1. Check Power Supply: Ensure the power cable is connected and the outlet is functioning. If the power button LED is off, try a different outlet or power cable.
2. Run Hardware Diagnostics:
   • Turn on the computer and repeatedly tap the F2 key until the One Time Boot Menu appears.
   • Select Diagnostics and press Enter. Follow the on-screen instructions to complete the test.
   • Note any error codes that appear.
3. Forced ePSA Method:
   • For Dell laptops, press and hold the Fn key and then press the power button to start preboot testing and launch ePSA diagnostics.
4. Clear CMOS:
   • Disconnect the power and remove the computer cover.
   • Locate the RTCRST jumper on the motherboard and short it for about five seconds to clear the CMOS.
   • Reconnect power and try to boot again.
5. Check for External Devices: Unplug all external devices (e.g., monitors, USB drives) and try booting again. Reconnect devices one at a time to identify any faulty hardware.
6. No Boot Issue: If the system passes POST but does not boot into the operating system:
   • Ensure the hard drive is functioning properly. If possible, test with a known working hard drive.
   • If the hard drive is fine, the issue may be with the operating system or software.
