my X240 does not wake up from sleep/deep sleep.
The machine is connected to the power adapter, battery inserted. Once it falls into sleep for more than ~ 20min, it does not react to key trokes mouse moves or power button.
Instead, I need to unplug the power supply and press the reset button. Sometimes I even need to remove the battery otherwise the reset button would not work
All drivers are up to date, BIOS as well.
Have seen similar posts up here but also elsewhere - offered solutions ranged from BIOS update, driver roll backs till even mother board replacements.
Have not been in touch with a Lenovo service center yet, hope to resolve things by myself.
Is there any straight forward solution? Thx
