Can you charge an 11 volt laptop battery with a 12 volt power supply?

You should check the computer battery specifications, sometimes there is a chance of that being feasible, however, I wouldn't try it if the computer contains valuable information

What are the specifications for a Lenovo Thinkpad T440, will it safely charge on 11 volts?
user
The specifications for the Lenovo ThinkPad T440 state that the laptop requires an input voltage of 20V and an input current of 3.25A for charging the battery. An 11V power supply would not be compatible with the specifications, and I would not recommend using an 11V power supply to charge the battery. Doing so could cause damage to the battery or the laptop and may also pose a safety risk. It is always best to use a power supply that is specifically designed for your laptop and meets the specifications listed in the manual or on the manufacturer's website.
