This is a very problem and the steps to resolve this issue varies according to the specification of your laptop.
I am providing some of the basic steps which you can try, but before you try any of these, just make sure your Esc key isn't stuck down. That's the easiest fix.
Fix #1: Go to registry HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\. Look for and delete the graphic number ( a square or an L) located before zone number 0. If it's not there, this isn't your fix.
Fix #2: Look for "Send to Bluetooth" add-in under each office program and delete it. Find it under Options, Add-ins. If it's not listed, you don't have the add-in and it's not the problem. If you see it, go to Manage, Select COM add-ins and click Go. Check the box next to the add in and click Remove.
Fix #3: Click the Start/Windows button, Type Go to Start (Start/Run) type the following in the search box: cmd /c “echo off | clip” (including the quotes) then hit Enter. Note that there is a space between "cmd" and "/" but nowhere else.
Fix #4: Make sure you are using the most recent version of Flash Player. If not, update it.
If these fixes do not work, then there is a problem associated with specific applications while copying or pasting it from/to Microsoft Office:
If you using Remote Desktop: Open task manager, end the RDPCLIP.EXE process, and then restart the task. To restart the task, go to applications tab, click new task and type in rdpclip.exe.
If you use Advanced System Care 5 from IOBIT (ASC): Open the ASC Toolbox. Under Optimize, Smart RAM, Settings, uncheck "Clean Clipboard".
If You use Skype: Delete the Add-ins for IE and Firefox (Skype might also cause problems when using the Click to Call feature in Chrome). Then re-install the latest version.
If the problem occurs in IE: Go to Internet Options, Advanced tab. Click Reset under Reset Internet Explorer Settings. Click OK. This fixes problems associated with malware.
If you use Microsoft visual C++ 2005 (needed by some programs to work): Try uninstalling it if you don't absolutely need it. If you do need it, try Fix #4.
If you use Adobe Acrobat: Try uninstalling it. Might need to use Foxit Reader instead.
When I connect an external microphone to the jack, it is not working. I can see it in the "Sound" tab, but the levels is very low. I have tried with several microphones.
