Sadly I don't have a cure for this one. It could be a setting or a damaged OS. If system restore doesn't cure it we reload the machine and retest. If the reload fails, we call Dell.
I have a Dell 5100 Notebook. If I shut it down after I use it (without closing it) or just leave it on, it works fine. If I close the notebook and then go to open it later, the screen refuses to turn on. I've noticed that when this happens the light for the caps lock comes on. This has never happened before and I don't know what the deal is. The only way I've found to fix it is to press the power button and then turn the system back on after 60 seconds. Any idea what happened??
