hi,

since today i have a problem with my n900

when i close the phone a little bit to hard, it crashes....

it doesnt do the normal shutting down process, it just off in less then a second

everytime its happens i have to restart,
when i close really gently i don't have a problem...
anybody here who knows what i'm talking about an how i might be able to fix it,
please help, i don't want to send it back to finland to have it repaired
thanks in advance
