G3 3579 Powers off

If your Dell G3 3579 laptop is turning off unexpectedly, especially when unplugged or while running, it could be due to a few potential issues. These include a faulty power supply, a misbehaving battery, or software glitches. 
Here's a breakdown of troubleshooting steps:
1. Check the Power Supply:
Test with a different power adapter:
.
If you have a spare charger, try using it. This will help determine if the power adapter itself is faulty.
Check the power adapter cable:
.
Ensure the cable is securely connected to both the laptop and the power adapter. A loose or damaged cable can cause intermittent power issues. 
2. Evaluate the Battery:
Check battery status:
.
Look for any blinking amber or white patterns on the battery charge indicator LED. This could indicate a problem with the battery or the charging circuitry. 
Run a battery diagnostic:
.
Use the Dell SupportAssist app to run a battery diagnostic. This will test the battery's health and capacity. 
Replace the battery:
.
If the battery diagnostic indicates a problem, or if the battery is old and worn out, consider replacing it. 
3. Investigate Software Issues:
Update drivers and BIOS:
.
Ensure your drivers and BIOS are up to date. Use the Dell update utility to update these. 
Check for power management settings:
.
Make sure your power plan settings are not configured to shut down the laptop prematurely. 
Address software glitches:
.
If you suspect a software issue, try performing a hard reset by holding the power button for 15-20 seconds to drain residual power, then restart.
