Q: 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.
A: 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.

Q: If the ceiling isn't very dirty, simply use a broom covered with a tee-shirt to dust away any dirt. If your ceiling is dirty or greasy, use a sponge to scrub one small section at a time using an all-purpose cleaner. It's important to let the ceiling dry thoroughly before applying your tiles. A clean surface will make your tiles stick more effectively. You may have trouble attaching them if the ceiling is dirty or has peeling paint. If your ceiling is very greasy, wash it using a mixture of 1 cup ammonia and half a gallon of water. To do this, use measuring tape and record how long the ceiling is. Then measure how wide the ceiling is. Multiply these two numbers to get your square footage. For example, if your ceiling is 12' long and 15' wide, then the square footage is 180. You'll need to figure the square footage of each tile. Again, multiply the length times the width to get the tile's measurement. Then divide the square footage of the ceiling by the square footage of one tile. This will tell you how many tiles you'll need. For example, if your tile is 24" long and 24" wide (2' by 2'), then the square footage for the tile is 4 (2 multiplied by 2). If the square footage for your room is 180, divide it by 4. You'll need at least 45 tiles. Always buy 15 percent more tiles than you think you'll need. That way, if you need to cut tiles or make a mistake, you'll have plenty to complete the job. Unscrew any light fixtures, fans, or air vent covers. This will allow you to easily measure tiles and install them without damaging fixtures. You'll probably want to use a flat-head or Phillips screwdriver to remove fixtures. This is also a good time to give fixtures and vents a quick clean.
A: Clean the ceiling. Measure the square footage of the room. Determine how many tiles you need. Remove any fixtures or vents.

Q: March, April, and May can be lovely but will still have their chilly and wet moments. It can also get pretty cold in the evenings throughout the spring season. Lighter shirts and slacks are good for this time of year. Spring colors come back into fashion as well, though some New Yorkers stick to black and other dark colors all year round. Plan to bring clothes that you can layer as temperatures can vary greatly in spring. For women: Lighter dresses come back into favor starting in spring so pack some of them in your bag. Pants with cute tanks and a light jacket are also a staple outfit. For men: Pants and solid colored shirts with a blazer are a standard outfit on the streets of New York. While it does get warmer, its still good to remember to pack some clothes that will keep you warm in the cold evenings. Some ideas include bulky sweaters you can wear over spandex, and light blazers. Regular sweatshirts, unless they are distressed, crop-top, or graphically enhanced, are a sure sign you are not a fashionable New Yorker.
A:
Know what spring in NYC is like. Plan for both warm and cold weather. Bring a jacket and some sweaters. Don't wear sweatshirts.
