Safety Issue: W540 Does Not Reliably Sleep

My W540 does not reliably sleep, and does not reliably stay asleep. Several times, I have found my laptop on while inside a confined bag.

 

When a notebook lid is closed, it should be off period!

 

I feel that this is a serious safety and reliability issue.

 

Please fix this.

Look in the event viewer to see if a device is failing to sleep.

Hello,

 

It might be helpful to know the operating system(s) under which this occurs.

 

Regards,

Re: Safety Issue: W540 Does Not Reliably Sleep

This happens under Windows 10. It seems to happen more if you put the notebook asleep, without waiting a minute or two.

 

Nothing should keep the notebook from sleeping, nor wake it from sleep.

 

Intel processor may not shut down until 100c, which is likely well out of the safe operating tempature for the lithium battery in a running notebook.

 

These notebook computers may go inside the luggage compartment an airliner with hundreds of lives at stake.

Reworking the UEFI/Bios to make sure the laptop sleeps and stays asleep will help protect human lives.

 

...and processor logevity as well.

My cmputer must either not have slept or woke while in the bag, which was inside a car trunk, near 12 gallons of gasoline.

 

Please fix this!

Re: Safety Issue: W540 Does Not Reliably Sleep

I am still having problems with making sure the computer sleeps.

I found it on in my laptop bag the other day.

I would send it in for repair, but I suspect that it is a firmware issue.
