Hello, just wanted to share my solution to updating the bios of v5 473p when you encounter a black screen. I was having problems because Acer only had the .exe file for the bios of this version laptop. When you want to update the bios from a usb stick, it does not contain any directions. This may work for other models too, so here is what I did to get this to work!
1. Download the latest .exe bios file from Acer's website.
2. Run this file from any laptop or desktop.
3. When it fully opens, it will say wrong version laptop or something to that effect.
4. Goto your temp direction where it was temporarily extracted (c:\users\(your username)\AppData\Local\Temp. 5. Locate the folder where everything was extracted (in my case it was 7ZSDF07.tmp. (the file that you really need is the .fd file!)
6. Copy all these files to a formatted FAT32 USB stick.
7. Take the usb stick and plug it into your V5 473p.
8. Plug in your power cord, with your fingers holding down FN and ESC buttons, power on laptop at same time.
9. Let go of power button and keep pressing FN and ESC buttons (you should see your usb stick reading) but your screen will not show anything.
10. Keep holding for up to 3 minutes. Your laptop will shut off or power down.
11. Take usb stick out and power up, your screen should be working!
This took me a few days after googling and trying to extract the exe file with 7-zip. However with 7-zip, it doesn't fully unzip everything as it was missing the .fd file. Hope this works for you!!
