I cleaned my dell inspiron15 3576 motherboard using 70% isopropyl alcohol and after 1hour tried to switch it on and saw my caps lock light is continuosly on for a minute while no other response from the system. I tried everything replacing ram slots,removing each device from laptop,removing cmos battery,pressing powerbutton for 30s and when i plug my charger i noticed the battery is not showing charging light, plus always the same thing caps lock light is on for some time.
