My Windows 11 laptop's original 65W charger was stolen, so I replaced it with a 110W charger and cable from another manufacturer. When I plugged it in, the laptop unexpectedly booted to the BitLocker recovery screen. The device is recovered and working now; I'm trying to understand what caused it and whether changing chargers can trigger this in the future. Could the different charger have changed something significant, or was this likely a coincidence involving hardware, firmware, or a Windows update?

The most likely explanation is coincidence rather than the wattage or brand of the replacement charger. A faulty adapter could theoretically cause a boot or power error, but it would not normally alter BitLocker settings. Make sure you have a saved copy of the BitLocker recovery key, and if this happens again, check for recent BIOS, firmware, TPM, Secure Boot, and Windows update changes.
A different charger should not trigger BitLocker. Laptops are designed to switch between chargers, docks, power banks, and other compatible USB-C or DC power sources. If the charger cannot provide enough power, the usual result is a warning, slow charging, or reduced performance—not a BitLocker recovery prompt.
BitLocker recovery is usually related to a change in the boot environment, such as a BIOS or UEFI reset/update, Secure Boot or TPM changes, boot-order changes, firmware issues, or occasionally a problematic Windows or driver update. A complete battery drain or a firmware problem could also make the timing appear connected to replacing the charger, but the charger itself is very unlikely to be the cause.
That makes sense. I had installed several updates recently, so I’ll check the update and system logs to see whether something finished installing around the time this happened.
