i have acer aspire E5 571 .... when i purchase it i saw that most of windows not supported due to UEFI Boot so it needs update through an usb ...... i update it successfully to both UEFI and Legacy .. and i gave it to my friend to charge the battery and use it .... after just two days ... the laptop won't turn on at all ... it just when you push the power button ... just a blue light show up for 3 sec ..... and it turn off again ... no signs of fan ... nothing on ..................... i need help to fix it myself .... and thanks all
