Panels in my Ubuntu9.04 desktop are not responding. When I click on them nothing happens. This happened when I added many Panels and tried to delete them. I think that I had clicked on autohide button....


Dear rajendran102, there are many bugs and problems with Ubuntu's 9.04 version. It is advised to upgrade to 9.10 to fix most bugs. To upgrade, simply follow these instructions: - Click on System, then on Administration. Now click on "Update Manager". - Click on "Check" and enter your sudo password. Download and install the updates, then on the top, click on "Upgrade to 9.10". - After downloading and installing, it shall reboot the system, and you will have Ubuntu's 9.10 version installed.
Do not worry, your files won't be deleted. After the upgrade, everything shall work normally. And if you want, you can follow the same steps, after upgrading to 9.10, so you can upgrade to 10.04 LTS.

I states than there is no driver instaled for it and when i look for it i cannot find it ihave the ti connect but it cantfind my calculator


This should help you install the drivers so that your calculator can communicate with your computer (Windows-based). Please read the post to the end. If you have any problem, post a comment to this thread.

Install TI Connect 1.6 for Windows then try connecting the calculator to the computer using the TI SilverLink cable (if you have one). It goes into the Round IO port.

If you do not have a USB SilverLink cable, you can use the mini USB to USB Direct cable but you will have to install the correct driver for it.

I do not know what computer operating system you are running and I use Windows XP so I will describe the installation procedure for Window XP SP3.

Install TI connect 1.6 for Windows; if your system is Vista you must install a patch available on the TI website, at the same page where you find TI Connect.

After you install TI Connect, connect you calculator to the computer with the mini USB standard USB Direct cable. Windows will detect the calculator and will try to install the drivers. You will have something that is similar to what is on the three screen captures I am inserting in the post. On the last screen, choose the TI Educational Handheld device and click next.

When Windows asks to stop installation, click continue anyway

After the installation, click finish.

Device manager will show you something like what is on next screen (TI Educational Handheld device)

Run TI Connect to verify that the calculator is recognized. Connect your computer to the Internet and click the Updates Button on the TI Connect tool bar.

Verify that the I/O port (the round one) does not contain any foreign material. Also, for transferring files batteries must be in excellent condition.


Suggestion: If you are able to establish communication with the calculator through TI Connect software, you should consider upgrading the OS to version 2.53 MP. It is a major upgrade for the OS of TI84Plus (not the TI83Plus).

Reinstalling the OS fot the TI84Plus

How do I correct the Error Waiting...Please Install Calculator SoftwareNow message on my TI-83 Plus family or TI-84 Plus family calculator?

If an operating system (OS) update fails or is interrupted, the calculator will be in an inoperable state with the message Waiting...Please install calculator software now.The most common cause of a transfer being interrupted is updating the operating system on a calculator with low batteries. Users will need to use the TI Connectivity cable and the TI Connect to send the operating system to the calculator. Make sure to have the latest version of TI Connect installed on the computer.
In order to install the software please follow these steps:
1. Connect the TI Connectivity cable between the computer and the calculator.
2. Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
3. Follow the on-screen directions to reinstall the calculator's OS.
If the message "Error! Press any key to turn unit off. Then turn unit back on." appears on the graphing calculator, quickly, remove one battery from the calculator and reinstall it while the transfer is taking place.

Error message for TI-84 Plus


Try and resolve this issue by re-installing the calculator's operating system using the TI OS Downloader. To do this, please follow the steps listed below. Be sure you have fresh batteries in your calculator.

1. Download the OS 2.43 file to your computer (preferably the desktop).

2. Open the TI OS Downloader by going to Start>>Programs>>TI Tools>>TI Connect>>TI OS Downloader. If you do not see TI OS Downloader, you may need to install the latest version of TI Connect. You can download a free copy from:
www.education.ti.com/downloadticonnect

3. From the main screen, select your calculator and cable type. Click "Next" to continue.

4. From this screen, locate the OS 2.43 file by clicking on the yellow browse folder and navigating to the location where you downloaded it. Double-click the OS 2.43 file to select it.

5. Remove one triple A battery from your TI-84 Plus. With the battery removed, press and hold the [DEL] key while you re-insert the battery.

6. You should see a "Waiting..." message on the screen of your calculator. If so, disconnect the USB cable from your computer, re-connect it and then click "Start Download". This should begin the OS transfer process.
