Dell Precision m4600; Intel Core i7-2820QM / 2.3 GH, 16GB RAM, 300GB HDD+120GB SSD. w7 64bit.
so ive gotten this laptop about a year ago. since the very start it had this glitchy way of of hibernating... warranty people paid no heed to this since, well, it was working, wasnt it?
symptoms: when i choose "sleep" screen goes blank. but the whole system is wide awake. can hear silent windows 'pings' when i click the keyboard. same happens on hibernate mode. i left it throughout the night like this couple of times, and thats exactly how i found it in the morning still. this would be less annoying if it could wake up from the blank screen, as of now the only way to fix it is pulling the plug and restarting. by the way, this doesnt always happen - just mostly when ive done some heavy work on it. ie, i can put it to sleep perfectly fine right after turning it on.
tried few suggested solutions to this. like, "there could be devices interfering with hibernation," "programs or drivers might be keeping it awake" - so wasnt using wacom tablet for awhile at all. or even loading photoshop. updated all the drivers and firmwares too. problem persisted.
now, im still not sure what is causing it. for awhile i thought it might be some weird process that came with shop's windows version? so i formatted C. solution to all your problems, right? wrong. exactly then i found whole bunch of new ones. windows wasnt going to instal the easy way. it wasn't enough to format only c, laptop demanded i scrap the other drive too. something about gpt partition, uefis and legacy boot up whatever - cant recall what it was exactly nor what it meant (im not much of a technical person). tried whole bunch of different bios settings anyway. to no awail. after whole day of battling there was no way around it - just i didnt format the other drive, just pulled it out of computer. great success. but hibernation issues persist.
however, during that endeavour few lines kind of caught my attention. those fancy gpt partitions or settings or whatever that came with the SSD disk have the ability to make computer sleep and wake up more swiftly. since then i was thinking - could this be the culprit? can this be fixed?
ps - SSD (samsung ssd pm810 mSATA 128gb ATA) is my main disk that has windows on it. standard HDD that they wanted gone is only for data.
