Control button locked. when I turn ooff PC the sleep light will not turn off.
Typically, the computer is defaulted to stay turned off after an electrical outage. To start the computer from scratch again, hold the power button in for several seconds. If it powers off, wait a minute, then hold the button in again to start it. When the screen comes up that says it didn't shut down properly, choose Safe Mode without networking. It will look like it is hanging on several files, normal, let it go. The screen & icons will be large because it is in default VGA mode. Once it stops loading, go to the Start Button & choose Restart. Things will return to your chosen default settings and most things will work again providing you have an EMI/RFI Surge Protector power strip that everything was plugged into. I have had several fail after a power surge, they are supposed to. Some have insurance should you have electrical damage after a power surge that got beyond the strip. Ultimately, $15-$50 is cheaper than your PC &/or monitors damaged by not having one, they are designed to be the Sacrificial Lamb & be the cheap breaking point.
As an added note, people confuse Sleep Mode with Hibernate Mode. Sleep mode means anything you are working on gets suspended into your available memory while it goes into Power Saving mode. On a power loss, all will be lost, save regularly if you use this mode.
Hibernate uses a space on your hard drive to write the information. Power loss, nothing is lost and on waking up or powering back on, your data will still be where you left off, usually intact. To restore from either mode without electrical loss, hit the ESC key. Exceptions will occur if you use Hibernate mode but only have a power strip for your multiple plugs. A power surge can still damage your computer because it wasn't blocked by the EMI/RFI power strip.
How do you know which one you have ? If you only have an On/Off power switch, you have an unprotected power strip. If you have a button on the side of that switch, known as a Reset Switch, you have a protecting one. Even if the Reset Button doesn't restore the power strip, it gave it's blife to protect your computer equipment. Cheap insurance.
