that MS provides, with islands and trees, but not a real place iiuc,
appeared and stayed for 10 seconds, and then the screen went blank
again.

How can that be?

I thought, let's check out the BIOS but how will I know if the wireless
kb is letting my press the right F-key. So I went to my suitcase and
got my own wired keyboard and mouse. "Have keyboard, Will Travel. Wire Paladin. San Francisco."

And by golly it started right up.

Turns out the switches on the wireless keyboard and mouse were both off.
When I turned them on and unplugged my kb and mouse, the pc worked fine.
So why didn't the PC turn on and complain there was no kb or mouse? I
know mine has done that some time in the last 10 years.

Perhaps whatever handles the wireless devices, reported to the BIOS
that they were HID devices, but without anything to generate an
actual event, there would be no way to do anything at BIOS level.

Whereas the OS asked a few more questions when loading a driver.

If it's a 2-in-1, then it's probably touch and thus doesn't need a keyboard and mouse?

Did you attempt to reduplicate/validate the exact same problem?
- Shutdown device, disconnect your wired keyboard/mouse, turn off
owner's wireless keyboard/mouse...then power on.


If the device had Spotlight for the Lock Screen previously
configured(pics provided by Bing, changed periodically[every 1-2 days)
and deployed using code called the Content Delivery Manager(CDM)that communicates with Windows use of Bing's online pictures.
- at power on, the configured Lock Screen pic source/location is on the device's storage(SSD/HDD). When the CDM does not obtain a new pic from
Bing the display for the Lock Screen reverts to one of two sources - the existing default or a blank screen.
=> The rendered pic or blank screen is rendered independently of the keyboard/mouse status(wired/wireless type and on/off).

The timing/sequence for activation of the Lock Screen is also dependent
on other variables(hardware[graphics card/driver], Windows, internet,
SSD/HDD) not necessarily activated in the exact same order at power up

Until the same problem can be duplicated and more info presented, the
possible cause/reason is pretty much a wild a*$ guess.

**As you can see from the webpage above, and as my SIL said, it's sold
with wireless KB and mouse. Why do they do that? Corded devices are
more reliable and very, very few users sit so far from the
monitor/computer that the cord does not reach.

Wired devices don't have batteries that go dead, don't have switches
that need to be turned off when not using them or turned back on when
you again want to use them. Are computer vendors pushing wireless just
so they can charge a small number of dollars more than wired cost?

Everyone wants battery operated things nowadays. It's all the rage... keyboards, mice, laptops, iphones, drills, leaf blowers, lawn mowers,
cars, drones, toys, pets... etc. Be the first on your block to have
one. Be there or be square, as the wise old saying goes.
