2 amber lights and 1 white light

Hi Community,

I am reaching out to seek your expertise regarding a recurring issue with my Dell laptop. Recently, I have noticed the following problems:

• When I attempt to power on the laptop, the caps lock button lights up, and the indicator light near the charging port blinks amber twice and then white once.
• The laptop display remains off, and while the fans initially start up, they quickly turn off within about 10 seconds.
• Additionally, a long press on the power button only restarts the system rather than fully powering it down.

I have attempted some troubleshooting steps, including a power drain, removing external devices, and even reseating the RAM, but unfortunately, the issue persists.

Could you please advise on any further steps I could try, or would you recommend a diagnostic inspection? If there are any costs involved, I would appreciate details on the fees and any relevant service options.

Laptop Details : Inspiron 3593 DR9XR53

Fun fact is that: After 2 days from this issue, my laptop boot in to BIOS and asked for time setting and I saved to default. Then after few restarts, the laptop gone to never ending bootloop (JUST restarting, keyboard backlight on and no Dell logo!!). I just need to wait until all power is 0% and dead  to make the close the lid and pack it up.

Any insight will be helpful.
