Question about Acer Aspire 1640Z Notebook

1 Answer

When Win XP restarts display is black.

When Win XP is shut down and restarted, the laptop emits a loud beep and appears to reboot with the display blacked out. If I then connect to an external monitor, the Windows XP splash screen is displayed on that. When the Windows logon dialog is to be displayed it then automatically appears on the laptop display, and the monitor loses its display role. For the rest of the work session the laptop behaves normally.

SOURCE: My FN+F6 doesnt keep my screen on the laptop open

Change the settings from the display settings panel. (Right click on the desktop and go to display settings)
You should see 2 monitors graphically represented there. 
You can make the monitor that is greyed out active by right clicking on the monitor, and selecting active.

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: Was dropped. Screen very dim.Keeps restarting.Ideas?

Hello, Paul. Your grandson's notebook's problem could be originated from number of things (caused - or not - by the fall). Let's break it down into two problems (which are probably unrelated): the restarting and the dim screen.

There's a very good troubleshooting guide online by Morris Rosenthal. You can check it here.

About the dim screen

On the aforementioned guide, which i'll be quoting from now on, you'll find particularly relevant information for this case: "Dim desktop image? Can you see a ghost-like image of your desktop that is functional, ie, one that changes if you drag an icon, launch a program or disappears if you shut down. Standard LCD screens produce very little visible light on their own, they require the Cold Cathode Fluorescent Light (CCFL) to light the screen from behind. The fluorescent tube is normally located at the top of the screen, and a bright reflective surface distributes the light across the back of the LCD, so it can shine through the liquid crystals of the liquid crystal display, which only transmit red, green or blue (RGB)."

When you say it brightens, it probably does so in sort of a tinted way.

"Red, orange tint, uneven? Is the entire screen tinted red or orange (probably growing worse over time) or is the background brightness of the screen uneven, particularly near the edges? The tin is caused by a failing backlight not putting out the full spectrum of white light, so the CCFL tube needs to be replaced."

This gives us some information about the backlight that is used in LCD screens, but there's also another component in play, which is the inverter. A damaged inverter is *the* greatest cause for failing notebook screens. Your grandson's notebook's backlight could be fine, but a damaged inverter may not be sending it enough current for it to work. I could only tell you exactly which one is at fault here by running some tests on it, but this information points you to the very likely source of the problem.

About the restarting

This problem unfortunately has a wider range of possible sources, ranging from OS-related problems (like viruses and a corrupt installation), faulty/misconfigured hardware (or drivers), overheating (though the computer usually shuts itself down when it overheats, instead of restarting. It depends on your available BIOS settings) and many others.

I hope this information was helpful, and i advise you to get that lappie checked by a qualified technician.

i know your problem. even if you change the inverter it will not work. the real problem of your notebook is vga memory or video memory. use hot air to resolder your memory. trust me!

SOURCE: Screen not working on ACER 5315 laptop

First be sure you dont have an imput problem on your laptop while you are testing it. The input buton (swtich view) should be acessible via the Fn button and the F3-F8 on the keyboard (depends on your model) but it could looks like this : |[]| it really depends on the brands/models. It seems you experience some driver issues, but the driver should work for both devices... It's possible that your laptop screen or inverter are defective. But before saying so, be sure to try to switch views while you got the external monitor plugged in and see what happens. If only your external monitor works fine, you may have to replace some hardware in your laptop. I would personally contact the Acer technical support before spending any money on it though. Just in case... I hope it still in warranty cause it may be a bit expensive otherwise :(

Gateway MT6840 unexpectedly shut down and wouldn't


First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty.
Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

I need to reboot my laptop but i don't know how


Reboot essentially means restarting the computer. This is two types
1. Warm Reboot: where you go to start on windows task bar and choose shut down but when prompted choose restart. This way computer shuts down momentarily and restarts!
2. Cold Reboot: By this means you choose to shut down and again when prompted choose shut down! This makes computer off completely until restart by pressing power button.
Booting is computer Lingo for above procedures!

Studio 17 laptop stalled during uploading of a music cd into ITune libray. Manual shut down and reboot resulted in stalling of reboot process at 3/4 of the status bar with only the dell logo on black...


AS YOU ON THE SYSTEM AND EVEN BEFORE WINDOWS STARTS KEEP PRESSING THE F8 KEY CONTINUEOUSLY. A MENU WILL APPEAR. SELECT SAFE MODE AND ENTER. WINDOWS WILL LOAD IN SAFE MODE. THIS WILL SOLVE SOME OF YOUR PROBLEMS. NOW RESTART THE SYSTEM IN NORMAL MODE.

IF THIS DOES NOT WORK SELECT "LOAD WINDOWS WITH LAST KNOWN GOOD CONFIGURATION " AND THEN RESTART. THIS WILL SURELY SORT OUT YOUR PROBLEM.


PLS REPLY OR COMMENT. THANKS

How do I reboot my acer laptop with my copy disk?


When turning your laptop on, before Windows starts booting, a splash screen appears first (usually with the logo of the manufacturer). Look on the splash screen (usually at the bottom) for a key (usually F10 or F11), assigned for System Recovery CD/DVD with the laptop. or 1.Press the start button from the start menu depending on your operating system(win 2000,xp) 2.Press Ctrl+Alt+delete combination from the keyboard. 3.If you have a power button on your laptop keyboard,it could also be useful by pressing and hold it down for few seconds N.B: "Ctrl+Alt+Delete" can exit you from usage and trigger a reboot or shutdown. Try and reboot using the operating system. Attempt to use the key combination that will allow you to exit from the operating system and restart the laptop. Be patient, as it may take some time if it has locked up. Hold down the power button. If the operating system's answer to the rebooting will not work, find and hold down the power button of the laptop. This should cause the device to shut itself off. You'll have to press the power button again to power it back on, completing the reboot. Unplug from the wall and remove the battery. If restarting via the operating system and the power button do not work, unplug the laptop from the wall outlet, and remove the battery from the laptop. This will cause it to power off immediately. Allow time to reboot. Give the laptop time to cool down before you power it back on if you had to do this manually. A few seconds should do unless you have additional problems.

All the Best!

My computer won't shut down it just keeps restarting


The most common shut down problem is that the system will reboot rather than shutting down. In most cases, the reboot is triggered because Windows XP is designed to reboot after a critical failure. To stop windows from rebooting in case of a failure, you need to take the following steps:
Right click on My Computer, Select Properties, Click on advance tab, Click on Settings under Startup and Recovery, Uncheck the option Automatically Restart under System failure, Click Ok twice and try to shutdown the pc. If it shows any error code then let me know

Can not save to bios


windows and the bios needs to know that the operating system can be shut down through windows, so when you go into the F2 or Del on boot up, go into advanced cmos setings and look for ACPI and make sure it is enabled. This sets the motherboard to support shutdown. Save and exit settings and reboot. Now go to control panel>performance and maintanance>power options and set the correct instruction for shutdown to shut the pc down. Remember evertime you remove the cmos battery or reset with jumpers you have to reset date and time and anything else you have changed to suit your set up
