Won't charge won't turn turn on, charger LED change intensity
Hello after 4month remaining unused (it was working last time it was powered off) my 5130 won’t charge/turn on anymore, the top right led never turns on the only thing that happen when i detach the charging cable from the tablet is that the charger (genuine DELL) LED lowers it’s intensity for 1sec than go back to normal intensity.
What i’ve tried:
-replacing main battery
-replacing micro USB power cord
-use the docking station to charge/turn it on
-deatach the CMOS battery for some mins
-keep power button pressed for over 30sec
-keep pressing power and volume/up down keys
It seems just dead… any suggestion?
