    Thanks for your reply, but after trying google and a generic miniPCI bios that I bought from China, I managed to fully recover my Laptop. Contacting Acer is as good as Throwing your laptop for good. I know cause I'm a professinal laptop repair tech in KSA and acer always recommends replace board in this kind of problem.

Unfortunately not unless, you have a dual bios where the old settings are saved, flashing the bios is very dodgy, unless it is absolutely neccasary. You may be better getting in touch with acer to se if the laptop can be reset.

According to my troubleshooting manual of Acer Aspire 4520-Z3 about

BIOS Flash Utility:

The BIOS flash memory update is required for the following conditions:
New versions of system programs
New features or options
Restore a BIOS when it becomes corrupted.

Use the Phlash utility to update the system BIOS flash ROM.
NOTE:
If you do not have a crisis recovery diskette at hand, then you should
create a Crisis Recovery Diskette before you use the Phlash utility.
Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Phlash.
Please use the AC adaptor power supply when you run the Phlash utility.
If the battery pack does not contain enough power to finish BIOS flash,
you may not boot the system because the BIOS is not completely loaded.

Follow the steps below to run the Phlash.
1. Prepare a bootable diskette.
2. Copy the flash utilities to the bootable diskette.
3. Then boot the system from the bootable diskette.

The flash utility has auto-execution function.
---------------------------------------------------------------------------------------------------------------------------

You need to prepare a bootable Flashdisk into dos mode
then you should search for the above mentioned crisis recovery
diskett and transfer its content to the flashdisk.

I read from another forum that for recovery of Aspire 4520 problem
can be done through pressing of the keys combination as follows:
press FN + ESC and hold them, then just hit the power on button
and release it, after awhile "the power button" should blink red,
release the keys FN+ESC and don't touch anything.

After successful of recover the bios it should restart normally.
That happen after 20-30 minutes. If it doesn't restart just repeat the
process.

Hope it helps

I try update my bio on my ao0751h netbook acer, and doesn't successfully, now my netbook doesn't turn on. How i recovery a bios?


Solution 1: Boot-block BIOS
Modern motherboards have a boot-block BIOS. This is small area of the BIOS that doesn't get overwritten when you flash a BIOS. The boot-block BIOS only has support for the floppy drive.If you have a PCI video card,you won't see anything on the screen because the boot-block BIOs only supports an ISA videocard.
Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy and execute it automaticly by putting awdflash *.bin in the AUTOEXEC.BAT file.
AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette. Copy and rename the correct BIOS file on the floppy and power up the PC. The floppy doesn't need to be bootable. You will see the PC read the floppy, after about 4 minutes you will hear 4 beeps, this means the transfer is done. Reboot the PC and modify the CMOS for your configuration.
Solution 2: Get a new BIOS chip
  1. Contact your motherboard manufacturer to see if they sell BIOS chips. Some motherboard manufactures send them for free.
  2. Contact a company that sells pre-flashed chips, like Unicore Software, FlashBIOS.ORG, BadFlash or Bios World
Solution 3: Hot-swapping
Note: I'm not responsible for any damage this method may do to you or your computer !
  1. Replace the corrupt chip by a working one. The best option is to take the working BIOS chip from a motherboard which has the same chipset although that's not absolutely necessary. It just has to give you a chance of booting into DOS. Before pulling the working BIOS chip out of it's original motherboard, set the System BIOS cacheable option in the BIOS to enabled.
  2. After you have put the working BIOS in the motherboard with the corrupt BIOS boot the system to DOS (with a floppy or HD).
  3. Now replace (while the computer is powered on) the working BIOS chip with the corrupt one.
  4. Flash an appropriate BIOS to the corrupt BIOS and reboot.

Solution 4: (for Intel motherboards)
  1. Change Flash Recovery jumper to the recovery mode position (not all products have this feature)
  2. Install the bootable upgrade diskette into drive A:
  3. Reboot the system
  4. Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.
  5. Turn the system off
  6. Change the Flash Recovery jumper back to the default position
  7. Leave the upgrade floppy in drive A: and turn the system on
  8. Continue with the original upgrade

"bootlock" When I turn the computer I get a message


The Boot Block

The preceding section discusses updating the program code in the system BIOS by flashing it (replacing it under software control). If the flash procedure is done improperly, the BIOS code can become corrupted, which will cause the system to go into an unbootable state. Many newer systems come with a feature where a 4 KB "boot block" program is included as part of the BIOS. This is a tiny piece of code whose job it is to recover from a situation where the BIOS code is incorrect or corrupted.

If your motherboard supports this feature, when the PC tries to boot and finds the BIOS code corrupted, the boot block will try to recover the BIOS code, usually by reading it from a specially-prepared floppy disk. You may have to change a jumper on the motherboard to enable this capability, and you may need to make use of a "plain vanilla" ISA video card. The boot block will load the BIOS code and then when you next reboot, the regular BIOS code should be in place and the problem resolved.

You will need to follow the special recovery procedure outlined by your motherboard manufacturer if you want to take advantage of this feature.

How can i recover the bios


Flash Recovery-Config Some motherboard makers incorporate a flash recovery-config jumper or boot block recovery jumper on their motherboards. This can often be used to recover from a bad or failed flash. On most machines a small segment of the flash ROM does not get overwritten when you perform a normal flash update. This small portion of code contains a basic boot block which can enable the machine to reload another BIOS from floppy disk.
If you have a laptop or desktop without a floppy. You can either fit a floppy in the conventional manner or in some cases a USB floppy or CD-ROM can be used.
