I have an acer nitro 5 AN515-52-77S9 laptop. The driver page has listed a new BIOS update which says "1. Add ABST support. 2. Update Microcode to 0x96" Can someone please explain what does ABST mean? I assume microcode is something related to intel drivers. Is that right? Also, in case the new BIOS causes some instability, can i revert it back? Thanks in advance.

    From a German user the same information: After flashing BIOS 1.22 the keyboard backlight goes out after 30 seconds, even though mains power is used.
    Really a strange idea from Acer, if it was intended. If there doesn't come a patch, I will not flash version 1.22 on my AN515-52!
    Edit: @magnetoeric: Fine, that the change of backlight timeout behaviour doesn't bother you, 'cause when you've flashed a new BIOS you can't go back to an earlier version!

    Thanks for the link. So this is related to UEFI boot. I'll update it nevertheless since there's a microcode update

    также оно (обновление) появилось и на странице ноутбуков Prredator PH 317-52 (Helios 300) с таким же описанием. После обновления изменился режим работы подсветки клавиатуры. До обновления она не отключалась сама, только через Fn-F9. Сейчас гаснет через 30 сек. бездействия и включается по нажатию любой клавиши. Вопрос к тем кто тоже обновился, у всех стало так?

    You're right. The new update has changed the backlight timeout. It doesn't matter to me, since i use an external keyboard most of the time :#

    Just what i thought. Thanks for answering. And i hope Acer would revert to the default behaviour in the upcoming updates.

    Hi all,

     

    We apologize for all the confusion this has created, I want to clarify that the intended behavior of the backlight on all Nitro's 5 and Acer models is to always turn off 30 seconds after the last key stroke, this is not a bug but a feature (is not new), and it is a power saver (it does save on battery life).

     

    Please refer to the following knowledge article link: https://us.answers.acer.com/app/answers/detail/a_id/34903 We will provide your feedback to our design/engineering team for future consideration, but at the moment theirs no information that this feature will be changed.

     

    Note: This thread will be now closed and this marked as the official solution.

     

    Sorry for any inconvenience this may have cause,

    Acer-Manny
