Customer benefits The "Safe Standby" solution patented by Fujitsu Siemens Computers once again improves the S3 powersave mode "Safe to RAM" in respect of data security. Safe Standby provides effective protection against data loss due to power failure in the standby state. [. . . ] Together with each S3 (Standby or Safe to RAM), the contents of main memory are now also written to the hard disk (in a similar way to the S4 sleep state or Safe to Disk). The system status is stored in the file "C:\SAVETO. DSK". The size of the file is identical to the size of main memory. The space required for the file ­ including an extra 34 MB buffer ­ is reserved on the hard disk. Note: The "SAVETO. DSK" file must not be changed, e. g. When the system is woken up again, it initially behaves as in the case of a normal wakeup from S3. If, however, the power supply has been interrupted in the meantime, the main memory would be empty and a normal wakeup would not be possible. Thanks to Safe Standby, the data from main memory is still present on the hard disk. Thus, if the PC is woken up after a power failure, the BIOS first copies the relevant data from the hard disk into main memory (approx. 30 seconds) in order then to initiate a normal wakeup action from S3 (approx. Apart from the acceptable time delay, the user is unaware of the preceding power failure.
