I hear whining, then rattling sound inside my Sony PCG GRT170

I have a Sony Vaio PCG GRT170 NOTEBOOK. When I turn it on i hear a whinning sound and after it gets to Windows desktop I hear rattling sound and the keyboard fills all text field it finds with an uncontrollable letter "T". I can go to the internet but then cannot type anything on a text box.

Take a close look at your keyboard. Does it look like the letter t is depressed all the time? If so remove the keycap and cycle the key manually until it stays up. If that doesn't solve your problem perform a safe boot and run your anti-virus and anti-malware software. Have you installed any software recently? If so you may need to delete it.

If nothing has worked to this point get back to us. Ralph
