• Keyboard problem Z70-80, please help

  I've had this laptop for months and it started just today. Basically, most of the keys work fine, but a few essential buttons are screwing. Just web browsing, for example space refreshes the current page and the right arrow key opens the search v + b, m and n will also tap the other pressed individually character (by pressing the results either v or b in "vb", even with m and n).

  I use this machine every day and really need the built-in keyboard to work properly, please help me out here .

  As you confirmed with two different operating systems. Its most likely material. I doubt a bios field that would affect it and it might migrate to external keyboard as well.

  Hi rabinp

  You must change the permissions for the folder Adobe.

  Please see the discussions below to fix it.

  Update on CC (for PS, LR and bridge) online and met a permissions problem with LR on three files?

• I have adobe first 10 items and I'm having some problems with it please help

  Here are the problems I am having with Adobe Premiere Elements 10:

  1 transitions won't load. The word loading will appear and it will not come to the top.

  2. the videos will not play smoothly. When I press on play skipps in a way he will not play smooth, making it very difficult to change.

  3 keeps closing on me. It will be something that comes up that says "Adobe premiere elements has stopped working and closes in the program. He does constantly.

  Please help me I don't know what's the problem with him.

  The first two numbers sound like a video driver issue.

  What is the make and model of your video/chip card?

  What is the installed video driver number and date?

  For the last number, it could be many things, including the video driver. I look over this ARTICLEand if there is nothing in the first part, then proceed to set up a computer in the second part of the OS. It would probably be a good time to publish the complete specifications. your computer and the images of your project and Source. Finally, the third part covers many of the troubleshooting tips and provides many links.

  Good luck

  André,

  Thanks for your reply, but I think that I have fixed my problem.  When I built the system, I never could the 2nd strip of memory to work.  It would not just start my system at all.  I thought all along that I had a problem of memory based on my last sentence.  I finally went out and bought another brand memory and did not have a BSOD on the last 2 days.

• Windows 7 download bandwidth is strangely throttled, please help.

  Hi all

  Thanks for reading this.

  Here's my problem. I have my desktop PC running windows 7 Professional 64-bit (authenticated copy) connected wireless to a router connected to a modem cable (Time Warner Cable). I'm supposed to receive 40mbps 5 Mbps upload speed and download speed. This is where it gets strange. My home PC download gets only 2 Mbps but my upload is getting 5 Mbps. I thought it was very strange.

  Here's what I did:

  -J' I brought my laptop to friend, and his link windows professional wireless 7 to 40mbps on my router connection / Wireless even (which suggests that this is my desktop PC which is the problem)

  -My ipad and android phone on speedtests also get 30-40mbps when it is connected to the wireless router

  -J' got a new card wireless (thinking it was the USB dongle) and he's still only 2 Mbps (this is a link Wireless N PCI express - TP-4800)

  -J' tried a connection to the local network through my on-board GB ethernet to the router, still 2 MB/s download, 5mbps download

  -J' have switched Internet Options-> connections-> Lan Settings-> automatically detect the settings off (someone else said that fixed their problem) box

  -J' disabled carbonite, audio, anti-virus (sophos) and many other non-essential services in the services section of the Manager of tasks without result.

  -J' started in the safe mode and still download 2mbps

  -J' tried to add the following registry key based on someone of another experience DWORD32 HKEY_LOCAL_MACHINE->SYSTEM->CurrentControlSet->services->LanmanWorkstation->Parameters->DisableBandwidthThrottling 1

  -Download less than downloading is very suggestive that something is limiting the bandwidth to download on my PC only... I can't understand what he...

  My desktop PC is an AMD A10 7850 k kaveri CPU with the gigabyte card mother/AMD chipset drivers last A88x - D3h Council, and I tried several wireless and wired adapters and for some reason, it's just this PC. I have sophos AV installed and he was not accused of any threat to this system, nor I web practices to high risk.

  Any help on this would be greatly appreciated! Thank you

  OK... so I think I solved the problem.

  Here's how. I have Accelerator disabled random networks AppEx and wam! immediately improved bandwidth. In fact, I can check the box on and it slows down, uncheck the box and immediately my changes 1-2mbps to 50mbps. No other changes have been made except this one.

  It's crazy. It is supposed to speed things up, but it does the opposite. Mabye it's just with my material, but if it can help someone else, I'll be happy.

• In Windows Vista, I can not change the settings in my 'reports on problems and Solutions' Please help

  I'm the administrator of this PC, and it is the only account that I have.

  Quick fix pls help thnks

  Hello
  • What happens when you try to change the settings?
  • You receive an error message?
  • What were the changes made before the problem occurred?
  • Which settings you want to change?
  
