I want to know the functions to all buttons for

it acts like a( tow asst )is used under heavy acceleration by keeping the transmission in a lower gear longer for power and faster pick up

Try going into the Control Panel and navigate to mouse properties. There is an option there to reverse the button functions.

The function button, or FN button, is used just like the shift key or ctrl key. Hold the FN button down and press the key with the pre programmed function you desire to use. For instance, on an HP 1245 the function or short cut key to put the computer in sleep mode is FN+F5. The Keys with functions have that feature indicated by a symbol for the function in a squared circle. Most of these are your F keys at the very top row of the keyboard. Some are on the number pad keys.

Here's a link to a pdf of the manual. The basics are that you have 12 white keys near the bottom, which include the 10 digits, a decimal, and the negative sign. On the right, you have the four operating keys, division, multiplication, subtraction, and addition. You also have the Enter key which will solve the expression. You'll notice that the buttons have blue and green lettering above them, and those are for the 2nd and alphabet functions. So if you press the 2nd key on the top-left, then the on key in the bottom left, then it'll turn it off, because it also functions as the off key. The Alpha key is used to input letters which are in green above each number. Good luck!

Turns on when the numeric keypad is enabled.
Turns on when the uppercase letter function is enabled.
Turns on when the scroll lock function is enabled.

The ECT button (which stands for "Electronically Controlled Transmission")
changes the shift points for the automatic transmission. When engaged,
the transmission shifts later, allowing the engine to get to a higher
power level and accelerate faster. Gas mileage is usually reduced in
this mode. Use it when you need to get up to speed faster; for example,
to merge into fast moving traffic. The normal position for this switch

Hope this help (remember comment and rated this post).

Generally in notebooks, there is a function button, can be seen as "FN", on the left bottom corner, either on the left of the "Ctrl" button or on the right of it. You can press and hold that button, then while holding it you can find the "F#" (# is from 1-12, but you should find the correct one with a small webcam icon on the top of it, and you should only press that one) button that stands for webcam function and press it while pressing the "FN" button. Doing this process again will close that function again. And when you open the webcam, you can test it simply by going into "My Computer" folder.

Hello there.

The W/S mode button stands for Winter and Standard. Winter mode increases torque and thus adherence when starting. I believe that under normal conditions, standard mode is to be prefered as it improves acceleration and makes the ride more comfortable.

The ACR button inhibits the electronic drive assistance. This again might be necessary when driving under certain winter-conditions (snow, ice), but should normally be let active.

Hold down the function button and press one of the arrow buttons (probally the 'up' button). The function button is the one with the letters 'Fn' on it, on the left side near the bottom.
Good luck, and please rate my answer.

with a compressed air can be sure to clean everything inside the keyboard.
Let me know if it's enough and don't forget to rate the solution.
thanks
