Acer Aspire One D250_Bios recovery

there is the macle's method for the A150 :

well,is there any method for the new AOD250? please help me...
Merry Christmas to everyone

 

Hi, I have tested the following instructions for the D250 and successfully recovered from a bad flash. Please note they differ from the D150 instructions as provided by ACER.

First format an USB stick with FAT, if this option is not available use a smaller USB stick (eg 1Gig)

Download the latest BIOS, and put both FLASHIT.EXE and the BIOS file in the root directory of the stick. Do NOT rename the BIOS file, it should be KAV60.fd

Now connect the USB stick to the AA1

Turn the AA1 off, DISCONNECT the battery but leaving the AC adapter connected. Press Fn+Esc, keep it pressed and press the power button to turn the AA1 on. Release Fn+Esc after a few seconds. Press power button if it begins to blink, otherwise do nothing. The AA1 will now initiate the BIOS flash, do not interrupt it under any circumstances. The AA1 will reboot shortly after. Wait patiently.

The BIOS has been flashed and all settings reset to default.

If for some reason you made a mistake during the procedure and it doesn't reboot by itself wait 5 minutes before turning it off, just to be safe that it isn't still flashing the BIOS.

 

I wonder why you have to disconnect the battery?

 

I'm not 100% sure. I got the idea from some generic Phoenix BIOS recovery instructions. But most importantly, I could only get it to work with the battery removed.

 

often recovery methods like this involve doing something that can almost never happen in real life circumstances.
they don't want people to accidentally enter the bios recovery mode.

 

Well if it works, you can't argue with that. Nice work.

 

Currently having a bad flashed bios, and with the above directions not working for me, I found this info from the D250 service manual:

now the problem is getting the wincris program from the acer oem support site. all the other wincris programs ive found either A) only support floppies, or B) require the bios to be renamed BIOS.WMH.

 

Hi there,

Have you tried getting hold of an external USB floppy drive!

Paul :ugeek:

 

well theres several versions of the wincrisis program out there.
the one that is offered by acer is the version i need, or any of the versions that support *.fd bios'.
the only problem is they don't offer it to everyone, pretty much if you have access to the service manuals you have access to this.

I can enter crisis mode no problems, its just my usb never flashes...

 

Hi,

Yeah, but if you get an external USB Floppy drive you could use the wincrisis which only supports floppies. If that one also suppoers .fd bios files.

Paul :ugeek:

 

well so far none of them support insyde bios, they are all phoenix.
not to mention, when flashing the bios, there might be certain flashing commands that are specific to the d250. its at least specific to insyde bios.

floppies arent the problem. (got a usb floppy from my OLD OLD laptop) its making sure I have the correct files on the usb device.

the correct files are hosted here: http://csd.acer.com.tw/
getting access to the site is another thing.
anyone work for acer?

 

I cannot enter this "Crisis" mode. What am I doing wrong? Every time I remove the battery, hold the Fn + Esc keys and tap the power button. It instantly turns green and if I keep holding the keys, it goes to PXE Lan boot. Otherwise, It stops at the bios password screen to which I do not have the password.

Any ideas on how to reflash this thing?
Also, is there a physical CMOS battery present on these netbooks like a typical desktop motherboard, or do they save the info to the chip and not rely on battery power?


Thanks,

Michael

 

To remove the password from a D250 you need to short out a jumper thats located inside the 3g card slot. With the connector closest to you, the jumper is to the top right, above the black masking.
You need to:
Disconnect Battery and AC
Connect the jumper (just short the two points together, anything conductive will do)
While keeping it shorted, connect the AC adapter and press the power button.
You can clear the jumper once POST is done
Restart the system and the password should be cleared. Enter into the bios settings to make sure after you have restarted.

Im still looking around for Insydes crisis software. Acer finally agreed for me to send the netbook back, but with ME paying for the shipping there. Say what you will about other companies like Dell, but they have always paid for shipping both ways on problem products Ive had that were under warranty.

edit: added a pic.

 

OK I got it.....

1. You must take out the battery.
2. Plug in USB flash disk with latest BIOS file and Flashit.exe
3. UNPLUG AC
4. Press FN+ESC and insert AC power cord
(Power light will flash orange for a split second)
5. Release FN+ESC
6. Press Power button
7. FAN will spin 100% and USB flash disk will light
8. Wait
9. System will reboot
10. Your done

Now ..my bios password is still there...any ideas?

Thanks,
Michael

 

re-read my above post. bios recovery mode doesn't affect the settings at all. You must use a jumper to clear the CMOS settings. Your post was just a minute after mine so you probably missed it while you were typing yours.

Got the number for level2 tech support in Texas (which is where they want my send my netbook). Will be calling in the morning to complain, ask for free shipping or just give me the crisis files to save everyone time and money.

The fine e-mail tech support is about as helpful as someone can be reading from a script. They tell me there are no recovery files and I must send it into the repair center. My response was a copy/paste from the d250 service manual mentioning the very subject of how to recover a bad bios flash. They just re-send me the shipping info.

 

Thanks! Yes, I did miss your post above, looks like we posted about the same time. I was able to short the jumper and reset the bios.

Now, I have to figure out how to remove the HD password. Any ideas on that?

Thanks again,

Michael

 

You can replace the circuit board on the hdd. (The underneath part) Thats about it.
If you cant find a replacement board for that model, just get a new drive on ebay, its the quickest, easiest way.

 

OK...Newegg here I come.

Thanks for all your help. Hope you get your BIOS issue resolved.

 

Hi stemcell here, if you have a dead Acer One D250 try the emergency flash using these tested files.

1. Insert your USB drive/thumb drive into a working windows system. Open up my computer or computer and locate your usb drive and right click and select format. Format the drive with ‘FAT’ file system and not FAT32 (Try to use a small capacity usb stick or a memory card in a reader, ie less than 256mb). Reason being mine would not flash using a 1 gig usb drive but it did using a 128mb sd card in a reader!
2. Download the attached zip file D250 Recovery.ZIP
3. Extract the files to the root directory of the USB Flash Drive.
4. Turn off the Aspire One and make sure that the power adapter and battery are disconnected from the netbook.
5. Plug in the USB stick to any port on the failed Aspire One
6. Whilst pressing Fn+ESC plug the power adaptor in (note battery is not installed)
7. Keep pressing Fn+ESC and then press the power button once. The power LED will now blink, after a few seconds let go of the Fn+ESC keys, it will now initiate the BIOS update, DO NOT INTERRUPT IT UNDER ANY CIRCUMSTANCES.
8. After about 2 minutes, the power LED will stop blinking and the Aspire One will turn off. The BIOS is now complete.
9. IF the unit DID NOT REBOOT BY ITSELF, wait a further 5 – 7 minutes before rebooting the unit as the BIOS may still be flashing.
10. Now the unit is off remove the USB drive you used to flash, Install battery and power lead and turn on.
11. You should have a working laptop
