Y550P not coming out of hibernation

[ukenyc]

Y550P not coming out of hibernation, running Win7-64SP1.  Recurring issue.

I often put my Y550P into hibernation mode, allowing it to completely 'power down' before shutting the lid.

When I try to wake it, I open the lid and press the power button.  The laptop powers up but the screen stays blank, I can hear HDD spin once, and then it's all quite and dark, with only power LED on.

Since I can't use GUI, I simply power down by holding the power button until "shutdown", wait a minute and then try to power up again.  Recently, it's taken me about  about 7 powering cycles to bring laptop back to life, at which time it resumes the saved pre-hibernation session.

I've read forums here and have not seen anyone with similar issue.  Can it be a power cable?  or BIOS?  Any support is much appreciated.

possible wireless adapter issue. un-check "save power option" in device manager > wireless adapter > options

in Power Management for Intel (R) WiFi Link 5300 AGN I unchecked "Allow the computer to turn off this device to save power"

I will post a comment in a few hours, after several hibernation/waking cycles to check the solution's effectiveness.

Thank you.

any other possible solutions are welcome.

one of the windows update causes hibernation issue.
if you remember the time when the issue started to persist, use windows restore and cancel windows updates.

I have not thought of OS itself causing a problem.  Found some articles on MSKB but need to find one with solution for me.  I mark as solved here, whenever I find a specific article I will add to the thread.
