Hi, if I remove the power adapter for more than an hour and plug it back, the laptop takes for that 2 days to POWER ON I left it in a quite humide environment POWER OFF for 3 months, mold accumulated on the Keyboard. But when powered ON it works fine. I have to leave the adapter plugged to the mains and plug to the laptop. Thanks guiding me which component is defective requires replacement. Alain Mise à jour (15/07/2017) the laptop worked on adapter connected on mains without battery before this happened.
Defective battery I think.
