web process bursts into 100% immediately before unfreezing. Guess Yosemite has some issues with TLS on the system level.

    This could be a complicated problem to solve, as there are several possible causes for it.
    Back up all data, then take each of the following steps that you haven't already taken. Stop when the problem is resolved.
    Step 1
    From the menu bar, select
               ▹ System Preferences... ▹ Date & Time
    Select the Time Zone tab in the preference pane that opens and check that the time zone matches your location. Then select the Date & Time tab. Check that the data and time shown (including the year) are correct, and correct them if not.
    Check the box marked 
              Set date and time automatically
    if it's not already checked, and select one of the Apple time servers from the menu next to it.
    Step 2
    Triple-click anywhere in the line below on this page to select it:
    /System/Library/Keychains/SystemCACertificates.keychain
    Right-click or control-click the highlighted line and select
              Services ▹ Show Info
    from the contextual menu.* An Info dialog should open. The dialog should show "You can only read" in the Sharing & Permissions section.
    Repeat with this line:
    /System/Library/Keychains/SystemRootCertificates.keychain
    If instead of the Info dialog, you get a message that either file can't be found, reinstall OS X.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it by pressing command-V. Select the line you just pasted and continue as above.
    Step 3
    Launch the Keychain Access application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
    In the upper left corner of the window, you should see a list headed Keychains. If not, click the button in the lower left corner that looks like a triangle inside a square.
    In the Keychains list, there should be items named System and System Roots. If not, select
              File ▹ Add Keychain
    from the menu bar and add the following items:
    /Library/Keychains/System.keychain
    /System/Library/Keychains/SystemRootCertificates.keychain
    Open the View menu in the menu bar. If one of the items in the menu is
              Show Expired Certificates
    select it. Otherwise it will show
              Hide Expired Certificates
    which is what you want.
    From the Category list in the lower left corner of the window, select Certificates. Look carefully at the list of certificates in the right side of the window. If any of them has a blue-and-white plus sign or a red "X" in the icon, double-click it. An inspection window will open. Click the disclosure triangle labeled Trust to disclose the trust settings for the certificate. From the menu labeled
              Secure Sockets Layer (SSL)
    select
              no value specified
    Close the inspection window. You'll be prompted for your administrator password to update the settings.
    Now open the same inspection window again, and select
              When using this certificate: Use System Defaults
    Save the change in the same way as before.
    Revert all the certificates with non-default trust settings. Never again change any of those settings.
    Step 4
    Select My Certificates from the Category list. From the list of certificates shown, delete any that are marked with a red X as expired or invalid.
    Export all remaining certificates, delete them from the keychain, and reimport. For instructions, select
              Help ▹ Keychain Access Help
    from the menu bar and search for the term "export" in the help window. Export each certificate as an individual file; don't combine them into one big file.
    Step 5
    From the menu bar, select
              Keychain Access ▹ Preferences... ▹ Certificates
    There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to  CRL.
    Step 6
    Triple-click anywhere in the line of text below on this page to select it:
    /var/db/crls
    Copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    A folder named "crls" should open. Move all the files in that folder to the Trash. You’ll be prompted for your administrator login password.
    Restart the computer, empty the Trash, and test.
    Step 7
    Triple-click anywhere in the line below on this page to select it:
    open -e /etc/hosts
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. A TextEdit window should open. At the top of the window, you should see this:
    # Host Database
    # localhost is used to configure the loopback interface
    # when the system is booting.  Do not change this entry.
