Here is a suggested list of steps to take when your laptop’s battery is not holding a charge after being in sleep mode:

1. Check Display Settings: Make sure that the display is not set to stay on until manually turned off.
2. Check Battery Status: Ensure that the battery is fully charged and can hold at least a few hours' worth of charge.
3. Check the Power Plan Settings: Make sure that the power settings for when the device is asleep are set to the optimal settings for power usage.
4. Update Drivers: Look for updates for your laptop's drivers, including BIOS, and system drivers. This could help your laptop's battery life.
5. Check Background Processes: Make sure that there are no programs running in the background that are needlessly using up battery power.
6. Restart Computer: Ultimately, it may be necessary to restart the computer if all else fails.
