• Equium A200-1V0: charger plugged freezes when starting laptop

  Hello
  My satellite developed a strange absence of the module.

  When the laptop is connected to the charger it does not start. LEDs light up, keyboard blinks once and the screen is bright, but it is completely empty (no Toshiba logo, no bios, nothing).

  There is however no problem when I start the system on battery (charger unplagged). If I plug the charger at any time during the startup of the system it freezes immediately. It does not strike, the mouse pointer does not move and the blue lights are solid. However the battery LED turns orange. I get the answer only to keep the power button down for 4 seconds - how well be able to disable.

  When I restart the laptop on the battery then only Vista starts without problems.

  Does anyone have an idea, what could cause this problem, switch power supply, motherboard, charger? Is there an easy fix for this?

  Could you please say how Toshiba deposit would charge to fix it?

  Thank you very much
  ARIC

  Hi arek_1,

  Are you using the original Toshiba AC/DC adapter or is it a 3rd party charger?
  Can you charge the battery while the laptop is turned off?

  It is certainly a hardware malfunction, but either it s caused by AC/DC adapter itself or mainboard (load control).

  I put t know how much it cost to fix this problem, but just ask an authorized service provider. Guys you can make an offer how much it cost, and they must determine the laptop before determining what part needs to be replaced. ;)

• PC freeze when starting games

  This is going to be a bit long, I hope that the details could shed some light on my problem. I have problems with the commissioning games. Whenever a game gets to a point where it begins to display 3d graphics, my system hangs. I have searched in many forums and found similar problems, but none of the fixes worked for me.

  First of all, I am under 4G of RAM, Intel Pentium D processor, as well to 3.00 GHz and a Nvidia GeForce 8800 GT.

  A little background first of all. I played World of Warcraft on my pc for a few years now. Back in August, I fell prey to a fairly widespread worldofraids.com keylogger that took advantage of a vulnerability in the Flash Player. My account has been compromised, but restored by Blizzard. I cleaned the files infected my computer off manually, as AVG did not catch them and installed Kaspersky, who caught a few others that I had missed.

  Over the next few months, I noticed decreases the performance of my pc. I would get about 35 fps in a fight against a boss, 15 3 next, after that, then on a picture by six seconds. Some of the members of my Guild suggested overheating, but another guildie told that my file has been flooded by debris from the keylogger. He gave me a list of programs to run (malwarebytes, smitfraudfix and ccleaner, among others). I followed his instructions, cleaned the infected nearly 200 registry keys and appeared for the raiding of next week without any problems (I even overcame damage for several fights counters).

  Our raid week finished, and in the meantime I played torchlight through steam upward all night before our next raid day. When I logged in the next night, my graphics glitched descent and I was unable to play. The screen would Pixelize, the sound would start stuttering, and I got a bsod. The bsod's happened twice and every other time the pc could just lock or to restart. I thought that this could be a problem with WoW, so I loaded with torches and got the same problem.

  My minidumps for the time, I actually got BSOD said being faulty nvidia drivers. I took my roommate's video card and put it in my pc and was able to connect to WoW without crashing, but my sound is released (Windows said it was due to an audio conflict). I put my card in the pc of a friend, and he ran wow without problem. I tried to update my drivers but also to roll back to the older drivers to no effect.

  I carried out stress tests on my system and the memory passes, my cpu goes, virtually everything up to the gpu, which still crashes my pc without indicating why exactly. The motherboard seems in good condition, with no bulge or leak capacitors.

  In my reading similar incidents, I thought that I might have some residual registry problems so I bought Windows 7 (as XP Media Center came pre-loaded on my pc) and a custom settled 64-bit, spares nothing. I downloaded the new drivers for everything and even updated the BIOS for my motherboard. I reinstalled WoW and it still crashes.
   
  By raising the specs on my card, I noticed that it requires a minimum 400W power supply. Mine was 300W, although she had worked for more than a year without problem. Might think that any change in my settings fan or similar
  be just enough power to defeat of drawing, I ordered a new power supply 550W. After replacing it, I fell again. I was able to connect only once for about 10 minutes after replacing the power supply, but the next time I tried to connect (several hours after turning off my pc) it crashes immediately.

  I did not get a bsod since the first couple of times, so I don't have the minidumps for access. I have disabled the automatic restart, but which causes just my system hang when I crash and I have to turn off manually.

