Try These Steps
***1. Perform a Hard Reset***
Disconnect charger
Hold down power button for 30 seconds
Reconnect charger and try to turn it on[br]
[br]
***2. Check RAM Modules (if accessible)***
Open the back panel
Reseat or replace RAM (take out, clean contacts, reinsert)
If you have two sticks, try starting with one at a time[br]

***3. Try Without Battery (if removable)***
Remove the battery
Plug in only the charger
Press power button[br]
[br]
***4. External Monitor Test (for display failure)***
Connect to external monitor or TV via HDMI
See if anything shows up[br]

***5. Check LED Blink Patterns or Beeps***
Some Dell laptops flash LED codes or beep to indicate hardware faults (like "2 amber, 3 white")
Count the blink/beep pattern and tell me — I can decode it for you
