Cleaning or Replacing Laptop RAM

RAM (random access memory) is a form of computer data storage. where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the device’s processor.

As with any circuit board component, the gold contacts at the bottom of your laptop’s RAM modules must be clean and free of debris in order to maintain a solid connection.
If the RAM sticks are dirty, the laptop might not recognize that they’re installed and may sometimes show a blue screen.
To replace or clean RAM module, shut down your laptop, unplug AC adapter and take out the battery. Press the power button on your laptop to remove any remaining electrical charge from internal components. Static electricity can damage your module and other computer parts. You need to ground yourself to avoid “shocking” your laptop.
Every laptop case is a little different, so consult your manual to find out where your SODIMM slots are located and how to open that part of your laptop case. Some of the most popular places for SODIMM slots are: Under the keyboard or Behind a back access panel. Locate the panel used for access to the memory modules, remove the screw(s) holding the door in place, pull off the door (RAM access panel) of your laptop case and set it aside. SODIMMs fit into slots that look like this. Some of your slots may be already filled with modules.
Remove the memory you want to clean or replace (if necessary). Use two fingers to push out the two latches holding the RAM stick in place. The RAM should pop upward at a 45-degree angle. Carefully slide the RAM from its slot at a 45-degree angle, holding the module by its edges.
Clean the contacts using a cotton swab slightly moistened with rubbing alcohol. Set the RAM module aside and allow it to dry completely. Blow out the empty RAM bay with canned air. While you’re at it, you might also want to dust the entire case out at the same time.
Replace the RAM stick after it’s dry by inserting it into its slot at a 45-degree angle and pushing it down until it snaps into place. Make sure you fill the bay on the bottom before the one on the top. Replace the RAM cover and its screw(s), and remove the anti-static strap if you used one. Reinstall the battery and power the laptop back on.
