turn off your laptop remove battery and ac adapter and ram hold down power button for 30 sec and then plug them all in and turn on your laptop
That looks like something that will reset my computer and its been a while since I made this and some keys are starting to work again.
The proposed procedure does NOT reset your computer!
The procedure described is known as a "hard reset". If you think of electrical charge in your laptop as stress (not your battery, but the left-over electrical charges in the cords and metal and such inside your computer), this procedure relieves the stress of your computer, removing a lot of weird behavior, such as keyboard keys or lights going crazy; it can have an effect on anything connected to the computer, including peripherals plugged into the USB ports!
You should do this little procedure once in a while, since the less "stress" the internals of your computer are under, the longer it will last.