  A couple of things more I noticed that may be linked: when I run WoW since the pitcher, usually the screen would go black temporarily and then proceed to the login screen. Since the problems started, in that brief moment where the screen goes black, it flashes a white text on the screen in a view type BACK. I was not able to read as it happens so fast, but he mentions shading and some other graphics settings. It's a short list of articles, about 10-15 lines.

  In addition, from time to time at my computer at idle (not in mode "standby", usually when I'm playing my 360) I hear the speakers make a pop sound, similar to when you turn on the. I checked what could be a short circuit by touching the case, but everything seems to be fine. Electrical installation in my apartment is a little older, but I use my pc, monitor and speakers through an inverter.

  I am quite at a loss what to do now, other than trying to replace my motherboard. If anyone has any suggestions, I'd be happy to try. Sorry it was a bit on the long side. Thanks in advance.

  Hi digimicah,

  Thank you for using Microsoft Windows forum.

  To troubleshoot BSOD, start your computer in Mode safe and check:
   
  Here's how:
   
  1. reboot your computer and start pressing F8 on your keyboard. On a computer that is configured to start to multiple operating systems, you can press the F8 key when the Boot Menu appears.
   
  2 select Safe Mode when the Windows Advanced Options menu is displayed and press ENTER
   
  If it works with Safe Mode, you can choose to run the clean boot.
   
  You can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  Note When you perform a clean boot, you may temporarily lose some functionality. When you start the computer as usual, the function returns. However, you may receive the error message, or you can experience the original behavior.
   
  Follow the steps below to put your computer in a clean boot state:
   
  Note If the computer is connected to a network, network policy settings may prevent you from following these steps. We recommend strongly that you do not use System Configuration utility to change startup options on the computer, unless a support engineer Microsoft directs you to do so. This can make the computer unusable.
   
  1. sign the computer by using an account with administrator rights.
   
  2. click on the Start button, type msconfig.exe in the start search box and press ENTER to start the System Configuration utility.
   
  If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
   
  3. on the general tab, click Selective startup, and then clear the check box load startup items. (The check box use the file Boot is not available.)
   
  4. on the Services tab, click to select the skin all the Microsoft services check box, and then click Disable all.
   
  Note Following this step lets services Microsoft continue to run. These services include networking, Plug-and-Play, record of events, error reporting, and other services. If you disable these services, you can permanently delete all restore points. Do not do this if you want to use to restore the system with the existing restore points.
   
  5. click OK and then click on restart.
   
  Check the link to learn more about the clean boot below:
  http://support.Microsoft.com/kb/929135
   
  When you are finished troubleshooting, follow these steps to reset the computer to start as usual:
   
  1. click the Start button, type msconfig.exe in the start search box and press ENTER.
  If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
   
  2. on the general tab, click the Normal startup option, and then click OK.
   
  3. When you are prompted to restart the computer, click on restart.
   
  Looks like there is a problem with the display drivers.
   
  As the posts above mention, the problem comes from your drivers.  BSOD crashes are usually caused by bad drivers (manufacturer's code).  With Windows 7 being again your manufacturer is not fully functional drivers.
  Unfortunately, when this is the case there is little Microsoft can do that the problem is with the provider code.  I suggest you knock it down on their support lines (send your incident information) and tell them that you found accidents as a result of their hardware and drivers - they should open the relevant support for you tickets.

  What you can try to:
   
  1. update all the drivers (sound card, graphics card, etc...)
  2. try to disable caching
  3. try to disable virtualization
  4. try to use the onboard sound with the updated drivers

  Make sure you have the latest chipset drivers installed with the latest BIOS.

  WARNING OF THE BIOS:

  Change (CMOS) BIOS/complementary metal oxide semiconductor settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  I also suggest you to download and install the latest drivers updated.

• Satellite A210 - 1 4 frequently freezes when starting Windows 7

  Hello

  I have a laptop Toshiba Satellite A210 - 1 4 and updated upgraded to Windows 7 later. I have a problem in which case frequently the OS crashes during startup. This often happens and happens after the text "Starting Windows" appears, but before the windows logo appears. In this case I have to press CTRL + ALT + DELETE to reset the system and bring back to life, Windows 7 starts normally after that.

  I tried to reinstall Windows 7 and it still does not work. I use the 32 bit version if that makes a difference. I installed all the drivers of Toshiba using the [Toshiba Software Installer | http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/downloadDetail.jsp?soid=2475695&pf=true] and the problem still persists.

