How to Find a Stolen iPad

Retrace your steps. If your property has been broken into or you have been mugged, then clearly your iPad can be classified as stolen. However, if it goes missing under vague circumstances, first make sure that someone has indeed taken it. Go back to the place where you think it was stolen and look around. Someone might have found it and turned it in. Ask store cashiers and restaurant waiters if they have a lost and found storage area.
File reports. When you are certain it has been stolen, go into your local police precinct and file a report of theft. Because it is a non-emergency, the police will more than likely not come to the place where the iPad was stolen. Once you get a case number from the police, call your property or renters insurance company to see if they will cover the iPad. You can give them your case number as a reference.
Lock the device. Your iPad may contain contact information, credit card accounts and sensitive emails. With your MobileMe service through Apple, you can lock your phone so that the thief cannot access any of your information. You will have had to set up the device beforehand with the 'Find my iPad' feature. Go to the MobileMe website and sign in. Click on the device that you want to lock. The iPad's built-in GPS will show you the device's approximate location. If you have already set up a four-digit passcode, then type that code in. If not, you will be prompted to type in a four-digit code and password.
Go to the location on the GPS. After you lock your device, use the map as a guide to find where the iPad is. The GPS will only give you an approximate location. It might be in the same place where you think it was stolen. If you come in contact with the person who you believe stole your iPad, do not try to confront them on your own. Call local law enforcement for help.

How to Increase Memory in a Macbook (5 Steps)

Turn the computer over so that you can see the screws around the perimeter of the bottom of the computer. Remove them using the phillips-head screwdriver, then place them to the side. There are two different length screws, so make sure you keep them separate and note which ones go where.
Lift the bottom of the case off of the laptop at the vents near the back of the case, which will also release the two clips which hold it in place. Set the bottom of the case to the side.
Locate the ram in the computer. This is on the left side, just below a fan, and is about two to three inches wide. Push the tabs on either side of the ram away from the ram chip itself, which will pop up the ram. Pull the ram straight out of the socket. If you're installing two ram chips, repeat the process for the second layer of ram just underneath the first.
Push the replacement ram into the socket and push the clips onto the sides of the ram. Repeat this process with the additional piece of ram if you are installing it as well.
Place the bottom cover back onto the computer and reinstall the screws using the phillips-head screwdriver. Turn on the computer. If the ram is not installed correctly, you will get an error message right off the bat, so go back in and double check to make sure that it's installed firmly in the socket.
