G443 - Awakens from sleep into BIOS cycle/loop

Hi - Entirely new to forum, and would appreciate any thoughts/input. I purchased a G443 in the Fall of 2023. Within a few days, I noticed that it would often awaken from sleep and go into the BIOS, but if I exited the BIOS, it would go right back into the BIOS in an endless loop. I could break out of the cycle by powering off and then powering back on. I brought it back to the store, and they didn't bother troubleshooting it and simply replaced it. Within 2 weeks, the exact same thing started happening with the 2nd system. At this point, I was thinking it was something I had done, but I hadn't customized or changed any settings (I'm not that tech-savvy). I interacted with several tech support folks at the store, one of whom said he was aware of this issue, but nobody else had heard of it. I took a chance and let them replace it again (3rd system). It has been find for the past 9 months, but starting 2 weeks ago, same problem. I've started digging around the power schemes and system reports, but haven't come across an obvious issue, apart from the fact that it's clearly related to sleep. I'm under warranty but at this point would rather try to figure out why it's happening instead of being offered a 4th system. Appreciate any suggestions from folks on the forum!
