Can you charge an 11 volt laptop battery with a 12 volt power supply?<|im_end|>
<|im_start|>assistant
It is generally not recommended to charge a laptop battery with a power supply that has a higher voltage than what is specified for the battery. Using a 12-volt power supply to charge an 11-volt laptop battery can potentially damage the battery or the device it powers. It's best to use a power supply with the correct voltage for your laptop battery, which is usually specified on the battery itself or in the device's manual. If you're unsure, it's best to consult with a professional or manufacturer to avoid any potential harm to your device.<|im_end|>

What are the specifications for a Lenovo Thinkpad T440, will it safely charge on 11 volts?<|im_end|>
<|im_start|>assistant
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.<|im_end|>
