Hi I’m have a 20 year old laptop and every time I turn it on it has reset the clock and date to 2001 or whatever and I have to set it again before I can do anything. I haven’t used it that often in recent years. Is there some part i could replace to get this working.
Also in general, is there other maintenance I should do to keep it working?
Adding a note to a note, if there is corrosion, the battery is probably leaky and spilling its blood everywhere.
Corrosion is the byproduct of a chemical reaction. That reaction has probably consumed minor (/s) things like PCB traces and component pins so the need for a thorough inspection shouldn’t be underrated.
