If I put my laptop into hibernate mode will it still need to be charging or can it be left unplugged?

A hibernating laptop uses only a tiny amount of power, in most cases only slightly more than full Shutdown mode, so assuming your laptop's battery is in good condition, and fully charged, it could remain safely in that state for weeks, or months, depending on the battery's

Even if the battery were to become completely discharged your data would still be safe as it is stored on the hard drive, and once power is restored the laptop will boot up (start up) as normal.
