Travelmate 4000 disassemble

Hi! A few days ago my graphic card started to have a strange behavior, but only during startup (have some vertical pink lines in half the screen) and when the 3D rendering starts. I've reinstalled all drivers and the problem continued. Then I thought it was overheating problems and, even though I was able to clean in from under it, it wasn't enough :(
Can anyone tell me or send me a manual on how to take the laptop apart? Thanks

P.S. - My e-mail is

    After the drivers installation I had reinstalled Directx9c but that wasn't the problem. I don't have pixels or those lines in the LCD on the desktop or any 2D applications. The problems starts on games or 3D applications, so I'm guessing it's a rendering problem... There is also the possibility of the graphic card memory/chipset being a bit fried but I hope it's "only" and overheating problem.
    About the service manual I already have it, so I was looking for an "instruction manual" on the 1st steps to take, specially on what to do to remove the keyboard and the front

  • Radu Lykan Apr 05, 2008

    ok, thanks :) I will try to reinstall all (I have an external 2.5HD so I will transfer that disk to the laptop and try to reinstall all). I will have to wait a week before I can try this cause It happened to me while I am away from home and don't have the CD's with me. I'll put here if it worked or not. Thanks

    I friend o mine has a Aspire 1680 with the same graphic card, so I swap is HD with mine and restarted my laptop. His works well, but I cannot say the same with mine. Whenever the Direct3D is used the graphic card has the same behavior :( Seems my chipset is really defective. Thanks for the help

    i've got the exact same problem....BUT there is some sort of temporary solution that at least works for me

    [[first of all: if anyone happens to know, how to disassamble this notebook, let me know....i'd really appreciate that]]

    after i'd lived with the lines covering my screen for quite some weeks, i took my notebook to a friend (apart of the lines it just works fine in 2D mode) and happend to see, that each time, the nootbook was moved with a little force, the visible lines rearranged. that means, i've got a loose contact.
    before i tried to disassamble the notebook again, i did a little search and found this forum here, so hopefully, the links presented do me any good. since you've got the same problem, i'll explain, what i did, in order not to get it any worse and in the best case to let the lines on the screen vanish:

    first of all the problem:
    on startup, when you see the big ACER logo, covering the output of the notebooks bios, one will see red lines from top to bottom and from the middle to the right of the screen.
    in the worst case scenario you'll have the same with the windows bootup screen, only in blue and some flickering dots...don't be scared by that, i only call it worst case scenario, because you can let that vanish with a little "trick" i will explain afterwards.
    after that, one will see red lines all over the screen, while on the windows desktop

    so much for the problem. now, lets look at my temporary fix for that:
    first of all, set the color depth of your screen to 16bit....while in 32bit mode, you will have a lot of thin red lines on the screen, in 16bit mode, you will still have lines, but in blue (much better to work with) and they've got kind of the have resolution compared to the red lines.
    now don't hang me up on the red and blue lines. the color of these lines actually changes depending on the color of the window or desktop picture you've got in the "background" behind the lines (for me its blue on a dark background and light orange on bright backgrounds...for instance if you've got a black desktop, you'll see blue lines, if you open an explorer with its white background, you will see orange lines)

    the next step is the installation of the omega drivers (first link in a search for "omega drivers" on google). with these drivers you'll have control over the clock speeds of gpu and gpu memory using the ati tray tools shipped with it.
    after installation, use the tray icon of the ati tray tools, to access the overclocking settings. we don't want your graficcard damaged any more so you should set the clocks of gpu and memory to the lowest value possible befor the screen acts even more funny due to a clock that is set to low. for me core speed: 398.25 and memory speed 168,75 works just fine.
    (you should read about this tool on the internet before trying it out if you don't know what you are doing)
    after applying this any flickering, that is still present, should stop. to look for any flickering, you can use any black window (for instance the command promt window (cmd.exe))

    the final step is to stop any hardware acceleration (somewhere in the graficcard settings, you can access from where you can change the resolution and color depth of the screen....sry, but i use a german windows version, so you'll have to look that up on your own)

    after doing all of these steps you hopefully won't see any lines any more but some kind of a dot matrix (not the optimum but at least much better to work with)

    and now the little trick:
    if you press the right shift-key (press hard but don't break anything), the lines/dots/whatever should vanish.
    if you do this while the notebook is still cold, the screen should present itself like there isn't any damage at all....while the notebook gets warmer, it becomes more likley, that the lines will vanish, while you hold the shift-key but will reappear, if you let go of the pressure (if you are lucky, you'll have a whole day without them or even more)

    i hope, that this helps a bit....i am NOT a professional and i came up with these things on my own, but it works for me at the moment.
    i can work with it and it does't get any worse, so hopefully you can do the same thing and live with it

Reinstall direct x before disassembling the laptop. If the problem is hardware is likely to be LCD display to be replaced, LCD ribbon cable out of place, or graphic chipset defective.Here is download of part list and explode view for your laptop. You can require service manual or schematics for travelmate 4000 on this forum, or check older posts and see if you can find it.

