I recently received a Hewlett Packard Laptop computer model 15AC121DX. I am going to walk you through the memory replacement process. There are twelve total screws that you will need to remove from this bottom cover.
You can place this laptop computer facing down. You will need to take out the battery. There are two plastic releases that you will need to use in order to remove this battery.
Once this laptop battery is removed, you will notice two small screws under the battery. You will want to remove these screws with a smaller phillips screwdriver. Now you will be able to remove the other ten larger laptop screws.
You will need a phillips screwdriver for those ten screws as well. Once you remove those ten screws you will want to remove the digital video disc optical drive. Once that optical drive is removed then you can go ahead and remove the bottom cover.
The easiest way to remove this bottom cover, is perhaps to place this laptop facing down. Now you will want to just pull up on the bottom cover. This cover should come off pretty easily, as long as you have removed all twelve screws.
There are two memory slots located in the center of this Hewlett Packard laptop computer model number 15AC121DX right next to the microprocessor heat sink. In order to remove one or both memory modules, you will want to just pull outwards on the two shiny metal releases. These memory modules will move up as long as the releases are pulled out.
Now you will want to just grab the memory module(s) by the end and pull them out of these slots. When you replace these memory modules, you will want to make sure to slide them flush and tight so that you cannot really see any of the metal contacts. Then just push down with your fingers on the edges of these random access memory modules until they are installed tight.
The two metal releases on each side will hold these memory modules in place. You have successfully replaced the random access memory on a Hewlett Packard laptop model number 15AC121DX. These instructions were written for a specific Hewlett Packard laptop computer.
