Charging Dallas Realtime clock

[Roman78]

I bought an Hyundai Super LT 3 laptop. Unfortunately it's not working, in the sense that it gives an error message "CMOS battery empty". That wouldn#t be a problem if it would keep the BIOS settings after an soft reboot, but after each soft reboot all the settings are gone. So i opened the laptop to search the battery and it's not an 3032 or something like that. It's an Dallas Real time clock. Now the question, is it possible to charge those so far that it will keep the bios?

Or does someone know an store were to buy one of those? New one's of course...

I used to replace these in PC's (back in the day). There is a home made hack you can do to turn this into a CR32 batter holder. Google it will get the result.

Yes, it's one of those. I'll will google it

I still have some of those in stock. Not sure if they would still work but I do have some.
