What if your LENOVO ThinkPad Yoga 11e 3rd Gen does not return from sleep mode, and the computer does not work?

Solution: If the computer does not return from sleep mode, it might have entered sleep or hibernation mode automatically because the battery is depleted. Check the system-status indicator (illuminated ThinkPad logo).

– If the system-status indicator (illuminated ThinkPad logo) blinks slowly, your computer is in sleep mode.Connect the ac power adapter to the computer; then press Fn.
– If the system-status indicator (illuminated ThinkPad logo) is off, your computer is in power-off state or in hibernation mode. Connect the ac power adapter to the computer; then press the power button to resume operation.

If the system still does not return from sleep mode, your system might stop responding and you might not be able to turn off the computer. In this case, you need to reset the computer. If you have not saved your data, it might be lost. To reset the computer, press and hold the power button for four seconds or more. If the system is still not reset, remove the ac power adapter.
