it must be extra sinister. a typical element i've got seen fail on laptops is a failure the place the A/C %. plugs into the laptop. It wears out via apply. try this rapid try. Take out the battery from the laptop and attempt to run the laptop off right this moment A/C. If it runs, you recognize that's the battery. (they do circulate as nicely). If it would not, you recognize that's the two the capacity %. or the circuit from the capacity %. to the laptop. the only thank you to attempt if that's the capacity %. in case you have a similar one. i'd circulate to appropriate purchase or something comparable that sells capacity packs. tell them, you think of the A/C %. is going, and you desire to attempt it. Run the try without the battery in returned. see in case you have an issue. i think that's the circuit that feeds the DC capacity into the battery. i've got seen this fail diverse cases. that's reason the extra cases you plug it in, and unplug it, it wears out the little wires connecting it to the capacity supply/battery circuit. the only thank you to repair that problem is a sparkling motherboard.
