The first problem I noticed was a windows 8.1 update that failed and was reverting to the previous version. A few days later I went to turn on my toshiba satellite laptop and I got a screen that said the hard drive recovery process has been selected select yes or no. I was able to select yes and get to the next screen for troubleshooting. I didn't make a selection at the time because I wasn't sure what option to choose. The next time I turned it on and tried to select yes to continue the hard drive recovery process, it would not allow me to continue to the next screen. It was stuck on the select yes or no to continue with the HD recovery process. After a couple of days I was able to get to the trouble shooting screen and selected the reset option. The laptop was able to boot up normally but I noticed there were certain keyboards that would not respond. Also when I would try to type my log lin password to get access to use the laptop, there were keys that I would tap once and it would act as if I was holding down the key and show up repetitively. So I had to change the log in password. Now I'm able to get to the desktop screen and select tabs but there are still many keys that are not functioning.
I am using OS WIN 8, on a Toshiba Satellite Laptop.
