Hi everyone, I'll tell you a story. I'll start from the very beginning as it was. My battery broke (swollen) and I pulled it out of the laptop. After that, after each shutdown from the outlet and turn on back the next day, my bios is constantly reset to factory settings with a cmos error 502 (I don't remember exactly). I thought there was a problem with the cmos battery and wanted to reinstall it. After disassembling the laptop, I did not see any cmos battery, nor even a place for it. To be honest, I was a little shocked. I even downloaded the official disassembly manual for my laptop and it says the battery should be in place, circled in red. How to work now? It annoys me after each turn on the computer to climb into the BIOS and return the settings to their place.
