This reduces the chance of damage to you and your computer. Remove the stuck key with a small, flat head screwdriver. Start by lifting each corner of the key, listening and feeling for a snap as it unhooks. Repeat with each corner until the key is removed, after two to four snaps. Use light pressure only. If the key doesn't pop out, try a different corner. To remove larger keys, such as the Shift key and Space bar, lever from the top of the key (the side nearest the laptop screen). These can cause the key to stick. Remove small objects with a pair of tweezers. Remove loose dust or animal fur with compressed air or a gentle vacuum cleaner hose attachment. If you've spilled materials on the keyboard, remove the residue with a lint-free cloth. Dampen the cloth with a small amount of rubbing alcohol and wipe the sticky area gently. Leave the key cap off until the rubbing alcohol has fully evaporated and the area is dry. The retaining clip, most often made out of white plastic, consists of two thin, square objects hooked around each other. These should be firmly attached to the keyboard, and to each other. If they are not, remove the clip by gently twisting the corners free with a screwdriver. See below for detailed instructions on replacing them. This nipple-shaped membrane sits beneath the center of the key. Confirm that it is standing up, and try to depress it with a very gentle touch from a clean, soft object. If it sticks in the down position instead of popping back up, it needs cleaning or replacement. Do not touch it with a dirty or sharp object. This part of the keyboard is easily damaged. Clean with a lint-free cloth dampened slightly with rubbing alcohol. Pat with extreme care and wait for it to dry. Before you begin, realize that this is a risky fix, and could ruin the key if you use too much glue. For a more reliable repair, take the keyboard to a computer repair professional to replace the entire keyboard. If you do decide to try this yourself, do so as follows: Very carefully remove a membrane from a key you don't use by levering it off with a sharp knife. It is very easy to damage the membrane this way, but this is usually your only source of replacement membranes. Use a toothpick to place a dab of strong glue, such as silicone adhesive, onto a sheet of paper. Pick up the membrane with tweezers and lower it onto the sheet of paper, then transfer it onto the keyboard. Let sit for at least 30 minutes, or according to adhesive label instructions. Reattach the retainer and key cap on top of this, and let sit another 20 minutes before using.

summary: Turn off and unplug your computer. Lever out the key with a screwdriver. Look for dirt or small objects. Clean up spills. Examine the retaining clip. Check the silicone rubber membrane. Glue down a new membrane.

It's a light-blue "e" with a yellow band wrapped around it. This option is in the upper-left side of the Internet Explorer window. A drop-down menu will appear. If you don't see File here, press Alt on your computer's keyboard to prompt it to appear. You'll find this option at the bottom of the drop-down menu. Doing so opens a new window. It's at the top of the window. If you'd rather import a bookmarks file from your computer, check the "Import from a file" box instead. This option is in the bottom-right corner of the window. Check the box to the left of the browser(s) from which you want to import bookmarks. If you're importing a file, you'll instead select items to import (e.g., Favorites, Cookies, etc.). If you don't see your preferred browser here, click Back, check "Import from file", click Next, and select items to import. It's in the bottom-right corner of the window. This will prompt Internet Explorer to import the bookmarks directly from your selected browser. If you're importing a file, you'll instead click Next. You'll then click Browse, go to your bookmarks file's location, click it, and click Open, then click Next and click Import.

summary: Open Internet Explorer. Click File. Click Import and export. Check the "Import from another browser" box. Click Next. Select a browser. Click Import.

Summarize the following:
The polygon can have any number of sides and can be regular or irregular. For example, you might want to find the sum of the interior angles of a hexagon, so you would draw a six-sided shape. Label this vertex A. A vertex is a point where two sides of a polygon meet. The lines should not cross. You should create a number of triangles. You do not have to draw lines to the adjacent vertices, since they are already connected by a side. For example, for a hexagon you should draw three lines, dividing the shape into 4 triangles. Since there are 180 degrees in a triangle, by multiplying the number of triangles in your polygon by 180, you can find the sum of the interior angles of your polygon. For example, since you divided your hexagon into 4 triangles, you would calculate 4180=720{\displaystyle 4 imes 180=720} to find a total of 720 degrees in the interior of your polygon.
summary: Draw the polygon whose angles you need to sum. Choose one vertex. Draw a straight line from Point A to each other vertex in the polygon. Multiply the number of triangles you created by 180.
