I've been having some problems with my Inspiron 15R N5110. Whenever I close the lid to put it into sleep mode, the screen turns off but the fan kicks in and it doesn't go to sleep. When I open the lid again, the screen is still off and the power button light and 'screen off' button light are illuminated. Absolutely nothing wakes it from this state except a hard reset. This problem has been happening for a while, but it was so infrequent that it never bothered me, now it's suddenly happening everytime I close the lid or select sleep/hibernate from the start menu. (Conveniently, the warranty ran out a few weeks ago..). It's also no longer shutting down or restarting, the windows 'shutting down' screen displays for a few seconds, then the screen turns off and the fan kicks in. Again, the only way to turn it off is to hold the power button.
I've tried everything under the sun to fix this. Updated every driver, updated BIOS, played around with and changed every power option I can find, ran every diagnostic test, tried a clean boot and booting safe mode (the problem persists in both cases). I've tried a system restore, but because the system won't shut down, system restore never completes, not even in safe mode. The only option left (besides throwing the damn thing out the window) is to reinstall windows 7, but I'm reluctant to do that if it isn't going to fix my problem. Anyone know what's going on and if there's a way to fix it? And if it is a hardware issue, what options have I got with Dell since I'm out of warranty?
I regret that you’re facing this problem with the system. I also appreciate that you have performed lot of steps to resolve this issue but only way we can identify whether its software or hardware issue by reinstalling the windows 7 operating system. Also help me understand if there were any error messages when you ran the diagnostics.
Let me know if you need any help regarding the reinstalling the operating system.

Just reinstalled Windows and the problem is still there, does this mean it's hardware?
Since you have mentioned that the problem persists after the operating system reinstallation, this seems to be an issue with the hardware (graphics card). However, try running the hardware diagnostics Start tapping the F12 key a few times during startup until you see the ‘One Time Boot Menu’ appear.
At the one time boot menu, press the down arrow key to highlight ‘Diagnostic’, and then press Enter to begin the hardware diagnostics.
If the test fails, please make a note of any error codes listed. You can also refer to the link below.
Let us know about the progress.
Just ran the diagnostic test, it didn't give me any error codes, it just said that all tests passed

Unfortunately it hasn't made a difference
Never mind, I fixed the problem myself by taking the laptop apart and replacing the CMOS battery. Thanks for your help though!
