![]() Hi.
Was the battery purchased from a reliable source? The details seem to hint there is something is wrong with the logic board. Post the full markings on the batteries. Maybe the batteries are not compatible with this unit ? Did the original battery ever work with this computer? What is the history? Any liquid damage? Do you have test equipment like tools, soldering iron, multimeter? |

![]() "original", "new" and "Aliexpress" never go together very well.
