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?
Thanks.
just adding a note to this, not trying to steal the previous answer 🙂
try googling your laptop model and CMOS battery for images so you know what and where to look if you want to try replacing it. Some require dismantling of almost the entire laptop to find, so researching is recommended if you are not experienced with this type of work. There are also guides and manuals online on how to change it on some models.
Good luck! 🙂
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.
