T440s - beeps while putting in sleep mode (and a blank screen)

2015-10-14, 6:42 AM

Hi,

 

I have T440s with Windows 10 (64-bit) installed, after latest update from MS and Lenovo (BIOS 2.35) ntb beeps while putting in sleep mode (and a blank screen) 

 

Four cycles of four short beeps and a blank screen: System board (Security chip)

 

 Does anybody know what might be the problem and how to solve it? 

 

Thanks. 

 

Since I have installed Windows 10, there are repeatedly problems... 

 

ZK

I got same symtom..

 

My solution :

1) Go Control Panel -> Power Options ..
2) You may see the "Lenovo Power Optimized" selected.
3) I changed it to "Balance (recommended)"

Everything goes back to NORMAL.

 

Hope this helps,
Lee

I've got the same issue on a T440 with Windows 10 (64-bit) it seems that is related to the TPM not saving its state before the machine goes to sleep and failing to resume. I don't know if lenovo is aware of this issue, but i hope it's going to get fixed in the next BIOS/UEFI update; in the meantime you solve this problem by disabling the TPM chip in the BIOS/UEFI options.

Thanks. This worked for me. I called the issue in to Lenovo technical support, and the technician I spoke to knew nothing about it. After talking to colleagues, he said that turning off the TPM is the only solution at the moment. When I asked if there is another BIOS update planned to fix the issue, he said not at the moment - but try checking again in a few weeks. Rather disappointing - but more or less what I have come to expect from Lenovo.

Same issue here. Having to disable TPM really sucks, because I use it with BitLocker for drive encryption. The worse whing about this is that there is no way to flash back the old BIOS, Lenovo disabled it. So now I am stuck with a BIOS with a secruity flaw fixed but if my computer gets lost or stolen anyone can read my data because I had to disbale TPM and therefore Bitlocker.

My experience was that the problem only occured with sleep mode, not shutdown or hibernate - so if security is critical, you could potentially disable sleep mode and have your laptop hibernate when you are not using it instead. Not ideal for a laptop, I know, but it might be the lesser of two evils on a temporary basis. Come on Lenovo: let us know that you are aware of this issue and please give us an approximate timeline for a fix.

Same problem for my T440s. After closing the notebook, it is not possible to get it back working.

Hopefully there will be a fix soon!

Same problem with me - really annoying getting this error.

 

Lenovo please inform about the timing for a fix!

 

Thank you

Wondering if anyone from Lenovo is looking at this?

 

From the sounds of it, this is not really a Lenovo issue, but a Microsoft issue. Rational: It doesn't happen in WIndows 8.1 - the machine can wake up in Windows 8.1 without the issues in Windows 10.  So logical conclusion is that it is with a patch/update that MS has pushed out (in conjunction with the latest BIOS update).  Either way, Lenovo needs to work with MS to understand what they changed. 

 

Sadly, I have gone back to 8.1 on the T440s I have until this is resolved.
