My son's ACER 5552 laptop is not booting properly. Press the power switch and the power button light comes on but nothing else happens.
I downloaded the most recent bios onto a usb stick and went through the routine of remove battery, remove power cable, hold FN ESC down, insert power cable, switch power on which I understand should update the bios. Sounds indicated that the fan was on, hd was spinning and the DVD drive made noises but nothing appeared on the screen.
I connected the vga socket to my tv as a screen check and nothing appeared.
I removed the CMOS battery and then replaced it but that made no difference either.

Might be a bit old topic but... I had the same issues with same model
FN + ESC did not work.
My solution
1) Prepare a usb stick with latest bios
Download it from acer site
Copy the fd and flashit.exe from dos folder to root of usb stick
Rename XEWxx214.fd to BIOS.FD or zg5ia32.fd I had it with both names ;)
2) Open back cover remove battery and RAM. Under Ram there are two solder's close to each other, short circuit them with a screw driver While shorted these contacts press Power button and keep it short circuited for a like 10sec Close pc from power button. Insert RAM and battery
3) Insert usb stick to left port, plug ac power
Keep FN + ESC pressed and press power
The fan should start spinning faster now. I got NO other indication
I left it like this for a couple of minutes and then it shuts down on it's own
Then i started it and voila it was working.
Might need try last step a couple of times till u get it correct
