  1. Hi There,

    I have a C660-195 and I have a problem where random keys don’t work on the in-built keyboard. I have updated the BIOS to the latest 1.40 version, but this has made no difference. I have also gone into the BIOS menu and reset to default and saved… this has also made no difference! Can someone please HELP!

  2. Hi Nav,
    First of all welcome to [FIX-KB], also I would like to point out at this stage the above fix has only been tried and tested on the C660-155 however this fix may be appropriate for other models.

    I have a few questions for you.

    1) Have you been experiencing this issue since you first got your laptop?
    2) You say “random keys don’t work” is this completely don’t work or intermittently?
    3) Do you have the same issue with an external keyboard?

  3. Hello,
    I am no computer guru however i had this extremely frustrating missing keystroke get my toshiba satellite p755 and it was driving me crazy, i tried everything i read about online to no avail…however this is what i figured out will work…well it did on mine…
    at the bottom right of your screen click on the arrow icon to show hidden icons, next the flag with the x over it labeled “solve PC issues”,
    next go to the bottom of it when it opens and click on “open action center”,
    then scroll all the way down to the bottom of that window and click on “recovery”,
    then click on “open system restore”,
    then click “next”,
    then check the box on the bottom left that says “open more restore points”,
    when this opens go back to a date before your computer started doing this keyboard missing thing, click on that and hit next and allow it to restore to that date, it may take about 10-mins. or so but then it will re-boot and hurray!!!!! it is like it used to be, i did not lose any files or anything, but i did go into my update controls and changed the settings so that windows does not automatically update anymore, now it asks me first and i get the option…

    hope this helps! 🙂
    GOD Bless!
