HP 255 G4: problem with sensitivity to the touch and slider jump

My question - problem could be funny, but it's a problem.

I bought HP 255 nine G4, from the box. First impression was: a pleasant experience, but first touch was terrible. I had several laptops, but never the same problem: cursor is wavering and being so inprecise it is almost impossible to locate some details using the key.

I have included a picture of the surface of the laptop. Should I maybe take off this perforated layer and reach the brilliant below surface? I tried to peel on the rounded corners, but he can't go easily, so I didn't damage it.

Please give me a sugestion. :-)

I'll answer myself, could someone help.

When I installed WIN 10, all problems are gone.

With WIN 7, nothing worked, I was responsible for the search and looking for drivers, but USB 3.0 has not worked, F keys did not work, touchpad was terrible, all together, very bad.

With 10 WIN, everything worked, only a few development was necessary.

With the new computer (product end of September 2015) the new system (WIN 10) so enjoy.

  • Problem with keyboard on the M60 (characters to jump)

    I bought an M60 for my wife and she complained that he jumps constantly characters. I found the same problem. For example, type in the URLS in internet explore or composing emails, he will be missed by 10% of the time characters. I saw a couple of posting on this topic in the forums.

    Good old Dixons refused to refund purchases as someone called me today to say that she cannot see any problem with the keyboard.

    Does anyone know a solution to this problem?

    Hello Chris

    Unfortunately, the problem can be fixed with some kind of firmware. I spoke with Toshiba and this is known issue and they also said that Toshiba do some tests with the new keyboards and when this will be resolved customers can expect a help about it.

    If I understand right, there is a problem with the contacts of the button. As you know that it is the new keyboard with numeric keypad and not the standard. Sorry, but for now, need you a little patience. If you want you can also try to contact the after-sales Service of Toshiba partner in your country. Maybe they have the same information. Talk with them. A consultation is free.

    Good luck!

  • Problem with LDAP in the APEX and not in sql query * more

    Hello everyone.

    Hereby, I refer to an existing thread: Query LDAP APEX

    I have a problem using LDAP in the APEX (DB version: 11.2.0.2.0;) APEX version: 4.0)

    I get "Authentication failed" by their SUMMIT. However, when I run it in SQL * more (SQL Developer) (I created it as seen in the referenced forum thread) it works! Can I use my own function, but that looks like reinventing the wheel.
        l_ldap_host := 'oursite.be';
        l_ldap_port := '389';
        l_ldap_domn := 'oursite';
        l_ldap_user := i_username;
        l_ldap_pass := i_pw;
        l_ldap_base := 'ou=oursite,dc=oursite,dc=be';
    
    
        dbms_ldap.use_exception := true;
        
        l_session  := dbms_ldap.init(l_ldap_host,l_ldap_port);
        l_retval   := dbms_ldap.simple_bind_s(l_session, l_ldap_domn||'\'||l_ldap_user, l_ldap_pass);    
        l_attrs(1) := 'name';
        l_attrs(2) := 'title';
        l_retval   := dbms_ldap.search_s(
                        l_session, 
                        l_ldap_base, 
                        dbms_ldap.scope_subtree, 
                        '(sAMAccountName='||l_ldap_user||')',
                        l_attrs,
                        0,
                        l_message
                      );
    
        l_retval := dbms_ldap.count_entries(l_session, l_message);
    We must search the sAMAccountName because that contains our login credentials (dennis.surname). The common name is just our full name (Dennis Surname)


    At the SUMMIT, I have these settings:

    * LDAP host: oursite.be
    * Port: 389
    Use SSL: No SSL
    Use exact DN: No.
    * String DN: ou = oursite, dc = oursite, dc = be
    * Search filter: sAMAccountName = % LDAP_USER %


    When I try to test it I get "Authentication failed" but I don't know why. It works very well in sql * more (in the the same pattern of course!) so I have really no idea what I'm doing wrong. In addition, the message comes instantly and sql * more it takes about a second to authenticate.

    I tried so many things! remove the 'or '. Connect with my name, change 'cn = % LDAP_USER %' filter, connect with dennis.surname and Dennis Surname, using exact DN,... and all the possible combinations of them... Nothing works.

    I can go further by using my own function, but I really want to use the settings of the APEX, because it's so much easier.

    Thanks in advance for help out me!
    Dennis

    Hi Dennis,

    Try this

    The exact use DN Yes value
    Change your DN string to

    %LDAP_USER%@domain
    

    or

    domain\%LDAP_USER%
    

    The authentication uses a simple_bind_s. You must use the same syntax in these text boxes. You actually do a single with bond

    dbms_ldap.simple_bind_s(l_session, 'sAMAccountName=' || l_ldap_user, l_ldap_pass);
    

    It does not work. It's the syntax to use in the search for search_s filter.

