Could be the cmos battery low voltage, the processor may be too hot, the video firmware may have errors ... could be all manner of things.
Try updating your drivers after checking the cmos battery.

SOURCE: acer 1640z boots up fine, but no post screen and bleeps

Dear all,

I also posted this one under "Notebook Bios Problems" which might not be the correct place. Anyway here it is for you to see and maybe you can 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 should I use i.e. how do I know if I need the AT or UMA version - how to verify this on the notebook (my version is 1642 ZWLMI)?

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

LATEST NEW - it WORKS AGAIN:
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: http://www.rechner.org/b1800.html ).
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
to BIOS.WHP.
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
20: THE LAPTOP IS BACK AND THANKS TO ALL OF YOU I SAVED A LOT
OF MONEY icon_lol.gif

This worked for me and only cost me £5, Here is the web sit i got it from
http://www.wimsbios.com/phpBB2/topic9512.html

Hope it works for you

SOURCE: my acer 5520 will power up but does not boot. the

I believe that you have a bad system board. If you can get onto acer support and send a message to ther technical staff, I think that they will confirm this diagnosis. If you were dealing with a hard drive problem, the computer would try to start up and give you some type of error message on your screen. Additionally, your power supply for a laptop is on the system board, unlike a desktop where the power supply is separate from the system board. I am assuming that your have confirmed you are connected to a power supply and your problem is not a lack of power (a bad battery). Please rule out the power question first.

You can also try to remove all power sources from the laptop and let it sit for a time, then attach the power and see if it resets and starts up. (this is a simple thing you can do to attempt to recover you laptop. I suggest you try this, but don't have much hope it will change anything)

I am sorry I do not have more positive news for you. However, I hope that this information gets you on the right track to solving your problem.

Screen not displaying. and fun starts and stops, remains stand by when restarted the fun runs and stops stand by.


hello there,

I got the same problem but it came gradually...

In fact for a full month when I first boot the computer, the fans runs, no extra beeps, the light blinked correctly but no bios at the screeen. I remarked also that the fans run full speed doing a lot of noise. Then I stopped the computer and wait 2 minutes and then it always works correclty at the second boot with the bios screen appearing. Also, the fan calm down after 1 second with less noise. So when I start the computer and hear that the fan calm down with less noise after 1 second, I know that the computer will boot correctly. That happens always at the second try after waiting 2 minutes. But since yesterday, the fans never calm down and the noise still remains high with no Bios at the screen. I'm suspecting the Power Supply...

i hope my i dea can help you.

Dell power edge 2850 make 4 seconds beeps alarm without stopping and without show any error Msg on the screen.


I don't understand the beep code you describe, but the 2850 has many beep codes to help understand what is going on.

First ... Identify the beep. Does the beep start as soon as you power it on, or after several seconds? What is the pattern of the beep - is it a repeating set of beeps - 3 sets of beeps between 1 and 4 beeps ... like 1 beep-3 beeps-2 beeps, or 3 beeps, 3 beeps, 1 beep? Or is it a steady repeating beep - about once per second?

Second ... is the LCD panel on the server blue or orange? If orange, what is the error code(s) it is scrolling?

If it is a steady, once-per-second beep, it is probably your RAID controller. Does the system boot to Windows/OS ok? If so, use (or install) OpenManage Server Administrator (Managed Node from Dell's Support Site) to check the Hardware Logs and check the RAID array (under Storage/Virtual Disks). If it is not booting to the OS, then go into CTRL-M to see what the status of your array is.

My ps3 has stopped connecting to the internet, checked internet and it is working, how do I sort it?


I had the same problem. What you can try is go to the recovery menu. Turn the PS3 onto standy (red light on). Press and hold the power button. It will beep as soon as you hold it, keep pressing it until it beeps again and then once more 5 seconds later. The system will switch off. Press and hold the power button again, 1 beep straight away, then another 5 seconds later then 2 quick beeps, let go of the power button. It will now boot into the recovery menu. Select restore file system. It will restore and then reset. Hopefully this will solve it for you.

Will not start up


If it's not beeping during the first start up then it's not POSTing.  Beep means everything connected to it seems to be functional ie PnP  
Try pulling out your memory and reseating it.   Try pulling out your battery for 5 minutes then plug in ac(without batt) and see if it will boot.  Try pulling your hard drive and reseat.  (access by covers on bottom...dont be scared. Touch something that's grounded just before you remove) If all this and still no full POST(with beep/s) then sounds like a new mobo or processor.
