The USB 3.1 port has PowerShare (Toshiba calls it USB Sleep-and-Charge), which lets the computer be asleep and the port remains available for charging.

Usage and troubleshooting ∞
Windows setup notes ∞
See Windows 10 configuration, redux
Booting from USB ∞
These instructions are copied from the 3180 and don't appear to work well.
Booting from either USB 2.0 or 3.1 will work.
- F2 configuration:
-
> Security
- Firmware TPM: Disabled
-
> Boot
- Fast Boot: Minimal
- Secure Boot: Disabled
- Legacy Option ROMs: Enabled
- Boot List Option: UEFI
- Attempt Legacy Boot: Enabled
.. now the thing is to set, and order, the items below.
(1) Add additional entries with "File Browser Add Boot Option"
- Give it a name, maybe something like
Boot from USB
- Scroll to that new name and press
enter
- Scroll to the device and press
enter
- Navigate to your
EFI
directory and select your.efi
file.
(2) Sort the entries
- Scroll to the list under UEFI Boot
-
Scroll to the entry you made (e.g.
Boot from USB
)F5
to move it downF6
to move it up
I went through this process to make two boot entries, one for the left USB (3.1) and the right USB (2.0). This will make it such that I can put a USB key in either USB port. Also, setting the boot order will let me decide if I want to prefer the left or right be booted up.
e.g. make the list:
- USB 3.1 (l)
- USB 2.0 (r)
- HDD1-Windows Boot Manager
-
HDD2-Local
- F12 configuration:
-
> Change boot mode setting
UEFI with Legacy OPROM; Secure boot: OFF; fTPM is OFF
If you see something like:
Change BOOT mode to:
Legacy Boot Mode, Secure Boot Off
UEFI Boot Mode, Secure Boot On
.. then you have misconfigured things. Return to the F2
setup and re-check those settings.
Opening it ∞
As I had repairs done, I got to observe the opening process
- Turn it over to see its bottom
- In the middle there is a small plastic cap covering a screw. Carefully pry it up.
- Nine screws should be visible, remove them
- Place the laptop bottom-down
- Open it as you usually would (screen facing you, touchpad in front of you)
- The edge closest to you dips down right in the middle. This is what gives you a small opening with which you opened the laptop a moment ago. Notice the top of the laptop is a plate with the keyboard and touchpad in it.
-
Pry up the keyboard-plate at the dip in the front. Be sure to use a plastic flexible tool that is wide, otherwise you will damage the plastic.