    Please keep in mind that the apex_040100 (for apex 4.1) user must connect the rights on the domain server.

  • Problem with menus on the right and the image is too right.

    Note the difference in size of menus, (unusual with the correct terminology). I can't the adjustments, layers, properties, etc. for all have the same size, increase width. Note that the loaded image is too far to the right under the menus. I have to go to the window/rearrange/float in the window to move the image to the left. Also I can not get the expand/collapse button to work. How can I solve these problems.

    Capture.JPG

    Try the Menu window > workspace > Essentials or Reset Essentials.

    ALT - w is the shortcut key for the menu of the window. (Windows OS)

    ALT-space you will get the menu resize, if you can not reach the buttons on the main window of the program.

  • Problem with using of the audit and the APEX triggers

    Hello community,

    I have a little problem with the help of a trigger to audit. I can't operate the trigger takes the reality of the user to record in the audit table:

    Column AUDIT_USER always gets "APEX_PUBLIC_USER" as a value of insertion. How can I change to the user real "& APP_USER."?
    I tried under Home > Application Builder > application 100 > shared components > change attributes for security > authentication > Public user
    And added & APP_USER. and: P101_USERNAME both have not changed anything.

    Is there a way to get to work with & APP_USER. instead of APEX_PUBLIC_USER?

    I use the standard authentication scheme 'Application Express'. I use ldap via a process to the login page.

    Kind regards

    Tobias

    Hello Tobias,.

    In the trigger instead of the USER code, use v('APP_USER') to catch the real user of APEX.

  • Weird problem with control of the ring and foot

    So I have some sort of weird issue with a control of the ring and a chart. I'm with LabWindows/CVI on a Windows 7 computer. The part of the program I'm looking at is basically to navigate through data - there are several "transition" (rehearsals experience), and you can choose the one that you want to watch in the list.

    Normally, you would select transitional in the list, it plots the data, then it is done, basically. However, all of a sudden (don't know how long it spent for), when I select anything except 'Average', he made all the tracing and such, then it changes control of the ring to 'Average' (it is not plot the average data or generate all the reminders that I can tell).

    Now the thing the more bizarre as you can see below, it seems that the switch happens just when I draw something on the chart:

     

    So, it's just weird. The code in this section is here:

       if(uidc.polyon) {
                polynomial_subtraction(curr_data, np, uidc.polyord, 0); // 0 Skip for now
            }
    
            // Scale the curr_data for gains, then pre-scale the FFT data
            // to have no change in the power spectrum (multiply by (2/np)
            for(j = 0; j < np; j++) {
                fft_data[j] = curr_data[j]*2/np;
                curr_data[j] = curr_data[j]*uidc.fgain[i] + uidc.foff[i];
            }
    
            uidc.fplotids[i] = PlotY(dc.fid, dc.fgraph, curr_data, np, VAL_DOUBLE, VAL_THIN_LINE, VAL_NO_POINT, VAL_SOLID, 1, uidc.fchans[i]?uidc.fcol[i]:VAL_TRANSPARENT);
    
            // Prepare the data.
            FFTEx(fft_data, np, npfft, NULL, FALSE, curr_fft);  // Do the fourier transform
    

    DC is a structure that I use to better organize some UI controls and uidc is for display RAM variables, then dc.fid is the Panel that is embedded in the tab "FID", dc.fgraph = FID_Graph and corresponds to the chart control. Control of the ring is actually in a child Panel, dc.cloc [0]. FID_Graph has a point, it can produce, but the reminder is empty (no not coded something there yet).

    I have also considered that perhaps something in another thread (I don't think there is, but whatever) I see is the cause, however, this behavior still happens on that line. I tried to break in different locations, on hold, then continues, as well by adding a loop containing Delay (0.01), a loop of 100 times. Always happens after the conspiracy.

    Does anyone have any idea why this might be happening?

    Hi Paul,.

    I don't have a solution, but I wanted to point out that, even if you see the ring to change its value only when you call the function of tracing, that doesn't say what this function call that really changes the value of the ring. In CVI, some drawing operations are batched, for performance reasons, and the Panel updates only visually at certain times. One of those moments when you draw a chart data. Yes, the ring changes visually at this time there, but it is probably just 'catch up' a change earlier.

    As you are looking through the code, when the value of the ring, you can use the term > command update UI to force the update panel, so that you don't have to wait for the tracing function and see if all goes well this change happening earlier.

  • Problem with image extract the content and the tile at the same time show on ListField

    My application is Application News get JSON webservice to appear on ListField.

    On each line in the list, it will show you the image thumbnail, title and Teaser as below.

    _______________________________________

    |                |                       Title

    |   Thumb  |_______________________________

    |_______  |                       Teaser

    First of all, I have to get JSON that contains the url of the thumbnail image, title and Teaser.


