1. Critical Warning Signs of a Swollen & Dangerous Battery
Modern ultra-thin laptops use Lithium-Polymer (LiPo) pouch cells. When these cells degrade due to high operating temperatures or continuous 24/7 charging, internal chemical decomposition releases combustible gases, causing the pouch to swell like a balloon.
- Trackpad Stiff, Unresponsive, or Popping Out: The battery pack sits directly underneath the trackpad. A swelling battery exerts upwards mechanical pressure, jamming the click mechanism.
- Laptop Wobbles on Flat Desks: The bottom aluminum cover bows outward, causing the rubber feet to lose contact with the tabletop.
- Sudden Shutdowns at 30% - 50% Battery: High internal cell resistance causes instant voltage collapse under moderate CPU turbo boosts.
- "Service Recommended" Warnings: Battery health capacity has dropped below 80% of original design capacity.

5. Frequently Asked Questions: Laptop Batteries in Vietnam
Q: Should I keep my laptop plugged into the charger constantly while working?
A: Modern laptops have smart charge controllers that switch to direct AC power once full. However, heat degrades batteries; use built-in 80% charge limit features (such as AlDente on macOS or Dell Power Manager) to double your battery lifespan.
Q: How long is the warranty on replacement batteries at VietITPro?
A: We provide a comprehensive 6 to 12-month direct 1-to-1 replacement warranty on all OEM battery models. If capacity drops unexpectedly or the pack triggers a system error, we exchange it immediately.
