VAIO® Notebook User Guide
❑When the internal backup battery is low on power, it may not be able to boot your system properly. You can correct this situation as follows:
❑Plug in the AC adapter and allow the computer to charge for one hour while the power is on. Do not use the computer during this time.
❑After one hour, turn the power off and then on again. To charge the internal backup battery fully, keep the AC adapter connected for more than 24 hours after turning the power on. You can use your computer while charging the battery.
❑The operating system may become unstable if a lower power state such as system hibernation is initiated and then changed before the operating system completely enters the lower power state. To restore the notebook to its normal operating stability, close all open applications, and slide the power switch forward and hold it there for four seconds or more to completely shut down the notebook.
