• Satellite M40-110: WLan is not working properly after sleep mode

  Hello, I have a M40-110. I have some problems with my wireless adapter. After I closed the screen (bed) and the computer goes into sleep mode, I open the computer screen becomes active, but this time the wireless adapter is not working properly and I can't connect to Internet with my wireless adapter. Sometimes, it seems that the wireless adapter has established a connection, but I can't send and receive data from the Internet. Sometimes after this case, the wireless adapter becomes invalid.

  My Service offered to enable the bios wake-up-on-lan option. After doing this, the Internet worked properly.
  But I am wary about this option:

  (1) not allowing this option cause draining my battery quickly?
  (2) this option doesn't make that hides my hardware failure (wireless card) and it is really necessary to solve this problem?

  Thank you

• Windows 7 "no DNS (or no network) after sleep (wake up) sleep (or Hibernate).

  The purpose of this thread is to understand the expected behavior of the TCP in Windows 7 stack and the cards on the resume from sleep/hibernate - not - display the suggestions that have been posted in other threads.  I also wanted to gather some folklore on this subject in one place...

  It seems to be a group of people having this problem Windows 7 "no DNS (or no network) after sleep (wake up) sleep (or Hibernate)" without definitive duty (or with various) responds to what the issue is.

  Do some reading on this in various places, I see:

  -Suggestions to disable UPnP.  This should be largely irrelevant to the problem.

  -Reset the default router.  Generally, this should not be necessary.

  -Reinstall Windows 7 (ah yes, the panacea for all ills!).

  -Replace DHCP static IP address.  This should not be necessary (considered at best as a workaround).

  -If it solves the problem, it points the finger at DHCP feature / state on the curriculum vitae of sleep?

  -Disable the firewall.  This shouldn't be a problem (why would it).

  -If it is a question, it is likely to be isolated, rather than the majority of the cases.

  -VMWare (or similar) virtual networks.

  -This could be a problem for some people.  It would be useful for anyone who has a problem to confirm if they have VMWare or similar virtualization installed products (who can create virtual networks).

  -Disable the TCP (TCP sliding windows) tuning car.

  -It is possible that TCP auto tuning could be a problem for some people - but - unlikely, it would be a problem for people only on the recovery from sleep mode.  I think that anyone with questions about the TCP (TCP sliding windows) tuning car rather than questions on RESUME intermittent connectivity problems.

  -Some people report improved performance when turn it off this feature.   Report MSFT from 10 x to x 1000 in laboratory performance. conditions.  It's one you need to test yourself to see if it helps or otherwise.

  -NETSH INTERFACT TCP SET GLOBAL AUTOTUNING = OFF

  -NETSH INTERFACT TCP SET GLOBAL AUTOTUNING = NORMAL

  -It works on XP but not on Windows 7?

  -It is fairly widely commented that the TCP stack has been re-written/improved thanks to Vista and Windows 7.  It is not surprising, therefore that problems on Windows 7 that do not exist on Windows XP.  This does not necessarily imply that the Windows 7 stck is bug, just as not all software and peripheral food chain TCP are speaking the language of same/current (in the absence of a better technical description).

  -One wonders, therefore, are only optimizations issues additional tuning and unloading that have been made in the new stack TCP?   How this confrontation with the problems that occur only in the curriculum vitae of sleep/wake extended?

  -Some people recommended prevents the system from voltage of their cards during the standby/hibernation.  Does this means:

  -The card is not dynamic.

  -If the card is allowed to be turned off so there will be a lag between the state saved in Windows and the State represented (none) in the card when the system is out of his sleep (or Hibernate).

  -Perhaps, it's something that needs to be addressed in the functions of battery/sleep TCP in Windows 7 - How to handle/recover the situation when the NETWORK adapter is turned off?

  -If we put the system to sleep, we want to have power supplied to the maps or not (what are the implications)?

  -People have the same problem for the hibernation?

  -If there is a problem of State related to the cards, would be - why, in some cases of people solve the problem by disabling optimizations that involve some treatment being given cards instead of being carried out using the processors.  If it was kept in the processors, we have consistent state on the resume (as opposed to cards)?