    I managed to view the title and Teaser, but the thumbnail is not. When I Fetch image with the url of the thumbnail image, it returns only bitmap = null for me.

    My method is first call httpdispatcher to get the thumbnail image, title and Teaser and then wait and call another httpdispatcher to retrieve the url of the image thumbnail, then added to listfield.

    Here is my code

    Class helloScreen{
    
    public void requestSucceeded(byte[] result, String contentType)   {      if (contentType.equals("image/png") ||        contentType.equals("image/jpeg") || contentType.equals("image/gif") ||contentType.equals("image/jpg")) {         bitmap_temp = Bitmap.createBitmapFromBytes(result, 0, result.length, 1);                     synchronized (UiApplication.getEventLock()) {

    httpRequest, class Dispatcher is used to get the data from the url

        int bytesRead = responseData.read(buffer);
        while(bytesRead > 0) {
        baos.write(buffer, 0, bytesRead);
        bytesRead = responseData.read(buffer);
        }
        baos.close();

    The point here is that I have JSON and get the url of the thumbnail to fetch before add to listfield. The image should be ready in bitmap_temp but it still get null.

    UiApplication.getUiApplication().invokeAndWait(new Runnable() {
    
                                   public void run() {

    public void getImageURL(String url) {                HttpRequestDispatcher dispatcher2 = new HttpRequestDispatcher(url,                "GET", this);    }
    
    callback.insert(j.get("title")+" ", ""+get_htmlOff_first.trim(), bitmap_temp , temp_int_next , "Event");

  • Problem with security of the ports and disabled learning MAC addresses?

    Hello

    Is there a problem, or incompatibility, if you configure the port-security on "n" ports that belong to X vlan and also disable mac-address-table of learning on this vlan?

    Someone did he do reference, links or PDFs on this problem?

    Thank you very much

    Hi Javier,

    As I showed above, the combination is valid. I did not all static entries in the security of the ports, but all entries learned through port security will be shown as static on the show see the mac address table. All dynamic learning is disabled.

  • Problems with synchronization of the settings and the list of sites

    Hello!

    Recently got Adobe Creative Cloud CC 2015 but I'm a little disappointed that the version of cloud does not behave like a cloud version. Dreamweaver CM³ in synchronization settings, I set always use the Cloud version and then import the sync settings. Everything is marked in sync settings. My main computer at home has welcome screen off, and he has two sites in the list of sites. At work, I have always the Welcome screen and 1 single site in the site list. Tried to restart and apply updates whenever he says but its not doing anything.

    Hi Johnny,.

    We will not sync preference screen between different versions.

    In regards to the sites not getting not migrated, could you please follow the mentioned below as follows:

    1. open Dw CC and create a new site (dummy) and synchronize it to the cloud. This will ensure that all sites are synchronized to the cloud.

    2. close Dw CC and open Dw CC 2015, go to the Preferences dialog box > synchronize settings category and check the box "import the sync settings.

    3. close the Dw CC 2015 and restart the application. Let the full synchronization and push the button apply. This will get all the settings from the previous version.

    Let me know if you need help most.

    Thank you

  • Problem with Vista hit the Satellite X 200 - 20 s

    Sometimes during typing on vista, it will stutter and freeze. The time is very short. Is this a problem with vista or the laptop. The T7300 Core 2 Duo 2 ghz processor.

    Hello

    I have a Satellite Pro S200 and the same problem was with my camera. It s is not a hardware problem, it s more a driver related issue No. So, the best thing you can do is update your bios and keep your drivers up-to-date. Just check the download Drivers Toshiba site and make sure you have the latest drivers installed.

    I had resolved my stuttering (core2duo 2.33 Ghz, 2 GB RAM) by updating all drivers...

    That's all

    Good bye

  • a problem with one of the files in the TestStand\AdapterSupport\LabVIEW directory

    When looking at the module a LabVIEW VI called for TestStand, I get the following message:

    A problem with one of the files in the TestStand\AdapterSupport\LabVIEW directory.  Please reinstall or repair.

    I made the mistake of cleaning C: in my computer.  Clean the C:\National Instruments downloads

    Why would someone put bits of applications or modules, etc. in such a directory?

    I'm not too crazy about restoring 11FR in this folder.  It's just crazy!

    If anyone has encountered this before?  No "easy"? outside re - install TS...

    Side note: I do not touch anything in the \Program files. National Instruments\TestStand\AdapterSupport\LabVIEW

    What version of LabVIEW and TestStand do you use?

    In 2012, TestStand, this directory is mapped to:

    C:\Documents and Settings\All Users\Documents\National Instruments\TestStand 2012\AdapterSupport\LabVIEW

    Have you tried mass compiling the screws in this folder?

    I had to create a new 'TestStand - default values XX.llb"file, where XX is the last version of LabVIEW you use, but I have not seen this message before.

    Good luck
