Einleitung

If your computer struggles to hold a charge, powers off unexpectedly, or only works when plugged in, the internal battery may need replacement. Batteries naturally degrade over time due to regular use, heat, and charge cycles. Replacing the battery can significantly improve the device’s reliability and portability.

Caution: Always power off the computer and disconnect it from any power source before beginning this repair. Failing to do so can result in electric shock or short-circuit damage.
Note: This guide involves opening the device and disconnecting internal components. Work on a clean, static-free surface and use a proper toolkit to avoid damaging delicate parts.
Reminder: As you remove screws or disconnect cables, take note of their original positions. This will make reassembly smoother and help avoid errors later.

By following this step-by-step guide, you’ll be able to replace the battery safely and bring your computer back to reliable mobile performance.

Schritt 1

Use a Torx T5 screwdriver to remove the six 4.60 mm screws on the sides of the laptop securing the bottom panel.
Keep the screws organized in a pile to make reassembly easier.

Schritt 2

Insert a plastic spudger or opening pick into the seam on the side of the laptop between the bottom panel and the chassis.
Gently slide the tool along this seam to release the internal clips.
Go slowly to avoid cracking or snapping the plastic clips.
Once the internal clips are released, lift the bottom panel off.

Schritt 3

Use a Philips #0 screwdriver to remove the five 4.60 mm Phillips #0 screws securing the battery to the chassis of the laptop.
Keep these screws in a separate pile from the bottom panel screws.

Schritt 4

The battery of the laptop is connected by a short connector cable located at the top of the battery.
Use the flat end of a spudger to lift and unclip the outer edges of the battery. You may need to use your fingers to pull the connector completely out of its socket after loosening it.
Do not pull on the battery wires—only lift from the plastic base of the laptop using a spudger.
To reconnect the connector cable after repair, carefully position the connector over its socket above the battery and press straight down—the connector should snap into place without much force. If you're having trouble, the connector is most likely misaligned. Reposition it and try again.
Lift the battery out of the laptop.
