I'm hearing some unwanted sound after I turned-on my acer netbook. Also the monitor is keeping on blinking when the sound comes out. It's like a sound of a small blower or a small dynamo. I'm afraid that it might get blasted if I turned it on again.

You need to preform a Acer Aspire One BIOS Recovery

instructions here: http://macles.blogspot.com/2008/08/acer-aspire-one-bios-recovery.html

Summary:
You need a flash drive formatted as fat (Right click on drive. Click format. Select fat for file system. Press start)
Down load the bios 3310 from here: http://macles.blogspot.com/p/acer-aspire-one-bios.html
Extract all files. Put both FLASHIT.EXE and the BIOS file with FD suffix in the root directory of the flash drive. The files must not be in a folder. Rename the BIOS file to ZG5IA32.FD before proceeding. It only works with this exact filename.

Make sure laptop is off and has battery and power plugged in.

Plug in flash drive to netbook. Press Fn and Esc simultaneously, keep them pressed and press the power button. Release Fn+Esc after a few seconds. The power button starts blinking at this point. Press it once. The netbook will now access the files on the flash drive and initiate flashing the BIOS. After a while the power button stops blinking, and the netbook reboots by itself. Wait patiently.

If it doesn't reboot, but keeps blinking, wait at least a few minutes before turning it off, and try again.

Check the ribbon-cable between the motherboard and the LCD screen. It is not transmitting 100% of the video-information.
Be sure that it is not "crinkled", and that it is tightly connected at each end.

hi this issue is with ribbon cable it is connect between the mother board and your LCD screen. the cable required change. if you can change it OK other wise take it to nearest service center.

Just sounds like the black screen of death... It happened to me after I turned it off normally.

Here’s what you need:

1. USB Memory stick (as low as 128mb)
2. Another PC with a net connection
3. WinZip, WinRAR, or some other program that can extract zip files.
4. A quick visit towww.acer.com
5. Your Acer Aspire One, that will power up/turn on, but the screen does not come on.

And here’s what you do:

1. Go to www.acer.com and go through the DRIVER support pages until you get the Aspire One driver page for your relevant Aspire One model (110/150/751)
2. Click on the tab on the download area that reads ‘BIOS’ even if it looks like you can’t click on it (their site design grays it out but it’s there) and download the BIOS file numbered 3310 (it might have changed version recently but do it) and don’t worry, you can trust this file, as it’s from Acer directly.
3. Extract the zip once downloaded and find in the DOS folder the files ‘flashit.exe’ and 3310.fd
4. When you’s ve found them, rename 3310.fd to ZG5IA32.fd and put this renamed file and ‘flashit.exe’ onto the USB memory stick
5. Put the USB in the Aspire One and hold the keys ‘FN’ (function) and ‘Esc’ (escape) and keep them held when you turn the laptop on
6. Watch the power button and when it starts flashing, press it once (DO NOT DO ANYTHING ELSE)
7. You should notice the USB (if it has a light) blinking as well… The netbook has started ‘flashing’ the BIOS and after about 7 minutes, the netbook should shutdown and reboot itself and VOILA! The screen should turn on just fine.

It took my three times but this IS the proper solution! I am now very happy with my Aspire One that still works!

The problem here is the Acer Aspire One suffers from the black screen of Death, it's a BIOS error I have three Acer Aspire One's and I have had this problem and fixed it.

Here’s what you need:

1. USB Memory stick (just need one as low capacity as 128mb)
2. Another PC with a net connection
3. WinZip, WinRAR, or some other program that can extract zip files.
4. A quick visit to www.acer.com
5. Your Acer Aspire One, that will power up/turn on, but the screen does not come on/stays black.
   

And here’s what you do:

1. Go to www.acer.com and go through the DRIVER support pages until you get the Aspire One driver page for your relevant Aspire One model (110 or 150 or 751)
2. Click on the tab on the download area that reads ‘BIOS’ even if it looks like you can’t click on it (their site design grays it out but it’s there) and download the BIOS file numbered 3310 (it might have changed version recently but do it) and don’t worry, you can trust this file, as it’s from Acer directly.

5. Put the USB in the Aspire One and hold the keys ‘FN’ (function) and ‘Esc’ (escape) and keep them held when you turn the laptop on
6. Watch the power button and when it starts flashing, press it once (DO NOT DO ANYTHING ELSE)
7. You should notice the USB (if it has a light) blinking as well…
   
8. The netbook has started ‘flashing’ the BIOS and after about 7 minutes, the netbook should shutdown and reboot itself and VOILA! The screen should turn on just fine.

This is tried and tested. It took me three times because I messed up step 6 a couple of times but my netbook worked after the third attempt.

Hello,
power is there in your system so try following DIY:
1.Refix the battery once.
2.Any windows sound is there or not while turning on? if yes then issue with LCD.
2.Please check while turning on all the LEDS asre blinking for a once or not? If not, then the issue is with mainboard.
3.If the LEDs are blinking once and there is no display then the issue might be with RAM and refix them once.
If refixing doe not rsolve the issue then need to change.

Thanks.

Unfortunatley, its sounds like some type of hardware failure, either graphics chip, inverter or similar. It would be difficult to say which without a detailed inspection. I would recommend taking it to a repairer if it is out of warranty, or contact acer for more advice.

sounds like your broke your screen. you can test by using an external monitor.

That once happened to my LCD screen. I had to send it to the supplier for a fix. If it's still under warrenty, try sending it back for a replacement.
