Does the european version work in the US with their slightly different frequencies? Personally, I’m a little leery of the entire Murena thing. I get the privacy angle, but I’m more interested in the hardware.

If your bios is getting reset it’s possible your system uses a cmos battery and it is dead. It’s separate from the main battery and handles date/time/bios.

Just look for something that looks like a button battery inside your laptop. Sometimes it’s wrapped in plastic. My old Dell had it wrapped in rubber which held the wires in place and had a special connector.

Newer systems don’t have them - they just rely on the main battery. But if yours is losing time/settings you might have one with a separate battery. It’s usually a cr2032 or similar.

Facebook - I’ve found their mobile app is very large and I didn’t like the temptation to look at it all the time. I switch to using a browser in privacy/incognito mode. I log in and spend more quality time seeing what my friends and family are up to without obsessing over it.
