aspire tc120 could not start up

Hey！guys！I have made very stupid mistake. I tried to install adobe ps but it always showed 0% so I planed to restart the computer to see if it could change. But when I restart it it shock in the acer aspire screen with buffering then I put the power button and press the button again with bluetooth of keyboard‘s del key since I want to enter the bios and choose last default setup but the pc just turn to silence. And the screen is black with no signal， only the fans of cpu works. WHEN I get off the memories the graphic card it still like this and no alarm like beep beep.

WHAT SHOULD I do genius？

really in hurry！
and hope you guys could help me with it @IronFly

It seems like the system did not start from the hdd and only stack here with the light of power flashing

First turn it off and make sure it's really off by pressing and holding the power button until all fans are quiet. Next turn it back on normally and try to get into the BIOS with the delete key. Do you see anything on the screen during this part of the boot process? Is the monitor cable still hooked up solidly?

Hi，Billsey, thanks for reply. I got off the cmos battery and the good news is the light of hdd now flashing like the power button, but the screen still no signal. maybe I need a usb keyboard for entering the bios.

Only the light of hdd and power button flashing. And when I plug in the cable it will start automatically even not press the power key.

I pressed the del key but nothing on screen.still no signal！

is this situation shows the motherboard died？

billsey

It's possible you have bricked it. You should have a keyboard connected either with a USB wired or wireless, not a bluetooth. Does anything show up on the monitor at all? You are going to need to be able to at least get into the corrupted BIOS to be able to repair it, because the BIOS is going to have to run far enough into POST to allow it to boot off something.

I think I need recovery the bios with flash disk now. I had download the newest bios from acer.com，but do I need to rename the file and there are 4 different files which should I copy to flash disk? they are like the photo of attachment.

And my keyboard is wireless one not bluetooth one，sorry for the wrong information@ Billsey

billsey

First you will need to make a USB drive bootable. Next copy all over as shown for a Windows boot (it'll use the EFI folder). The actual install will be from the Win folder using the files in the ROM folder. The DOS folder might have a floppy disk image in it that would boot and install if you have a floppy disk drive and floppy disk.

thx billsey. Now the problem is how to write the bios file into pc.I saw a case which use fn+Esc to write it into the pc but the thing is the keyboad of usb usually do not have fn key.

billsey

Yeah, the key is to get it to recognize the USB as bootable and actually boot from it, or add a floppy and have it recognized as bootable.

updated today. with my wireless keyboad it did not work still flash and darkscreen. Will try to borrow a wire keyboad to have a try. Learned a little bit from youtube about fixing the black screen problems but seems not works for desktop！

I'll give you a tip as per the service guide! I do not take any responsibility for any damage!

1) Turn off the notebook
2) format the pendrive in fat32 with the following commands in cmd as admin: diskpart, list disk, sel disk x (x is the number of pendrive), clean, convert mbr, create partition primary, format fs = fat32 quick, assign e active!
3) Get the rom file and change to RCVBOOT.CAP
4) Plug the USB stick into the notebook and turn on the notebook!
5) should begin the recovery process that will be followed by a long beep and a short beep
6) Select to proceed with the flash update and then press any key to restart!

bluehawana

the thing is that desk top did not boot from usb now and I could not flash rom into it.
