2 short beeps = CMOS setting error
Download your Hardware Maintanence manual:
Refer to page 78 and page 442.
Hit F1 at bootup, go into Bios Settings, use F10 to save and exit.
Hit F1 at bootup, go into Bios Settings, use F7 to load defaults , then use F10 to save and exit.
Page 442 is a Boot block recovery
You may need to take the machine to a repair shop for this.
Note: The CMOS recovery jumper is an extremely small square piece with 2 holes in it.
You will need a magnifying glass and tweezers. Do not lose this item.
You will also need a copy of the BIOS flash on a diskette.
(BIOS flash on a CD should work).
Note: page 116 shows the CMOS recovery jumper, pointer 15.
Disclaimer: do page 442 at your risk.
Hopefully page 78 will work.

i have tried pressing f1 at boot with no success, it just beeps and nothing more happens, and now after trying a few times all beeps from normal startup (without pressing any buttons) have stopped but the computer does not turn on

You might have a dead CMOS battery???? -or- another issue.
I have a A57-9702 which is just before your machine came out. My CMOS battery is still good after 8 years.
