Before starting, make sure your laptop is fully powered off and unplugged from any power source. Use the right tools—typically a screwdriver set included in the package—and work on a non-conductive surface to prevent static electricity damage. It's also wise to wear anti-static wristbands to protect sensitive components.
This tutorial will guide you in detail how to remove the Dell 33YDH / Inspiron 15 7577 / Inspiron 17 7778 / Vostro 15 7580 / Latitude 13 3380 Series laptop battery. You can watch the tutorial video below.
Step 1
Remove all screws from the bottom of the laptop, as shown in the picture below.
Step 2
Use a plastic blade to separate the laptop case. Do not try to speed up the process, as there are many small buckles that need to be separated, so be sure to use the tool slowly and multiple times with moderate force to open the back cover.
Step 3
After opening the back cover, the battery is located in the lower right corner. Next, we need to use a cross screwdriver to remove the screws according to the marked position.
Step 4
Locate the battery connector on the motherboard and disconnect it with moderate force.
Step 5
After removing all the screws that hold the battery in place, simply lift the battery opposite the pin and slowly slide it out. Do not lift it at too large an angle to prevent the battery from breaking or getting damaged.
Step 6
The above steps can safely remove the battery.
