The hotel's uninterruptible power outlet is dead.

If the hotel's uninterruptible power outlet is dead, you can consider the following methods to solve this problem:

1. Check whether the socket is turned off: Some hotels may turn off the power of the socket to avoid unnecessary energy consumption. So, you can check whether the power of the socket is off first.

2. Replace the socket: If the socket is not turned off, but there is still no electricity, then you may need to replace the socket. You can consult hotel service personnel or electricians for specific replacement methods.

3. Check whether the line is unobstructed: If there is nothing wrong with the socket, it may be that the line is faulty. You can check whether the lines are clear or whether there are damaged wires.

4. Contact the hotel service personnel: If it cannot be solved, you can contact the hotel service personnel or electrician for help.
