Hibernation problem

Hello to all,

I searched the web and the community forum here from Apple but i didn´t find a solution. First some important data of my machine. It is a MacBook Pro 13 mid 2010, 2,4Ghz, 4GBRam, OS Lion 10.7.2, Apple Care Protection Plan until 27.12.2013.

Second a little prologue. I had problems with the battery charge. It didn´t charge and the green / orange light of my MacSafe didn´t go on. So I called the Apple Support and we did an SMC Reset i think (shut down the MBP and then press and hold alt+ctrl+ shift+powerbutton for 3 seconds until the MAcSafe light changes the colour once). This resolved the charging problem and now my MBP is charging again and everything is ok.

BUUUUTTT, now there is a new problem. Until then my MBP won´t go into hybernation mode when it is plugged to the poweradapter. It won´t hibernate if I start it manually through the Apple menue, either if I close the MBP. It ONLY works well when in Battery mode without charging. I already did a PRAM reset and I don´t have any sharing active and I tried to change the hibernation mode from 3 to 0 but it didn´t work, too.

Now I don´t know what to do. I don´t hope my logicboard is broken.

Maybe someone has an idea what I could try to fix it. If not I will have to call the Apple Support again.

Thanks you all.

Mike
