If you want to use blue print Fn key, just press and hold it with any other key that also has blue print in it. Fn key is locaded bottom left of the keyboard. Second one from the left to be exact.

If you want to use Function keys F1, F2 and so on. You should not press Fn key which will change Function keys to function differently.

Your laptop is trying to boot from network. Pressing the del key after turn the laptop one, access to bios and change the boot order. Hdd should be in first place.

try another key it sounds like the imoblizer

There are 2 possible answers to this common issue, the first is that the aspire has a mouse lock. check your keyboard on the function buttons for a picture of a mouse with a line though it, hit function and at the same time press the mouse with the line through it and if its locked off this will turn if back on. The second answer is driver issues, if the first suggestion dont work I would go to the Acer website click on downloads and drivers and enter your model number. Then download and install your think-pad and mouse pad drivers and install.

Normally if you press the menu key while in a call it will give you this option, however would need to know exactly which phone before giving a definitive answer.

Without knowing the exact model of your machine I will give yu thi generic answer for most Brother electronic typewriters.
1. Depress the return key so the carrier is at the LH margin
2. Depress the M Rel (margin release) key or function(this may be a CODE + KEY function if the M REL is imprinted on the cover above the number KEYS.
3. Depress the BACKSPACE key until you are at the position you want the left margin location
4. Depress the Margin Set key or function

To do fractions, just use the normal divide button.
To see the exact answer, hit MODE and scroll down to Exact/Approx and change to EXACT. In this mode, it will give the fraction always unless you press the special (green button with diamond) before pressing ENTER and it will give the approximate decimal value.

There isn't anything "wrong" with it.

Go to mode, and set the results of your inquiries from Exact to approx.

If you put in cos(e^2), it will print out cos(e^2) because it's the most exact it can be without going into a decimal. (cos(e^2) will be a transcendental number like Pi).
