You should just need to replace the keyboard.

However finding a keyboard for a packard bell in the US can be hard. That brand hasnt been sold here in years.

If you are in europe it should be less of a problem though.
Made sure to get the exact model of the laptop to get the right keyboard.

Good luck!

Yes but You need to tell your exact requirements eg. from where you would like to update your Invoice Template i.e from A Separate Database or from a Dropdown List etc

SOURCE: cannot insert columns in excel

This error message occurs if the following conditions are true:

• The option Nothing (hide objects) is selected in the Display options for this workbook section in the Excel Options dialog box.
• You create an object, such as a cell comment, in any cell in a column.
• You try to hide the column to the left of the column that contains the object, the column that contains the object, or all the columns to the right side of the column that contains the object. Or, in some cases, you try to insert a row or column in the worksheet.

1. In the upper-left corner of the Excel window, click the Microsoft Office button.
2. At the bottom of the menu, click Excel Options.
3. Click Advanced from list of options on the left.
4. Scroll down to the Display options for this workbook section, and then click All under For objects, show:, and then click OK.

1. If the object is a cell comment, select the cell that contains the comment, right-click the cell, and then click Show Comment or Show/Hide Comments. Note This makes the comment visible.
2. Move the pointer to the edge of the object until the pointer changes into a white arrow with four small black arrows on the pointer. Then, click the object to select it.
3. In Excel 2003 and earlier version of Excel, click <object name> on the Format menu. Note In this menu command, <object name> is the name of the object, such as "Comment" or "AutoShape."  In Excel 2007, click Format <object name>.
4. In the Format dialog box, click the Properties tab.
5. Click Move and size with cells, and then click OK.
6. If you want to hide the cell comment again, right-click the cell that contains the comment, and then click Hide Comment.
7. Follow these steps for each object in the affected column as described in the "Cause" section. When you hide the columns, you do not receive the error message.

I just had the same problem and was able to figure our a permanent fix.Judging by the date of you post, I'm guessing you've already remedied this problem one way or another. But just in case you haven't or someone else is having the same problem, I'll go ahead and post what to do. First, make sure you leave the USB hub plugged in right now so that Device Manager lists what it thinks is the Bluetooth device. Go into Control Manager > Hardware & Sound > Device Manager. Right click on Bluetooth device that is showing up in error. From the dropdown box, select Properties. Click the Driver Tab. Click Uninstall. Check "Delete the driver software for this device." Click OK. Unplug your USB hub for a few seconds, then plug it back in. Windows should now recognize it as a "Generic USB hub." You should be good to go. Just remember not to install that update again or try to update the driver for the Generic USB hub. If you do, you'll end up with the same problem. I hope this helps someone out there.
