I hope someone can help fix this issue I have all the family ready to string me up. The laptop will not start. I've tried most things but to no avail. Thanks in advance.
When the power on button is pressed the green light comes on, the keyboard backlights briefly flash, the fan spins up for brief instant, if I listen very closely with the back cover off I can hear the speakers hiss with noise, and (if I have reset the machine) 2 tiny red LEDs on the F1 and F4 keys flash once. The power light remains green but then nothing happens. If I turn it of I get a sharp pop sound from the speaker. When I plug in the AC adapter the power light flashes 3 times. Same results with or without power adapter.
This all came about after I had gone against my mantra of 'if it ain't broke - don't "fix" it'. I updated various drivers from the Lenovo site both manually and after selecting an automatic update. I cannot recall every item that I downloaded in the end but
To my knowledge or recollection I did not install anything to do with BIOS/UEFI.
I also ran the Samsung magician utility, found the SSD was not supported and then uninstalled it.
Towards the end of all this the computer did suspend because the battery reached 5%. But I don't think I was doing any update at the time. I had not rebooted at this point.
When I came back to finish things off the next morning I had an irate daughter and wife standing by the Thinkpad asking what I'd done.
To try to fix this I have:
All the above was advice across the forum. Am I missing something? Is this really a coincidence and its a hardware failure (of the motherboard?) or have I, and the updates, screwed the machine?
A new mother board is about half of what I paid for the machine, secondhand, 8 months ago so verging on the uneconomic.
The exact model is 20BTS0MX00 running Windows 10 - can't recall the exact version number.

I have read through this a couple of times and the only thing that seemed dangerous was suspending after an SSD firmware update but before a restart. That should be OK but even if it screwed something up, it should only screw up the drive. I never like the idea of a coincidence, but I have no other ideas. If you have an external monitor, try that. It is possible that the machine is running but the video is messed up.

Thanks for your reply Rich. I agree, I'm suspicious of coincidences.
Unfortunately I had already tried that and it didn't work. I just forgot to list it in the actions above. I attached my 4k monitor to the laptop mini display port but still nothing ;-(
If auto update did change BIOS/UEFI and that was corrupted is there anyway to fix that?
I will try creating a bootable BIOS USB - but I couldn't get it to boot to an installation USB for WSE2016 - so I don't hold out much hope.
Am I really facing a motherboard replacement? The replacement cost, even for a refurbished one is close to uneconomic. Thanks
