Currently I'm working to fix my nephew's Windows 8.1 Hp Pavilion 15 Laptop. About a month ago he noticed that the "B" & "N" buttons on the laptop's keypad/keyboard was not performing properly. Whenever he'd use Window's Notepad or any other program that would allow the user to type messages or text, the "b" & "n" keys when pressed would automatically delete text when the cursor was moved to middle of a sentence; the letters to the right of the cursor would delete. He first noticed this when he was typing messages in Skype to his friends back and forth. Additionally, he noticed that when the letters were pressed an audio sounding "bing" would come through the speakers while in Skype. After doing my own inquiry, I found a much larger problem. It seem that the "B" and "N" buttons engage an "ins" insert key type overwrite that not only deletes text, but also deletes programs (pressing ins key does not fix it). If the last letter that is typed in any program or search bar is an B or N it engages something that deletes everything when I click on any file or desktop application. Suddenly the application or file ends up in my recycle bin folder, upon which they can not be restored to their previous location. The only work-around that we can use currently is to not engage the delete function by not using those letters or to use an on-screen keyboard.
THINGS THAT I'VE ALREADY TRIED TO FIX THE ISSUE ARE:
-Various scans by malewarebytes, Superantispyware, various anti virus programs etc.
-uninstalled skype along with other apps dated back to about a month ago.
-Performed CHKDSK scan in command prompt.
-finally I performed a systems restore back to factory only settings, deleting everything in my hard drive that didn't come with the laptop.
THE PROBLEM IS STILL THERE! Thanks for any help!
