Troubleshooting a Laptop that Won’t Run on Battery

Several factors could be at play if your computer only powers up when plugged in.

Battery Issues

The most common culprit is a faulty or dead battery. Over time, laptop batteries degrade and lose their ability to hold a charge. If your battery is old, it may not be able to power your laptop anymore. Try removing and re-inserting the battery to see if that solves the issue. If not, you may need to replace the battery.

Power Settings

Your computer’s power settings could also be causing the problem. Check your power plan settings and make sure that they are not set to prioritize plugged-in power over battery power. Some power-saving modes may disable the battery when plugged in, so try adjusting these settings to see if that helps.

Charging Issues

There might be a problem with your charger or the charging port. Inspect the charger and the charging port for any damage. If you see any frayed wires or bent pins, you may need to replace the charger or have the charging port repaired.

Software Problems

Occasionally, software glitches can interfere with battery function. Try updating your operating system and drivers to see if that resolves the issue. You can also try resetting the SMC (System Management Controller) on a Mac or the BIOS (Basic Input/Output System) on a PC, as these can sometimes fix power-related problems.

Hardware Malfunctions

In rare cases, a hardware malfunction could be preventing your laptop from running on battery power. This could be due to a faulty motherboard, power supply, or other internal components. If you suspect a hardware issue, it’s best to have your laptop checked by a professional technician.
