How do you think clocks work ? If a clock is running slow , does that mean its from a slower earth ? <| sep |> So yeah it doesnt have a grounded power port . One thats a shock hazard and you run the risk of potentially ruining your motherboard should it ever decide to ground out through somewhere else in the computer . Two , you said you bought it refurbished from someone you ' ve said lied to you and seemingly tried it himself im guessing nonlicensed so you don ' t know the extent of what else has been done to it . I would assume they did a shitty job rebuilding it with a refurbished motherboard if your battery isn ' t able to charge and you ' re having open electrical circuit problems . I seriously doubt you can fix that yourself , you can probably pay someone who knows what they ' re doing an outrageous amount of money to fix it or get a new laptop .
