This will work provided the BIOS BootBlock isn't screwed up while your Main BIOS Image is gone so remember when flashing DO NOT FLASH the bootblock.
The bootblock is to initialize emergency BIOS recovery for some reason the BIOS screwed up.
Download the CrisDisk here.
Do the following on a spare working computer to prepare the BIOS Recovery Drive:
Rename a working copy of the BIOS to bios.wph.I have tried this with Aspire 4530.
UnZip & Extract CrisDisk to a folder called CrisDisk.
Copy and Paste the bios.wph inside the folder
(Remember to replace the sample bios.wph in the folder with your working BIOS!).
Plug a USB Floppy Disk with a Floppy Disk inside.
You can try using a Thumbdrive but the chances of working with a Floppy Disk is higher.
Right Click and run and WinCris.exe with Admin Permission.
It will format the floppy, copy the MiniDOS files inside with the bios.wph to create a emergency BIOS Recovery Disk.
Do the following on the Computer which BIOS you need to recover:
Plug in the prepared USB Floppy Drive to the machine you need to recover the BIOS from on the left USB port which is the motherboard main USB (There are 2 such ports on the same side).
Remove battery and AC Adapter.
Press and hold Fn+Esc then plug the AC Adapter in while holding Fn+Esc.
Press the Power Button Once and release while holding Fn+Esc.
You should see the lights flashing meaning the laptop is in BIOS Recovery Mode.
The USB Floppy drive should be lighted up and you should hear the floppy drive reading after that you can release Fn+Esc.
After a while you should see either it power off itself or the laptop lights stop flashing.
Remove the AC Adapter, USB Floppy Drive.
Plug back the AC Adapter your laptop should be working again.
Insyde BIOS recovery is different.
1)EFI doesn't need a bootable thumbdrive because EFI uses GUID Partition Tables just a normal partition will be ok (I think).
2)You need to rename the EFI to the correct name so recovery bootblock will identify the correct firmware.
thank , i really need this.,
ReplyDeleteis it work on aspire 4715z???
Hi there, thanks for your site!
ReplyDeleteMy notebook (Aspire 5024WMLi) froze a few hours ago while I was working normally. After powering it down and up again it will only spin the HD and DVD drives for a second, it won't boot and the screen stays black.
I followed your instructions (with the newest BIOS from acer.com and an USB stick), but the notebook only starts to send the VGA error beep code (1 long 2 short) for hours. The USB stick powers up correctly. Any advices?
It is not always the BIOS error, mayeb the VGA has fried.
ReplyDeleteHave you tried reset the BIOS?
Try press hold power button with no power supply for 30seconds?
Thanks, I tried, but it didn't help. I wonder why the BIOS doesn't give beep codes. It only does so when trying to do the emergency flashing procedure, or when e.g. starting up without RAM (2-3-1).
ReplyDeleteBIOS recovery is for people who did a failed BIOS flashing procedure, if your computer sudden;y doesn't boot it is hardware failure.
ReplyDeleteYeah, but it was worth a try. Seems to be time for a new one after 4.5 years.
ReplyDeleteAgain thanks for your time, bye! ^^
You can also try baking the motherboard to melt the solder and reconnect the broken circuits.
ReplyDeleteGoogle internet for solder reflow.
I have tried this with Aspire 4530.
ReplyDeleteit works for aspire 5520G
ReplyDeletethank you very much, it was very helpfull

ReplyDeleteACER ASPIRE NETBOOKS USES INSYDE BIOS NOT PHOENIX
ReplyDeleteI have an Aspire 4530. I tried flashing the 1.3336 version, but the WinPlash application stopped responding midway. Before I followed your steps my laptop would exhibit symptoms similar to the 1.3335 bug; however, now it freezes after the initial acer screen. Do you know what could be causing this? Thank you for your help.
ReplyDeleteHi Admin,
ReplyDeleteI was looking for your 4530 1.334 SLIC 2.1 with voltage tweaks but it seems the link is down.
Is that still available?
