The power light on the power button turn on and off 3 three times
This would indicate that the system is attempting a BIOS Recovery.
If so, your BIOS is corrupted and needs to be re-flashed (without a BIOS to do so). If all else fails they may need to replace the BIOS chip at the factory (RMA).
For do it yourself fixes you need to be aware that attempting these may void your warranty. It the PC is under warranty then I suggest you send it in.
It would be of great benefit to you if you knew what you had for a BIOS. Legacy BIOS, a Hybrid, of a EFI/UEFI. The method you choose to do depends on which type of BIOS you have.
If you had a Phoenix BIOS the that would probably have been a legacy or hybrid. For that you could try this:

If you had an InSYDE BIOS and a GPT format hard disk then the recovery file would be on the hard disk.
The procedure is the same regardless of BIOS brand, but the file and flash program are different. You get the flash program and most recent file on a USB stick and initiate it with the key combination.
This method works for the Acer Aspire One.

I have heard that it will work with other Acer models, but which ones? That is a crap shoot.
In all cases the procedure is:
- Turn off the laptop
- Insert the USB stick with flash program and most recent BIOS file - file renamed to work with the particular flash program
- Press and hold the Fn+Esc keys, then press and release Power
- Keep holding Fn+Esc for a few seconds > release
- The power button flashes as the BIOS is flashed
- The system reboots when done
I do not know what will happen if you attempt this with the wrong flash program for your BIOS or on a system that does not allow outside flashing. Nothing? Flames?
So I will say again, if it is under warranty, send it in.
