Original title: problem with putting my laptop to shutdown and hibernate
when i click on shutdown button or hibernate button in start menu, system performs a log out and screen goes off and nothing else. fan are working and led light are on. i give it some hours but it didn't shutdown. in this state it woke up when touch pad or keyboard used and you face a welcome picture and log in screen. hibernating goes the same way.
only sleep and restart button work as expected.
the problem start after i install win 10 with an USB drive. first it just happened sometimes when i wanted to hibernate laptop. i did a restart and it work fine again for a while. then windows install some updates. 2 driver updates successfully finished but kb 3156421 fail to install. it just show "we couldn't finish the update" and undo it. after restart i face some internet access problem (solved by manually enabling some rules in firewall settings.) and this strange problem.
i'm try almost all suggested answers in net and they did't work. also chat with someone from Microsoft support but problem still exist.
i use ubutu along side windows and it shutdown system well so i don't think it has something to do with hardware but i write my hardware information:
laptop model: lenovo z410.
cpu: intel cor i7 4702mq
ram: 8 gig
vga: intel hd 4600 + geforce 740m 2gig
