🔋 Asus Zenbook Battery Not Charging or Draining Too Fast? Here’s What’s Going On

Written By m byrne

Asus Zenbooks are known for their sleek design and all-day battery life — but if your Zenbook battery isn’t performing like it used to, you’re not alone. Over time, even high-quality batteries lose their capacity. Whether your Zenbook is not charging, shutting off suddenly, or only lasts an hour, it’s likely time for a battery service.

At Gary’s Computer Repair Service, we help Asus Zenbook users across Dublin diagnose, replace, and optimize their batteries — so they can stay mobile and productive without being stuck to a charger.

🔍 Common Asus Zenbook Battery Issues

1️⃣ Laptop Only Works When Plugged In
If your Zenbook shuts off the moment it’s unplugged, the battery may be dead or not detected.

2️⃣ “Plugged In, Not Charging” Error
A common Asus issue — often caused by a faulty charging IC, battery controller, or outdated power management driver.

3️⃣ Fast Battery Drain
Battery used to last 8+ hours, now it’s under 2? Cells may be degraded or background processes are draining power.

4️⃣ Battery Not Detected by BIOS or Windows
This could be a sign of a firmware bug, hardware fault, or disconnected battery cable.

5️⃣ Overheating or Swollen Battery
Swelling or excessive heat near the keyboard or touchpad? Replace the battery immediately — it’s a safety risk.
