I'm having problems with hibernating on my laptop. Clean install,all updated,all ok. But my integrated webcam and one usb pen drive prevent hibernate event. Here are related part from powercfg -energy command Code: USB Suspend:USB Device not Entering Suspend The USB device did not enter the Suspend state. Processor power management may be prevented if a USB device does not enter the Suspend state when not in use. Device Name USB Mass Storage Device Host Controller ID PCI\VEN_8086&DEV_27CC Host Controller Location PCI bus 0, device 29, function 7 Device ID USB\VID_058F&PID_6387 Port Path 3 USB Suspend:USB Device not Entering Suspend The USB device did not enter the Suspend state.

Device Name USB Composite Device Host Controller ID PCI\VEN_8086&DEV_27CC Host Controller Location PCI bus 0, device 29, function 7 Device ID USB\VID_05A9&PID_2640 Port Path 8 USB pen drive is vital for boot stage,I've tryied to disable it from device manager but even disabled still appear on powercfg -energy log Same hardware configuration under XP was working fine with hibernation. Some help or ideas are welcome. P.S. In device manager is marked allow to turn off for USB devices In BIOS tryied both variants allow-disable USB to wake. In power management is disabled hybrid sleep. USB selective suspend is enabled. Multimedia sharing settings is to allow sleep.
Laptop is Dell Inspiron 9400 (E1705) I do a hardware mod,internal SATA port is switched to AHCI and used as ESATA and for OS and storage I have SATA express card with two WD Scorpio black in RAID 0. BIOS is unable to boot from express card,even more,if there are no device connected then no INT13 provided by BIOS,that was solved by that pen drive where is grub4dos just used to remap hd0 (USB pen drive) with hd1 (RAID 0 express card) and then boot from RAID. As for others who may ask how to switch to AHCI on 9400.That is possible but impossible to boot from attached disk. That model doesn't have stock webcam,but there was one free USB port of ICH7-M (used in M1710,M90,same board like 9400, for dock slot) webcam is 2MP one from Dell M1530 or M1330 I think. Right now I'm thinking with webcam could be an issue from BIOS side,since that port is unused in that model could be that is not properly configured in DSDT or BIOS doesn't setup right chipset registers. Need to check again datasheet and take a look on M1710 DSDT. But for pen drive I don't know,I just have -1 USB port,still remain 5 free. Strange is that on XP is working fine.
I find Sleep Mode works better try this: turn off hibernation completely go to command prompt (run as admin) and type in powercfg -h off and hit enter if you haven't touched Sleep Mode settings then it should still be on
Here is a big problem. Sleep was not working since expresscard mod. Laptop enter sleep state but on resuming it does in fact a cold boot. That's why I need hibernation.
Then why was working with XP ? (hibernation) Now looking at schematic I see laptop can put express card into standby. Express card have this power capabilities Code: Current power state: D0 Power capabilities: 0000000F PDCAP_D0_SUPPORTED PDCAP_D1_SUPPORTED PDCAP_D2_SUPPORTED PDCAP_D3_SUPPORTED Power state mappings: S0 -> D0 S1 -> Unspecified S2 -> Unspecified S3 -> D3 S4 -> D3 S5 -> D3 PCI Express port where is connected have this Code: Current power state: D0 Power capabilities: 00000089 PDCAP_D0_SUPPORTED PDCAP_D3_SUPPORTED PDCAP_WAKE_FROM_D3_SUPPORTED Power state mappings: S0 -> D0 S1 -> Unspecified S2 -> Unspecified S3 -> D3 S4 -> D3 S5 -> D3 But I think card is powered only from RUN voltage and doesn't use auxiliar power from SUSPEND power source. Need to chect that and go this way,maybe I can switch card to required power state and keep it powered from auxiliar power. Anyway thanks for help and advices.
