I'm having a frustrating issue with my Dell 7290 laptop—it randomly shuts off about once an hour. I suspect the charging port might be the culprit since it sometimes starts back up (and occasionally in diagnostic mode) if I unplug and replug the charger, then press the power button. I tried using a different charger, but that didn't solve the issue. Just to clarify, I initially used a phone charger that wasn't powerful enough for my laptop.

The fact that it boots to diagnostics is a bit concerning. Have you run the extended tests yet? Also, how's the battery looking? We've seen a lot of issues with expanding batteries in the 7000 series laptops, so it’s worth checking.
You might want to check your Power Options settings. Set it to "Never" turn off when plugged in, and you could also configure it to do nothing when the lid is closed. This might help prevent the shutdowns.
Have you checked if it’s overheating? Dust buildup can cause problems, so if you haven't already, consider taking the back off to clear out any dust. Also, you can check the Windows event viewer for system logs that might explain the shutdowns. When it turns off, does it show a ‘shutting down’ screen or just cut out abruptly?
It sounds like it could be an issue related to either heat, the battery, or power management settings. I recommend checking the CPU and GPU temperatures, updating your drivers and BIOS, and testing with the battery removed or a different charger. This could help narrow down the cause.
