I got my first Blue Screen of Death on my two-year-old Lenovo P73 desktop replacement laptop. When the machine rebooted, the sound mute indicator on the keyboard was on. I tried to turn it off with the key, but nothing happened. I tried to turn the sound on with the sound icon on the taskbar, but it said “No speakers or headphones are plugged in”. I went to the Sound applet in the Win 10 Control Panel, and it said no audio devices were installed. I looked at the sound devices with the Device Manager, and except for a signing problem with a device I’ve used, they all looked fine. I went to the Lenovo website, asked them to recognize and scan my computer, and they did. I ran their sound diagnostics. It reported only one sound device, the NVIDEA one, and said it is working fine.
I went to their service bot and entered information about the issue. I said it couldn’t help me, and asked if I wanted to contact them by telephone. I said yes, and saw this:
That was strange because it is 8:00 AM where I am now. I ignored the grammatical error. I created a service request. Now I’ll wait.

I sent off a service request. After a day or so, I got an email requesting that I do some tests. One of the tests was booting into the BIOS, and seeing if I got a beep. Unfortunately, the instructions for invoking the BIOS upon power up were for some other computer, and involved hitting the F1 button that was permanently lit up. I finally found out how to get into the BIOS. No beep. I relayed the news back to the tech via email. After a couple of days, I got a notice saying that they’d ordered a speaker, and would send a tech out to install it.
The speaker was delayed, but after couple of weeks I got a call from the tech to arrange a time for him to come by.
He came and replaced the speaker.
No joy. No sound. The F1 button is no longer lit, but that’s the only difference.
Lenovo will order a new motherboard.
