X240 will not wake from sleep

Hello,

 

I am using an X240 with the following specs:

 

Processor:  i5-4300 CPU @ 1.90 GHz 2.50 GHz

RAM: 8.0 GB

System: 64 bit, Windows 7

No external monitors

 

When my computer lid is closed and it automatically sleeps it is not possible to wake it again when I open the lid. I will move the mouse (both the external and the built in), touch the keys, and even push the power button and it will not wake up. The power button light remains solid.

 

The only way I have figured out how to wake it up is if I plug in a VGA cable that is connected to an external monitor or projector.


Does anyone know how to fix this?

Re: X240 will not wake from sleep

First step is to look in the event log to se if a device is throwing a message about a problem entering the sleep state.

I have not found any events logged relating to the sleep state.

Re: X240 will not wake from sleep

When it is sleeping, the power button light should pulse slowly.  Does it do that?

It does not, it is solid.
