Precision 3530 can not turn on

Anyone who has experiences in handling this error, please help me:

dell precision 3530.
symptoms: my laptop was working normally, suddenly turned off. then i turned on, used for a while,  it turned off suddenly again.
after a few days, the power will not turn on, the screen is totally black, no phenomenon, the fan does not run. Only the power button light is on, the charging indicator light is on. And the keyboard light flashes a few times then turns off (when I tried to power on).
I have tried:
-remove back case then check and clean, visually I did not see anything unusual.
use each ram plugged into each slot 1 and 2 (my laptop have 2 rams and 2 slots). does not turn on.
-replace the cmos battery but does not turn on.
-remove the battery, unplug the power, press the power button for 30s (like on youtube). does not turn on.
the machine is in normal condition, not old.

thank you!

PS:  I have not usually used my laptop for a few months, only ~15h/month.
