The CMOS battery compartment detached from the motherboard.
The CMOS battery holder caused damage to my old motherboard. Now I need to press F1 each time the computer starts, which is annoying, and I can't reach the BIOS. Some contact points are still exposed, so I can solder components onto them. Should I connect a capacitor or resistor across the contacts to simulate a battery presence? Or maybe I should replace the non-rechargeable laptop CMOS battery by cutting off the connector end and soldering the leads directly to the board? There might be other ideas I haven't considered.
I can't simply attach it. I'd need to solder it, but there aren't enough connections remaining.
The concept of the laptop battery appeared promising, but as an admirer, your question about the board's age comes up.
Why not just a few short wires leading to a battery compartment? It doesn’t need to be attractive, just needs to work. You could always use double-sided tape to secure the holder in place. There are many different designs for CR2032 battery holders. In fact, there are numerous tabbed battery options, which tend to last longer than what you might require right now.
Approximately 15 years ago it became common. My main system isn’t that setup. I’ve got a lot of soldering skills, so I’m confident it won’t be a problem. I could try this if it saves money compared to the new CR2032 holder. Yet, I might just purchase a holder with some short wires to avoid clipping and rewiring the battery when it fails.
