Why is my computer going to sleep/ standby mode?
Tricky question because of the can and can’t – however try adjusting the power settings by clicking start>control panel>power options> and under power scheme, you can set your monitor, hard disk etc to remain on permanently or turn them off after 15 or 30 minutes. Please bear in mind you can do more changes in this particular area. If you are unsure just do one change at a time a make a note of it to see how your computer will behave.
