A couple of months ago my wife's older Lenovo PC did a Win10 update then died. No lights, no fans, no noises.
She wanted a new one anyway, so we got Lenovo from PCWorld. I brought it home, did the various Win10 setup palaver, then it said it had an update to do.
It did the update, rebooted then died. No lights, no fans, no noises.
I took it back to PCWorld and was told that many Lenovo PCs that had been bought in the last week had failed the same way.
It was exchanged and has worked fine ever since. I went back a couple of weeks later and was told that an update had wiped/corrupted the BIOS Eprom in almost every Lenovo PC they had sold over a few weeks. All over the UK.
Then last evening, it requested a reboot for a Windows update.
On reboot, it gave a message "Start PXE over iPv4". Then "Start PXE over iPv6". Then it shut down.
A bit of googling said that it needed attention to the boot sequence in BIOS.
I went in and it had been set to boot from a network via iPv4 then iPv6. No option to boot from the SSD, USB stick or DVD.
I set it to the correct sequence (SSD then USB) and it now works fine.
What the **** is inside Windows updates these days?
