Have you ever had a working PC that wouldn't go into the BIOS mode?
o https://i.postimg.cc/GpkgdmxT/cmos01.jpg Won't go into BIOS

How did you resolve that issue?

1. The Windows machine boots to POST & then Windows 10 just fine.
2. Once booted to Windows, the USB keyboard & mouse work just fine.
3. But I can't get the PC to respect the BIOS F10 key press.

These are the key presses I know used to work:
o BIOS Menu === F10
o BOOT Menu === Escape
o DIAG Menu === F9

And yes, I'm pressing them (all the time) specifically at POST
o When it says to press "F10" to get into the BIOS.

It's like the keyboard isn't even there...
o The BIOS battery is only a few months old.

The reason I want to access the BIOS is I need to change the HyperVisor
settings for my AMD-based Foxconn motherboard for an Android emulator:

Yes.

How did you resolve that issue?

Short a certain pin that would reset the UEFI configuration.


That was one case.


Another was removing any disk, because the machine was in hibernation,
and thus refused to accept enter bios till a real reboot happened. And
the disk said there was an hibernation image.

Arlen,

Does this PC's motherboard have PS/2 inputs for keyboard and mouse? (usually green and purple)

I've had older systems that the USB keyboard and mouse were not useable until Windows loaded.

Using a PS/2 style keyboard solved the issue.

Just a thought...

Yes, when using a usb dongle for a wireless keyboard/mouse. Workaround is that
when I need to access the bios menu is to boot with the dongle unplugged and
a ps/2 keyboard plugged in.

Hi JT,
I don't see any PS/2 inputs, nor do I have the keyboard anyway.

Here's what happens with the Genymotion Android 10 Pixel3a emulation:

And here's what happens with the VirtualBox virtual machine:

"AMD-V is disabled in the BIOS (or by the host OS)

Googling, there's "apparently" a way to force the CMOS to come up
o Apparently by shorting a jumper somewhere (but I'm not sure where).

What model PC?

A pic of the back of the motherboard with all the inputs would be helpful.

The PC make & model was listed in the opening post.

What I did was remove everything possible connected to the desktop.

The strangest thing is this Hyper-crap, which I never understood.
1. Apparently, I have to turn it "ON" in the BIOS
2. But I have to turn it "OFF" in Windows (Turn Windows features on or off)
https://i.postimg.cc/zD2nHQqQ/cmos05.jpg

That makes no sense (to me) and, worse, is quite unintuitive (to me).
o But that's the only way I could get Android emulation to work.
https://i.postimg.cc/hjGjkX9X/cmos06.jpg

In summary, two things had befuddled me to no end (they made no sense):
A. I couldn't get to the BIOS with "stuff" plugged into the ports, and,
B. You have to turn Hyper-crap ON in BIOS and OFF in Windows,
C. Just so that Android emulation will work (on an AMD CPU).

Hi David W. Hodgins,

I solved the inability to boot to BIOS for a few days using these steps:
1. I turned off all power
2. I removed EVERYTHING that wasn't essential
3. I put the power back
4. I held the power button down for 10 seconds & then once up & down
5. When it booted to POST I tapped the F10 key
6. And I was able to get into the BIOS (for the 1st time in a days trying)

Note: I'm not sure if every step above was needed; but that's what worked!
o https://i.postimg.cc/RhSXCJQn/cmos04.jpg

The result was I could turn the virtualization ON in the BIOS.
o And then OFF in Windows (Turn Windows features on or off).

To me, that makes zero logical sense (certainly it's not intuitive)...
o But it worked, so I can move on with my Android "hello world" emulation

I had this happen here recently.

It smacks of software having done it (OS into UEFI).
Both PS/2 and USB keyboards disappeared at the same time,
and could not be used at BIOS level. No other setting
was affected. The settings have a crude checksum mechanism,
and there was no message indicating a problem.

It took Clear CMOS to restore function, so I could
press Del (Asus) and get into the UEFI BIOS setup screen.

Clear CMOS is to be done with all power off. No +5VSB
should be present. Many instructions are missing that detail.
Asus on multiple occasions, had to release a one-page PDF
correction to the user manual about this. If you leave
the power running, the Clear CMOS button can short
out the OR-ing diode on VBAT and burn the diode.

UEFI is just a too-insecure technology. As predicted.

I have a similar problem on my Ascer Aspire 5 laptop. The manual says
press F2 when booting to get to the BIOS, but I have'nt been able to get
that the work. My workaround? Windows 10 actually has an option to boot
to UEFI Bios in the Recovery-Advanced Startup pages. One of the options
under Advanced Startup is to boot to UEFI. Just make sure everything you
have going is ended and/or closed before going there.

I found out when trying to get the system to leave my keyboard lights on
all the time. Acer turns them off after 10 seconds of inactivity - they
had to do that to get their Energy Plus rating. Due to the number of
complaints, they just upgraded the Bios to give the option to keep them
on all the time WHEN RUNNING ON PLUGGED IN. They will still turn off when
running on battery, and it can't be changed.
