I want to know the answer to the following question:
On what laptops are the sleep-and-charge marked with a non-standard symbol?
All the background I'm provided with is that "On Acer Inc. and Packard Bell laptops, sleep-and-charge USB ports are marked with a non-standard symbol (the letters USB over a drawing of a battery); the feature is simply called Power-off USB.". Is that enough to answer the question?
Answer: yes
