Aspire A115-31 black screen BIOS Upgrade help
Hello Acer Users,
I bought Aspire 1 (A115-31) last year due to changing home i could not use it at all, it has just come out of warranty and i now opened it after 11 months to find it is not working.
The screen is black.
Upon powering up and putting it on, i can see the blue lights i can also see charging lights, but there is no display even after connecting external monitor, it doesnt even go to the bios routine as i donot see caps lock or num lock on external key board as well.
I have already tried multiple things, like:
1- resetting the BIOS by removing CMOS cel
2- resetting the BIOS by push button switch on mother board
3- FYI there is no RAM module it is all built in onboard so no chance for the RAM insertion issue
4- I removed the Battery, battery is fine i checked it with my multimeter
5- i checked the charger and the charging port both fine and at 19 V
6- Now i want to try to upgrade the BIOS through USB, hoever i couldnt do it as there is no help available to do it for this model
when i copy the BIOS extracted files in to my USB (FAT 32 Formatted fresh), and press Fn + ESC before the power key, screens lights up and a logo of "TianoCore is displayed"
I can see some USB activity at the same time as well but unfortunately this does not do anything and the screen again goes black.
I am assuming there is another way to make a USB and i am not making the USB correctly, can anyone please help me with this.
