🔋 Laptop Battery Not Holding a Charge? Here’s When to Replace It and Why It Matters

Written By m byrne

Is your laptop shutting off unexpectedly? Only running for 20 minutes unplugged? Or refusing to charge at all? These are all signs your laptop battery needs replacing — and fast.

At Gary’s Computer Repair Service, we provide fast, affordable laptop battery replacement for all major brands — helping customers across Dublin keep their devices mobile and reliable.

🔍 Signs You Need a New Laptop Battery

1️⃣ Drains Too Fast
A full charge used to last hours — now it barely lasts 30 minutes. That’s a sign your battery’s capacity is wearing out.

2️⃣ Battery Not Charging
If your laptop says “plugged in, not charging,” or doesn’t respond at all when connected to power, your battery may be dead.

3️⃣ Laptop Shuts Off When Unplugged
If your device turns off immediately after removing the charger, the battery is no longer functioning.

4️⃣ Overheating or Swollen Battery
If you notice excessive heat, bulging under the keyboard, or warping near the trackpad — replace your battery immediately.

5️⃣ Battery Warning Message
Your laptop might display a “replace battery” or “battery health low” notification in Windows, macOS, or Linux.
