Hello! It seems like you're experiencing some issues with your HP 14-inch laptop where the LED indicator blinks white and the screen blinks when you try to power it on. This could be caused by a few different things, but here are some troubleshooting steps you can try:
1. Check the power adapter: Make sure the power adapter is securely connected to both the laptop and the power outlet. Try using a different power outlet or power adapter to see if that resolves the issue.
2. Remove the battery: If your laptop has a removable battery, try removing it and then plugging in the power adapter to see if the laptop will power on without the battery.
3. Hardware issue: It's possible that there could be a hardware issue causing the problem. If you're comfortable doing so, you can try reseating the RAM and hard drive to ensure they are properly connected.
4. BIOS reset: Try resetting the BIOS by removing the CMOS battery for a few minutes and then reinserting it. This can sometimes resolve power-related issues.
5. Professional help: If none of the above solutions work, it may be best to take your laptop to a professional technician for further diagnosis and repair.
I hope these suggestions help resolve the issue with your laptop's screen blinking and looping on startup. Let me know if you have any other questions or if you need further assistance!