  Thanks in advance,

  Hello

  Recommends checking the HARD drive first.

  There is a nice tool called Drive Fitness Test which can be downloaded from some 3rd party pages.
  The tool is free and helps you run HARD drive Diagnostics tests.
  If the HARD drive is ok, then the next step should be checking the RAM.

  Tools such as memtest86 + could be used to test the memory.

  But even if there is no error, the RAM could be affected again I recommend that you test the new notebook with Rams

  By the way: check if the BIOS is up to date!

• Problem starting SQL Developer

  Hello
  
  I have a little confusing problem on a Virtual Machine.
  I have a Windows Server 2003 R2 SP2 (32-bit) as a Virtual Machine. On this machine, I have two different versions of the SQL Developer:
  
  -SQL Developer 1.0.0.15.57
  -SQL Developer 2.1.
  
  When I try to start the sqldeveloper.exe for SQL Developer 2.1.1.64.39 I get the following error message:
  
  Windows cannot access the specified device, path or file. May not permissions to access you the item.
  
  The funny thing is, when I start the developer SQL 1.0.0.15.57 everything works fine.
  
  The authorization must be resolved I can start the 2.1.1.64.39 SQL Developer or someone has other solutions to this problem?
  
  Any help would be appreciated.
  
  Thanks in advance.
  
  Greetings.
  
  Edited by: user8950278 the 07.07.2010 09:46

  First of all, try to run once as an administrator, it could create the necessary associations.
  If this does not work, I would say that it could be related to parameters, which are now stored in the (hidden) of your Windows profile Application data. See that you have the permissions there.
  You can also run the \sqldeveloper\bin\sqldeveloper.exe, to see if you get all exceptions or more information in the console open.

  Hope that helps,

• Problem with Apex 5.0 report with a query that runs in SQL Developer

  Hello

  I have a query that runs in SQL Developer without problem, but when I use it in a classic report, it displays following:

  error report:

  ORA-06502: PL/SQL: digital or value error: character of number conversion error

  
  

  The query is:

  select

     AND REL_ID = 64146);
  

  
  

  And the output of SQL Developer is:

  

  I have following Setup for the BLOB_CONTENT column in the classic report:

  

  Any ideas what is causing this problem?

  Thanks in advance,

  I don't have notes with me, but I think that the content of the blob must be selected as:

  DBMS_LOB. GetLength (blob_content) as blob_content

  and check that you have included the primary key in the results.

• New versions of Sql Developer not showing do not export progress

  Hi, actually I was using SQL Developer to effect considered. The version I used was 3.0.04 and took me to Version 4.0.1.14 in earlier versions of SQL Developer (3.0.04) when I exported the query results that I would see a current account of the number of records exported in the lower left corner of the window. With 4.0.1.14 when I export all I see is a progress bar below on the right with the word 'RUN', but I don't get a count of the number of how many records were exported. Is this something that has been removed from more recent updates of SQL Developer?  The account running has been a very useful for large ensemble export, so that we can have a clear idea of the progress of the export.  Please any body can advice me how turn on the feature that displays the number of records exported.

  View > Task progress will show you a number of records running for your exports

• Need help on Sql Developer 4.0.0.13.30

  Hello

  I need a few suggestions if the underside of features/settings exist in the version of the sql developer said.

  When I open a new connection, a new code editor opens sometimes, sometimes it does not. It should open each time. Is there any setting for this?

  Can I get a list of all currently open windows in a corner of my window of developer sql (like its pl/sql developer tool, in the lower left corner)?

  I can cascade open windows? I can see vertical / horizontal / Float option window, but none cascading is here.

  Thank you

  If you click on the small blue arrow in the top right corner down - it will be on the same line as the list of tabs of the document - it will show you your list of open editors. Windows > Documents will also show you this.

• problem starting sql developer 4.1.1.19.59

  Hello

  I installed SQL developer 4.1.1.19.59, but when I start it up it crashes on the login window for the proxy server that is not responding. I can't even shut it down, and the only way is to kill the process with the Task Manager.

  An administrator can run the program, but I'm not an administrator on my PC.

  I'm runnning Windows 7 Professional 64 bit.

  Can someone tell me what permissions are needed to facilitate this run as a normal user?

  P.S. I don't have this problem with SQL Developer 4.0.3.16.84

  Thanks, Wouter

  HI Wouter,

  In fact, my advice was r ide.user.diuse to replace the default user settings folder.  Under normal circumstances the default value of %APPDATA%\SQL developer and the problem is usually an administrative policy that prevents updates records and files in %AppData%.

