Hello everyone,

Im having big trouble with my Acer a715 71g notebook. Last month there was an bios update and during installation electricity stopped working and notebook wasnt able to startup again (even not into bios). I sent it to local repair shop and they fixed the bios chip and then returned to me as "functional". But when i turned it on There is no bluetooth, usb and webcam in device manager. there is just UNIVERSAL SERIAL BUS and xhci usb with ERROR CODE 10 and yellow warning triangle. When i plug my mouse into notebook - no red light, but flashing and when i plug my usb with led inside, it is lightning, but notebook does nothing when its plugged - but voltage is definitely there, checked it with multimeter.

When i go into bios (INSYDEH20 BIOS) i cant see usb, or bluetotoh there - even when i got into the ADVANCED SYSTEM with the metod from internet i saw.

I dont know what to do honestly, i really need to use mouse while working on my laptop. I think, there is definitely problem with usb controller, idk, if it is not because of not compatible bios chip?

Can anyone help please?

I have seen simillar problem on some forums, but never any solution.

Thnak you all for your thoughts and sorry for my English

    Bring it back to the local repair shop and complain about these issues. Alternatively bring it to Acer Services in your country it may still be under the 2-year warranty, the EPROM may need to be reprogrammed or even replaced that only Acer Services can do.

    Thank you! Unfortunately the 2 years warranty is over and local shop doesnt know what to do. Can you please tell me what EPROM is? Do you think it is bios chip problem? or eprom is different electronic part?

    Im not really sure, if it can be bios chip problem, because the system boots up normally, windows is working, and if there would be problem with bios, the pc will not turn on, hm? Just thinking

    There is also 1 MORE STRANGE thing with the laptop - it wont shutdown properly anymore…have to hold the power button for like 6 seconds
