    Yes. But no quotation marks (") and no plus signs (+). Only type the word      flash  Then press the Enter key.

    >>> I restarted by power button and have stuck when BIOS progress bar going to 75%>>>

    >>>The screen color was alway black>>>

     

    If the screen was always black, how do you know the BIOS progress bar was stuck at  75% ?

    I have the same problem with 4750G. This seems be a critical problem with this laptop. I tried many things but unsuccessful. I am very disappointed with this laptop. I probably will buy another laptop of another mark. It is impermissible for a computer to have the bios corrupted without any cause.

    My wife turned off her Acer Aspire 4752 while it was updating windows. The result was that it wouldn’t boot further than 75% of the progress bar. I read all the posts, scoured the web and followed every suggestion and advice from countless people but nothing, absolutely nothing worked and the laptop would never go any further than 75% of the progress mark. My solution was to purchase a fully working bios CMOS chip from Taiwan – sold on eBay. On the 4752, the CMOS chip is hidden under the Wi-Fi card. Using Amtech solder flux, a fine tip soldering and or iron heat gun, remove the old CMOS chip and replace with the one from Taiwan. It immediately fully booted into windows 10 and has worked perfectly ever since.
