Introduction
Go to step 1 ↓One of the most vital components to any electronic device is of course, the battery. (After all, it wouldn’t run at all without this) which is why it’s important to be able to know what to do when it gets damaged or straight up broken. The following guide will teach you in simple steps what you need to do when you are replacing the battery of your ASUS Q405U. (Proceed with caution using these tools around battery because they could accidentally puncture the battery)

Disconnect the 4 wires attached from the keyboard side of laptop to the screen side of laptop by pulling them out of their sockets on one end (as shown in picture).

OPTIONAL: Additional pictures to demonstrate moving keyboard out of the way without detaching connections.

Lift the ribbon cable with gentle pressure, pry the ribbon away from the motherboard on the right side, then the left, then the center, prying away only a little triangle of tape at a time, applying gentle upward pressure to the tape while you loosen and pry.

Once you have enough slack in the three ribbons that hold the keyboard down too tightly, lift the front of the keyboard and twist counterclockwise to produce enough room to reach the screws securing the hard drive with your screwdriver.

Using the Phillips #1 screwdriver, remove the four 1.5 mm screws securing the battery to the device.

I had to remove two other screws from right side where the hard drive is and an extra screw from Step 4 picture. Also I had to remove the wifi card (or the antennas)
