Cowchip, you're referring to the regular battery, not the bios battery, right?
Well, it's not a screw, it's the bios battery.
The sound always came from the lower left corner, near the card reader.
I opened the module cover and could even move the coin cell battery with a screwdriver.
Obviously the battery is connected to the connector (only).
Hello Dell QC?
Is that normal? I'd expect it to snap in somehow.
I didn't disassemble the whole body to get to the bios battery yet. I'm too afraid to damage anything.
But still it's kind of annoying.
I guess I'll call customer support tomorrow.
