laptop wont charge or power on. power polarity issue?
laptop not used for 6 mo to a year. cant find power adapter ordered new one. used universal adapter plugged into car lighter socket did not notice any charging lights come on or any sounds smells etc but realized that I may have reversed the polarity on the charger tip.
so until I receive power adapter have no way to charge battery or run computer without battery because the universal power is not charging or powering laptop. so not sure new power adapter will work either.
is it possible that by reversing the polarity and pushing the power on button that I damaged the power system and if so what is the most likely damage and is it repairable by me? and regardless of the battery possibly being unchargeable shouldn't lights indicating charging or connected to power be coming on.
I have read elsewhere about similar problems of not powering on and resetting the laptop but those questions and answers did not include someone reversing the polarity on the power adapter.
