Please help desperate ! Sleep issues and Shutdown issues

[ashman1970]

I though I had the sleep issues fixed but I just powered my Dell D630 on and off 10 times and every time booted to a black screen whereas before it would boot to login more then half of the time, nothing has changed to cause this that I know of. I thought I had this fixed, I'm so upset now as I use this laptop every day and can't afford to be sitting around after I turn it on to use it. Also it doesn't shut down properly and I think the issues are related, when I tell it to power down it goes through the motions but the power light and wifi light on my laptop stay on and don't see, to turn off even if I leave it over night.

 

Any ideas?
