[W520] [Dev] Qt Designer will not start

Hello!

I finally received my W520 last Friday and my first impression is really good.

Unfortunately I have a problem to start Qt Designer on it so if any C++ developer is around and not a clue, don't hesitate.

I use the Qt libs and the plugin for MS Visual Studio 2010.

I can run the demos, documentation, other programs, compile my project VS C++ and run it, but I can't access the designer. When I start (VS2010 or the installation folder) nothing happens on the screen.

Looking at the process manager, I see "designer.exe" in the list. It uses little memory, but no resource processor.

What I did to solve the problem:

-Google (found a nice deal close mine but no solution).

-Watch on the Lenovo forums (sorry if I missed a few posts).

-Uninstall + install libs Qt & VS plugin

-Check the missing DLL to a dependency walker (a lack but normal)

-Control with a colleague (Lenovo X121e) if we have a facility different folders content or missing dll.

My Configuration:

W520

Windows 7 x 64

I7 2.2GHz

6 GB of Ram

All software from Lenovo are installed (does not delete everything at the reception).

Does anyone ever experience this problem or have any idea to solve?

Thank you for your time.

Bastien

We had a few new T420 with Win7 x 64 with the same problem. QT Designer 4.6 / 4.8 was not visible began. The solution was to remove the preinstalled DVD Corel software. Now it's working.

    the cause.

    Some of the fundamental things include the pram/clock battery replacement

    since they may be dead; then with a power failure, sometimes the Mac

    do not restart. Usual power management unit & reset NVRAM/PRAM are

    methods that sometimes also used as a troubleshooting measure.

    A hard reset can sometimes be used, where the power is disconnected

    (But maybe not. Several PowerMac computers, I had, some people found this helpful)

    You may also remove and reposition cards and other items

    the inside of the case, to be sure they are connected properly. Be sure to not

    In short anything, due to the static load or residual power in the circuits.

    The hour is late here, so I'm not going offline; If all goes well a battery original or novel, etc.

    can help to put it on again. Also sometimes the power supply has some faulty fans,

    circuits or capacitors, so they can be troublesome to repair or replace.

    Good luck in this case!

    If you can't get the iMac began and ongoing implementation, you will not be able to use the target disk Mode:

  • Recovery disk will not start on Satellite 1110

    I try to use the recovery on a Satellite 1110 CD. I want to just install fresh Windows. The necessary files are supposed to be on the Toshiba recovery CD that accompanies it.

    So I did what the brochure says, and booted up the laptop to the top with the correct CD in the drive, while pressing 'C '. The notebook ignored the CD ROM and loaded Windows as usual. I repeated three times, each time that the CD ROM whirs a bit but will not start and Windows loads as usual. I have replaced 'C' for F12, chose the CD ROM drive in the list and repeat the process several times. Yet once it wouldn't boot from the CD-ROM.

    I looked at the content of the CD ROM A single MB 447. File of the GHS. The file icon is that generic type "Windows does not know what program this icon is intended to" deals.

    Google believes it is a ghost file and must the ghost installed to run it. This bitch never came with Ghost.

    Anyone here knows a remedy to this problem?

  • L50 - B satellite will not start when the battery is completely discharged

    Hello

    My Toshiba L50 - B won't start when the battery is fully drained but connected to the power outlet.
    I try to work most of the time on the battery to keep the battery in good shape, but when I forgot to turn off the battery drains and the system will not start when I plug in the adapter.

    The battery charge indicator is orange light as it should. Only when the battery is fully charged to 100%, it will run at startup and function normally after that. I tried to turn on the laptop several times during the charge cycle, but only when the charge indicator changes from yellow to white it starts. Tested for 2 bodies.

    My old Toshiba always immediately turned on when I plugged the adapter even when the battery has been completely drained. Am I missing a setting somewhere?

    Thanks for responding... I hope well :-)

    Toshiba L50 - B
    Windows 8.1
    Any standard/original setting since I only acquired this laptop a month ago.

    The laptop should light up if the power adapter is plugged in and power the laptop corectly any if the battery is empty or during charge.

    Please check the version of the BIOS that is available on your mobile phone and compare with the BIOS available on the page of the Toshiba UE driver
    Maybe you need to update the BIOS, but to be honest, the history seems really odd to me and I m afraid that there could be some power supply electronic problem

    So in the worst case, the laptop must be checked by authorized service provider.

    What you can try to do is, remove the laptop HARD drive and switch on and press F2.
    From my point of view of the rare even if the isn't HARD drive connected, you should be able to access the BIOS.