  You can view these methods:
  Method 1:
  I suggest you to disable any program of security on your computer and check if it solves the problem.

  After reviewing the question you must reactivate the security on your computer program.

  Note: Run the computer without antivirus software or firewall is a potential threat to the computer; Be sure to activate security software after completing the troubleshooting steps and after identifying the problem.

  Method 2:
  I recommend you perform the clean boot.

  Configuration of your system in a clean boot state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.

  See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

  How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
  http://support.Microsoft.com/kb/929135

  Note: After troubleshooting, be sure to set the computer to start as usual as mentioned in step 7 in the above article.

  Hi Vivremm,

  1. what happens when you try to change the date and time are you get any message of error?

  2. what exactly is the problem we are facing with Windows?

  No update of Windows, to keep your PC safe and running smoothly.

  There are different types of updates. Critical updates or security updates protect against malware and security exploits vulnerabilities. More updates, correct the errors that are not related to security, or enhance the functionality.

  Each time a new update is essential to avoid a newly discovered operation or prevalent targeting Windows users. Windows Update can be configured to install updates automatically as long as the computer is connected to the Internet

  I recommend you to check the date and time, see the procedure in the following article.

  Change the display of dates, times, currencies, and measures

• Virtual disk strange behaviour - please help

  Hi all

  I wonder if anyone can help. I started to experience a strange problem on one of my VM today.  I have a virtual machine running freenas.  The storage drives the actions of free storage to sit on are physical disks connected directly to the virtual machine and run normally, because of the way the works of freenas real HDD can be small enough and for the virtual machine, it's a prealloue virtual disk is 16 GB in size.  It is the only virtual machine sitting on a physical hard drive 256 GB. Today, I noticed a problem that the file for the virtual machine has become 240 GB in size, is probably not a normal behavior for a 16 GB VM.

  I checked snapshots which he had two auto protect snapshots which I deleted and disabled auto protect. This was reported to the size of the folder up to 182 GB.

  On the use of exploerer to view the folder it seems to be a large number of files, as shown below. Can someone explain if it should be there?  Also, how else remove them safely.

  Thanks in advance

  Thanks for the offer, but after a lot of interference and a virtual machine rebuild I managed to solve the problem.

  The solution was to set the 2 drives physical independent mode with persistent active. for some reason unknown to me this seems to prevent the creation of multiple disk files, it seems workstation creates them even when there are no snapshots.

  Time will tell us but seems to have solved the problems. Fingers crossed

  Thanks for all the help guys.

  Dear friend,

  Why do you think you have problems with shared pool? In the ASH report you are provided, there was just 2.5 medium active sessions and 170 requests during this period, he is very low with swimming pool shared, problems
  you have some queries that use literals, it will be better to replace literals with bind variable if possible, or you can set the init cursor_sharing parameter to force or similar, this is the dynamic parameter.
  But it is not so dramatic problem in your case!

  From ASHES of your report, we can see that top wait events is "CPU + wait for CPU", "RMAN backup & recovery i/o" and "log file sync" and 65% of your database of waiting time. And even in the background waiting events.
  If I understand well report, you have two members in your redo log groups, you have problems with log IO writer speed, check the distribution of files on the disc, newspaper editor is slow causing it to wait for the other sessions. High
  processor can be related to rman compression. Best service can we sea GATHER_STATS_JOB consumes 16% of activity 33% consumes rman and only 21% your applications and also there is something running
  SQL * more under the sys (?) account. There is from the top of the sql page, this is the sql in your application, if I understand correctly, 'scattered db reading file' event indicates that full scans have a place, is it normal that your application? If Yes, then try using
  running in parallel, as we can see in the section "Sessions running PQs Top" your report there is no running in parallel, but as I understand it there are 8 processors, try to use parallel executions or avoid full scans. But consider that
  When you do full scans in parallel PGA memory not used CMS, then decrees setting pga_aggregate_target SGA and increase respectively.

  Is there another application or a program running on the server except oracle?
  Is the performance degradation was strong, I mean yesterday, everything was ok, but today all the evil, or it was good?

  Check the reasons for the slow newspaper writer, it can greatly affect performance.
  Also of 90% of the performance problems generally because of the poor sql, poor execution plans.
  Also if you use automatic memory management, tap Settings, but you must know that in this case the settings will identify the minimum values, this is why define them to lower values in oracle can manage
  entirely.
  Don't increase your SGA at this stage, get the awr report, use @$ORACLE_HOME/rdbms/admin/awrrpt.sql, check your cover shot.

  BUT first, you must change your backup strategy, look at my first post, after that check performance again, before you do that it will be very difficult to help you.

  Good luck
