Anna Nagar professionals and students often notice a proud trackpad before anything else — the click feels mushy, the palm rest sits uneven, or the MacBook no longer closes flush. That is usually a swollen battery pressing up from below, not a broken trackpad mechanism.
Do not keep using or charging the machine. Swelling is a safety issue. Power it off, leave it in a cool place, and bring it to our Mount Road centre (Anjuman Shopping Arcade) for a safe pack replacement.
Signs your MacBook battery is swelling
- Trackpad sits higher than the surrounding aluminium.
- Bottom case bulges or screws will not seat evenly.
- MacBook rocks on a flat desk.
- Unexpected shutdowns with “Service Battery” in macOS.
- Chemical smell or hissing (rare — power off immediately).
What not to do
- Do not puncture, flatten, or microwave the battery.
- Do not keep charging overnight hoping capacity returns.
- Do not force the lid closed if the pack has already lifted the trackpad — that can crack the glass.
- Rice and hairdryers do nothing for swelling. They waste time.

Frequently asked questions
How do I know if my MacBook battery is swollen?
The trackpad sits higher than the palm rest, the chassis bows, or the bottom case will not sit flat. Sometimes you smell a chemical odour. Power down and stop charging — do not puncture the pack.
Is a swollen MacBook battery dangerous?
Yes. Swollen lithium cells can rupture if crushed or charged further. Bring the Mac powered off. We remove the pack safely at the bench.
How long does battery replacement take for Anna Nagar customers?
Many Air and Pro batteries finish the same day when the part is in stock. Anna Nagar to Mount Road is typically 20–30 minutes. Book online or WhatsApp a side-profile photo first.
Will I lose my data?
Battery replacement does not erase the SSD. We still recommend a Time Machine or cloud backup before any teardown.
