[QUOTE="fourears, post: 803825, member: 86970"] i'm experiencing pretty much the exact same problem. my problem came about when disconnecting from an external display. ihad a dvi output, a usb input, an optical audio output,the power cable and a bluetooth keyboard connected. itook out the connections and opened the laptop to be met with ablank screen, this problem sometimes occurred so i was used to doing a hard reset to resolve the issue. on doing so on this occassion iam met with ablack screen and the standby light remains constantly lit. it is lit very dimly when the screenis open and full brightness when the screen is closed. ihave performed both the smc reset and the pram reset but the problem persists. something curious i have noticed similar to yourself the laptop remains partially functional, it still outputs sound when erroneous keys are pressed etc. the odd thing is though is that it only outputs through the optical connection i had connected before the problem started. if itake out the optical speaker cable sound isnt produced through the inbuilt speakers. if anyone can help it would be greatly appreciated, apologies for any spelling or grammer errors as im typing this out letter by letter on my playstation3 [/QUOTE]
