    Laptop Thunderbolt USB C support

    Hi Guys.

    I just bought this Laptop and installed a fresh Ubuntu 19.10 after a bios tweak https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1

    Everything seems to be epic Ubuntu running great. Laptop itself a beautiful thing.
    Could have had more rom with a plastic case or this USB C equipped aluminium machine with less rom.. Its Soooooooo nearly perfect.

    Until I tried to charge from USB C instead of the barrel charger provided. = Laptop not charging with USB C

    I'm not sure if the laptop has USB C charge hardware anyway as I wiped windows off without booting it. And I have no manual for the laptop.

    I do note that in Ubuntu's settings:-

    "No Thunderbolt Support - Thunderbolt security level could not be determined"

    I have read that this can be a Bios issue but I have found no advice relevant to my machine online.

    Please help... What can I try ?

    Thanks.

    Re: Laptop Thunderbolt USB C support

    Ok.... in trying to find a option in the bios to enable Thunderbolt access I stumbled opon a selection under 'chipset' which was set to 'windows' .. I saw the option 'linux' so I thought it made good sense to select it, save and reboot.

    I can't get back into the bios now using the del button or any other.. The manufacturers logo does not appear at boot any more (which was the point at which I selected the del/bios button)

    Ubuntu still working... just cant get into bios to make changes that might be needed ????

    BIOS Vendor : American Megatrends Inc.

    BIOS Release Date : 10/30/2017

    Found that info out above... hope it helps ..

    Tried many combinations to get back into the Bios at boot.. always progresses to load Ubuntu.

    Re: Laptop Thunderbolt USB C support

    right... I noticed that my screen brightness slider appears to have reversed its operation ...

    So, what are the chances of my wrong selection in the bios reversing brightness at bios boot ?
    So, maybe I am accessing the Bios, I just can't see it ??
    I can certainly stop the boot ubuntu process by pressing del ... I had assumed I had paused the code.. Maybe im in the bios and I just cant see it ?

    Ideas ??

    Cold boot to get into UEFI or BIOS, remove battery or fwsetup
    http://askubuntu.com/questions/65296.../653006#653006 &
    https://askubuntu.com/questions/652966/unable-to-access-bios-menu-after-installing-windows-8

    Cold boot is to turn off all power, not warm reboot.
    Unplug from power. If laptop also remove battery. Hold power switch when off or 10 sec or so to drain all power. Then boot and immediately press correct key to get into UEFI/BIOS.
    That is controlled by fast boot setting in UEFI, which is separate or different from fast start up in Windows. But both settings are to make Windows boot faster as it is so slow. Fast boot in UEFI assumes no system changes, so UEFI does not rescan system for what hardware you have. Then it starts boot so quick, you normally do not have time to press any key before boot starts.

    Escape key should take you to grub menu, if you do not normally get it.
    Last entry in grub menu should take you back into UEFI.

    And from within Ubuntu you can reboot into UEFI.

    Reboot into UEFI:
    sudo systemctl reboot --firmware
    or
    sudo systemctl reboot --firmware-setup

    Many thanks ... I will try the above suggestions.

    I have a fanless laptop.. I have seen a video of people taking the back off (a set of screws) ... but the battery maybe looks a bit integrated. Would this type of laptop have a separate bios battery ?

    Some systems with battery built in like that have a tiny hole in back for reset.
    It may have motherboard battery or not, no idea.
    Hopefully the other ways to get into UEFI/BIOS work.


    Have you updated UEFI/BIOS from vendor for your model.
    Many systems need UEFI updates.

    Had a couple of things happen this week setting back my progression with the fix. RTC with airbags deployed.
    Have not forgot the thread.

    Re: Laptop Thunderbolt USB C support

    Hi Guys.. Got my Bios sorted.

    Unscrewed the back and disconnected the battery.. scary times !

    So... here is a photo I took of the bios and the setting I changed to 'Intel Linux' ... By changing this I could not get into the Bios and my screen brightness slider reversed polarity.. ??
    Anyway... back to normal now with the Windows setting.

    Now... Hopefully I can try some things in the Bios with guidance to see if USB charging is possible on this laptop ?
    With thanks.
