If this step is not done, your system won’t boot at all after chip Installation. Once the update is done, then move on to the next step.

Step2: Remove the Battery

This is the easiest step as you all know. If you are new to this then go through the user manual once. Remove the battery and dummy card. If there is an internal battery then take extra caution while removing it as current is still available in a portion of the motherboard.

Step 3: Remove the Back Cover

Disconnect the internal and external power sources before trying to remove the back cover. With the help of screwdrivers softly remove the back cover. Now you shall be able to see the processor, if not then remove the upper part as well.

Remove all the screws present on the backside even the hidden tiny ones. Along with this if any part is detached like the hard disk drive then keep it aside safely.

Step 4: Remove the Keyboard

As all the screws from the backside have been removed, the keyboard, DVD writer, and the wireless adapter must be loosened now. Gently take out the keyboard and remove the ribbon cable. Take out the DVD writer and Wireless adapter as well. Handle these portions with extreme care.

Place the new CPU in the socket and look for the proper alignment. Recheck the placement, if it needs a little push then there is a problem with alignment. Screw the socket again and if there is any locking bar present then lock it properly.
