M900 won't boot in the morning, though the BIOS is set to do so

2016-08-01, 12:40 PM

Hi,

 

I have a few dozen Lenovo M900s that are configured in the BIOS to boot each morning at 8:00 a.m. except they don't do it. The BIOS clock is correct. CSM is enabled as these machines are still running Windows 7. What else can I try. TVSU doesn't offer a new BIOS update for that model.

 

Thanks

You wrote "boot in the morning", that implies they are shut down at end of the day before.   Are they shut down (powered off) or put to sleep or hibernated?

They are shut down by a GPO-based scheduled task.

This evening, can you sleep a couple and hibinate another couple and see if they wake at the set time?

Sure. I can try. Sleep and hibernate are disabled in the operating system image.

Turns out that it was a BIOS update that fixed the issue. BIOS-54, according to Lenovo support. That fixed the issue for me.

Hi, just wondering if you had a similar boot up problem on the 1st of September (last Thursday)? I discovered that my M600's won't 'Start up on alarm' on the first day of any month.

 

I started a new thread here:

Thanks

Rich

Hi,

 

I just had this issue today, 12/1/16. I tried a new BIOS update, released on 11/8/16, but am not confident that addresses the issue. Thanks!
