Re: Acer Aspire 1640Z BIOS problem

Dear all,

I also posted this one under "Notebook Bios Problems" which might notbe the correct place. Anyway here it is for you to see and maybe youcan learn from my experience.


Have done a VISTA upgrade with Acers upgrade DVD.
It recommended to upgrade the BIOS - after doing this notebook is dead.
(1 long and 2 short beeps).
If I want to flash a new BIOS with Crisis method which BIOS shouldI use i.e. how do I know if I need the AT or UMA version - how toverify this on the notebook (my version is 1642 ZWLMI)?

I would very much appreciate some help on this - thank you

I was a little bit worried when I started icon_sad.gif but later I was all smiles icon_biggrin.gif icon_biggrin.gif

So a BIG thanks to everyone who posted possible solutions here in this forum:

1: I bought a NEC model UF0002 USB floppy Disk Drive Unit.
2: Downloaded the zip file from the ACER homepage with the BIOS
(chose the one that should be the correct version for VISTA:
It contains 2 WHP files: ZL9A3A24.WPH and ZL9I3A24.WPH as I
learned from NoClaim's post I chose the ZL9I3A24.WPH.
3: Downloaded the zip files with the Crisis recovery zip-file (See d0gi's
post: ).
4: un-zipped the files
5: copies the file ZL9I3A24.WPH into the crisis directory - deleted the
BIOS.WHP that was allready there. And renamed ZL9I3A24.WPH
6: ran the WINCRIS.EXE program (did an unbootable format of the floppy)
7: I now had a recovery floppy.
8: all steps above obviously done on my desktop PC.
9: removed battery from my ACER 1640Z laptop
10: unplugged powercable.
11: inserted the USB floppy in one of the USB ports on the laptop
12: pressed the <fn> and <esc> keys
13: plugged the powercord
14: Turned on the laptop
15: waited a bit - lights came on on the laptop (no beeps)
16: waited a little longer and the light on the floppy came on
17: waited still a bit longer until I could hear the floppy was working
and then I let go of the keys <fn> and <esc>
18: after a while there was no activity on the floppy any more and
shortly after the laptop shot down.
19: the laptop started up again on its own and IT WORKED

Computer Post / Beep codes 1 long, 2 short, Indicates a video error has occurred and the BIOS cannot ... (two sets of different tones), Problem with logic board or SCSI bus.

Computer stops at verifying dmi pool data.... If none of the above recommendations have resolved your issue (attempt to reset the BIOS / CMOS settings to the factory or default settings).

Good Luck ! Please dont for get to Vote, Thank you.

Re: Acer Aspire 1640Z BIOS problem

J ai eu le meme probleme car il y a au moins 5 bios differents pour le 1640z.
telecharger utilitaire bios de phoenix
avec minidos et le soft pour creer une cle usb boutable afin de flasher le bios,
ce soft windows place 2 fichiers dos boutables sur usb en fat 16 et non en fat 32.
ajouter autoexec .bat dedans faut mettre PHLASH16.exe /x /s BIOS.WPH aujoute sur
la cle le fichier phlash16.exe founi avec et le fichier renomé BIOS.WPH de votre
sauvegarde du flashage raté. les 4 fichiers suffise. eteindre le 1640z et couper
le courant, enlever le dd et la baterie puis mettre la cle usb sur votre 1640z
ensuite, appuyez sur 2 touches fn en bleu et esc en même temps.
Mettre le courant et alumer le PC.
Attendre 4 sec et relachez les 2 touches. le flashage commence,
surveillez et quant le pc rebooute enlever la cle usb pour eviter la boucle du
recomencement perpetuelle du flashage car on ne peut pas flasher plus de 10 000 fois son bios.
Mon bios alviso 1219 et kbc 1A13 upc 1,700 Ghz pas de carte tv et carte grafique intel.
Avec cdroom j'ai jamais reussi le flasage, j'ai gaspilé au moins 10 cd roms. Acer ne fourni
pas assez d'esplications a ce sujet.

Tryed installing new bios upgrade,screen flickerd on reboot now is doa on reboot,model 1640z/xp home edition ?? what do I do !!


It should be ok, as this can happen quite often.

Remove the AC adapter from the laptop, then the battery.

Press and hold the on/off button for 30 seconds, then reinsert the battery (not AC) and hit the on/off button.
The laptop should now start up and you can plug in AC power.

If it still won't turn on after this then chances are you flashed it with the wrong BIOS update.

Good luck.

I have Acer Aspire 1640Z notebook and I tryed to update the bios but it was not succesfully updated and power off . when I power on its give me 1 long and 2 short beeps and blank screen . How do i reset...

The only thing you can do that I am aware of, is attempt to remove the battery and unplug the system. Then remove your CMOS battery which is usually located under the keyboard.

If you do not feel comfortable disassembeling your PC then dont do it!

But, if removing the CMOS BAttery does not work, you might be out of luck. Improper installation or updating of your BIOS in many cases will render your PC inoperable, I hate to say that, but they warn you of this before the installation starts!

Let me know what you find or if you need more assistance!

Bios reset on a acer aspire 1640z

To reset the bios in a laptop you need to unplug the power supply and remove the battery. Once you do that press and hold the power button for 45 seconds then put the battery back on and plug it in and then try starting it. Everything in the bios will be reset to the factory. 
Good Luck

How can i get update for Bios

Hi there.

You can download the BIOS update from the Acer website here:

Just select your make and model, then underneath that, select your Operating System. Then just click on the BIOS tab, then the orange icon to the left of the BIOS file.

Hope that helps.