  I think what I understand of MSFT is here:

  -What is the behavior designed in the stack revised to ensure a consistent state between the adapter, battery, previously obtained DNS, DHCP settings, etc., the curriculum vitae of sleep/wake extended.

  -Unlikely connections persist across sleep/hibernation - so are they remind/re-restored?

  -Windows 7 has more work to properly manage this for cards that - are - power off during sleep?

  -Is - it a requirement of MSFT at this time for an own CV, the card must stay lit?

  An exchange of views on how this is supposed to work for MSFT would be useful.  Then perhaps hundreds if not thousands of people facing this issue can understand why it happens and how they can solve.

  Thank you for spending time and energy on it. I had a frustrating to deal with this problem, but - finally, disable virtual network cards seems to have helped.

  My sound card has been disabled when I install an automatic update for windows. There was an extra audio driver in Device Manager 'bluetooth AV audio' and audio peripheral anoither like this.

• Plugins does not work in After Effects CC15.3

  Everything worked perfectly yesterday. A project of client using some of my favorite plugins like Trapcode Form and particular.

  After update today, would continue my project where I left.

  However, the majority of my plugins disappeared, leaving me unable to progress, short on time.

  I had to completely start over, with a new idea and the standard after effects plugins.

  I tried to reinstall them, but they may not appear.

  Did anyone facing this problem too?

  Can you please help.

  Like HippieBoy, but on Windows 10, I tried to copy the plugins trapcode manually from the

  "C:\Program Files\Adobe\Adobe after effects CC 2015\Support Files\Plug-ins\Trapcode.

  TO

  "C:\Program Files\Adobe\Adobe after effects CC 2015.3\Support Files\Plug-ins\Trapcode."

  and my trapcode plugins where backward. The amazing thing is that I have installed the Plugin Trapcode after having updated to 2015.3 CC. The reason was probably that the Trapcode plugins trial version installed to AE CC 2015 and that the folder was still here the licensed version of Trapcode installed in the old folder.

  I am so angry with my computer because I paid 1.5 k for a computer that is not able to make the task easier for a modern computer. Even a €50 computer has embedded software that can handle a resume from sleep without having to restart the entire software... Imagine if you had to do it on your iPhone, you will eventually get a refund within a week or less because it is not normal in 2015 to have this kind of problem. I hope that I have no problem with safari on my 6s and I don't plan to spend my browser because Safari is part of the Apple ecosystem and have the perfect sync and battery management.

  So I need to get this fixed a problem and I really need your help because a lot of people had this problem on the internet, but NEVER seen someone who explained how it happened is the correction of a problem. My Mac running the latest version of the software which is 11.2 starting today.

• Browser blackBerry Smartphones not working anymore after 2 years

  Hello

  I hope someone can help me with the following: after 2 years my internet browser no longer works on my BB curve 9300 (not via 3G, no WiFi). FB and Whatsapp still work.

  Now my smartphone is only half of a smartphone, so I hope that your team of professionals will be albe to help me in no time.

  Thanks a lot from the outset.

  From what you describe, I can only deduct that the Service books never happened to your BB... and if you waited the hour and then restarted. And even then your services were not working.

  Given this scenario, you next fall at what stage followed 3 in what I provided above... in touch with your mobile provider for formal support. Something went wrong turned into the connection between your device and your network of carriers... only they can watch their network to understand why this has happened and remedy.

  It is true that, in many markets service BB/BIS costs indeed data plans more 'generic'... it's because there's infrastructure that the carriers and the BB must provide/support so that the exclusive services of BB to function. Non - BB devices don't use this infrastructure, and so in many markets the carriers can get away with paying more for it. But this price is set by carriers (not all markets have a surcharge for BB services... services of BB to sell at the same price as non - BB... it varies).

  Good luck!

