Ok, I read this post because I was having the same problem.....took off the otter box and gave it a good blow along the top.......the top left lock works now. Holy cow! I thought this only worked with Nintendo games.

Hi to all,
Im a proud user of Blackberry 9780, OS version 6 and I had same problem with lock button that it wasnt working well.
I red many guides how to fix it and because the phone I have is almost brand new I really got a bug in my head and I can not stop thinking what it should be because when I press lock button it doesn nothing. Just turn off for a second and immediatelly lights up and lock button wasnt working at all.
So I open the phone very carefully asi I have to do and I try to change both top buttons from working phone I have for parts. The buttons looks nice and shine brass so It should be fine I think. Phone assembled but same not working.
Okay, maybe there is wrong contact to the main board with small pins.. Open again carefully and push a little more to help pns with touching main board. Assembled tohether but still not working.. Guys my head starts cook...
I stoped and I start thinking to use my original Blackberry leather pocket where the phone turn of the display but before I did it I play around with applications after the update and there was a aplication called BLACKBERRY LIGHT.
At first I thought Its a aplication for light to see some in darkness so I wanna try this app and nothing happened, only there was options Active and DEACTIVE. I try to switch few time and because nothing happened I just deinstall this aplication and you know what?????? The phone is now working as have to work. Lock button working and dimmer too...
Fu......ng application did such mess in my phone. If the application has some description all should be easier.
So its my solution how to fix not working Lock/unlock' button on Blackberry BOLD 9780 and 9700.
