Charger or Battery? Quick Diagnosis

Worked Example: HP Laptop Stuck at 0%

An HP EliteBook works on the charger but shows "plugged in, not charging" and dies as soon as it is unplugged. Another charger of the right wattage gives the same result. The Windows battery report (powercfg /batteryreport) shows the full-charge capacity is under 20% of the design capacity. Diagnosis: the battery is worn out. A replacement battery for the exact model fixes it; the charger was fine.

How to Run a Battery Report on Windows

Open Command Prompt, type powercfg /batteryreport and press Enter. Open the HTML file it creates and compare Design capacity with Full charge capacity. Below about 50% means much shorter battery life.

Common Mistakes to Avoid

• Using a lower-watt charger.
• Keeping a swollen battery.
• Cheap chargers without protection.
• Ignoring a loose port until the board is damaged.
