Windows booting issue - what exactly does the reset switch do on the X1 carbon?

My X1 carbon gen6 consistently will not boot into Windows 10 after a shut down. A soft restart is OK, as is resume from sleep (but not always...) But 100% of the time if I do a power on it either goes into the Windows boot manager screen, or hangs at the Lenovo logo. The NVMe drive is invisible. If I use the reset button however, it boots OK every time.

 

So what I'd like to know is what exactly is the reset button doing? I'm looking to see if I can narrow down what the problem may be. I've done all the usual stuff - ensuring firmware and drivers are at the latest levels, including a fresh re-installation of Windows 10, but the problem persists. What is it about the reset button that fixes whatever is going on here?

 

Thanks!

Hi @TDR001!

 

Welcome to Lenovo Community Forums.

 

When did the issue start? Did you notice any system updates prior to the issue?

 

Emergency-reset hole helps if the computer stops responding and you cannot turn it off by pressing the power button. You may try updating the BIOS version directly from our support website and observe if you'll see any changes.

 

Regards,

If you hold down Shift key while selecting Shutdown from start menu, does problem happen after that?

Re: Windows booting issue - what exactly does the reset switch do on the X1 carbon?

Now that normal programming has resumed with this community:

 

Shift + shutdown = inconclusive. Sometimes it allows boot, a couple of times it didnt. However, some updates since then:


1) Lenovo vantage software said there were no updates despite a BIOS update issued just after my original post. So I've removed this software as clearly it's a bit of rubbish and I can't rely on it for critical updates and will do manually. And yes, I reinstalled it and it still couldn't see the BIOS update plus another update...I can't recall now, but I think it was the audio software.

 

2) I had a Logitech mouse dongle attached which needed a firmware update, plus, I can't be sure, but Windows may be thinking it's a boot device despite the fact that USB boot is down the boot order past Windows Boot Manager and the NVMe drive. This could be a red herring however as I try to eliminate options

 

3) Reset switch via pinhole also failed me a couple of times since posting to this thread but I think I didn't hold the paper clip in long enough so inconclusive on that one...

 

4) A complete reload of Windows didn't fix the problem as per my original post so that should have knocked out most outdated driver issues especially as I no longer use the Logitech dongle

 

I'm starting to suspect the NVMe drive - Samsung EVO Plus 970 500GB - doesn't play nice with the X1 Carbon and manifests as an intermittent fault. Drive diagnostics come up clean and firmware is up to date. I've also switched between the MS NVMe driver and Samsung's ...doesn't seem to make a difference.

 

Plus I really want to know what that reset button does! I read elsewhere that it may temporarily disconnect the internal battery, but I  tried this originally via BIOS settings and it didn't make a difference so I'm thinking it's doing more than that. Hoping there is a Lenovo engineer watching that can tell me exactly what is happening with the reset button to help me to understand where the problem may lie.

 

thanks
