While using a PC card, if you press Fn + F12 or select "System Hibernation" on PowerPanel to put the PC in system hibernation mode (Save To Disk), the PC goes into system suspend mode.

Sony has been investigating this problem. While using a PC card, if you select "System Hibernation" (Save To Disk), the PC goes into system suspend mode. To go into system hibernation mode, remove the PC card first.

[Remarks]
This symptom may occur especially on PCGA-CD51 when PCG-Z505xx or PCG-N505xx works on battery since PCGA-CD51 does not have an AC adapter.
If you leave the PC with PCGA-CD51 connected during the battery operation, the power management function works when the battery becomes weak and the PC tries to go into system hibernation mode. However, the PC goes into suspend mode, and then it is turned off. Sony recommends disconnecting PCGA-CD51 during the battery operation.

If the PC does not go into system hibernation if you remove a PC card, check if the PC has the "save2dsk.bin" file. The PC does not go into system hibernation mode if the file contains an error.