  My expectation was so you would set ide.user.dir to something other than a folder under % APPDATA %., maybe C:\Temp\OSD, to see if it works.

  Kind regards

• SQL Developer debugger does not start

  I found a strange behaviour, while debugging PL/SQL stored procedures using SQL Developer version 4.1.0.19 on Ubunto 12.04 LTS. The debugger works fine for all the bases of my company, except one. When I start a debugging session in this database, the debbuger let go forever and never debug dialog box open. When I use another IDE, for example, PL/SQL Developer of AllroundAutomations on Windows 7, the debugger works very well. I used the same user database with all necessary Preobrajensky. First I thought it was a bad configuration of the database, but as I could start with another IDE debugging sessions, I think that this is not the case. So, I would like to know if someone could help me understand what is happening.

  

  We opened a request for support at Oracle and they offer us to turn on an earlier version of the debugger to work around the problem:

  Add at the end of the file line-by-line ide.properties:

  DatabaseDebuggerDisableJDWP=true

  


  The ide.properties file can be found here (on Windows XP):

  C:\Documents and Settings\\Application Data\SQL Developer\system${VERSION} \o.sqldeveloper${SYSTEM_VERSION}

  


  or here (on Windows 7):

  C:\Users\\AppData\Roaming\SQL Developer\system${VERSION} \o.sqldeveloper.${SYSTEM_VERSION}

  for Linux users:

  $HOME/.sqldeveloper/system${VERSION}/o.sqldeveloper.${SYSTEM_VERSION}/ide.properties


  It works!

• -You also get an invalid identifier error when executing this query sql for a data model, but not in TOAD/SQL Developer?

  Hello OTN.

  I don't understand why my sql query will pass by in the data model of the BI Publisher. I created a new data model, chose the data source and type of Standard SQL = SQL. I tried several databases and all the same error in BI Publisher, but the application works well in TOAD / SQL Developer. So, I think it might be something with my case so I'm tender hand to you to try and let me know if you get the same result as me.

  The query is:

  SELECT to_char (to_date ('15-' |)) TO_CHAR(:P_MONTH) | » -'|| (To_char(:P_YEAR), "YYYY-DD-MONTH") - 90, "YYYYMM") as yrmth FROM DUAL

  
  

  Values of the variable:
  

  : P_MONTH = APRIL

  : P_YEAR = 2015

  I tried multiple variations and not had much luck. Here are the other options I've tried:

  WITH DATES AS

  (

  Select TO_NUMBER (decode (: P_MONTH, 'JANUARY', '01',))

  'FEBRUARY', '02',.

  'MARCH', '03'.

  'APRIL', '04'

  'JUNE', '06'.

  'JULY', '07',.

  'AUGUST', '08'.

  'SEPTEMBER', '09'.

  "DECEMBER", "12."

  '01')) as mth_nbr

  of the double

  OF DATES

  SELECT to_char (to_date ('15-' |: P_MONTH |)) » -'|| ((: P_YEAR, 'MONTH-DD-YYYY')-90, "YYYYMM") as yrmth FROM DUAL

  I'm running out of ideas and I don't know why it does not work. If anyone has any suggestions or ideas, please let me know. I always mark answers correct and useful in my thread and I appreciate all your help.

  Best regards

  -Konrad

  So I thought to it. It seems that there is a bug/lag between the guest screen that appears when you enter SQL in the data model and parameter values, to at model/value data.

  Here's how I solved my problem.

  I have created a new data model and first created all my settings required in the data model (including the default values without quotes, i.e. APRIL instead "Of APRIL") and then saved.

  Then I stuck my sql query in the data model and when I clicked ok, I entered my string values in the message box with single quotes (i.e. "in APRIL' instead of APRIL)

  After entering the values of string with single quotes in the dialog box, I was able to retrieve the columns in the data model and save.

  In the data tab, is no longer, I had to enter the values in single quotes, but entered values normally instead, and the code worked.

  It seems the box prompted to bind the values of the variables when the SQL text in a data model expects strings to be wrapped in single quotes, but no where else. It's a big headache for me, but I'm glad that I solved it, and I hope this can be of help to other institutions.

  See you soon.

  Nuke SQL Developer Directory for this version in your directory of Application data for the user of your operating system - should be under roaming profiles and start the SQL Developer.
