Mining on ethermine was easy to set up and run, but after my computer goes to sleep to save power, the mining program stops, when I mine on nice has it runs on the background while the computer sleeps, how can I keep mining ethereum when the computer goes to sleep?
Are you having Windows 10 os. If yes please follow the below instructions you need to follow to change it.
Choose when to turn off the display during periods of inactivity.
Open Power Options by clicking the Start button, clicking Control Panel, clicking System and Security, and then clicking Power Options.
Under the plan that you want to change, click Change plan settings.
On the Change settings for the plan page, choose the display and sleep settings that you want to use when your computer is running on battery (if applicable) and when it's plugged in.
For more options, click “Change advanced power settings.”
When you’re done click OK.
When I was new to mining I have the same thought whether it will be mining for complete day or sleep whenever the computer sleeps.
If possible download Hive OS and flash it on your drive or flash stick to start mining uninterruptedly.