• programs do not work immediately after that fix malware 'trouble Shooting permit' said "applied settings are windows xp - but I have windows 7 ultimate

  computer doesn't have any malware left in it. but subsequently noticed that things do not work right - google earth is good example. I then right click on the icon and place comes the list such as 'open with' but there is also one "Troubleshoot for compatibility" list just then up to 2 choices - one of the top is "compatibility with the applied settings" but it says "windows xp - service pack 2" it lists not windows 7 or windows 7 ultimate. " so I clicked on troubleshoot and place comes the yellow triangle exclamation "problems found - this program is not compatible with windows xp in terms of statistics... '.  I then started right click on other programs such as photoshop - real player - makes no difference they say ALL not compatible with windows xp.  --> the next part is probably not bound--> I have 2 computers connected to the same monitor - but they are not connected to each other.  that has windows xp.  during the correction of malware the second computer was not on at all.  during the correction of many programs scanning is headed by correspondent to customer of malwarebytes.  many things have been updated such as the intnernet Explorer and the latest updates of windows of all kinds.   is it possible that somewhere in the registry that something is stuck in there, making the computer thinks that it has installed xp?  for the 'settings applied' - it's just a matter of finding where this setting is and he said somehow 'windows 7 ultimate - windows xp no' while the programs will run to the right and things normally appear on the screen?  Another example is happening on the line using the Explorer - screen pages but look outdated with problems strange such as buttons are invisible - or images have large white rectangles in them.  computer starts slowly and "locks" a lot.  my main computer is very fast - all ratings on the performance page are high – most are 7.9.  somewhere in there, the computer has a confilict THOUGHT for PROGRAMS HE has Windows XP.

  The second computer, I even unplugged all caps - nothing is hung even to monitor but the problem persists.  CLICKS TO APPLY WINDOWS SETTINGS 7 - INSTEAD OF XP - OR IS IT A DISASTER WHERE I HAVE THE GEEK SQUAD TO COME IN?   Thank you

  Even now, I noticed that when I am ready to post the question - computer automatically knew that I have windows 7 - Internet explorer 9.  so computer works but on SOME things - he apparently thinks I have xp.   is it possible that ALL the people that right click and check compatibility, it says 'windows xp' without concern if they windows 7 or not?  have been emailing friends with windows 7 for you, please try and answer - but nobody will answer...

• Thunderbird does not work properly after copying old content profile in the new profile, what can I do

  My old laptop crashed, but fortunately I got the hard drive out, who now works as an external drive. I installed TB on my new laptop computer. I copied the contents of the old file to profile in the new profile file and start of TB. I have all my files of pace, but TB does nog works correctly. After that connection, it takes forever to load the new messages, when I leave a message to another, the first answer I get is "TB not responding' and after a few minutes, I finally get to the next message. Same story with 'reply' or 'delete '. I already tried to delete the index file and have tuberculosis still indexing message folders, but this did not help.

  I noticed that my old profile files seems to have a sort of double files in the subfolder Mail, old accounts. For example: pop.tele2.nl, pop.tele2 - 1.nl, pop.tele2 - 2.nl. I'm not sure what they are (they seem to hold different versions?) or is it relevant?

  When I search the AppData/Roaming/profiles I'll find it (on the old and the new hard disk as well) but I can not navigate on him (some parents of hidden file)? I checked the rights on the files of my account profile (Administrator rights). I don't know what to do more, so I hope to help.

  Re: for example: pop.tele2.nl, pop.tele2 - 1.nl, pop.tele2 - 2.nl.
  Here's the e-mail accounts for pop e-mail account. If you have several addresses on the same server, it will have the same name but an additional example:-1 appended to the name. If you got an e-mail account, it can also create and add the additional number. Why you have several, I can't say with certainty what caused them without knowing what you have done. The point being, you must have the directory Local pointing to one that is correct and has all your existing emails.

  Profile files are hidden files.

  It will say something like this:
  C:\Users\User account name\AppData\Roaming\Thunderbird\Profiles\abc12345.default\Mail\pop.tele2.nl

  Copy paste the info on this issue, so I don't know which e-mail account you use.

  How many email accounts you listed in the left pane in the account settings? You have just the one pop email account and local folders?

  What antivirus do you use?

  How many emails you have in the Inbox folder?
  It is advisable to use the Inbox folder as a mailbox for incoming mail, and not as a general storage. Suggest you create folders and move all the emails in the Inbox in other appropriate folders, then right-click on Inbox and select "Compact".
