Acer aspire 2003wlmi inverter problem?

[jelenap]

When I start laptop, somewhere before welcome screen at windows starting, I heard sound of starting windows but my screen stay black sometimes whit few white strips, and sometimes it stay all white. After that I press ALt+F5 twice to get computer from stand by and my computer works OK, just aperd desktop screen.
I send it to the main Acer in Italy they something change (inverter they told me) but after some time I get same problem at same place again. That 'problem is not offten.

I don't know way after they change that inverter I have same problem. That problem is just on the first start of windows in the day, and once or twice times in the mount.
can someone tell me can that be problem whit inverter, or whit something else. and if someone can help me I will send over the e-mail some shoot photos of process of starting my laptop whit that problem.
I have Acer aspire 2003wlmi, and that laptop is great but ...

please sorry about my english.

does the bios post screen which is text, display without problems and it's only once the graphic environment of windows is displayed that the problem arrises? If so you might want to try updating the video drivers to the latest version and if that doesn't help then it definately sounds like a hardware fault which acer should be responsable for

[cadaveca]

sounds like STR....

[Áedán]

The inverter is just a voltage converter that's used to run the backlight. Most backlights are cold cathode tubes, so need a few hundred volts to work properly. It doesn't sound like a problem with the inverter, as that would cause the backlight to fail.

Sounds like an issue with something else, such as a connector or the LCD controller.

[jelenap]

That is Ok but why they (Acer service) change inverter. I can mail picturs of starting process to someone who want, to see my problem.

And please what is STP and POS?

Please anyone who my know something be free to write here. THANKS

Sounds to me like it may be a problem with your video drivers wigging out when your machine goes into 'suspend' mode (that's what Cadaveca was refering to with STR 'Suspend To Ram'). Although Áedán has a good point about the connector and controller. In any event, it is going to be very difficult and time consuming to diagnose, I would imagine.

[jelenap]

OK STR but way just some times. Not every time I start my laptop. Sometimes twice in a few days sometims one in mounth.

I don't have right now my laptop here, I would hy+ve it tomorow and I wolud see in BIOS that STR.

[cadaveca]

that's what makes me think that...it only being sometimes. It sound as if your battery is low and it gors into stand-by, or maybe STR, so the battery can be charged. I dunno...the screens would help.

[jelenap]

Most of the time I'm working without battery, only whit AC cable and battery is out of laptop.

Thanks!

Does your laptop have a tv-out option?

[jelenap]

Yes. S-video connector.

[Gizmo]

Is that option disabled in the BIOS? I can't help but wonder if the thing is coming up thinking that it needs to be sending the video to the S-video connector instead of the regular VGA connector on a cold boot.

[jelenap]

I figure out that also when I press Fn+F5 (changing of displays) I get immediately the desktop picture.
You have right. Maybee this laptop have problem whit external displays. They work OK, but everytime when Windows start at the same place I have that problem. It looks like the laptop shearching the Nther display. Sometimes everthing went OK and sometimes I have problem whit black screen. Maybee some connector it's not placed how must be. What you think.

[cadaveca]

Sounds plausible...have you tried using an external display? sounds like there is a driver setting that has the external output as primary display, possibly.

[cadaveca]

I can almost positively say that the problem is not with the inverter(which simply lights the back of the screen). If the inverter where the problem, you would still faintly see the login screen image under good lighting conditions...you really need to look hard, but it should be visible.

I am not sure, but i think your laptop has a Mobility 9700. This version of the 9700 differs slightly from the pci part, and as far as i can remember, requires a specific driver. I recall reading something about the ?power-management?...I'll have to dig up the whitepapers and have a look. I have dealt with a similar problem when having a pc alternate between LCD and CRT, but it's bit fuzzy.

[jelenap]

i have Mobility 9200 with 64 MB, and I have originaly drivers for graphic card and I was looking for new drivers but on the ATI web page I find that they don't have a new drivers for ATI mobility chips. On the ACER web page I did not find a new version.

At device manager I find three default monitors. I think that one is for LCD, one for external CRT and one for S-video external. Can I disable two external displays and just leave one because I don't use it. Which one I must disable. First in the list is it the LCD display.

[cadaveca]

lcd would be your laptop screen, crt the 15-pin out, and s-vid for a tv. I would disable all but lcd, i think.


make sure that the LCD is set as primary...right-click desktop, select properties, and on the settings tab there should be a place where you can set the lcd as primary...
i really think that there is some application that is causing it to default to another output as the primary on boot, instead of the lcd screen that is attached.

inverters aren't problems unless you have a broken hinge(the wires travel through the hinge), or have hit the back of the screen really hard. I paid $250 US for 5 inverters (well, my client did), and most shops charge about $1000 for the repair. Takes about 20 minutes to replace one too.

[jelenap]

I disable the crt and s-video display, and now we will see.

I think non stop about my problem. I saw always on the starting windows at point when my problem start, I always saw little longer black screen. On that transition between screen of starting windows (LOGO of win on the black sreen) and the blue screen with Welcome.

I comper that with my desktop home PC and that transition on my desktop PC is very short.

[cadaveca]

I understand what you mean...and the behavior that you describe is what happens while the display driver is initialized. You'll find that the time differs, not because of the pc/laptop difference, but because of the difference in the display devices. This can also change dependant on driver, although i find that it is seldom, as we are talking about the 2-d side of the card, and that rarely gets changed.

The more you descibe, the more I am beginning to believe that it is a driver that is the root of all of your problems. PLease keep us updated!