    You can hope whatever you like. It is not a CPU overheating problem, as the laptop shut down when youy have such a problem.If the graphic chipset overheats , then is defective. Graphic chipset is not supposed to have a have a fan and there is no room for placing one inside. If you have the problem only when you play videogame then can be just a matter of compatibility with your graphic chipset.
    I suggest you not open the laptop, you can cause further damage if you do not have right knowledge. Thanks for negative rating given.

    If your graphic chipset start displaying weird lines or pixels on screen, always after a while, even when you do not use a game, then there is graphic chipset overheating (this is not quite frequent) If it happens to a laptop it is quite a serious problem, and cleaning will not solve the graphic card is integrated into MB, and there is no way to replace the chipset. In your case it is probably a system problem of some kind. If you have a spare 2.5 hd, you can try to reinstall system on a different hard disk, possibly from recovery disks, and see if you still have the problem.
    Let me know if you hve more queries.

How to locate the Cmos battery

The CMOS battery is the RTC battery. Real Time Clock.

It's smaller version of the CR2032 batteries you're used to seeing in a desktop computer.
It's in a plastic holder that resembles a bag. The plastic 'bag' wraps around the battery.
There are two wires attached to the battery, and come out of the 'bag'.

One wire connects to the Positive pole of the battery, and the other wire connects to the Negative pole.
The wires are soldered to the Battery.
At the end of the wires opposite of the Battery is a small white connector. It's a Male connector.
The Male connector plugs into a Female connector on the motherboard.

Once you have the RTC battery pack removed, and the battery itself removed out of the 'bag', you can match up a new battery to it. Carefully make a **** in the side of the bag, and remove the battery/wire combo.
Have a competent repair person remove the wires, and connector to the old battery, and solder the wires/connector to the new battery.
Install the battery/wires/connector combo back in the 'bag', use glue to seal the 'bag' once more.
(Or you can use silicone)

The RTC Battery is on the BOTTOM of the motherboard. This means the laptop has to be completely disassembled in order to access the RTC Battery.

In the above heading it states Acer TravelMate 4000 PC Notebook. This is the TravelMate 4000 series.
There are many models in that 4000 series.
The Model Number is on the bottom of the laptop.

Models in the 4000 series are; 4000, 4010, 4020, 4050, 4060, 4070, 4080, 4100, 4150, 4200, 4210, 4220, 4230, 4260, 4280, 4320, 4330, 4330G, 4400, 4500, 4520, 4530, 4600, 4650, 4670, 4720, 4730, and 4730G.
The above Model list may not be complete.

The disassembly guide for the Acer TravelMate 4000 series will cover all of the above models.

Scroll down with your eyes to the Travelmate heading.
Go down to the third line that starts with 2700, read across to 4000.
Click on 4000.

This is a PDF file. The computer you are on now has Adobe Reader on it, which uses PDF files.
However if you do not have the latest Adobe Reader, I would suggest downloading it.
(Adobe Reader 9.3.4)

After you click on 4000 nothing will happen for up to 30 seconds. (Maybe more)
The screen will be blank. The file is downloading in the background, and after it has fully downloaded, the first page will pop up.

For additional questions please post in a Comment.
Would appreciate it if you would rate my solution.

I have acer travelmate 290 while working suddenly the screen went white and the remained so i turned it off and now i try to start it power comes on but display shows nothing. tried removing HD and Drive...

I have the exact same problem with my old computer! The problem started after I switched the HDD a long time ago but I never got it (semi-)working again until a few days ago.I completely disassembled the computer and reassembled it again and I finally got something on the screen. I the tried to install win xp but when I pressed the keyboard the problem reoccurred. Therefore I'm fairly sure there is a short circuit or a bad connection somewhere probably on the underside of the motherboard close to the power supply DC-connector.

Acer Travelmate LCD screen went dark

The same thing happened on my HP. I ended up buying a LCD screen off ebay. That corrected the problem. New screens cost $150+. You can get one off ebay for half the price.

Dell Inspiron Display goes black

My guess is that your laptop's graphics card is goinf out on you. If your computer has an Intel embedded graphics card, then you will probably have to replace the whole display itself; if it has a dedicated graphics card such as NVIDIA or ATI, then you ight only have to have the graphics card.

Icons green tint to them

I'm not sure but I think this model uses an integrated graphics card which would then involve replacing the entire motherboard.

It may be that the screen backlight is getting old - they often age by showing a tint, usually it is pink but I have seen them go greenish.

Try an external monitor connected to the laptop via the VGA d connector. If the picture on the external monitor has a good colour balance then it is probably not a faulty graphics chip, and likely to be the laptop screen.
