1.	Solve : My computer turns completely off if idle for maybe 20 minutes?
Answer» This never happened before. What would cause this to happen?Make? Model? OS? Hi Eg0Death, It's a Compaq Presario with Windows XPWhat are your power settings? Start -> CONTROL Panel -> Power Options A setting may have been CHANGED to power down the system after 20 minutes of inactivity. These are the settings: System standby: After 20 mins System HIBERNATES: After 25 mins I've never changed these settings and I've had the computer for hours and it never shut off. Would one of these settings completely shut down the computer?Hibernate saves the contents of RAM to a file on the HARD drive (hiberfil.sys, I think) and shuts down the computer. I'm not SURE why it wasn't working before. Thanks for your help. I'll change the settings.
