Board clock check
What they doIf 0271 returns after every shutdown, the authorized provider checks the circuit that keeps date and time on the board.
They must show youthe message repeating after setting the date.
In writingthe diagnosis and the replaced part with its reference.
Test after repair
What they doAfter the repair, the technician sets the date, shuts the laptop down and checks the message does not return.
They must show youa startup without 0271 after a full shutdown.
In writingthe test performed and the warranty.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.

What it means
In the ThinkPad X1 Carbon 13th Gen user guide, message 0271 is "Check Date and Time settings": the date or the time is not set in the computer. Lenovo's solution is to enter the UEFI BIOS menu and set the date and time. The BIOS clock is what the laptop uses before Windows loads. If the warning appears once and goes away after setting it, it does not indicate a fault; if it returns after every shutdown, Lenovo should check the cause.
